What is expected to happen to malaria-carrying mosquitoes in the coming century?
iragen [17]

They will spread to non-endemic regions, especially in highlands areas. This is attributed to global warming that is resulting in increased global temperatures.

An adult client with suspected hypothyroidism is scheduled for a thyrotropin-releasing hormone (TRH) stimulation test to evaluat
polet [3.4K]

Answer: Serum thyroid-stimulating hormone test would confirm secondary hypothyroidism.

Explanation:

The serum thyroid stimulating hormone (TSH) test involves the intravenous administration of a small amount of Thyroid Releasing Hormone (TRH) and the measurement of TSH levels at some points following the administration.

The first step involves collecting the blood sample of the patient and measuring the baseline TSH prior to the intravenous administration of TRH. Blood sample is drawn again 30 minutes after TRH administration, and TSH level is measured and compared to the baseline measurement.

If there is slight or no increase in serum TSH level following TRH administration, it is secondary hypothyroidism because the cause of the hypothyroidism is in the anterior pituitary gland. This means that the pituitary gland is not secreting TSH because it is diseased.
