Answer and Explanation

The Correct Answer is ["0.2"]

Given:

Ordered dose of Atropine Sulfate: 0.01 mg/kg

Child's weight: 44 pounds

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg

Step 2: Calculate the total dose of Atropine Sulfate:

Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)

Total dose (mg) = 0.01 mg/kg x 19.958 kg

Total dose (mg) = 0.19958 mg

Step 3: Round to the nearest tenth:

Total dose (mg) ≈ 0.2 mg

Explanation

Given:

Ordered loading dose of Heparin: 80 units/kg

Patient weight: 96 kg

Step 1: Calculate the total loading dose of Heparin:

Total loading dose (units) = 80 units/kg x 96 kg

Total loading dose (units) = 7680 units

Correct Answer is ["1.3"]

Explanation

Given:

Ordered dose of amoxicillin: 25 mg/kg/day

Child's weight: 18 pounds

Concentration of amoxicillin suspension: 400 mg/5 mL

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 18 lbs x 0.453592 kg/lb = 8.164656 kg

Step 2: Calculate the total daily dose of amoxicillin:

Total daily dose (mg) = Ordered dose (mg/kg/day) x Child's weight (kg)

Total daily dose (mg) = 25 mg/kg/day x 8.164656 kg

Total daily dose (mg) = 204.1164 mg/day

Step 3: Calculate the dose per administration:

Since the medication is given every 12 hours, there are 2 administrations per day.

Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day

Dose per administration (mg) = 204.1164 mg/day / 2 administrations/day

Dose per administration (mg) = 102.0582 mg

Step 4: Calculate the volume to be administered per dose:

Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)

Volume (mL) = 102.0582 mg / (400 mg/5 mL)

Volume (mL) = 102.0582 mg x (5 mL / 400 mg)

Volume (mL) = 1.2757275 mL

Step 5: Round to the nearest tenth:

Volume (mL) ≈ 1.3 mL
