Which of the following responses might mechanically ventilated patients on elevated levels of PEEP experience?
a. Atelectasis
b. Decreased hemoglobin
c. Decreased PaO2
d. Hypotension
Homework Answers
c When elevated PEEP levels is used in focal process,PEEP can paradoxically worsen the oxygenation by two mechanisms.First increasedPEEP cause overdistention of normal alveoli in regions not affected by the focal process.This cause an increase in capillary resistance in those regions,which redistributes bloodflow to other regions thereby worsening ventillation.Second PEEP increases intrathoracic pressure,particularly when used in focal processes.This decrease venous return and cardiac output with subsequent adverse effects on systemic blood pressure and tissue oxygen delivery.

One pathway that appears to relate elevated cholesterol levels to atherosclerosis involves the oxidation of LDL. Which of the following are consequences of this process? a. Though the mechanism by which this occurs is not completely understood, this oxidation includes the peroxidation of fatty acids, the hydroxylation of cholesterol, and the oxidation of amino acids. b. The presence of scavenger receptors on macrophages allows unlimited cholesterol uptake, leading to its conversion to foam cells. c. Oxidized LDL products induce an...

10. A 6-month old girl presents with the following symptoms: lactate acidosis (elevated serum levels of lactate), elevated levels of alanine in both her urine and blood, and muscle weakness (suggesting low levels of ATP). Doctors diagnose her problem as dihydrolipoamide dehydrogenase deficiency (present in two complexes!). They attempt to treat the girl with dietary supplements of riboflavin, thiamine, and niacin. a) Explain how this enzyme deficiency gives rise to lactate acidosis.
