A patient is receiving a drug that activates alpha1 receptors. Based on that mechanism of action, a nurse should assess for which of the following expected effects of the medication?
a. Mydriasis
b. Miosis
c. Hypertension
d. Decreased heart rate
ANS: A
An alpha1 response would result in mydriasis, or widening of the pupil, and would facilitate an eye exam.
Miosis describes pupillary constriction and is not a result of an alpha1-receptor response.
Hypertension is an adverse effect of alpha1 activation and therefore would not be an expected response.
A decreased heart rate would not be an expected response of an alpha1-receptor medication.
