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 discharge teaching for a client with chronic kidney disease. Which information is most important for the nurse to provide this client?

• A. Monitor daily weights
• B. Limit fluid intake to prevent fluid overload
• C. Report any weight gain of more than 2 pounds in a day
• D. Increase protein intake to promote healing

Correct answer: C

Rationale: The most important information for the nurse to provide a client with chronic kidney disease is to report any weight gain of more than 2 pounds in a day. This is crucial because sudden weight gain can indicate fluid retention, which is a common issue in kidney disease. Monitoring daily weights, as in option A, is important but not as critical as reporting sudden weight gain. Option B, limiting fluid intake, is a general recommendation for kidney disease but not the most important aspect in this scenario. Option D, increasing protein intake, is not appropriate as excessive protein intake can be harmful for clients with kidney disease.

3. The nurse enters the room of a client with a nasogastric tube who is receiving continuous feeding. The nurse observes that the client is coughing and that the infusion pump is alarming. What action should the nurse take first?

• A. Auscultate the client's breath sounds
• B. Turn the client to the side
• C. Stop the feeding infusion
• D. Notify the healthcare provider

Correct answer: C

Rationale: The correct action for the nurse to take first in this situation is to stop the feeding infusion. Coughing in a client with a nasogastric tube can indicate aspiration, which can be a serious complication. By stopping the feeding infusion immediately, the nurse can prevent further aspiration and related complications. Auscultating breath sounds or turning the client to the side may be necessary actions but addressing the feeding infusion is the priority. Notifying the healthcare provider can be done after the immediate issue of potential aspiration is managed.

4. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, 'I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home'. What response is best for the nurse to provide?

• A. Heparin prevents future clot formation, but your risk of bleeding needs to be monitored closely
• B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
• C. Let me contact your surgeon and find out if Heparin IV therapy can be administered to you at home
• D. Why are you so anxious to leave the hospital when you know you are not well enough yet?

Correct answer: A

Rationale: Choice A is the best response because it educates the client about the role of heparin in preventing future clot formation rather than dissolving the existing clot. This helps the client understand the medication's function and the importance of closely monitoring for signs of bleeding, a common side effect of heparin therapy. Choice B acknowledges the client's concern but does not provide accurate information about heparin's mechanism of action. Choice C is premature as it suggests transitioning to home therapy without addressing the client's concerns or explaining heparin's purpose. Choice D does not address the client's statement and instead questions their desire to leave the hospital.

5. 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.
