  1. What is the correct dose and route of adrenaline for adult anaphylaxis according to DCAS protocols?

    Answer: 0.5mg (500mcg) intramuscularly into the anterolateral thigh

    DCAS protocols specify adrenaline 0.5mg (500mcg) administered intramuscularly into the anterolateral thigh for adult anaphylaxis, as IM provides rapid and reliable absorption.

  2. What is the mechanism of action of salbutamol (Ventolin) used by DCAS paramedics?

    Answer: It relaxes bronchial smooth muscle through beta-2 adrenergic receptor stimulation, causing bronchodilation

    Salbutamol is a selective beta-2 adrenergic agonist that relaxes bronchial smooth muscle, producing bronchodilation and relieving bronchoconstriction in conditions like asthma and COPD.

  3. What are the '5 Rights' of medication administration that DCAS paramedics must follow?

    Answer: Right patient, right drug, right dose, right route, right time

    The 5 Rights ensure medication safety: right patient (verify identity), right drug (check medication), right dose (verify amount), right route (correct administration method), and right time (appropriate timing).

  4. What is the DCAS protocol for administering naloxone in suspected opioid overdose?

    Answer: Administer 400mcg IV/IM/IN, titrate to restore adequate respirations without full reversal

    DCAS protocols recommend naloxone 400mcg administered IV, IM, or intranasally, titrated to restore adequate respiratory function. Full reversal is avoided to prevent acute withdrawal symptoms.

  5. What is the indication and dosing of aspirin in DCAS chest pain protocols?

    Answer: 300mg chewed for suspected acute coronary syndrome to inhibit platelet aggregation

    Aspirin 300mg chewed (for rapid absorption) is administered for suspected ACS to inhibit platelet aggregation and reduce thrombus formation, unless the patient is allergic or actively bleeding.

  6. What precautions must DCAS paramedics take when administering glyceryl trinitrate (GTN)?

    Answer: Check systolic BP is above 90mmHg, ask about phosphodiesterase-5 inhibitor use within 48 hours, and monitor for hypotension

    GTN must not be given if systolic BP is below 90mmHg or if the patient has used PDE-5 inhibitors (sildenafil/tadalafil) recently, as the combination can cause dangerous hypotension.
