Clinical Medical Assistant Exam Practice Question

Correct Answer: D

Rationale: To collect an accurate peak flow reading, the patient must exhale forcefully and rapidly into the peak flow meter. This approach ensures that the maximum airflow is measured, which is critical for assessing lung function.

Option A is incorrect because inhaling deeply does not provide a valid reading; the focus should be on exhalation. Option B is misleading, as normal breathing does not yield peak flow data; a strong exhalation is required. Option C is also wrong, as holding the breath before exhaling does not allow for the necessary forceful outflow needed for an accurate measurement.
