CMA Practice Test

Answer: A
Subtract 32 from the Fahrenheit reading and multiply by five ninths: 101.3 minus 32 equals 69.3, times 0.5556 equals about 38.5 degrees Celsius. A useful sanity check is that 98.6 F equals 37 C, so a reading a few degrees Fahrenheit above normal should land only about one and a half degrees Celsius above 37.

Answer: A
A cuff that is too narrow requires more pressure to occlude the artery, producing an artificially elevated reading; an oversized cuff produces a falsely low one. The bladder should encircle roughly 80 percent of the arm and cover about 40 percent of its circumference in width, with the arm supported at heart level.

Answer: A
Typical adult resting ranges are a heart rate of about 60 to 100 beats per minute, a respiratory rate of about 12 to 20 breaths per minute, and a temperature near 37 degrees Celsius. Values outside these ranges are reported to the provider, and a repeat measurement confirms an unexpected result before escalation.

Answer: A
Orthostatic measurement compares a supine reading with a reading taken after the patient assumes an upright position, with a short interval to allow the pressure to respond. A significant drop with symptoms such as dizziness suggests orthostatic hypotension, and the patient should be guarded against falling during the maneuver.

Answer: A
The deltoid is a small muscle and generally accommodates about 1 mL in an adult, while the ventrogluteal site accepts larger volumes. Injection technique includes selecting an appropriate needle length for the site and patient, using a 90 degree angle for intramuscular administration, and never recapping the needle before disposal in a sharps container.

Answer: A
Subcutaneous injections use roughly a 45 to 90 degree angle, chosen by needle length and the amount of subcutaneous tissue, with a shorter needle allowing a steeper angle. Intradermal injections use about 10 to 15 degrees to raise a wheal, and intramuscular injections use 90 degrees.

Answer: A
The rights of medication administration require verifying patient, drug, dose, route and time against the order, with documentation completed after administration rather than before. Patient identity is confirmed with two identifiers such as name and date of birth. A patient's expectation does not substitute for verifying the order.

Answer: A
Vasovagal syncope after a procedure is common, and the immediate danger is injury from a fall. Support the patient down safely, then summon assistance and monitor. Leaving the patient unattended risks a fall, and giving oral fluids or asking a syncopal patient to ambulate can cause aspiration or injury.

Answer: A
Limb electrodes are placed on the four extremities on fleshy areas, avoiding bone, while the six precordial leads are placed at specified chest positions. Placement accuracy matters because misplaced electrodes produce artifact or a tracing that mimics pathology, and the tracing is a diagnostic record the provider interprets.

Answer: A
A clean-catch midstream specimen in a sterile container minimizes contamination from skin and periurethral flora, which would otherwise produce misleading culture growth. The patient receives specific cleansing instructions, and the specimen must be labeled at the point of collection and processed or refrigerated promptly.

Answer: B
Labeling at the point of collection with the patient present is the control that prevents specimen misidentification, which can lead to a patient being treated for another person's result. Batch labeling afterward introduces exactly the ambiguity the rule exists to eliminate, and laboratories reject unlabeled or mislabeled specimens.

Answer: A
Amoxicillin belongs to the penicillin class, so a documented penicillin allergy is a direct contraindication that must be raised before administration. Verifying an apparent contradiction is within the assistant's responsibility and is a core patient safety function. Test dosing and altering the allergy record are both outside scope and dangerous.

Answer: A
PO means per os, by mouth. Other common route abbreviations include IM for intramuscular, IV for intravenous, SL for sublingual and PR for per rectum. Certain abbreviations appear on do-not-use lists because they are frequently misread, and any ambiguous order should be clarified with the provider before administration.

Answer: A
A fasting specimen requires abstaining from food and caloric beverages for the specified period, with water generally permitted and encouraged to maintain hydration for the draw. Prolonged fluid restriction is unsafe and makes venipuncture more difficult. Eating before the draw invalidates the fasting result.

