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. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?

• A. Reposition the nasal cannula
• B. Lower the oxygen rate
• C. Encourage the client to cough and deep breathe
• D. Monitor the client's oxygen saturation level

Correct answer: B

Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.

3. The nurse is evaluating the health status of an older client. Which finding is most important for the nurse to report to the healthcare provider?

• A. Client reports decreased urine output
• B. Client reports loss of appetite
• C. Client reports pain in the lower back
• D. Client reports a persistent cough

Correct answer: C

Rationale: Pain in the lower back is a significant finding in an older client as it can indicate underlying issues such as kidney problems, spinal issues, or even aortic aneurysm. These conditions can be serious and require prompt medical attention. Decreased urine output (choice A) could indicate dehydration or kidney issues but is not as urgent as lower back pain. Loss of appetite (choice B) may be concerning but is not as critical as the potential life-threatening conditions associated with lower back pain. A persistent cough (choice D) is important to assess but is generally not as urgent as the potential serious implications of lower back pain in an older client.

4. A male client with diabetes mellitus takes Novolin 70/30 insulin before meals and azithromycin (Zithromax) PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of the Zithromax an hour before breakfast as instructed. What action should the nurse implement?

• A. Offer to obtain a new breakfast tray in an hour so the client can take the Zithromax
• B. Instruct the client to eat his breakfast and take the Zithromax two hours after eating
• C. Tell the client to skip that day's dose and resume taking the Zithromax the next day
• D. Provide a PRN dose of an antacid to take with the Zithromax right after breakfast

Correct answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.

5. A client with a small bowel obstruction is experiencing frequent vomiting. Which instructions are most important for the nurse to provide to the unlicensed assistive personnel (UAP) who is completing morning care for this client?

• A. Maintain a quiet environment
• B. Ensure the linens are clean and dry
• C. Place an air deodorizer in the room
• D. Measure all emesis accurately

Correct answer: D

Rationale: The correct answer is D, 'Measure all emesis accurately.' When a client with a small bowel obstruction is experiencing frequent vomiting, measuring emesis accurately is crucial for monitoring fluid balance and preventing dehydration. Choice A, 'Maintain a quiet environment,' while important for patient comfort, is not as critical as accurately measuring emesis. Choices B and C, 'Ensure the linens are clean and dry' and 'Place an air deodorizer in the room,' focus on environmental factors that, although helpful, are not as essential as monitoring the client's fluid balance in this situation.
