Question 1 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.

Question 2 of 5

A client has a new prescription for zolpidem, a hypnotic. The client tells the home health nurse that he plans to take a dose of the medication during the day because he is exhausted and needs to take a short afternoon nap prior to an evening activity in his home. Which action should the nurse take?

Correct Answer: A

Rationale: Zolpidem should be taken at bedtime (
A) to avoid daytime drowsiness and fall risk (matches 55-Q4). Fluids (
B) are unrelated. Noon meal dosing (
C) reduces efficacy. Two hours (
D) is insufficient for clearance.

Question 3 of 5

A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?

Correct Answer: C

Rationale: Leafy greens, high in vitamin K, reduce warfarin’s anticoagulant effect (
C) (matches 55-Q46). Informing the provider ensures dose adjustment. Substituting vegetables (
A) is unnecessary. Praising (
B) or claiming enhanced efficacy (
D) ignores the interaction.

Question 4 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 (

Question 5 of 5

A client receives a prescription for dalteparin 2500 units subcutaneously 2 hours before a scheduled procedure. The medication is available in a 5000 units/0.2 mL prefilled syringe. How many mL should the nurse administer? (Enter Calculation(ans only) value only)

Correct Answer: 0.1
