Answer:
Iodine in the food items included in the diet
Explanation:
The thyroid hormones (T3 and T4) are the lipid-soluble hormones and are formed when iodine is attached to the amino acid tyrosine. The triiodothyronine (T3) has three atoms of iodine while tetraiodothyronine (T4) has four atoms of iodine attached to the benzene rings of tyrosine.
Hence, the synthesis of T3 and T4 hormones by thyroid gland depends on the availability of iodine atoms which in turn mostly comes from the diet.
Active transport of iodide ions occurs from the blood into the cytoplasm of the follicular cells of the thyroid gland. In fact, most of the iodide ions are concentrated in the follicular cells of the thyroid gland in the body. Diet serves as a source of iodine and the diet deficient in iodine leads to malfunctioning of the thyroid gland.

The immune response is the body's defense mechanism against the pathogens. The immune response of the body protects it from bacteria, viruses and multiple other disease causing organisms. The normal development of this protective immune response of the body is produced by as a result of the hormones which are produced by the thymus gland. The thymus gland produces the T-lymphocytes, which are important for a healthy immune response. The thymus gland secretes thymosin which is crucial for the development of these cells.
Hence, the answer is 'thymus gland'.
The nursing action should be checking of residual every four to six hours, follow protocol for slowing or withholding feedings for excess residual volumes in which some facilities hold for residual volumes of 100 or 200 ml then restart at the lower rate after a period of rest, check pump for proper operation and ensure feeding infused at correct rate.
