Which skin infection causes redness, swelling, and tenderness to the touch and could occur as a complication of a lymphatic blockage?
Folliculitis
Cellulitis
Dermatitis
Impetigo
The Correct Answer is B
Cellulitis is a bacterial infection of the deep layers of the skin and subcutaneous tissue that causes redness, swelling, warmth, and pain in the affected area. It can occur as a complication of a lymphatic blockage because lymphedema (swelling due to impaired lymphatic drainage) can impair the skin's barrier function and make it more susceptible to infection.

Explanation
a. Hemiparesis: Both
- Higher fatality rate: Hemorrhagic CVA
- Rupture of vessel: Hemorrhagic CVA
- Loss of blood flow: Ischemic CVA
- Most common: Ischemic CVA
- 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 B
Explanation
A strain is an injury to a muscle or a tendon that occurs when it is stretched or torn beyond its normal range of motion. Strains can result from overextension of muscles or tendons, such as lifting a heavy object, twisting or bending awkwardly, or performing repetitive motions. Strains can cause bleeding and swelling in the affected area, as well as pain and reduced function.
