what is a nosocomial infection? what is a congenital disorder? what are the causes of congenital disorders?

Explanation:

• Nosocomial Infection: An infection acquired in a hospital or other healthcare facility, often from exposure to pathogens in that environment (e.g., MRSA from hospital surfaces/equipment).
• Congenital Disorder: A condition present at birth, caused by genetic, environmental, or a combination of factors (e.g., Down syndrome, spina bifida).
• Causes of Congenital Disorders:
• Genetic: Mutations (e.g., cystic fibrosis), chromosomal abnormalities (e.g., Turner syndrome).
• Environmental (Prenatal): Maternal infections (e.g., rubella, Zika), exposure to toxins (e.g., alcohol, drugs), nutritional deficiencies (e.g., folate deficiency for neural tube defects).
• Multifactorial: Interaction of genes and environment (e.g., cleft lip/palate).

Answer:

• Nosocomial Infection: An infection acquired during a stay in a healthcare facility (hospital, clinic, etc.), from exposure to pathogens in that setting (e.g., from contaminated medical equipment, healthcare workers, or other patients).
• Congenital Disorder: A health condition present at birth, resulting from genetic, environmental, or combined factors affecting fetal development.
• Causes of Congenital Disorders:
• Genetic: Chromosomal abnormalities (e.g., Down syndrome), single - gene mutations (e.g., sickle - cell anemia).
• Environmental (Prenatal): Maternal infections (e.g., rubella virus causing birth defects), exposure to teratogens (e.g., alcohol in fetal alcohol syndrome, certain medications), nutritional deficiencies (e.g., folate deficiency leading to neural tube defects).
• Multifactorial: Interaction of genetic predisposition and environmental triggers (e.g., cleft lip/palate, some heart defects).
