Multiple Choice Questions

Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

Introduction

The exchange of respiratory gas is limited by the capacity of the respiratory muscles to circulate air in the lung. Ventilation fails when muscles do not have the capacity to cope with the load brought by the mechanics of the pulmonary system. It is crucial to comprehend the mechanics of respiration/breathing not only for purposes of diagnosing how the system has failed and to offer the correct prescription for treatment of the failure, but to be capable of providing the most effectual temporary respiratory support through the use of a mechanical ventilator, as well. The first category explains the ...

Introduction

Research in lung cancer treatment can save lives and improve a patient’s quality of life. There are three main types of lung cancer: Non-small cell, small cell, and lung carcinoid cancer. Non-small cell lung cancer, such as Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma make up about 85% of all lung cancers (Molina, Yang, Cassivi, Schild, & Adjei, 2008). Both environmental and genetic factors are significant in the cause of lung cancer. Chronic exposure to carcinogens, ionizing radiation, and viral infections can lead to alterations of the DNA in tissue lining the bronchial epithelium of the lungs. Furthermore, ...

Introduction

Pulmonary edema (PE) is characterized by the accumulation of fluid in the parenchyma and air spaces of the lungs. Most often PE is associated with respiratory failure and impaired gas exchange. Globally, PE is known to be characterized by two major factors, the first is associated with the injury of the lung parenchyma which is termed as non-cardiogenic pulmonary edema. The second is associated with the failure of the left ventricle of the heart to release blood from the pulmonary circulation within the system and is termed as cardiogenic pulmonary edema (Glaus, Schellenberg , and Lang. 2010). The major cause ...

Application of the Natural Law Theory in the Management of a Case in Relation with the Ethical and Religious Directives for Catholic Health Care

Introduction

Natural laws are principles with reasons used to examine the human nature and are set by the natural world. These natural laws in most cases use justification to examine the nature of humans and try to explain morality and ethics basing on the religious perspective. Additionally, natural laws often are joined with common laws and norms of the societies but in most cases these natural laws contend that specific rights and values are acquired genetically from parents. In addition, these natural laws are related to ethical and religious directives for catholic health care which actually stipulate the bioethics ...
