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)
What is the formula for calculating pediatric dosage based on the child’s age and the adult dose?
A. Pediatric Dose = (Age in years – 5) * Adult Dose

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)
D. IV flow rate (ml/hour) = Volume to be infused (ml) – Time (hours)
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)
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
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?
A. 250 ml/hour
B. 100 ml/hour
C. 62.5 ml/hour
D. 375 ml/hour
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 IV infusion set delivers 15 drops per ml, and the prescribed IV flow rate is 60 ml/hour, how many drops per minute should be administered?
A. 30 drops/minute
B. 15 drops/minute
C. 20 drops/minute
D. 45 drops/minute

B. 7 mg
C. 0.7 mg
D. 70 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
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
