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 assessing on the first postoperative day following thyroid surgery. Which laboratory value is most important for the nurse to monitor?

• A. Calcium
• B. Sodium
• C. Chloride
• D. Potassium

Correct answer: A

Rationale: Corrected Rationale: Monitoring calcium levels is crucial post-thyroid surgery to detect hypocalcemia, a common complication due to injury or removal of the parathyroid glands. Monitoring sodium, chloride, or potassium levels is not as vital in the immediate post-thyroid surgery period.

3. 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.

4. A client who is 32-weeks pregnant is diagnosed with partial placenta previa. Which instruction should the nurse include in this client’s teaching plan?

• A. Wear a tight abdominal binder at all times
• B. Take a daily laxative to prevent constipation
• C. Refrain from sexual intercourse until your next appointment
• D. Restrict fluids to less than 1000 ml per day

Correct answer: C

Rationale: Refraining from sexual intercourse helps prevent complications with partial placenta previa.

5. A client is receiving a low dose of dopamine (Intropin) IV for the treatment of hypotension. Which indicator reflects that the medication is having the desired effect?

• A. Increased heart rate
• B. Increased urinary output
• C. Increased blood pressure
• D. Increased respiratory rate

Correct answer: C

Rationale: Increased blood pressure is the desired effect of administering dopamine (Intropin) to treat hypotension. Dopamine acts by stimulating adrenergic receptors, leading to vasoconstriction and increased cardiac output. This results in an elevation of blood pressure. Choices A, B, and D are incorrect as they do not directly reflect the therapeutic action of dopamine in treating hypotension. Increased heart rate may indicate the body compensating for low blood pressure, increased urinary output is more related to kidney function, and increased respiratory rate is often seen in response to respiratory issues, not the action of dopamine on hypotension.
