A nurse is reinforcing teaching with a client about naltrexone. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Serum creatinine levels are commonly used to assess kidney function. While kidney function is important, it does not specifically evaluate nutritional status. Chronic alcohol use can impact multiple organs, but thiamine deficiency is a more direct concern related to nutritional status in these patients.

Choice B reason: Thiamine (vitamin B1) deficiency is a well-known complication of chronic alcohol use disorder. Alcohol interferes with the absorption and utilization of thiamine, leading to deficiencies that can cause severe neurological problems, such as Wernicke's encephalopathy and Korsakoff's syndrome. Monitoring thiamine levels is crucial in assessing and managing the nutritional status of clients with chronic alcohol use disorder.

Choice C reason: Urinalysis is a basic test that can provide information about kidney function and the presence of infections, among other things. However, it is not specifically useful in evaluating the nutritional status of a client with chronic alcohol use disorder. Nutritional deficiencies would not be directly assessed through a routine urinalysis.

Choice D reason: Erythrocyte sedimentation rate (ESR) is a non-specific marker of inflammation and is used to detect inflammatory conditions. While it can provide information on inflammatory processes, it does not directly assess nutritional status. The nutritional impact of chronic alcohol use disorder is more accurately evaluated by specific nutrient levels, such as thiamine.

Choice A reason: Weight gain is a common manifestation after cessation of nicotine use. Nicotine is an appetite suppressant, and its absence can lead to increased appetite and caloric intake. Additionally, some individuals may turn to food as a substitute for smoking, leading to weight gain. Understanding this can help in planning strategies to manage weight during the cessation process.

Choice B reason: Difficulty concentrating is another common symptom experienced during nicotine withdrawal. Nicotine has stimulant effects on the brain, enhancing concentration and alertness. When a person stops using nicotine, they may experience cognitive difficulties, including trouble focusing and memory issues. These symptoms are typically temporary but can be challenging during the withdrawal period.

Choice C reason: Diarrhea is not a common manifestation of nicotine cessation. Gastrointestinal symptoms like constipation are more frequently reported during nicotine withdrawal. The body's digestive system adjusts to the absence of nicotine, which can result in changes in bowel habits, but diarrhea is less typical.

Choice D reason: Restlessness is a well-documented symptom of nicotine withdrawal. The body and mind are accustomed to the stimulant effects of nicotine, and its absence can lead to increased agitation and restlessness. This symptom can contribute to the difficulty of quitting smoking, as it creates a sense of discomfort and unease.

Choice E reason: Decreased appetite is not typically associated with nicotine cessation. Instead, increased appetite is more commonly observed due to the removal of nicotine's appetite-suppressing effects. Therefore, decreased appetite is not a typical manifestation of nicotine withdrawal.
