1. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

2. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

3. What is a priority problem for a child with severe edema caused by nephrotic syndrome?

• A. Risk for constipation
• B. Risk for skin breakdown
• C. Inability to regulate body temperature
• D. Consuming more calories or nutrients than the body requires

Correct answer: B

Rationale: In nephrotic syndrome, characterized by massive proteinuria, hypoalbuminemia, and edema, a child with severe edema is at high risk for skin breakdown. The priority concern is to prevent skin breakdown by cleaning skin surfaces and ensuring adequate separation with clothing to avoid irritation. The child with nephrotic syndrome is typically anorexic, making consuming more calories or nutrients than necessary not a concern. Risk for constipation and inability to regulate body temperature are not primary issues associated with edema caused by nephrotic syndrome.

4. When admitting a 64-year-old patient with acute pancreatitis, the healthcare provider should specifically inquire about a history of

• A. diabetes mellitus.
• B. high-protein diet.
• C. cigarette smoking.
• D. alcohol consumption.

Correct answer: D

Rationale: In patients with acute pancreatitis, alcohol consumption is a significant risk factor and one of the most common causes in the United States. It is crucial to assess alcohol intake as it plays a key role in the development of pancreatitis. While cigarette smoking, diabetes mellitus, and high-protein diets can contribute to various health issues, they are not directly associated with the development of acute pancreatitis.

5. Which of the following medications taken by the patient is least likely to cause urine discoloration?

• A. Sulfasalazine
• B. Levodopa
• C. Phenolphthalein
• D. Aspirin

Correct answer: D

Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.
