Correct Answer is A

Explanation

To calculate the dose in milligrams per hour, we need to convert the patient's weight from pounds to kilograms.

Patient's weight: 110 lb

To convert pounds to kilograms, we use the conversion factor: 1 lb = 0.4536 kg

Patient's weight in kilograms: 110 lb * 0.4536 kg/lb = 49.895 kg (rounded to 3 decimal places

The physician has ordered Dobutamine at a dose of 10 mcg/kg/min.

Dose required = 10 mcg/kg/min * 49.895 kg = 498.95 mcg/min

Next, we need to convert the dose from micrograms to milligrams.

498.95 mcg/min = 0.49895 mg/min

Finally, to determine the dose in milligrams per hour, we multiply the dose in milligrams per minute by 60 minutes to convert it to an hourly rate.

0.49895 mg/min * 60 min/hr = 29.937 mg/hr (rounded to 3 decimal places)

Therefore, the correct answer is:

a. 30 mg/hr

A. Administer 0.5 mL of medication immediately to the client B. Administer 25 mg of medication once a day to the client for two weeks C. Administer 25 mg of medication every eight hours D. Administer 0.5 mL of medication if the client has symptoms of allergy E. Administer 0.5 mL of medication if the client has symptoms of allergy

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.
