The Call Button Is Within Reach at Breakfast and Gone by Supper. Catch the Drift Before You Leave the Room.

You set the call button beside her after breakfast. Later she moves to the recliner. The button stays on the bed. After lunch, someone places it on the table, just beyond her hand. By evening, the cord is behind the cushion.

The button still works. That is not the same as your wife being able to use it.

This failure starts quietly. You notice more calling from the other room. You find her trying to reach across an armrest. She says she pressed the button, but you heard nothing. You begin carrying the button from place to place yourself, without writing down where it belongs or checking whether she can reach it.

Put the reach check on the day sheet. Do not leave it as one more thing you are supposed to remember.

Start with the way she actually calls you

Write down what she uses when you are out of the room. It may be a call button, a wireless doorbell, a phone, a voice device, or a bell. If she has several choices, name the one she can use without sitting up, twisting, or reaching across furniture.

Watch her use it from each regular place. Ask her to call you from the bed, recliner, kitchen chair, and toilet if she spends time there alone. Do not place the device in her hand for the test. Let her find it, pick it up, and activate it.

Check what happens when her stronger hand is under a blanket, holding a cup, or resting on the far side. Check whether she can see the control and tell it apart from the television remote. If the device slips when she presses it, the location is not settled.

Give every place one landing spot

Choose one visible landing spot at each place she uses. The spot should not change depending on who helped her sit down.

At the bed, that might be a holder attached where she can reach it without rolling. At the recliner, it might be a pouch on the arm she uses. At the kitchen chair, it might be a marked place on the table within her normal reach.

A loose device on a blanket, tray, or cushion can move when she shifts. A cord can fall behind furniture or catch on a wheel. A phone can be set down with the screen facing away. Look at the whole setup, not just whether the device is somewhere nearby.

Keep television controls, tissues, drinks, and papers out of the landing spot. If everyone uses that space for something different, the call device will keep being moved.

Put the check after every move

The weak point is not breakfast or bedtime. It is the move between places.

Write each move on the left side of the day sheet. On the right, write the final check: call device in its landing spot, wife can reach it, test signal received.

At 6 a.m., after helping her out of bed, put the device at the chair and test it. After toileting, return it to the next landing spot before you wash your hands, gather laundry, or start breakfast. After a nap, move it with her, not on the next trip through the room.

If another person helps with the move, that person owns the reach check. A handoff is not finished when your wife is seated. It is finished when the caller is placed, reachable, and tested.

Learn the early signs that the setup is failing

Look for small changes before there is a long unanswered call.

The device is often found on the floor. Your wife starts shouting instead of using it. She reaches for the television remote when asked to call. The battery is charged, but the device is not beside her. An aide says, "I thought you had it." You hear the signal in one room but not where you cook, shower, or sleep.

One miss can be a placement mistake. Repeated misses mean the setup does not survive the day. Mark where and when each miss happened. The pattern may show one chair, one move, or one handoff that needs to change.

Test your end of the call

Your wife reaching the button is only half of the route. Test where the signal goes.

Stand in the places where you are likely to be when she calls. Close the bathroom door. Run the kitchen fan. Put the receiver where you normally carry or leave it. If the signal depends on a phone, check whether the phone is charged, audible, and with you.

Write down what you will do if the signal cannot be heard in part of the house. The answer may be moving the receiver, carrying it with you, or arranging another person to stay with her while you are beyond its range. Do not count shouting as the backup if her voice cannot reliably reach you.

Set a stop point

There may be times when your wife cannot find, hold, or activate the device even after you place it correctly. She may also stop remembering what it is for. That means the device can no longer cover time alone in the room.

Write the stop point plainly: if she cannot complete the call test, I do not leave until another person takes over or I change the task.

This matters before you shower, carry something downstairs, work outside, or sleep in another room. The device does not make those absences covered unless she can start the call and you can receive it.

Use one line at every handoff

When someone takes over, do not say only that the button is nearby. Show the landing spots and ask the person to run one test with your wife.

Put this on the handoff sheet: "After every move, place the caller in the marked spot, ask her to press it, and confirm that the signal arrived." Add the stop point beneath it.

At the end of the handoff, ask where the device failed, fell, or had to be moved. Put that note on the next day sheet. You are looking for the first repeated miss, not waiting for a night when she calls and nobody hears.

The line to write tonight

Before you go to bed, add one task beside every move on tomorrow's sheet: "Caller placed, reachable, and tested." Then name who owns that check.

If no one owns it, you do. If you cannot stay within range, that time needs a handoff. The useful question is not whether the button works. It is whether the whole call can travel from her hand to you every time you leave the room.
