Below are sample questions from this exam to help you understand the content and format.
Q1: A nurse is preparing to administer a 100 mcg stat dose of fentanyl IV for a client with severe pain. The amount available is 0.05 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer Choices:
✔ Step 1: Convert micrograms (mcg) to milligrams (mg)
100 mcg ÷ 1000 = 0.1 mg
✔ Step 2: Use the formula to calculate mL
Available: 0.05 mg/mL
mL = Dose ÷ Concentration
mL = 0.1 ÷ 0.05 = 2
✔ Step 3: Rounding
Already a whole number = 2 mL
Q2: A nurse is documenting the Intake & Output on one of his clients for the last 12 hours. The client reported that he had 5 ounces of juice, 6 ounces of coffee, and 12 ounces of water and half an ounce of liquid medication. The client had a urine output of 420 mL and 1 episode of diarrhea. What will the nurse enter on the client's total intake (mL)? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer Choices:
✔ Step 1: Convert ounces to milliliters
1 oz = 30 mL
✔ Step 2: Add all intake volumes
Total intake = 150 + 180 + 360 + 15 = 705 mL
✔ Step 3: Rounding
Already a whole number = 705 mL
Q3: A nurse is preparing to administer lactulose 15 mL PO once daily. How many tablespoons should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer Choices:
✔ Step 1: Use the standard conversion factor
1 tablespoon (Tbsp) = 15 mL
✔ Step 2: Set up the formula
Tbsp = mL ÷ 15
Tbsp = 15 ÷ 15 = 1
✔ Step 3: Rounding
Already a whole number = 1 tablespoon
Q4: A nurse is preparing to administer 2.4 million units of penicillin G intramuscularly for a client who is both positive for HIV and syphilis. The prescriber ordered 2.4 million units 1M every week for three consecutive weeks. The available dose comes in a 600,000/mL vial. How many mL of medications would the client receive per dose?
Answer Choices:
✔ Step 1: Identify the prescribed dose and available concentration
Prescribed dose = 2,400,000 units
Available = 600,000 units/mL
✔ Step 2: Use the formula to calculate mL
mL = Dose ÷ Concentration
mL = 2,400,000 ÷ 600,000 = 4
✔ Step 3: Rounding
Already a whole number = 4 mL
Q5: A nurse is preparing to administer tramadol 100 mg PO every 6 hours for a client prior to wound dressing change. The amount available is 50 mg/tablet. How many tablet(s) should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer Choices:
✔ Step 1: Identify the prescribed dose and tablet strength
Prescribed dose = 100 mg
Available = 50 mg per tablet
✔ Step 2: Use the formula to calculate tablets
Tablets = Dose ÷ Strength per tablet
Tablets = 100 ÷ 50 = 2
✔ Step 3: Rounding
Already a whole number = 2 tablets
