A nurse is assessing a client who is experiencing amphetamine withdrawal. Which of the following findings should the nurse expect?

Introduction: Amphetamine withdrawal, often referred to as a crash, is characterized by a depressive rebound effect as the central nervous system attempts to compensate for the depletion of dopamine and norepinephrine stores. A. Increased concentration is not expected; instead, withdrawal is characterized by cognitive slowing and significant difficulty with focus. The brain, accustomed to high levels of chemical stimulation, enters a state of hypometabolism during withdrawal, making even simple tasks feel mentally exhausting and difficult to complete. B. Euphoria is a symptom of intoxication, not withdrawal. During withdrawal, the client typically experiences profound dysphoria, irritability, and anhedonia (the inability to feel pleasure). This emotional "low" is the result of the brain's reward system being severely downregulated after chronic or high-dose stimulant exposure. C. Decreased appetite is associated with stimulant use (intoxication). In withdrawal, the body experiences a rebound effect, leading to an intense increase in appetite, often called "hyperphagia." The client may consume large quantities of food as the stimulant-induced appetite suppression wears off and energy stores are replenished. D. Fatigue is a cardinal sign of amphetamine withdrawal. Following the period of hyper-arousal and sleeplessness associated with stimulant use, the client experiences extreme lethargy and "crashing," which often involves sleeping for extended periods as the nervous system attempts to recover from the hyper-stimulated state.
