Question

interactive medical math worksheet
section 1: uses of medical math

• dosage calculations: correct medication amounts
• iv flow rates: drops per minute or ml per hour
• conversions: mg ↔ g, ml ↔ l, lbs ↔ kg
• vital signs: ratios, percentages, and conversions
• time management: scheduling medications using military time

why is medical math important? prevents medication errors, ensures patient safety, and maintains accuracy in treatment plans.
section 2: key formulas

• basic dosage: dose required = (desired dose / available dose) × quantity available
• iv flow rate: flow rate (gtt/min) = (volume (ml) × drop factor (gtt/ml)) / time (min)
• weight conversion: kg = lb / 2.2
• temperature conversion: °c = (°f - 32) × 5/9; °f = (°c × 9/5) + 32

section 3: military time practice
convert the following:

• 2:15 pm → __
• 11:45 am → __
• 7:30 pm → __

convert these military times:

• 1430 → __
• 0915 → __
• 2230 → __

Explanation:

Step1: Convert 2:15 PM to military time

For PM times (excluding 12 PM), add 12 to the hour. So 2 + 12 = 14, so 2:15 PM is 1415.

Step2: Convert 11:45 AM to military time

AM times (excluding 12 AM) remain the same, so 11:45 AM is 1145.

Step3: Convert 7:30 PM to military time

Add 12 to 7: 7 + 12 = 19, so 7:30 PM is 1930.

Step4: Convert 1430 to standard time

Subtract 12 from 14: 14 - 12 = 2, so 1430 is 2:30 PM.

Step5: Convert 0915 to standard time

AM time, so it's 9:15 AM.

Step6: Convert 2230 to standard time

Subtract 12 from 22: 22 - 12 = 10, so 2230 is 10:30 PM.

Answer:

• 2:15 PM → 1415
• 11:45 AM → 1145
• 7:30 PM → 1930
• 1430 → 2:30 PM
• 0915 → 9:15 AM
• 2230 → 10:30 PM
