Common Mistakes: Preparing and Administering an Injection
These are the specific ways this task goes wrong on the job — not hypothetical edge cases, but patterns that cause real documentation errors, billing problems, or patient safety issues.
Drawing up the wrong concentration of a medication that comes in multiple strengths (a well-known source of serious dosing errors).
Using IM technique and needle length for a medication that should be given subcutaneously, or vice versa.
Not rotating sites for patients receiving frequent injections, leading to tissue damage at a single overused site.
Recapping a used needle by hand instead of using a sharps container, risking a needlestick injury.
How the Quality Checkpoints Prevent These
Every mistake above is caught by one of this task's quality checkpoints — the habit of checking these consistently is what actually prevents the error, not just knowing it exists.
- ✓
The five rights (patient, drug, dose, route, time) are checked against the order before drawing up the medication.
- ✓
The vial/ampule is checked for expiration, correct concentration, and clarity before use.
- ✓
Needle gauge and length match both the route and the patient's body size.
- ✓
The patient is observed for a reaction for the period your office protocol requires before discharge.
