Hypovolemic shock
Hypovolemic shock is noted by McCance and Huether (2010) to be an emergency condition in which severe fluid and blood loss makes the victim's heart unable to sufficiently pump enough blood to the victim's body. This kind of shock is noted by McCance and Huether (2010) to result in multiple organ failure.
Brief case scenario presenting a patient who has experienced this type of shock
Mrs. Robertson was presented to the hospital with pale skin, was slipping into unconsciousness and sweating very heavily. She had been involved in a motor accident and had suffered massive hemorrhage on her left thigh. Her systolic blood pressure was 92 mmHg, and matched that of aperson suffering from stage 3 hypovolemic shock. Her leg had no pulse and fell unconscious after hemorrhaging profusely from the left thing. Her Cardiac output could not be maintained by arterial constriction. She had increase respiratory rate and increase diastolic pressure. Her pulse rate was to narrow.Afer first aid; she gained consciousness but was restless.
Associated pathophysiology
The condition is characterized by a massive loss in an individual's intravascular volume that subsequently results in a decreased level of preload. Due to the fact that preload is one of the main determinants of stroke volume, the cardiac output automatically falls. The very initial case of hemodynamic abnormality of fluid loss inadvertently activates the rather compulsory mechanism under the control of the neuroendocrine system which maintains an adequate level of central perfusion irrespective of reduced level of cardiac output. Systemic vasoconstriction can however lead to hypoxia, tissue ischemia and ultimately to alteration of cellular function as well as global organ dysfunction in the worst case scenario (Worthley,2000).
Treatment of hypovolemic shock
The management of hypovolemic shock is critical since the condition is...
The husband's physical recovery did not indicate the life changes they must contend with. These changes included grief over the loss of intimacy between them, the changes in the nature of their relationship, misguided individual expectations, a lack of interpersonal communication and the lack of professional information to help and enlighten them. The process of trying to recover sexual function led them to seek out many treatment modes. Most
There are three main treatment options. For tumors that are still inside the prostate, a surgery called radical prostatectomy and radiation therapy are common treatment options (Prostate cancer treatment options). This source describes these two options. Radical prostatectomy removes the whole prostate gland and the nearby lymph nodes. There are 2 types of radiation therapy, external beam radiation therapy and seed therapy also called brachytherapy. In external beam radiation therapy,
Prostate cancer is a type of cancer that develops in the male reproductive system, and most prostate cancer can be slow growing. However, there are still aggressive type of prostate cancers, because the cancer cells can spread from the prostate of a patient to all other part of the body particularly the lymph nodes and bones. Initially, prostate cancer may reveal no symptom, however, in a later stage, it can

Later, I have provided short literature reviews of four articles. Lung Cancer Lungs are those organs in the body that help the human beings to breathe i.e. inhale and exhale oxygen. Their primary function is to provide oxygen to every cell in the body.
