A client states, “I can hear a crunching or grating sound when I kneel and have difficulty getting out of bed in the morning because of pain and stiffness.” Which of the following should the nurse expect as an assessment finding?
A.
Bone spur
B.
Crepitation
C.
Tendonitis
D.
Fluid in the knee joint
The correct answer and Explanation is :
The correct answer is B. Crepitation.
Crepitation refers to the crunching or grating sound heard in joints, often associated with conditions like osteoarthritis (OA). This symptom results from the degeneration of cartilage within the joint, causing bones to rub against each other. The client’s description of a “crunching or grating sound when kneeling” aligns with this phenomenon. Crepitus is commonly experienced in joints such as the knees, where cartilage degradation is prominent.
Explanation:
- Osteoarthritis (OA) is a degenerative joint disease characterized by the breakdown of cartilage, which cushions the ends of bones. As the cartilage wears away, the bones begin to make direct contact, leading to the crunching or grating sound (crepitus) that the client describes. This sound is usually more pronounced during movements like bending or kneeling.
- Morning stiffness and pain upon waking are hallmark symptoms of OA. Clients often report stiffness that lasts for a short period after waking up, typically less than 30 minutes, as they begin to move and loosen up their joints. The difficulty in getting out of bed is due to the reduced flexibility and range of motion in the affected joints, a result of cartilage degeneration and inflammation.
- Bone spur (A) refers to bony growths that can form along the edges of bones, particularly in joints affected by OA. While they can contribute to joint pain, they do not typically cause a crunching sound.
- Tendonitis (C) involves inflammation of tendons, often resulting from overuse or injury. It causes pain and limited movement but is less likely to produce a grating sound within the joint itself.
- Fluid in the knee joint (D), or joint effusion, can cause swelling and discomfort but is not typically associated with crepitation. Joint fluid buildup is more commonly associated with inflammatory conditions like rheumatoid arthritis or injury.
In conclusion, crepitation is a key finding in clients with symptoms of OA, helping distinguish it from other musculoskeletal conditions. Proper assessment, along with client history, can guide management strategies aimed at reducing pain, improving mobility, and preserving joint function.
