A 110-pound, adult female is admitted to the Emergency Center after receiving burns to 40 percent of her body. Using the Parkland formula, the client's fluid requirements for the first 24 hours after injury is calculated using Lactated Ringer's 4 ml solution x Body weight (in kilograms) x Percent burn. The client should receive one-half of the 24-hour calculated fluid volume in the first 8 hours of treatment. The nurse should set the infusion pump to deliver how many ml/hour during the first 8 hours? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["499"]
Calculating the Lactated Ringer's Infusion Rate
Step 1: Convert pounds to kilograms:
110 pounds x (1 kg / 2.20462 pounds) ≈ 49.9 kg
Step 2: Calculate the total fluid requirement for 24 hours using the Parkland formula:
Total Fluid (mL) = 4 mL/kg/%TBSA x Body Weight (kg) x %TBSA
Total Fluid = 4 mL/kg/%TBSA x 49.9 kg x 40%
Total Fluid = 7984 mL
Step 3: Calculate the fluid volume for the first 8 hours:
First 8 Hours Fluid = Total Fluid / 2
First 8 Hours Fluid = 7984 mL / 2
First 8 Hours Fluid = 3992 mL
Step 4: Calculate the infusion rate for the first 8 hours:
Infusion Rate (mL/hour) = First 8 Hours Fluid / 8 hours
Infusion Rate = 3992 mL / 8 hours
Infusion Rate ≈ 499 mL/hour
Therefore, the nurse should set the infusion pump to deliver approximately 499 mL/hour during the first 8 hours.

Explanation
Calculating the Inamrinone Infusion Rate
Step 1: Convert weight to kilograms:
183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg
Step 2: Calculate the desired dose rate in mcg/minute:
8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute
Step 3: Calculate the concentration of inamrinone in the IV solution:
0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL
Step 4: Calculate the infusion rate in mL/hour:
First, convert mcg to mg:
664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute
Then, set up a proportion:
x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL
Cross-multiply and solve for x:
x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL
x mL/hour ≈ 40 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
Correct Answer is ["2"]
Explanation
Understanding the Problem:
We need to administer 500 mg of amoxicillin/clavulanate potassium.
The available tablets contain 250 mg amoxicillin and 125 mg clavulanate potassium.
Solution:
Determine the total amount of active ingredients in the available tablets:
250 mg (amoxicillin) + 125 mg (clavulanate potassium) = 375 mg/tablet
Calculate the number of tablets needed:
500 mg (desired dose) / 375 mg/tablet = 1.33 tablets
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets for each dose.
