A nurse is obtaining a medication history on a newly admitted patient, who reports taking minoxidil for hypertension. Admission vital signs reveal a heart rate of 78 beats per minute and a blood pressure of 120/80 mm Hg
What is an important part of the initial assessment for this patient?
a. Evaluating ankle edema
b. Monitoring for nausea and vomiting
c. Noting the presence of hypertrichosis
d. Obtaining a blood glucose
ANS: A
Fluid retention is a common and serious adverse effect of minoxidil, because it can lead to cardiac decompensation. If present, a diuretic is indicated. Nausea and vomiting may occur with this drug but is not a serious side effect. Hypertrichosis occurs in about 80% of patients taking the drug, but its effects are cosmetic and not life threatening. It may be important to monitor the blood glucose level in some patients, because the drug can alter glucose tolerance, but this effect is not as serious as fluid retention.
