A nurse is reinforcing teaching with a client who is dependent on nicotine and wishes to discontinue smoking. The nurse should inform the client that which of the following is a manifestation of nicotine withdrawal?

A) Weight loss: Weight loss is not a typical manifestation of nicotine withdrawal. While some individuals may experience changes in appetite, particularly an increase in appetite leading to weight gain, weight loss is not a common symptom associated with quitting smoking. B) Diaphoresis: Diaphoresis, or excessive sweating, is not typically associated with nicotine withdrawal. While some individuals may experience mild symptoms like irritability or nervousness, sweating is not a prominent feature of withdrawal from nicotine. C) Diarrhea: Diarrhea is not a characteristic symptom of nicotine withdrawal. Some gastrointestinal disturbances such as constipation or changes in appetite may occur, but diarrhea is not a common withdrawal symptom. D) Insomnia: Insomnia is a well-documented symptom of nicotine withdrawal. Nicotine has stimulating properties, and when an individual stops using nicotine, they may experience difficulty sleeping. This can lead to trouble falling or staying asleep and is a common part of the withdrawal process.
