LATEST ASSESSMENT ON ENDOCRINE FUNCTION LATEST

MULTIPLE CHOICE 1. The nurse correlates increased circulating levels of triiodothyronine and thyroxine to which physiological response? 1. Decreased secretion of thyrotropin-releasing hormone (TRH) 2. Decreased secretion of thyrocalcitonin 3. Increased secretion of thyroid-stimulating hormone (TSH) 4. Increased secretion of parathyroid hormone ANS: 1 Chapter number and title: 40, Assessment of Endocrine Function Chapter learning objective: 2.

As TRH secretion decreases, thyroid-stimulating hormone (TSH) secretion also decreases. 4 Parathyroid hormone secretion is not affected by circulating levels of T3 and T4. PTS: 1 CON: Metabolism 2. The nurse is preparing a teaching tool that focuses on the endocrine system. How should the nurse explain the negative feedback system? 1. Hormone secretion increases when circulating levels drop. 2. Hormone secretion increases when target organs send signals. 3. Hormone secretion increases when circulating levels increase. 4. Hormone secretion increases when the target tissue does not recognize the level. ANS: 1 Chapter number and title: 40, Assessment of Endocrine Function Chapter learning objective: 2.
