Nursing Elites

1. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

• A. Hyponatremia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.

2. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?

• A. NPO except for metformin and regular snacks
• B. NPO except for oral antidiabetic agent
• C. Novolin-N insulin subcutaneously twice daily
• D. Regular insulin subcutaneously per sliding scale

Correct answer: D

Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.

3. A client is taking levodopa-carbidopa for Parkinson's disease. The nurse should include which instruction when educating the client about this medication?

• A. Increase fluid intake to prevent dehydration.
• B. Take medication with food to improve absorption.
• C. Take medication at bedtime to avoid daytime drowsiness.
• D. It can cause nausea and dizziness.

Correct answer: A

Rationale: The correct instruction for a client taking levodopa-carbidopa for Parkinson's disease is to increase fluid intake to prevent dehydration. Levodopa-carbidopa should be taken with food to reduce gastrointestinal upset and improve absorption. Taking medication at bedtime is not necessary to avoid daytime drowsiness. It is crucial to prevent dehydration due to the medication's side effects. Choice B is incorrect because the medication should be taken with food, not at bedtime. Choice C is incorrect as taking the medication with food, rather than on an empty stomach, aids in absorption and reduces gastrointestinal side effects. Choice D is incorrect as it states the side effects of the medication rather than providing specific instructions on its administration.

4. A client diagnosed with seizures is prescribed phenytoin. Which medication instruction should the practical nurse (PN) reinforce to this client?

• A. Maintain consistent sodium intake.
• B. Use sunscreen when outdoors.
• C. Return for monthly urinalysis.
• D. Brush and floss teeth daily.

Correct answer: D

Rationale: The correct answer is to reinforce the instruction to brush and floss teeth daily. Phenytoin therapy can lead to gingival hyperplasia (gum disease), which can be prevented by maintaining good oral hygiene practices such as brushing and flossing daily. Choices A, B, and C are incorrect because they are not directly related to the side effects or management of phenytoin therapy. Maintaining consistent sodium intake is not a specific concern with phenytoin. Using sunscreen when outdoors is important to prevent sunburn but is not directly related to phenytoin therapy. Returning for monthly urinalysis may be necessary for other medications, but it is not specifically required for monitoring phenytoin therapy.

5. A client with a history of heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypernatremia

Correct answer: A

Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can lead to an excess of potassium in the body, causing hyperkalemia. This medication inhibits the action of aldosterone, leading to decreased potassium excretion and potential retention. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias, especially in clients with heart failure.
