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 A

Explanation

A. The neck is the correct location for auscultating a carotid bruit. A carotid bruit is an abnormal sound heard over the carotid artery in the neck, typically indicative of turbulent blood flow due to a narrowing or blockage in the artery.

B. Auscultating the femoral region would not yield information about carotid bruits. The femoral region pertains to the upper thigh area and is not anatomically related to the carotid artery.

C. The cubital fossa is the inner elbow region and is not associated with auscultation for carotid bruits. It is typically used for auscultation of blood pressure using the brachial artery.

D. The navel (belly button) is not a relevant location for auscultation for carotid bruits. It is far from the carotid arteries and would not provide any meaningful information about carotid artery sounds.

A. Provide only distilled water. B. Document abdominal girth. C. Offer a high protein diet. D. Use a cushion when sitting.

Correct Answer is B

Explanation

A. Provide only distilled water. Providing only distilled water is not appropriate in this situation.
The client's weight gain and electrolyte imbalance indicate the need for careful monitoring and intervention, but restricting fluid intake to distilled water alone may not address the underlying issues adequately.
B. Document abdominal girth. Documenting abdominal girth is important to assess for signs of ascites, which can occur in hepatic failure. A sudden weight gain and elevated blood pressure may indicate fluid retention, and documenting abdominal girth can provide additional information about fluid accumulation in the abdomen.
C. Offer a high protein diet. While nutritional support is important for clients with hepatic failure, offering a high protein diet may not be appropriate if the client has an electrolyte imbalance. Protein intake should be balanced and monitored carefully to avoid exacerbating the imbalance.
D. Use a cushion when sitting. Using a cushion when sitting may be beneficial for comfort, but it does not directly address the identified issues of electrolyte imbalance, elevated blood pressure, and weight gain. The priority is to assess and address these concerns through appropriate
interventions such as documenting abdominal girth and addressing fluid retention.
