. A nurse is caring for a client who is prescribed diphenhydramine to relieve pruritus. The client asks the nurse how he can minimize the daytime sedation he is experiencing. Which of the following responses should the nurse give?
"Gradually decrease the dose once tolerance to the effect is reached."
"Take the medication with men is."
"Distribute the doses evenly throughout the day.”
"Take the daily dose at bedtime.”
The Correct Answer is D
A. "Gradually decrease the dose once tolerance to the effect is reached." Tolerance can develop over time, but this approach is not the most effective or safest way to manage sedation.
B. "Take the medication with meals." Taking diphenhydramine with food may help with gastrointestinal side effects but does not reduce sedation.
C. "Distribute the doses evenly throughout the day." Distributing doses evenly may not effectively reduce sedation, as diphenhydramine has sedative effects regardless of timing.
D. "Take the daily dose at bedtime.” Taking diphenhydramine at bedtime can minimize daytime sedation, as the sedative effects will occur during sleep.

Correct Answer is B
Explanation
A. The patient is hypertensive. Hypertension is not a prerequisite for starting BPH medication; in fact, some BPH medications can lower blood pressure.
B. The patient has had a prostate examination, including measurement of the PSA level. A prostate examination and PSA measurement are important for diagnosing BPH and ruling out prostate cancer before starting treatment.
C. The patient is still sexually active. Sexual activity status is not a determining factor for administering BPH medication.
D. The patient has not had a vasectomy. Vasectomy status does not influence the treatment of BPH.
Correct Answer is C
Explanation
A. Photophobia: Photophobia is not a common side effect of antihistamines. It can be associated with other conditions, but not typically with antihistamine use.
B. Diarrhea: Diarrhea is not a common side effect of antihistamines; they are more likely to cause constipation due to their anticholinergic effects.
C. Dry mouth: Dry mouth is a common anticholinergic effect of antihistamines. It occurs because these medications block acetylcholine, leading to decreased saliva production.
D. Increased blood pressure: Increased blood pressure is not a typical side effect of antihistamines. While some formulations may cause increased heart rate or palpitations, they do not generally lead to hypertension directly.
