Which statement made by a patient indicates an understanding about treatment of streptococcal pharyngitis?

A. Drive to breathe may be dependent on low levels of oxygen in the blood: Clients with emphysema may have chronically elevated CO₂ levels, which can blunt their central chemoreceptor response. As a result, their respiratory drive may rely more on peripheral chemoreceptors sensing low oxygen levels.

B. Respiratory rate may be increased a great part of the time: While some clients with emphysema may exhibit tachypnea during exertion or exacerbations, this is not a consistent or defining characteristic across all situations.

C. Lung stretch receptors may fail to monitor the patterns of breathing: Lung stretch receptors play a role in the Hering-Breuer reflex, but there is no evidence that they fail to function in emphysema. The issue in emphysema is gas trapping and reduced surface area for gas exchange, not receptor failure.

D. Intercostal muscles contract during inspiration, but fail to relax during expiration: The intercostal muscles assist with ventilation, particularly during increased respiratory effort. However, their relaxation in expiration is typically passive and not impaired in emphysema.

A. Physical therapy for homebound therapy services:Physical therapy is not routinely indicated in TB management unless the patient has specific mobility deficits. TB treatment focuses more on medication adherence and infection control rather than physical rehabilitation.

B. Occupational therapy for job retraining:There is no direct indication for job retraining in a TB patient unless the illness has caused long-term disability or affected occupational function, which is not suggested in this scenario.

C. Community social worker for Meals on Wheels:Meals on Wheels may assist with nutrition, but it is not specific to TB care. Social services do not directly ensure adherence to TB therapy, which is crucial for treatment success and public health safety.

D. Visiting Nurses for directly observed therapy:Directly observed therapy (DOT) ensures the client takes prescribed TB medications under supervision, which is essential to prevent noncompliance, reduce drug resistance, and promote cure. Visiting nurses are best positioned to provide this support during long-term outpatient TB treatment.