Answer: A
Divide pounds by 2.2 to obtain kilograms: 44 divided by 2.2 equals 20 kilograms. Accurate weight conversion matters because pediatric medication dosing is weight based, so an error propagates directly into the dose. Multiplying instead of dividing produces 97, a value that should immediately appear implausible for a child.

Answer: B
The lithotomy position, with the patient supine, buttocks at the table edge, and feet in stirrups, provides the visualization and speculum access required for pelvic examinations and Pap specimen collection. Knee-chest is used for some proctologic exams, Trendelenburg is a shock or surgical position, and flat legs prevent adequate access.

Answer: B
Cleaning proceeds from the cleanest area to the dirtiest, which for a wound means starting at the wound itself and moving outward, discarding each swab after one pass so bacteria from surrounding skin are never dragged into the tissue. Inward or back-and-forth strokes recontaminate the wound bed and increase infection risk.

Answer: C
Using the ratio method, the dose equals the ordered amount divided by the on-hand strength times the vehicle volume: 100 mg divided by 125 mg, multiplied by 5 mL, equals 4 mL. Choosing 5 mL confuses the labeled reference volume with the calculated dose, and 2 mL or 8 mL come from inverting or misapplying the proportion.

Answer: D
An irregular rhythm makes short radial counts unreliable because beats may be weak or missed at the wrist. Counting the apical pulse for a full minute captures every beat and should be reported to the provider. Simply documenting or delaying assessment could allow a dysrhythmia to go unevaluated.

Answer: D
The apex of the adult heart lies at the fifth intercostal space along the left midclavicular line, so heart sounds are loudest there. The right sternal border at the second interspace is an aortic auscultation point, and the xiphoid and axillary locations do not overlie the apex, producing faint or absent sounds.

Answer: A
Blood pressure is measured accurately when the cuffed arm is supported at heart level; an arm below heart level falsely raises the reading, while an elevated arm falsely lowers it. An unsupported arm requires muscle contraction, which also elevates the measurement, so passive support on a surface is essential.

Answer: C
Patients who know their breathing is being observed often change their rate or depth involuntarily. Keeping the fingers on the wrist as if still counting the pulse lets the assistant observe chest rise unobtrusively, yielding a natural rate. Announcing the count or delegating it to the patient introduces conscious control and error.

Answer: C
Dark nail polish, poor perfusion, and motion can block or distort the light transmission a pulse oximeter depends on, producing falsely low readings. Because the clinical picture does not match the number, the assistant should eliminate the interference and remeasure before acting. Treating or documenting an artifact as real data would be inappropriate.

Answer: D
In adults the external auditory canal is straightened by pulling the pinna upward and backward, which lets the tympanic probe aim at the eardrum for an accurate infrared reading. Pulling downward and back is the technique for young children, whose canal anatomy differs, and would misalign the probe in an adult.

Answer: D
Sims' position, with the patient on the left side and the upper knee drawn toward the chest, relaxes the perineal area and gives the provider the best access for rectal examinations and enema administration. Supine, prone, and semi-Fowler's positions do not adequately expose the anal area and would make the exam difficult and uncomfortable.

Answer: B
Elevating the head and chest in Fowler's position lowers the diaphragm, expands lung volume, and eases the work of breathing, which is why it is preferred for dyspneic patients. Lying flat increases venous return to the heart and worsens pulmonary congestion in heart failure, and prone or lateral positions restrict chest expansion.

Answer: D
Snellen screening is performed at a standardized 20-foot distance, testing each eye separately while the opposite eye is occluded without pressure, since pressing distorts vision when that eye is tested next. Squinting artificially sharpens focus and invalidates results, and patients who wear corrective lenses are typically screened as directed with them in place.

Answer: A
The Ishihara test uses plates of colored dots that form numbers or paths visible only to patients with normal color perception, making it the standard screen for color vision deficiency. Peripheral fields are assessed by confrontation or perimetry, and near accommodation is screened with reading cards, so those answers describe different tests.

Answer: C
Shivering and tense muscles generate electrical activity that appears as irregular, jagged spikes called somatic tremor artifact; warming and relaxing the patient usually resolves it. AC interference produces a uniform thick baseline of small regular deflections, and a broken wire typically disrupts specific leads rather than adding jagged noise everywhere.

