Nursing Elites

1. Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?

• A. Fasting blood glucose levels.
• B. Postprandial blood glucose levels.
• C. Hemoglobin A1c.
• D. Random blood glucose levels.

Correct answer: C

Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

2. The nurse is preparing to administer digoxin to a patient who is newly admitted to the intensive care unit. The nurse reviews the patient’s admission electrolytes and notes a serum potassium level of 2.9 mEq/L. Which action by the nurse is correct?

• A. Administer the digoxin and monitor the patient’s electrocardiogram closely.
• B. Hold the digoxin dose and notify the provider of the patient’s lab values.
• C. Request an order for an intravenous bolus of potassium.
• D. Request an order for oral potassium supplements.

Correct answer: B

Rationale: In the scenario presented, the patient has a low serum potassium level, which can predispose the patient to digoxin toxicity. It is essential for the nurse to hold the digoxin dose and promptly notify the healthcare provider of the abnormal lab values. Option A is incorrect because administering digoxin without addressing the low potassium level can potentiate toxicity. Option C is inappropriate as potassium should not be given as an IV bolus, especially in the case of hypokalemia. Option D is incorrect because oral potassium supplements may not be sufficient for rapidly correcting severe hypokalemia in an acute care setting.

3. The nurse is providing discharge teaching to a client with coronary artery disease (CAD). Which of the following statements by the client indicates a need for further teaching?

• A. I will take my medication only when I have chest pain.
• B. I will follow a heart-healthy diet and exercise regularly.
• C. I will avoid smoking and limit alcohol intake.
• D. I will contact my doctor if I experience chest pain or shortness of breath.

Correct answer: A

Rationale: The statement indicates a misunderstanding because medication for CAD should be taken as prescribed, not only when chest pain occurs.

4. A female patient will receive doxycycline to treat a sexually transmitted infection (STI). What information will the nurse include when teaching this patient about this medication?

• A. Nausea and vomiting are uncommon adverse effects.
• B. The drug may cause possible teratogenic effects.
• C. Increase intake of dairy products with each dose of this medication.
• D. Use a backup method of contraception if taking oral contraceptives.

Correct answer: D

Rationale: The correct answer is D. The desired action of oral contraceptives can be reduced when taken with tetracyclines like doxycycline. Therefore, patients on oral contraceptives should be advised to use a backup contraception method while taking doxycycline. Choice A is incorrect because nausea and vomiting are common adverse effects of doxycycline. Choice B is incorrect because doxycycline is not known for causing teratogenic effects. Choice C is incorrect because dairy products can interfere with the absorption of doxycycline, so they should be avoided when taking this medication.

5. An adult who was recently diagnosed with glaucoma tells the nurse, 'it feels like I am driving through a tunnel.' The client expresses great concern about going blind. Which nursing instruction is most important for the nurse to provide this client?

• A. Maintain prescribed eye drop regimen
• B. Avoid frequent eye pressure measurements
• C. Wear prescription glasses
• D. Eat a diet high in carotene

Correct answer: A

Rationale: The correct answer is A: Maintain prescribed eye drop regimen. In glaucoma, maintaining the prescribed eye drop regimen is crucial for controlling intraocular pressure, which helps in preventing vision loss. Consistent use of eye drops as directed can slow down the progression of the disease and preserve vision. Choice B is incorrect because avoiding frequent eye pressure measurements does not address the primary treatment for glaucoma. Choice C is incorrect as wearing prescription glasses may be helpful for vision correction but does not directly address the management of glaucoma. Choice D is incorrect because while a diet high in carotene may promote overall eye health, it is not the most important instruction for managing glaucoma.
