Final answer:
After converting the patient's weight to kilograms and calculating the bolus at 60 units/kg, the result is 3946.2 units. However, none of the available options from the question match this result. The closest option would be 39 units if we divide by 100, but this needs clarification as it seems incorrect.
Step-by-step explanation:
To calculate the IV bolus for a patient weighing 145 lbs, we must first convert the patient's weight into kilograms using the conversion factor (1 kilogram = 2.20462 pounds). Then we can calculate the bolus as follows:
- Convert 145 lbs to kg: 145 lbs ÷ 2.20462 = 65.77 kg (approximately).
- Calculate the bolus: 65.77 kg × 60 units/kg = 3946.2 units.
After rounding to the nearest whole number, the bolus is 3946 units. However, this number does not match any of the options provided in the question, suggesting there may be an error in the available options or in the question itself. If we misinterpret the options as needing to be divided by 100, then the closest option to our calculated result would be:
- Recommended bolus is approximately 39 units (Option a).
