Here are the answers to all 17 pharmacology MCQs from the PDF, with brief rationale:
1. Pheochromocytoma - preoperative management b. Start Phenoxybenzamine first, followed by Propranolol if needed Alpha-blockade (phenoxybenzamine) must precede beta-blockade to prevent unopposed alpha-mediated vasoconstriction and hypertensive crisis if a beta-blocker is given first.
2. Hypotension with marked bradycardia a. Dopamine Dopamine has alpha, beta-1, and dopaminergic activity - it raises both heart rate/contractility (beta-1) and blood pressure (alpha), unlike noradrenaline/phenylephrine which are pure alpha-agonists and can cause reflex bradycardia.
3. Chronic gout, long-term use after acute attack resolves a. Allopurinol Xanthine oxidase inhibitor for long-term urate-lowering prophylaxis; never started during an acute flare.
4. Resting tremor 3 weeks after starting psychiatric medication a. Typical antipsychotics D2 receptor blockade in the nigrostriatal pathway produces drug-induced parkinsonism (tremor, rigidity, bradykinesia).
5. Pulmonary arterial hypertension c. Bosentan Endothelin receptor antagonist that reduces pulmonary vascular resistance/pressure.
6. SLE - long-term disease control a. Hydroxychloroquine Antimalarial that is the backbone drug for maintenance therapy in SLE, reducing flares and organ damage over time.
7. Hypertensive emergency (230/110, headache, blurred vision, end-organ damage) c. Sodium nitroprusside Rapid-acting IV vasodilator, titratable, drug of choice for hypertensive emergencies.
8. Bipolar disorder - maintenance therapy a. Lithium First-line mood stabilizer for long-term prophylaxis of manic and depressive episodes.
9. Triptans - mechanism b. 5-HT₁B/5-HT₁D receptor (agonist) Causes cranial vasoconstriction and inhibits release of vasoactive neuropeptides, aborting acute migraine attacks.
10. Multibacillary leprosy - WHO MDT regimen (adult) b. Rifampicin 600 mg once monthly (supervised) + Clofazimine 300 mg once monthly (supervised) + 50 mg daily + Dapsone 100 mg daily, for 12 months
11. Lineweaver-Burk plot - uncompetitive inhibition
I viewed the graph image on that page. The four quadrants show:
  • Top-left: lines intersect on the y-axis (same Vmax, different Km) → competitive inhibition
  • Top-right: two parallel lines (same slope, inhibitor line shifted up/left, no intersection point) → this is the classic signature of uncompetitive inhibition, where both Km and Vmax decrease proportionally
  • Bottom-left: lines with negative slope converging on the x-axis (same Km, different Vmax) → pure noncompetitive inhibition
  • Bottom-right: lines intersecting to the left of the y-axis, above the x-axis → mixed inhibition
Answer: the top-right graph (parallel lines) represents uncompetitive inhibition.
12. Aspirin (salicylate) overdose - enhancing elimination b. IV sodium bicarbonate to achieve urinary alkalinization Alkalinizing the urine ion-traps salicylate (a weak acid) in its ionized form, markedly increasing renal excretion. (Charcoal/lavage only help early gastric decontamination, not elimination once absorbed; N-acetylcysteine is for paracetamol, not aspirin.)
13. LOX pathway - selective cysteinyl leukotriene (CysLT1) receptor blocker b. Montelukast (Zileuton inhibits 5-lipoxygenase itself rather than blocking the receptor.)
14. Chlorthalidone-induced hyperglycemia mechanism a. Chlorthalidone causes hypokalemia, which reduces insulin secretion from pancreatic beta-cells This hypokalemia-mediated impairment of insulin release is the accepted mechanism for thiazide/thiazide-like diuretic hyperglycemia.
15. Trauma with hemoperitoneum, hypotensive/tachycardic - induction agent d. Ketamine Preserves sympathetic tone and blood pressure (unlike propofol/thiopentone, which cause vasodilation and myocardial depression that would worsen hypovolemic shock).
