Pulse pressure is the difference between systolic blood pressure and diastolic blood pressure, and is
widened in which of the following disorders? (A) Early hypovolemic shock (B) Increased ICP (C) Cardiac
tamponade (D) Neurogenic shock correct answers (B) Increased ICP [pulse pressure is narrow in early
shock, cardiac tamponade, and aortic valve stenosis]
Parents bring in their 4-week-old infant with non-bilious projectile vomiting and persistent hunger.
Which of the following conditions is suspected? correct answers (A) Pyloric stenosis [PS is characterized
by non-bilious projectile vomiting and persistent hunger; volvulus has bilious vomiting]
Systemic vascular resistance (SVR) is decreased in which type of shock? correct answers (D) Distributive
[Afterload (pressure) is low in distributive shock (neurogenic, septic, anaphylactic) due to vasodilation,
and high in all other forms of shock due to vasoconstriction]
Which is the following is the hallmark symptom of Prinzmetal's angina? correct answers Pain at rest due
to coronary vasospasm; may be seen with stimulant use
ST segment elevation in ECG leads II, III and aVF indicates injury to which area of the heart? correct
answers Inferior wall [V1-V4 look at the anterior wall; I, aVL, V5, V6 look at the lateral wall of the left
ventricle]
A 40F who is 36-weeks pregnant presents to the ED with painless bright red vaginal bleeding. The nurse
knows a pelvic exam is contraindicated since the most likely cause of the bleeding is correct answers
Placenta previa [think P's - painless privates, placenta previa; abrupt placenta - always painful]
A 14-year-old c/o lightheadedness & palpitations. Which cardiac disorder is characterized by a short PR
interval and a Delta wave? correct answers Wolff-Parkinson-White (WPW) syndrome [WPW is
characterized by a short PR interval, and a slurred QRS on the upstroke, yielding a widened QRS complex;
this morphology is referred to as a "Delta wave"]
A 22F c/o thick, white, "cottage-cheese" like vaginal discharge, pruritus, vulvar burning and dyspareunia.
The nurse suspects a diagnosis of: correct answers Candidiasis [characterized by pruritus & thick, white,
"cottage-cheese" like vaginal discharge]
Which atrioventricular block is characterized by a consistent but prolonged PR interval, and a consistent
R to R interval? correct answers First degree AV block [Second degree type I has progressive elongation
of PR interval; second degree type 2 has a consistent PR interval, but inconsistent R to R interval; third
degree heart block has a consistent R to R interval, but the P waves get lost]
Fever, bloating, and pain at the right costal margin upon palpation is associated with which disorder?
correct answers Cholecystitis [pain at the right costal margins = "Murphy's sign"]
JVD, increased CVP, hepatomegaly, and peripheral edema is seen in which disorder? correct answers
Right heart failure [S&S = JVD, increased right atrial pressure (CVP), peripheral edema, ascites,
hepatomegaly, and splenomegaly; left heart failure S&S = pulmonary edema]
