B. LL on the soft tissue of the leg.

C. RL on the soft tissue of the leg.

D. LL on the muscular portion of the leg.

Your response:
RL on the soft tissue of the leg.
Correct response:
RL on the soft tissue of the leg.
Rationale: When performing an ECG, the RL ground lead should be positioned on the soft tissue
of the right leg.
Forced Vital Capacity is measured by instructing the patient to

A. forcefully breath air out and continue to exhale for at least 6 seconds.

B. complete a minimum of eight acceptable efforts to validate the test.

C. move the one way valve to a minimum of 4000 ml capacity.

D. exhale as fast and hard as possible and document the reading.

Your response:
forcefully breath air out and continue to exhale for at least 6 seconds.
Correct response:
forcefully breath air out and continue to exhale for at least 6 seconds.
Rationale: Respiratory tests are performed to assess and/or monitor lung function. A spirometer
measures how fast and how much air is pushed/forced out of the lungs. Forced Vital Capacity
(FVC) is measured by instructing the patient to forcefully breath air out and continue to exhale
for at least 6 seconds. When doing spirometry testing, the total attempts should be limited to 8,
not a minimum of 8. The one way valve should not be moved to 4000 mL capacity. A patient
should blow out as hard and fast for as long as possible, and 3 acceptable attempts are
documented to ensure test validity (not just the highest reading).
The physician has instructed the medical assistant to obtain a patient’s temperature. Before
placing the oral thermometer in the patient's mouth, it is important to ensure the accuracy of the
reading by asking the patient if she has

A. recently ingested hot or cold food or beverages.

B. taken her prescribed medications today.

C. had a fever in the last 24 hours.

D. pain with swallowing.
