A nurse is assessing a client who has seasonal allergies and is taking an antihistamine. Which of the following findings is an adverse effect of this type of medication?

A.

Photophobia

B.

Diarrhea

C.

Dry mouth

D.

Increased blood pressure

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is D

Explanation

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 C

Explanation

A. Urine-specific gravity: While urine-specific gravity can provide information on kidney function, it does not specifically measure renal impairment or disease progression, especially in SLE.

B. Serum potassium: Serum potassium levels can be affected by renal function but are not a direct indicator of renal health and can be influenced by many other factors.

C. Serum creatinine: Serum creatinine is a more reliable indicator of renal function, as it reflects how well the kidneys are filtering waste. In clients with SLE, kidney involvement is a common complication.

D. Serum sodium: Serum sodium levels do not directly indicate renal function, though kidney impairment can impact electrolyte levels.
