Which of the following is responsible for causing acquired immunodeficiency syndrome?
Correct Answer
A. HIV
Explanation
HIV (Human Immunodeficiency Virus) is responsible for causing acquired immunodeficiency syndrome (AIDS). HIV attacks and weakens the immune system, specifically targeting CD4 cells, which are crucial for fighting off infections and diseases. As the immune system becomes compromised, individuals with HIV are more susceptible to opportunistic infections and certain types of cancers. Over time, if left untreated, HIV can progress to AIDS, which is characterized by severe immune system damage and a heightened risk of life-threatening illnesses. Therefore, HIV is the correct answer for the cause of acquired immunodeficiency syndrome.
5.
Which of the following may cause temporary strokelike symptoms?
Correct Answer
B. TIA
Explanation
TIA-(transient ishemic attack) causes temporary strokelike symptoms due to temporary interference in blood supply to brain cells.
6.
The abbreviation PTT stands for platelets.
Correct Answer
B. False
Explanation
PTT- Partial thromboplastin time: measures blood clotting time, used to monitor heparin therapy (heparin is another medication that slows clotting time)
7.
Lymphosarcoma is a type of cancer of lymphatic tissue not related to Hodgkin's disease.
Correct Answer
A. True
Explanation
Lymphosarcoma is indeed a type of cancer that affects the lymphatic tissue, but it is not related to Hodgkin's disease. This means that even though both conditions involve the lymphatic system, they are distinct and separate diseases. Therefore, the statement "Lymphosarcoma is a type of cancer of lymphatic tissue not related to Hodgkin's disease" is true.
8.
A murmur is an abnormal blowing or swishing sound in the heart caused by turbulent blood flow or backflow through a leaky valve.
Correct Answer
A. True
Explanation
A murmur is indeed an abnormal sound in the heart that is caused by turbulent blood flow or backflow through a leaky valve. This turbulent flow creates a blowing or swishing sound that can be heard with a stethoscope during a physical examination. Therefore, the statement is true.
9.
An aneurysm is a weakened area in the wall of a vessel.
Correct Answer
A. True
Explanation
An aneurysm is a medical condition characterized by a weakened area in the wall of a blood vessel. This weakened area can cause the vessel to bulge or balloon out, increasing the risk of rupture and potentially leading to serious complications such as internal bleeding. Therefore, the statement "An aneurysm is a weakened area in the wall of a vessel" is true.
10.
The abbreviation MI stands for muscle injury.
Correct Answer
B. False
Explanation
MI-myocardial infarction
11.
The abbreviation PTCA stands for a type of food.
Correct Answer
B. False
Explanation
PTCA- percutaneous transluminal coronary angioplasty
12.
The abbreviation CABG stands for coronary artery bypass graft.
Correct Answer
A. True
Explanation
The abbreviation CABG stands for coronary artery bypass graft, which is a surgical procedure used to treat coronary artery disease. In this procedure, a healthy blood vessel is taken from another part of the body and used to create a bypass around a blocked or narrowed coronary artery. This allows blood to flow more freely to the heart, relieving symptoms and reducing the risk of a heart attack. Therefore, the statement "The abbreviation CABG stands for coronary artery bypass graft" is true.
13.
An embolus is a soft blowing sound caused by turbulent blood flow.
Correct Answer
B. False
Explanation
embolus is undissolved matter floating in blood or lymph fluid that may cause an occlusion and infarct.
14.
The abbreviation CV stands for coronary vessel.
Correct Answer
B. False
Explanation
The abbreviation CV does not stand for coronary vessel. CV typically stands for curriculum vitae, which is a document that summarizes a person's education, work experience, and skills. In the medical field, CV can also stand for cardiovascular, referring to the heart and blood vessels. However, it does not specifically stand for coronary vessel.
15.
Ischemia refers to a temporary reduction in blood supply to a localized area of tissue.
Correct Answer
A. True
Explanation
Ischemia is indeed defined as a temporary reduction in blood supply to a localized area of tissue. This reduction in blood flow can lead to a decrease in oxygen and nutrient supply to the affected tissue, which can result in tissue damage or even cell death if not resolved promptly. Therefore, the statement "Ischemia refers to a temporary reduction in blood supply to a localized area of tissue" is true.
16.
The abbreviation ASHD stands for arteriosclerotic heart disease.
Correct Answer
A. True
Explanation
The correct answer is true because ASHD is an abbreviation for arteriosclerotic heart disease. Arteriosclerotic heart disease refers to the narrowing and hardening of the arteries that supply blood to the heart. This condition is commonly associated with the buildup of plaque in the arteries, leading to reduced blood flow and potential complications such as heart attacks or angina. Therefore, ASHD is a valid abbreviation for this specific heart disease.
17.
Fibrillation refers to an abnormal quivering of heart muscle fibers instead of an effective heartbeat.
Correct Answer
A. True
Explanation
Fibrillation is a medical term that refers to the abnormal quivering or twitching of the heart muscles. This condition disrupts the normal rhythm and coordination of the heartbeat, resulting in an ineffective pumping of blood. It can be a serious and life-threatening condition if not treated promptly. Therefore, the given statement that fibrillation refers to an abnormal quivering of heart muscle fibers instead of an effective heartbeat is true.
