How long is a 25 gauge needle?
½ inch-long
The length of a needle is listed after the gauge number. For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections.
How do you know what size needle to use when injecting?
The needle length and gauge are the same as when the deltoid muscle is used, i.e., 1″–1½” length, 22–25 gauge. You should choose needle length based on the weight of your adult patients, as follows: Adults weighing less than 130 lbs (60 kg): Use of a 1″ needle is recommended.

The length of a needle is listed after the gauge number. For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections.
Do smaller needles hurt less?
The needle’s width, known technically as the gauge, has a lot do with how uncomfortable it feels when it pierces your skin. Not surprisingly, the narrower the needle (which, ironically, means it has a larger gauge number), the less it hurts.
Do you massage after intramuscular injection?
For post-injection care, all evidence directs that clinicians should not massage the injection site.
How deep do you inject intramuscular?
The injection site will be approximately 2 inches below the bone and above the axillary fold/armpit. 3. Administer the vaccine correctly. a 90-degree angle and inject all of the vaccine in the muscle tissue.
What happens if you use a short needle for IM injection?
Medication can be pushed under pressure using a smaller, shorter needle. Use of a small-bore needle significantly decreases the risk of needle trauma because the medication is injected under pressure to travel deep into the tissue rather than the needle traveling deeper into the tissue.
How deep do you go for an IM injection?
Identify the injection site.
The injection site will be approximately 2 inches below the bone and above the axillary fold/armpit.
What size needle is best for IM injections?
