Nursing Elites

1. Potassium-sparing diuretics primarily affect which part of the kidney?

• A. Proximal convoluted tubule
• B. Loop of Henle
• C. Collecting duct
• D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

2. A client receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?

• A. Ondansetron
• B. Metoclopramide
• C. Promethazine
• D. Lorazepam

Correct answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

3. A client is prescribed Propranolol for a dysrhythmia. Which of the following actions should the nurse plan to take?

• A. Hold Propranolol if the client's apical pulse is greater than 100/min.
• B. Administer Propranolol to decrease the client's blood pressure.
• C. Assist the client with sitting up or standing after taking this medication.
• D. Monitor the client for hypokalemia due to the risk of Propranolol toxicity.

Correct answer: C

Rationale: The correct action the nurse should plan to take when administering Propranolol is to assist the client when sitting up or standing after taking the medication. Propranolol can lead to orthostatic hypotension, causing dizziness upon sudden position changes. It is essential to help the client with position changes to prevent falls or injury. Holding Propranolol if the client's apical pulse is greater than 100/min (Choice A) is incorrect because Propranolol is often used to manage dysrhythmias and slowing down the heart rate. Administering Propranolol to decrease the client's blood pressure (Choice B) is not the primary indication for using this medication. Monitoring the client for hypokalemia due to the risk of Propranolol toxicity (Choice D) is not a direct effect of Propranolol; rather, it is more related to other medications like diuretics.

4. A client has a new prescription for Digoxin for heart failure. Which of the following adverse effects should the client monitor for and report to the provider?

• A. Dry cough
• B. Pedal edema
• C. Bruising
• D. Yellow-tinged vision

Correct answer: D

Rationale: The correct answer is D: Yellow-tinged vision. Yellow-tinged vision is a potential adverse effect of Digoxin and may indicate toxicity. Clients should be instructed to report this symptom promptly to the healthcare provider to prevent complications. Dry cough (choice A) is not typically associated with Digoxin. Pedal edema (choice B) is more commonly seen with heart failure but is not a direct adverse effect of Digoxin. Bruising (choice C) is not a common adverse effect of Digoxin.

5. A nurse is assessing a client who is receiving IV vancomycin. The nurse notes a flushing of the neck and tachycardia. Which of the following actions should the nurse take?

• A. Document that the client experienced an anaphylactic reaction to the medication.
• B. Change the IV infusion site.
• C. Decrease the infusion rate on the IV.
• D. Apply cold compresses to the neck area.

Correct answer: C

Rationale: Flushing and tachycardia are signs of Red Man Syndrome, which can be mitigated by decreasing the infusion rate.
