Nursing Elites

1. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

2. Which client requires careful nursing assessment for signs and symptoms of hypomagnesaemia?

• A. A young adult client with intractable vomiting due to food poisoning
• B. A client who developed hyperparathyroidism in late adolescence
• C. A middle-aged male client in renal failure following an unsuccessful kidney transplant
• D. A female client who excessively consumes simple carbohydrates

Correct answer: C

Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.

3. The nurse working in an emergency center collects physical evidence 6 hours following a reported sexual assault. After placing the samples in sealed containers, which action is most important for the nurse to implement?

• A. Maintain possession of the evidence collection kit at all times until submitted to law enforcement
• B. Provide discharge instructions for prophylactic antibiotics, pregnancy, and HIV prevention medication
• C. Document the characteristics of the various sites of sample collection
• D. Assist the client with toileting, hygiene, and dressing with clean clothes

Correct answer: A

Rationale: Maintaining possession of the evidence collection kit at all times until submitted to law enforcement is crucial to ensure the integrity of the chain of custody. This step helps prevent tampering or contamination of the evidence, which is vital for the legal process. Providing discharge instructions for medications, documenting sample characteristics, and assisting the client with personal care are important aspects of care but not the immediate priority when handling forensic evidence in a sexual assault case.

4. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client reports difficulty breathing. What action should the nurse take first?

• A. Increase the oxygen flow rate
• B. Instruct the client to breathe deeply and cough
• C. Check the client's oxygen saturation level
• D. Place the client in a high-Fowler's position

Correct answer: C

Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.

5. The nurse is preparing to administer medications to a client with a nasogastric tube. Which action should the nurse take first?

• A. Check for tube placement
• B. Crush the medications
• C. Flush the tube with water
• D. Administer the medications

Correct answer: A

Rationale: The correct first action when administering medications to a client with a nasogastric tube is to check for tube placement. This is crucial to ensure that the medications are delivered to the correct location within the gastrointestinal tract. Checking the tube placement helps prevent complications such as medication entering the lungs if the tube is misplaced. Crushing the medications (choice B) or flushing the tube with water (choice C) should only be done after confirming the correct tube placement. Administering the medications (choice D) without verifying the tube placement can lead to serious consequences.
