A client who weighs 176 pounds receives a prescription for filgrastim 5 mcg/kg/daily subcutaneously for 14 days. The medication is available in 300 mcg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.3"]
Given:
Ordered dose of Filgrastim: 5 mcg/kg/daily
Patient weight: 176 pounds
Concentration of Filgrastim: 300 mcg/mL
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 176 lbs x 0.453592 kg/lb = 79.832 kg
Step 2: Calculate the total daily dose of Filgrastim:
Total daily dose (mcg) = Ordered dose (mcg/kg/daily) x Patient weight (kg)
Total daily dose (mcg) = 5 mcg/kg/daily x 79.832 kg
Total daily dose (mcg) = 399.16 mcg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total daily dose (mcg) / Concentration (mcg/mL)
Volume (mL) = 399.16 mcg / 300 mcg/mL
Volume (mL) = 1.3305 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 1.3 mL

Correct Answer is ["60"]
Explanation
Given:
Ordered dose: 25 mL PO every 6 hours PRN
Medication label: "Acetaminophen and Codeine Phosphate Oral Solution, USP: 120/12 mg per 5 mL"
Step 1: Determine the concentration of codeine in the solution:
Concentration of Codeine = Amount of Codeine / Volume of Solution
Concentration of Codeine = 12 mg / 5 mL
Concentration of Codeine = 2.4 mg/mL
Step 2: Calculate the amount of codeine per dose:
Amount of Codeine per Dose = Concentration of Codeine x Volume per Dose
Amount of Codeine per Dose = 2.4 mg/mL x 25 mL
Amount of Codeine per Dose = 60 mg
Correct Answer is ["400"]
Explanation
Given:
Volume of fluid: 1000 mL
Infusion time: 2.5 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 1000 mL / 2.5 hr
Flow rate (mL/hr) = 400 mL/hr
