Why Injections & Medication Administration matters

Injections & Medication Administration is one of the most tested areas because medication errors are among the most preventable causes of patient harm.

Sample Practice Questions (5)

1. A patient on warfarin therapy requires a subcutaneous injection. Which precaution is MOST important for the MA to take?

  • Apply firm pressure to the site for 3-5 minutes after injection without rubbing
  • Use a larger gauge needle to minimize tissue trauma
  • Aspirate before injection to confirm the needle is not in a blood vessel
  • Refuse to administer the injection until the INR is checked

2. A patient with type 1 diabetes asks the medical assistant about insulin injection site rotation. The MA should instruct the patient to:

  • Rotate within the same anatomical area (e.g., abdomen) using a systematic pattern, spacing injections at least 1 inch apart
  • Use the same exact spot each time for consistent absorption rates
  • Switch between the arm and thigh with each injection regardless of pattern
  • Inject only in the abdomen because other sites are unsafe for insulin

3. A subcutaneous injection is administered at what angle?

  • 45 degrees
  • 90 degrees
  • 10-15 degrees
  • 60 degrees
