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. "Clean the perineal area from back to front.": For females, cleaning should be done from front to back to avoid contamination from fecal matter. For males, cleaning should be done around the urethral opening.
B. "Void a small amount into the toilet before voiding into the cup.": This helps to flush out any contaminants from the urethra, ensuring that the urine collected in the cup is as clean as possible.
C. "Urinate directly into the container with preservative.": Urinating directly into a container with preservative can contaminate the sample and is not recommended for a clean catch specimen.
D. "Collect all urine from start to finish.": The clean catch method specifically involves discarding the initial stream of urine and collecting the midstream to avoid contaminants.
Correct Answer is D
Explanation
A. Remove dental plates before the procedure. Dental plates do not interfere with a mammogram, so removing them is unnecessary.
B. Do not eat or drink anything for 4 hr before the procedure. There are no dietary restrictions required before a mammogram, so this instruction is not necessary.
C. An IV will be started before the procedure. An IV is not required for a mammogram, which is a non-invasive imaging procedure.
D. Do not apply any deodorant before the procedure. Patients are advised not to apply deodorant, lotions, or powders before a mammogram because these products can show up as artifacts on the mammogram images, potentially leading to misinterpretation.
