Increased cortisol secretion C. Increased growth hormone secretion D. Hyperpigmentation r a. QUESTION 21Explanation / Answer
19 Answer is (b). because
Pheochromocytoma is tumor of chromaffin cells in adrenal medulla. Adrenal medulla plays an important role in synthesis and secretion of catecholamines (epinephrine and norepinephrine). In pheochromocytoma, these hormones are overproduced. Increase in these hormones in turn increase the blood pressure. Therefore primary intervention is by monitoring the blood pressure of the patient.
Alphablockers are first administered and the beta blockers are administered to render the body less sensitive to these hormones.
33 . Answer (B): Respiratory acidosis.
Acid-base balance is maintained by coordinated effect of kidney and lungs. Reference range in normal body is; arterial blood pH; 7.35-7.45 and pCO2 is 35-45mmHg. As the pCO2 levels are increased and pH is decreased, it is case of respiratory acidosis. It is a condition in which blood carbon dioxide is increased, which causes blood pH to decrease.
20. Answer (b).
Cortisone stimulates the adrenal gland to produce cortisol.
34. Answer (A) .
Decreased blood pressure increases the release of ADH, rennin and aldosterone which in turn causes kidney to concentrate urine by increasing its solute content. In this case also the levels of rennin, ADH, aldosterone are increased a which is likely cause of hypernatremia.
Nephrogenic Diabetes inspidus is caused by defect in kidney tubules thereby kidney is not able to concentrate urine. Large volume of water/ urine is excreted out. Hypernatremia is caused in this case.
While central diabetes inspidus is characterized by decreased secretion of ADH. It is caused due to damage to hypothalamus or pituitary gland. This in turn causes increased excretion of fluid from body.
Inappropriate ADH syndrome is characterized by continued secretion of ADH but hyponatremia is observed.
