A client with dehydration receives a prescription for an IV of Lactated Ringer's 1,000 ml to be administered over 8 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only, using whole number.)
The Correct Answer is ["125"]
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
Plugging in the given values:
Infusion Rate = 1000 mL / 8 hours
Calculating the result:
Infusion Rate = 125 mL/hour
Therefore, the nurse should program the infusion pump to deliver 125 mL/hour.

Calculating the Alprazolam Dose
Problem: Administer 0.75 mg of alprazolam PO. The available concentration is 0.5 mg/tablet.
Steps:
Set up a proportion:
We want to find the number of tablets needed.
We know the desired dose (0.75 mg) and the concentration of the medication (0.5 mg/tablet).
Proportion:
x tablets / 0.75 mg = 1 tablet / 0.5 mg
Cross-multiply:
0.5x = 0.75
Solve for x:
x = 0.75 / 0.5
x = 1.5
Answer: The nurse should administer 1.5 tablets of alprazolam per dose.
Correct Answer is ["3.2"]
Explanation
To calculate the volume of tobramycin sulfate to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
First, let's convert the desired dose from grams to milligrams:
0.128 grams x 1000 mg/gram = 128 mg
Then, plug in the values into the formula:
Volume (mL) = 128 mg / 40 mg/mL
Calculating the result:
Volume (mL) = 3.2 mL
Therefore, the nurse should administer 3.2 mL of tobramycin sulfate.
