Which of the following formulas should a medical assistant use to determine a patient's pulse rate?
Take the patient's pulse for 5 seconds and multiply by 10.
Take the patient's pulse for 15 seconds and multiply by 2.
Take the patient's pulse for 30 seconds and multiply by 4.
Take the patient's pulse for 30 seconds and multiply by 2.
The Correct Answer is D
A. Take the patient's pulse for 5 seconds and multiply by 10: Measuring for 5 seconds and multiplying by 10 is less accurate due to the short measurement time.
B. Take the patient's pulse for 15 seconds and multiply by 2: While this method is more accurate than taking it for 5 seconds, the recommended practice is to measure for 30 seconds for better accuracy.
C. Take the patient's pulse for 30 seconds and multiply by 4: This would be used to determine a pulse rate per minute from a 15-second measurement, not 30 seconds.
D. Take the patient's pulse for 30 seconds and multiply by 2: This method provides a precise measurement of the pulse rate, as taking the pulse for 30 seconds and then multiplying by 2 gives the number of beats per minute.

Correct Answer is B
Explanation
A. Place a pulse oximeter on the patient's earlobe: A pulse oximeter measures oxygen saturation and pulse but is not used for manually palpating the pulse.
B. Palpate the patient's radial artery: The radial artery, located at the wrist, is commonly palpated to manually obtain the pulse.
C. Place a pulse oximeter on the patient's finger: A pulse oximeter measures pulse rate and oxygen saturation but does not involve manual palpation.
D. Palpate the patient's popliteal artery: The popliteal artery is located behind the knee and is less commonly used for routine pulse measurement compared to the radial artery.
Correct Answer is C
Explanation
A. Gluteus maximus: The gluteus maximus is not a commonly used site for body fat measurement.
B. Biceps: The biceps are not typically used for body fat measurement. Measurements are usually taken at sites with more subcutaneous fat.
C. Infrailiac region: The infrailiac region, located just above the iliac crest (hip bone), is a common site for measuring body fat, along with other areas such as the triceps and subscapular region.
D. Triceps: While the triceps can be used for body fat measurement, the infrailiac region is another standard site used for accuracy in some methods.
