A body fluid found in joints is called?

Appeared in: DSSSB - 29 August 2019 (Shift-1)

Explanation

Synovial fluid is the specific type of fluid located within the cavities of synovial joints.
Its main functions are to lubricate the joint, reduce friction between the articular cartilage, absorb shock, and nourish the cartilage cells.
It is secreted by the synovial membrane, which lines the inside of the joint capsule.

Option A: Amniotic fluid is found in the amniotic sac surrounding a fetus during pregnancy, not in the joints.
Option B: Peritoneal fluid is located in the abdominal cavity, where it lubricates the organs. It is not found in joints.
Option D: Cerebrospinal fluid (CSF) circulates around the brain and spinal cord, providing cushioning and protection for the central nervous system, not the joints.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of body fluids and their specific locations in the human body as background academic context rather than a clinical decision trigger.
A key nursing and medical procedure related to synovial fluid is arthrocentesis, or joint aspiration. This involves using a needle to withdraw fluid from a joint cavity for analysis.
Nurses are responsible for preparing the patient, assisting with the sterile procedure, properly handling the collected specimen, and monitoring the patient for complications like bleeding or infection post-procedure.
The appearance of the aspirated fluid provides immediate clues: clear fluid is normal, cloudy or purulent fluid suggests infection (septic arthritis), and bloody fluid indicates trauma or a bleeding disorder.

How to Approach the Question

This is a factual recall question that tests your knowledge of basic anatomy and physiology.
First, identify the key term in the question: 'joints'.
Next, review the options provided, which are all different types of body fluids.
Recall or deduce the primary location of each fluid. 'Amniotic' relates to the amnion (pregnancy), 'peritoneal' to the peritoneum (abdomen), 'cerebrospinal' to the cerebrum and spine (brain/spinal cord), and 'synovial' to synovial joints.
Match the key term 'joints' with the corresponding fluid, which is 'synovial fluid'.
