A nurse is preparing to administer morphine oral solution 30 mg PO for breakthrough pain to a client who has cancer.

Available is morphine oral solution 20 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.5"]

Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 20 mg/mL.

So, we calculate 30 mg ÷ 20 mg/mL = 1.5 mL. Rounded to the nearest tenth, this is 1.5 mL.

So the correct answer is 1.5 mL.

Correct Answer is ["2.1"]

Explanation

First, we need to calculate the total daily dose of tobramycin for the client. The total daily dose is calculated as follows:

Total daily dose = Dose per kg per day x Weight Total daily dose = 3 mg/kg/day x 85 kg Total daily dose = 255 mg/day

Since the total daily dose is divided into three doses, each dose will be:

Each dose = Total daily dose / Number of doses Each dose = 255 mg / 3 Each dose = 85 mg

Now, we need to convert this dose into mL. We know that we have tobramycin 40 mg/mL, so:

Volume to administer = Each dose / Concentration Volume to administer = 85 mg / 40 mg/mL Volume to administer = 2.125 mL

Rounding this to the nearest tenth, we get 2.1 mL.

Correct Answer is ["150"]

Explanation

Step 1 is to determine the rate of infusion. This is done by dividing the total volume by the total time. So, we have 1200 mL ÷ 8 hr = 150 mL/hr.

So, the correct answer is 150 mL/hr.
