  1. ATo alert staff when the resident attempts to get up unsupervised
  2. BTo monitor the resident's vital signs continuously
  3. CTo restrain the resident's movement during the night
  4. DTo physically prevent the resident from getting out of bed
Show answer & explanation

Correct answer: A. To alert staff when the resident attempts to get up unsupervised

A bed alarm is designed to alert staff when a resident who is at risk for falls attempts to get up without assistance, allowing timely intervention. It does not physically restrain the resident and is not a monitoring device for vital signs.

Why the other options are wrong

  • B. Incorrect; bed alarms do not monitor vital signs; they detect movement or weight shifts.
  • C. Incorrect; bed alarms are not restraints and should not be used as such.
  • D. Incorrect; a bed alarm does not physically stop movement, it only alerts staff.

Bed Alarm Purpose

A bed alarm alerts staff when an at-risk resident attempts to get out of bed unsupervised, enabling timely intervention to prevent falls.

  • Not a physical restraint
  • Detects movement or weight shift
  • Allows staff to respond before a fall occurs

Memory trick: The alarm doesn't hold them down, it just rings the alarm sound.
