Final answer:
A medical diagnosis, such as pneumonia, identifies the disease causing a patient's symptoms, whereas a problem statement, like 'altered gas exchange,' describes the patient's response to health issues and directs nursing interventions. Abnormal physical findings like hypoxemia and crackling lung sounds support the medical diagnosis, while the problem statement addresses specific nursing care.
Step-by-step explanation:
The difference between a medical diagnosis and a problem statement is primarily in their scope and function. A medical diagnosis, such as pneumonia, is determined by a healthcare provider based on an assessment of symptoms, physical examination findings, and diagnostic tests. It specifies the disease or condition that is causing the symptoms experienced by the patient. On the other hand, a problem statement, also known as a nursing diagnosis, like 'altered gas exchange r/t excessive lung secretions AEB crackles in both lungs,' provides a focused description of a patient's response to health issues that nurses are licensed to treat. It is used in nursing to direct interventions and achieve outcomes for which the nurse is accountable.
In the context of pneumonia, abnormal physical exam findings such as elevated heart rate, hypoxemia, crackling sounds upon auscultation, greenish mucus sputum, and a chest radiograph showing a shadow are indicative of the condition. These findings support the medical diagnosis of pneumonia, which requires treatment such as antibiotics or other therapies depending on whether the pneumonia is viral, bacterial, or otherwise caused.
The problem statement, detailing the specific nursing-sensitive issue of altered gas exchange, guides the nursing interventions to help alleviate symptoms like difficulty breathing and ensuring the patient gets enough oxygen. It reflects the nurse's role in patient care which complements the medical treatment plan for pneumonia
