Nursing Elites

1. A client receiving chemotherapy is being taught about infection prevention by a nurse. Which of the following instructions should the nurse include?

• A. Wear a mask when gardening.
• B. Avoid crowds to reduce the risk of infection.
• C. You should take a daily vitamin to prevent infection.
• D. Increase your intake of high-protein foods.

Correct answer: B

Rationale: The correct answer is B: 'Avoid crowds to reduce the risk of infection.' Clients receiving chemotherapy are immunocompromised, so avoiding crowds can help decrease the likelihood of exposure to infections. Wearing a mask when gardening (choice A) is important but not directly related to infection prevention in the context of chemotherapy. Taking a daily vitamin (choice C) may be beneficial for overall health but is not specifically focused on infection prevention. Increasing intake of high-protein foods (choice D) is essential for nutrition but does not directly address infection prevention.

2. A nurse is planning care for a client who has a closed head injury and has an intraventricular catheter. Which of the following interventions should the nurse include to reduce the risk for infection?

• A. Keep the head of the bed elevated to 30 degrees.
• B. Administer IV antibiotics prophylactically.
• C. Change the catheter insertion site every 24 hours.
• D. Monitor the insertion site for redness.

Correct answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

3. Which medication is commonly prescribed for patients with atrial fibrillation?

• A. Warfarin
• B. Digoxin
• C. Aspirin
• D. Lisinopril

Correct answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

4. A nurse is caring for a client who is receiving chemotherapy. Which of the following laboratory values should the nurse report to the provider?

• A. WBC 4,500/mm3
• B. Hemoglobin 12 g/dL
• C. Platelet count 250,000/mm3
• D. Platelet count 100,000/mm3

Correct answer: D

Rationale: The correct answer is D. A platelet count of 100,000/mm3 is lower than the normal range, indicating thrombocytopenia, which is concerning in clients receiving chemotherapy. Thrombocytopenia can lead to an increased risk of bleeding and bruising. Choices A, B, and C fall within the normal range and would not be a cause for concern in a client receiving chemotherapy.

5. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.
