During the apprehension test, which signs are monitored to gauge instability?

• A. Pulse rate
• B. Blood pressure
• C. Facial expression and guarding
• D. Respiratory rate

Answer: (C)

The key idea here is that the apprehension test assesses how the patient perceives and reacts to potential joint instability. The best indicators are the patient’s facial expression and guarding. When a person anticipates dislocation, they often grimace, tense the shoulder, or move to protect the area. These protective or fearful responses directly reflect perceived instability in the joint being tested. Vital signs like pulse, blood pressure, or respiratory rate aren’t specific to joint instability in this context; they can change with pain or anxiety but don’t indicate the mechanical sense of instability the test is meant to reveal. So, facial expression and guarding best demonstrate instability during the test.
