SFCC Certified Nurse Assistant (CNA) Practice Test 2025 - Free CNA Practice Questions and Study Guide

The documentation "Amb. ad lib SOB this shift" indicates that Mr. Henderson is permitted to ambulate as desired, which is what "ad lib" signifies, meaning "as desired" or "as tolerated." The inclusion of "SOB," which stands for shortness of breath, suggests that while he can walk freely, he is experiencing difficulty in breathing during this activity. This documentation highlights that he is able to move about independently but is facing challenges, specifically related to his respiratory status. This information is crucial for caregivers and healthcare providers to monitor his condition closely and provide necessary support or interventions as needed.

The other answer choices do not capture the nuances of his current state as effectively. For instance, indicating that he is experiencing significant pain, restricted from ambulating, or fully independent in all activities would not accurately reflect the combination of mobility and breathing challenges noted in the documentation.
