basic pathology ( wound healing )

how long does it take for the first fibrin strands to begin forming after blood vessel rupture?

• roughly two minutes

• about five minutes

• approximately sixty seconds

• about ten seconds

how does healthy granulation tissue respond to injury?

• it does not bleed easily

• it bleeds profusely

• it turns black

• it forms scars immediately

Answer explanation

healthy granulation tissue is resilient and does not bleed easily

what is a common association of inflammation?

• improved circulation

• enhanced digestion

• increased heart rated

• tissue injury

Answer explanation

inflammation occurs as a response to tissue injury

under what conditions may loss of function occur in infammation?

• if there excessive oxygen in the area

• if cells lack nutrients or swelling interferes with their action.

• if nerves are completely damaged

• if the immune response is too strong

what is a consequence of increased capillary permeability during inflammation?

• hypotension

• dehydration

• constipation

• edema

what chemical mediator is responsible for increasing blood vessel permeability?

• cytokines

• kinins

• histamine

• prostaglandins

where do mature monocytes migrate from to participate in the inflammatory phase?

• from the lymphatic system

• from the bone marrow

• from the spleen

• from the bloodstream

what may occur if the barrier in the body is compromised?

• enhanced immune response

• infections may develop

• increased healing rate

• lowered risk of disease

Answer explanation

a compromised barrier allows easier entry for microorganisms, leading to infections.

which issue can significantly hinder the healing process?

• good nutrition

• adequate circulation

• circulatory problems

• youthfulness

Answer explanation

circulatory problems impede the delivery of nutrients and oxygen, essential for effective healing.

what happens during the initial phase after an injury involving damaged blood vessels?

• the remodelling phase begins immediately after the injury when damaged blood vessels leak transudate

• the proliferative phase begins immediately after the injury when damaged blood vessels leak transudate

• the healing phase begins immediately after the injury when damaged blood vessels leak transudate

• the inflammatory phase begins immediately after the injury when damaged blood vessels leak transudate

Answer explanation

the inflammatory phase is the first stage that occurs immediately after injury.
