Question

a vial of ceftazidime 2 g is reconstituted with 2 ml of normal saline to yield 1 g/ml. how many ml of the medication should be given if a patient is prescribed 1.5 grams of the medication?
0.50 ml
0.75 ml
1.5 ml
1.25 ml
question 20 (2.5 points)
a vial of monocid 1 g is reconstituted with 2.5 ml of sterile water to yield 325 mg/ml. how many ml of the medication should be given if a patient is prescribed to receive 500 mg of the medication?
1.0 ml
1.5 ml
2.0 ml

Explanation:

First Question (Ceftazidime)

Step1: Recall the concentration formula

Concentration \( C = \frac{\text{Mass }(m)}{\text{Volume }(V)} \), so \( V=\frac{m}{C} \).

Step2: Identify given values

Mass \( m = 1.5 \, \text{g} \), Concentration \( C = 1 \, \text{g/mL} \).

Step3: Calculate volume

Substitute into the formula: \( V=\frac{1.5 \, \text{g}}{1 \, \text{g/mL}} = 1.5 \, \text{mL} \).

Step1: Recall the concentration formula

Concentration \( C = \frac{\text{Mass }(m)}{\text{Volume }(V)} \), so \( V=\frac{m}{C} \).

Step2: Identify given values

Mass \( m = 500 \, \text{mg} \), Concentration \( C = 325 \, \text{mg/mL} \).

Step3: Calculate volume

Substitute into the formula: \( V=\frac{500 \, \text{mg}}{325 \, \text{mg/mL}} \approx 1.54 \, \text{mL} \), closest to 1.5 mL (among options 1.0 mL, 1.5 mL, 2.0 mL).

Answer:

1.5 mL (Option: 1.5 mL)
