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 B

Explanation

A. Initiating teaching for client care after discharge is incorrect. Teaching, especially initial or comprehensive education, is within the scope of practice of a registered nurse (RN), not a practical nurse (PN).
B. Using bladder ultrasound to detect urinary retention is correct. This is a task within the scope of practice for a PN, as it involves data collection and does not require independent clinical judgment.
C. Completing comprehensive assessments is incorrect. Comprehensive assessments require critical thinking and are the responsibility of the RN. PNs may collect data but do not perform initial comprehensive assessments.
D. Beginning initial sterile wound care for surgical clients is incorrect. The RN should perform the first sterile dressing change postoperatively to assess the wound properly. The PN may perform subsequent dressing changes per facility policy.

A. Resume antithyroid drug therapy. B. Anticipate and monitor for hypothermia. C. Prepare to administer radioactive iodine treatments. D. Maintain a semi-Fowler position.

Correct Answer is D

Explanation

A. Resume antithyroid drug therapy.
Antithyroid medications are typically not resumed immediately post-thyroidectomy unless specifically directed by the healthcare provider. The focus post-surgery is often on managing potential complications and ensuring proper healing.

B. Anticipate and monitor for hypothermia.
Hypothermia is not a common concern following thyroidectomy. The nurse should monitor for other more relevant complications such as bleeding, airway obstruction, and hypocalcemia.

C. Prepare to administer radioactive iodine treatments.
Radioactive iodine treatment is usually not administered immediately post-thyroidectomy. It may be considered later, depending on the reason for the thyroidectomy and the individual treatment plan.

D. Maintain a semi-Fowler position.
This is the correct intervention. Maintaining the client in a semi-Fowler position helps reduce strain on the surgical site, facilitates breathing, and minimizes the risk of complications such as bleeding and edema in the neck area. It is an essential part of postoperative care for
thyroidectomy patients.