Answer: A
A wandering baseline usually results from poor electrode contact caused by loose sensors, lotion, oil, or excessive movement, so reattaching electrodes to clean, dry skin is the first fix. Changing paper speed alters the waveform display rather than the drift, deep breathing worsens baseline sway, and outlet changes address AC interference instead.

Answer: A
V1 is anchored at the fourth intercostal space just to the right of the sternum, and V2 mirrors it on the left side; the remaining precordial leads are then positioned relative to these landmarks. The fifth interspace at the midclavicular line is the V4 location and the midaxillary placement corresponds to V6, so those sites would misrecord the septal view.

Answer: D
The fleshy side of the middle or ring finger has fewer nerve endings and good capillary flow, and puncturing across the fingerprint ridges helps blood form a rounded drop. The central pad and thumb are more painful and calloused, and strong squeezing dilutes the sample with tissue fluid, which can distort glucose results.

Answer: C
Leaving a tourniquet in place too long traps and concentrates cells and large molecules below it, falsely elevating analytes such as potassium and protein — a phenomenon called hemoconcentration. Releasing within roughly one minute preserves specimen integrity. The needle itself does not clot from tourniquet time, and no statute governs tourniquet duration.

Answer: A
Forcing blood through a narrow lumen and shaking the tube ruptures red cells, releasing hemoglobin and intracellular contents that discolor the serum and invalidate many chemistry results. Lipemia relates to fasting status, not handling, and neither low volume nor clotting is directly produced by needle gauge combined with rough mixing.

Answer: B
After lymph node removal, the affected arm has impaired lymph drainage; constriction or puncture there raises the risk of lymphedema and infection, so the opposite arm is used and the precaution documented. A looser tourniquet or hand vein on the affected side does not remove the risk, and a fingerstick is unnecessary when the other arm is available.

Answer: A
When a patient faints during a draw, the immediate priorities are stopping the procedure safely and preventing injury: release the tourniquet, withdraw the needle with pressure on the site, and support the patient into a safe position. Continuing to fill tubes or leaving a needle in a fainting patient risks laceration, needlestick, and a fall.

Answer: C
A butterfly set with a smaller-gauge needle and reduced tubing angle gives fine control for shallow, fragile veins, and pairing it with gentler draw pressure keeps the vein from collapsing. Strong evacuated-tube vacuum and large needles are exactly what cause fragile veins to flatten, and hand veins are an acceptable venipuncture site when handled correctly.

Answer: D
Quality control exists to prove an instrument is producing reliable results; a failed control means every patient value is suspect until the cause — expired strips, bad control solution, or meter malfunction — is corrected and a control passes. Testing patients anyway, averaging values, or picking the lower reading would report numbers with no analytic validity.

Answer: B
Each reagent pad develops color through a timed chemical reaction, so results must be read at the manufacturer's stated intervals; reading early or late produces false values. Strips are dipped briefly and excess urine removed rather than left soaking, color charts are brand-specific, and heating a specimen alters its chemistry and is never appropriate.

Answer: D
A 24-hour collection measures total output over exactly one day, so the bladder is emptied and that first specimen discarded to start the clock, then every subsequent void is saved through the final void at the same clock time the next day. Including the first void or skipping collections makes the timed total inaccurate and usually requires restarting.

Answer: C
Urine that has accumulated overnight is the most concentrated, so hCG levels are highest and early pregnancy is least likely to be missed on a first-morning specimen. Heavy fluid intake dilutes the hormone and can produce a false negative, exercise adds no benefit, and catheterization is an invasive collection reserved for specific clinical indications.

Answer: B
Snipping the suture next to the skin means the only material drawn through the tissue is the portion that was already beneath the surface; the exposed, contaminated segment never passes through the wound. Cutting mid-loop or yanking the knot drags surface bacteria through the healing tract, and leaving fragments behind invites inflammation and infection.

