Answer to Question 1

Correct Answer: 1,2
Rationale 1: Antihistamines can cause insomnia in children.
Rationale 2: Antihistamines can cause nervousness in children.
Rationale 3: Symptoms of dizziness are more common in older adults.
Rationale 4: Symptoms of confusion are more common in older adults.
Rationale 5: Symptoms of urinary hesitancy may occur in older adults with prostate enlargement.
Global Rationale: Antihistamines may cause paradoxical excitement, such as restlessness or nervousness, or insomnia especially in children. Symptoms of dizziness, confusion, and urinary hesitancy are more common in older adults.

Answer to Question 2

Correct Answer: 1,2,3
Rationale 1: Excess gastric acid production can be reduced by blocking H2 receptors.
Rationale 2: Symptoms of peptic ulcer disease are decreased when H2 receptors are blocked.
Rationale 3: When H2 receptors are blocked, gastric acid secretion is reduced, decreasing the symptoms of GERD.
Rationale 4: The symptoms of allergic rhinitis are the result of the activation of H1 receptors.
Rationale 5: The symptoms of seasonal allergies are the result of the activation of H1 receptors.
Global Rationale: Drugs that block H2 receptors such as ranitidine (Zantac) reduce gastric acid secretion and are used to treat peptic ulcer disease and gastroesophageal reflux disease. This histamine receptor activity is not related to allergic responses.
