Cody is going to document in Mr. Brown's medical record.
Which of the following is appropriate to document? (Case #1)

Choice A rationale

Impaired gas exchange directly affects the patient's oxygenation and carbon dioxide elimination, which are fundamental physiological needs. Alveolar inflammation and infection in pneumonia disrupt the normal diffusion of gases in the lungs, potentially leading to hypoxemia and hypercapnia, posing an immediate threat to life if not addressed promptly. Normal partial pressure of oxygen (PaO₂) is 80-100 mmHg, and normal partial pressure of carbon dioxide (PaCO₂) is 35-45 mmHg.

Choice B rationale

Pruritus, or itching, while uncomfortable, is a symptom related to medication side effects and does not directly compromise vital physiological functions like gas exchange. Addressing the underlying cause and providing symptomatic relief are important but are a lower priority than ensuring adequate oxygenation.

Choice C rationale

Knowledge deficit regarding risk factors for pneumonia is important for long-term health management and prevention of future episodes. However, in the acute phase of pneumonia, the immediate physiological compromise of impaired gas exchange takes precedence over addressing knowledge gaps.

Choice D rationale

Activity intolerance due to fatigue and shortness of breath is a consequence of the physiological changes associated with pneumonia, primarily the impaired gas exchange. While it affects the patient's quality of life, it is a manifestation of the primary problem rather than the most immediate threat to physiological stability.

Developing a care plan is a collaborative process that ideally involves the physician, the patient, the nurse, and other members of the healthcare team. The physician's input is vital for medical diagnoses, treatment orders, and overall medical management, which are integral components of the patient's comprehensive care plan.
