Detailed Answer KeyATI Math Remediation #1
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.

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.
2. A nurse is caring for an adolescent client who has pneumonia and a prescription for cefpodoxime 5 mg/kg PO every
12 hr for 5 days. The client weighs 88 lb. How many mg 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.)
200 mg
Correct Rationale: Convert lb to kg:STEP 1: What is the unit of measurement to calculate? kg
STEP 2: Set up the equation and solve for X.
2.2 lb/1 kg = client's weight in lb/X kg
2.2 lb/1 kg = 88 lb/X kg
X = 40
STEP 3: Round, if necessary.
STEP 4: Reassess to determine whether the conversion to kg makes sense. If 2.2 lb = 1
kg, it makes sense that 88 lb = 40 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
5 mg x 40 kg = 200 mg
STEP 3: Round, if necessary.
STEP 4: Reassess to determine whether the amount to administer makes sense. If the
provider prescribed cefpodoxime 5 mg/kg/dose and the client weighs 40 kg, it makes
sense to administer 200 mg per dose. The nurse should administer cefpodoxime 200 mg
PO every 12 hr.
InCorrect Rationale: Convert lb to kg:STEP 1: What is the unit of measurement to calculate? kg
STEP 2: Set up the equation and solve for X.
2.2 lb/1 kg = client's weight in lb/X kg
2.2 lb/1 kg = 88 lb/X kg
X = 40
