What is the typical age range for increased risk of coronary heart disease in men?
1) ? 45 years
2) ? 55 years
3) ? 65 years
4) ? 75 years
According to the provided risk factor list for atherosclerosis, men are considered at increased risk for coronary heart disease starting at the age of 45 years.
What is the typical age of onset for the increased risk of coronary heart disease in men?
1) ? 45 years
2) ? 55 years
3) ? 65 years
4) ? 75 years
Men generally have an earlier onset of coronary heart disease compared to women, and the risk increases significantly after the age of 45.
What is the primary function of the mitral valve in the heart?
1) To prevent backflow of blood from the aorta into the left ventricle during diastole
2) To prevent backflow of blood from the pulmonary artery into the right ventricle during systole
3) To prevent backflow of blood from the left atrium into the left ventricle during systole
4) To prevent backflow of blood from the vena cava into the right atrium during systole
The mitral valve is crucial in preventing the backflow of blood from the left atrium to the left ventricle during systole, ensuring that blood flows in the correct direction through the heart during the cardiac cycle.
Which is a non-absorbable suture
1) Polypropylene
2) Polyglycollic acid
3) Vicryl
4) Collagen
Oral medicine
Answer: 1
1. Polypropylene: This is a synthetic, non-absorbable suture material known
for its strength and resistance to infection. It is commonly used in oral
surgery and dental procedures due to its non-reactive nature with tissues.
2. Polyglycollic acid: Polyglycollic acid is an absorbable suture material that
is broken down by hydrolysis.
3. Vicryl: Vicryl is a synthetic, absorbable suture material that is commonly
used in dentistry due to its good handling properties and tissue reactivity
profile.
4. Collagen: Collagen is a natural, absorbable suture material derived from
animal sources. It is biocompatible but not as strong as non-absorbable
materials and is absorbed by the body over time.
Which of the following antiprotozoal agents is not indicated for the treatment of giardiasis?
(1) Nitazoxanide
(2) Furazolidone
(3) Metronidazole
(4) Quinacrine
Nitazoxanide and furazolidone are both indicated for the treatment of giardiasis caused by Giardia lamblia. Metronidazole is also effective against anaerobic bacterial infections but is not primarily used for giardiasis. Quinacrine is an antimalarial agent and is not used to treat protozoal infections such as giardiasis.
What is the treatment for respiratory alkalosis?
1) Inhalation of carbon dioxide
2) Injection of sodium bicarbonate
3) Ingestion of antacids
4) Increase in respiratory rate
The treatment for respiratory alkalosis typically involves correcting the underlying cause. However, if symptoms are severe, inhalation of a small amount of carbon dioxide can be administered.
Which of the following is NOT a common symptom of valvular heart disease?
1) Shortness of breath
2) Rapid heartbeat
3) Chest discomfort
4) Abnormal body temperature
Valvular heart disease symptoms typically include weakness on exertion, rapid heartbeat, chest discomfort, and fainting spells. However, an abnormal body temperature is not a common symptom associated with valvular heart disease.
A patient with a history of hypothyroidism presents with fatigue, cold intolerance, and weight gain. The most likely cause of these symptoms is:
1) Subclinical hypothyroidism
2) Hyperthyroidism
3) Thyroid cancer
4) Adrenal insufficiency
The symptoms of fatigue, cold intolerance, and weight gain are more consistent with hypothyroidism than hyperthyroidism. Subclinical hypothyroidism is a milder form of hypothyroidism where the patient may have a normal T4 level but an elevated TSH level.
