The nurse instructs the patient to insert the needle at a 90-degree angle to inject insulin into subcutaneous tissue because the patient is obese and likely to have excessive abdominal adipose tissue.The 5/8-inch needle is long enough to reach subcutaneous tissue for proper administration of insulin but not long enough to reach muscle.The nurse instructs the patient to remove all air bubbles from the syringe before administering the insulin.Aspiration is unnecessary for subcutaneous injections because the tissue is avascular.A 1-inch needle is unnecessary because a 5/8-inch needle reaches the same subcutaneous tissue in this patient as a 1-inch needle.
