Sites for a subcut injection include the back of the upper arms, the abdomen (but stay a minimum of 2 inches away from the umbilicus), the anterior thighs, the area of the back just below the scapulae, and the upper buttocks The abdomen provides more rapid absorption than the other subcutaneous sites and is the preferred sites for insulin and Lovenox To prevent irritation and tissue damage, the medication must be isotonic and must be the same pH as the tissue. To administer an adult subcut injection, you will need a needle between and inch (0.95 to 2.22 cm) in length with a diameter between 24 and 29 G. You will administer the injection at a 45-degree angle. You will pinch or bunch up the skin and underlying fat layer into a fold between your finger and thumb, which helps to lift the subcutaneous layer off the muscle, helping to ensure that you inject only subcutaneous tissue rather than muscle Do not aspirate before injecting medication as there are few large blood vessels in the subcutaneous tissues, making it difficult to hit a vessel. You will apply gentle pressure to the site after removing the needle and gently massage to distribute the medication into the tissue for better absorption unless you are administering insulin or heparin.

o Insulin is a hormone that is necessary for transporting glucose from the blood into each individual cell of all the tissues in the human body. If insulin is not present to transport the glucose from the blood, the blood level of glucose elevates. Without glucose to utilize for energy production within the cells, all body processes and functions are impaired, which is what happens when an individual has diabetes mellitus: The pancreas does not produce adequate insulin to meet the body’s needs. o Insulin types are designated according to their speed of action, including how long the interval is from administration of the insulin to the onset of its action, the timing of the insulin’s strongest or peak action, and the duration of effect. Classifications generally are categorized as very rapid acting, rapid acting, intermediate acting, long acting, and very long acting. Safety: You will need to learn the onset, peak, and duration of the various insulins so that you can adequately assess patients for effectiveness of their insulin. o Insulin preparations are measured in units and require use of specific insulin syringes for administration. Now most insulin is concentrated at 100 units per milliliter (U-100). Always confirm that you have the corresponding U-100 syringe to use with U-100 insulin. Rapid-acting insulin and short-acting insulin are often combined with intermediate-acting insulins. Not all types of insulins can be mixed. Safety: Long-acting insulins, such as insulin glargine (Lantus), are never mixed with other insulins.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
