What is a pathological angiogenesis?
Release of inflammatory mediators
Formation of new vessels in response to injury
Excessive or abnormal blood vessel growth
Inhibition of vessel formation
The Correct Answer is C
Choice A reason: Release of inflammatory mediators drives inflammation, not angiogenesis. Pathological angiogenesis is excessive or abnormal vessel growth, often in diseases like cancer, so this is incorrect for the term.
Choice B reason: New vessel formation in response to injury is physiological angiogenesis, not pathological. Pathological angiogenesis involves abnormal, excessive growth, so this is incorrect for the described process.
Choice C reason: Pathological angiogenesis is excessive or abnormal blood vessel growth, seen in conditions like tumors or retinopathy. This matches the definition, making it the correct choice for the term.
Choice D reason: Inhibition of vessel formation is anti-angiogenic, not pathological angiogenesis. Excessive vessel growth defines the pathological state, so this is incorrect for the term.

Correct Answer is C
Explanation
Choice A reason: Antibiotics treat bacterial infections, but inspiratory stridor, cough, and tachypnea suggest acute airway obstruction, like croup or bronchospasm. Antibiotics are not immediate for these symptoms, as they address infection, not airway narrowing, making this a lower-priority treatment.
Choice B reason: Sputum culture identifies pathogens but is not urgent for inspiratory stridor, which indicates airway compromise needing immediate relief. Cultures guide long-term therapy, not acute management, making this an incorrect priority for the patient’s presentation.
Choice C reason: Inhaled bronchodilators, like albuterol, are the priority for inspiratory stridor, nonproductive cough, and tachypnea, as they relax airway smooth muscles, relieving bronchospasm or narrowing. This addresses acute airway obstruction, common in conditions like asthma or croup, making it the correct treatment.
Choice D reason: History of illness exposure informs diagnosis but delays treatment for acute airway symptoms. Inspiratory stridor requires immediate intervention to ensure airway patency, making history-taking secondary to addressing the urgent respiratory distress, thus an incorrect priority.
Correct Answer is A
Explanation
Choice A reason: Atherosclerosis erodes the vessel wall by forming plaques that weaken arterial layers, promoting aneurysm formation. This degenerative process destabilizes the wall, making it the correct effect in aneurysm development.
Choice B reason: Ischemia of the intima is not a primary atherosclerosis effect; plaques cause wall damage, not just intimal ischemia. Vessel wall erosion is more accurate for aneurysm formation, so this is incorrect.
Choice C reason: Atherosclerosis narrows vessels but doesn’t primarily obstruct them in aneurysm formation. Wall erosion and weakening lead to dilation, not blockage, so this is incorrect for aneurysm development.
Choice D reason: Atherosclerosis reduces nitric oxide, impairing vasodilation, but this isn’t directly linked to aneurysms. Vessel wall erosion by plaques is the key mechanism, so this is incorrect for the effect.
