(thyrotropin) - 10 mIU/l (N: 0.34–4.25 mIU/l); Thyroxine - 65 nmol/l (N: 70–151 nmol/l). What is the most likely cause of the enlarged thyroid gland in this patient?
Excessive iodine intake
Lack of iodine in water and food
Hereditary disease
Thyroid tumor
Treatment with iodine
Patient V. consulted a doctor with complaints of an enlarged thyroid gland, slight weakness, drowsiness, fatigue, and constipation. She first noticed a slight enlargement of the gland 2 years ago, after moving to this area. During the examination, symmetrical enlargement of both lobes of the thyroid gland was found. Which of the following laboratory values is most typical for hypothyroidism?
Low TSH and high T4
High TSH and low T4
High TSH and high T4
Low TSH and low T4
Normal TSH and T4
A 5-year-old girl is brought to the physician by her mother, who states that she has been drinking a lot of water and urinating more frequently than usual. On physical examination, the girl's eyes are slightly protruding. A head x-ray reveals multiple lytic bone lesions involving the calvaria and skull base, biopsy of which reveals collections of Langerhans cells with intracytoplasmic Birbeck granules. Which of the following sets of laboratory values is most consistent with the expected findings for this girl's disorder?
hypernatremia, low urine osmolarity and specific gravity
hypernatremia, high urine osmolarity and specific gravity
hyponatremia, low urine osmolarity and specific gravity
hyponatremia, high urine osmolarity and specific gravity
normal blood sodium, normal urine osmolarity and specific gravity
Patient V. consulted a doctor with complaints of an enlarged thyroid gland, slight weakness, drowsiness, fatigue, and constipation. She first noticed a slight enlargement of the gland 4 years ago, after moving to this area. During the examination, a symmetrical enlargement of both lobes of the thyroid gland was found. What changes in fat metabolism are possible in the patient?
Increased ketone body levels and normal cholesterol levels
Increased cholesterol and ketone bodies
Normal cholesterol and ketone bodies
Decreased cholesterol levels
Decreased ketone bodies
Patient A., 48 years old. Has suffered from acromegaly for about 7 years. Recently, he began to notice dry mouth, thirst, polyuria, and therefore consulted a doctor. During the examination, hyperglycemia and glucosuria were revealed. What caused the occurrence of these symptoms in this case?
diabetes insipidus
nephrogenic diabetes insipidus
insulin resistance
diabetes mellitus type 1
diabetes mellitus type 2
Which of the following is the MOST important non-immune mechanism of chronic renal failure progression?
reduced load on functioning nephrons
suppression of the kallikrein-kinin system activity
compensatory hyperfiltration in intact nephrons
reduced formation of cytokines and oxygen free radicals
production of autoantibodies against glomerular basement membrane antigens
Which of the following is the MOST important in the pathogenesis of uremia?
impaired filtration and removal of nitrogenous waste from the body
hyperosmolal hyperhydration
development of alkalosis
dehydration of the body
hypercalcemia
Which of the following is the MOST likely complication of hereditary renal phosphate diabetes?
hyperphosphatemia
decreased urinary phosphorus excretion
decreased urinary calcium excretion
demineralization of bone tissue
hyperglycemia
Which of the following is the MOST likely cause of proximal tubular acidosis?
increased ammoniogenesis
decreased tubular secretion of hydrogen ions
excessive reabsorption of sodium ions
decreased ammoniogenesis
impaired reabsorption of bicarbonates
An 18-year-old boy has impaired glomerular function of nephrons. Which laboratory indicator will MOST confirm this pathology?
decreased creatinine clearance
hyposthenuria
isosthenuria
cylindruria
glucosuria
