Nursing Elites

1. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Blood urea nitrogen (BUN) of 45 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

2. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?

• A. Remove the needle after discarding used syringes
• B. Wear gloves while disposing of the needle and syringe
• C. Wear a face mask during medication administration
• D. Wash hands before handling the needle and syringe

Correct answer: D

Rationale: The correct answer is D. Washing hands before handling the needle and syringe is a critical step in infection control and adherence to standard precautions. Clean hands help prevent the transfer of microorganisms and reduce the risk of infection. Choices A, B, and C do not directly relate to standard precautions. Removing the needle after discarding used syringes (Choice A) can increase the risk of needlestick injuries. Wearing gloves while disposing of the needle and syringe (Choice B) is important for personal protection but does not specifically address standard precautions. Wearing a face mask during medication administration (Choice C) is not directly related to handling syringes and needles, which are more pertinent to standard precautions.

3. A nurse is caring for a client who has a new prescription for tube feeding. The nurse understands that the provider prescribed tube feeding because the client:

• A. Is unable to swallow foods by mouth
• B. Has a gastrointestinal obstruction
• C. Requires additional caloric intake to support healing
• D. Is at risk for aspiration

Correct answer: A

Rationale: The correct answer is A: 'Is unable to swallow foods by mouth.' Tube feeding is prescribed when a client is unable to safely swallow food by mouth but has a functional gastrointestinal tract. Option B, 'Has a gastrointestinal obstruction,' is incorrect as tube feeding is not typically prescribed for this reason. Option C, 'Requires additional caloric intake to support healing,' is incorrect because tube feeding is specifically for clients who are unable to swallow. Option D, 'Is at risk for aspiration,' is also incorrect as tube feeding would not be the primary intervention for aspiration risk; other strategies to reduce aspiration risk would be implemented instead.

4. A nurse is providing care to a 17-year-old client in the post-operative care unit (PACU) after an emergency appendectomy. Which finding is an early indication that the client is experiencing poor oxygenation?

• A. Abnormal breath sounds
• B. Cyanosis of the lips
• C. Increasing pulse rate
• D. Pulse oximeter reading of 92%

Correct answer: C

Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.

5. What is the most important action for preventing infection in a client with a central venous catheter?

• A. Changing the catheter dressing every 72 hours.
• B. Flushing the catheter with heparin solution daily.
• C. Ensuring the catheter is clamped when not in use.
• D. Maintaining sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.