Answer: D
Wrapping from the far end of the limb toward the trunk supports venous return and prevents fluid from being trapped in the foot, while even overlapping turns distribute pressure. Wrapping downward or too tightly acts like a tourniquet, and the toes are left visible precisely so circulation can be checked for color, warmth, and swelling.

Answer: C
Numbness, pallor, and coldness distal to a cast are classic warning signs that swelling inside the rigid shell is cutting off blood flow and compressing nerves — an urgent problem that can cause permanent damage if the cast is not relieved promptly. These findings are never a normal adjustment, and atrophy develops slowly without acute color and temperature changes.

Answer: A
Properly fitted crutches leave roughly two to three finger-widths below the axilla, and the handgrips allow slight elbow flexion so the hands — not the armpits — bear the weight. Leaning on the axillary pads compresses the nerves of the brachial plexus and can cause arm numbness or paralysis, and locked elbows or splayed tips create instability.

Answer: B
Converting the order to the units on hand, 0.5 g equals 500 mg because one gram contains 1,000 mg. Dividing the ordered 500 mg by the 250 mg tablet strength gives two tablets. The most common error is misplacing the decimal during the gram-to-milligram conversion, which produces the half-tablet or five-tablet answers.

Answer: C
Z-track technique displaces the skin and subcutaneous layer sideways before injection; releasing the tissue afterward shifts the layers back, sealing the needle track so irritating medications like iron cannot leak upward and stain or damage subcutaneous tissue. It does not change absorption speed, dose volume, or permit needle reuse, which is never acceptable.

Answer: A
Repeated injections into the same spot cause fatty tissue to thicken or pit — lipohypertrophy and lipoatrophy — and insulin absorbed from damaged tissue becomes erratic, destabilizing glucose control. Rotating within a region preserves healthy tissue. Rotation reduces but does not eliminate discomfort, and insulin remains effective in any approved site.

Answer: A
The floor of the mouth is rich in capillaries, so a sublingual tablet enters the bloodstream within minutes and avoids both slow gastric absorption and the liver's first-pass metabolism, which would inactivate much of the drug. Speed is critical in anginal chest pain. The route does not eliminate side effects — headache and hypotension still occur.

Answer: D
Pulling down the lower lid creates a conjunctival pocket that holds the medication while it disperses; dropping onto the cornea is uncomfortable and triggers blinking that expels the dose. The dropper tip must never touch the eye or lids because that contaminates the bottle, and squeezing the lids shut forces medication out and into the tear duct.

Answer: C
Straightening the adult canal by lifting the pinna up and back and aiming warmed solution along the canal wall lets fluid flow behind the cerumen and flush it outward without striking the eardrum. A stream aimed directly at the tympanic membrane can cause pain, dizziness, or perforation, and positioning or irrigating the opposite ear serves no purpose.

Answer: C
Hives with airway swelling and dyspnea after an injection is anaphylaxis, a life-threatening emergency in which epinephrine is the first-line treatment and delay is the main cause of death. The provider is summoned, epinephrine given according to protocol, and emergency services activated. Oral antihistamines act far too slowly and observation without treatment wastes critical minutes.

Answer: B
Inability to speak, cough, or breathe signals a complete airway obstruction, and abdominal thrusts use diaphragmatic pressure to expel the object — the accepted response for a responsive choking adult. Giving water can worsen the blockage, isolated back blows without a protocol sequence delay relief, and laying the patient down is for unresponsive victims who then need CPR.

Answer: D
Seizure first aid focuses on preventing injury: lower the patient, remove hazards, cushion the head, time the event, and position the patient laterally afterward so secretions drain and the airway stays clear. Nothing is ever placed in the mouth because it can break teeth or obstruct the airway, and restraining or lifting a convulsing patient causes musculoskeletal injury.

Answer: C
Tremor, diaphoresis, and confusion in a fasting diabetic patient are hallmark signs of hypoglycemia, and a conscious patient who can swallow should receive fast-acting carbohydrate immediately, with the provider informed and glucose rechecked. Insulin would drive glucose down further and could be fatal, and delaying treatment for the blood draw or rest risks progression to unconsciousness.

