Correct Answer - A
Ans: A. PICA
. Most cases result from ipsilateral vertebral artery occlusion;
occlusion of the posterior inferior cerebellar artery is responsible for
it.
Vessel occlusion that results in Lateral Medullary syndrome:
Vertebral (most common)
Posterior inferior cerebellar (2nd most common)
Superior, middle or Inferior lateral medullary arteries
Lateral medullary syndrome (Wallenberg syndrome):

Correct Answer - A
Ans: A. (Lymphocytosis, Low Glucose, High protein)
Presence of significant basal exudates, together with dilated
ventricles (hydrocephalus) in a young female with
a prolonged history of fever and headache suggests a diagnosis of
Tubercular Meningitis.
Tubercular Meningitis is characterized by Lymphocytic Pleocytosis,
Low Glucose and High Protein within the CSF.
The pathological hallmark of Tubercular Meningitis is the
predominant involvement of basal cisterns that are observed by the
presence of basal inflammatory tissue exudate.

Correct Answer - A
Answer- A. Williams syndrome
In the severe form, Prenatal and postnatal growth failure are
common and number of phenotypic features of Williams syndrome
are observed in some of the patients include cardiovascular
abnormalities (usually supravalvular aortic stenois and peripheral
pulmonic stenosis), late psychomotor development, selective mental
deficiency, a characteristic unusual facies and short stature.
The serum calcium levels range between 12 - 19mg/ dL.

Correct Answer-B
Ans. is 'b' i.e., Aplastic crisis
. Parvovirus B19 selectively infects erythroid precursors and is the
most common aetiological agent that induces
. aplastic crisis in patients with hereditary spherocytosis (and other
Hemolytic disorders).
Transient aplastic crisis
. Persons with decreased erythrocytes caused by conditions such as
iron deficiency anemia, human immunodeficiency virus sickle cell
disease, spherocytosis or thalassemia are at risk of transient
aplastic crisis if infected with parvovirus B19.
. The virus causes a cessation of erythrocyte production.
. Parvovirus infection may be the first manifestation in HS
• It begins with reticulocytosis and thrombocytosis

Correct Answer - A
T wave inversion develop after ST elevations return to baseline.
There are four stages of ECG changes in the evolution of acute pericarditis. In stage 1,
there is widespread elevation of the ST segments, often with upward concavity, involving
two or three standard limb leads and V2 to V6, with reciprocal depressions only in aVR and
sometimes V1, as well as depression of the PR segment Usually there are no significant
changes in QRS complexes. In stage 2, after several days, the ST segments return to
normal, and only then, or even later, do the T waves become inverted (stage 3). Ultimately,
weeks or months after the onset of acute pericarditis, the ECG returns to normal in stage 4.

An elderly diabetic female has presented with muliplk episodes of vomiting after few hours of consumin food from outside. On admission BP is low and ABG shows pH 7.5, pC0,= 45 mm Hg and Hco;=] mEq. Na*= 130, K+ = 3.5 and Chloride = 90 mEq'L What is the etiology…Clinical Background:

Elderly diabetic female

Multiple episodes of vomiting after outside food (suggests GI cause)

BP is low → could be hypovolemia or shock

ABG:

pH = 7.5 → alkalosis

pCO₂ = 45 mmHg → normal (suggests this is not respiratory)

HCO₃⁻ = ↑ (implied, though exact value not given) → metabolic alkalosis

---

Electrolytes:

Na⁺ = 130 mEq/L → Mild hyponatremia

K⁺ = 3.5 mEq/L → Low-normal potassium

Cl⁻ = 90 mEq/L → Hypochloremia

---

Interpretation:

pH 7.5 + Normal pCO₂ + High HCO₃⁻ = Metabolic Alkalosis

This matches prolonged vomiting:

Loss of HCl from the stomach → loss of hydrogen ions → metabolic alkalosis

Loss of Cl⁻ → hypochloremia

Volume depletion → hypotension

Kidneys reabsorb Na⁺ in exchange for H⁺ and K⁺ → exacerbates alkalosis and can cause K⁺ loss

Correct Answer - B
Answer is B (Thalamus):
The Amnestic effect in Wernicke's Korsakoff Syndrome is related to
lesions in the dorso-medial nuclei of the thalamus.
`Lesions in the dorsomedial nucleus of the thalamus seem to be the
best correlate of the memory disturbance and confabulation' -
Robbins
