Which of the following is covered under Medicare Part A?

Medicare Part A primarily focuses on providing coverage for inpatient care. This includes hospital stays, hospice care, and skilled nursing facility care after an inpatient hospital stay of at least three days. Skilled nursing facility care is characterized by the need for skilled rehabilitation services, such as physical therapy or nursing care that must be monitored by a healthcare professional.

In contrast, other options pertain to different aspects of Medicare coverage. Outpatient care usually falls under Medicare Part B, which covers services provided outside of hospitals, such as physician services and outpatient therapy. Durable medical equipment, like wheelchairs and CPAP machines, is also covered under Medicare Part B, not Part A. Preventative services, which include screenings and preventive exams, are generally part of Medicare Part B as well, emphasizing outpatient protective care rather than inpatient services. Hence, skilled nursing facility care is the correct answer as it is explicitly covered under Medicare Part A, reflecting its focus on facilitating necessary inpatient rehabilitation after hospitalization.
