A nurse in a clinic is caring for a client who has a new diagnosis of hypothyroidism. Which of the following findings should the nurse expect?
A.
Palpitations
B.
Weight gain
C.
Diaphoresis
D.
Protruding eyeballs
The Correct answer and Explanation is:
The correct answer is B. Weight gain.
Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating metabolism, heart function, digestion, and overall energy balance. When thyroid hormone levels are low, the body’s metabolism slows down, leading to a variety of clinical manifestations.
Explanation of the Correct Answer:
Weight gain is a common symptom of hypothyroidism. Due to the slowed metabolism, the body burns fewer calories at rest, resulting in weight gain, even if the client maintains the same diet and activity levels. The weight gain is often mild to moderate but can become significant if the hypothyroidism is left untreated. This occurs because the body is unable to effectively convert food into energy, leading to the accumulation of fat and water retention.
Explanation of Incorrect Answers:
- A. Palpitations: Palpitations are typically associated with hyperthyroidism, where there is an excess of thyroid hormones. Hyperthyroidism causes the heart to beat faster and may lead to sensations of a racing heart or palpitations. In contrast, hypothyroidism tends to slow down the heart rate (bradycardia).
- C. Diaphoresis: Diaphoresis, or excessive sweating, is more commonly seen in hyperthyroidism. Hypothyroid clients often experience cold intolerance and dry skin because their metabolic rate is low, leading to decreased heat production. They tend to feel cold even in warm environments and have reduced sweating.
- D. Protruding eyeballs (exophthalmos): Exophthalmos is a hallmark symptom of Graves’ disease, a form of hyperthyroidism. It is not associated with hypothyroidism. In hypothyroidism, clients may instead present with facial puffiness and swelling around the eyes (periorbital edema), but not exophthalmos.
Other Symptoms of Hypothyroidism:
Clients with hypothyroidism may experience fatigue, constipation, depression, dry and brittle hair, hoarseness, and joint or muscle pain. The condition is usually diagnosed through laboratory tests that show low levels of T4 and elevated thyroid-stimulating hormone (TSH), as the body attempts to stimulate the underactive thyroid gland.
Hypothyroidism is typically treated with synthetic thyroid hormone replacement, such as levothyroxine, to restore normal hormone levels and alleviate symptoms like weight gain.
