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

Myxedema represents severe hypothyroidism characterized by markedly reduced thyroid hormone (T3/T4) levels leading to decreased metabolic rate, accumulation of glycosaminoglycans in interstitial tissues, and systemic slowing of cardiovascular, gastrointestinal, and neurologic function. Rationale: A. Facial edema occurs due to mucopolysaccharide (glycosaminoglycan) deposition in interstitial tissues causing non-pitting edema. Myxedema produces characteristic puffy face, periorbital swelling, and thickened skin. This reflects severe hypothyroid state with fluid retention in tissues rather than vascular overload. B. Diarrhea is associated with increased gastrointestinal motility seen in hyperthyroidism. Myxedema causes reduced bowel motility leading to constipation. This option contradicts the expected hypometabolic state where slowed peristalsis and reduced intestinal activity are prominent clinical features. C. Heat intolerance is a hallmark of hyperthyroidism due to increased metabolic heat production. Myxedema results in decreased thermogenesis and cold intolerance. This option reflects opposite endocrine pathology and is inconsistent with the low metabolic state seen in severe hypothyroidism. D. Tachycardia is associated with sympathetic stimulation in hyperthyroidism. Myxedema typically causes bradycardia due to reduced beta-adrenergic responsiveness and low metabolic demand. This option contradicts the expected cardiovascular depression and slowed heart rate seen in severe thyroid hormone deficiency.
