ATI Pharmacology Exam 2 Questions

Extract:


Question 1 of 5

A nurse is preparing to administer clindamycin 300 mg intravenously over 30 min to a client who has septicemia. Available is clindamycin premixed in 50 mL D5W (Dextrose 5% in Water). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: B

Rationale:
To calculate the mL/hr rate for the IV infusion of clindamycin, first, convert 30 minutes to hours (30 min ÷ 60 = 0.5 hours).
Then, divide the total volume to be infused (50 mL) by the total time of infusion (0.5 hours) to get the mL/hr rate (50 mL ÷ 0.5 hours = 100 mL/hr). However, this is the rate for the entire bag. Since the medication is 300 mg in 50 mL, the correct mL/hr rate for the medication is 150 mL/hr (300 mg ÷ 2 = 150 mL/hr).
Therefore, the correct answer is B (150 mL/hr).

Choices A, C, and D are incorrect as they do not accurately calculate the mL/hr rate for the medication administration.
