Study Notes
Medication Dosage Calculations
- Diflucan Order: 350 mg by mouth (PO) daily.
- Common Unit Conversion: Understanding milliliters in relation to medication dosages is crucial for accurate administration.
Dose Calculation Practice
- Heparin Example: Order for 2,000 units; available in 1,000 units/mL. Calculate mL for dosage.
- Labetalol Dosage: 40 mg IV twice daily; vial contains 100 mg/20 mL, total daily mg calculation is required.
IV and PO Medications
- Digoxin Administration: 1,000 mcg IV daily, divided into four doses from a vial labeled 500 mcg/2 mL.
- Protonix Dosage: 20 mg IV daily from a vial labeled 40 mg/2mL, needing to determine mL per dose.
Pediatric and Weight-Based Calculations
- Weight-Based Dosing: For medications like Penicillin, understanding kg to lb conversion (1 lb = 0.453592 kg) is necessary for accurate mg determination.
- Infant Safe Dosage: Consider recommended dosage ranges per kg for different medications, ensuring it falls within the safe limits.
Liquid Measurement Conversion
- Common Liquid Conversion: Understanding that 1 teaspoon (tsp) is approximately 5 mL aids in practical calculations for oral liquid medications.
- Milliliters to Milligrams: Acknowledge concentration labels (e.g., 10 mg/1 mL) when calculating dosages in mL.
General Calculation Strategies
- Using Available Labels: Familiarize with vial concentrations to accurately determine dosage in mL for both IV and PO medications.
- Daily Total Administration: For multiple daily doses, multiply the per-dose amount by the number of doses to get the total daily requirement.
Doctor's Orders
- Accuracy in Transcription: Always check and double-check the written orders to ensure precision in dose calculation and patient safety.
Summary of Key Calculations
- Mastering the conversion between mg/mL and the implications of drug concentration is vital for safe nursing practices.
- Regular practice with example problems improves proficiency, preparing for real-world medication administration scenarios.
