Delayed wound healing is seen in all except
1) Malignancy
2) Hypertension
3) Diabetes
4) Infection
Oral medicine
Answer: 2
While hypertension can have various health implications, it is not typically
associated with delayed wound healing. In contrast, malignancy, diabetes, and
infection are known to impair the healing process.
Wound contraction can be most effectively minimized by
1) Split skin graft
2) Full thickness grafting
3) Allowing secondary granulation
4) Dressing with placenta
Oral medicine
Answer: 2
Full thickness grafting is effective in minimizing wound contraction because it provides a more stable and vascularized tissue bed for healing
What is the prevalence of Huntington's disease in the general population?
1) 1/1000
2) 1/10,000
3) 1/100,000
4) 1/1,000,000
Huntington's disease has a prevalence of approximately 10 per 100,000 people in the general population. It is more common in certain ethnic groups, particularly those of Western European descent.
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.
A 65-year-old male with a history of hypertension is admitted for an acute exacerbation of chronic obstructive pulmonary disease (COPD). His current medication includes metoprolol. Which of the following is a possible adverse effect of metoprolol that could be relevant to his condition?
(1) Bronchospasm
(2) Peripheral edema
(3) Bradycardia
(4) Tachycardia
Metoprolol is a beta-blocker, which can cause bronchospasm as a side effect, particularly in patients with a history of respiratory conditions like asthma or COPD. It is important to monitor patients with respiratory diseases closely for signs of bronchospasm when prescribing beta-blockers.
In a patient with a history of chronic obstructive pulmonary disease (COPD), which of the following is NOT a common side effect of long-term inhaled corticosteroid therapy?
1) Oral thrush
2) Pneumonia
3) Osteoporosis
4) Tachycardia
Long-term inhaled corticosteroid therapy is commonly used in COPD management to reduce inflammation and exacerbations. Common side effects include oral thrush, pneumonia due to immunocompromise, and osteoporosis due to steroid-induced bone loss. Tachycardia is not a typical side effect of inhaled corticosteroids.
What is the normal heart rate for an adult?
1) 60-80 beats/min
2) 70-90 beats/min
3) 80-100 beats/min
4) 100-120 beats/min
The normal resting adult heart rate is typically between 60 and 80 beats per minute.
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.
