Medical Assistant Exam Questions & Answers 2026 (1–10)

Question 1

A medical assistant is preparing to collect a mid-stream clean-catch urine specimen from a female patient. After the patient cleanses the perineal area, which of the following instructions is correct?

TheoryPractice · Accepted Answer

Void a small amount into the toilet, then collect the mid-stream portion in the cup, then finish voiding into the toilet. A mid-stream clean-catch specimen requires discarding the initial urine stream to flush urethral contaminants, then collecting the midstream portion, which reduces the risk of specimen contamination with periurethral flora.

Question 2

During auscultation of blood pressure, the medical assistant hears the first Korotkoff sound at 128 mmHg and the sounds completely disappear at 76 mmHg. However, there is a silent gap (auscultatory gap) between 110 and 90 mmHg. If only the disappearance of sound is used without recognizing the gap, what erroneous reading would be documented?

TheoryPractice · Accepted Answer

90/76 mmHg — systolic is falsely low because the gap was mistaken for silence. An auscultatory gap is a period of silence in the middle of Korotkoff sounds; if the cuff is not inflated high enough to pass above the true systolic pressure, the MA may begin listening after the gap, mistaking the resumption of sounds at 90 mmHg for the systolic pressure, yielding a falsely low systolic reading.

Question 3

Which of the following pulse sites is most commonly used for routine vital sign measurement in an adult patient?

TheoryPractice · Accepted Answer

Radial. The radial artery at the wrist is the standard site for routine adult pulse measurement because it is superficial, easily palpable, and accessible without disturbing the patient.

Question 4

A patient scheduled for a fasting lipid panel arrives and reports eating a handful of crackers two hours ago. What is the most appropriate action by the medical assistant?

TheoryPractice · Accepted Answer

Notify the provider and reschedule the draw so the patient can complete the full required fast. A standard fasting lipid panel requires 9–12 hours of fasting; any food intake invalidates the fast, so the appropriate action is to inform the provider and reschedule rather than draw an invalid specimen.

Question 5

When preparing a patient for a 12-lead electrocardiogram (ECG), the medical assistant notices the patient is wearing a transdermal nitroglycerin patch on the left chest. What is the correct action?

TheoryPractice · Accepted Answer

Remove the patch, cleanse the skin, and place the electrode on clean skin, then notify the provider. Transdermal patches must be removed before electrode placement because they interfere with electrical conduction and adhesion; the provider must be notified because removing a medicated patch requires clinical awareness.

Question 6

Which of the following oxygen saturation (SpO2) values would be considered within normal limits for a healthy adult at rest breathing room air?

TheoryPractice · Accepted Answer

97%. Normal SpO2 for a healthy adult at rest is 95–100%; a reading of 97% falls squarely within the normal range, while values below 95% warrant clinical evaluation.

Question 7

A medical assistant accidentally sustains a needlestick from a used needle after drawing blood from a patient with unknown HIV status. After washing the wound, what is the NEXT immediate step per standard post-exposure protocol?

TheoryPractice · Accepted Answer

Report the exposure to the supervisor/employer and seek evaluation for post-exposure prophylaxis (PEP) without delay. OSHA Bloodborne Pathogen Standards and CDC guidelines require immediate reporting to the employer and prompt medical evaluation for PEP, ideally within 2 hours of exposure, because PEP efficacy decreases significantly with delay beyond 72 hours.

Question 8

A provider orders a wound culture from an infected laceration. The medical assistant should collect the specimen by swabbing which area of the wound to obtain the most clinically meaningful sample?

TheoryPractice · Accepted Answer

The center of the wound after removing surface debris and gently rotating the swab against viable tissue. A wound culture is most accurate when collected from viable, clean wound tissue after removing surface debris, because surface exudate often contains colonizing organisms that do not reflect the true infectious pathogen.

Question 9

Which patient position is most appropriate when preparing a patient for a routine gynecological pelvic examination?

TheoryPractice · Accepted Answer

Lithotomy. The lithotomy position, in which the patient lies supine with hips and knees flexed and feet supported in stirrups, provides optimal visualization and access for pelvic and gynecological examinations.

Question 10

A medical assistant is performing a capillary blood glucose test using a glucometer. The control solution result falls outside the acceptable range printed on the test strip vial. What is the correct course of action?

TheoryPractice · Accepted Answer

Test another control solution from a different vial; if it also fails, take the glucometer out of service and notify the supervisor before testing any patients. Quality control guidelines for point-of-care testing require that a failed QC result triggers troubleshooting (new control, new strip lot, different device), and the instrument must be removed from patient use until the problem is identified and resolved to ensure result accuracy.
