Why is subcutaneous (SC) insulin usually administered into the abdomen as the preferred site?
There are fewer insulin side effects when given in this site.
It is the least painful location for this injection.
There is steady absorption of insulin from this site.
It causes less bruising at the site.
The Correct Answer is C
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.

Correct Answer is A
Explanation
When calculating a pediatric dose from an adult dose, using the child's body surface area (BSA) is a more accurate method. BSA takes into account both the child's weight and height, which are important factors in determining the appropriate dose.
Body surface area can be calculated using various formulas, such as the Mosteller formula (BSA = √[height (cm) x weight (kg) / 3600]) or the Du Bois formula (BSA = 0.007184 x [height (cm)]^0.725 x [weight (kg)]^0.425).
By considering the child's BSA, the dose can be adjusted more precisely to account for differences in body composition and metabolic rate compared to adults. This helps to ensure that the child receives an appropriate and safe dosage.
Options b, c, and d (ideal body weight, actual body weight, actual body height) alone may not provide an accurate calculation for pediatric dosing, as they do not account for variations in body size and composition among children of different ages and developmental stages. BSA takes into consideration both weight and height, providing a more reliable basis for dose calculation in pediatrics.
Therefore, the accurate method for calculating the child's dose when confirming a pediatric dose from an
adult dose is to use body surface area (BSA).
Correct Answer is D
Explanation
The patient received heparin at a rate of 12 mL/hr for 2 hours (from 9:00 am to 11:00 am) and then at a rate of 10 mL/hr for 3 hours (from 11:00 am to 2:00 pm). The total volume of heparin solution infused is (12 mL/hr x 2 hr) + (10 mL/hr x 3 hr) = 54 mL. Since there are 25,000 units of heparin in 250 mL of solution, the concentration of heparin is 25,000 units / 250 mL = 100 units/mL. Therefore, the total amount of heparin received by the patient is 54 mL x 100 units/mL = **8900 units**.
A. 5400 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
B. 6800 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
C. 7200 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