Answer: A
HIPAA permits disclosure of protected health information for treatment, payment and health care operations, and otherwise requires patient authorization. Family relationship confers no right of access, and identity verification establishes who is asking, not whether they are entitled. Reading results aloud is the same disclosure as handing over a printout.

Answer: A
The minimum necessary standard limits use, disclosure and requests to the least information required for the purpose, and it applies to workforce access as well as external disclosures. It does not apply to disclosures to the patient, to the provider for treatment, or where the patient has authorized the release.

Answer: A
Informed consent is obtained by the provider performing the procedure, who explains the diagnosis, the nature of the procedure, risks, benefits and alternatives. The medical assistant may witness the signature and confirm the form is complete. Explaining risks or judging capacity exceeds the medical assistant's scope of practice.

Answer: A
Scope of practice is set by state law and delegation rules, and exceeding it is a violation regardless of outcome or patient consent. Liability commonly attaches to both the assistant and the delegating provider under respondeat superior. Patients cannot consent to care from someone not legally permitted to provide it.

Answer: A
Mandatory reporting categories typically include suspected abuse of children, elders and dependent adults, certain communicable diseases, and specific injuries such as gunshot and stab wounds. These override the usual confidentiality expectation. Declining care, changing providers and unpaid balances are not reportable events.

Answer: A
Abandonment is terminating care without reasonable notice and an opportunity to find another provider while treatment is still needed. Proper termination involves written notice, a stated period of continued availability and assistance with records transfer. Assault involves the threat of harmful contact, and res ipsa loquitur is an evidentiary doctrine in negligence.

Answer: A
Retention periods are set primarily by state law and vary, with longer periods for minors typically running from the age of majority, and federal and payer rules can extend them. The record is the practice's property while the information belongs to the patient, so a patient may obtain copies but may not order destruction.

Answer: A
HIPAA grants patients the right to request an amendment, and the covered entity reviews it and may accept or deny with written reasons and an opportunity for the patient to file a statement of disagreement. Original entries are never deleted; amendments are added so the record's history remains intact and auditable.

Answer: A
A durable power of attorney for health care, sometimes called a health care proxy, names an agent to decide on the patient's behalf. A living will states the patient's own treatment preferences but names no decision maker. Assignment of benefits concerns insurance payment, and a release of information authorizes disclosure of records.

Answer: C
The four Ds of negligence are duty owed to the patient, dereliction or breach of that duty, direct cause linking the breach to the harm, and damages actually suffered. All four must be present. Offer, acceptance and consideration are contract elements, and intent and publication relate to intentional torts such as defamation.

Answer: A
A subpoena is a legal demand but does not automatically authorize release of all protected health information, and HIPAA imposes conditions such as notice to the patient or a protective order in some circumstances. The correct step is escalation for legal review, not unilateral release or unilateral refusal.

Answer: A
Wave scheduling books a group at the top of an hour and works through them in arrival order, absorbing no-shows and late arrivals. Stream scheduling gives each patient a distinct time slot. Open hours means patients arrive without appointments, and clustering groups similar visit types together to use equipment and staff efficiently.

Answer: A
ICD-10-CM reports diagnoses, signs, symptoms and reasons for the encounter. CPT reports the procedures and services performed, and HCPCS Level II covers supplies, durable medical equipment, drugs and services not in CPT. NDC codes identify specific drug products. A clean claim requires the diagnosis to support medical necessity for the procedure.

Answer: A
Payers require that the reported diagnosis justify the service, which is the medical necessity linkage. A mismatch produces a denial that is corrected by verifying documentation and resubmitting with the appropriate codes. Deductible status and network participation affect patient responsibility and allowed amounts, not the necessity determination.

Answer: A
The deductible is satisfied first: until the patient has paid 500 dollars out of pocket, the full allowed amount is the patient's responsibility. Coinsurance applies only after the deductible is met, at which point the patient pays 20 percent and the plan pays 80 percent of the allowed amount.

Answer: A
A copayment is a flat amount collected at the time of service, often at the front desk. Coinsurance is a percentage share of the allowed amount calculated after the claim is adjudicated, so it is typically billed later. Both differ from the deductible, which is the amount a patient pays before the plan begins sharing costs.

