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. 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.

3. A client who has a flaccid bladder is placed on a bladder training program. Which instruction should the nurse include in this client's teaching plan?

• A. Use manual pressure to express urine
• B. Perform the Crede maneuver
• C. Apply an external urinary drainage device
• D. Take a warm sitz bath twice a day

Correct answer: B

Rationale: The correct answer is B: Perform the Crede maneuver. The Crede maneuver is a technique used to manage a flaccid bladder by applying manual pressure over the bladder area to assist in the expulsion of urine. This technique helps promote bladder emptying. Choice A is incorrect because using manual pressure to express urine is not a standardized technique and may cause harm. Choice C is incorrect as applying an external urinary drainage device does not address the need for bladder training. Choice D is unrelated to bladder training for a flaccid bladder.

4. An angry client screams at the emergency department triage nurse, 'I've been waiting here for two hours! You and the staff are incompetent.' What is the best response for the nurse to make?

• A. The emergency department is very busy at this time.
• B. I'll let you see the doctor next because you've waited so long.
• C. I'm doing the best I can for the sickest clients first.
• D. I understand you are frustrated with the wait time.

Correct answer: D

Rationale: The correct response for the nurse is to choose option D, 'I understand you are frustrated with the wait time.' This response acknowledges the client's emotions, shows empathy, and validates their feelings of frustration. Option A justifies the situation but does not address the client's emotional state. Option B is unfair to other patients and may not be based on urgency. Option C focuses on the nurse's actions rather than addressing the client's emotions, making it less effective than option D.

5. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.
