A 4-year-old boy has been admitted to the hospital with pneumonia.He has been in the hospital for 3 days and has suddenly started to become incontinent of urine.The nurse knows that this is most likely a result of what ego-defense mechanism?

A) Compensation
B) Conversion
C) Denial
D) Regression

Regression is coping with a stressor through actions and behaviors associated with an earlier developmental period.Compensation is making up for a deficiency in one aspect of self-image by strongly emphasizing a feature considered an asset.Conversion is unconsciously repressing an anxiety-producing emotional conflict and transforming it into nonorganic symptoms (e.g.,difficulty sleeping,loss of appetite).Denial is avoiding emotional conflicts by refusing to consciously acknowledge anything that causes intolerable emotional pain.
