91
Q

93
Q

what are the results of a normal weber test?

A

No lateralization of sound at all

94
Q

results of weber test with unilateral conductive loss

A

Lateralizes to affected ear

Q

Palliative Care vs. Hospice

A
  • Hospice, as defined by the Medicare hospice benefit, is a health care delivery system under which support and services are provided to a patient with a terminal illness where the focus is on comfort rather than curing an illness.
  • Thus, hospice can be considered a program that delivers palliative care to patients at the end of life, while palliative care can be appropriately offered to patients at any time along the trajectory of any type of serious illness, even concurrent with restorative, life-prolonging therapies.
  • Hospice is a model of palliative care that is offered to patients at the end of life when curative or life-prolonging therapy is no longer indicated.
  • While all care that is delivered by hospices can be considered palliative care, not all palliative care is delivered in hospices.
