A. Begin audiometer testing on the highest frequency and lower gradually: Audiometer testing should begin at lower frequencies and gradually increase to ensure a thorough evaluation of hearing.

Correct Answer is A
Explanation
A. Deflate the cuff slowly until the last sound is heard. The diastolic reading is determined when the last sound (Korotkoff sound) is heard as the cuff is deflated.
B. Listen for the first sound through the stethoscope: The first sound corresponds to the systolic reading, not the diastolic.
C. Document the reading when the gauge needle jumps: The gauge needle jump is not a reliable indicator of blood pressure readings.
D. Inflate the cuff to at least 180 mm Hg, deflate the cuff slowly, and listen for the first sound: Inflating to 180 mm Hg is unnecessary and might cause discomfort; also, the first sound is the systolic reading, not the diastolic.
