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 ...

Compare The Pathophysiology Of Chronic Venous Insufficiency And Deep Venous Thrombosis. Describe How Venous Thrombosis Is Different From Arterial Thrombosis. There are various similarities and differences between the pathophysiology of chronic venous insufficiency and deep venous thrombosis. In order to appreciate the pathophysiology of chronic venous insufficiency, it’s important to understand the peripheral venous systems which act as a reservoir and conduit system for storing blood and returning it to the heart. For this system to function properly, it needs a series of valves and muscular pumps that convey blood from the lower-extremity levels of the venous system, ...

Ventilator-associated pneumonia

Abstract The intensive care unit in most hospitals plays the role of providing care to patients dealing with life-threatening conditions. The technological and other set ups in these hospital units are vital in ensuring that these patients continue to receive the best regarding care while with the intentions of having them emerge with desirable outcomes. There are however challenges relating to the care that these patients receive since, in most cases, they are usually under mechanical ventilation. A patient under this condition faces the risk of developing ventilator-associated pneumonia if the ventilators are not handled with the required care. ...

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

Abstract

Factor V Leiden is a genetic mutation that confers resistance to the action of activated protein C and thus predisposes to venous thromboembolism. It’s inherited as an autosomal dominant trait and is prevalent amongst Caucasians with a carrier rate of 4%. Deep venous thrombosis and pulmonary embolism are the most common clinical manifestations of FVL related VTE although it can also affect other sites. Genetic testing for FVL is used for diagnostic as well as predictive purposes. Diagnosis of FVL is based on protein assays and

DNA analysis technology. Familial genetic testing for FVL is generally not recommended except in ...
