A 3-month-old boy is brought to the emergency department because of a 20day history of lethargy. Physical examination shows no other abnormalities. The results of laboratory studies are shown: serum: Na+ 165 mEa/L (N=139-146) Cl- 130 mEq/L (N=95-105) Osmolality 334 mOsmol/kg H2O (N=282-295) urine: specific gravity 1.001 osmolality 117 mOsmol/kg H2O (N>200) He is admitted to the hospital. His urine output is increased. His serum ADH (vasopressin) concentraion is 24 pg/mL (N=1-5); aldosterone and renin concentrations are within the reference ranges. The urine osmolality remains unchanges after administration of 1-deamino-B-arginine vasopressin. An MRI of the brain and pituitary gland shows no abnormalities. Ultrasonography shows normal kidneys. The most likely underlying cause of the findings in this patient is a defect in which of the following?a. angiotensin-converting enzyme b. aquaporin c. 11a-Hydroxylase d. renin e. vasopressin receptors
A 68-year old woman presents with hypertension and oliguria. A CT of the abdomen reveals a hypoplastic left kidney. based on the following laboratory data which of the following is her estimated RPF?

A 2-year-old child, admitted to hospital following diarrhoea and vomiting, had the fol- lowing results on analysis of plasma, 24 hours after admission (reference ranges are given in brackets): Sodium (135-145) Potassium (3.5-5.0) Urea (3.5-6.6) Creatinine (70-150) Osmolality (285-305) The urine sodium concentration was 55 mmol/L and its osmolality was 314 mOsm/kg. Comment on these results. 151 mmol/L 3.7 mmol/L 4.9 mmol/L 65 μmol/L 314 mOsm/kg

Patient A is 65 years old female. She has been diagnosed with diabetes Type II. Recently she experienced a gastrointestinal illness with nausea and vomiting. Lab data have been obtained the following day after her illness: Body weight 85 kg; Blood pressure 140/90 mmHg; Blood pH – 7.48; PCO2 – 44 mm Hg; Plasma HCO3 ion -32 mEq/L; Urine pH – 7.5. What is acid-base disorder of this patient. What was a main cause of this? The illness continues and after 2 days the following laboratory data have been obtained: Body weight 83 kg; Blood pressure 120/70 mmHg; Blood pH – 7.50; PCO2 – 48 mm Hg; Plasma HCO3 ion -36 mEq/L; Urine pH – 6.0. Has acid-base disbalance been changed? If yes, what is the explanation for this acid-base disbalance? Is there any compensation?
