Final answer:
Pneumonia is a common illness that affects people of all ages. In older adults, manifestations of pneumonia may include cognitive decline and impaired respiratory function.
Step-by-step explanation:
Pneumonia is a common illness that affects people in all age groups. It is a leading cause of death among the elderly and people who are chronically and terminally ill.
Many people suffer from multiple chronic health conditions in old age. The immune system becomes less efficient, increasing the risk of serious illnesses, such as cancer and pneumonia. As people age, the number of brain cells also decreases. Nearly half of those over the age of 85 years exhibit at least mild cognitive impairment. Diseases such as Alzheimer's disease that cause serious and permanent losses of mental function also become more common.
Pneumonia is a common inflammatory disease of the respiratory tract in which inflammation affects primarily the alveoli, which become filled with fluid that inhibits gas exchange. Most cases of pneumonia are caused by viral or bacterial infections. Vaccines are available to prevent pneumonia; treatment often includes prescription antibiotics. Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by chronic poor airflow, which causes shortness of breath and a productive cough.
Pneumonia is an illness that occurs when the alveoli, the tiny sacs in the lungs where gas exchange takes place, become inflamed and filled with fluid. When a person has pneumonia, gas exchange cannot occur properly across the alveoli. Pneumonia can be caused by many things. Infection by bacteria, viruses, fungi, or parasites can cause pneumonia. An injury caused by chemicals or a physical injury to the lungs can also cause pneumonia. Symptoms of pneumonia include cough, chest pain, fever, and difficulty breathing. Treatment depends on the cause of pneumonia. Bacterial pneumonia is treated with antibiotics.
From the given list of diseases, pneumonia best fits the description 'Alveoli become inflamed and fill with fluid.'
In an older adult client, manifestations of pneumonia may include cognitive decline and impaired respiratory function. It is important for healthcare professionals to be aware of these symptoms in order to provide appropriate care and treatment.