16. Multiple myeloma - proteasome inhibitor a. Bortezomib
17. Tumor lysis syndrome - rapid lowering of serum uric acid b. Pegloticase Among the listed options, pegloticase is a PEGylated recombinant uricase that enzymatically degrades existing uric acid to allantoin, acting rapidly - the same mechanism class as rasburicase (the true first-line drug for TLS, though not listed here). Allopurinol/febuxostat only block new urate production (xanthine oxidase inhibitors) and act too slowly for an emergency; probenecid increases renal urate excretion and is actually contraindicated in TLS (risk of intratubular urate precipitation).
18. Bipolar patient, 6 months of treatment: tremor, polyuria/polydipsia, weight gain, hypothyroidism c. Lithium Classic chronic lithium toxicity/side-effect profile: fine tremor, nephrogenic diabetes insipidus (polyuria/polydipsia), weight gain, and hypothyroidism (inhibits thyroid hormone release).
A couple of notes on the file: pages 15 and 18 each had a blank option "e." with no text, and page 1 was blank (likely a title page) - these didn't affect the answers above. If you want, I can also format this into an answer key/PDF for printing.

15 explain

Question 15 recap: A 28-year-old man post-RTA, pale, diaphoretic, hypotensive (BP 75/50), tachycardic, with a ruptured spleen and massive hemoperitoneum, is going for emergency exploratory laparotomy. Which induction agent is most appropriate? a. Sevoflurane b. Propofol c. Thiopentone sodium d. Ketamine
Answer: d. Ketamine
Why Ketamine is correct:
This patient is in hypovolemic/hemorrhagic shock - he has lost a large volume of blood into the peritoneal cavity, and his body is compensating with tachycardia and peripheral vasoconstriction to maintain whatever blood pressure it can. Any induction agent chosen has to avoid tipping this fragile compensated state into cardiovascular collapse.
Ketamine is unique among IV/inhalational induction agents because it is sympathomimetic: it inhibits the reuptake of noradrenaline centrally and peripherally, which causes an increase in heart rate, blood pressure, and cardiac output rather than a decrease. This makes it the induction agent of choice in patients who are already hypotensive or hypovolemic (trauma, tamponade, severe sepsis) because it helps preserve perfusion pressure during induction rather than worsening the shock.
It also has minimal effect on respiratory drive and preserves airway reflexes reasonably well compared to other agents, which is useful in an emergency, non-fasted trauma patient.
Why the others are wrong:
  • b. Propofol - causes significant dose-dependent vasodilation and myocardial depression, dropping preload and cardiac output further. In a hypovolemic patient this can precipitate profound hypotension or cardiovascular collapse on induction.
  • c. Thiopentone sodium - a potent myocardial depressant and venodilator; in a volume-depleted patient with reduced compensatory sympathetic reserve, it can cause a severe, sometimes fatal, drop in blood pressure. Thiopentone is particularly dangerous in hypovolemic/shock patients.
  • a. Sevoflurane - a volatile inhalational agent, not typically used for rapid-sequence induction in an emergency trauma case; it also causes dose-dependent vasodilation and myocardial depression, and takes longer to secure a controlled airway (important in a non-fasted, high-aspiration-risk trauma patient).
Clinical teaching point: Ketamine (and to a lesser extent, etomidate, which maintains hemodynamic stability by having minimal cardiovascular effects) are the preferred induction agents in hemodynamically unstable/hypovolemic trauma patients. Propofol and thiopentone should generally be avoided or used at markedly reduced doses in this setting because of their hypotensive effects.

All 15 forensic medicine & toxicology (FMT) MCQs answered, with the image-based questions confirmed from the actual images:
1. Stab wound with one acute angle + one blunt angle a. Single-edged knife A single-edged weapon has a sharp cutting edge (produces the pointed/acute angle end) and a blunt back edge (produces the rounded/blunt angle end) as it's withdrawn. A double-edged dagger would produce a wound with two acute angles on both ends.
