A client who had surgery for lung cancer has an established short- term goal of "Client will experience no impairment in breathing pattern for the next three postoperative days." Which finding indicates the goal has not been achieved?

Postoperative care following lung cancer surgery focuses on maintaining effective ventilation, airway clearance, and preventing complications such as atelectasis and pneumonia. An intact breathing pattern requires adequate respiratory effort, normal gas exchange, and the ability to clear secretions effectively. Retained secretions can obstruct airways, impair oxygenation, and increase infection risk. Evaluating respiratory function involves both clinical findings and diagnostic indicators such as breath sounds and arterial blood gases. Rationale: A. Inability to cough up respiratory secretions is concerning but does not definitively indicate that impairment has already occurred. It suggests a risk for ineffective airway clearance, which may lead to complications if not addressed. However, without evidence of retained secretions or impaired oxygenation, it reflects a potential problem rather than a confirmed failure of the goal. B. A consistent respiratory rate of 22 to 28 breaths per minute indicates mild tachypnea but may be expected in the immediate postoperative period due to pain, anxiety, or increased metabolic demand. It requires monitoring, but it does not alone confirm impaired breathing pattern if oxygenation and ventilation remain adequate. C. Pooling of thick secretions in the respiratory tract indicates ineffective airway clearance and directly impairs breathing. Accumulated secretions can obstruct airflow, reduce oxygen exchange, and increase the risk of infection. This finding clearly demonstrates that the client is not maintaining an effective breathing pattern, meaning the goal has not been achieved. D. Arterial blood gases within these values (pH 7.34, PaCO₂ 45 mmHg, HCO₃ 26 mEq/L) are near normal with only slight variation, suggesting adequate ventilation and acid-base balance. These findings do not indicate significant impairment in breathing pattern. They reflect relatively stable respiratory function rather than deterioration.
