Calculation
A nurse is preparing to administer sumatriptan 6 mg subcutaneous to a client. Available is sumatriptan injection 6 mg/0.5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculation: Desired dose = 6 mg. Available concentration is 6 mg/ 0.5 mL. Step 3: Calculate the volume to administer. Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL)) = 6 mg /(6 mg/ 0.5 mL) = 6 mg/ 12 mg/ mL = 0.5 mL.
