DCAS Pharmacology and Drug Administration

Question 1

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

Accepted Answer

0.5mg (500mcg) intramuscularly into the anterolateral thigh

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

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

Answer

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).

Question 4

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

Accepted Answer

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

Answer

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.

Question 5

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

Accepted Answer

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

Answer

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.
