Correct Answer is B

Explanation

We can use the following formula to calculate the infusion time:

Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)

First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:

19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:

Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours

To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:

9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)

Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).

A. 0.2 mL/min B. 0.4 mL/min C. 1 mL/min D. 2 mL/min E. 2 mL/min

Correct Answer is A

Explanation

The patient is ordered to receive 0.3 mg/kg of Nubain IV over 10 minutes. The patient weighs 148 lb, which is equivalent to 67.3 kg. To calculate the total amount of Nubain the patient should receive, multiply the weight by the dosage:

67.3 kg x 0.3 mg/kg = 20.19 mg

The Nubain is available in 10 mg/mL, which means there is 10 mg of Nubain in 1 mL of solution. To calculate how many milliliters of Nubain the patient should receive, divide the total amount of Nubain by the concentration:

20.19 mg / 10 mg per mL = 2.019 mL

To calculate how many milliliters per minute the nurse should administer, divide the total volume of Nubain by the infusion time:

2.019 mL / 10 minutes = 0.2019 mL per minute

Rounding to one decimal place, the nurse should administer 0.2 mL of Nubain per minute to the patient.
