MSN 570 ADVANCED
PATHOPHYSIOLOGY EXPECTED
QUESTIONS WITH VERIFIED ANSWERS
• What does conducting zone do? -✓✓conducts air to respiratory zone, humidifies,
warms, and filters air
• Blood Brian Barrier -✓✓The barrier system that restricts the passage of various
chemicals and microscopic entities between the bloodstream and the central nervous
system. It still allows for the passage of essential substances such as oxygen.
• Atropine Neurotransmitters -✓✓Atropine is a muscarinic receptor antagonist that is
used to inhibit the effects of excessive vagal activation on the heart, which is manifested
as sinus bradycardia and AV nodal block. Therefore, atropine can temporarily revert
sinus bradycardia to normal sinus rhythm and reverse AV nodal blocks by removing
vagal influences.
• Beta-adrenergic receptor blockers -✓✓-Blocks NE/Epi effects on heart - less Ca++
entry
-Decreases force of cardiac contractions
• Asthma -✓✓A chronic allergic disorder characterized by episodes of severe breathing
difficulty, coughing, and wheezing. Obstructive
• cardiac output -✓✓heart rate x stroke volume
• Most common cancer mutation? -✓✓Acquired
• missense mutation -✓✓A base-pair substitution that results in a codon that codes for a
different amino acid.
• multiple sclerosis -✓✓A chronic disease of the central nervous system marked by
damage to the myelin sheath. Plaques occur in the brain and spinal cord causing
tremor, weakness, incoordination, paresthesia, and disturbances in vision and speech
• Treachers-Collins Syndrome -✓✓An autosomal dominant gene disorder that affects
first and second arch structures of the zygomatic and mandible. In severe cases,
patients will have a fish-like appearance in the face and may have deafness and mental
retardation.
• Conducting Zone -✓✓nose, pharynx, larynx, trachea, bronchi, bronchioles
