ICF ↓ and ECF ↓ ICF ↓ and ECF ↑ ICF no changes and ECF ↓ ICF ↑ and ECF ↓ ICF ↓ and ECF no changes 2/21 ADH level is increased in? decrease in effective blood volume decrease in AngII level decrease in ECF osmolality increase in effective blood volume 3/21 the main mechanism of edema from microvessels damage is? increased hydrostatic pressure of blood capillary decreased lymphatic return decreased plasma colloid osmoticc pressure increased colloid osmotic pressure of interstitial fluid 4/21 hydrops means? the presence of excess body fluid in the interstitial spaces the accumulation of excess body fluid in body cavities the presence of water in body cavities the accumulation of excess body fluid in ECF 5/21 concept of hyperkalemia is serum pottassium level? > 3.5 mmol/L >4.5mmol/L >5.5mmol/L >6.5mmol/L 6/21 shock is the most common manifestation in? isotonic dehydration hypotonic dehydration water intoxication edema hypertonic dehydration 7/21 factors leading to fluid leaving the capillary in excess of the fluid returning back to the blood are? decreased capillary pressure decreased level of ADH decreased level of plasma protein increased level of plasma protein 8/21 which is the main factor determining the volume of ECF? total amount of body water total amount of body sodium the osmolality of ECF total amount of water intake 9/21 what's the mechanism of increased reabsorption of water and sodium in proximal convoluted tubule? increased secretion of natriuretic hormone increased glomerular filtration fraction increased secretion of ADH redistribution of blood flow in kidney 10/21 The characteristics of body fluid imbalance in water intoxication is? volume of ICF ↑ and osmolarity of ECF ↑ volume of ICF ↑ and osmolarity of ECF ↑ volume of ECF ↑, ICF ⇈ and osmolarity of ECF↓, ICF ↓ volume of ECF↓ and osmolarity of ECF↓ 11/21 hyperkalemia can cause? acidosis, with increased secretion of H+ by kidneys acidosis, with decreased secretion of H+ by kidneys alkalosis acidic urine alkalosis alkalinc urine 12/21 plasma osmolality of hypertonic dehydration is? > 25mOsm/L >310mOsm/L >270mOsm/L >290mOsm/L 13/21 in hypotonic hypovolemia serum [Na+] usually is below? 15mmol/L 25mmol/L 35mmol/L 55mmol/L 14/21 plasma osmolality of hypotonic dehydration is below? 310mOsm/L 290mOsm/L 300mOsm/L 280mOsm/L 15/21 what's the major mechanism of edema from retention of sodium and water? decreased GFR increased tubular reabsorption of sodium and water increased production of interstitial fluid increased intake of water 16/21 to the hypotonic dehydration where is the water loss mainly from? ICF ECF plasma transcelluar fluid 17/21 the internal environment means? ICF ECF transcelluar fluid lymph fluid 18/21 to the hypertonic dehydration where is the water loss mainly from? ICF ECF plasma interstitial fluid 19/21 which is the most prominent manifestation in hypernatremia? peripheral circulatory failure thirsty increased BP nausea and vomit polyuria 20/21 the classification of hypotonic and hypertonic dehydration is based on? total amount of body fluid loss colloid osmotic pressure of ECF cation concentration of ECF crystal osmotic pressure of ECF 21/21 the characteristics of body fluid imbalance in hypertonic dehydration is? ICF ↓ and ECF ↓ ICF ⇅ and ECF ↑ ICF ↓ and ECF ⇊ ICF ⇊ and ECF ↓
