Introduction to Sterile Technique, Skin and Joint Injections

Quiz yourself on critical terms and concepts related to sterile technique and the administration of skin and joint injections.

Universal Precautions

A system of infection control that treats all human blood and potentially infectious materials as if known to be infectious.

Aseptic Technique

A method that involves using barriers to prevent the transfer of microorganisms during procedures.

Sterile Technique

An approach that requires the complete absence of microorganisms; used in operating rooms.

Needle Stick Injury (NSI)

A break in the skin from a needle or other sharp object, posing a risk of transmitting infections.

Complications of Injections

Adverse effects that can occur, including allergic reactions, infection, and injection site reactions.

Informed Consent

Documentation that includes patient education on indications, risks, and alternatives before a procedure.

Intramuscular (IM) Injection

An injection administered into muscle tissue, typically at a 90° angle for rapid absorption.

Subcutaneous (SQ) Injection

Intradermal (ID) Injection

An injection administered just under the skin, primarily for diagnostic purposes.

Z-Track Technique

A method used for IM injections to prevent medication leakage by pulling the skin aside before injection.

Other Potentially Infectious Materials (OPIM)

Biological materials that may contain pathogens, such as body fluids that are visibly contaminated with blood.

Clean Technique

A method that reduces the number of microorganisms to minimize infection risk during procedures.

Injection Supplies

Necessary materials for injections, including syringes, needles, alcohol, and gloves.

Post-Procedure Care

Instructions given to patients after a procedure, including signs of infection to monitor.

Joint Aspiration

The process of removing fluid from a joint for diagnostic or therapeutic purposes.
