Question

1. Cholesterol involved in atherosclerosis is taken up by which of the following pathways?
A) noncellular
B) oxidative
C) receptor dependent
D) scavenger

2. Which of the following is not thought to be associated with edema in hepatic failure patients?
A) lymphatic obstruction
B) increased hydrostatic pressure
C) decreased osmotic/oncotic pressure

3. Liver cirrhosis represents which type of liver dysfunction?
A) pre hepatic
B) intra hepatic
C) post hepatic

4. Which of the following statements is correct?
A) A patient has a clot in their femoral vein. The clot broke from that site and traveled in the blood to lodge in the pulmonary artery. This is a thrombus.
B) A patient has a clot in their femoral vein. The clot broke from that site and traveled in the blood to lodge in the pulmonary artery. This is an embolism.

5. Which of the following is the most common early complication of a myocardial infarction?
A) arrhythmias
B) rupture of the heart
C) renal failure
D) congestive heart failure

Answer 1

1.D) scavenger pathway

LDL is taken by the scavenger receptor cells in blood vessel endothelium and it gets oxidised to form plaque in atherosclerosis.

2.A)lymphatic obstruction

Edema is collection of fluid in the interstitial space,it occurs due to increased hydrostatic pressure and decreased oncotic pressure in hepatic failure patients.

3.B)intra hepatic

It is caused by alcohol and hepatitis B virus ,damages the liver ,it is a chronic condition.

4.B)A patient has a clot in their femoral vein.The clot broke from that site and traveled in the blood to lodge in the pulmonary artery.This is an embolism

Movement of broken clot is embolus ,whereas thrombus is only blood clot.

5.A)arrhythmias

Ventricular arrhythmias - due to ischemia is the early and most common complication of myocardial infarction ,onset is less than 4 hr.
