A nurse is caring for a client who has a diagnosis of Cushing syndrome. After performing magnetic resonance imaging (MRI), the underlying cause of the condition is found to be an ectopic ACTH-secreting tumor on the liver. Which of the following lab results would the nurse anticipate with this condition?

Elevated adrenocorticotropic hormone (ACTH) and elevated cortisol

Elevated adrenocorticotropic hormone (ACTH) and low cortisol

Low adrenocorticotropic hormone (ACTH) and elevated cortisol

Low adrenocorticotropic hormone (ACTH) and low cortisol

Answer and Explanation

The Correct Answer is A

A. Elevated adrenocorticotropic hormone (ACTH) and elevated cortisol: In cases of ectopic ACTH syndrome, the tumor produces ACTH, which stimulates the adrenal glands to produce excess cortisol. Therefore, both ACTH and cortisol levels are elevated.
B. Elevated adrenocorticotropic hormone (ACTH) and low cortisol: This scenario is less likely as elevated ACTH typically results in increased cortisol production, not decreased.
C. Low adrenocorticotropic hormone (ACTH) and elevated cortisol: This is characteristic of primary adrenal insufficiency, not ectopic ACTH syndrome, where ACTH levels are usually high.
D. Low adrenocorticotropic hormone (ACTH) and low cortisol: This pattern is inconsistent with Cushing syndrome, especially due to ectopic ACTH-secreting tumors, which typically result in elevated ACTH and cortisol.

Correct Answer is B

Explanation

A. Hyperthermia: This is not commonly associated with hypothyroidism. Hypothyroidism is more likely to lead to a decreased metabolic rate and hypothermia rather than hyperthermia.
B. Hyperlipidemia: This is a common condition associated with hypothyroidism. Hypothyroidism can lead to increased levels of cholesterol and triglycerides due to decreased metabolism.
C. Agitation: Hypothyroidism typically presents with symptoms such as fatigue and depression rather than agitation. Agitation is more commonly associated with hyperthyroidism.
D. Insomnia: Insomnia is more often associated with hyperthyroidism. Hypothyroidism usually leads to symptoms like fatigue and sleepiness rather than insomnia.

A. "You may need to repeat this therapy again in three weeks if the first dose doesn't achieve optimal results." B. "Avoid being close to pregnant women and children for 7 days after your treatment." C. "You may need to begin corticosteroid replacement therapy after this treatment." D. "The purpose of this therapy is to increase your levels of thyroid hormone."

Correct Answer is B

Explanation

A. "You may need to repeat this therapy again in three weeks if the first dose doesn't achieve optimal results": Radioactive iodine therapy may require additional doses, but this is not determined by a set timeframe such as three weeks. The need for additional therapy is based on the individual’s response and thyroid function tests.
B. "Avoid being close to pregnant women and children for 7 days after your treatment": This is correct as radioactive iodine therapy can emit radiation, and avoiding close contact with vulnerable populations such as pregnant women and children helps minimize their exposure to radiation.
C. "You may need to begin corticosteroid replacement therapy after this treatment": This is incorrect because corticosteroid replacement is not typically required after radioactive iodine therapy for Graves' disease. The treatment primarily targets the thyroid gland.
D. "The purpose of this therapy is to increase your levels of thyroid hormone": This is incorrect. The purpose of radioactive iodine therapy is to reduce thyroid hormone production by destroying thyroid tissue, which helps to manage hyperthyroidism in Graves' disease.
