Which of the following factors is NOT associated with a higher risk of post-surgical complications in obese patients?

A. This helps prevent air leaks and maintains the closed drainage system's function.
B. Looping the tubing on the client's is incorrect as it can lead to inaccurate drainage and measurement of the fluid.
C. Placing the drainage system above the level of the client's heart is incorrect as it can lead to inaccurate drainage and measurement of the fluid.
D. Routine stripping of the chest tube is also not recommended as it can cause trauma to the pleura and potentially lead to complications.

A. pH: Elevated (above 7.45), indicating alkalosis. PaCO₂: Decreased (below 35 mm Hg), reflecting hyperventilation and CO₂ loss. HCO₃⁻: Usually normal (around 24 mEq/L) or slightly decreased, as metabolic compensation might not be immediate. The results here show an elevated pH, decreased PaCO₂, and normal HCO₃⁻, which are consistent with respiratory alkalosis.
B. pH: Decreased (acidic), indicating acidosis. PaCO₂: Slightly elevated (near normal), not indicative of respiratory alkalosis. HCO₃⁻: Normal (around 26 mEq/L), suggesting no significant metabolic component or compensation. This profile does not match respiratory alkalosis; it is more consistent with a mixed or different type of acid-base imbalance.
C. pH: Decreased (acidic), indicating acidosis. PaCO₂: Elevated (above 45 mm Hg), indicating CO₂ retention, which is characteristic of respiratory acidosis, not alkalosis. HCO₃⁻: Normal (around 23 mEq/L), showing no significant metabolic compensation or disturbance. This profile indicates respiratory acidosis rather than respiratory alkalosis.
D. pH: Elevated (alkaline), which is consistent with alkalosis. PaCO₂: Normal (around 40 mm Hg), indicating that CO₂ levels are not the primary cause of the alkalosis. HCO₃⁻: Elevated (above 28 mEq/L), suggesting a metabolic alkalosis or compensation for a respiratory acidosis, but not respiratory alkalosis alone.
