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?

Choice A reason: Weight gain, not loss, follows nicotine cessation due to appetite increase. Withdrawal heightens metabolism briefly, but loss isn’t a typical manifestation.Choice B reason: Diaphoresis occurs during acute withdrawal but isn’t primary. Nicotine’s absence disrupts sleep more consistently, making this a less dominant symptom.Choice C reason: Insomnia is a hallmark of nicotine withdrawal, from CNS stimulation loss. It disrupts sleep regulation, a common, persistent issue in quitting smokers.Choice D reason: Diarrhea can occur but is less frequent than insomnia in withdrawal. Nicotine’s absence more reliably affects sleep over GI motility initially.
