(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.85"]
The healthcare provider prescribes lorazepam at a dose of 50 mcg/kg intramuscularly 2 hours before a scheduled procedure for a client who weighs 74 kg.
The client should receive 3700 mcg of lorazepam (50 mcg/kg * 74 kg). Since 1 mg is equivalent to 1000 mcg, 3700 mcg is equivalent to 3.7 mg.
The medication is available in a 2 mg/mL vial, so the nurse should administer 1.85 mL of medication (3.7 mg / 2 mg/mL).

Correct Answer is ["2"]
Explanation
The bottle is labeled "Ibuprofen for Oral Suspension, USP 100 mg per 5 mL." This means that for every 5 mL (or 1 teaspoon) of the suspension, there is 100 mg of ibuprofen.
To administer a dose of 200 mg, the parent should give the child 2 teaspoons (10 mL) of the suspension.
Correct Answer is ["2.4"]
Explanation
Step 1 is to identify the ordered dose and the correct available concentration based on the route of administration.
Ordered Dose: 4,780 IU
Route: IV (Intravenous)
Available Strength: 10,000 IU
Reconstitution Volume for IV: 5 mL
Step 2 is to calculate the volume to administer in milliliters (mL)
Volume = (Ordered Dose ÷ Available Dose) × Available Volume
Volume = (4,780 ÷ 10,000) × 5
4,780 ÷ 10,000 = 0.478
0.478 × 5 = 2.39
Volume to administer = 2.39 mL
Step 3 is to round to the nearest tenth
2.39 rounds to 2.4
Answer: 2.4
