A patient presents 6 weeks post-MVA with recurrent intrusive memories, nightmares, avoidance of driving, and hyperarousal. What is the most likely diagnosis?
💡 EXPLANATION:
PTSD is diagnosed when symptoms (intrusion, avoidance, arousal) persist >1 month after trauma. Acute stress disorder is diagnosed when symptoms last 3 days to 1 month. The 6-week duration confirms PTSD.

A 24-year-old patient diagnosed with Obsessive-Compulsive Disorder (OCD) is prescribed fluvoxamine. This medication exerts its therapeutic effect primarily by modulating which neurotransmitter system?
💡 EXPLANATION:
Fluvoxamine is a Selective Serotonin Reuptake Inhibitor (SSRI). OCD pathophysiology is linked to serotonin dysregulation. SSRIs inhibit the reuptake of serotonin (5-HT), increasing its synaptic availability to reduce symptoms.

A 24y M rescued from a house fire presents with 40% TBSA burns. Physical exam reveals carbonaceous deposits in the nares and a hoarse voice. What is the most appropriate immediate management step?
💡 EXPLANATION:
Hoarseness and soot in the nares are classic signs of inhalation injury, posing a high risk for rapid laryngeal edema and airway obstruction. Early prophylactic endotracheal intubation is the priority (Airway) before breathing or circulation interventions.

34y/o M post-RTA. GCS deteriorates from 13 to 9, RR 48/min. What is the most critical immediate intervention?
💡 EXPLANATION:
Rapid GCS deterioration and severe tachypnea indicate impending airway failure. Immediate intubation is required to protect the airway and prevent secondary brain injury before diagnostic imaging (ATLS guidelines).
A 34 y/o M post-RTA deteriorates from GCS 13 to 7. Gurgling sounds are heard on respiration. What is the primary indication for immediate definitive airway management?

A 34 y/o M post-RTA deteriorates from GCS 13 to 7. Gurgling sounds are heard on respiration. What is the primary indication for immediate definitive airway management?
💡 EXPLANATION:
GCS ≤8 with gurgling implies absent protective laryngeal reflexes, creating an immediate risk of aspiration. While ICP control is relevant, protecting the airway from obstruction/aspiration is the primary indication.

A man rescued from a house fire presents with carbonaceous sputum and audible inspiratory stridor. Vitals: BP 115/75, HR 108, RR 26. What is the most critical immediate management?
💡 EXPLANATION:
Stridor and carbonaceous sputum suggest significant inhalation injury with impending upper airway obstruction from edema. Immediate intubation is required to secure the airway before complete occlusion occurs.

A 35 y/o M presents after minor head trauma with isolated retrograde amnesia. GCS is 15/15. There is no history of LOC, vomiting, or focal neurological deficits. What is the most appropriate next step?
💡 EXPLANATION:
NICE guidelines (CG176) state that GCS 15 with isolated retrograde amnesia <30 min does not warrant CT imaging or admission unless other risk factors (vomiting, coagulopathy, age >65) are present. Discharge with written head injury advice is appropriate.

A 24 y/o M presents with agitation, mydriasis, piloerection, and vomiting following abrupt opioid cessation. Which clinical assessment tool is indicated to quantify withdrawal severity?
💡 EXPLANATION:
The Clinical Opiate Withdrawal Scale (COWS) is the validated tool to assess opioid withdrawal severity (signs: mydriasis, piloerection, GI upset) and guide therapy. CIWA-Ar is for alcohol withdrawal; CAGE and AUDIT screen for alcohol use disorder.

Maxemo EMREE 26-27
A patient receives N-acetylcysteine (NAC) for paracetamol overdose. What is the primary mechanism by which NAC prevents hepatotoxicity in this scenario?
💡 EXPLANATION:
Paracetamol toxicity is caused by the metabolite NAPQI when glutathione is depleted. NAC provides cysteine, a precursor for glutathione synthesis, replenishing hepatic stores to neutralize NAPQI.
