Explanation Thyroid hormones are important for growth, development, metabolism , and maturation. The thyroid hormones interact with the growth hormone. They increase the sensitivity of many of the cells of the body to the effects of norepinephrine and epinephrine. Both these hormones are a part of the fight or flight response. Low levels of thyroid hormones result in a disorder known as hypothyroidism...

Summary Introduction

To review:

The disorder that is characterized by symptoms, such as sluggishness, depression, and intolerance to cold.

Introduction:

The thyroid gland is located in front of the throat and is similar in shape to a bowtie. In all vertebrates, it secretes the same hormones. The main hormones secreted by the thyroid gland are thyroxine and triiodothyronine. Both these hormones contain iodine in their structure. Therefore, iodine must be present in one’s diet for the production of thyroid hormones.

Clients who fail to take medications regularly are often admitted to the hospital repeatedly, and this can become quite expensive. How do you reconcile the client’s rights (to refuse treatment or medications) with the need to curtail avoidable health care costs? What is the quality of life for the client with schizophrenia who has a minimal response to antipsychotic medications and therefore poor treatment outcomes? Clients who take depot injections of antipsychotic medications are sometimes court-ordered to comply with this treatment when they are in the community. Does this violate the client’s right to self-determination or autonomy? When should clients have the ability to refuse such medications?
