Calculate the dose that the nurse should administer to the infant.

A.

0.35 mcg

B.

350 mcg

C.

35 mcg

D.

3.5 mcg

Answer and Explanation

The Correct Answer is A

The nurse should administer 0.35 mcg of medication to the infant.
 
This answer is correct because it is based on a simple multiplication calculation. The nurse should multiply the prescribed dose per kilogram by the infant's weight in kilograms to get the total dose in micrograms, as follows:

0.05 mcg/kg x 7 kg = 0.35 mcg

Therefore, the nurse should administer 0.35 mcg of medication to the infant.

Correct Answer is A

Explanation

To find how much medication to administer, you need to calculate the following:

- The volume of diphenhydramine in milliliters
- The infusion time in minutes

First, divide the dose of diphenhydramine by the concentration to get the volume in milliliters:


25 mg / 50 mg/mL = 0.5 mL diphenhydramine should be diluted in 10 to 20 mL of normal saline and infused over at least 2 minutes.


Therefore, the nurse should administer **0.5 mL** of diphenhydramine diluted in 10 to 20 mL of normal saline over **at least 2 minutes**.


The nurse should administer this medication **as soon as possible** after receiving the order and the medication from the pharmacy, as STAT means immediately or urgently. The nurse should also monitor the client for signs of improvement or adverse reactions.

Correct Answer is C

Explanation

To find the milliliters per minute, you need to calculate the following:

- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)

First, divide the dose of Lopressor by the concentration to get the volume in milliliters:

5 mg / 1 mg/mL = 5 mL

Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:

Infusion rate (mL/min) = Total volume (mL) / Time (min)

Since the total volume is 5 mL and the time is 60 seconds or 1 minute, plug in these values into the formula:

Infusion rate (mL/min) = 5 mL / 1 min

Simplify and solve for the infusion rate:

Infusion rate (mL/min) = 5 mL/min

Therefore, the nurse should administer **5 mL/min** to infuse Lopressor 5 mg over 60 seconds.
