A.

Bradycardia.

B.

Hypertension

C.

Bleeding

D.

Sedation

Answer and Explanation

The Correct Answer is D

A. Bradycardia: Bradycardia is not a common side effect of diphenhydramine. This medication primarily causes sedation and anticholinergic effects.

 

B. Hypertension: Hypertension is not commonly associated with diphenhydramine, which tends to have more sedative and anticholinergic side effects.

 

C. Bleeding: Bleeding is not a known side effect of diphenhydramine. It does not affect clotting mechanisms or platelet function.

 

D. Sedation: Sedation is a common side effect of diphenhydramine, which is an antihistamine with sedative properties. Clients should be advised about possible drowsiness and to avoid activities that require alertness, like driving, while taking it.

Correct Answer is A

Explanation

A. Daily or weekly weight: Daily or weekly weight measurements are a reliable way to assess fluid retention. A sudden increase in weight can indicate fluid overload.

B. Sodium level: While sodium levels can provide some information about fluid balance, they are not as direct or reliable as weight measurements for assessing fluid retention.

C. Tissue turgor: Tissue turgor can give some insight into hydration status but is subjective and less reliable compared to weight measurements, especially in clients with chronic conditions.

D. Intake and output: While monitoring intake and output is important for assessing fluid balance, it may not accurately reflect fluid retention, as it doesn't account for fluid shifts or loss through other routes.

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.
