The clinician is caring for Diane, a 22-year-old woman who presents with an injured ankle. Diane asks the clinician if she will need an x-ray.
The clinician explains to Diane that an x-ray is not always necessary for an injured ankle, and that the decision to obtain radiographs is dependent on the exam and Diane's description of her injury. Which of the following clues in Diane's exam or history would alert the clinician to the need for obtaining radiographs?
a. If she was not able to bear weight immediately after the injury
b. If the ankle developed marked swelling and discoloration after the injury
c. If crepitation occurs with palpation or movement of the ankle
d. All of the above
Question 2
The clinician suspects that a client has patellar instability. In order to test for this, the client is seated with the quadriceps relaxed, and the knee is placed in extension.
Next the patella is displaced laterally and the knee flexed to 30. If instability is present, this maneuver displaces the patella to an abnormal position on the lateral femoral condyle, and the client will perceive pain. Testing for patellar instability in this way is known as:
a. Apprehension sign.
b. Bulge sign.
c. Thumb sign.
d. None of the above
