Abstract

There are limited or no effective interventions for recurrence of coronary heart diseases among the patients who smoke. Smoking cessation interventions has been suggested to have little benefit; however, there is little evidence on its cost- effectiveness and efficacy of such programs for cardiac inpatients. This study describes the efficacy and cost- effectiveness of intensive smoking cessation methods for cardiac patients admitted in the hospital cardiac unit. The experimental design assesses the efficacy and cost- effectiveness of the intervention that includes face- to- face counselling in combination with the nicotine replacement therapy using 8 cardiac wards of hospitals in ...

Chronic Obstructive Pulmonary Disease (COPD)

Introduction Chronic Obstructive pulmonary disease also known as COPD is a group of diseases which make breathing difficult by obstructing airflow and causing other breathing related problems (Centers for Disease Control and Prevention [CDC], 2015). This disease which is described by the National Heart, Lung and Blood Institute (NHLBI) as progressive because it worsens over time includes chronic bronchitis, emphysema and asthma in some cases (CDC, 2013; NHLBI, 2013a). In developing countries, poor quality of indoor air is suspected to play a major role in the disease development and progression whereas in the Unites States, tobacco smoke is reported ...

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 ...

Smoking has been evidently linked with the progression and exacerbation of coronary and hence cardiac conditions. Plaguing of the coronary arterial lumen due to smoking leads to the narrowing of the arterial lumen, hence leading to blockage of the coronary artery and subsequently, reduced cardiac output and the progression of a cardiac condition (Lloyd-Jones et al., 2010). In this regard, smoking cessation is pretty essential in arresting the exacerbation or progression of coronary disease after a post coronary intervention. In any health promotion intervention, evaluation of outcomes becomes an integral component as it places the implementer at a vantage ...

The blood requires a balance between alkaline as well as acid components to function appropriately. Such a balance is referred as acid-base balance. The lungs, as well as kidneys, function to maintain such balance. Whatever variation causes acid-base imbalance. High levels of acid are referred as acidosis, and high alkaline is referred as alkalosis. Metabolic acidosis, as well as alkalosis, results from kidneys problem. Respiratory alkalosis and acidosis occur because of lungs' problem (Schrier 162). The levels or concentrations of acid or alkaline are determined on a scale of pH. Acidity makes pH levels fall, and alkaline condition makes ...

Abstract

The literature defines hypertension as a medical condition experienced when the systolic blood pressure (BP) is equal or greater than 140 mm Hg or when the diastolic blood pressure is equal or greater than 90 mm Hg. Additionally, it offers a description of systematic, cellular, as well as molecular causes of hypertension. High blood pressure within the arteries is referred to as systemic hypertension (SH). The primary role of the systemic arteries is the transportation of oxygenated blood from the heart to the tissues of the body. The constriction of the arterioles (small arteries) is responsible for the high ...

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, ...

Introduction

This paper aims at evaluating concepts of alteration in homeostatic state, secondary to temporal variables. It analyses the case study of Brad, a 45-year old coal cutter who has held the job for 25 years. Brad is experiencing a chronic cough due to prolonged exposure to coal. Importantly, he has not been attending yearly checkups because he fears that his lung is “black.” The disease leads to fibrosis, reduced diffusing ability, and dilation of the small airways. In the final stage, the airways, alveoli, and pulmonary capillaries become damaged.

Mucor

Mucor is a type of fungal infection that caused by mold which is commonly found in plants, decaying fruits and vegetables, soil, manure and toxin of stored food. Mucor mainly effects the immunity compromised individuals and effects sinuses and lungs as it is usually inhaled during the breathing process. Fungus incorporates about 50 species some of them are prone to high temperatures and hence, they can cause infections mainly known as zygomycosis or mucormycosis. According to CDC (2015), mucormycosis effects the immunity comprised people at a higher pace and due to its contact with human body via inhalation, cut, ...

