A physician ordered 5 mL 10% dextrose stat. The only dextrose available is a vial of 5 mL 50% dextrose.
How can the nurse provide the appropriate dose?

Dextrose 50%, add 1 mL to 4 mL injectable saline

Dextrose 50%, add 2 mL to 3 mL injectable saline

Dextrose 50%, add 3 mL to 2 mL injectable saline

Dextrose 50%, add 4 mL to 1 mL injectable saline

Answer and Explanation

The Correct Answer is A

Dextrose 50%, add 1 mL to 4 mL injectable saline. To obtain 5 mL of 10% dextrose, 0.5 mL of the 50% dextrose should be diluted with 4.5 mL of sterile water or normal saline. Therefore, the nurse should add 1 mL of the 50% dextrose to 4 mL of injectable saline to get a final concentration of 10% dextrose in 5 mL. This will give the client the appropriate dose.

Choice B is incorrect because adding 2 mL of the 50% dextrose to 3 mL of saline would give a final concentration of 20%, which is higher than the prescribed concentration of 10%.

Choice C is incorrect because adding 3 mL of the 50% dextrose to 2 mL of saline would give a final concentration of 30%, which is significantly higher than the prescribed concentration of 10%.

Choice D is incorrect because adding 4 mL of the 50% dextrose to 1 mL of saline would give a final concentration of 40%, which is much higher than the prescribed concentration of 10%.

Correct Answer is B

Explanation

We can use the following formula to calculate the infusion time:

Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)

First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:

19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:

Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours

To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:

9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)

Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).

A. 0.5 mL B. 1 mL C. 1.5 mL D. 2 mL

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.
