Nursing Elites

1. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

2. A client is scheduled for a colonoscopy. Which preparation is the most important for the nurse to implement?

• A. Administer an enema before the procedure.
• B. Ensure the client is NPO after midnight.
• C. Encourage the client to drink clear liquids.
• D. Verify the client has completed the bowel preparation.

Correct answer: D

Rationale: The correct answer is to verify that the client has completed the bowel preparation. This step is crucial to ensure the colon is clear for accurate visualization during the procedure. Administering an enema before the procedure may not always be necessary and can be uncomfortable for the client. Ensuring the client is NPO after midnight is important, but verifying bowel preparation takes precedence. Encouraging the client to drink clear liquids is a part of the preparation process but not the most critical step compared to verifying completion of bowel preparation.

3. In the critical care unit, which client should receive the most care hours by a registered nurse (RN)?

• A. A client with a newly inserted Foley catheter and Alzheimer's disease
• B. A 55-year-old with chronic kidney disease
• C. An 82-year-old client with a newly fractured femur and soft wrist restraints
• D. A 72-year-old with pneumonia and sepsis on antibiotics

Correct answer: C

Rationale: The client with a newly fractured femur and soft wrist restraints should receive the most care hours as they have physical limitations due to the fracture and mental limitations due to being restrained. This client requires continuous monitoring, support, and frequent assessments to prevent complications. Choices A, B, and D do not have the same level of physical and mental care needs as the client with the newly fractured femur and soft wrist restraints.

4. The nurse is caring for a client with fluid overload. The most reliable indicator of fluid volume status is

• A. Body weight
• B. Intake and output
• C. Daily weight
• D. Skin turgor

Correct answer: C

Rationale: Daily weight is the most reliable indicator of fluid volume status as it reflects changes in body fluid balance accurately. Body weight alone can fluctuate due to various factors, including food intake and bowel movements, which may not accurately represent fluid status. Intake and output provide information on fluid balance over time but may not reflect immediate changes. Skin turgor is a physical assessment finding that indicates hydration status, not overall fluid volume status.

5. A client in labor is experiencing late decelerations in fetal heart rate. What intervention should the nurse perform first?

• A. Reposition the client onto her left side.
• B. Apply oxygen via nasal cannula.
• C. Prepare for an emergency cesarean section.
• D. Increase IV fluid administration to improve perfusion.

Correct answer: A

Rationale: Late decelerations indicate fetal distress due to compromised placental perfusion. Repositioning the client onto her left side is the priority intervention as it can increase blood flow to the placenta, improving fetal oxygenation. Applying oxygen via nasal cannula (choice B) can be the next step after repositioning if late decelerations persist. Emergency cesarean section (choice C) is not the initial action for late decelerations unless other interventions are ineffective. Increasing IV fluid administration (choice D) is not the first-line intervention for late decelerations; repositioning takes precedence to address the underlying cause.
