Question 2

caused by hyperventilation, fever, drugs that cause tachypnea

PH > 7.45
HCO normal
CO2 < 35

Answer 2

respiratory alkalosis

Question 3

caused by DKA, hypoxia, acidic drug overdoses (ASA)

HCO < 22
CO2 normal

Answer 3

metabolic acidosis

Question 4

caused by diuresis, excessive vomiting, IV sodium bicarb

PH > 7.45
HCO > 26
CO2 normal

Answer 4

metabolic alkalosis

Question 5

40-50 yrs old, productive cough, hypoxemia/hypercarbia

blue bloater, cor pulmonale with signs such as hepatomegaly, kussmauls sign, polycythemia w increased risk for DVT, PE, MI

Answer 5

chronic bronchitis

Question 6

50-75 yrs old, dyspnea (early DOE, later at rest), normal O2 decreased CO2)

pink puffer, pursed lip breathing, accessory muscle use, increased diameter of chest, hyperesonance, speaking in short sentences

Answer 6

emphysema

Question 7

disease causes production of excess mucous which decreases gas exchange in lungs resulting in hypoxia (cyanosis) and r sided HR causes generalized edema

Answer 7

blue bloater

Question 8

can’t meet their oxygen needs if they have not decompensated (lack of cyanosis) and they use pursed lip breathing

Answer 8

pink puffer
