Answer 2

The environment which is most crucial to the development of skin pigmentation is the intensity of incident UV radiations.

The Environment may be defined as the surroundings or conditions in which a person, animal, or plant lives or operates and performs its specific functions.

Melanocyte stimulating hormone is responsible for the pigmentation of the skin. It is highly produced in hot, warm, and humid conditions. So, the skin color of Caribbean people may be found to be dark.

Physician notes:
A 45-year-old obsess woman presents complaining of menorrhagia with cramping pelvic pain, dizziness when standing, and rapid heart rate. Manual physical examination demonstrates multiple enlarged masses in her uterus. Blood workup reveals low RBCs [red blood cells] and hematocrit [% of RBC in a volume of blood], normal WBCs and platelets, and slightly elevated blood sugar level. U/S [ultrasound] of the abdomen and pelvis shows multiple fibroids [leiomyomas] of the uterine wall. Patient is admitted to the hospital with recommendation for hysterectomy. During the course of admission she peaks to the resident dietitian about a compulsive eating disorder and agrees to undergo therapy at the hospital’s weight loss clinic.

Using the information presented in these notes, select the principal diagnosis from the following:
Pelvic pain – female
Obesity
Anemia
Menorrhagia
Fibroid uterus

Answers

Answer:

Menorrhagia

Explanation:

Using the process of elimination, because her bloodwork test results seem to be adequate, Anemia can be ruled out, as well as obesity. Although pelvic pain can be severe, it can be treated without hospitalization. A Fibroid uterus is an abnormality but does not always require treatment, but because of Menorrhagia, a Hysterectomy will be necessary in order to stop excessive bleeding and severe discomfort.

Over that last few months, Sara has been complaining of severe stomach issues, regular head- and backaches, difficulty breathing, and a very significant change in her menstrual cycle. Her doctor has recommended she rest and return to work after a few days. Her doctor will most likely give Sara reading material on __________ to look over while she rests. A. conversion disorders B. hypochondriasis C. somatization disorders D. Munchausen’s syndrome Please select the best answer from the choices provided A B C D

Answers

Explanation:

the answer is hypochondriasis

The most likely reading material that Sara's doctor will give her while she rests would be on somatization disorders.

What is Somatization disorder ?

Somatization disorder is a condition in which a person experiences physical symptoms that have no medical explanation and are believed to be related to psychological factors such as stress or anxiety.

The symptoms that Sara is experiencing are not easily explained by a specific medical condition, and her doctor has recommended rest, which suggests that there may be a psychological component to her symptoms.

By providing reading material on somatization disorders, her doctor can educate Sara on the potential psychological causes of her symptoms and help her better understand her condition.

Somatic symptom disorder is not the same as hypochondriasis, which is characterized by a preoccupation with having a serious illness despite medical reassurance that no such illness exists.

Conversion disorder involves the presence of physical symptoms that are related to an underlying psychological conflict or stressor, while Munchausen's syndrome involves the deliberate fabrication or exaggeration of symptoms for attention or personal gain.
