A client on the palliative care unit is receiving midazolam 3 mg SUBQ every 2 hours PRN for terminal agitation and intractable hiccups. The medication iS available in a 5 mL ampoule labeled. "2 mg/mL." How many mL should the nurse administer for each dose? (Enter the numerical value only.)
Correct Answer: 1.5
Given:
Ordered dose of Midazolam: 3 mg SUBQ every 2 hours PRN
Concentration of Midazolam: 2 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
3 mg / Volume = 2 mg/mL
Step 3: Solve for the unknown volume:
Volume = 3 mg / (2 mg/mL)
Volume = 3 mg x (1 mL / 2 mg)
Volume = 1.5 mL
