# SECTION 1: BASIC DOSAGE CALCULATIONS (ORAL &
PARENTERAL)## (Questions 1–25)
---
**1.** A physician orders amoxicillin 500 mg PO q8h. The available
medication is amoxicillin 250 mg tablets. How many tablets should the
nurse administer per dose?
A) 0.5 tablet
B) 1 tablet
C) 2 tablets
D) 2.5 tablets
**Answer:** C) 2 tablets
**Rationale:** Formula: Desired dose ÷ Available dose = Tablets per

measurement matches (both in mg).

**2.** Order: Digoxin 0.125 mg PO daily. Available: Digoxin 0.25 mg
tablets. How many tablets should the nurse administer?
A) 0.25 tablet
B) 0.5 tablet
C) 1 tablet
D) 2 tablets
**Answer:** B) 0.5 tablet
**Rationale:** 0.125 mg ÷ 0.25 mg = 0.5 tablet. Always verify that
scored tablets can be split safely; digoxin tablets are scored and can be
divided.
---
**3.** A patient is prescribed furosemide 40 mg IV push. The vial
contains furosemide 10 mg/mL. How many mL should the nurse
administer?
A) 2 mL
B) 3 mL
C) 4 mL
, 4|Page
D) 5 mL
**Answer:** C) 4 mL
**Rationale:** 40 mg ÷ 10 mg/mL = 4 mL. IV push furosemide should
be administered slowly at a rate not exceeding 20 mg/min to prevent
ototoxicity.
---
**4.** Order: Morphine sulfate 8 mg IM q4h PRN pain. Available:
Morphine sulfate 10 mg/mL. How many mL should the nurse
administer?
A) 0.8 mL
B) 1 mL
C) 1.2 mL
D) 1.25 mL
**Answer:** A) 0.8 mL
**Rationale:** 8 mg ÷ 10 mg/mL = 0.8 mL. Always round to the nearest
tenth for injectable medications unless using a tuberculin syringe for
volumes <1 mL.
