Nursing Elites

1. Which of the following is a potassium-sparing diuretic?

• A. Furosemide
• B. Spironolactone
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

2. What is the therapeutic use of metformin?

• A. Lower blood pressure
• B. Diminish seizure activity
• C. The maintenance of a person's blood glucose levels
• D. Increase heart rate and decrease gastrointestinal secretions

Correct answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

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 is being educated by a healthcare provider about managing Digoxin toxicity. Which statement by the client demonstrates an understanding of the teaching?

• A. I will take an extra dose of Digoxin if I miss one.
• B. I should notify my healthcare provider if I experience visual changes.
• C. I will stop taking Digoxin if my heart rate is below 70 bpm.
• D. I should take antacids to alleviate gastrointestinal upset.

Correct answer: B

Rationale: The correct answer is B. Visual changes, such as yellow or blurred vision, can be indicative of digoxin toxicity. It is crucial for clients to inform their healthcare provider promptly if they encounter these symptoms. Prompt medical attention can help manage potential toxicity and prevent complications. Choices A, C, and D are incorrect because taking an extra dose of Digoxin, stopping Digoxin based on heart rate alone, and using antacids for gastrointestinal upset are not appropriate actions when managing Digoxin toxicity.

5. A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?

• A. Fomepizole
• B. Naloxone
• C. Phytonadione
• D. Diphenhydramine

Correct answer: D

Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms. Fomepizole is used in methanol or ethylene glycol poisoning, not for acute dystonia. Naloxone is an opioid antagonist used for opioid overdose, not for acute dystonia. Phytonadione is vitamin K, used for the reversal of warfarin, not for acute dystonia.
