EXAM PREP
A 65-year-old patient with a history of diabetes mellitus, CHF and
unstable angina is admitted to the unit following CABG x 3 and mitral
valve repair.
The patient is receiving infusions of propofol (Diprivan), epinephrine
(Adrenalin) and milrinone (Primacor). Data are:
HR 60
T 95 degrees F (35 degrees C)
MAP 65 mm Hg
CVP 10 mm Hg
PA 36/18 mm Hg Cl 2.1 L/min/m2
pH 7.30
PaCO2 40 mm Hg PaO2 140 mm Hg
HCO3 18 mEq/L
ABGs on 60% on the ventilator. The nurse is concerned the patient is at
increased risk for
A) ventricular dysrhythmias.
,B) right heart failure.
c) neurocognitive dysfunction.
D) respiratory complications.
A) ventricular dysrhythmias
The patient is at increased risk for ventricular dysrhythmias.
Hypothermia, acidosis, intracardiac monitoring (presence of PA
catheter) and underlying heart disease are risk factors for ventricular
dyshythmias. Reperfusion of zones of ischemia or infarction can trigger
ventricular dyshythmias and are more common in patients with prior Mis,
unstable angina and an EF of less than 40%.
Although right heart failure is not uncommon after mitral valve surgery, it
would be manifested by high CVP and low CO. Patients with preexisting
lung disease and smoking history are at increased risk for respiratory
complications. Risk factors for neurocognitive dysfunction include older
patients with preexisting
cerebrovascular disease or diabetes.
,Which hemodynamic profile is indicative of right heart failure?
A) CVP 20 mm Hg, PAOP 17 mm Hg, Cl 2.6 L/min/m2
B) CVP 4 mm Hg, PAOP 18 mm Hg, CI 2.3 L/min/m2
C) CVP 19 mm Hg, PAOP 10 mm Hg, Cl 2.1 L/min/m2
D) CVP 10 mm Hg, PAOP 12 mm Hg, CI 1.6 L/min/m2
C) CVP 19 mm Hg, PAOP 10 mm Hg, Cl 2.1 L/min/m2
RHF is characterized by elevated CVP, low CO & CI, and a decreased or
normal PAOP. Interventions should focus on optimizing preload.
, Heart block is MOST LIKELY to occur after which of the following
procedures?
A) bypass of the circumflex coronary artery
B) aortic valve replacement
C) the maze procedure
D) thoracic aneurysm repair
B) AVR
Heart block is a known complication of aortic valve replacement due to
anatomical position and potential trauma to the conduction system.
Unless the aortic valve is replaced with a thoracic aneurysm repair, it is
not associated with heart block. The circumflex artery supplies the
posterior wall of the left atrium
and left ventricle and is rarely associated with heart block while the
MAZE procedure is performed to interrupt electrical pathways that
cause atrial fibrillation.
