1-A nurse is preparing to administer cefaclor 40 mg/kg/day PO divided in equal doses every 8
hr to a child who weighs 48 lb. Available is cefaclor
... [Show More] suspension 375 mg/5 mL. How many mL
should the nurse administer per dose?
3.9 mL
Step 1: What is the unit of measurement the nurse should calculate? kg
Step 2: Set up an equation and solve for X.
X kg = 21.818181 kg
Step 3: What is the unit of measurement the nurse should calculate? mg
Step 4: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 40 mg/kg × 21.818181 kg
X mg = 872.727272 mg
The dose is divided equally every 8 hours; therefore, divide X by 3.
Step 5: What is the unit of measurement the nurse should calculate? mL
Step 6: What is the dose the nurse should administer? Dose to administer = Desired 290.909090 mg
Step 7: What is the dose available? Dose available = Have 375 mg
Step 8: Should the nurse convert the units of measurement? No
Step 9: What is the quantity of the dose available? 5 mL
Step 10: Set up an equation and solve for X.
X mL = 3.878787 mL

X kg = 22.727272 kg
Step 3: What is the unit of measurement the nurse should calculate? mEq
Step 4: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mEq = 2 mEq/kg × 22.727272 kg
X mEq = 45.454545 mEq
The dose is divided equally every 12 hours; therefore, divide X by 2.
3-A nurse is preparing to administer gentamicin to a client who weighs 165 lb. The
medication reference recommends administering 2 mg/kg IM every 8 hr. How many mg
should the nurse plan to administer per dose?
150 mg
Step 1: What is the unit of measurement the nurse should calculate? kg
Step 2: Set up an equation and solve for X.
X kg = 75 kg
Step 3: What is the unit of measurement the nurse should calculate? mg
Step 4: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 2 mg/kg × 75 kg
X mg = 150 mg [Show Less]
