Nursing Elites

1. A healthcare provider is reviewing the medical record of a client who has a new prescription for clozapine. Which of the following findings indicates a contraindication to clozapine?

• A. Fasting blood glucose of 120 mg/dL
• B. Asthma
• C. Hypertension
• D. WBC count of 3,300/mm3

Correct answer: D

Rationale: A low WBC count (3,300/mm3) is a contraindication to clozapine because this medication can cause severe neutropenia. Neutropenia is a significant reduction in white blood cell count, increasing the risk of infections. Elevated fasting blood glucose, asthma, and hypertension are not direct contraindications to clozapine.

2. A patient is admitted with signs of stroke. Which of the following diagnostic tests should the nurse anticipate as the priority?

• A. CT scan
• B. MRI
• C. X-ray
• D. Ultrasound

Correct answer: A

Rationale: A CT scan is the priority diagnostic test to identify and confirm the location and severity of a stroke.

3. A nurse is evaluating a client receiving hemodialysis. Which of the following lab values requires immediate intervention?

• A. Sodium 135 mEq/L
• B. Potassium 6.5 mEq/L
• C. Calcium 9 mg/dL
• D. Chloride 98 mEq/L

Correct answer: B

Rationale: The correct answer is B. Potassium levels above 5.0 mEq/L can lead to cardiac issues, and a level of 6.5 mEq/L requires immediate intervention. Hyperkalemia can cause life-threatening cardiac arrhythmias. Choices A, C, and D are within normal ranges and do not require immediate intervention in the context of hemodialysis monitoring.

4. A client with severe dyspnea is scheduled for multiple diagnostic tests. Which test should the nurse prioritize?

• A. Administer an echocardiogram first.
• B. Prioritize a chest x-ray for the client.
• C. Prepare the client for a CT scan.
• D. Order an MRI first.

Correct answer: B

Rationale: The correct answer is B: Prioritize a chest x-ray for the client. When a client presents with severe dyspnea, a chest x-ray should be prioritized as it helps in assessing the lungs and heart, which are crucial in cases of respiratory distress. Echocardiograms are more focused on assessing heart function and may not provide immediate information needed in cases of dyspnea. CT scans and MRIs are more detailed imaging studies that are not typically the first-line diagnostic tests for severe dyspnea.

5. A healthcare provider is preparing to administer digoxin to a patient with heart failure. Which of the following lab results should be reviewed before administering the medication?

• A. Potassium level
• B. Calcium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: The correct answer is A: Potassium level. Hypokalemia increases the risk of digoxin toxicity. Digoxin can potentiate the effects of low potassium levels, leading to life-threatening arrhythmias. Therefore, it is essential to review the patient's potassium level before administering digoxin. Choices B, C, and D are incorrect because calcium level, hemoglobin level, and white blood cell count are not directly related to the risk of digoxin toxicity.
