Dosage by weight for a child notes

What is the formula for pediatric dosage?

Pediatric dosage = (Child's weight in kg / 70 kg) x Adult dosage

How do you convert pounds to kilograms?

To convert pounds to kilograms, divide by 2.2. Example: 44 lbs = 20 kg.

True or false: Dosage is the same for all children.

False, because dosages vary based on weight and age.

Difference between mg/kg and mg/m²?

mg/kg is per kilogram of body weight; mg/m² is per square meter of body surface area.

Calculate the dosage: 10 mg/kg for a 15 kg child.

Dosage = 10 mg/kg x 15 kg = 150 mg.

What is body surface area (BSA)?

BSA is an estimate of the total surface area of the body, used for drug dosing.

Fill in the blank: The average weight of a child is ___ lbs.

The average weight of a child is 40 lbs.

True or false: Weight-based dosing is only for IV medications.

False, because weight-based dosing applies to oral and other forms of medications too.

What does the term 'therapeutic range' mean?

The therapeutic range is the concentration range in which a drug is effective and safe.

Calculate the dosage: 5 mg/m² for a child with BSA of 1.5 m².

Dosage = 5 mg/m² x 1.5 m² = 7.5 mg.

Which weight unit is preferred for pediatric dosing?

Kilograms (kg) is the preferred unit for pediatric dosing.

True or false: You can use adult dosages for children.

False, because children require specific dosages based on their size.

What is the significance of weight-based dosing?

Weight-based dosing ensures children receive appropriate medication amounts based on their body size.

Calculate the weight in kg for a child weighing 50 lbs.

Weight in kg = 50 lbs / 2.2 = 22.73 kg.

Fill in the blank: The standard weight for dosage calculations is ___ kg.

The standard weight for dosage calculations is 70 kg.

How does age impact dosing?

Age affects metabolism and the effectiveness of medications, requiring adjusted dosages.
