Question

7. A 75 year old male with hypertension, hyperlipidemia, and stage III congestive heart failure secondary to ischemic cardiomyopathy presents for a routine appointment. He takes 40 mg of furosemide twice daily. His HCO on basic metabolic panel is 36 so an ABG is performed. The ABG is pH 7.44/pCO2 49/HCO 37/anion gap 10 Disorder: Cause 8. A 35 year female physician with a history of asthma and severe allergies to pollen develops urticarial (hives), hypotension and stridor when she puts on a pair of latex gloves. In the Emergency Department her ABG is pH 7.21/ pCO2 64/HCO 23/ anion gap 10 Disorder Cause: 9. 25 year old woman who is 6 months pregnant presents with a 3 day history of vomiting from viral gastroenteritis. The ABG in the Emergency Department is pH 7.6/ PCO2 44 HCOy 28/anion gap 12 Disorder Cause

Answer 1

7. Disorder is Metabolic alkalosis .

Cause for metabolic alkalosis is use of furosemide . Excessive use of furosemide will most likely lead to a metabolic alkalosis due to hypochloremia and hypokalemia

8. Disorder is Respiratory acidosis

Cause for respiratory acidosis is allergic reaction to latex gloves .Latex allergy symptoms may include hives, itching, stuffy or runny nose. It can cause asthma symptoms of wheezing, chest tightness and difficulty breathing. Symptoms begin within minutes after exposure to latex containing products.

9. Disorder is Metabolic alkalosis .

Cause of metabolic alkalosis is prolonged vomiting induced by viral gastroenteritis . Vomiting causes lose of gastric secretions which is rich in hydrochloric acid and hence leads to metabolic alkalosis .
