A client is prescribed 250 mg of metformin. The pharmacy supplies 500 mg pre- scored tablets of metformin. How should the nurse administer the medication to the client?

Administer one half tablet

Administer two tablets

Administer one tablet

Administer one-and-a-half tablets

Answer and Explanation

The Correct Answer is A

Administer one half tablet. To find the amount of tablets to administer, use the formula: (ordered dose / available dose). In this case, (250 mg / 500 mg) = 0.5 tablet. Since the tablet is pre-scored, it can be easily split in half.

Metformin is a medication that belongs to a class of drugs called biguanides. It is used to treat type 2 diabetes by lowering blood sugar levels and improving insulin sensitivity. Metformin works by reducing the amount of glucose produced by the liver and increasing the uptake of glucose by the muscles and other tissues.

Metformin can also help prevent or delay the onset of diabetes complications, such as heart disease and kidney damage.

Correct Answer is B

Explanation

To calculate the answer, we can use the following formula:.

(mg of drug required / total mg in vial) x total volume in vial = mL to administer. First, let's convert the dose from mg to g:.

80 mg = 0.08 g.

Next, let's plug in the values:. (0.08 g / 1 g) x 8 mL = 0.64 mL.

Therefore, the nurse should administer 0.64 mL of Solu-Medrol.

A. 9 hr and 15 min B. 9 hr and 24 min C. 9 hr and 30 min D. 9 hr and 40 min

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).
