Primary emphysema is commonly linked to an inherited deficiency of the enzyme -antitrypsin. Deficiency increases likelihood of emphysema because proteolysis in lung tissues is not inhibited
8. Identify the greatest single risk factor for reactivation of tuberculosis.
22. Explain the reason why obese people are at greater risk for dehydration than lean people.

Explain why insulin is used to treat hyperkalemia (too much potassium in blood).
Insulin promotes cellular entry of potassium, insulin deficits are accompanied by hyperkalemia
22. Identify the populations (e.g., infants, normal adults, elderly, obese persons, thin women or men, teanagers, etc) who at higher risk for fluid imbalance and provide reasons.
Infants and growing children have much greater fluid turnover than adults because their higher metabolic rate increases fluid loss. Infants lose more fluid through the kidneys because immature kidneys are less able to conserve water than adult kidneys.
Total body water also is affected by gender and body size. Because fat cells contain little or no water and lean tissue has a high water content, people with a higher percentage of body fat have less body fluid. Women have proportionately more body fat and less body water than men. Water accounts for approximately 60% of an adult man’s weight, but only 52% for an adult woman. In an obese individual this may be even less, with water responsible for only 30% to 40% of the person’s weight.
People with an illness and those participating in strenuous activity are at risk for fluid and electrolyte imbalances when the environmental temperature is high. Fluid losses through sweating are increased in hot environments as the body attempts to dissipate heat. These losses are even greater in people who have not been acclimatized to the environment.
Explain why patients with metabolic acidosis breathe deeply and rapidly (Kussmaul respiration).
The respiratory system’s efforts to compensate for the increase in metabolic acids result to kussmaul respiration. This represents the body to compensate for the increase pH by blowing off carbon dioxide, which decreases carbonic acid.
