question 12
a patient is prescribed to receive 1 l of d5w to infuse at 100 ml/hr. how long will it take to infuse this solution?
8 hours
10 hours
15 hours
20 hours
2.5 / 2.5 points
question 13
what solution strength is created if 8 fl oz of hydrogen peroxide is mixed with 8 fl oz of saline?
½ strength

Explanation:

Question 12

Step1: Convert liters to milliliters

We know that \( 1 \text{ L} = 1000 \text{ mL} \).

Step2: Use the formula for time (Time = Volume / Rate)

The volume is \( 1000 \text{ mL} \) and the rate is \( 100 \text{ mL/hr} \). So, \( \text{Time} = \frac{1000 \text{ mL}}{100 \text{ mL/hr}} = 10 \text{ hours} \). Wait, but the selected option was 20 hours, that seems incorrect. Wait, maybe I made a mistake? Wait no, 1L is 1000mL, 1000 divided by 100 is 10. But the original selected option was 20, maybe a typo? But according to the calculation, the correct answer should be 10 hours.

When mixing 8 fl oz of hydrogen peroxide with 8 fl oz of saline, the total volume is \( 8 + 8 = 16 \) fl oz. The amount of hydrogen peroxide is 8 fl oz. The strength is calculated as \( \frac{\text{Volume of solute}}{\text{Total volume of solution}}=\frac{8}{16}=\frac{1}{2} \). So the solution strength is ½ strength.

Answer:

B. 10 hours

Question 13 (assuming the first option is ½ strength)
