Nursing Elites

1. A healthcare professional is reviewing a client's laboratory results. Which of the following values is a contraindication to the administration of heparin?

• A. Hemoglobin 13 g/dL
• B. Platelet count 50,000/mm³
• C. White blood cell count 6,000/mm³
• D. INR 2.5

Correct answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm³. A platelet count of 50,000/mm³ increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm³ is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.

2. A client with heart failure is receiving a continuous IV infusion of milrinone. Which of the following actions should the nurse take?

• A. Monitor the client's blood pressure continuously
• B. Weigh the client daily
• C. Monitor the infusion site for signs of infiltration
• D. Measure the client's intake and output every 2 hours

Correct answer: D

Rationale: Measuring the client's intake and output every 2 hours is essential when caring for a client receiving a continuous IV infusion of milrinone. Milrinone is a medication that affects fluid balance, and monitoring intake and output helps assess the client's response to the medication. Continuous monitoring of blood pressure may not be necessary unless there is a specific indication. While weighing the client daily is important for overall assessment, measuring intake and output more frequently provides more real-time data for fluid balance evaluation. Monitoring the infusion site is crucial for detecting infiltration but is not directly related to managing fluid balance in this situation.

3. What is the most important nursing action for a patient presenting with confusion after surgery?

• A. Administer oxygen
• B. Reposition the patient
• C. Administer IV fluids
• D. Perform a neurological assessment

Correct answer: A

Rationale: Administering oxygen is crucial for a patient presenting with confusion after surgery because it helps alleviate potential hypoxia, which can be a common cause of confusion in the postoperative period. While repositioning the patient, administering IV fluids, and performing a neurological assessment are important nursing interventions in certain situations, addressing hypoxia by administering oxygen takes priority in this case to ensure an adequate oxygen supply to the brain and other vital organs.

4. A nurse is preparing to administer a unit of packed RBCs to a client. Which of the following actions should the nurse take first?

• A. Check the client's identification band
• B. Verify the provider's prescription
• C. Prime the IV tubing with 0.9% sodium chloride
• D. Obtain the client's vital signs

Correct answer: A

Rationale: The correct first action for the nurse to take when preparing to administer a unit of packed RBCs is to check the client's identification band. This step is crucial to ensure that the correct blood is administered to the right client, preventing any errors or adverse reactions. Verifying the provider's prescription, priming the IV tubing, and obtaining the client's vital signs are important steps in the process but should follow the initial identification check to prioritize patient safety.

5. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?

• A. Serum glucose level.
• B. Serum calcium level.
• C. Lymphocyte count.
• D. Serum potassium level.

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.
