Answers to General Surgery Questions

1.d

It is the sudden loss of autonomic tone due to spinal cord injury. Disruption of desceding sympathetic pathway leads to vasodilation and decreased vascular resistance.

Patient has bradycardia and not tachycardia. 

Extremities are warm in these cases.

2. b Septic Shock

The initial inflammatory response to sepsis activates the endogenous release of cortisol, which in turn modulates the synthesis and release of both pro- and anti-inflammatory mediators to restrict inflammation in infected tissues. However, a number of factors, including vascular or ischemic damage, inflammation and apoptosis within the hypothalamic-pituitary adrenal axis, as well as use of drugs that alter cortisol metabolism, may cause adrenal insufficiency

3.a

Point mutations in RET gene gives rise to multiple endocrine neoplasia (MENII) 

This mutation leads to constitutive activation in protein kinase which leads to continuous cell activation

Cytogenetic Location: 10q11.21, which is the long (q) arm of chromosome 10 at position 11.21

4.a

Moh's microsurgery is a tecnique in which cancer removal is done with the minimal defect in the tissues. 2mm margin of skin is removed and submitted for frozen section till a tumor free margin is achieved. 

Melanocytic aytpia is not properly analyzed in frozen section therefore this technique is less applicable in melanoma

5. b

In hyperkalemia bringing back the potassium levels below 5.5 is important to prevent arrythmias. GI (Glucose insulin) drip drives potassium back into the cells from the plasma and decreases serum potassium.

NacL will worsen the metabolic acidosis further.

Calcitonin is used for treating hyppercalcemia
