Nursing Elites

1. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacological action of this medication?

• A. To stimulate the pancreas to secrete insulin
• B. To slow the absorption of glucose in the intestine
• C. To increase reabsorption of water in the renal tubules
• D. To increase blood pressure

Correct answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin mimics the action of antidiuretic hormone (ADH) by increasing the reabsorption of water in the renal tubules. This leads to decreased urine output, helping to manage symptoms of diabetes insipidus, which is characterized by excessive thirst and urination. Choices A, B, and D are incorrect. Vasopressin does not stimulate the pancreas to secrete insulin, slow the absorption of glucose in the intestine, or directly increase blood pressure.

2. A client is prescribed digoxin and has a potassium level of 3.0 mEq/L. Which of the following actions should the nurse take?

• A. Administer digoxin without any modifications
• B. Administer the medication at a lower dose
• C. Monitor serum potassium levels
• D. Discontinue the medication if potassium levels rise

Correct answer: A

Rationale: A potassium level of 3.0 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity. In this case, the nurse should administer the digoxin without any modifications. Lowering the dose (Choice B) may not be necessary if the potassium level is not critically low. Monitoring serum potassium levels (Choice C) is important but should not delay the administration of digoxin. Discontinuing the medication (Choice D) is not the initial action to take unless the potassium levels become severely low and life-threatening.

3. A nurse in a clinic is caring for a patient who has a UTI. What prescription should the nurse verify with a provider?

• A. Ciprofloxacin
• B. Trimethoprim-sulfamethoxazole
• C. Oxybutynin
• D. Nitrofurantoin

Correct answer: C

Rationale: The correct answer is C: Oxybutynin. Oxybutynin is an anticholinergic used to treat overactive bladder, not a UTI. The nurse should verify this prescription because it may not be appropriate for a UTI. Choices A, B, and D are antibiotics commonly used in the treatment of UTIs. Ciprofloxacin, trimethoprim-sulfamethoxazole, and nitrofurantoin are more suitable choices for the treatment of a UTI compared to oxybutynin.

4. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

5. A nurse is teaching a client about dietary modifications for a low-sodium diet. Which of the following should the nurse include?

• A. Limit intake of processed foods
• B. Increase intake of fresh fruits and vegetables
• C. Use of accessory muscles
• D. Monitor for allergic reactions

Correct answer: A

Rationale: The correct answer is to limit intake of processed foods. Processed foods are often high in sodium, which goes against the goal of a low-sodium diet. Fresh fruits and vegetables are recommended for a low-sodium diet due to their natural low sodium content. The use of accessory muscles and monitoring for allergic reactions are not related to dietary modifications for a low-sodium diet.
