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.

The inter-tidal zone refers to an area that is under water during a high tide and exposed to the air at low tides. Organisms living in the inter-tidal zone must be adapted to living in an extreme environment. They must be able to survive for sometime without water and in water that can be high or low in salinity. The nearshore zone is always under water and is the area where waves can break in their approach to the shore. Organisms here are adapted to living completely submerged in water.
