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.
