Nursing Elites

1. A client with heart failure is receiving digoxin. Which finding should indicate to the nurse that the client is experiencing digoxin toxicity?

• A. Constipation
• B. Blurred vision
• C. Bradycardia
• D. Dry cough

Correct answer: C

Rationale: Bradycardia is a hallmark sign of digoxin toxicity. Digoxin, a medication used to treat heart conditions, can lead to toxicity manifesting as bradycardia. Bradycardia occurs due to the drug's effect on slowing down the heart rate excessively. Constipation (Choice A) is not typically associated with digoxin toxicity. Blurred vision (Choice B) is more commonly linked to visual disturbances caused by digoxin, but it is not a defining sign of toxicity. Dry cough (Choice D) is not a recognized symptom of digoxin toxicity. It is crucial for the nurse to recognize the early signs of digoxin toxicity to prevent serious complications and provide appropriate interventions promptly.

2. The LPN/LVN is assisting in the care of a client with a diagnosis of heart failure who is receiving digoxin (Lanoxin). Which laboratory result should the nurse monitor closely?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum glucose

Correct answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure. Serum sodium, serum calcium, and serum glucose levels are also important laboratory values to monitor in clients with heart failure, but they are not directly associated with the risk of digoxin toxicity. Monitoring these values helps in assessing overall health status, fluid balance, and metabolic functions in the client.

3. The client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Serum electrolytes
• D. Liver function tests

Correct answer: B

Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor the effectiveness of anticoagulant therapy, especially with heparin. A prolonged aPTT indicates effective anticoagulation, reducing the risk of further clot formation in the client with deep vein thrombosis (DVT). The other options, such as complete blood count (CBC), serum electrolytes, and liver function tests, do not directly assess the therapeutic effectiveness of anticoagulant therapy. Therefore, the correct answer is B.

4. A hypertensive client who has been taking metoprolol (Lopressor) has been prescribed to decrease the dose of the medication. The client asks the nurse why this must be done over a period of 1 to 2 weeks. In formulating a response, the nurse incorporates the understanding that abrupt withdrawal could affect the client in which way?

• A. Result in hypoglycemia
• B. Give the client insomnia
• C. Precipitate rebound hypertension
• D. Cause enhanced side effects of other prescribed medications

Correct answer: C

Rationale: Abruptly stopping metoprolol can lead to rebound hypertension, causing a sudden increase in blood pressure due to the sudden withdrawal of the medication. Gradually tapering the dose helps the body adjust and reduces the risk of this adverse effect. Choices A, B, and D are incorrect. Stopping metoprolol suddenly is not known to result in hypoglycemia, insomnia, or enhanced side effects of other medications.

5. The nurse is teaching a client with coronary artery disease (CAD) about the risk factors for the disease. Which modifiable risk factor should the nurse emphasize?

• A. Family history
• B. Age
• C. Cigarette smoking
• D. Gender

Correct answer: C

Rationale: Cigarette smoking is a modifiable risk factor for coronary artery disease (CAD) as it can be changed or controlled to reduce the risk of developing CAD. Family history, age, and gender are non-modifiable risk factors that cannot be changed. Emphasizing the importance of quitting smoking can help the client reduce their risk of CAD and improve their overall cardiovascular health. Therefore, the correct answer is C. Choice A (Family history), B (Age), and D (Gender) are non-modifiable risk factors and not the focus of modifiable risk reduction strategies in CAD prevention.
