Loop ODiuretics O- OCORRECT OANSWER O-Prefix O"emide" OFurosemide.
Mechanism Oof Oaction: OBlock Owater Oreabsorption Oin Othe Oloop Oof OHenle Oof Othe
Onephron. OIncreases Ourine Ooutput.
AE: Odecreased OK+, Odecreased OBP, OOtotoxicity, Onephrotoxicity.
OContradictions: Oauditory, Orenal Oimpartments
During Odiastole, Owhich Opart Oof Othe Oheart Ois Ofilling Owith Oblood? O- OCORRECT OANSWER
O-Both Oventricles. OSystole Oreflects Othe Operfusing Opressure Oof Othe Ocardiovascular
Osystem Owhere Othe Oventricles Oeject Oblood Ofrom Othe Oheart. OOnce Ocomplete, Oa Oresting
Operiod—diastole—follows, Owhere Oblood Omust Orefill Othe Oventricles Odirectly Ofrom Othe
Ocollection Othat Ooccurred Oin Othe Oatria.
Oxygenated Oblood Oflows Othrough Owhich Ovessel? O- OCORRECT OANSWER O-Pulmonary
Ovein. OThe Osuperior Ovena Ocava Ocarries Oall Othe Odeoxygenated Oblood Ofrom Operipheral
Ocirculation Oback Oto Othe Oheart Owhere Oit Oenters Othe Oright Oatrium Oto Obe Opumped Ointo
Othe Oright Oventricle. OThe Oright Oventricle Opumps Oto Othe Olungs Ofor Ooxygenation Ovia Othe
Opulmonary Oartery. OAfter Opulmonary Ocirculation, Othe Ooxygenated Oblood Ois Ocarried Oback
Oto Othe Oheart Ovia Othe Opulmonary Ovein.

Oflexibility Oof Oa Oblood Ovessel Owall. OWithout Ovascular Ocompliance, Othe Ovessel Owall
Obecomes Omore Origid Oand Osusceptible Oto Orupture O(i.e., Oan Oaneurysm).
,Which Ocomplex O(wave) Orepresents Othe Osum Oof Oall Oventricular Omuscle Ocell Odepolarizations?
O-
CORRECT OANSWER O-The OQRS Owave Oof Oan Oelectrocardiogram O(ECG Oor OEKG) Orepresents
Othe Olargest Ospike Oin Oelectrical Oactivity Oof Othe Oheart, Oas Oventricular Omuscle Ocells Operform

hypertension? O- OCORRECT OANSWER O-Angiotensin OII Oleads Oto Omyocardial Ohypertrophy, Opoor
myocardial Ocompliance, Oand Oventricular Odilation Othrough Ostimulating Oincreased Ocardiac
Opreload Oand Oafterload Oand Odirect Otoxicity Oto Omyocardial Ocells. OIt Ocauses Osarcomere

Othrough Onumerous Ostages Oof Odevelopment Oleading Oto Oa Odeveloped Oheart Owith
Odistinct Oatria, Oventricles, Oand Ocardiac Ovessels.
Which Ocompensatory Omechanism Ois Ospontaneously Oused Oby Ochildren Odiagnosed Owith
Otetralogy Oof OFallot O(TOF) Oto Orelieve Ohypoxic Ospells? O- OCORRECT OANSWER O-
Spontaneous Osquatting Ohelps Orelieve Ohypercyanotic Oevents Oin Oolder Ochildren Othrough
Oincreasing Osystemic Ovascular Oresistance,
decreasing Ovenous Oblood Oreturn. OThis Oprovides Oa Olarger Oamount Oof Ooxygenated Oblood
Ofor Othe Obody Oand Oleads Oto Othe Otemporary Oreversal Oof Oblood Othrough Othe Oventricular
Oseptal Odefect O(VSD), Owhich Oresults Oin Oincreased Opulmonary Oflow. OSquatting Ois Orarely
Oseen Oclinically Obecause Omost OTOF Odefects Oare Odiagnosed Oand Osurgically Orepaired Oin
Oinfancy
Which Ocondition Ois Oconsistent Owith Othe Ocardiac Odefect Oof Otransposition Oof Othe Ogreat
Ovessels? O-
CORRECT OANSWER O-The Oaorta Oarises Ofrom Othe Oright Oventricle. OIn Otransposition Oof Othe
Ogreat
vessels, Oopposite Oof Oa Onormal Oheart, Othe Oaorta Oarises Ofrom Othe Oright Oventricle, Oand Othe
Opulmonary Oartery Oarises Ofrom Othe Oleft Oventricle.
A O26-year-old Ofemale Opresents Oto Ourgent Ocare Owith Ocomplaints Oof Oextreme Ofatigue,
Omuscle Oaches, Oabdominal Opain, Onumbness Oand Otingling Oin Oher Oextremities, Oand
Obloating. OShe Oexplains Othat Oshe Ohas Obeen Oexperiencing Ogastrointestinal Oupset Oafter
Omeals Oand Ohas Onot Ohad Oa Obowel Omovement Ofor Othe Opast Ofour Odays. OShe Oreports
Ousing Oover-the-counter, Oanti-diarrheal Oproducts Olast Oweek Oto
