A client presents to the emergency department with acute abdominal pain and a provisional diagnosis of pancreatitis. The client reports nausea and vomiting from laboratory studies. Which information is most valuable in reporting the client’s status to the healthcare provider?

Choice A reason: Monitoring oxygen saturation is critical in COPD, as oxygen therapy aims to maintain saturation (88–92%) to prevent hypoxia. Pulse oximetry ensures adequate oxygenation, guiding therapy adjustments, making it the priority assessment to prevent respiratory failure and optimize lung function.

Choice B reason: Checking skin color assesses cyanosis but is less precise than oxygen saturation. Pulse oximetry provides objective data on oxygenation in COPD, guiding oxygen therapy, making it the priority over subjective visual assessments, which are secondary to quantitative measures.

Choice C reason: Assessing chest pain is relevant for cardiac issues but not the primary concern in COPD oxygen therapy. Oxygen saturation directly evaluates therapy effectiveness, preventing hypoxia, making it the priority assessment to ensure respiratory stability in chronic lung disease.

Choice D reason: Measuring blood pressure monitors cardiovascular status but is secondary to oxygenation in COPD. Oxygen saturation is critical, as hypoxia exacerbates respiratory distress, requiring immediate assessment to adjust oxygen therapy, making it the priority over hemodynamic evaluations.

Choice A reason: Obtaining an arterial blood gas assesses oxygenation and acid-base status, useful in COPD management, but is not required before postural drainage. This invasive procedure is unnecessary for routine drainage, which mobilizes secretions. Explaining positions prepares the client, enhancing cooperation and effectiveness.

Choice B reason: Performing drainage after meals risks aspiration or vomiting, as a full stomach increases intra-abdominal pressure in COPD patients. Postural drainage is most effective when performed on an empty stomach, making this approach incorrect. Patient education on positioning is the priority.

Choice C reason: Shallow, fast breathing is counterproductive in COPD, as it reduces tidal volume and worsens hypercapnia. Postural drainage requires slow, deep breaths to mobilize secretions and improve ventilation. Explaining positions ensures proper technique, making this breathing instruction incorrect.

Choice D reason: Explaining that the client may be placed in five positions (e.g., prone, supine, lateral) prepares them for postural drainage, which uses gravity to mobilize lung secretions in COPD. This education enhances compliance and effectiveness, as proper positioning is critical for therapeutic success, making it the correct approach.
