Overnight home care jobs are those positions in which you assist people with special health care needs, typically somewhere between the hours of 11 pm and 7 am. The people who require your services during these hours may include elderly persons, people recovering from surgery, or patients with mobility issues. In the course of your duties you may be required to monitor diagnostic medical equipment, clean wounds, dispense medication, assist with bathing or toilet functions, and record any irregularities or emergencies for physicians to reference later. As you are not a licensed health care worker, your medical responsibilities are limited, and you summon professional help in the case of dire medical emergency.
