Study Notes
Safe Dosage Calculations
- Ensure safe dosage calculations by checking results for reasonableness.
Metric Prefixes
- Kilo = x1,000; milli = /1,000; micro = /1,000,000 (correct option: D).
Keflex Dosage Calculation
- For a 500 mg order of Keflex with the available 250 mg/5 mL, administer 10 mL.
Decadron Dosage Calculation
- A dosage of 6 mg IM using 4 mg/mL Decadron requires 1.5 mL.
Glyburide Tablet Calculation
- To achieve a 5 mg dose from 1.25 mg tablets, the patient must take 4 tablets.
PO BID Interpretation
- The abbreviation "PO BID" indicates the medication should be taken by mouth twice a day.
Ceclor Dose in mg
- The order for Ceclor at 0.375 g translates to 375 mg for administration.
