Q

Exercise effects on BP,HR, CO

A

Exercise increases HR and CO, and DECREASE in overal Systemic Vascualr REsistance (due to vasodilation in muscles, )
There is vasoconstriction (peripherally + systemic systolic BP) in areas not needing as much blood only overall there is vasodilation / systemic vascular resistance (from local adenosine, K+, ATP, CO2, Lactate)
==== LOW resistance in total systemic vascular resistance + pulmonary resistance

Q

If mother is not aa only marries man that is aa and has family sister with aa (AR disorder) what is the probability of child being aa

A

Mom can either be AA or Aa since she does not have disease (she needs Aa to transmit to baby = 2/3 chance) + then baby has 1/2 chance = 1/3 chance of baby havin git

19
Q

Paroxysmal nocturnal Hemoglobinuria does what to kidney

A

Injur due to hemoglobin release

20
Q

LAD proximal section vs LAD distal section

A
Proximal = septum and ant LV

  1. Cardiac tamponade , restrictive pericarditis
  2. Asthma /COPD

= due to RV enlargement

23
Q
Heparin function (PT or PTT) 
Warfarin function (PT or PTT)
A
Heparin = PTT
Warfarin = PT
24
Q

How do Bronchodilators work

A

Increase cAMP in smooth muscles = dilates bronchioles

25
Q

NFkB and IkB are found where

A

When attached (cytoskeleton) when IkB kinase ubiquinizes the IkB and makes NFkB active it goes into nucleus to transcribe cell proliferation and inflammation

26
Q

Furosemide works on what channel and what drug should patients on loop diuretic avoid

A

Na/K/2Cl
= ascending limb of LOH (Na, Cl, fluid excretion)
= PGE release —> renal flow and increased GFR

(Avoid NSAIDS that block PGE and decrease GFR)

27
Q

HEP A inflammatory cells involved and histo
