Example Questions

Example Question #113 : Injuries And Disorders

The fulcrum test and the patellar-pubic percussion test are tests for fractures of which bone?

Possible Answers:

Ilium

Ischium

Femur

Patella

Pubis

Correct answer:

Femur

Explanation:

These are tests for femur fractures, specifically for fractures of the femoral neck. The fulcrum test involves having the patient sit with his/her affected leg hanging off the edge of a surface, then the examiner will place his/her forearm under the shaft of the femur. If the patient experiences pain in the femur upon applying downward force on the knee, the result is positive, and the patient has fractured the femur. The patellar-pubic percussion test involves the use of a stethoscope on the lateral aspect of the pubic symphysis of the leg being examined. The patella is tapped with the tip of a finger or a tuning fork. Normally, there will be a distinct, loud sound that is caused by each tapping; if the sound is dissipated or muffled, this indicates a femoral fracture. 

Example Question #114 : Injuries And Disorders

A patient comes into the emergency room (ER), complaining of pain in his knee. You think the patient might have a fracture, and may need an x-ray, but you are uncertain. Which of the following findings would warrant an x-ray of the patient’s knee?

Possible Answers:

He is unable to take more than 4 steps with his injured leg

He is unable to flex his knee past 

The patient is younger than 55

He has tenderness at his tibial tuberosity

He has bruising around his patella

Correct answer:

He is unable to take more than 4 steps with his injured leg

Explanation:

Inability to take more than 4 steps with the injured leg is one of the criteria of the is used order x-rays for suspected fractures around the knee complex, per the Ottawa knee rules. The other criteria are as follows: isolated tenderness at the patella or tenderness at the fibular head or patient age greater than 55 or inability to flex the knee past .

Example Question #115 : Injuries And Disorders

The closed fist percussion sign would be useful for diagnosing which pathology?

Possible Answers:

Acetabular labrum tear

Glenoid labrum tear

Femoral neck fracture

Vertebral compression fracture

Correct answer:

Vertebral compression fracture

Explanation:

Although diagnostic imaging is needed to conclusively to rule in a fracture, the closed fist percussion sign has good diagnostic value in detecting vertebral compression fractures. Given that this tests involves hitting a patient in the back, clinicians may be hesitant to use this test. In such cases, the supine sign (increased pain with lying supine) can also be used to screen for vertebral compression fractures.

Example Question #116 : Injuries And Disorders

Which of the following diagnostic criteria is not used to screen for fractures?

Possible Answers:

Ottawa ankle rules

Well's criteria

Ottawa knee rules

Amsterdam wrist rules

Correct answer:

Well's criteria

Explanation:

As their names suggest, the Ottawa knee and ankle rules, and the Amsterdam wrist rules are used to determine which patients should receive x-rays for suspected ankle, knee, and wrist fractures respectively. Well's criteria are used to screen for pulmonary embolisms (PEs) and deep vein thromboses (DVTs). It should be noted that there are distinct Well's criteria for PEs and DVTs.
