A nurse is assessing a client who has hypothyroidism. Which of the following findings should the nurse expect?

Choice A reason: Fatigue is a hallmark of hypothyroidism, as low thyroid hormone levels reduce metabolic rate, decreasing energy production via impaired ATP synthesis. This slows cellular processes, causing lethargy and weakness, making it a primary expected finding in clients with hypothyroidism. Choice B reason: Weight loss is not expected in hypothyroidism, which causes weight gain due to slowed metabolism and fluid retention from reduced thyroid hormone. Weight loss is more typical of hyperthyroidism, making this an incorrect finding for hypothyroidism. Choice C reason: Photophobia is not associated with hypothyroidism. It may occur in neurological or ocular conditions but not as a direct result of low thyroid hormone, which primarily affects metabolism and energy, making this an incorrect finding for the condition. Choice D reason: Exophthalmos, or bulging eyes, is a feature of hyperthyroidism (e.g., Graves’ disease), not hypothyroidism. Low thyroid hormone does not cause orbital inflammation or protrusion, making this an incorrect manifestation for a client with hypothyroidism.
