BSA calculation. Please help!

15. What would the dose be for a child whose BSA is 0.51 m'? (Based off same recommendation from #11) 16. If a dose of 3.5 mg is ordered for this patient by the physician, would the dose be safe? 17. A patient with Hodgkins disease who weighs 60 kg and is 142 cm tall is to receive Blenoxane IV. What is her BSA? 18. Based off of the recommendation of "10 to 20 mg/ m? given intravenously for each dose", what would is the recommended safe dosage range for this patient? Minimum: mg to Maximum: mg 19. If a dosage of 20 mg is ordered, would it be safe?BODY SURFACE AREA METHOD The BSA is an important measure in calculating dosages for infants and children. BSA is also user selected adult populations, such as those undergoing open-heart surgery or radiation therapy, se burn victims, and those with renal disease. Regardless of age, antineoplastic agents (chemother drugs) and an increasing number of other highly potent drug classifications are being prescribed be on BSA. BSA is a mathematical estimate using the patient's height and weight. BSA is expressed in squ meters (m?). BSA can be determined by formula calculation or by using a chart, referred to as a no gram, that estimates the BSA. Because drug dosages recommended by BSA measurement are pot and because the formula calculation is the most accurate, we will begin with the formulas. In most uations, the prescribing practitioner will compute the BSA for drugs ordered by this method. Howe the nurse who administers the drug is responsible for verifying safe dosage, which may require ca lating the BSA. . BSA Formula One BSA formula is based on metric measurement of height in centimeters and weight in kilograms. other is based on household measurement of height in inches and weight in pounds. Either is easy to co pute using the square root function on a calculator. BSA calculators are also readily available on the Inter RULE R To calculate BSA in m based on metric measurement of height and weight: " BSA (m?) = ht (cm) x wt (kg) 3,600 To calculate BSA in m based on household measurement of height and weight: " BSA (m?) = ht (in) x wt (ib) 3,131Calculating BSA 1. 58 lb, 36 in: m? 2. 74 kg, 160 cm: m2 3. 14.2 kg, 64 cm: m' 4. 69 kg, 170 cm: m 2 5. 103 lb, 55 in: 6. 25.3 kg, 112 cm: m? 7. 55 kg, 157.5 cm: 8. 65.4 kg, 132 cm: m? 9. 26.5 lb, 58 in: m2 10. 13.6 kg, 60 cm: 11.
