Nursing Elites

1. A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?

• A. Take the medication at the same time each day.
• B. Avoid foods high in potassium.
• C. Skip a dose if you feel well.
• D. Take the medication on an empty stomach.

Correct answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm. Choices B, C, and D are incorrect because avoiding potassium-rich foods, skipping doses when feeling well, and taking the medication on an empty stomach are not relevant or appropriate instructions for a client prescribed digoxin.

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

• A. You should have your white blood cell count checked regularly.
• B. You should take this medication on an empty stomach.
• C. You should avoid eating foods high in tyramine.
• D. You should avoid taking this medication with milk.

Correct answer: A

Rationale: The correct answer is A: 'You should have your white blood cell count checked regularly.' Clozapine can lead to agranulocytosis, a serious condition characterized by a low white blood cell count. Regular monitoring of the white blood cell count is crucial to detect this adverse effect early and prevent serious complications. Choices B, C, and D are incorrect because taking clozapine on an empty stomach, avoiding foods high in tyramine, or avoiding taking the medication with milk are not specific instructions related to the potential adverse effect of agranulocytosis associated with clozapine.

3. The nurse is teaching a client about lifestyle changes to manage hypertension. Which dietary change should the nurse recommend?

• A. Increase intake of red meat
• B. Use salt substitutes liberally
• C. Limit sodium intake to 2 grams per day
• D. Increase intake of processed foods

Correct answer: C

Rationale: The correct answer is C: 'Limit sodium intake to 2 grams per day.' This recommendation is crucial in managing hypertension because excessive sodium intake can lead to elevated blood pressure. Reducing sodium intake helps the body regulate fluid balance and lower blood pressure. Choices A, B, and D are incorrect. Increasing red meat intake can worsen hypertension due to its high saturated fat content. Using salt substitutes liberally can also be harmful as they often contain high amounts of potassium, which can be problematic for individuals with certain health conditions. Increasing processed foods consumption is generally discouraged in hypertension management due to their high sodium content and low nutritional value.

4. The nurse is caring for a client with hypertension who is prescribed a thiazide diuretic. The nurse should check which parameter before administering the medication?

• A. Serum potassium level
• B. Blood pressure
• C. Heart rate
• D. Serum sodium level

Correct answer: B

Rationale: Before administering a thiazide diuretic to a client with hypertension, the nurse should check the blood pressure. Thiazide diuretics are prescribed to lower blood pressure, so assessing the client's blood pressure prior to administration helps to monitor the effectiveness of the medication and to ensure the client's safety. Checking the serum potassium level (Choice A), heart rate (Choice C), or serum sodium level (Choice D) are also important parameters in the care of a client on a thiazide diuretic, but the priority assessment before administering the medication is the blood pressure to evaluate the drug's effectiveness in managing hypertension.

5. The healthcare provider notes this rhythm on the client's cardiac monitor. The healthcare provider next reports that the client is experiencing which heart rhythm?

• A. Normal sinus
• B. Atrial fibrillation
• C. Sinus bradycardia
• D. Ventricular fibrillation

Correct answer: B

Rationale: The correct answer is B, Atrial fibrillation. Atrial fibrillation is characterized by an irregular and often rapid heart rate, which can lead to poor blood flow due to ineffective contractions of the atria. Sinus bradycardia (Choice C) is a regular but slow heart rhythm originating from the sinus node. Normal sinus rhythm (Choice A) refers to a regular heartbeat originating from the sinus node. Ventricular fibrillation (Choice D) is a life-threatening arrhythmia characterized by rapid, uncoordinated contractions of the ventricles.
