A client has received a prescription for a fluid bolus of 0.9% sodium chloride, 200 mL to be infused in 30 minutes. How many mL/hr should the nurse program the infusion pump to deliver? (Please enter the numerical value only.)
The question is asking for the rate at which the infusion pump should be programmed to deliver a fluid bolus of 200 mL in 30 minutes. This can be calculated using the formula for rate which is volume divided by time.
The Correct Answer is ["400"]
Step 1: Convert the volume of fluid to be infused from mL to L (since the rate is usually measured in mL/hr):
200 mL = 200 mL (No conversion needed as the volume is already in mL)
Step 2: Convert the time for infusion from minutes to hours (since the rate is usually measured in mL/hr):
30 minutes = 30 ÷ 60 = 0.5 hours
Step 3: Calculate the rate (volume ÷ time):
Rate = Volume ÷ Time
Rate = 200 mL ÷ 0.5 hours
Rate = 400 mL/hr
The nurse should program the infusion pump to deliver at a rate of 400 mL/hr.

Correct Answer is C
Explanation
Choice A reason: Decreased bowel sounds may be associated with cirrhosis due to altered digestion but do not directly correlate with weight gain.
Choice B reason: An increased respiratory rate can be a sign of many conditions, including fluid overload, but it is not a specific indicator of weight gain due to fluid accumulation.
Choice C reason: Increased abdominal girth is a common sign of ascites, which is fluid accumulation in the abdomen often seen in cirrhosis, correlating with the reported weight gain.
Choice D reason: Decreased level of consciousness may indicate hepatic encephalopathy in cirrhosis patients but does not directly correlate with the weight gain described.

Correct Answer is ["2.4"]
Explanation
Step 1: Convert the weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, the weight in kg is:
175 lbs ÷ 2.2 = 79.55 kg
Step 2: Calculate the total units of heparin needed. The prescription is for 3 units/kg, so:
3 units/kg × 79.55 kg = 238.65 units
Step 3: Calculate the volume of heparin to administer. The vial is labeled as "100 units/mL", so:
238.65 units ÷ 100 units/mL = 2.39 mL
So, the nurse should administer approximately 2.4 mL of heparin (rounded to the nearest tenth).
