The nurse is preparing to administer a histamine 2-receptor antagonist to a client with peptic ulcer disease. What is the primary purpose of this drug classification?

Neutralizes hydrochloric acid (HCI) in the stomach.

Inhibits action of acetylcholine by blocking parasympathetic nerve endings.

Destroys microorganisms causing stomach inflammation.

Decreases the amount of HCI secretion by the parietal cells in the stomach.

Answer and Explanation

The Correct Answer is D

A. Histamine 2-receptor antagonists do not directly neutralize hydrochloric acid (HCl) in the stomach. Instead, they reduce acid secretion by blocking the histamine 2 receptors on parietal cells, thereby decreasing the production of gastric acid.

B. This describes the mechanism of action of anticholinergic medications, not histamine 2- receptor antagonists.

C. Histamine 2-receptor antagonists do not have antimicrobial properties and are not used to destroy microorganisms causing stomach inflammation. They primarily target acid secretion.

D. This is the correct purpose of histamine 2-receptor antagonists. They work by blocking the action of histamine on parietal cells in the stomach, leading to a reduction in the secretion of hydrochloric acid. This helps in the management of peptic ulcer disease and other conditions related to excessive gastric acid secretion.

Correct Answer is C

Explanation

A. Aching leg. Aching leg is not a commonly occurring problem after gastric endoscopy. It may be related to positioning during the procedure or another unrelated issue.
B. Nausea. Nausea is a potential side effect of the anesthesia or sedation used during the procedure. However, it is not as commonly occurring as a sore throat after gastric endoscopy.
C. Sore throat. Sore throat is a commonly occurring problem after gastric endoscopy due to

irritation of the throat by the endoscope. It is often caused by the insertion and manipulation of the scope during the procedure.
D. Headache. While headache can occur as a side effect of anesthesia or sedation, it is not as commonly associated with gastric endoscopy as a sore throat.

A. Do not take any over-the-counter medications. B. Eat a high carbohydrate, low fat, low protein diet. C. Call the crisis hot line if feeling lonely. D. Avoid exposure to large crowds.

Correct Answer is A

Explanation

A. Do not take any over-the-counter medications. This is crucial because many over-the-counter medications, including those containing acetaminophen, can further damage the liver. Avoiding these medications is essential to prevent further hepatic injury.
B. Eat a high carbohydrate, low fat, low protein diet. While diet can influence liver health, this specific dietary advice is less critical than preventing further liver damage from medications.
C. Call the crisis hot line if feeling lonely. This is important for mental health support, but the immediate physical health concern related to liver damage takes precedence.
D. Avoid exposure to large crowds. This may be relevant if the client is immunocompromised due to liver damage, but it is not as directly related to preventing further liver injury as avoiding certain medications.
