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.

Explanation
Choice A rationale: Alprazolam (Xanax) exerts its therapeutic effect by interacting with gamma-aminobutyric acid (GABA) receptors, leading to anxiolytic and sedative effects.
Choice B rationale: Norepinephrine is not the primary neurotransmitter affected by alprazolam.
Choice C rationale: Acetylcholine is not the primary neurotransmitter affected by alprazolam.
Choice D rationale: Serotonin (5-HT) is not the primary neurotransmitter affected by alprazolam.
Correct Answer is A
Explanation
Choice A rationale: Loss of consciousness is a serious adverse reaction that should be reported to the healthcare provider. Instructing the wife to call the provider if it happens again is an appropriate response.
Choice B rationale: Stopping the medication without consulting the provider may not be advisable, as sudden discontinuation of some medications can have adverse effects.
Choice C rationale: Taking the next dose with food may be a general recommendation for some medications, but it does not directly address the issue of loss of consciousness.
Choice D rationale: While moving slowly when changing positions is a general recommendation for some medications, the immediate concern is the loss of consciousness, and contacting the provider is more appropriate.
