  1. Albuterol (salbutamol) works primarily by:

    Answer: Stimulating beta-2 receptors causing bronchodilation

    Albuterol is a beta-2 adrenergic agonist that relaxes bronchial smooth muscle, producing bronchodilation.

  2. Oral glucose (e.g., glucose paste) is indicated for a patient who is:

    Answer: Conscious with confirmed hypoglycemia and able to swallow

    Oral glucose is only safe for conscious patients who can swallow and protect their airway to prevent aspiration.

  3. The antidote for benzodiazepine overdose is:

    Answer: Flumazenil

    Flumazenil is a benzodiazepine receptor antagonist used to reverse benzodiazepine sedation.

  4. Atropine is used in prehospital care primarily to treat:

    Answer: Symptomatic bradycardia

    Atropine is an anticholinergic agent that increases heart rate by blocking vagal tone, used for symptomatic bradycardia.

  5. Which route of administration provides the fastest onset of drug action?

    Answer: Intravenous (IV)

    Intravenous administration delivers the drug directly into the bloodstream, providing the fastest onset of action.

  6. A patient with an organophosphate poisoning would benefit most from which medication?

    Answer: Atropine

    Atropine blocks excessive muscarinic stimulation caused by organophosphate inhibition of acetylcholinesterase.
