1. A nurse is caring for a 1-month-old infant who weighs 3500 g and is prescribed a dose of cephazolin 50 mg/kg by intermittent IV bolus three times daily. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) 175 mg Correct Rationale: Convert gm to kg: STEP 1: What is the unity of measurement to calculate? Kg STEP 2: Set up the equation and solve for X. 1000 gm/1 kg = client's weight in gm/X kg 1000 gm/1 kg = 3500 g/X kg X = 3.54 kg STEP 3: Round, if necessary. STEP 4: Reassess to determine whether the conversion to kg makes sense. If 1000 gm = 1 kg, it makes sense that 3500 gm = 3.5 kg. Calculate Dose: STEP 1: What is the unit of measurement to calculate? mg STEP 2: Set up the equation and solve for X. mg x kg/dose = X 50 mg x 3.5 kg = 175 mg STEP 3: Round, if necessary. STEP 4: Reassess to determine whether the amount to administer makes sense. If the provider prescribed 50 mg/kg/dose and the client weighs 3.5 kg, it makes sense to administer 175 mg per dose. The nurse should administer cephazolin 175 mg by intermittent IV bolus 3 times daily. InCorrect Rationale: Convert gm to kg: STEP 1: What is the unity of measurement to calculate? Kg STEP 2: Set up the equation and solve for X. 1000 gm/1 kg = client's weight in gm/X kg 1000 gm/1 kg = 3500 g/X kg X = 3.54 kg STEP 3: Round, if necessary.
