Stabbed left 5th intercostal space at edge of sternum, which most likely to be penetrated
D. R ventricle
Extensive bleeding from glass injury to arm. O/e 7cm transverse laceration across anterior aspect of elbow - exploring cubital fossa, expect brachial artery to be
A. lateral to medial nerve
Borders cubital fossa
(3 borders, roof, floor)
- Lateral border – medial border of brachioradialis m.
- Medial border – lateral border of pronator teres m.
- Superior border – horizontal line drawn between the epicondyles of humerus
- Roof – bicipital aponeurosis, fascia, subcutaneous fat and skin.
- Floor – brachialis (proximally) and supinator (distally)
ICU admission, isolated severe head injury, multiple intracebral bleeds but no midline shift.
I+V, pupils react sluggishly to light.
HR 50, BP 170/110, RR set at 10.
Rising blood pressure likely caused by:
D. sympathetic stimulation related to intracranial pressure
Relation of ureter to gonadal vessels at pelvic brim
posterior to it
Relation of ureter to renal a.

How to identify uncinate process

patient with signs of facial and trigeminal nerve palsy - where's level of tumour compression
pons
Pt cannot dorsiflex big toe - which nerve root likely involved
L5
Pt had cholecystectomy and develops self-limiting postop wound infection. By what process would bacterial infection have been enhanced?
D. opsonisation
immune process which uses opsonins to tag foreign pathogens for elimination by phagocytes
(or longer: Opsonization (also, opsonisation) is the molecular mechanism whereby pathogenic molecules, microbes, or apoptotic cells (antigenic substances) are connected to antibodies, complements, or other proteins to attach to the cell surface receptors on phagocytes and NK cells.)
pericardiaoperitoneal membrane defect will lead to
A. Congenital diaphragmatic hernia
B. actopia cordis
A. Congenital diaphragmatic hernia
Facial nerve transection during parotidectomy will lead to
C. lower lip drooping
post parotidectomy, pt developed gustatory sweating during meals, what is mechanism
regeneration of parasympathetic fibersof auriculotemporal n. into sympathetic fibres innervating sweat gland
(these short q? -> so obscure, will look for related info later)
pt with pancreatitis, what enzyme responsible for autodigestion
B. trypsin
(general consensus that the initial pathogenic event in acute pancreatitis is intraacinar activation of trypsinogen into trypsin, followed by that of the remaining proenzymes, giving rise to an unusual model of autophagic inflammation)
Large fluctuant swelling at site of recent insect bite - would need surgical drainage. Anxious, tachycardia, pyrexia. ECG - critical fibrillation, noted to have a goiter. Which class of drug most appropriate as part of pre-op prep for surgery?
A. beta adrenoceptor blocker
(frigging, b blocker)
multiple peripheral fractures, clinically shocked. Which structure responsible for 1st haemostatic response to a fall in systemic arterial BP?
C. baroreceptor
(1st)
Failure of caudal part of metanephron to develop will result in
C. renal agenesis
pt falls onto wrist, resulting in median nerve injury
due to lunate dislocation
* to look up
which of following is required to be divided during tracheostomy
B. thyroid isthmus (isthmus of thyroid gland)
45yo established cirrhosis. At f/u palpable spleen 4 finger breaths below costal margin. FBC shows persistent thrombocytopenia. Bone marrow exam shows megakaryocyte hyperplasis. What most likely cause of thrombocytopenia?
E. platelet destruction in spleen
branchial cyst derived from which pharyngeal arch
B. second
(b - bạc, second)
- An oval, mobile cystic mass
- between sternocleidomastoid muscle & pharynx
- due to failure of obliteration of the second branchial cleft in embryonic development
- Usually present in early adulthood
Proximal humerus fractures - how common, usually through where, what most common in children
-very common
-usually through surgical neck
v.rare to have # through anatomical neck
- children: most common injury pattern - greenstick # through surgical neck
Proximal humerus # - when risk of avascular necrosis to humeral head
- impacted #: usu. collar and cuff for 3/52 followed by physiotherapy
- more sign. displaced #: ORIF / IM device
58M with severe burns to his hands. Not distressed by the burns. Has bilateral charcot joints. On examination; there is loss of pain and temperature sensation of the upper limbs. What is the most likely diagnosis?
A) Potts disease of the spine
B) Tabes dorsalis
C) Transverse myelitis
D) Syringomyelia
E) Subacute degeneration of the cord
- Syringomyelia: classical variety spares the dorsal columns and medial lemniscus, affecting only the spinothalamic tract with loss of pain and temperature sensation.
- The bilateral distribution would favor syringomyelia over SCID (spinal cord injury/disorder) or Brown Sequard syndrome.
- Osteomyelitis tend to present with back pain and fever in addition to any neurological signs.
- Epidural haematoma large enough to produce neurological impairment will usually have motor symptoms in addition to any selective sensory loss, and shorter history
