A client with chronic constipation reports taking 2 ounces of magnesium hydroxide at bedtime. The bottle is labeled "Magnesium hydroxide saline laxative, USP 400 mg per 5 mL. How many mL should the nurse document in the medical record? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["59.147"]

Here's how to calculate the number of mL the nurse should document:

Client dosage: 2 ounces (given)

Conversion factor: 1 ounce (oz) = 29.5735 mL (conversion factor)

Magnesium hydroxide concentration: 400 mg per 5 mL (from bottle label)

We need to find the equivalent volume in mL of the 2 ounces dosage the client reported.

Steps:

a. Convert ounces to mL:

Client dosage (mL) = Client dosage (oz) x Conversion factor (mL/oz)

Client dosage (mL) = 2 oz * 29.5735 mL/oz

Client dosage (mL) = 59.147 mL (round to nearest hundredth)

Correct Answer is ["1.5"]

Explanation

First, we need to convert the prescribed dose from mg to mcg because the available medication is labeled in mcg.

1 mg is equal to 1,000 mcg. So, 0.075 mg is equal to 75 mcg.

Given:

The prescription is for 75 mcg of levothyroxine.

The available medication is 50 mcg/tablet.

We can set up the proportion as follows:

75mcg/ xtablet = 50mcg/1tablet

Solving for x gives us the number of tablets that the nurse should administer.

Cross-multiplying and solving for x:

X = 75mcg×1tablet/50mcg

After performing the calculation, we find that x equals 1.5 tablets.

So, the nurse should administer 1.5 tablets of the medication. This is rounded to the nearest tenth as per the instructions.

Correct Answer is ["111"]

Explanation

Here's how to calculate the rate for the infusion pump:

Total volume to infuse: 1 liter (given)

Infusion time: 9 hours (given)

We need to find the volume delivered per hour (mL/hour) considering the total volume and infusion time.

Volume conversion: Since the volume is given in liters, convert it to mL:

1 liter * 1000 mL/liter = 1000 mL

Infusion rate (mL/hour):

Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 1000 mL / 9 hours

Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest tenth)

Therefore, the nurse should program the infusion pump to deliver approximately 111 mL/hour.
