Question 1 of 5
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective?
Correct Answer: C
Rationale: Epoetin alfa stimulates red blood cell production. A hemoglobin of 12 g/dL (
C) is the most objective indicator of efficacy. Iron therapy (
A), energy levels (
B), and diet (
D) are supportive but less definitive.
Question 2 of 5
An older adult with iron deficiency anemia is being discharged with a prescription for ferrous sulfate enteric-coated tablets. To promote best absorption of the medication, which information should the nurse include in the discharge instructions?
Correct Answer: A
Rationale: Ferrous sulfate is best absorbed on an empty stomach, 2 hours after meals (
A) (matches 55-Q13). Bedtime dosing (
B) isn’t specific. Multivitamins (
C) may reduce absorption. Crushing enteric-coated tablets (
D) disrupts their coating.

Correct Answer: B,C,E
Rationale: Ciprofloxacin requires reporting tendon pain (
B) due to rupture risk, high fluid intake (

Question 4 of 5
Prior to administering the evening dose of carbamazepine, the nurse notes that the client's morning carbamazepine level was 8.4 mg/L (35.6 mcmol/L). Which action should the nurse take?
Correct Answer: B
Rationale: Carbamazepine’s therapeutic range is 4-12 mg/L; 8.4 mg/L (
B) is therapeutic, so administer as prescribed (matches 55-Q23, but 55-Q23 had 84 mg/L, likely a typo). Notifying (
A) or withholding (
D) is unnecessary. Assessing side effects (
C) is routine but not specific.

The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective?
Correct Answer: C
Rationale: Sodium polystyrene sulfonate treats hyperkalemia. A potassium level of 3.8 mEq/L (
