A 28-year-old female client who is in the first trimester of pregnancy is diagnosed with hyperthyroidism. Which of the following would be the preferred treatment for this client?

Radioactive iodine therapy

Levothyroxine

Ketoconazole

Propylthiouracil (PTU)

Answer and Explanation

The Correct Answer is D

A. Radioactive iodine therapy: This is contraindicated during pregnancy as it can harm the fetus and affect thyroid function.
B. Levothyroxine: This is used for hypothyroidism, not hyperthyroidism. For hyperthyroidism, this medication would not be appropriate.
C. Ketoconazole: This is an antifungal and is not used to treat hyperthyroidism.
D. Propylthiouracil (PTU): PTU is the preferred treatment during the first trimester of pregnancy for hyperthyroidism. It inhibits thyroid hormone synthesis and is considered safer than methimazole during early pregnancy.

Correct Answer is A

Explanation

A. B-type natriuretic peptide (BNP): BNP levels are elevated in heart failure due to increased pressure and stretch in the heart's chambers. It is a key marker used to diagnose and assess the severity of heart failure.
B. Troponin I: This marker is used to diagnose myocardial infarction (heart attack) rather than heart failure. Elevated troponin levels indicate damage to the heart muscle.
C. Blood urea nitrogen (BUN): BUN levels can be elevated in heart failure due to decreased renal perfusion, but it is not as specific for diagnosing heart failure as BNP.
D. Platelet levels: Platelet levels are not directly related to the diagnosis of heart failure. They are more relevant for assessing clotting disorders and other conditions.

A. Elevated adrenocorticotropic hormone (ACTH) and elevated cortisol B. Elevated adrenocorticotropic hormone (ACTH) and low cortisol C. Low adrenocorticotropic hormone (ACTH) and elevated cortisol D. Low adrenocorticotropic hormone (ACTH) and low cortisol

Correct Answer is A

Explanation

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.
