Safe Clinical Skills and Procedures

Framing the domain

This domain tests preparation, technique, and safety checks for common procedures. Questions typically ask what you do first, what you check before proceeding, or what you do when something goes wrong mid-procedure. Competence includes knowing indications, contraindications, complications and your own scope.

Concepts to know

Pre-procedure checks: identity, consent, allergies, indication, site marking where relevant, equipment integrity and expiry. Aseptic technique for invasive procedures. Safe medication and fluid administration including pump programming and line tracing. Urinary catheterisation and catheter-associated infection prevention. Wound care and documentation of wound characteristics. Venepuncture and cannulation complications (infiltration, extravasation, phlebitis). Oxygen delivery devices and humidification. Suction and airway adjuncts within scope. Post-procedure monitoring and documentation.

Common traps

  • Proceeding without confirming identity, consent or allergy status.
  • Failing to trace lines and pumps to the correct patient and site before administering.
  • Ignoring pain, swelling or resistance during infusion, which may signal extravasation.
  • Inserting a catheter without a documented ongoing indication.
  • Performing a procedure outside your competence without supervision.

Rule of thumb and worked example

Rule of thumb: pause at the point of care and confirm identity, indication, consent and equipment before you begin - a ten-second check prevents most procedural harm.

Worked example: During IV antibiotic administration, the patient reports burning at the cannula site and the surrounding skin is cool and swollen. Stop the infusion immediately, do not flush, disconnect and aspirate per policy if extravasation is suspected, elevate the limb, escalate to the treating team, document findings and time, and report the incident. Restarting the infusion through the same device would be unsafe.
