A nurse is caring for a client who reports increased anxiety and nervousness, heat intolerance, and unintentional weight loss. Blood testing reveals decreased thyroid-stimulating hormone (TSH), elevated thyroxine (T4), and elevated triiodothyronine (T3) levels. Which of the following vital sign abnormalities does the nurse anticipate?

Hypotension

Tachycardia

Slow respiratory rate

Decreased body temperature

Answer and Explanation

The Correct Answer is B

A. Hypotension: Hyperthyroidism typically causes increased cardiac output and can lead to normal or elevated blood pressure, not hypotension.

B. Tachycardia. Elevated thyroid hormones increase metabolic rate and sympathetic nervous system activity, leading to tachycardia.

C. Slow respiratory rate: There is no direct effect of hyperthyroidism on respiratory rate.

D. Decreased body temperature: Hyperthyroidism is associated with increased metabolism, which can lead to heat intolerance and increased body temperature, not decreased.

Correct Answer is A

Explanation

A. Myxedema coma. Myxedema coma is a severe, life-threatening complication of untreated or undertreated hypothyroidism. It manifests with severe hypothyroid symptoms such as hypothermia, altered mental status, and can lead to coma and death if untreated.

B. Goiters: Enlarged thyroid gland due to various causes but not typically life-threatening.

C. Sjogren's syndrome: An autoimmune disorder affecting moisture-producing glands, not directly related to hypothyroidism.

D. Hashimoto's disease: An autoimmune disorder causing hypothyroidism but not directly associated with life-threatening complications like myxedema coma.

A. "You have had a gastrointestinal bleed." B. "You have fewer red blood cells." C. "You have an autoimmune disease." D. "You have a low ferritin level."

Correct Answer is B

Explanation

A. "You have had a gastrointestinal bleed.": While this can cause fatigue due to anemia, it's not directly related to sickle cell anemia.

B. "You have fewer red blood cells." Sickle cell anemia causes chronic hemolysis, leading to anemia and fatigue. The characteristic sickle-shaped cells are less flexible and prone to hemolysis, resulting in fewer functional red blood cells and reduced oxygen-carrying capacity.

C. "You have an autoimmune disease.": Sickle cell anemia is not an autoimmune disorder.

D. "You have a low ferritin level.": Ferritin levels may be affected, but the primary cause of fatigue in sickle cell anemia is anemia itself, not low ferritin.
