(Place the unit of measure being calculated on the left side of the equation.) X mL/hr = Step 2: Determine the ratio that contains the same unit as the unit being calculated. (Place the ratio on the right side of the equation, ensuring that the unit in the numerator matches the unit being calculated.) 7 mLX mL/hr = 1 kg Step 3: Place any remaining ratios that are relevant to the item on the right side of the equation, along with any needed conversion factors, to cancel out unwanted units of measurement. 7 mL11 kgX mL/hr = × 1 kg6 hr Step 4: Solve for X. X mL/hr = 12.833333 mL/hr Step 5: Round if necessary. 12.833333 mL/hr = 13 mL/hr Step 6: Determine if the amount to administer makes sense. If the prescription reads 7 mL/kg to infuse over 6 hr, it makes sense to administer 13 mL/hr. The nurse should set the IV pump to deliver D5W IV at 13 mL/hr.
A nurse is preparing to administer morphine 0.05 mg/mL intermittent IV bolus to a newborn who weighs 3 kg. Available is morphine .5 mg/mL injection. How many mL should the nurse administer? (round to the nearest tenth)
Step 1: What is the unit of measurement the nurse should calculate? mg Step 2: Set up an equation and solve for X. X = Dose per kg × Client's weight in kg X mg = 0.05 mg/kg × 3 kg X mg = 0.15 mg Step 3: What is the unit of measurement the nurse should calculate? mL Step 4: What is the dose the nurse should administer? Dose to administer = Desired 0.15 mg Step 5: What is the dose available? Dose available = Have 0.5 mg Step 6: Should the nurse convert the units of measurement? No Step 7: What is the quantity of the dose available? 1 mL Step 8: Set up an equation and solve for X. HaveDesired = QuantityX 0.5 mg0.15 mg = 1 mLX mL X mL = 0.3 mL Step 9: Round if necessary. Step 10: Determine whether the amount to administer makes sense. If there are 0.5 mg/mL and the prescription reads 0.05 mg/kg, it makes sense to administer 0.3 mL. The nurse should administer morphine injection 0.3 mL IV bolus. Follow these steps for the Desired Over Have method of calculation: Step 1: What is the unit of measurement the nurse should calculate? mg Step 2: Set up an equation and solve for X. X = Dose per kg × Client's weight in kg X mg = 0.05 mg/kg × 3 kg X mg = 0.15 mg Step 3: What is the unit of measurement the nurse should calculate? mL Step 4: What is the dose the nurse should administer? Dose to administer = Desired 0.15 mg Step 5: What is the dose available? Dose available = Have 0.5 mg Step 6: Should the nurse convert the units of measurement? No Step 7: What is the quantity of the dose available? 1 mL Step 8: Set up an equation and solve for X. Desired × QuantityX = Have 0.15 mg × 1 mLX mL = 0.5 mg X mL = 0.3 mL Step 9: Round if necessary. Step 10: Determine whether the amount to administer makes sense. If there are 0.5 mg/mL and the prescription reads 0.05 mg/kg, it makes sense to administer 0.3 mL. The nurse should administe
A nurse is caring for a toddler who weighs 13.5 kg. What is the toddler's daily maintenance fluid requirement? (round to nearest whole number)
The formula used to calculate a child's daily maintenance fluid requirement is: 100 mL/kg for the first 10 kg, plus 50 mL/kg for the second 10 kg, plus 20 mL/kg for the remainder of weight in kg. Step 1: What is the child's weight in kg? Determine the child's weight in kg by conversion if necessary. 13.5 kg Step 2: Divide the child's weight into three portions of the weight: the first 10 kg, the second 10 kg, and the remainder of the weight in kg. 10 kg, 3.5 kg Step 3: Multiply the first portion, which is 10 kg, by 100 mL, so 10 × 100 = 1,000 mL. Step 4: Multiply the second portion, which is 3.5 kg, by 50 mL, so that's 3.5 × 50 = 175 mL. Step 5: Add all portions together to determine the child's daily maintenance fluid requirement in mL. 1,000 mL + 175 mL = 1,175 mL. Step 6: Reassess to determine if the amount makes sense. If the child weighs 31.5 kg, it makes sense that the child requires 1,175 mL/day.
