The healthcare provider prescribes 0.075 mg of levothyroxine PO daily. The medication is labeled, "50 mcg tablets." How many tablets should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["1.5"]

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:

75 mcg/ x tablet  ​= 50 mcg/1 tablet ​

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

Cross-multiplying and solving for x:

X = 75 mcg×1 tablet​/50 mcg

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 ["2000"]

Explanation

Here's how to calculate the total milligrams of ampicillin the child should receive per day:

Convert child's weight to kilograms:

Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)

Weight (kg) = 88 lbs / 2.205 lbs/kg

Weight (kg) = 40 kg (round to nearest whole number)

Calculate the total daily dosage:

Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)

Daily dosage (mg) = 50 mg/kg/day * 40 kg

Daily dosage (mg) = 2000 mg

Therefore, the child should receive 2000 mg of ampicillin per day.

Correct Answer is ["120"]

Explanation

Here's how to calculate the rate (mL/hour) for the infusion pump to deliver lidocaine 4 mg/minute:

1. Lidocaine concentration:

The medication bag contains 1 gram of lidocaine in 500 mL of dextrose 5% in water.

Convert grams to milligrams: 1 gram = 1000 milligrams

Lidocaine concentration (mg/mL) = Total lidocaine (mg) / Volume (mL)

Lidocaine concentration (mg/mL) = 1000 mg / 500 mL

Lidocaine concentration (mg/mL) = 2 mg/mL (round to nearest whole number)

2. Prescribed lidocaine dose: 4 mg/minute (given)

3. We need to find the volume delivered per hour (mL/hour) to achieve the prescribed lidocaine dose (4 mg/minute) considering the concentration (2 mg/mL) in the bag.

Infusion rate (mL/hour) = Dose (mg/minute) x Minutes per hour / Concentration (mg/mL)

However, there's a mismatch in units between dose (mg/minute) and concentration (mg/mL).

To address this, we can convert the infusion duration (minutes) to hours to match the concentration units (mg/mL).

Conversion factor: 60 minutes/hour

Infusion rate (mL/hour) = Dose (mg/minute) x (60 minutes/hour) / Concentration (mg/mL)

Infusion rate (mL/hour) = 4 mg/minute * 60 minutes/hour / 2 mg/mL

Infusion rate (mL/hour) = 120 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver approximately 120 mL/hour.
