Certified Wound Ostomy Nurse (CWON) Practice Test

What is the primary reason for testing vibratory sensation?

1. To assess overall motor function

2. To determine sensitivity to touch

3. To identify potential loss of protective sensation

4. To evaluate pain response

The correct answer is: To identify potential loss of protective sensation

Testing vibratory sensation is primarily important for identifying potential loss of protective sensation. This is particularly relevant in situations such as diabetes or peripheral neuropathy, where patients may experience reduced awareness of injury or pressure due to nerve damage. Assessing vibratory sensation allows healthcare professionals to detect these deficits early, helping in the prevention of injuries that could lead to complications such as ulcers or infections. Other options, while they may seem relevant, do not specifically address the core objective of vibratory sensation testing. Evaluating overall motor function, sensitivity to touch, or pain response involves different sensory modalities or functions that are not directly linked to the assessment of protective sensation. Understanding vibratory sensation focuses specifically on the integrity of the sensory pathways that protect against injury and demonstrates the importance of maintaining nerve function in high-risk populations.
