The nurse is caring for a client who has chronic renal disease and is receiving therapy with erythropoietin (epoetin alpha). Which of the following laboratory results should the nurse review as an indication of a therapeutic effect of this medication?
Leukocytes
Hemoglobin
Platelets
Brain Natriuretic peptide
The Correct Answer is B
A. Leukocytes: Erythropoietin does not affect white blood cell (WBC) production.
B. Hemoglobin: Erythropoietin stimulates red blood cell (RBC) production in the bone marrow. Clients with chronic kidney disease (CKD) develop anemia due to decreased natural erythropoietin production. A therapeutic response is seen as an increase in hemoglobin levels.
C. Platelets: Erythropoietin does not stimulate platelet production (thrombopoiesis).
D. Brain Natriuretic Peptide (BNP): BNP is a marker for heart failure, not erythropoiesis.

Correct Answer is B
Explanation
A. Serum potassium 4.8 mmol/L: This is a normal potassium level (3.5–5.0 mmol/L) and indicates successful treatment.
B. Serum glucose 58 mg/dL: IV insulin drives potassium into cells, lowering serum potassium. However, insulin also lowers blood glucose, which can lead to hypoglycemia (glucose <70 mg/dL). Hypoglycemia is the primary adverse effect of IV insulin therapy.
C. Serum sodium 138 mEq/L: This is a normal sodium level (135–145 mEq/L) and not an adverse effect.
D. Calcium level of 100 mg: Calcium is not directly affected by IV insulin therapy.
Correct Answer is ["1370"]
Explanation
To calculate total output, we sum all recorded outputs:
- Urine output:
- 400 mL + 350 mL = 750 mL
- Chest tube drainage:
- 175 mL (current) - 155 mL (previous) = 20 mL
- Nasogastric tube drainage: 575 mL
- Jackson-Pratt drain output: 25 mL
Total Output = 750 + 20 + 575 + 25 = 1,370 mL
Correct Answer: 1,370 mL
