Nursing Elites

1. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

2. A client with cervical cancer is hospitalized for insertion of a sealed internal cervical radiation implant. What action should the nurse take when finding the radiation implant in the bed?

• A. Call radiation therapy for assistance
• B. Place the implant in a lead container using long-handled forceps
• C. Leave the implant in the bed and notify the provider
• D. Dispose of the implant in the nearest sharps container

Correct answer: B

Rationale: The correct action for the nurse to take when finding the radiation implant in the bed is to use long-handled forceps to place the implant in a lead container. This procedure is crucial in reducing radiation exposure to both the patient and healthcare providers. Calling radiation therapy for assistance (Choice A) may delay the immediate need for safe handling of the implant. Leaving the implant in the bed and notifying the provider (Choice C) is unsafe and can lead to increased radiation exposure. Disposing of the implant in a sharps container (Choice D) is incorrect as the implant should be placed in a lead container, not a sharps container, to contain the radiation.

3. A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. White blood cell count.
• B. Hemoglobin level.
• C. Serum creatinine level.
• D. Platelet count.

Correct answer: B

Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.

4. The nurse is teaching a client about postoperative care following a total knee arthroplasty. What instruction should the nurse prioritize?

• A. Begin ambulation as soon as possible.
• B. Use continuous passive motion therapy to maintain joint mobility.
• C. Avoid putting weight on the affected leg.
• D. Apply ice packs to reduce pain and swelling.

Correct answer: B

Rationale: The correct answer is B: 'Use continuous passive motion therapy to maintain joint mobility.' Continuous passive motion therapy is crucial in postoperative care following a total knee arthroplasty as it helps prevent stiffness and maintain joint mobility. Ambulation is important but should be guided and not immediate. Avoiding putting weight on the affected leg is also essential initially to prevent complications. Applying ice packs can help reduce pain and swelling, but it is not the priority instruction for maintaining joint mobility and preventing stiffness.

5. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
