Question

what solution strength is created if 8 fl oz of hydrogen peroxide is mixed with 8 fl oz of saline?
¼ strength
1/3 strength
½ strength
2/3 strength
question 14 (2.5 points)
a vial of ancef 1 g is reconstituted with 5 ml of normal saline to yield 125 mg/ml. how many ml of the medication should be given if a patient is prescribed 250 mg of the medication?
1.0 ml
1.25 ml
1.5 ml
2.0 ml

Explanation:

First Question (Solution Strength)

Step1: Find total volume

Total volume = hydrogen peroxide volume + saline volume = \( 8 + 8 = 16 \) fl oz.

Step2: Calculate solution strength

Solution strength = (volume of hydrogen peroxide) / (total volume) = \( \frac{8}{16} = \frac{1}{2} \).

Step1: Recall the formula

Volume = (Desired dose) / (Concentration)

Step2: Substitute values

Desired dose = 250 mg, Concentration = 125 mg/mL. So Volume = \( \frac{250}{125} = 2.0 \) mL.

Answer:

½ strength
