a. Hemiparesis: Both

  1. Higher fatality rate: Hemorrhagic CVA
  2. Rupture of vessel: Hemorrhagic CVA
  3. Loss of blood flow: Ischemic CVA
  4. Most common: Ischemic CVA
  5. Altered sensorium: Both

Rationale: A cerebrovascular accident (CVA), or stroke, is a sudden interruption of blood supply to the brain, resulting in neurological damage. There are two main types of stroke: ischemic and hemorrhagic. Ischemic stroke occurs when a blood clot or plaque blocks an artery that supplies blood to the brain, causing tissue death due to lack of oxygen and nutrients. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue or the surrounding space. Both types of stroke can cause hemiparesis (weakness on one side of the body), altered sensorium (changes in consciousness, alertness, or orientation), and other neurological deficits depending on the location and extent of the damage. However, hemorrhagic stroke has a higher fatality rate than ischemic stroke because of the increased risk of intracranial pressure, cerebral edema, and brain herniation. Ischemic stroke is more common than hemorrhagic stroke, accounting for about 87% of all strokes.

Correct Answer is A

Explanation

This condition occurs when the blood supply to a part of the heart muscle is blocked, causing tissue damage or death. The symptoms of fatigue, shortness of breath, vomiting, chest pain, and elevated cardiac enzymes are all indicative of a myocardial infarction.

Correct Answer is D

Explanation

A thrombus is a blood clot that forms inside a blood vessel or the heart, which can obstruct blood flow and cause complications such as ischemia or embolism. One of the factors that predispose thrombus formation is stasis of blood flow, which means slow or stagnant movement of blood in a vessel or chamber, which can allow platelets and fibrin to accumulate and form a clot.
