woman 38 ， 2-day history of weakness and postural dizziness（直立性眩晕 ） History：laxative（泻药）abuse with multiple bowel movements each day Physical examination： BP 110/60 mmHg falls to 80/50 mmHg HR 100 beats/min and regular Skin turgor is poor The mucous membrane is dry Case study
Laboratory test Na]=140 mmol/L K+=3.3 mmol/L Cr=116 mmol/L Urine na =9 mmol/L BUN =40 mg/dL Arterial ph=7.25 JHCO3=12 mmol/L aco2=28 mmHg
Laboratory test： [Na+] = 140 mmol/L [K+] = 3.3 mmol/L [Cl -] ＝ 116 mmol/L Urine [Na+] = 9 mmol/L BUN = 40 mg/dL Arterial pH = 7.25 [HCO3 -] = 12 mmol/L PaCO2 = 28 mmHg