2. Right-handed person, multiple parallel cuts on left wrist a. Suicidal Multiple parallel, superficial "hesitation/tentative cuts" of similar depth on the wrist contralateral to the dominant hand (right-handed person cutting the left wrist, which is accessible and typically the non-dominant side) are the classic pattern of self-inflicted (suicidal) injury.
3. Both lung and liver fail to float in water c. Respiration absent; decomposition absent Lung floatation assesses whether the baby breathed (aerated lungs float; unaerated/fetal lungs sink → no respiration). Liver floatation assesses putrefaction (gas-filled, decomposed liver floats; a liver that sinks means decomposition has not set in).
4. Motile spermatozoa on vaginal wet mount a. 12-24 hrs Motile sperm generally do not persist beyond roughly this window in vaginal secretions (non-motile sperm can be detected much longer, up to 72+ hours). Finding motile sperm places the assault within this more recent timeframe.
5. Able to have intercourse generally, but not with one particular woman a. Quoad hanc Latin for "as regards this woman" - selective/partner-specific impotence, as opposed to true organic impotence.
6. MTP consent at 10 weeks, married woman a. Only the woman Under the MTP Act (India), only the pregnant woman's own written consent is required for termination - husband's consent is not legally necessary, regardless of marital status.
7. Unconscious → lucid interval → neurological deterioration a. Linear fracture This is the classic history of extradural (epidural) hematoma, most often from a linear fracture of the temporal bone tearing the middle meningeal artery.
8. Mustard oil adulteration a. Argemone oil Argemone mexicana ("Mexican prickly poppy") seed oil contaminating mustard oil causes epidemic dropsy (sanguinarine-induced capillary damage).
9. Choking while eating, image shows universal choking sign a. Heimlich maneuver Conscious adult with complete/severe airway obstruction (unable to speak) → abdominal thrusts (Heimlich maneuver) is the immediate first-line action.
10. Child with anemia, wrist drop, stippled peripheral smear b. Lead poisoning The smear shows basophilic stippling of RBCs, classic for lead poisoning; wrist drop results from radial nerve-associated motor neuropathy of chronic lead toxicity.
11. Skull fracture image (round, punched-out defect) a. Bullet A clean, round, punched-in defect through the calvarium is most consistent with a gunshot entrance wound; blunt trauma produces irregular/depressed comminuted fractures, sharp weapons produce linear/slit defects, and pointed weapons produce smaller puncture-type defects.
12. Skull with history of neurosurgery, circular defect c. Previous burr hole surgery The smooth, regular, healed-margin circular defect with a known neurosurgical history is a burr hole, not a fresh traumatic injury.
13. Ricin mechanism of toxicity b. Inhibition of protein synthesis Ricin's A-chain enzymatically inactivates the 28S ribosomal RNA subunit, halting the elongation step of protein synthesis - it's one of the most potent protein synthesis inhibitors known.
14. Retained surgical gauze → sepsis → death b. Never event Retained foreign objects after surgery are specifically classified by the National Quality Forum as "Never events" - serious, largely preventable incidents that should never occur with proper safety protocols (a subtype of sentinel event, but the specific standard term tested here is "never event").
15. Elbow X-ray - age estimation c. 14-16 years The image shows well-formed epiphyses at the elbow (capitulum, radial head, medial epicondyle, olecranon) with visible but thinning growth plates approaching fusion - consistent with the CRITOE ossification sequence at mid-to-late adolescence, where the medial epicondyle and olecranon (the last centers to fuse) are present but not yet fully united, placing the age around 14-16 years.
A note on limitations: for questions 3 and 4, the source material referenced a "video" rather than a static image, so I answered from standard forensic medicine teaching (Reddy's/Parikh's textbooks) rather than direct visual confirmation. If you have the actual video frames, I'm happy to re-check those two.
