Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse is caring for a client who is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump. Which action is most important for the nurse to implement?

• A. Monitor the client's respiratory status
• B. Teach the client how to use the PCA pump
• C. Evaluate the client's pain level
• D. Assess the client's pain level

Correct answer: A

Rationale: The correct answer is to monitor the client's respiratory status. When administering opioids like morphine sulfate via a PCA pump, it is crucial to closely monitor the client's respiratory status to detect signs of respiratory depression early. This is important for ensuring the client's safety while receiving pain management. Choices B, C, and D are incorrect because while teaching the client to use the PCA pump and assessing or evaluating their pain level are essential aspects of care, monitoring respiratory status takes precedence due to the potential risks associated with opioid use.

3. 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.

4. In the newborn nursery, the nurse admits a baby from labor and delivery who is suspected of having a congenital heart disease. Which finding helps to confirm this diagnosis?

• A. Pink lips and tongue with cyanotic hands and feet
• B. Respiration rate of 40 and heart rate of 144
• C. Centralized cyanosis and tachycardia when crying
• D. Desquamation from areas of cracked, parchment-like skin

Correct answer: C

Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.

5. The nurse is caring for a client with a diagnosis of pneumonia who has been febrile for 24 hours. Which data is most important for the nurse to obtain in determining the client's fluid status?

• A. Daily intake and output
• B. Skin turgor
• C. Daily weight
• D. Vital signs every 4 hours

Correct answer: C

Rationale: Daily weight is the most important data for the nurse to obtain in determining the client's fluid status in this scenario. During febrile episodes, assessing daily weight is crucial as it can indicate fluid retention or loss. While monitoring intake and output is important for assessing fluid balance, daily weight provides a more comprehensive picture of fluid status over time. Skin turgor is more indicative of hydration status than overall fluid status, and vital signs, although essential, do not directly assess fluid status as effectively as daily weight.
