Round your answer to the nearest whole number.

Answer and Explanation

The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.

Correct Answer is B

Explanation

To calculate the flow rate in mL/hr for a continuous infusion, we need to divide the total volume to be infused by the total time of infusion, and then convert the units as necessary.

In this case, the total volume is 2.5 L, which is equivalent to 2500 mL (1 L = 1000 mL), and the total time is 15 hours.

Flow rate = Total volume to be infused / Total time of infusion Flow rate = 2500 mL / 15 hours

Flow rate = 166.67 mL/hr

Therefore, the flow rate for continuous infusion of 0.9% sodium chloride solution in this case is 166.67 mL/hr.

A. 5400 units B. 6800 units C. 7200 units D. 8900 units E. 8900 units

Correct Answer is A

Explanation

To calculate the total amount of heparin, we need to multiply the infusion rate by the time and then by the concentration of heparin in the IV bag. From 9:00 a.m. to 11:00 a.m., the infusion rate was 12 mL/hr, so the amount of heparin infused in this period was 12 mL/hr x 2 hours x 100 units/mL = 2400 units.

From 11:00 a.m. to 2:00 p.m., the infusion rate was 10 mL/hr, so the amount of heparin infused in this period was 10 mL/hr x 3 hours x 100 units/mL = 3000 units. The total amount of heparin infused from 9:00 a.m. to 2:00 p.m. was 2400 units + 3000 units = 5400 units.
