What does the doctor assistant do?

2. A doctor assistant (or physician assistant) assists doctors in providing healthcare services, including examining patients, diagnosing illnesses, and developing treatment plans. 3. Checking vital signs means measuring the body's basic functions, including body temperature, pulse rate, respiration rate, and blood pressure. 4. A physical examination involves checking the patient's body for any signs of illness, including inspection, palpation (feeling), percussion (tapping), and auscultation (listening). 5. You can feel a pulse in several places, including the wrist (radial artery), neck (carotid artery), temple (temporal artery), or groin (femoral artery). 6. The pulse of a healthy adult at rest is typically 60-100 beats per minute. 7. Blood pressure is the force of circulating blood on the walls of the arteries. 8. A hypertensive patient often complains of headaches, dizziness, chest pain, or shortness of breath. 9. The heart lies in the chest cavity (mediastinum), slightly to the left of the sternum. 10. Anatomy studies the structure of the body, while physiology studies how the body parts function. 11. The body is made up of cells, which form tissues, organs, and systems. 12. The chief function of blood is to transport oxygen, nutrients, hormones, and waste products throughout the body. 13. The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves). 14. Hemoglobin transports oxygen from the lungs to the tissues and returns carbon dioxide from the tissues back to the lungs. 15. Plasma is the liquid component of blood containing clotting factors; serum is plasma without the clotting factors. 16. Our food consists of proteins, carbohydrates, fats, vitamins, minerals, and water. 17. Fats are found in oils, butter, fatty meat, dairy products, nuts, and seeds. 18. Proteins are necessary for building and repairing body tissues, as well as for making enzymes and hormones. 19. Antibiotic resistance occurs when bacteria change in response to the use of these medicines, making infections harder to treat. 20. Drugs can be administered orally (by mouth), intravenously (IV), intramuscularly (IM), topically (on the skin), or rectally. 21. The term "antibiotic" refers to a type of antimicrobial substance active against bacteria. 22. The stomach lies in the upper left part of the abdomen. 23. Food typically stays in the stomach for about 2 to 4 hours. 24. The liver performs many functions, including filtering blood, detoxifying chemicals, metabolizing drugs, and producing bile. 25. Immunity is the body's ability to resist infection or disease. 26. Immunity is provided by the immune system, including white blood cells, antibodies, and organs like the spleen and thymus.
