NR 507: Advanced Pathophysiology Midterm Questions and
Answers
Question 1
What does the migration of WBCs to the bronchials do?
Correct Answer
increases inflammation of the cite and causes fibrosis in the bronchial wall
Question 2
cor pulmonale
Correct Answer
right-sided heart failure
Question 3
What causes blood to move from the atria to the ventricles
Correct Answer
gravity and atriole systole

,Question 4
What are two common causes of hypovolemia
Correct Answer
dehydration and hemorrhage
Question 5
Causes of right sided heart failure
Correct Answer
- pulmonary disease
- pulmonary hypertension
- RV MI
- RV Hypertrophy
- pulmonary SLV or tricuspid valve damage
- secondary to left heart failure
Question 6
what influences cardiac contractility (inotropic state)
Correct Answer
levels of electrolytes
High levels of ATP
level of oxygen available
synchronous muscle contraction

, Question 7
What are characteristics of epithelial cell metaplasia?
Correct Answer
squamous cells become nonciliated and are less protective; allow passage of toxins and WBCs
Question 8
alveolar hyperinflation
Correct Answer
When air is unable to move out of the alveolar like it should due to bronchial walls collapsing around possible mucus
plug thus trapping air inside
Question 9
How does Aortic SL valve or bicuspid valve damage lead to heart failure
Correct Answer
damage leads to back flow into the left atrium or ventricle after ejection
Question 10
Stimulation of what set a resting HR (chronotropic state)
Correct Answer
parasympathetic system
