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 planning care for a client receiving chemotherapy. Which intervention should the nurse include to manage the client's nausea?

• A. Administer an antiemetic before meals
• B. Provide frequent mouth care
• C. Encourage small, frequent meals
• D. Offer clear liquids

Correct answer: A

Rationale: Administering an antiemetic before meals is a crucial intervention to manage chemotherapy-induced nausea. Antiemetics help prevent or reduce nausea and vomiting associated with chemotherapy. Providing frequent mouth care (choice B) is important for managing oral mucositis but not specifically for nausea. Encouraging small, frequent meals (choice C) and offering clear liquids (choice D) are beneficial strategies for managing gastrointestinal side effects but may not be as effective in controlling nausea as administering antiemetics.

3. Several clients on a telemetry unit are scheduled for discharge in the morning, but a telemetry-monitored bed is needed immediately. The charge nurse should make arrangements to transfer which client to another medical unit?

• A. Learning to self-administer insulin injections after being diagnosed with diabetes mellitus
• B. Ambulatory following coronary artery bypass graft surgery performed six days ago
• C. Wearing a sling immobilizer following permanent pacemaker insertion earlier that day
• D. Experiencing syncopal episodes resulting from the dehydration caused by severe diarrhea

Correct answer: A

Rationale: The correct answer is A because transferring a stable client who is learning self-care, such as self-administering insulin injections after being diagnosed with diabetes mellitus, provides the needed telemetry-monitored bed without compromising the client's care. Choice B should not be transferred as the client is ambulatory following surgery and does not require telemetry monitoring. Choice C should not be transferred as the client is wearing a sling immobilizer following pacemaker insertion, which requires close monitoring. Choice D should not be transferred as the client is experiencing syncopal episodes due to severe dehydration, necessitating telemetry monitoring for immediate intervention.

4. The nurse is triaging clients from a train wreck. A client has multiple open wounds, a blood pressure of 90/56, and a pulse of 112 beats/minute. Which triage tag color should the nurse place on this client?

• A. Black
• B. Yellow
• C. Green
• D. Red

Correct answer: D

Rationale: The correct answer is D: Red. The client's vital signs indicate critical condition with a high pulse and low blood pressure, suggesting shock. A red tag is used to identify patients who require immediate attention and should be prioritized for treatment. Choice A, Black, is incorrect as it is typically used for deceased or expectant clients. Choice B, Yellow, is used for clients with non-life-threatening injuries who require medical care but can wait. Choice C, Green, is for clients with minor injuries who can wait the longest for treatment. Therefore, in this scenario, the client's condition warrants a red triage tag for immediate attention.

5. The nurse is assessing a client who has a prescription for digoxin (Lanoxin). Which finding indicates that the client is at risk for digoxin toxicity?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 120/80 mm Hg
• C. Respiratory rate of 18 breaths per minute
• D. Serum potassium level of 3.0 mEq/L

Correct answer: D

Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.
