tailieunhanh - Lecture Math for the pharmacy technician: Concepts and calculations: Chapter 10 – Lynn M. Egler, Kathryn A. Booth

Chapter 10, Pediatric and geriatric considerations. This chapter includes drug orders based upon body weight. It introduces body surface area (BSA) calculations. Discussions of special concerns for pediatric and geriatric patients are also presented. | Math for the Pharmacy Technician: Concepts and Calculations Chapter 10: Pediatric and Geriatric Considerations Egler • Booth Pediatric and Geriatric Considerations Need higher resolution chapter opener file from chapter. Learning Objectives Explain why dosages calculations for specific populations must be based on the individual patient. Identify factors that affect the absorption, distribution, biotransformation, and elimination of drugs in special populations. Determine safe doses for special population patients. When you have successfully completed Chapter 10, you will have mastered skills to be able to: 10- Learning Objectives (con’t) Determine safe doses for special populations. Calculate patient dosages based on body weight. Calculate pediatric dosages using Clark’s Rule. Calculate pediatric dosages using Young’s Rule. 10- Learning Objectives (con’t) Find a patient’s body surface area (BSA). Calculate patient dosages based on a patient’s BSA. 10- Introduction Two . | Math for the Pharmacy Technician: Concepts and Calculations Chapter 10: Pediatric and Geriatric Considerations Egler • Booth Pediatric and Geriatric Considerations Need higher resolution chapter opener file from chapter.
