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 C
Explanation
A. Friction rub: A friction rub is usually associated with pleuritis, not atelectasis. Atelectasis involves the collapse of alveoli and does not produce this sound.
B. Decreasing respiratory rate: Atelectasis generally leads to an increased respiratory rate as the body compensates for decreased oxygenation.
C. Increasing dyspnea: Increasing dyspnea is common in atelectasis as collapsed alveoli reduce oxygen exchange, leading to shortness of breath and increased respiratory effort.
D. Facial flushing: Facial flushing is not typically associated with atelectasis; instead, atelectasis leads to signs of respiratory distress, such as dyspnea and possibly cyanosis.
Correct Answer is D
Explanation
A. Narrowed pulse pressure: A narrowed pulse pressure can indicate various cardiovascular issues but is not a specific sign of pneumonia.
