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.

A. "Use the peak expiratory flow meter once per week." B. "Take cromolyn sodium at the first sign of breathing difficulty." C. "Avoid triggers that cause an attack." D. "You should stop playing basketball, but you can swim instead."

Correct Answer is C

Explanation

A. "Use the peak expiratory flow meter once per week." The peak expiratory flow meter is usually recommended for daily use in asthma management to monitor lung function and detect any changes early.

B. "Take cromolyn sodium at the first sign of breathing difficulty." Cromolyn sodium is a mast cell stabilizer and is used as a preventative medication rather than for quick relief of symptoms, so it should be taken regularly as prescribed, not only when symptoms arise.

C. "Avoid triggers that cause an attack." Avoiding known asthma triggers is an important part of asthma management to prevent attacks and exacerbations.

D. "You should stop playing basketball, but you can swim instead." Exercise should not necessarily be avoided; instead, it should be managed appropriately with pre-treatment if needed. Avoiding all sports activities is not generally recommended.
