ADMINISTRATION OF INTRAVENOUS MEDICATION (VIAL)

This procedure covers administration of a prescribed medication supplied in a vial through an appropriate IV line or infusion system. It emphasises correct preparation, compatibility, aseptic access, prescribed rate and monitoring for local and systemic complications.

Purpose

  • Deliver a prescribed vial medication through the IV route
  • Provide a controlled therapeutic effect when IV administration is indicated
  • Maintain patient safety through line and reaction monitoring

Indications

  • A valid prescription for a medication supplied in a vial for IV administration
  • The medication has been prepared or reconstituted according to authorised instructions
  • The patient has suitable access and the prescribed method is within the nurse's competence

Equipment

  • Prescribed vial medication and medication treatment chart
  • Correct diluent, syringe and needle or approved transfer device
  • Compatible giving set, extension line, infusion pump or rate-control device
  • Antiseptic swabs, sterile dressing and prescribed flush
  • Gloves and PPE according to risk assessment
  • Sharps container, waste receptacle and hand hygiene supplies

Preparation

  • Check patient identifiers, prescription, vial label, concentration, diluent, compatibility, expiry, allergies and route.
  • Inspect the vial and solution for seal damage, leaks, cloudiness, particles or unexpected colour.
  • Explain the medication and monitoring plan, obtain cooperation and ensure the patient can call for assistance.

Procedure steps

  • Perform hand hygiene, identify the patient and prepare the medication in a clean area using aseptic non-touch technique.
  • Reconstitute or dilute the vial only as directed, label the prepared medication if it is not administered immediately and verify the final dose.
  • Prime the compatible giving set or prepare the syringe, removing air without contaminating the sterile parts.
  • Check the IV cannula or line for patency and inspect the site for pain, redness, swelling, leakage or a loose dressing.
  • Disinfect the access port with the approved antiseptic and allow it to dry.
  • Connect the medication or giving set aseptically and set the prescribed rate using an appropriate device.
  • Remain alert to pain, resistance, swelling, rash, wheeze, fever, chills, hypotension or other adverse responses.
  • Stop or manage the medication according to emergency or IV complication protocol and call for help if a serious reaction occurs.
  • At completion, clamp, flush or disconnect only as prescribed, dispose of equipment safely and perform hand hygiene.
  • Reassess the patient and document medication details, time, rate, site, response and any reaction.

Precautions

  • Do not administer medication from a vial with an uncertain label, expiry, appearance or storage history.
  • Check compatibility before adding medication to an infusion and use a separate line when indicated.
  • Do not reuse single-use vials, needles or syringes.
  • Escalate suspected extravasation, phlebitis, infection, medication error or systemic reaction immediately.

Aftercare

  • Keep the patient comfortable and continue observation for the expected monitoring period.
  • Remove or maintain the line according to the prescription and local IV therapy policy.

Nursing considerations

  • Follow local policy for flushing, line access, compatibility, infusion rates and disposal.
  • Use an infusion pump when required for accurate delivery and monitor it according to policy.

Possible complications

  • Medication or concentration error
  • Infiltration, extravasation, phlebitis or infection
  • Rapid adverse drug effect or allergic reaction
  • Air entry or interruption of prescribed therapy

Patient education

  • Ask the patient to report burning, swelling, pain, itching, chills, breathlessness, chest discomfort or dizziness.
  • Explain that the infusion equipment should not be adjusted by the patient.

Documentation

  • Record medication name, dose, concentration, route, start and completion times, rate, site and response.
  • Record any interruption, refusal, adverse effect, batch detail when required and action taken.
