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?
Photophobia
Diarrhea
Dry mouth
Increased blood pressure
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 A
Explanation
A. Tachycardia: Theophylline can cause tachycardia as a side effect due to its stimulant properties.
B. Constipation: While gastrointestinal effects can occur, constipation is not a common or significant adverse effect of theophylline.
C. Oliguria: Theophylline is more likely to cause diuresis rather than oliguria.
D. Drowsiness: Theophylline typically causes stimulation rather than sedation, leading to increased alertness rather than drowsiness.
Correct Answer is B
Explanation
A. Vomiting: While vomiting can occur during anaphylaxis, it is not the most immediately life-threatening symptom.
B. Stridor: Stridor indicates upper airway obstruction, which is a critical and life-threatening sign of anaphylaxis. This finding requires immediate intervention, such as administering epinephrine and ensuring airway patency.
C. Hypertension: Hypertension is not typically associated with anaphylaxis; instead, hypotension is more common due to vascular collapse.
D. Urticaria: Urticaria (hives) can occur in anaphylaxis, but it is not as urgent as stridor, which indicates a compromised airway.