Answer: A
Eligibility verification confirms the policy is active, identifies the plan's requirements such as referral or prior authorization, and establishes copay, deductible and coinsurance so the patient can be told what they will owe. It does not guarantee payment, because coverage still depends on medical necessity and correct claim submission.

Answer: A
Prior authorization is the payer's advance approval that a planned service meets coverage criteria. Assignment of benefits directs the payer to pay the provider directly. Coordination of benefits determines payment order when a patient has more than one plan, and an explanation of benefits is the statement issued after adjudication.

Answer: A
Coordination of benefits establishes primary and secondary payers so total payment does not exceed the allowed charge. A patient's own employer plan is generally primary over a plan on which they are a dependent. Capitation is a per-member per-month payment model rather than a payment-order rule.

Answer: A
A participating provider agrees to accept the plan's allowed amount as payment in full, so the difference between the usual charge and the allowed amount is adjusted off. Billing the patient for it is balance billing and violates the contract. The patient remains responsible for deductible, copay and coinsurance.

Answer: A
Alphabetic filing compares unit by unit, letter by letter, with nothing before something: Adams ends after five letters, so it precedes Adamsen, Adamski and Adamson. The subsequent order is determined at the sixth character, where e precedes i, which precedes o. Given names are used only when surnames are identical.

Answer: D
Unbundling separates services that a comprehensive code already includes so each piece is billed individually, inflating payment — an abusive practice payers detect with claim edits. Bundling is the correct opposite, combining components into one code; balance billing charges patients the difference above allowed amounts; and coordination of benefits sequences multiple insurance plans.

Answer: D
Medicaid pays only after all other coverage has adjudicated, which is why it is called the payer of last resort; the commercial plan is billed first and Medicaid considers any remaining balance. Billing both at once for the full charge invites overpayment and recoupment, and patients cannot waive the mandated payer order at will.

Answer: D
The matrix is the framework of the appointment book: times when providers are unavailable are crossed off first so patients are only booked into genuinely open slots. Wave describes a method of distributing patient arrivals, a tickler file tracks future follow-up tasks, and a problem list is a clinical record component, not a scheduling tool.

Answer: B
Modified wave brings a small group in at the start of the hour and reserves the back half of the hour as buffer, smoothing out late arrivals and variable visit lengths. Stream scheduling assigns each patient an individual fixed time, open hours lets patients arrive at will during posted periods, and advanced access focuses on same-day availability rather than hourly grouping.

Answer: D
Double booking deliberately places two patients in one time slot and works when their needs draw on different resources, such as a nurse-only recheck alongside a provider visit. Cluster scheduling groups similar appointment types into blocks, stream assigns each patient a unique time, and open booking has no fixed appointment times at all.

Answer: B
Missed appointments are documented in the chart because a pattern of no-shows can matter clinically and legally, especially if the patient later alleges lack of follow-up; office policy then governs reminder calls or letters. Deleting the entry destroys the record, discharge after a single miss is disproportionate, and insurers are not billed for services never rendered.

Answer: A
Cluster scheduling groups appointments of the same type into dedicated blocks, which streamlines room setup, supplies, and staff workflow for repetitive visit types like well-child checks. Double booking overlaps two patients in one slot, wave brings several patients in at the start of an hour, and stream spaces individual appointments at fixed intervals throughout the day.

Answer: C
A consultation is a request for another provider's opinion or advice, after which the patient's management returns to the requesting provider, and documentation flows back in a consult report. A transfer would shift ongoing responsibility permanently, locum tenens is a substitute provider covering a practice, and concurrent care describes two providers actively co-managing simultaneously.

Answer: A
Chest pain with dyspnea is a potential myocardial infarction, and the office standard is to direct the caller to emergency services without delay under the practice's written triage protocol. Offering an antacid is giving medical advice outside the assistant's scope, and delay through scheduling or holding can be fatal.

