Final answer:
The heparin bolus dose for a 143 lb patient at 70 units/kg, rounded to the nearest 100 units, is 4500 units. To calculate the IV pump infusion rate in milliliters/hour, the concentration of the heparin solution and pump calibration details are required, which are not provided.
Explanation:
To calculate the heparin bolus dose for a patient weighing 143 pounds, we first need to convert the patient's weight to kilograms (1 lb = 0.453592 kg). So, 143 lb is approximately 64.86 kg (143 lb × 0.453592 kg/lb). The bolus dose is then calculated by multiplying the weight in kilograms by 70 units/kg which comes to 4536 units. However, since we're instructed to round to the nearest 100 units, the final bolus dose would be 4500 units.
For the infusion rate, we would calculate this by taking the patient's weight in kilograms and multiplying by the dose 17 units/kg, which equates to 1102.62 units. To set the IV pump, we need to know the concentration of heparin in the IV bag, as well as any specific equipment calibrations. The concentration of the IV bag after adding the 5 mL of 0.550 M heparin solution to 250 mL of fluid becomes diluted to 0.540 M. Without details on the concentration of heparin per milliliter in the IV solution and the calibration of the IV pump (typically given in mL/hour), we cannot provide the exact rate in mL/hour to program the IV pump.
