Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: When a medical assistant misses the systolic reading, it is essential to ensure an accurate measurement. Waiting 1 to 2 minutes (Option C) allows the blood flow to return to normal after the first attempt, reducing the risk of falsely elevated or lowered readings due to residual pressure from the cuff.

Option A, repeating only the systolic measurement, is inadequate because it does not account for potential inaccuracies in diastolic readings. Option B, waiting only 5 to 30 seconds, may not provide enough time for accurate measurement, especially if the patient is anxious or if the cuff has caused temporary changes in circulation. Option D, not repeating the measurement, neglects the importance of obtaining a complete and accurate blood pressure reading, which is crucial for patient assessment and care.
