A nurse is preparing to administer albuterol syrup 6 mg PO tid. Available is albuterol 2 mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
To determine the correct dosage of albuterol syrup, the nurse needs to perform a simple calculation. The prescription requires 1.6 mg of albuterol per dose. With the available concentration of 2 mg per 5 mL, the nurse can calculate the volume of syrup needed by setting up a proportion: (2 mg / 5 mL = 1.6 mg / X mL). Solving for X gives us (1.6 mg * 5 mL) / 2 mg, which equals 4 mL.
