What is the observation by the nurse suggests that the client tolerated the activity without distress?

The client's pulse and respiratory rates increased moderately during ambulation.

Pulse and respiratory rates normally increase during and for a short time after ambulation, especially if its the first ambulation after 3 days of bed rest. Anormal walking pace is 70 to 100 steps/minute; a much slower pace may indicate distress. dizziness, weakness, and profuse perspiration are definite signs of activity intolerance. Aclient who tolerates ambulation well holds his head erect, gazes straight ahead, and keeps his toes pointed forward. Aclient who ambulates with his head down, gaze cast down, and toes pointed outward is exhibiting activity intolerance.
