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 nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?

• A. Heart rate of 50 beats per minute
• B. Blood pressure of 90/60 mm Hg
• C. Respiratory rate of 20 breaths per minute
• D. Temperature of 99°F (37.2°C)

Correct answer: A

Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.

3. The nurse is caring for a client who is 2 days post-op following an abdominal hysterectomy. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?

• A. Apply a sterile saline dressing to the wound
• B. Notify the healthcare provider
• C. Administer pain medication
• D. Cover the wound with an abdominal binder

Correct answer: A

Rationale: In this situation, the priority action for the nurse is to apply a sterile saline dressing to the wound. This helps to cover and protect the exposed bowel, preventing infection and maintaining a moist environment for wound healing. Option B, notifying the healthcare provider, is important but should come after addressing the immediate need of covering the wound. Administering pain medication (option C) and covering the wound with an abdominal binder (option D) are not appropriate initial actions for this situation.

4. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?

• A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
• B. Administer a retention enema of Kayexalate.
• C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
• D. Administer a lidocaine bolus IV push.

Correct answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

5. 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.
