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.
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
Rationale for A: Monitoring blood glucose levels is important in septic patients as hyperglycemia can occur due to stress response, and insulin resistance may develop. However, it is not the most critical intervention for immediate stabilization.
Rationale for B: Maintaining strict intake and output is crucial for a patient in septic shock because fluid balance is a key component in managing shock. Accurate measurement of intake and output ensures appropriate fluid resuscitation, which is vital for maintaining blood pressure and organ perfusion.
Rationale for C: Keeping the head of the bed raised 45 degrees can help prevent aspiration, which is particularly important in patients who are at risk of gastrointestinal bleeding or those who are sedated. However, this is not the primary intervention for septic shock management.
Rationale for D: Assessing the warmth of extremities can provide information about peripheral circulation and may indicate the effectiveness of cardiac output. Nevertheless, it is not the most immediate concern in the management of septic shock.
Correct Answer is A
Explanation
A. Keep diabetic medication on schedule as prescribed.
This is the correct answer because maintaining a regular schedule for diabetic medication is crucial for managing blood glucose levels and preventing complications.
B. Limit maximum daily fat intake to 15% of total calories.
While reducing fat intake can be beneficial for overall health, it is not directly related to managing acute blood glucose levels or preventing immediate complications of diabetes.
C. Check blood sugar levels every four to six hours every day.
Frequent monitoring of blood sugar levels is important, but checking every four to six hours may not be necessary for all clients, especially if they are not on insulin or if their diabetes is well-controlled. It depends on individual needs and physician recommendations.
D. Restrict alcoholic beverages to no more than 1-2 per week.
Limiting alcohol intake is good advice for overall health and diabetes management, but it is not the most critical action compared to keeping medications on schedule to prevent complications.
