Question

which of the following is not a reason a reflex response may fail during a clinical exam?
some reflexes disappear with age.
the person may consciously suppress the response.
the cns may be damaged.
there may be nerve conduction problems.
the nerves may be damaged.

Explanation:

Reflexes are involuntary responses. CNS damage, nerve conduction problems, and nerve damage can disrupt the reflex arc. Some reflexes do disappear with age. However, reflexes are involuntary, so a person cannot consciously suppress a true reflex response (as opposed to a voluntary muscle movement that might mimic a reflex - but the question is about reflex responses).

Answer:

The person may consciously suppress the response.
