Nursing Elites

1. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

2. A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: Patients prescribed methotrexate should be advised to take folic acid supplements as prescribed. Methotrexate can deplete folic acid levels, leading to side effects. By taking folic acid supplements as directed, the patient can reduce the risk of experiencing adverse effects associated with methotrexate therapy. It is important to note that the effects of methotrexate may not be immediate, so realistic expectations should be set with the patient. Alcohol should be avoided while taking methotrexate due to potential interactions and increased risk of liver toxicity. There is no specific recommendation to limit fluid intake to 1 liter per day in relation to methotrexate therapy.

3. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

4. A client with peptic ulcer disease is prescribed ranitidine (Zantac). Which statement by the client indicates the need for further teaching?

• A. I will take this medication at bedtime.
• B. I need to avoid smoking while taking this medication.
• C. I should take this medication with meals.
• D. This medication will help reduce stomach acid.

Correct answer: C

Rationale: The client's statement that they should take ranitidine with meals indicates a need for further teaching. Ranitidine is typically taken at bedtime or before meals to be most effective in reducing stomach acid. Taking it with meals may not provide the optimal therapeutic effect.

5. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.
