WORKSHEET 3: Discussion Questions and Answers
1.4 Discussion Questions
1. Explain the difference between signs and symptoms and give some examples of each.
Answer: Signs are evidence of disease observed on physical examination, such as an abnormal pulse, abnormal respiratory rate, fever, and sweating. Symptoms are indications of disease reported by the patient, such as pain, dizziness, and itching.
2. Explain the difference between syndromes and disorders.
Answer: A syndrome is an abnormal structure or function characterized by a group of signs and symptoms that usually occur together. A disorder is a functional abnormality not necessarily linked to a specific cause or physical abnormality.
3. There are five physical examination procedures. Pick two and describe them.
Answer:
Inspection refers to a visual examination of the external surface of the body, its movements, and posture for abnormalities or evidence of disease.
Palpation, feeling the body with fingers or hands, allows examination of the size, consistency, texture, location, and tenderness of an organ or body part.
Auscultation, listening to the lungs, heart, and intestines, allows evaluation of the frequency, intensity, duration, number, and quality of sounds originating in the body.
Percussion, producing sounds by tapping on specific areas of the body with fingers, hands, or small instruments, allows evaluation of the size, consistency, and borders of the body organs, and the presence or absence of fluid in the body area.
Vital signs (pulse, respiratory rate, blood pressure, temperature) are measures of various physiological statistics in order to assess the most basic body functions. Normal vital signs vary with age, sex, weight, exercise tolerance, and physical condition.
4. Explain the difference between a CT scan and an MRI.
Answer: Computed tomography (CT scan) uses computers and x-rays to create three-dimensional images of internal structures. Magnetic Resonance Imaging (MRI) analyzes tissue responses to a strong magnetic field to create images of internal structures.
5. Explain the difference between diagnosis and prognosis.
Answer: Diagnosis is the process of identifying a disease or disorder. Prognosis is the predicted outcome of the disease.
6. Explain the difference between mortality and morbidity.
Answer: Morbidity is the number of deaths that occur among people with a certain disease. Morbidity is the number of cases of a disease in a population.
7. There are nine chief causes of disease. Describe three giving an example for each.
Answer:
Hereditary - caused by an abnormality in an individual's genes or chromosomes. [Hemophilia, sickle cell anemia, cystic fibrosis]
Congenital - exists at date of birth, can be acquired through hereditary or acquired during development in the uterus. [Tetralogy of Fallot]
Degenerative - the function or structure of the affected tissues or organs progressively deteriorates over time. [Arteriosclerosis, osteoarthritis, Alzheimer's]
Inflammatory, autoimmune, and allergic - result of abnormal immune function. [Asthma, systemic lupus erythematosus, hay fever]
Infectious diseases are caused by pathogens like bacteria and viruses. [Tuberculosis, influenza, syphilis]
Neoplastic - result from abnormal growth that leads to the formation of tumors. [Lung cancer, malignant melanoma, breast cancer]
Metabolic - disruption of normal metabolism, the process of converting food to energy on a cellular level. [Diabetes, hypothyroidism, gigantism]
Traumatic - physical or chemical injury. [Burns, frostbite, bone fractures]
Nutritional - related to overconsumption or under consumption of nutrients. [Iron-deficiency anemia, scurvy, obesity]
