Q1A 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?
Show answer
✓ Correct 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.
Q2During 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?
Show answer
✓ Correct 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.
Q3Which of the following pulse sites is most commonly used for routine vital sign measurement in an adult patient?
Show answer
✓ Correct 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.
Q4A 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?
Show answer
✓ Correct 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.
Q5When 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?
Show answer
✓ Correct 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.
Q6Which of the following oxygen saturation (SpO2) values would be considered within normal limits for a healthy adult at rest breathing room air?
Show answer
✓ Correct 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.
