HESI Registered Nurse EXIT Practice Exam

What diagnosis is most appropriate for a COPD client who now has difficulty walking to the mailbox?

1. Activity intolerance caused by fatigue related to chronic tissue hypoxia

2. Impaired mobility related to chronic obstructive pulmonary disease

3. Self-care deficit caused by fatigue related to dyspnea

4. Ineffective airway clearance related to increased bronchial secretions

The correct answer is: Activity intolerance caused by fatigue related to chronic tissue hypoxia

The diagnosis of activity intolerance caused by fatigue related to chronic tissue hypoxia is the most appropriate because it highlights the client's decreased ability to engage in physical activities, such as walking to the mailbox, due to the systemic effects of COPD. Individuals with chronic obstructive pulmonary disease often experience chronic tissue hypoxia, which occurs when there is an insufficient oxygen supply to body tissues. This lack of adequate oxygen delivery can lead to feelings of fatigue and weakness, making even simple tasks like walking short distances more challenging. Recognizing the connection between activity intolerance and fatigue due to hypoxia is crucial for nursing care, as it guides the interventions necessary to help the client improve their activity level and overall quality of life. The focus is on managing symptoms, possibly through supplemental oxygen therapy, pulmonary rehabilitation, or energy conservation techniques. This understanding helps the healthcare provider to tailor a care plan that addresses the specific limitations the client is facing related to their COPD diagnosis.
