, Question 1
A provider orders 0.5 g of a medication. The pharmacy supplies a 250 mg/5
mL suspension. Which volume should the medical assistant administer?
A. 5 mL
B. 10 mL
C. 2.5 mL
D. 20 mL
Correct Answer: B - 10 mL
RATIONALE
Convert 0.5 g to 500 mg. Using the ratio 250 mg/5 mL, set up: (500
mg / 250 mg) × 5 mL = 10 mL. Options A, C, and D result from
incorrect conversion or ratio inversion, common errors in dosage
calculations.
Question 2
Which action best prevents transmission of multidrug-resistant organisms
(MDROs) during a dressing change?
A. Wearing gloves and a gown only when visibly soiled
B. Performing hand hygiene before and after donning gloves
C. Using alcohol-based hand rub after removing gloves without washing
D. Placing the patient in a negative-pressure room
Correct Answer: B - Performing hand hygiene before and after
donning gloves
RATIONALE
Hand hygiene before and after glove use is the cornerstone of MDRO
prevention. Gloves alone do not prevent transmission if hand hygiene
is omitted. Negative-pressure rooms are for airborne precautions, not
standard MDRO contact precautions.

, Question 3
A patient's spirometry results show a reduced FEV1/FVC ratio that improves
significantly after bronchodilator administration. This pattern is most
consistent with:
A. Restrictive lung disease
B. Asthma
C. Chronic obstructive pulmonary disease (COPD)
D. Pulmonary fibrosis
Correct Answer: B - Asthma
RATIONALE
A reduced FEV1/FVC ratio with significant reversibility after
bronchodilator is characteristic of asthma. COPD also shows
obstruction but with incomplete reversibility. Restrictive diseases and
fibrosis typically show a normal or increased ratio.
Question 4
Which of the following best describes the principle of 'informed consent' in a
medical assisting context?
A. The patient signs a form without asking questions.
B. The provider explains risks and benefits, and the patient voluntarily
agrees.
C. The medical assistant witnesses the signature only.
D. Consent is implied for all routine procedures.
Correct Answer: B - The provider explains risks and benefits, and
the patient voluntarily agrees.
Page 3
, RATIONALE
Informed consent requires the provider to disclose risks, benefits, and
alternatives, and the patient must voluntarily agree. The medical
assistant's role is to witness or obtain signature, not to explain. Implied
consent applies only in emergencies.
Question 5
A patient with a history of latex allergy requires a blood draw. Which
precaution is most appropriate?
A. Use latex-free gloves and tourniquet.
B. Double-glove with latex gloves.
C. Apply a cloth tourniquet over latex gloves.
D. Proceed with standard latex gloves but wash hands immediately after.
Correct Answer: A - Use latex-free gloves and tourniquet.
RATIONALE
Latex allergy requires strict avoidance of all latex-containing items,
including gloves and tourniquets. Double-gloving with latex increases
exposure. Washing after does not prevent reaction. Latex-free supplies
are essential.
Question 6
Which of the following is the most appropriate first action when a patient
becomes unresponsive and pulseless in the clinic?
A. Check for a pulse for 10 seconds.
B. Begin chest compressions immediately.
C. Retrieve the AED before starting compressions.
D. Administer epinephrine.
Correct Answer: B - Begin chest compressions immediately.
