Nursing Elites

1. 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.

2. A client has a new prescription for digoxin. Which of the following instructions should the nurse include during discharge teaching?

• A. Take the medication with food.
• B. Monitor heart rate daily.
• C. Avoid consuming grapefruit juice.
• D. Increase intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Monitor heart rate daily.' When a client is prescribed digoxin, it is essential to monitor heart rate daily because digoxin can cause bradycardia, a condition characterized by a slow heart rate. Monitoring the heart rate regularly allows the client to promptly identify any signs of bradycardia and seek medical attention if needed. Choices A, C, and D are incorrect because taking digoxin with food, avoiding grapefruit juice, and increasing potassium-rich foods are not specific instructions related to managing the side effects or monitoring parameters of digoxin therapy.

3. The nurse is preparing to administer an intravenous dose of furosemide (Lasix) to a client with heart failure. The nurse should monitor for which potential side effect?

• A. Hypertension
• B. Hyperkalemia
• C. Hypokalemia
• D. Hypoglycemia

Correct answer: C

Rationale: Furosemide is a loop diuretic that works by promoting the excretion of water and electrolytes, including potassium. This loss of potassium can lead to hypokalemia, which can be a potential side effect of furosemide administration. Hypokalemia can result in cardiac dysrhythmias and other complications, especially in clients with heart failure who may already have compromised cardiac function. Therefore, monitoring for signs of hypokalemia, such as muscle weakness, cardiac irregularities, and fatigue, is essential when administering furosemide. Choice A, hypertension, is incorrect because furosemide is actually used to treat hypertension by reducing excess fluid in the body. Choice B, hyperkalemia, is incorrect as furosemide causes potassium loss, leading to hypokalemia. Choice D, hypoglycemia, is unrelated to the mechanism of action of furosemide and is not a common side effect associated with its administration.

4. 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.

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

• A. Take the medication with food.
• B. Monitor for signs of hypokalemia.
• C. Take the medication at bedtime.
• D. Monitor for a dry cough.

Correct answer: D

Rationale: The correct answer is to monitor for a dry cough. Captopril is known to cause a persistent dry cough as a common side effect. If a dry cough develops, it should be reported to the healthcare provider promptly, as it may necessitate discontinuation of the medication. Choice A is incorrect because captopril is usually taken on an empty stomach. Choice B is incorrect as hypokalemia is not a common side effect of captopril. Choice C is incorrect as captopril is typically taken during the day and not specifically at bedtime.
