A nurse in a mental health facility is reviewing the laboratory results of a client who is taking lithium carbonate.
Which of the following findings places the client at risk for lithium toxicity?

Choice A rationale:

A client with a history of dependent personality disorder does not necessarily require close placement to the nurse's station for safety reasons. The primary concern in this case is not related to Alzheimer's or potential wandering, so placing this client closer to the nurse's station is not warranted.

Choice B Reason: A client who has moderate-stage Alzheimer’s disease.This client should be placed closest to the nurse’s station because individuals with moderate-stage Alzheimer’s disease may experience confusion, memory loss, and wandering, which can lead to safety concerns. Close proximity to the nurse’s station allows for better supervision and prompt intervention.

Choice C rationale:

A client with schizotypal personality disorder may have unique care needs, but these typically do not require placement close to the nurse's station. The primary concern in this case is not related to the safety or wandering associated with Alzheimer's disease.

Choice D rationale:

A client with a history of alcohol use disorder may require monitoring and support but does not necessarily need to be placed close to the nurse's station solely based on this history. The primary concern is not related to Alzheimer's disease or safety due to wandering. In a healthcare setting, clients with Alzheimer's disease often experience confusion and may wander, creating a risk of harm to themselves. Placing a client with moderate-stage Alzheimer's disease close to the nurse's station allows for better supervision and prompt response to any safety concerns. Therefore, it is the most appropriate choice for close placement. .

Choice A rationale:

(Statement then rationale) Choice A is one of the correct options. Lanugo, fine hair growth on the body, is a common physical finding in individuals with anorexia nervosa. It occurs as a result of the body's attempt to conserve heat due to a lack of subcutaneous fat and can be considered a clinical sign of severe malnutrition.

Choice B rationale:

(Statement then rationale) Choice B is another correct option. Bradycardia, or a slow heart rate, is often seen in individuals with anorexia nervosa. The body's physiological response to severe malnutrition includes a slowed heart rate to conserve energy. Bradycardia is a result of the reduced metabolic demands and is a common cardiovascular finding in anorexia nervosa.

Choice C rationale:

(Statement then rationale) Choice C is not the correct option. Diarrhea is not typically associated with anorexia nervosa. Instead, individuals with this condition may experience constipation due to a reduced intake of food and fiber. Diarrhea is more commonly associated with other gastrointestinal disorders or conditions.

Choice D rationale:

(Statement then rationale) Choice D is also not the correct option. Hypotension, or low blood pressure, is not a common finding in individuals with anorexia nervosa. In fact, individuals with severe malnutrition may initially have normal or even elevated blood pressure. Hypotension is more commonly associated with conditions like dehydration or certain cardiac issues.

Choice E rationale:

(Statement then rationale) Choice E is the third correct option. Russell's sign is a finding in individuals with anorexia nervosa who engage in self-induced vomiting. It refers to calluses or abrasions on the knuckles or dorsum of the hand, resulting from the repetitive contact with the teeth while inducing vomiting. Recognizing Russell's sign is essential for assessing the severity of purging behaviors in individuals with anorexia nervosa. .
