Question

Which form of injection requires the needle to be inserted at a 90 degree angle to the skin?

1) intravenous
2) intramuscular
3) subcutaneous
4) hyperdermic

Answer 1

Intramuscular injection requires the needle to be inserted into the skin at a 90 degree angle to ensure that medication is delivered deep within the muscle tissue for rapid absorption into the bloodstream.

Step-by-step explanation:

The form of injection that requires the needle to be inserted at a 90 degree angle to the skin is an intramuscular injection. This technique is utilized to ensure that the medication is delivered deep within the muscle tissue. Intramuscular injections allow for rapid absorption of the drug into the bloodstream. Other routes of administration, like intravenous or subcutaneous, have different angles of injection to ensure proper placement of the needle and correct delivery of the medication.