Answer: A
Documentation records objective observations and the patient's own words in quotation marks, without opinion, judgment or diagnosis. Characterizing a patient as exaggerating is a subjective judgment that can damage both care and the record's credibility, and offering a diagnosis exceeds the medical assistant's scope.

Answer: A
Qualified interpreters protect accuracy and confidentiality and are required for meaningful access in federally funded settings. Using family members, particularly minors, risks mistranslation, omission of sensitive information and inappropriate burden. Volume does not overcome a language barrier, and untranslated materials do not convey instructions.

Answer: A
Closed questions produce short factual answers and are efficient for confirming specifics such as allergies or medication doses. Open-ended questions invite narrative and surface information a checklist would miss. Restating is reflection or paraphrasing, and premature reassurance is a communication barrier that closes down disclosure.

Answer: C
Acknowledging emotion and tolerating silence communicates presence and invites the patient to continue. Changing the subject and offering clichéd reassurance are recognized communication barriers that signal the topic is unwelcome. Raising scheduling pressure at that moment tells the patient their distress is an inconvenience.

Answer: D
Confidentiality extends to where conversations occur, not only to what is said. Waiting rooms, elevators and hallways are frequent sources of inadvertent disclosure. Social media posts about encounters risk re-identification even when details are altered, and accessing a coworker's record without a treatment relationship is a privacy violation regardless of motive.

Answer: A
Interpreting results and making a diagnosis are provider functions. A medical assistant may relay results the provider has reviewed and released, along with the provider's instructions, but may not explain clinical significance. Offering reassurance about an uninterpreted result is both outside scope and potentially false.

Answer: A
Gowning and draping with exposure limited to the area under examination is the standard for preserving dignity, along with explaining what will happen and ensuring privacy during undressing. An open door or unnecessary exposure violates that expectation, and clothing that obstructs the examination defeats the visit's purpose.

Answer: A
Any ambiguity in an order is resolved by asking the ordering provider directly, before acting. Guessing which source is authoritative, in either direction, risks administering the wrong care, and a colleague cannot resolve what the provider intended. Clarification is documented once obtained.

Answer: B
Insulin is secreted by the beta cells of the pancreatic islets and moves glucose from the blood into cells. The liver stores and releases glucose but does not make insulin, the thyroid regulates metabolic rate through thyroid hormones, and the adrenals produce cortisol and catecholamines — hormones that actually raise blood glucose rather than lower it.

Answer: B
Antipyretics, such as acetaminophen and ibuprofen, lower elevated body temperature. The word combines 'anti-' meaning against with 'pyret-' referring to fever. Drugs that thin secretions are expectorants or mucolytics, seizure-preventing agents are anticonvulsants, and appetite stimulants form yet another class — decoding drug-class terminology prevents documentation and teaching errors.

Answer: D
Hand hygiene is the single most effective measure to prevent health care associated infection. Gloves are not a substitute, because hands can be contaminated during removal and gloves can have unseen defects, and gloves must be changed between patients without exception. Surfaces are disinfected between patients, not only at closing.

Answer: B
Sterilization destroys all microbial life including spores and is required for instruments that penetrate tissue, typically achieved by autoclave. Disinfection kills most pathogens on inanimate surfaces but not reliably spores, sanitization reduces microbial counts to safe levels, and antisepsis inhibits microorganisms on living tissue.

Answer: A
Immediate washing and prompt reporting are required so that source testing and any post-exposure prophylaxis can begin within the effective window, which is time sensitive. Delay defeats the purpose. Squeezing the wound is not recommended, and exposure follow-up proceeds regardless of what is known about the source.

Answer: A
The Bloodborne Pathogens Standard requires an exposure control plan, hepatitis B vaccination offered at no cost, engineering and work practice controls including sharps disposal, personal protective equipment, labeling and training. The Hazard Communication Standard governs chemical hazards and requires safety data sheets and container labeling.

Answer: A
Sharps go directly into a labeled puncture-resistant container at the point of use, and recapping is prohibited because it is a leading cause of needlestick injury. Sharps containers are replaced before they are full. A biohazard bag is for contaminated soft waste and provides no puncture protection.
