A patient receiving long-term positive-pressure ventilation support exhibits a progressive weight gain and a reduction in the hematocrit. Which of the following is the most likely cause of this problem?

Question

Quizplus · Accepted Answer

Positive-pressure ventilation can lead to fluid retention and weight gain, which can lead to a reduction in hematocrit. This is due to increased venous return, increased hydrostatic pressure, and decreased lymphatic drainage, which can result in fluid accumulation in the interstitial spaces. This fluid retention can also lead to electrolyte imbalances such as hyponatremia. Pulmonary hemorrhage and hypovolemia would not likely result in weight gain, and hyponatremia is only one possible consequence of fluid retention.
