Nursing Elites

1. When teaching a client with a new prescription for Lithium, which instruction should the nurse include?

• A. Restrict fluid intake to 1,000 mL per day.
• B. Maintain a consistent sodium intake.
• C. Take the medication at bedtime.
• D. Expect to have frequent headaches.

Correct answer: B

Rationale: Maintaining a consistent sodium intake is crucial when taking Lithium to help regulate lithium levels in the body and prevent toxicity. Sodium levels can impact the effectiveness and safety of Lithium therapy. Restricting fluid intake to 1,000 mL per day (Choice A) is not appropriate and could lead to dehydration. Taking the medication at bedtime (Choice C) may vary depending on the individual's schedule but is not a critical instruction. Expecting to have frequent headaches (Choice D) is not a common side effect of Lithium.

2. A client receiving chemotherapy with Methotrexate asks why Leucovorin is being given. Which of the following responses should the nurse use?

• A. Leucovorin reduces the risk of a transfusion reaction from Methotrexate.
• B. Leucovorin increases platelet production and prevents bleeding.
• C. Leucovorin potentiates the cytotoxic effects of Methotrexate.
• D. Leucovorin protects healthy cells from Methotrexate's toxic effects.

Correct answer: D

Rationale: Leucovorin, a folic acid derivative and an antagonist to Methotrexate, is given within 12 hours of high doses of Methotrexate to protect healthy cells from the toxic effects of Methotrexate. It helps to reduce the bone marrow suppression and gastrointestinal side effects caused by Methotrexate, supporting the client's overall well-being during chemotherapy treatment. Choices A, B, and C are incorrect because Leucovorin does not reduce the risk of a transfusion reaction from Methotrexate, increase platelet production, prevent bleeding, or potentiate the cytotoxic effects of Methotrexate. Instead, Leucovorin works by rescuing healthy cells from the toxic effects of Methotrexate.

3. Which medication is contraindicated with Nitroglycerin?

• A. Hydrochloroquine
• B. Methylprednisolone
• C. Phenazopyridine
• D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.

4. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?

• A. Warfarin
• B. Amlodipine
• C. Nitroglycerin
• D. Clopidogrel

Correct answer: A

Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.

5. A client with heart failure is prescribed digoxin. Which of the following findings should the nurse identify as an adverse effect of digoxin?

• A. Constipation
• B. Blurred vision
• C. Nausea
• D. Headache

Correct answer: B

Rationale: Blurred vision is a common adverse effect of digoxin and can indicate toxicity. Monitoring for visual changes is essential to prevent serious complications in clients taking digoxin.
