Nursing Elites

1. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?

• A. Use the catheter for the next laboratory blood draw.
• B. Monitor the central venous pressure through this line.
• C. Access the line for the next intravenous medication.
• D. Place a heparin or heparin/saline dwell after hemodialysis.

Correct answer: D

Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.

2. A client has an elevated blood urea nitrogen (BUN)/creatinine ratio. Which action should the nurse take first?

• A. Assess the client’s dietary habits.
• B. Inquire about the client's use of nonsteroidal anti-inflammatory drugs (NSAIDs).
• C. Hold the client’s metformin (Glucophage).
• D. Contact the health care provider immediately.

Correct answer: A

Rationale: An elevated blood urea nitrogen (BUN)/creatinine ratio can indicate various conditions such as dehydration, urinary obstruction, catabolism, or a high-protein diet. The initial action the nurse should take is to assess the client’s dietary habits to determine if the elevated ratio is related to diet. Inquiring about the use of NSAIDs is important as they can impact kidney function, but dietary causes should be ruled out first. Holding metformin or contacting the health care provider without assessing the dietary habits would be premature actions as they may not address the underlying cause of the elevated BUN/creatinine ratio.

3. A client is tested for HIV with the use of an enzyme-linked immunosorbent assay (ELISA), and the test result is positive. The nurse should tell the client that:

• A. HIV infection has been confirmed
• B. The client probably has an opportunistic infection
• C. The test will need to be confirmed with the use of a Western blot
• D. A positive test is a normal result and does not mean that the client is infected with HIV

Correct answer: C

Rationale: When an ELISA test for HIV is positive, it is essential to confirm the result with a Western blot. The Western blot is the confirmatory test for HIV. Choice A is incorrect because a positive ELISA test does not confirm HIV infection. Choice B is incorrect as it assumes a different diagnosis. Choice D is incorrect because a positive ELISA test does indicate potential HIV infection and requires confirmation.

4. 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.

5. The patient is receiving sulfadiazine. The healthcare provider knows that this patient’s daily fluid intake should be at least which amount?

• A. 1000 mL/day
• B. 1200 mL/day
• C. 2000 mL/day
• D. 2400 mL/day

Correct answer: C

Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.
