A student nurse is assisting a patient who is ambulating with a new walker. Which of the following is appropriate information for student nurse to provide to the patient?
a. "The top of the walker should line up with the crease on the inside of your elbows."
b. "You should walk behind the walker to maintain balance."
c. "You should lean forward over the walker to maintain balance."
d. "When walking, you should take a step, move the walker forward, and take anoth-er step."
D
When the person relaxes the arms at the side of their body, the top of the walker should line up with the crease on the inside of the wrist. A walker is fitted correctly by having the patient step inside the walker. The person's elbow should bend comfortably, about 30 degrees, while holding onto the grips. When walking, the patient holds the handgrips on the upper bars, takes a step, moves the walker forward, and takes another step. The patient should not lean over the walker or walk behind it; otherwise he or she might lose balance and fall.
