Nursing Elites

1. A client has a serum potassium level of 6.5 mmol/L, a serum creatinine level of 2 mg/dL, and a urine output of 350 mL/day. What is the best action by the nurse?

• A. Place the client on a cardiac monitor immediately.
• B. Teach the client to limit high-potassium foods.
• C. Continue to monitor the client’s intake and output.
• D. Ask to have the laboratory redraw the blood specimen.

Correct answer: A

Rationale: The best immediate action by the nurse in this situation is to place the client on a cardiac monitor immediately. A serum potassium level of 6.5 mmol/L indicates hyperkalemia, which can lead to life-threatening dysrhythmias. Monitoring the cardiac status is crucial to detect any potential arrhythmias promptly. Teaching the client to limit high-potassium foods (Choice B) may be important for long-term management, but it is not the priority at this moment. Continuing to monitor intake and output (Choice C) is important for assessing renal function but does not address the immediate risk of dysrhythmias. Asking to have the laboratory redraw the blood specimen (Choice D) is unnecessary since the current results indicate a critical situation that requires immediate action.

2. 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.

3. An older female client has normal saline infusing at 45 mL/hour. She complains of pain at the insertion site of the IV catheter. There is no redness or edema around the IV site. Which action should the nurse take?

• A. Determine which IV medications have recently been administered.
• B. Explain that without redness or edema, there is no need to re-start the IV.
• C. Consult with the healthcare provider about the best location to start a new IV.
• D. Convert the IV to a saline lock and continue to monitor the site.

Correct answer: D

Rationale: Converting the IV to a saline lock and continuing to monitor the site is the correct action in this scenario. When a client complains of pain at the IV insertion site without redness or edema, it may indicate phlebitis or irritation. Replacing the IV may not be necessary if there are no signs of infection or infiltration. Determining the IV medications administered or consulting with the healthcare provider to start a new IV are not immediate actions required for pain management at the insertion site. Therefore, the most appropriate intervention is to convert the IV to a saline lock and closely observe for any changes or complications.

4. The client with chronic renal failure is being educated about the importance of a low-sodium diet. Which of the following statements by the client indicates a need for further teaching?

• A. I can eat canned vegetables as long as I rinse them first.
• B. I can use table salt sparingly.
• C. I can eat frozen dinners if they are labeled low-sodium.
• D. I can eat whatever I want as long as I avoid salty foods.

Correct answer: B

Rationale: The correct answer is B. Clients with chronic renal failure need to strictly limit their sodium intake. Advising the client to use table salt sparingly is incorrect as they should avoid table salt altogether to adhere to a low-sodium diet. Choice A is correct as rinsing canned vegetables can help reduce their sodium content. Choice C is correct as consuming frozen dinners labeled low-sodium can be a suitable option. Choice D is incorrect as it implies that avoiding only salty foods is sufficient, when in fact, overall sodium intake needs to be monitored closely.

5. The best indicator that the client has learned how to give an insulin self-injection correctly is when the client can:

• A. Perform the procedure safely and correctly.
• B. Critique the nurse's performance of the procedure.
• C. Explain all steps of the procedure correctly.
• D. Correctly answer a post-test about the procedure.

Correct answer: A

Rationale: The best indicator of learning is the ability to perform the procedure safely and correctly, demonstrating skill acquisition. Choice A is correct because the client's ability to perform the insulin self-injection safely and correctly shows practical understanding and application of the skill. Choice B is incorrect because critiquing the nurse's performance does not necessarily demonstrate the client's ability to carry out the procedure themselves. Choice C is incorrect as merely explaining the steps verbally does not confirm the client's practical execution of the task. Choice D is also incorrect as answering a post-test does not directly assess the client's ability to physically perform the insulin self-injection.
