NREMT Paramedic Cognitive ExamOperationsMedium
A paramedic is preparing to administer 2 mg of Naloxone IV push. The medication is supplied in a vial containing 0.4 mg/mL. How many milliliters should the paramedic administer?
- A0.8 mL
- B2 mL
- C4 mL
- D5 mL
Show answer & explanationAnswer & explanation
Correct answer: D. 5 mL
To calculate the volume, use the formula: Dose Ordered / Concentration Available = Volume to Administer. 2 mg / 0.4 mg/mL = 5 mL.
Why the other options are wrong
- A. Incorrect calculation (e.g., 2 mg * 0.4 mg/mL).
- B. Incorrect calculation (e.g., 0.4 mg/mL * 5 = 2 mg, but the question asks for mL, not mg).
- C. Incorrect calculation (e.g., 2 mg / 0.5 mg/mL if misread).
Medication Dosage Calculation
The process of determining the correct volume or amount of medication to administer based on the desired dose and the available concentration of the drug.
- Formula: Dose Ordered / Concentration Available = Volume to Administer.
- Ensure units are consistent (e.g., mg to mg, mL to mL).
- Crucial for patient safety and accurate drug delivery.
Memory trick: Desired on top, have on the bottom, times the volume, don't be forgotten!
