W12 worksheet: endocrine case.

Follow the instructions below very carefully. Many of the items in this assignment require reading, or videos, or something else to do. Each question has either a text box that can be filled out or a box that can be checked to show completion. Be sure to type out your answers completely and expand the text boxes if you need the additional space.

Question 1 --- 3 points

Endocrine case study.

The endocrine system secretes different types of hormones directly into the bloodstream. Some of these hormones are transported on carrier proteins and some are dissolved directly in the plasma. Our hormones regulate a large range of physiological functions. If a person experiences hormonal dysfunction, physiological homeostasis is lost, and symptoms arise. Medical professionals trying to track down a cause for a patient’s symptoms and complaints must know the endocrine system well in order to recognize when hormonal imbalance might be the cause.

This lab will present some signs and symptoms and ask you to do your own research to track down likely endocrine dysfunctions as possible sources of the problems. Go through this Endocrine System Case Study (links to an external site) quick tutorial that will give you good advice on how to navigate and complete this case study.

Provided below..

Dr. Nee decided that Mary was suffering from three different endocrine dysfunctions. Give the names of three possible conditions that you have decided are likely.

Your answer: Graves Disease, hyperparathyroidism, and a tumor in the pituitary.

Question 2 --- 3 points

What additional diagnostic test(s) and/or result(s) would help you confirm your diagnosis and why? Be sure to explain how each test result will help you confirm your diagnosis of conditions you came up with for question 1.

Your answer: I would do a MRI to confirm a tumor in the pituitary gland. Which would cause her headache and affected sight.

Question 3 --- 12 points

Here is a quick summary of Mary’s blood values that were not in normal ranges:

 Blood Osmolality: Decreased  Calcium: Increased  T3 and T4: Increased  TBG: Decreased  TRH: Decreased  TSH: Decreased  TSI: Increased  ACTH: Decreased  PTH: Increased  LH: Increased  Estrogen: Increased  FSH: Increased  GHrH: Increased  GH: Decreased  GnRH: Decreased

Start with the first one in this list and explain why it is high or low. Do this for all the items in the list. We are looking to see if you can use the pathophysiology of the conditions you came up with to explain all of the blood lab values.

Your answer: She has been drinking a higher volume of water due to her headache so would decrease the osmolality of her blood. Due to the increase of T3 and T4 there is a higher activity of her thyroid which would cause her skin to be warmer to the touch. There are signs of high activity of the parathyroid which would increase calcium in the blood. She has the signs of Graves’

Your answer: Due to there being signs of a tumor in the pituitary gland there can be pressure on the optic nerves affecting sight and could be affected by Graves’ Disease.

Question 6 --- 2 points

Provide a good rationale as to why Mary’s blood osmolality is the value that it is.

Your answer: Her blood osmolarity would be low due to her drinking a higher amount of water for her headache and with her being dehydrated from diarrhea and the she could be feeling more thirsty which is a side affect of Graves Disease.
