A Nurse Is Assessing A Client's Sensory Level And Determines That The Client Has Sensory Changes On The Top Of The Shoulder. Which Of The Following Dermatome Levels Is Associated With The Sensory Deficit?A. C-4 B. T-8 C. L-2 D. S-1
As a nurse, assessing a client's sensory level is a crucial aspect of their care. It helps identify potential issues with the nervous system and guides treatment decisions. In this article, we will explore the concept of dermatomes and how to determine the associated dermatome level in cases of sensory deficits.
What are Dermatomes?
Dermatomes are areas of skin that are supplied by nerves that arise from specific spinal nerve roots. Each dermatome corresponds to a specific spinal nerve root, and damage to these nerves can result in sensory deficits in the corresponding dermatome. Dermatomes are typically numbered from C-1 (cervical) to S-5 (sacral), with each number representing a specific spinal nerve root.
Understanding the Dermatome Map
To determine the associated dermatome level in cases of sensory deficits, it is essential to understand the dermatome map. The dermatome map is a diagram that shows the areas of skin supplied by each spinal nerve root. Here is a brief overview of the dermatome map:
- Cervical Dermatomes (C-1 to C-8): These dermatomes cover the skin on the neck, shoulders, and upper back.
- Thoracic Dermatomes (T-1 to T-12): These dermatomes cover the skin on the chest, abdomen, and lower back.
- Lumbar Dermatomes (L-1 to L-5): These dermatomes cover the skin on the lower back, hips, and legs.
- Sacral Dermatomes (S-1 to S-5): These dermatomes cover the skin on the buttocks, thighs, and feet.
Determining the Associated Dermatome Level
To determine the associated dermatome level in cases of sensory deficits, the nurse must assess the client's sensory level and identify the specific area of skin affected. In the case of the client with sensory changes on the top of the shoulder, the nurse must identify the corresponding dermatome level.
Answering the Question
Based on the dermatome map, the top of the shoulder is associated with the C-5 dermatome. Therefore, the correct answer is:
- A. C-4: This is incorrect, as the top of the shoulder is not associated with the C-4 dermatome.
- B. T-8: This is incorrect, as the top of the shoulder is not associated with the T-8 dermatome.
- C. L-2: This is incorrect, as the top of the shoulder is not associated with the L-2 dermatome.
- D. S-1: This is incorrect, as the top of the shoulder is not associated with the S-1 dermatome.
Conclusion
In conclusion, understanding dermatomes and the dermatome map is essential for nurses to assess and identify sensory deficits in clients. By knowing the corresponding dermatome level, nurses can provide accurate information to healthcare providers and guide treatment decisions.

Q: What is the dermatome map?
A: The dermatome map is a diagram that shows the areas of skin supplied by each spinal nerve root. It is a useful tool for nurses to identify the corresponding dermatome level in cases of sensory deficits.
Q: What are the different types of dermatomes?
A: There are four main types of dermatomes:
- Cervical Dermatomes (C-1 to C-8): These dermatomes cover the skin on the neck, shoulders, and upper back.
- Thoracic Dermatomes (T-1 to T-12): These dermatomes cover the skin on the chest, abdomen, and lower back.
- Lumbar Dermatomes (L-1 to L-5): These dermatomes cover the skin on the lower back, hips, and legs.
- Sacral Dermatomes (S-1 to S-5): These dermatomes cover the skin on the buttocks, thighs, and feet.
Q: How do I assess a client's sensory level?
A: To assess a client's sensory level, use the following steps:
- Identify the specific area of skin affected.
- Use the dermatome map to identify the corresponding dermatome level.
- Assess the client's sensory level by asking them to identify the sensation of touch, pressure, or temperature in the affected area.
- Document the client's sensory level and any changes in their sensation.
Q: What are the common causes of sensory deficits?
A: The common causes of sensory deficits include:
- Nerve damage: Damage to the nerves that supply the skin can result in sensory deficits.
- Spinal cord injuries: Injuries to the spinal cord can result in sensory deficits.
- Neurological disorders: Certain neurological disorders, such as multiple sclerosis, can result in sensory deficits.
- Infections: Infections, such as meningitis, can result in sensory deficits.
Q: How do I provide care for a client with sensory deficits?
A: To provide care for a client with sensory deficits, follow these steps:
- Assess the client's sensory level and identify the corresponding dermatome level.
