A physician ordered Reglan (metoclopramide) 10 mg to be mixed with 50 mL normal saline and infused over 15 minutes. A nurse must set the IV pump to deliver the medication per mL/hr as ordered.
At what rate should the solution be administered?
200 mL/hr
100 mL/hr
50 mL/hr
300 mL/hr
300 mL/hr
The Correct Answer is A
The physician ordered Reglan (metoclopramide) 10 mg to be mixed with 50 mL of normal saline and infused over 15 minutes. Since the infusion time is 15 minutes (0.25 hours), we can calculate the rate per hour to administer the solution as follows: (50 mL / 0.25 hours) = 200 mL/hour.
B. 100 mL/hr is incorrect because it would take 30 minutes to infuse the solution.
C. 50 mL/hr is incorrect because it would take 1 hour to infuse the solution.
D. 300 mL/hr is incorrect because it would only take 10 minutes to infuse the solution.

Correct Answer is C
Explanation
Subcutaneous (SC) insulin is usually administered into the abdomen as the preferred site because there is
steady absorption of insulin from this area.
The abdomen has a rich blood supply and a relatively higher number of capillaries compared to other subcutaneous sites. As a result, insulin injected into the abdominal subcutaneous tissue is absorbed more consistently and predictably. This allows for better control of blood glucose levels.
A. There are fewer insulin side effects when given at this site: The site of injection does not directly affect the side effects of insulin. Side effects can occur regardless of the injection site and are more related to the medication itself and individual patient factors.
B. It is the least painful location for this injection: The perception of pain can vary among individuals, and the least painful location for an injection may differ from person to person. While some individuals may find the abdomen to be less painful, others may have different preferences or experiences.
D. . It causes less bruising at the site: Bruising at the injection site can occur regardless of the location due to various factors such as needle size, technique, and individual patient characteristics. The choice of injection site does not specifically prevent bruising.
Therefore, the main reason why subcutaneous insulin is usually administered into the abdomen as the preferred site is c. There is steady absorption of insulin from this site, ensuring consistent and predictable insulin delivery for better blood glucose control.
