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

A. Correct. Propylthiouracil (PTU) is an antithyroid medication used to treat hyperthyroidism, including Graves' disease. It can sometimes cause agranulocytosis, a condition characterized by a severe reduction in white blood cells, which can lead to symptoms like a sore throat and fever. These symptoms should be reported immediately.

B. Constipation is not a common side effect of propylthiouracil. If it occurs, it is usually not an urgent concern, and can often be managed with dietary and lifestyle changes.

C. Increased urine output is not typically associated with propylthiouracil. It is more likely to be seen with diuretic medications or conditions like diabetes.

D. Painful, excessive menstruation is not a direct side effect of propylthiouracil. However, hormonal changes related to hyperthyroidism can affect menstrual patterns. If the client is experiencing significant changes in menstrual bleeding, it should be reported to the healthcare provider, but it may not be considered an immediate emergency.

A. Incorrect. Palpitations, which are rapid or irregular heartbeats, are more commonly associated with hyperthyroidism, where there is an excess of thyroid hormones.

B. Incorrect. Diaphoresis, or excessive sweating, is not typically associated with hypothyroidism.

C. Incorrect. Exophthalmos, or bulging of the eyes, is a characteristic finding in hyperthyroidism (specifically Graves' disease) and is not typically seen in hypothyroidism.

D. Correct. Weight gain is a common finding in hypothyroidism. The slowing down of metabolic processes due to insufficient thyroid hormones can lead to an increase in body weight.
