Nursing Elites

1. A client with acute kidney injury (AKI) weighing 50kg and having a potassium level of 6.7mEq/L (6.7mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

• A. Calcium acetate, one tablet by mouth
• B. Sodium polystyrene sulfonate, 15 grams by mouth
• C. Epoetin Alfa, recombinant, 2,500 units subcutaneously
• D. Sevelamer, one tablet by mouth

Correct answer: B

Rationale: In a client with acute kidney injury (AKI) and hyperkalemia, the priority intervention is to lower the potassium level swiftly. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, reducing the overall potassium levels. Calcium acetate, epoetin alfa, and sevelamer are not indicated for the immediate reduction of potassium levels in hyperkalemia. Calcium acetate is used to control phosphate levels, epoetin alfa is a medication to treat anemia by stimulating red blood cell production, and sevelamer is a phosphate binder used in chronic kidney disease to reduce phosphate levels.

2. The healthcare provider is assessing a client with chronic renal failure who is receiving hemodialysis. Which of the following findings would indicate that the client is experiencing a complication of the treatment?

• A. Clear dialysate outflow.
• B. Blood pressure of 150/90 mm Hg.
• C. Increased heart rate.
• D. Fatigue.

Correct answer: B

Rationale: A blood pressure of 150/90 mm Hg during hemodialysis may indicate fluid overload or an ineffective dialysis session, which can lead to complications such as heart failure or pulmonary edema. This finding should be reported promptly for further evaluation and intervention. Clear dialysate outflow is a normal and expected finding during hemodialysis, indicating proper filtration of waste products. Increased heart rate can be a normal compensatory response to hemodialysis due to fluid shifts and should be monitored but does not necessarily indicate a complication. Fatigue is a common symptom in clients with chronic renal failure undergoing hemodialysis and is not specific to complications of the treatment.

3. A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?

• A. Hemoglobin
• B. Serum bilirubin
• C. Blood urea nitrogen (BUN)
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.

4. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?

• A. Hyponatremia.
• B. Hypokalemia.
• C. Hyperkalemia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.

5. In a patient with chronic kidney disease, which of the following lab values would be expected?

• A. Elevated creatinine levels.
• B. Low hemoglobin levels.
• C. Elevated potassium levels.
• D. Low sodium levels.

Correct answer: A

Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.
