5% dextrose
9% normal saline
lactated ringers solution
5% dextrose with 0.9% sodium chloride
question 7 (2.5 points)

1.5 g
2.0 g
2.5 g
question 8 (2.5 points)
a multidose vial of oxacillin 2 g is reconstituted with 8 ml of bacteriostatic water to
yield 250 mg/ml. how many ml of the medication should be given if the patient is
prescribed 500 mg of the medication?
1 ml

Explanation:

Question 6

D5NS is a medical abbreviation where D5 means 5% dextrose and NS means normal saline (0.9% sodium chloride). So the solution is 5% dextrose with 0.9% sodium chloride.

Step1: Understand the concentration

The reconstituted solution has a concentration of 2 g/mL, meaning each milliliter contains 2 grams of the medication.

Step2: Determine the amount in 1 mL

Since the concentration is 2 g/mL, 1 mL of the medication will contain 2.0 g of piperacillin.

Step1: Identify the concentration

The concentration of the Oxacillin solution is 250 mg/mL, which means each milliliter contains 250 milligrams of Oxacillin.

Step2: Calculate the volume for 500 mg

We use the formula \( \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} \). Substituting the values, we get \( \text{Volume} = \frac{500\ \text{mg}}{250\ \text{mg/mL}} = 2\ \text{mL} \) (assuming the option with 2 mL is present, as the visible option shows 1 mL but likely a typo or missing, but based on calculation it's 2 mL).

Answer:

D. 5% dextrose with 0.9% sodium chloride
