In paragraph format may I have help with the following four questions? Thank you.

The client was involved in a motor vehicle accident and sustained a significant head injury as well as severe damage to his back. The health care provider has ordered a stimulation test.

1. What is the rationale for ordering the stimulation test for this client?

2. Why would you be concerned if the client sustained damage to his pituitary gland?

3. Explain the difference between positive and negative feedback in the endocrine system.

4. List advantages and disadvantages of various diagnostic tests for endocrine dysfunction.

Solution

The rationale for ordering the stimulation test for this client is to study the functioning of the pituitary gland after the accident as it is a case of head injury. If the client sustained damage to his pituitary gland which is the master gland; which produces critical hormones, which control various bodily functions like; the anterior lobe is involved in sexual maturation, development and reproduction. The intermediate lobe releases a hormone that control pigmentation by stimulating melanocytes. The posterior lobe releases antidiuretic hormone. The positive increases of the hormone level when required; hence it is feed forward the and negative feedback controls the deviation from the normal physiological range, and hence maintains homeostasis. It is feedback mechanism. Advantages include the fact that the testing protocol are simple and results a quick to get. The disadvantages of various diagnostic tests for endocrine dysfunction include the fact that poor test sensitivity continues to be a major hurdle as it leads to false negative result
