What is the first-line treatment for anaphylaxis?

Accepted Answer

Intramuscular adrenaline (epinephrine) 0.5mg (1:1000) into the anterolateral thigh

Question 2

What is the emergency treatment for hypoglycemia in a conscious patient?

Accepted Answer

Fast-acting oral glucose such as glucose tablets, juice, or sugar-containing drinks

Answer

Conscious hypoglycemic patients should receive fast-acting oral carbohydrates (15-20g glucose) followed by a longer-acting carbohydrate snack to prevent recurrence.

Question 3

What is the drug treatment for acute asthma?

Accepted Answer

Inhaled salbutamol (short-acting beta-2 agonist) with systemic corticosteroids for moderate-severe attacks

Answer

First-line treatment includes inhaled SABA (salbutamol) for bronchodilation plus systemic steroids (prednisolone or hydrocortisone) to reduce airway inflammation.

Question 4

What is naloxone used for?

Accepted Answer

Reversing opioid overdose by blocking opioid receptors

Answer

Naloxone is an opioid antagonist that rapidly reverses respiratory depression, sedation, and hypotension caused by opioid overdose.

Question 5

What is the antidote for paracetamol (acetaminophen) overdose?

Accepted Answer

N-acetylcysteine (NAC), which must be given within 8-10 hours for maximum effectiveness

Answer

NAC replenishes glutathione, which is depleted by toxic paracetamol metabolites. Early administration prevents potentially fatal liver damage.
