A patient is receiving Prazosin, a drug that blocks alpha1-adrenergic receptors. Which adverse effect, if experienced by the patient, is of most concern to the nurse?
Nasal congestion
Orthostatic hypotension
Inhibition of ejaculation
Reflex tachycardia
The Correct Answer is B
Choice A rationale: Nasal congestion is a common side effect of alpha1-adrenergic blockers, not a cause for concern.
Choice B rationale: Orthostatic hypotension is a potential adverse effect of alpha1- adrenergic blockers like prazosin. It can lead to dizziness and falls, particularly when moving from a lying or sitting position to a standing one.
Choice C rationale: Inhibition of ejaculation is a potential side effect of alpha1- adrenergic blockers but is not of the most concern compared to orthostatic hypotension.
Choice D rationale: Reflex tachycardia is not a typical adverse effect of alpha1- adrenergic blockers.

Correct Answer is A
Explanation
Choice A rationale: Patient-controlled analgesia (PCA) devices provide a controlled dose of medication when the patient presses the button. However, the onset of action for morphine is typically faster than 10 minutes.
Choice B rationale: PCA devices often have a lock-out period to prevent patients from administering too many doses too quickly and risking overdose.
Choice C rationale: Patient-controlled analgesia is designed for the patient to self- administer the medication. Allowing family members to press the button may lead to inaccurate dosing.
Choice D rationale: Morphine should be administered as needed, not preemptively.
Administering the medication 10 minutes before physical therapy could result in excessive sedation.
