, Question 1
A medical assistant is preparing to perform a capillary puncture on a patient
who is receiving warfarin therapy. Which of the following collection sites is
most appropriate to minimize bleeding risk?
A. Central area of the fingertip
B. Lateral aspect of the third or fourth finger
C. Earlobe
D. Heel
Correct Answer: B - Lateral aspect of the third or fourth finger
RATIONALE
The lateral aspect of the third or fourth finger is preferred for capillary
puncture in adults because it has less nerve density and adequate blood
flow, reducing pain and bleeding risk. Warfarin increases bleeding
risk, so avoiding the central fingertip (which has more nerve endings
and vessels) is prudent. Earlobe and heel are not standard adult sites
and carry higher risk of complications.
Question 2
Which of the following best explains why a medical assistant should verify a
patient's insurance eligibility before a scheduled procedure?
A. To determine the patient's copayment amount
B. To confirm coverage and prevent claim denials
C. To update the patient's medical history
D. To schedule follow-up appointments
Correct Answer: B - To confirm coverage and prevent claim
denials

, RATIONALE
Verifying insurance eligibility ensures the procedure is covered under
the patient's plan, reducing the risk of claim denials and unexpected
costs. While copayment may be a factor, the primary purpose is
coverage confirmation. Updating medical history and scheduling are
separate administrative tasks not directly related to eligibility
verification.
Question 3
A patient's EKG shows a prolonged PR interval (>200 ms) with a consistent
1:1 P-to-QRS ratio. Which of the following conditions is most consistent with
this finding?
A. First-degree AV block
B. Second-degree AV block, Mobitz I
C. Second-degree AV block, Mobitz II
D. Third-degree AV block
Correct Answer: A - First-degree AV block
RATIONALE
A prolonged PR interval (>200 ms) with every P wave followed by a
QRS complex indicates first-degree AV block. Mobitz I shows
progressive PR prolongation until a dropped beat; Mobitz II has
constant PR with intermittent dropped beats; third-degree shows no
relationship between P and QRS. The consistent 1:1 ratio rules out
higher-degree blocks.
Question 4
A medical assistant is calculating a pediatric dose. The order is for 15
mg/kg/day divided every 8 hours. The patient weighs 22 lb. How many mg
should be administered per dose?
A. 50 mg
B. 75 mg
Page 3
, C. 100 mg
D. 150 mg
Correct Answer: A - 50 mg
RATIONALE
Convert weight: 22 lb ÷ 2.2 = 10 kg. Total daily dose = 15 mg/kg × 10
kg = 150 mg/day. Divided every 8 hours = 3 doses/day, so 150 ÷ 3 =
50 mg per dose. Options B, C, and D result from calculation errors
(e.g., failing to convert lb to kg or dividing incorrectly).
Question 5
Which of the following is the most appropriate action when a medical assistant
witnesses a coworker failing to perform hand hygiene between patient
contacts?
A. Ignore the behavior to avoid conflict
B. Report the incident to the supervisor immediately
C. Confront the coworker in front of the patient
D. Document the event in the patient's chart
Correct Answer: B - Report the incident to the supervisor
immediately
RATIONALE
Failure to perform hand hygiene is a breach of infection control
standards and poses a patient safety risk. The appropriate action is to
report to a supervisor per facility policy, ensuring patient safety and
accountability. Ignoring it, confronting publicly, or charting it in the
patient's record are inappropriate and unprofessional.
Question 6
A medical assistant is explaining a low-sodium diet to a patient with
hypertension. Which of the following statements by the patient indicates a need
for further teaching?
