The correct answer for this question is Designed experiment.
A person experiences the placebo effect when their physical or mental health seems to get better after receiving a placebo or "dummy" treatment. A treatment that seems to be real but is intended to have no therapeutic benefit is referred to as a placebo. The Latin word for placebo means "I will please."
One of the most popular hypotheses holds that a person's expectations are what causes the placebo effect. It's possible that the body's chemistry can produce results comparable to what a drug might have produced if a person anticipates a pill to do something.

Answer:
A. 60 cc/hr
B. 00:50 hours
Explanation:
A) How many cc/hr should you set the pump for to keep the IV going at the same rate?
Since we have 60 gtt/cc microdrip tubing and the D5W is running at 60gtt/min.
The number of cc/min = 60 gtt/min ÷ 60 gtt/cc = 1 cc/min
So, the number of cc/hr = 1 cc/min × 60 min/1 hr = 60 cc/hr
B) What time will the infusion be completed?
Since we have 500 cc and an infusion rate of 60 cc/hr, the time taken for the infusion to complete, t = volume/infusion rate = 500 cc ÷ 60 cc/hr = 500/60 = 8¹/₃ hrs = 8 hrs 20 mins.
Since the infusion started at 16:30 hours, 8 hrs 20 mins later is 16:30 + 8:20 = 24:50 hours = 00:50 hours.
So, the infusion will be completed at 00:50 hours.
