C.

65 mL

D.

88 mL

Answer and Explanation

The Correct Answer is B

Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)

Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)

Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL

So, the nurse should administer 64 mL to the patient.

Correct Answer is A

Explanation

To determine the mL per dose of heparin, we can use the following formula:

mL per dose = (total units needed) / (concentration of heparin in units/mL). Substituting the values given in the

Question :.

mL per dose = 10,000 units / 20,000 units/mL = 0.5 mL per dose.

Therefore, the client should receive 0.5 mL per dose of heparin from the vial containing a concentration of 20,000 units/mL.

Correct Answer is D

Explanation

To calculate the amount of magnesium sulfate to be added to the normal saline, we can use the formula:

Concentration = Dose / Volume Plugging in the given values, we get:

Concentration = 2 g / 50 mL Simplifying, we get:

Concentration = 0.04 g/mL

To find the amount of magnesium sulfate needed for 1000 mL of normal saline, we can multiply the concentration by the volume:

Amount = Concentration × Volume Amount = 0.04 g/mL × 1000 mL Amount = 40 g

Therefore, 40 g of magnesium sulfate must be added to 1000 mL of normal saline to provide the ordered infusion.
