Potential causes for respiratory alkalosis include
Correct Answer: D
Rationale: Respiratory alkalosis results from excessive CO2 loss, raising pH. Hyperventilation causes this, common in anxiety or hypoxia. Hypotension and hypertension affect circulation, not breathing rate. Hypoventilation causes acidosis. D aligns with acid-base physiology, making it correct.

Question 5 of 5
A 56-year-old alcoholic man consumes a six-pack of beer before going to bed. After being absorbed from his gut, blood carries the alcohol through the portal vein into the liver where it can be metabolized. Ethanol is metabolized in multiple steps by various enzymes, including alcohol dehydrogenase. Which of the following describes a characteristic of this enzyme?
Correct Answer: D
Rationale: Alcohol dehydrogenase (ADH) metabolizes ethanol to acetaldehyde and is inhibited by fomepizole , used in poisonings. It doesn't act on acetaldehyde or acetate . Disulfiram blocks aldehyde dehydrogenase. ADH's role initiates ethanol breakdown.
