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.
Ceclor Volume Calculation
- To administer a dose of Ceclor 0.375 g PO BID from a suspension of 187 mg/5 mL, give 10 mL.
Ceftriaxone Injection Calculation
- Administer 135 mg of ceftriaxone from a vial of 1 g/15 mL by injecting 2 mL.
"q6h" Meaning
- The term "q6h" signifies that the medication should be given every 6 hours.
Zinacef Dosage for Child
- A 5-year-old child weighing 44 lbs should receive 250 mg of Zinacef per dose with an order of 50 mg/kg/day IM.
Weight Conversion
- To convert 44 lbs to kg, divide by 2.2, resulting in approximately 20 kg.
Gemcitabine Dosage Calculation
- For an order of gemcitabine at 400 mg/m² IV based on a BSA of 0.47 m², calculate the required dose using available vials.
