2ACUTE CARE IN NURSINGQuestion 1:Cushing syndrome is caused by excessive production or exposure to the hormone cortisol.Elaborating more on the hormone cortisol, it can be mentioned that this hormone is produced bythe adrenal cortex of the adrenal glands in the human body and is responsible for many keyphysiological function of the body. This hormone plays fundamental roles in maintaining andregulating the functionality of the cardiovascular system and helps in the task of maintaining theblood pressure of the body. On a more elaborative note, it has to be mentioned that there is anintricate hormonal signalling framework invested in the process of hypercortisolism. Theparaventricular nucleus present in the hypothalamus contains neuroendocrine neurons thatsecrete the corticotrophin releasing hormone or CRH (Brown et al., 2017). This hormone in turncontrosl the secretin of adenocorticotropin hormone or ACTH from the anterior lobe of thepituitary glands. Now the feedback loop of both of the hormone affects the adrenal cortex and inturn affects the cortisol hormone. Now Cushing’s syndrome is characterized by theoverproduction of cortisol hormone and there can be a few conditions that can lead to hisphenomenon. A tumor is the most likely cause, either in the pituitary gland, adrenal gland, orsomewhere else in case of ectopic Cushing syndrome. However another very common concernfor overproduction of the hormone cortisol is the prolonged usage of the corticosteroids. In thiscase the patient had been suffering from rheumatoid arthritis from the age of 15 year, and had toundergo a prolonged period of corticosteroid therapy, hence for the patient, this the mostplausible cause (Crespo Martín et al., 2016). Considering the incidence rate of the disease inAustralia, the statistics reveal that 1-2 people per 100000 individuals are suffering from thisdisease. The prevalence of this disease in Australia is close to 40 per 100000 people.
