Nursing Elites

1. A nurse is reviewing the medical record of a client who is receiving gentamicin for a wound infection. Which of the following findings should the nurse report to the provider?

• A. Blood urea nitrogen (BUN) 25 mg/dL
• B. Serum creatinine 1.5 mg/dL
• C. Serum glucose 110 mg/dL
• D. White blood cell (WBC) count 5,000/mm3

Correct answer: A

Rationale: An elevated BUN level indicates possible nephrotoxicity, which is a side effect of gentamicin and should be reported. Elevated serum creatinine and WBC count are not specifically related to gentamicin therapy. Normal serum glucose levels are also within the expected range.

2. 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.

3. A client who has glaucoma and a new prescription for timolol eyedrops is receiving teaching from a nurse. Which of the following statements indicates an understanding of the teaching?

• A. I will place the eye drops in the center of my eye.
• B. I will place pressure on the corner of my eye after using the drops.
• C. I should expect my tears to turn red after using the drops.
• D. I should expect the drops to appear cloudy.

Correct answer: B

Rationale: The correct answer is B because placing pressure on the corner of the eye after using the drops helps in better absorption. Option A is incorrect because eye drops should be placed in the conjunctival sac, not the center of the eye. Option C is incorrect because tears turning red is not an expected outcome of using timolol eyedrops. Option D is incorrect because timolol eyedrops should not appear cloudy.

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

• A. Take this medication with food to prevent nausea.
• B. Notify your provider if you experience visual disturbances.
• C. Take an antacid with this medication if indigestion occurs.
• D. Avoid taking this medication if your heart rate is less than 60/min.

Correct answer: B

Rationale: The correct instruction for a client taking digoxin is to notify their provider if they experience visual disturbances. Visual disturbances can be a sign of digoxin toxicity, and prompt notification to the healthcare provider is essential for timely intervention. Choice A is incorrect because digoxin should be taken on an empty stomach for better absorption. Choice C is incorrect because antacids can interfere with the absorption of digoxin. Choice D is incorrect because a heart rate less than 60/min is not a sole reason to avoid taking digoxin; rather, it is important to monitor the heart rate and consult with the healthcare provider if there are concerns.

5. A client who is taking phenytoin is being taught about contraceptive options. Which of the following statements should the nurse make?

• A. You should use a backup method of birth control while taking phenytoin.
• B. Phenytoin can decrease the effectiveness of oral contraceptives.
• C. You should stop taking phenytoin while using oral contraceptives.
• D. Phenytoin can increase the effectiveness of oral contraceptives.

Correct answer: B

Rationale: The correct answer is B. Phenytoin can decrease the effectiveness of oral contraceptives, so it is important to inform the client about this interaction. Using an additional form of contraception, such as a backup method, is recommended to ensure adequate protection against pregnancy. Choice A is incorrect because it lacks specificity about the decrease in effectiveness of oral contraceptives caused by phenytoin. Choice C is incorrect as it suggests stopping phenytoin use while using oral contraceptives, which is not the appropriate action. Choice D is incorrect as phenytoin is known to decrease, not increase, the effectiveness of oral contraceptives.
