Question

multiple choice 2 points a patient/client weighs 110 lb. available is heparin 25,000 units in 1000 ml of d5w. the healthcare provider orders a heparin sodium iv bolus of 80 units/kg and a starting dose at 18 units/kg/hour. how much would the nurse give as the bolus dose? 1000 units/hour 4000 units/hour 900 units/hour 3900 units/hour previous next

Explanation:

Step1: Convert pounds to kilograms

First, we know that 1 lb = 0.453592 kg. So for a patient weighing 110 lb, the weight in kg is $110 \times 0.453592 \approx 49.8951$ kg.

Step2: Calculate the bolus dose in units

The healthcare provider orders a heparin sodium IV bolus of 80 units/kg. So the bolus dose is $80 \times 49.8951 \approx 3991.61$ units, which is approximately 3900 units (or closer to 3992, but among the options, 3900 units/hour is the closest if we consider possible rounding or the options given). Wait, maybe I misread the order. Wait, the problem says "a heparin sodium IV bolus of 80 units/kg and a starting dose at 18 units/kg/hour". Wait, the question is about the bolus dose. Wait, let's recalculate. 110 lb to kg: $110 \div 2.2 = 50$ kg (since 1 kg = 2.2 lb, a common approximation). Then 80 units/kg 50 kg = 4000 units? Wait, 110 divided by 2.2 is 50. So 80 50 = 4000 units. Wait, maybe the 2.2 lb/kg conversion is used here. Let's check: 110 lb / 2.2 lb/kg = 50 kg. Then 80 units/kg * 50 kg = 4000 units. So the bolus dose is 4000 units. Wait, but the options include 4000 units/hour? Wait, maybe the question is about the starting dose? Wait, no, the question says "how much would the nurse give as the bolus dose?". Wait, let's re-express:

Patient weight: 110 lb. Convert to kg: 110 / 2.2 = 50 kg (using the common medical conversion of 2.2 lb per kg).

Bolus dose: 80 units/kg. So 80 * 50 = 4000 units. So the bolus dose is 4000 units. But the options have 4000 units/hour? Wait, maybe there's a misprint, but among the options, 4000 units/hour (or maybe the bolus is given as a dose, but the options are in units/hour? Wait, no, the starting dose is 18 units/kg/hour. Wait, maybe I misread the question. Let me check again: "A patient/client weighs 110 lb. Available is heparin 25,000 units in 1000 mL of D5W. The healthcare provider orders a heparin sodium IV bolus of 80 units/kg and a starting dose at 18 units/kg/hour. How much would the nurse give as the bolus dose?"

So bolus dose: 80 units/kg. Weight: 110 lb = 50 kg (110 / 2.2). So 80 * 50 = 4000 units. So the bolus dose is 4000 units. So the answer should be 4000 units (the option is 4000 units/hour? Maybe a typo, but that's the closest).

Answer:

4000 units/hour (assuming the option's unit is a typo and it's the bolus dose, or the question is about the starting dose? Wait, no, the bolus is 80 units/kg. So 80*50=4000. So the answer is 4000 units (the option with 4000 units/hour is the correct one here).
