Nursing Elites

1. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?

• A. Encourage the client to eat foods rich in potassium
• B. Administer a potassium-sparing diuretic
• C. Administer a potassium-binding medication
• D. Hold all medications containing potassium

Correct answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.

2. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

3. A client receiving full-strength continuous enteral tube feeding develops diarrhea. What intervention should the nurse take?

• A. Stop the feeding and provide IV fluids.
• B. Dilute the feeding to half strength and continue at the same rate.
• C. Reduce the feeding rate and monitor for improvement.
• D. Add fiber to the client's diet to resolve diarrhea.

Correct answer: B

Rationale: When a client develops diarrhea from continuous enteral tube feeding, diluting the feeding to half strength and continuing at the same rate is the appropriate intervention. This helps reduce the strength of the feeding, minimizing gastrointestinal upset while still providing necessary nutrition. Stopping the feeding abruptly (Choice A) may lead to nutritional deficits. Simply reducing the feeding rate (Choice C) may not effectively address the issue of diarrhea. Adding fiber (Choice D) could potentially worsen the diarrhea in this scenario instead of resolving it.

4. A client with a history of closed head injury has a radial artery catheter in place and complains of numbness and pain distal to the insertion site. What action should the nurse take?

• A. Monitor the site for further complications.
• B. Promptly remove the catheter from the radial artery.
• C. Elevate the client’s arm above the heart.
• D. Notify the healthcare provider and prepare for surgery.

Correct answer: B

Rationale: A weak pulse and numbness distal to a radial artery catheter may indicate occlusion or damage to the artery, and immediate removal of the catheter is necessary to prevent complications. Therefore, promptly removing the catheter from the radial artery (Choice B) is the correct action. Monitoring the site (Choice A) would delay necessary intervention, elevating the client's arm (Choice C) may not address the underlying issue, and notifying the healthcare provider for surgery (Choice D) without removing the catheter promptly could lead to further complications.

5. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

• A. Prothrombin time (PT)
• B. Hemoglobin and hematocrit (H&H)
• C. International Normalized Ratio (INR)
• D. Partial thromboplastin time (PTT)

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.
