Nursing Elites

1. 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.

2. What is the classification of Ondansetron?

• A. Antihypertensive
• B. Antiarrhythmic
• C. Antiemetic
• D. Antiulcer agent

Correct answer: C

Rationale: Ondansetron is classified as an antiemetic. It is commonly used to prevent nausea and vomiting, especially in patients undergoing chemotherapy or surgery. Choice A, Antihypertensive, is incorrect as Ondansetron is not used to treat high blood pressure. Choice B, Antiarrhythmic, is incorrect as Ondansetron is not used to manage heart rhythm abnormalities. Choice D, Antiulcer agent, is incorrect as Ondansetron is not primarily indicated for treating ulcers.

3. When educating a client starting a new prescription for metoprolol, which instruction should the nurse include?

• A. Check your pulse before taking the medication.
• B. Take the medication with food to increase absorption.
• C. Avoid sudden changes in position.
• D. Monitor your blood pressure regularly.

Correct answer: C

Rationale: The correct instruction for a client starting metoprolol is to avoid sudden changes in position. Metoprolol can cause dizziness due to its blood pressure-lowering effects, increasing the risk of falls and injury. Instructing the client to change positions slowly helps prevent orthostatic hypotension and related adverse events. Checking the pulse before taking the medication (Choice A) is not typically necessary for metoprolol. Taking the medication with food (Choice B) is not required for absorption and can be taken with or without food. Monitoring blood pressure regularly (Choice D) is essential for clients taking metoprolol, but avoiding sudden changes in position is more critical to prevent dizziness and falls.

4. A client has a new prescription for Timolol. How should the nurse instruct the client to insert eye drops?

• A. Press your finger on the inside corner of your eye for 1 minute after application.
• B. Apply the eye drops directly to the cornea.
• C. Drop the prescribed amount of medication into the center of the conjunctival sac.
• D. Wipe your eyes gently with a tissue immediately after application.

Correct answer: C

Rationale: When administering eye drops, it is essential to instruct the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps ensure proper distribution of the medication and reduces the risk of potential adverse effects. Pressing on the inside corner of the eye is done to prevent systemic absorption, applying drops directly to the cornea can cause irritation, and wiping the eyes after application can lead to decreased effectiveness of the medication.

5. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

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

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.
