question 12 (3 points)
you receive an order for lactated ringers (lr) 1000 ml to run at 125 ml/h. how long will this iv last?

Explanation:

Question 11

Step1: Convert liters to milliliters

We know that \( 1 \text{ L} = 1000 \text{ mL} \). So the volume of the IV bag is \( 1000 \text{ mL} \).

Step2: Calculate time using formula \( \text{Time} = \frac{\text{Volume}}{\text{Rate}} \)

The rate is \( 150 \text{ mL/hr} \), and the volume is \( 1000 \text{ mL} \). So \( \text{Time} = \frac{1000}{150} \approx 6.66 \text{ hours} \).

Step1: Identify volume and rate

The volume of the IV is \( 1000 \text{ mL} \) and the rate is \( 125 \text{ mL/h} \).

Step2: Use the formula \( \text{Time} = \frac{\text{Volume}}{\text{Rate}} \)

Substitute the values: \( \text{Time} = \frac{1000}{125} = 8 \text{ hours} \).

Answer:

C. 6.66 hours
