A nurse is reviewing the laboratory findings of a client who is taking erythropoietin. Which of the following results indicates the medication is effective?
Decreased white blood cells
Increased calcium
Increased hemoglobin
Decreased BUN
The Correct Answer is C
A. Decreased white blood cells: Erythropoietin specifically stimulates red blood cell production in the bone marrow. White blood cell counts are not directly affected by this medication, so a decrease would not indicate effectiveness.
B. Increased calcium: Calcium levels are unrelated to erythropoietin therapy. Changes in calcium do not reflect the medication’s ability to stimulate erythropoiesis.
C. Increased hemoglobin: Erythropoietin promotes red blood cell production, which increases hemoglobin and hematocrit levels. An elevation in hemoglobin indicates the medication is effectively stimulating erythropoiesis.
D. Decreased BUN: Blood urea nitrogen reflects kidney function and protein metabolism. While erythropoietin is often used in clients with chronic kidney disease, a decrease in BUN is not a direct measure of the drug’s effectiveness.

Correct Answer is D
Explanation
A. Document the updated list and send it to the pharmacy: Documentation occurs after all medications have been reviewed and discrepancies resolved. Completing this step first could result in incomple te or inaccurate records.
B. Compare preadmission medications to current medications: Comparison is done after compiling a comprehensive list of current medications. Without knowing exactly what the client is taking, discrepancies cannot be identified.
C. Address any discrepancies between current medications and new prescriptions: Resolving discrepancies comes after compiling and comparing medication lists. This ensures that interventions are based on accurate and complete information.
D. Compile a list of all medications the client is currently taking: The first step in medication reconciliation is gathering a complete and accurate list of all medications, including prescriptions, over-the-counter drugs, and supplements. This forms the foundation for safe comparison and management.
Correct Answer is C
Explanation
A. "I will limit my alcohol intake to two drinks per day.": Alcohol increases the risk of hepatotoxicity when combined with methotrexate. Clients should avoid alcohol completely rather than limiting intake.
B. "I should avoid eating foods that contain vitamin C.": Vitamin C does not worsen stomatitis or interact adversely with methotrexate. There is no need to avoid it in the diet.
C. "I should rinse my mouth with a warm salt solution.": Salt water rinses help soothe oral irritation, reduce bacterial growth, and promote healing of stomatitis, making this the appropriate action.
D. "I will continue to floss my teeth after each meal.": Flossing may irritate the oral mucosa further and worsen stomatitis, so clients should avoid it until the mucosa has healed.
