Nursing Elites

1. A nurse is caring for a client who is receiving enteral feedings through a nasogastric tube. Which of the following findings should the nurse report to the provider?

• A. Gastric residual of 200 mL or more
• B. pH of gastric contents is 5.0
• C. Bowel sounds are present in all quadrants
• D. Temperature 37.5°C (99.5°F)

Correct answer: A

Rationale: The correct answer is A. A gastric residual of 200 mL or more indicates delayed gastric emptying, which can be a sign of potential complications such as aspiration or intolerance to the enteral feedings. This finding should be reported to the healthcare provider for further evaluation and possible intervention. Choices B, C, and D are within normal limits and do not require immediate reporting. A pH of 5.0 is normal for gastric contents, bowel sounds in all quadrants indicate normal gastrointestinal motility, and a temperature of 37.5°C (99.5°F) is within the normal range.

2. A healthcare professional is caring for a client who has a prescription for enoxaparin. Which of the following laboratory tests should the healthcare professional review before administering the medication?

• A. Prothrombin time (PT)
• B. INR
• C. Platelet count
• D. Potassium levels

Correct answer: D

Rationale: Corrected Rationale: Before administering enoxaparin, it is essential to review potassium levels to monitor for potential imbalances. Enoxaparin, a type of anticoagulant, does not directly affect PT, INR, or platelet count. Monitoring potassium levels is crucial to ensure the safety and effectiveness of the medication. PT and INR are typically used to monitor warfarin therapy, while platelet count is essential for assessing clotting function but is not directly related to enoxaparin administration.

3. A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.

4. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

5. Which electrolyte imbalance is commonly seen in patients taking furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.