The primary cause of emphysema is smoking cigarettes. CH and other patients with emphysema are at risk of the destruction of the alveoli and different cancers, coronary artery diseases, heart failures, cerebral vascular diseases, osteoporosis, and some anxiety diseases. Emphysema is a complex respiratory disease and is usually associated with various systemic symptoms. A low BMI and relatively high rates of dyspnoea contribute to impaired exercise tolerance and promote a dreadful forecast beyond the respiratory obstruction. Emphysema sufferers are vulnerable to some conditions such as lung cancer, anemia, depression, coronary artery diseases, and dysfunctional skeletal myopathy. COPD has been ...

Describe the underlying pathology of COPD and the common pathological characteristics of the condition. Discuss the impact these pathological changes have on normal function, including how alveolar ventilation might be different in Mr Wenham compared to a normal individual. The hallmark pathological attributes of chronic obstructive pulmonary disease (COPD) are one, poorly reversible airflow obstruction and two, a progressive atypical inflammatory response within the lungs. The abnormal inflammatory response denotes the responses of the innate and adaptive immune systems to long-standing exposure to noxious gases and particles especially cigarette smoke. Notably, all cigarette smokers have some degree of inflammation ...

Emphysema is a type of COPD (Chronic Obstructive Pulmonary disease) that progressively damages the alveoli (air sacs) in the lungs and is mainly associated with smoking (Wells et al., 2012). The disease mainly causes breathing difficulties whereby this is associated with over-inflation of the air sacs in the lungs. As such, “barrel chest” configuration is among the key characteristics for emphysema whereby individuals suffering from the disease usually develop a “barrel chest” following progression of the disease. Based on the case study, the nurse would obviously expect the patient to have a “barrel chest” since he has had the ...

Introduction

Heart valve surgery is used for the repairing or replacement of valves of the heart that are diseased. The patients receive general anesthesia in this type of surgery whereby the surgeon makes a large surgical incision in the breastbone. The incision is meant to enable the surgeon to reach the aorta and the heart (Kato Paragraph 2). The relevance of stroke to the procedure of open-chest valve surgery is that it is one of the risks associated with cardiac surgery. Other risks include death, failure of the kidneys, cardiac arrest, irregular beats of the heart, and post-pericardiotomy syndrome (Kato ...

Acute coronary syndrome is an umbrella term for a group of clinical symptoms indicative of acute myocardial ischemia. These conditions include non-ST-segment elevation myocardial ischemia (NSTEMI), unstable angina, and ST-segment elevation myocardial infarction (STEMI). These conditions are high-risk manifestations of atherosclerosis in the coronary artery and significant causes of utilization of emergency services and hospitalization (Kumar and Cannon, 2009). STEMI causes 30% of all acute coronary syndromes in Australia (Harper and Lefkovits, 2010). This paper will describe the expected presentation, pathophysiology, ECG findings, pre-hospital management, and initial 24-hour management of STEMI in hospitals settings. These aspects will be described ...

Abstract

Ventilator-associated pneumonia (VAP) is an infection which often develops as a result of poor handling of mechanical ventilation. Such as, poor nursing practice in caring for patients with difficulty in breathing can lead to microorganisms entering patient’s body through a tube inserted especially via mouth and nose of the patient. When these microorganisms get into the respiratory system they cause lung infection which is referred to as ventilator-associated pneumonia (VAP). In preventing this infection, it is important that nurses adopt best practices to reduce the incidence of VAP and provide quality care that is aimed at improving the ...

Pathophysiology of Chronic venous insufficiency and Deep venous thrombosis

Chronic venous insufficiency is a condition that describes a dysfunction of the valves in the upper and lower extremities or the inability of the muscles in these regions to exert the required pressure that can force the flow of blood back into the heart. Essentially, the arteries are designed to supply oxygen-rich blood to all parts of the body while the veins are designed to transport the oxygen-deficient blood back into the heart (McPhee& Hammer, 2010). These processes are enhanced by the pressure exerted by the underlying muscles within the upper and lower extremities as well as the ability ...
