Final answer:
In a subcutaneous injection, you should not inject air bubbles. Pinching the skin tightly and massaging the site post-injection can be correct techniques, depending on the medication and guidelines.
Step-by-step explanation:
When giving a subcutaneous (subQ) injection, you should not inject air bubbles. While aspirating before injecting is not typically necessary for subQ injections, making sure that there are no air bubbles in the syringe prior to injection is important. Injecting air into the tissue can cause air embolism or interfere with the delivery of the medication. Pinching the skin tightly is an appropriate step to ensure a proper 'tent' is made in which to administer the medication. Massaging the injection site after injection can be appropriate for some medications to assist with dispersion and absorption. However, massaging depends on the type of medication administered and professional guidelines should be followed.
