Final answer:
Assist Mr. Blevin with shirt removal by starting with his right arm which is unaffected by the stroke, providing comfort, and utilizing remaining muscular control in the right arm.
Step-by-step explanation:
When helping Mr. Blevin, who had a stroke causing muscle control loss in his left arm, to remove his shirt for bed, the proper technique would be to assist removing the shirt starting from the unaffected arm, in this case, the right arm. This is done to provide the maximum comfort and support to the affected limb. Since Mr. Blevin has motor control issues on his left side, beginning with the right arm allows him to use the remaining muscle tone and control in his right arm to aid in the removal of the shirt, while the caregiver supports the left arm throughout the process.
