Fundamentals of Applied Pathophysiology: An Essential Guide for Nursing and Healthcare Students
Ian Peate
THIRD EDITION
About this book
The third edition brings with it a number changes but at the same time it has aimed to preserve its user-friendly approach. Inviting and listening to feedback from readers has allowed me to retain features that have been seen as helpful, to introduce new features and to reorganise some of the chapters. Illustrations are again used in abundance to assist in understanding and appreciating complex disease patterns that are being discussed. Applying a fundamental approach will provide readers with a crucial understanding of applied pathophysiology. I have introduced a series of new activities that are intended to help you learn in an engaged way and to apply your learning when you are in the care setting, wherever this may be. This third edition provides you with an up-to-date overview of pathophysiology and important issues related to care. This edition also considers the wider context of care provision supplementing a nursing focus by broadening the professional base to embrace all healthcare students. In providing care that is contemporary, safe and effective an integrated, multidisciplinary approach is an absolutely essential requirement for those who provide care as well those who manage it. The healthcare student is an important member of any multidisciplinary care team, and this edition also emphasises the multidisciplinary approach and acknowledges the fact that care is delivered in ever changing environments to a range of people and communities. As with the first and second editions, this text has also been written with the intention of making the sometimes complex subject of pathophysiology accessible and exciting.
Questions & Answers from this book
Questions and answers are connected to the referenced book and its available source material.
Chapter 1: Cell and body tissue physiology
Chapter 2: Cancer
How does the lifetime risk of developing breast cancer differ between men and women according to the chapter?
The lifetime risk of developing breast cancer is significantly higher for women than for men, with a risk of 1 in 11 for women compared to 1 in 1000 for men.
What are the common signs and symptoms of Acute Lymphoblastic Leukaemia (ALL) as described in the chapter?
Common signs and symptoms of Acute Lymphoblastic Leukaemia (ALL) include increased lethargy, persistent fever, recurrent infections, prolonged bleeding, easy bruising, pallor, enlarged lymph nodes, and pain in the abdomen, bones, and joints. CNS involvement can lead to headaches and vomiting.
What are the common signs and symptoms of lung cancer as mentioned in the chapter?
Common signs and symptoms of lung cancer include dyspnoea (difficulty in breathing), haemoptysis (coughing up blood), chronic cough and wheezing, chest or abdominal pain, cachexia, fatigue, loss of appetite, dysphonia (hoarse voice), and difficulty in swallowing.
Chapter 3: Inflammation, immune response and healing
What are the three main processes that occur simultaneously during the inflammatory response following tissue injury?
The three main processes that occur simultaneously during the inflammatory response following tissue injury are mast cell degranulation, activation of plasma protein systems, and movement of phagocytic cells to the injury site.
How do endogenous infections differ from exogenous infections according to the chapter?
Endogenous infections originate from micro-organisms that are already present within the body, while exogenous infections come from external sources. Endogenous infections occur when these internal micro-organisms become pathogenic due to their presence in inappropriate locations within the body.
Chapter 4: Shock
How does distributive shock differ from hypovolaemic shock according to the chapter?
Distributive shock differs from hypovolaemic shock primarily in the status of circulating blood volume. In distributive shock, the blood volume remains normal, but there is widespread vasodilatation leading to decreased peripheral vascular resistance, which impairs cardiac output and blood pressure. In contrast, hypovolaemic shock is characterized by a reduction in circulating fluid volume due to fluid loss, resulting in decreased venous return to the heart and subsequently lower cardiac output and blood pressure.
What are the common causative factors of neurogenic shock as described in the chapter?
Common causative factors of neurogenic shock include spinal cord injury, spinal anaesthetic, brain injury, vasomotor depression, drug overdose, and severe pain.
Chapter 5: The nervous system and associated disorders
Chapter 6: The heart and associated disorders
Chapter 7: The vascular system and associated disorders
Chapter 8: The blood and associated disorders
How does the cerebrospinal fluid contribute to the protection of the brain?
Cerebrospinal fluid (CSF) protects the brain by surrounding it in a cushion of fluid, which absorbs shocks and jolts. This cushioning effect helps prevent damage to nerve roots, meninges, and blood vessels during changes in motion.
What is the role of the blood-brain barrier in protecting the brain?
The blood-brain barrier protects the brain by acting as a filter between brain tissue and blood-borne substances, preventing harmful toxins and metabolites from entering the brain.
Chapter 10: The respiratory system and associated disorders
How does the Glasgow Coma Scale (GCS) help in identifying possible brain trauma according to the chapter?
The Glasgow Coma Scale (GCS) helps identify possible brain trauma by assessing a patient's level of consciousness through their eye, verbal, and motor responses. A decrease in GCS, as seen in the case study where Julian's score fell from 13 to 11, can indicate worsening brain injury or complications such as increased intracranial pressure.
What are the common signs and symptoms of increased intracranial pressure (ICP) as mentioned in the chapter?
Common signs and symptoms of increased intracranial pressure (ICP) include decreasing levels of consciousness, headache, sluggish pupil reaction, visual disturbances, abnormal breathing patterns, and impaired motor responses.
Chapter 11: The gastrointestinal system and associated disorders
Chapter 12: Nutrition and associated disorders
Chapter 13: The endocrine system and associated disorders
Chapter 14: The reproductive systems and associated disorders
Chapter 15: Pain and pain management
What non-pharmacological interventions are recommended for patients with angina according to the chapter?
Recommended non-pharmacological interventions for patients with angina include adopting a healthy diet low in saturated fats, engaging in leisure activities like walking and swimming, encouraging weight loss for overweight patients, advising against excessive alcohol consumption and smoking, and regular monitoring of blood pressure.
What are the three types of angina mentioned in the chapter on pain and pain management?
The three types of angina mentioned are stable angina, unstable angina, and variant angina.
Chapter 18: The skin and associated disorders
Chapter 19: The ear, nose and throat, and eyes, and associated disorders
