 * 14) * C - Plasma Na+ concentration is a measure of the action of osmoregulatory mechanisms
 * 15) * D - In patients with central diabetes insipidus, there is no increase in urine osmolality / plasma osmolality ratio above 50% after ADH administration
 * 16) What are the causes of K+ deficiency in the body when vomiting gastric juice?
 * 17) * A - Extrarenal loss of K+, which is contained in a relatively high concentration in acidic gastric juice
 * 18) * B - Dehydration-induced K+ transfer from ECF to ICF
 * 19) * C - Decreased circulating volume with consequent increase in aldosterone secretion and renal urinary K+ loss

Patient in a diabetic coma
A 15-year-old girl is brought in a coma to the Department of Anesthesiology, Resuscitation and Intensive Medicine. She is a diabetic for 7 years, she takes insulin. She already had several bouts of hypoglycemia and ketoacidosis. She's been studying a lot for school lately and may have neglected some insulin injections.

Questions:
 * 1) What is the diagnosis?
 * 2) Calculate the anion gap (AG), what is the cause of high AG?
 * 3) What is the significance of the increased osmolality?
 * 4) Why is chloride and bicarbonate reduced, what is the significance of "normal" sodium and increased potassium?

Obese patient with severe hydration
A 86-year-old woman did not eat or drink fluids for 10 days due to a fever associated with a urinary tract infection and anorexia. Later, she did not eat or drink because she did not leave the bed due to weakness and because she lived alone. A neighbor-called doctor found her in a diseased state and considerable dehydration (dry tongue and mucous membranes, weak skin turgor, she was very thirsty and was breathing fast).

Questions:
 * 1) '''What kind of indoor environment disorder is it?
 * 2) How is the water redistributed in the body of this patient?

Patient with lung cancer
Fifty seven year old male with lung cancer (small cell carcinoma) was examined at check-up. Questions:


 * 1) How do you explain the results of electrolytes and osmolality

Thirty two year old patient
She hasn't been feeling well for about 3 weeks prior to hospitalization. She started vomiting repeatedly about a week prior to hospitalization. She was dehydrated on admission. There was no evidence of hyperglycosuria or ketonuria in the urine.

Laboratory results Questions:


 * 1) Explain the possible cause of the pathological values.

Heart disease patient treated with thiazide diuretics
A 74-year-old man with congestive heart failure was treated with thiazide diuretics and potassium salts. During the last check-up at, he stated that he felt weak and unbalanced when walking.
