Nursing Elites

1. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.

2. A client with chronic heart failure is being taught by a nurse about the importance of daily weights. Which of the following instructions should the nurse include?

• A. Weigh yourself at the same time every day.
• B. Use the same scale for weighing each time.
• C. Record your weight in a journal or log.
• D. Report any weight gain of more than 2 to 3 pounds in a day.

Correct answer: D

Rationale: The correct instruction for a client with chronic heart failure is to report any weight gain of more than 2 to 3 pounds in a day. This weight gain may indicate fluid retention, which is a critical sign of worsening heart failure. Weighing at the same time every day and using the same scale for consistency are good practices, but the crucial action is to promptly report significant weight gain, as stated in option D. Recording the weight in a journal or log can be helpful for tracking trends, but immediate reporting of weight gain is essential for timely intervention in heart failure management. Therefore, option D is the most appropriate instruction for this client.

3. The client has had a femoral-popliteal bypass surgery 6 hours ago. Which assessment provides the most accurate information about the client's postoperative status?

• A. Radial pulse.
• B. Femoral pulse.
• C. Apical pulse.
• D. Dorsalis pedis pulse.

Correct answer: D

Rationale: Assessing the dorsalis pedis pulse is crucial after a femoral-popliteal bypass surgery to determine adequate circulation distal to the surgical site. A strong dorsalis pedis pulse indicates sufficient blood flow to the foot, which is essential for monitoring postoperative status. The radial pulse (A) is not the most relevant assessment as it does not provide direct information on circulation in the lower extremities. The femoral pulse (B) may not accurately reflect circulation distal to the surgical site. The apical pulse (C) is used primarily to assess the heartbeat and cardiac function, not circulation in the lower extremities.

4. A client with peripheral arterial disease (PAD) has cool and pale feet with diminished pulses. Which of the following interventions should the nurse implement?

• A. Keep the legs elevated above the level of the heart.
• B. Encourage the client to exercise daily.
• C. Apply warm compresses to the affected area.
• D. Apply ice packs to the affected area.

Correct answer: C

Rationale: In peripheral arterial disease (PAD), there is decreased blood flow to the extremities. Applying warm compresses helps dilate blood vessels, improve circulation, and relieve symptoms. Elevating the legs above the heart level may further compromise blood flow. Encouraging daily exercise is important in PAD management but may not be appropriate when the client has cool, pale feet with diminished pulses. Applying ice packs can worsen vasoconstriction and further reduce blood flow, exacerbating symptoms in PAD.

5. 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.
