How do you calculate the IV flow rate in ml/hour for a pediatric patient?

A. IV flow rate (ml/hour) = Volume to be infused (ml) + Time (hours)

B. IV flow rate (ml/hour) = Volume to be infused (ml) * Time (hours)

C. IV flow rate (ml/hour) = Volume to be infused (ml) / Time (hours)

A. 0.01 mg

B. 7 mg

C. 0.7 mg

D. 70 mg

What is the formula for calculating the dosage of a medication based on the patient’s weight?

A. Dosage = Weight (in g) x Dosage Factor

B. Dosage = Weight (in lbs) x Dosage Factor

C. Dosage = Weight (in cm) x Dosage Factor

D. Dosage = Weight (in kg) x Dosage Factor

A. 29.41 mg

B. 75 mg

C. 50 mg

D. 120 mg

If the adult dose of a medication is 200 mg, the child is 4 years old, and weighs 16 kg, what would be the pediatric dose using Clark’s rule?

A. Pediatric dose = (20 kg / 70) * 200 mg = 57.14 mg

B. Pediatric dose = (16 kg / 70) * 200 mg = 45.71 mg

C. Pediatric dose = (16 kg / 50) * 200 mg = 64 mg

D. Pediatric dose = (16 kg / 70) * 150 mg = 34.29 mg

What is the formula for calculating medication administration based on the volume to be administered and the concentration of the medication?

A. Dose = Volume + Concentration

B. Dose = Volume – Concentration

C. Dose = Volume / Concentration

D. Dose = Volume x Concentration

What is the formula for calculating pediatric dosage based on the child’s body surface area and the adult dose?

A. Pediatric Dose = (Child’s BSA / 1.73) * Adult Dose

B. Pediatric Dose = (Child’s BSA * 1.73) / Adult Dose

C. Pediatric Dose = (Child’s BSA – 1.73) / Adult Dose

D. Pediatric Dose = (Child’s BSA + 1.73) * Adult Dose

What is the formula for calculating the pediatric dosage of a medication based on the child’s weight and the prescribed dose per kg?

A. Pediatric dose = (Child’s weight in g) x (Prescribed dose per kg)

B. Pediatric dose = (Child’s age in years) x (Prescribed dose per kg)

C. Pediatric dose = (Child’s weight in kg) x (Prescribed dose per kg)

D. Pediatric dose = (Child’s weight in lbs) x (Prescribed dose per kg)

How do you calculate the IV flow rate in drops per minute?

A. IV flow rate (gtts/min) = (Volume to be infused in ml) / (drop factor in gtts/ml) x (Time in minutes)

B. IV flow rate (gtts/min) = (Volume to be infused in ml) + (drop factor in gtts/ml) – (Time in minutes)

C. IV flow rate (gtts/min) = (Volume to be infused in ml) x (drop factor in gtts/ml) / (Time in minutes)

D. IV flow rate (gtts/min) = (Volume to be infused in ml) x (drop factor in gtts/ml) / (Time in seconds)

Calculate the pediatric dosage of a medication if the prescribed dose is 0.2 mg/kg and the child weighs 25 kg.

A. 0.5 mg

B. 10 mg

C. 5 mg

D. 2.5 mg

What is the formula for calculating pediatric dosage based on the child’s age and weight and the adult dose?

A. Pediatric Dose = (Child’s Age in years / (Child’s Age in years + 10)) * Adult Dose + (Child’s Weight in kg / 30) * Adult Dose

B. Pediatric Dose = (Child’s Age in years / (Child’s Age in years + 15)) * Adult Dose + (Child’s Weight in kg / 50) * Adult Dose

C. Pediatric Dose = (Child’s Age in years / (Child’s Age in years + 12)) * Adult Dose + (Child’s Weight in kg / 40) * Adult Dose

D. Pediatric Dose = (Child’s Age in years / (Child’s Age in years + 8)) * Adult Dose + (Child’s Weight in kg / 35) * Adult Dose

If the prescribed IV fluid for a pediatric patient is 500 ml over 8 hours, what would be the IV flow rate in ml/hour?

If the adult dose of a medication is 150 mg and the child’s body surface area is 0.8 m², what would be the pediatric dose using the body surface area method?

A. Pediatric Dose = 150 mg × (0.8 ÷ 2) ≈ 60 mg

B. Pediatric Dose = 150 mg × (0.8 ÷ 1) ≈ 120 mg

C. Pediatric Dose = 150 mg × (0.8 ÷ 1.73) ≈ 69.36 mg

D. Pediatric Dose = 150 mg × (0.8 ÷ 1.5) ≈ 64 mg
