If a gall stone becomes lodged in the ileum, it can cause blockage and lead to symptoms such as abdominal pain, nausea, and vomiting. The ileum is a common site for gall stones to become impacted due to its narrow diameter and the presence of certain anatomical structures that can trap the stones.Rate this question:

Zero order kinetics is followed by all of the following except?
- A.
Phenytoin
- B.
Ethanol
- C.
Barbiturates
- D.
Both a and b
Correct Answer
C. BarbituratesExplanation
Zero order kinetics refers to a type of drug metabolism where the rate of elimination remains constant regardless of the drug concentration. Phenytoin and ethanol are known to follow zero order kinetics, meaning their elimination rate is independent of their concentration. However, barbiturates do not follow zero order kinetics. Therefore, the correct answer is barbiturates.Rate this question:

Frequent changes in glasses is associated with which of the following diseases
- A.
Senile cataract
- B.
Closed angle glaucoma
- C.
Open angle glaucoma
- D.
Vitreous haemorrhage
Correct Answer
C. Open angle glaucomaExplanation
Frequent changes in glasses are often associated with open angle glaucoma. This is because open angle glaucoma causes a gradual loss of peripheral vision, which can result in the need for frequent changes in glasses prescription. This condition is characterized by increased pressure in the eye, which can damage the optic nerve and lead to vision loss if left untreated. Therefore, individuals with open angle glaucoma may experience changes in their vision that require adjustments to their glasses prescription.Rate this question:

Cough is an adverse effect seen in administration of which of the following
- A.
Nifedipine
- B.
Enalapril
- C.
Frusemide
- D.
None
Correct Answer
B. EnalaprilExplanation
Enalapril is an angiotensin-converting enzyme (ACE) inhibitor commonly used to treat high blood pressure and heart failure. One of the adverse effects associated with enalapril is cough. This cough is believed to be caused by the accumulation of bradykinin, a substance that is normally broken down by ACE. When ACE is inhibited by enalapril, bradykinin levels increase, leading to irritation and coughing. Therefore, cough is a known side effect of enalapril administration.Rate this question:

Drug which can be safely used in pregnancy is
- A.
Tetracycline
- B.
Heparin
- C.
Warfarin
- D.
Both b and c
Correct Answer
B. HeparinExplanation
Heparin is the correct answer because it is considered safe to use during pregnancy. Tetracycline and warfarin, on the other hand, are contraindicated in pregnancy due to their potential harmful effects on the developing fetus. Heparin, a blood thinner, is commonly used in pregnancy to prevent blood clots and is not known to cause any significant harm to the fetus. Therefore, it is the drug of choice when anticoagulation therapy is required during pregnancy.Rate this question:

Cauliflower ear is due to?
- A.
Hematoma of the ear
- B.
Otitis externa
- C.
Mastoiditis
- D.

A. Hematoma of the earExplanation
Cauliflower ear is a condition that occurs due to hematoma of the ear. Hematoma refers to the accumulation of blood in the ear, usually as a result of trauma or injury to the ear. When blood collects in the space between the cartilage and the perichondrium (the connective tissue that covers the cartilage), it can lead to the deformation and swelling of the ear, giving it a cauliflower-like appearance. Therefore, hematoma of the ear is the correct explanation for cauliflower ear.Rate this question:

ECG is suggestive of?
- A.
Atrial fibrillation
- B.
Atrial flutter
- C.
SVT
- D.
Wolf Parkinson White syndrome
Correct Answer
B. Atrial flutterExplanation
The correct answer is Atrial flutter. Atrial flutter is a type of abnormal heart rhythm characterized by a rapid and regular atrial contraction. This can be identified on an ECG by the presence of sawtooth-shaped flutter waves, typically occurring at a rate of 250-350 beats per minute. Atrial fibrillation, on the other hand, is characterized by irregular and chaotic atrial contractions, while SVT (supraventricular tachycardia) refers to any rapid heart rhythm originating from above the ventricles. Wolf Parkinson White syndrome is a specific type of SVT characterized by an accessory pathway in the heart.Rate this question:

Deficiency of lysyl hydroxylase causes?
- A.
Alport syndrome
- B.
Epidermolysis bullosa
- C.
None
- D.
Menkes disease
Correct Answer
D. Menkes diseaseExplanation
Menkes disease is caused by a deficiency of lysyl hydroxylase. Lysyl hydroxylase is an enzyme that is responsible for modifying collagen, a protein that provides strength and structure to connective tissues. Without lysyl hydroxylase, collagen cannot be properly formed, leading to the characteristic symptoms of Menkes disease, including developmental delays, neurological abnormalities, and abnormal hair growth. Alport syndrome is caused by mutations in genes encoding type IV collagen, not lysyl hydroxylase. Epidermolysis bullosa is caused by mutations in genes encoding proteins involved in maintaining the integrity of the skin. Therefore, the correct answer is Menkes disease.Rate this question:
