A nurse assesses a client on the medical-surgical unit. Which statement made by the client should alert the nurse to the possibility of hypothyroidism?

A. "My sister has thyroid problems.": While a family history of thyroid problems may increase the risk of developing thyroid disorders, this statement alone does not directly indicate hypothyroidism in the client. B. “I am always tired, even with 12 hours of sleep.": Fatigue or tiredness, even with adequate sleep, is a common symptom of hypothyroidism. An underactive thyroid leads to metabolic slowing, causing feelings of exhaustion despite sufficient rest. C. "Food just doesn't taste good without a lot of salt.": While a preference for salty food could occur in some individuals, it is not a common or specific symptom of hypothyroidism. This could be related to other factors, such as personal taste preferences or sodium intake. D. "I seem to feel the heat more than other people.": This statement suggests heat intolerance, which is more commonly associated with hyperthyroidism. In hypothyroidism, individuals tend to feel cold intolerance due to reduced metabolic activity.
