The correct answer is: A. Inpatient.
An inpatient is a patient who is admitted to a hospital for treatment and stays overnight. Outpatients are patients who receive treatment at a hospital but do not stay overnight. Day patients are patients who receive treatment at a hospital during the day but go home at night. House patients are patients who live in a hospital but do not receive treatment.
Inpatients are typically admitted to a hospital for a more serious condition that requires overnight observation or treatment. They may also be admitted for surgery or other procedures that cannot be performed on an outpatient basis. Outpatients, on the other hand, typically receive treatment for less serious conditions that can be managed on an outpatient basis. They may come to the hospital for a doctor’s appointment, to have tests done, or to receive treatment such as medication or physical therapy. Day patients are similar to inpatients in that they receive treatment at a hospital, but they go home at night. This type of care is often used for patients who need more intensive treatment than can be provided on an outpatient basis, but who do not need to be hospitalized overnight. House patients are patients who live in a hospital but do not receive treatment. They may be there for long-term care or rehabilitation.
