Cough Reflex Test (CRT) Practice Exam 2025 - Free CRT Practice Questions and Study Guide.

An abnormal result in a Cough Reflex Test indicates an impaired cough reflex, which raises concerns about the patient's ability to protect their airway. The cough reflex is a vital protective mechanism that prevents aspiration, which can occur when food, liquid, or other foreign materials enter the trachea and lungs. If this reflex is weak or absent, the patient is at a higher risk for aspiration pneumonia and other respiratory complications, such as airway obstruction or chronic lung infections.

In contrast, healthy respiratory function would typically be indicated by a normal cough reflex. The aging process alone may lead to some changes in lung function, but it does not specifically imply impairment of the cough reflex. Additionally, a strengthened immune response would not directly relate to the cough reflex test, as this test primarily assesses the mechanical and neurological aspects of the cough response rather than immune function.
