1. A patient with congestive heart failure is prescribed furosemide 40 mg IV twice a day. The

medication label reads 10 mg/mL. How many mL of furosemide should the nurse administer per

dose?

A) 2 mL

B) 4 mL*

C) 8 mL

D) 10 mL

Rationale: To find the volume of medication to administer, use the formula V = D/C, where V is

volume, D is dose, and C is concentration. Plug in the values: V = 40 mg / 10 mg/mL = 4 mL.

2. A patient with diabetes mellitus is prescribed regular insulin 12 units subcutaneously before

breakfast. The insulin syringe has a concentration of 100 units/mL. How many mL of insulin should the

nurse draw up?

A) 0.08 mL

B) 0.12 mL*

C) 0.18 mL

D) 0.24 mL

Rationale: To find the volume of insulin to draw up, divide the dose by the concentration: 12 units /

100 units/mL = 0.12 mL.

3. A patient with hypertension is prescribed metoprolol 50 mg PO twice a day. The pharmacy

dispenses metoprolol 25 mg tablets. How many tablets should the nurse administer per dose?

A) 1 tablet

B) 2 tablets*

C) 3 tablets

D) 4 tablets

Rationale: To find the number of tablets to administer, divide the dose by the strength of each tablet:

50 mg / 25 mg = 2 tablets.

4. A patient with chronic kidney disease is prescribed epoetin alfa 150 units/kg subcutaneously three

times a week. The patient weighs 60 kg. The medication vial contains 2000 units/mL. How many mL of

epoetin alfa should the nurse administer per dose?

A) 0.45 mL*

B) 0.75 mL

C) 1.5 mL

D) 2.25 mL

Rationale: To find the volume of medication to administer, first calculate the dose in units by

multiplying the dose per kg by the patient's weight: 150 units/kg x 60 kg = 9000 units. Then, divide the

dose by the concentration: 9000 units / 2000 units/mL = 0.45 mL.

5. A patient with schizophrenia is prescribed haloperidol decanoate 100 mg IM every four weeks. The

medication vial contains a concentration of 50 mg/mL. How many mL of haloperidol decanoate

should the nurse administer per dose?

A) 1 mL
