Mastering Body Surface Area Dosage Calculations in Pediatric Nursing

This video tutorial by Sarah Thread Sterner covers the calculation of body surface area (BSA) for accurate medication dosing, especially in pediatric and chemotherapy cases. It explains the use of metric and household formulas for BSA calculation, provides example problems, and discusses advanced scenarios. The video emphasizes the importance of memorizing formulas, using a calculator for square roots, and following rounding rules. Viewers are encouraged to practice with a free quiz available after watching.

Why are BSA calculations particularly important for pediatric patients?

• They help in determining the color of medication.

• They determine the flavor of medication suitable for children.

• They are used to calculate the exact time for medication.

• They assist in calculating the most accurate dosage for patients.

What unit is Body Surface Area expressed in?

• Square meters

• Square centimeters

• Liters

• Cubic meters

Which formula is used for BSA calculation when the patient's weight is in kilograms and height in centimeters?

• Weight in grams times height in centimeters divided by 3600

• Weight in kilograms times height in meters squared

• Weight in kilograms times height in centimeters divided by 3600

• Weight in pounds times height in inches divided by 3131

What is the average adult body surface area used in pediatric dosage calculations?

• 1.73 square meters

• 1.5 square meters

• 1.0 square meter

• 2.0 square meters

How do you convert a patient's height from feet and inches to just inches?

• Divide feet by 12 and add inches

• Multiply feet by 10 and add inches

• Multiply feet by 12 and subtract inches

• Multiply feet by 12 and add inches

What is the first step in calculating a pediatric patient's medication dose?

• Converting the patient's weight from pounds to kilograms

• Converting the medication dose from milligrams to grams

• Calculating the patient's body surface area

• Determining the normal adult dose of the medication

For a medication prescribed as 10 mg/m2/day, how is the daily dose calculated?

• Divide the adult dose by the BSA

• Multiply the BSA by 10

• Multiply the BSA by the adult dose

• Divide the BSA by 10

When converting height for BSA calculation, what is the value of one foot in inches?

• 8 inches

• 15 inches

• 12 inches

• 10 inches

In pediatric dosage calculations, what is divided by 1.73 square meters to help determine the child's dose?

• The total amount of medication available

• The child's body surface area

• The child's height

• The child's weight

How do you calculate the amount of medication to administer from a vial labeled 30 mg/mL, given the child's dose?

• Divide the child's dose by 30

• Multiply the child's dose by 30

• Divide 30 by the child's dose

• Multiply 30 by the child's dose
