Which technique is most reliable to confirm correct placement of a nasogastric tube prior to initiating tube feedings?

The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first. This is the proper way to use a walker for ambulation, as it provides stability and reduces stress on the affected joints.

Choice A is wrong because the client should not look down at his feet to prevent falling, but rather look ahead at where he is going. Looking down can cause neck strain and loss of balance.

Choice C is wrong because the client should not place her full weight on the walker with her arms while taking steps, as this can cause upper extremity fatigue and injury. The client should use the walker as a support, not a crutch.

Choice D is wrong because the client should not lean forward at a 60-degree angle while stepping into the walker, as this can cause back pain and poor posture. The client should stand upright and move the walker forward about one step’s length at a time.
