A medical assistant is preparing to fax a prescription to a patient's pharmacy. The assistant should identify that the provider's directions for the patient are in which area of the prescription?

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.

A. Ischemia: Ischemia refers to the lack of blood flow to tissues, which can lead to tissue damage or death, but it is not related to swelling due to fluid accumulation.
B. Edema: Edema is the correct term for tissue swelling caused by the accumulation of interstitial fluids, making this the correct choice.
C. Infarction: Infarction refers to tissue death due to a lack of blood supply, not to swelling caused by fluid accumulation.
D. Gangrene: Gangrene is the death of body tissue due to a lack of blood flow or severe infection, not related to fluid accumulation and swelling.
