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?

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.

A. They are more prone to hyperthermia and may require cooling measures: Hypothyroidism typically leads to hypothermia (lower body temperature) rather than hyperthermia. Clients with hypothyroidism are more likely to experience difficulty maintaining normal body temperature.
B. Their levothyroxine should be held for 3 days prior to and after the surgery: Levothyroxine should not be held before or after surgery without specific guidance from the healthcare provider. Maintaining consistent thyroid hormone levels is crucial for clients with hypothyroidism.
C. They are at risk of developing tachycardia and should be given propranolol: Hypothyroidism is more commonly associated with bradycardia (slow heart rate) rather than tachycardia (fast heart rate). Propranolol is used to manage symptoms of hyperthyroidism, not hypothyroidism.
D. They are more sensitive to the effects of opioids and may require lower doses: Clients with hypothyroidism often have a reduced metabolic rate, which can increase their sensitivity to medications, including opioids. Therefore, they may require lower doses of opioids to avoid adverse effects.
