A client who has a history of hypothyroidism was admitted with lethargy and confusion. Which additional finding warrants immediate action by the nurse?

Choice A reason: A haematocrit of 30% is below the normal range and indicates anaemia, which is common in hypothyroidism. However, it does not require immediate intervention compared to a decline in consciousness.Choice B reason: Facial puffiness and periorbital enema are common signs of hypothyroidism but do not require immediate intervention. They are more indicative of chronic, rather than acute, issues.Choice C reason: A further decline in level of consciousness is critical and warrants immediate action. It can indicate a myxoedema coma, a severe complication of hypothyroidism that is life-threatening and requires urgent treatment.Choice D reason: Cold and dry skin is a common symptom of hypothyroidism but does not require immediate intervention compared to a decline in consciousness.
