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 C
Explanation
A. Administer scheduled medications: Some medications (e.g., antihypertensives, water-soluble vitamins, and antibiotics) should be held before dialysis to prevent removal during treatment.
B. Explain that dialysis occurs via the peritoneum: This describes peritoneal dialysis, not hemodialysis.
C. Weigh the client to determine a baseline for comparison: Pre-dialysis weight is crucial to determine fluid removal needs during dialysis. Weight differences before and after dialysis indicate fluid loss or retention.
D. Obtain a serum creatinine to determine kidney function: Serum creatinine levels are monitored regularly but are not a required step before every dialysis session.
Correct Answer is D
Explanation
A. Magnesium sulfate: Magnesium sulfate is used for eclampsia and torsades de pointes, not for reducing shivering.
B. Kayexalate: This medication is used for hyperkalemia, not temperature control.
C. Acetaminophen: While useful for fever, acetaminophen does not stop shivering.
D. Diazepam: Shivering increases metabolic demand and body temperature. Diazepam (a benzodiazepine) is a muscle relaxant that helps control shivering in hyperthermic clients.
