After falling down the basement steps, a client is brought to the emergency room. X-rays confirms that the client’s right leg is fractured. Following application of a leg cast, which assessment finding warrants immediate intervention by the nurse?
A.
Increased temperature to lower extremity.
B.
Right foot pale with sluggish capillary refill.
C.
Circumferential edema of right foot.
D.
Complaint of throbbing right leg pain
The Correct Answer and Explanation is:
The correct answer is B. Right foot pale with sluggish capillary refill.
Explanation:
After a fracture and the application of a leg cast, monitoring for complications is crucial. One of the most serious complications that can arise is compartment syndrome, which is an emergency situation that occurs when increased pressure within a muscle compartment reduces blood flow to the area. This can lead to permanent muscle and nerve damage if not treated promptly.
Assessment Findings and Their Implications:
- Increased Temperature to Lower Extremity (Option A):
- While increased temperature can indicate inflammation or infection, it is not an immediate indicator of severe complications such as compartment syndrome. Temperature changes can occur due to normal post-cast application or minor inflammation.
- Right Foot Pale with Sluggish Capillary Refill (Option B):
- This finding is most concerning. Pallor and sluggish capillary refill (greater than 2 seconds) suggest that the blood flow to the extremity is compromised. These signs are indicative of potential compartment syndrome, which can occur when swelling or bleeding within a muscle compartment increases pressure and impairs circulation. This condition requires urgent intervention to relieve pressure and restore blood flow to prevent irreversible damage.
- Circumferential Edema of Right Foot (Option C):
- Circumferential edema can be a normal response after casting and does not necessarily indicate an immediate need for intervention unless it leads to severe symptoms. However, it should be monitored closely as it could be a sign of worsening compartment syndrome.
- Complaint of Throbbing Right Leg Pain (Option D):
- Throbbing pain is common after a fracture and cast application due to inflammation and the normal healing process. While pain management is important, throbbing pain alone does not necessitate immediate intervention unless it is accompanied by other signs of compartment syndrome.
Immediate Action: The pale color and sluggish capillary refill in the right foot suggest compromised blood flow, which is a hallmark of compartment syndrome. Immediate intervention is required to relieve the pressure, such as loosening or removing the cast and addressing any underlying causes of increased pressure. Failure to address this can result in muscle necrosis, nerve damage, and loss of limb function. Therefore, this finding warrants prompt assessment and action by the nurse.
