Nursing Elites

1. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?

• A. Aspirin
• B. Isosorbide
• C. Clopidogrel
• D. Atorvastatin

Correct answer: B

Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.

2. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take one tablet at the first sign of chest pain.
• B. If pain is not relieved, take another tablet in 10 minutes.
• C. You can take up to five tablets in 15 minutes.
• D. Swallow the tablet with water.

Correct answer: A

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet at the first sign of chest pain. If the pain is not relieved after 5 minutes, the client should call 911 and take a second tablet. Taking more than the recommended dose can lead to serious side effects, and swallowing the tablet would not provide the rapid effect needed in cases of chest pain. Choice A is correct because it aligns with the standard protocol for nitroglycerin use in treating angina. Choice B is incorrect as the second tablet should be taken after 5 minutes, not 10 minutes. Choice C is incorrect as taking up to five tablets in 15 minutes is excessive and can result in serious complications. Choice D is incorrect as nitroglycerin sublingual tablets should be placed under the tongue for rapid absorption, not swallowed.

3. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.

4. A client has a new prescription for Verapamil to control hypertension. Which of the following instructions should the nurse include?

• A. Increase the amount of dietary fiber in the diet.
• B. Drink grapefruit juice daily to increase vitamin C intake.
• C. Decrease the amount of calcium in the diet.
• D. Withhold food for 1 hr after taking the medication.

Correct answer: A

Rationale: Increasing dietary fiber intake is essential when taking Verapamil to prevent constipation, a common adverse effect of the medication. Dietary fiber can help maintain bowel regularity and alleviate constipation.

5. 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.
