A client is prescribed 10,000 units of heparin. How many mL per dose should be administered from a vial containing heparin, with a concentration of 20,000 units/mL?

A.

0.5 mL

B.

1 mL

C.

1.5 mL

D.

2 mL

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get: Time = 1.5 L / 75 mL/hr

Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

Therefore, it will take 20 hours to finish the infusion at the current rate.
