A client has developed atelectasis postoperatively. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: The correct answer is B: Increasing dyspnea. Atelectasis is a condition where the lung tissue collapses, leading to decreased oxygen exchange and resulting in symptoms like dyspnea (difficulty breathing). This occurs because the collapsed lung tissue reduces the surface area available for gas exchange, leading to decreased oxygen saturation and increased work of breathing.
Facial flushing (choice A) is not typically associated with atelectasis. Decreasing respiratory rate (choice C) may not be a reliable indicator as the body may compensate by increasing respiratory rate to maintain oxygenation. Friction rub (choice D) is more commonly associated with conditions like pleurisy or pneumonia, not atelectasis.
