Answer and Explanation

The Correct Answer is ["1.3"]

Calculation:

Formula:

Volume to administer (mL) = Desired dose (units) / Available concentration (units/mL)

Desired dose = 650,000 units

Available concentration = 500,000 units/mL

Volume to administer (mL) = Desired dose (units) / Available concentration (units/mL)

= 650,000 units / 500,000 units/mL

= 1.3 mL

Correct Answer is ["300"]

Explanation

Calculate the total volume to be infused over 8 hours:

Total volume infused (mL) = Infusion rate (mL/hour) x Infusion time (hours)

= 75 mL/hour x 8 hours

= 600 mL

Calculate the remaining volume in the IV bag after 8 hours:

Remaining volume (mL) = Initial volume (mL) - Total volume infused (mL)

= 900 mL - 600 mL

= 300 mL

Correct Answer is ["1.2"]

Explanation

Convert the client's weight from pounds to kilograms:

Weight (kg) = Weight (pounds) / 2.2 pounds/kg

= 132 pounds / 2.2 pounds/kg

= 60 kg

Calculate the dose per administration:

Dose per administration (mg) = Prescribed dose (mg/kg) x Client's weight (kg)

= 1 mg/kg x 60 kg

= 60 mg

Determine the volume to administer per dose:

Volume per dose (mL) = Desired dose (mg) / Available concentration (mg/mL)

= 60 mg / (60 mg / 0.6 mL)

= 0.6 mL

Calculate the total volume to administer per day:

Number of administrations per day = every 12 hours means 24 hours / 12 hours/administration

= 2 administrations

Total daily volume (mL) = Volume per dose (mL) x Number of administrations per day

= 0.6 mL/dose x 2 doses/day

= 1.2 mL/day
