NATA-BOC Clinical Evaluation and Diagnosis Questions and Answers 1

Question 1

An athlete lands awkwardly from a jump and reports an audible 'pop' in the knee, followed by immediate effusion and a feeling of instability. During the on-field examination, the athletic trainer performs a Lachman's test, which reveals excessive anterior tibial translation with a soft end-feel. Which injury is most likely present?

Accepted Answer

Anterior Cruciate Ligament (ACL) Tear

Answer

The mechanism of injury (awkward landing), audible 'pop', significant effusion, and feeling of instability are classic signs of an ACL tear. A positive Lachman's test, especially with a soft end-feel, is considered the most accurate clinical test for diagnosing an ACL rupture.

Question 2

Which of the following represents the subjective portion of a standard SOAP note?

Accepted Answer

The athlete's description of the mechanism of injury and pain level.

Answer

The 'S' in SOAP stands for Subjective. This section includes all information reported by the athlete, such as their chief complaint, mechanism of injury, pain description, and feelings about the condition. The other options belong in the Objective (B), Assessment (C), and Plan (D) sections.

Question 3

A soccer player presents with a gradual onset of anterior knee pain that is worse when running downhill and after prolonged sitting. Palpation reveals point tenderness over the inferior pole of the patella, and resisted knee extension is painful. Which condition is most consistent with these findings?

Accepted Answer

Patellar Tendinopathy

Answer

This presentation is classic for patellar tendinopathy (Jumper's Knee). Key features include localized pain at the inferior pole of the patella, aggravation with eccentric loading (running downhill), and pain with resisted knee extension. PFPS pain is typically more diffuse around the patella, IT band syndrome is lateral, and Osgood-Schlatter disease involves the tibial tuberosity.

Question 4

During a neurological screening of the upper extremity, an athletic trainer finds weakness during resisted shoulder abduction and diminished sensation over the deltoid patch area. Which nerve root is most likely implicated?

Accepted Answer

C5

Answer

The C5 nerve root provides motor innervation to the deltoid muscle (shoulder abduction) and sensory innervation to the lateral aspect of the upper arm, known as the deltoid patch area. Therefore, weakness and sensory loss in this specific pattern strongly suggest C5 nerve root involvement.

Question 5

Which of the following best describes the normal physiological end-feel an athletic trainer should expect when performing passive wrist flexion on a healthy individual?

Accepted Answer

Firm

Answer

A firm end-feel is expected during passive wrist flexion due to the tension created by the stretching of the posterior radiocarpal ligament, dorsal joint capsule, and wrist extensor muscles. A soft end-feel is due to soft tissue approximation (e.g., knee flexion), a bone-to-bone end-feel is hard (e.g., elbow extension), and an empty end-feel is when the patient stops the movement due to pain.
