PTA Critical Thinking 3

Question 1

A PTA wants the best evidence for treating shoulder impingement. Which source provides the HIGHEST level of evidence?

Accepted Answer

A systematic review of randomized controlled trials

Answer

Systematic reviews synthesize multiple RCTs and sit at the top of the evidence hierarchy for clinical decision-making.

Question 2

What does the 'sensitivity' of a clinical test BEST describe?

Accepted Answer

The ability to correctly identify patients who DO have the condition

Answer

Sensitivity measures the proportion of true positives correctly identified; a highly sensitive test rarely misses the condition.

Question 3

A clinical guideline recommends cervical manual therapy, but the PTA's patient has significant osteoporosis. The BEST approach is to:

Accepted Answer

Avoid the technique and discuss the contraindication with the supervising PT

Answer

Clinical guidelines apply to the general population; patient-specific contraindications must be identified and communicated to the supervising PT before proceeding.

Question 4

Which statement BEST defines evidence-based practice (EBP) in physical therapy?

Accepted Answer

Integrating best research evidence, clinical expertise, and patient values

Answer

EBP is a three-legged stool: research evidence, clinician expertise, and patient preferences must all be considered.

Question 5

A PTA reads a study concluding that ultrasound is ineffective for calcific tendinitis. The BEST response is to:

Accepted Answer

Discuss the finding with the supervising PT to inform clinical decision-making

Answer

New evidence should be brought to the supervising PT's attention; the PTA does not unilaterally change the plan of care based on a single study.
