Final answer:
For individuals with more subcutaneous tissue than average, a 90 degree insertion angle for injections is recommended over the standard 45 degree angle.
Step-by-step explanation:
When administering injections to an individual with a greater than average amount of subcutaneous tissue, the angle of insertion may need to be adjusted. While a 45 degree angle is often suitable for adults with an average amount of subcutaneous tissue, for those with more tissue, a 90 degree insertion angle is typically recommended. This is to ensure that the medication is delivered to the correct tissue layer for absorption.
A 60 degree insertion angle is less commonly used and may not provide the appropriate depth for certain types of injections, particularly in individuals with increased subcutaneous tissue. Intramuscular injections are a different method of drug delivery and involve depositing medication deeply into muscle tissue, which can be considered when applicable but is not directly related to the adjustment of the angle for subcutaneous injections.
