CCRN questions Hemodynamics
Cardiogenic shock secondary to left ventricular failure will commonly result in:
A) Decreased afterload
B) Narrow Pulse Pressure
C) Decreased Preload
D) Widening Pulse Pressure - ANS-B) Narrow pulse pressure
Early hypoxemia normally effects in which of the following?
A) Respiratory Alkalosis
B) Metabolic Acidosis
C) Respiratory Acidosis
D) Metabolic Alkalosis - ANS-A) Respiratory Alkalosis
When the PaO2 starts offevolved to lower, the decrease is sensed by means of sensors in
the aortic arch and carotid our bodies; as a compensatory mechanism for the lower in PaO2,
there's an increase within the fee of air flow. This elevated charge of air flow outcomes inside
the "blowing off" of PaCO2 in addition to a respiration alkalosis. Prolonged, severe
hypoxemia will bring about anaerobic metabolism and a metabolic acidosis.
One effect of a dobutamine (Dobutrex) infusion includes:
A) A decrease in HR
B) An growth in Afterload
C) A decrease in contractility
D) An increase in myocardial oxygen call for - ANS-D) An increase in myocardial oxygen call
for
Dobutamine stimulates beta I receptors inside the coronary heart and will increase
contractility. This stimulation, while helpful for reduced contractility, additionally effects in an
increase in myocardial oxygen call for and work (and viable arrhythmias).
One hemodynamic advantage of intra-aortic balloon remedy is:
A) Balloon inflation prevents right to left shunt
B) Balloon deflation will increase coronary artery perfusion
C) Balloon inflation optimizes aortic valve performance
D) Balloon deflation decreases left ventricular afterload - ANS-D) Balloon deflation
decreases left ventricular afterload
Pulmonary high blood pressure may also bring about which of the subsequent?
A) Left HF
B) Right HF
C) Increased lung compliance
D) Arterial hypertension - ANS-B) Right HF
Short episodes of non-sustained torsade de pointes ventricular tachycardia are visible at the
cardiac display. The nurse must anticipate orders for which of the following infusions for this
patient?
A) Amiodarone
B) Magnesium
, C) Digoxin
D) Potassium - ANS-B) magnesium
Torsade de pointes VT is due to extended QT c program languageperiod, and magnesium is
indicated for this problem. Amiodarone may also worsen the trouble via in addition
prolonging the QT c program languageperiod. The closing picks are not powerful treatments
for torsade de pointes.
The 75-year-antique patient develops frequent 6 to ten 2nd episodes of asystole,
interspersed with ordinary sinus rhythm this is associated with hypotension. The priority
intervention is:
A) Transcutaneous pacing
B) Fluid bolus
C) Transvenous pacing
D) Vasopressors - ANS-A) Transcutaneous pacing
The nurse wishes to assess adequacy of the tubing/catheter machine for the arterial line.
Which of the subsequent interventions will quality verify this?
A) Use heparinized flush
B) Level the transducer
C) Zero balance the transducer
D) Perform a square wave check - ANS-D) Perform a rectangular wave test
Use of heparin, preference (A), can be used to preserve catheter patency, however is now
seldom applied; leveling of the transducer, preference (B), is used to make sure accuracy of
the pressures acquired; zeroing the transducer, desire (C), removes the consequences of
atmospheric stress at the physiologic stress.
The affected person has a blood strain of 78/forty, proper atrial (RA) stress of 1 mmHg,
pulmonary artery occlusive pressure (PAOP) of 4 mmHg, systemic vascular resistance
(SVR) 1800 and cardiac output (CO) of 3 L/min. Which of the subsequent is accurate
regarding this patient?
A) The affected person has septic shock; offer vasopressors
B) The affected person has cardiogenic surprise; offer high-quality inotropes
C) The patietn has hypovolemic surprise; offer fluid resuscitation
D) The affected person has right ventricular infarct; offer fluids - ANS-C) The patietn has
hypovolemic surprise; provide fluid resuscitation
The hemodynamic profile defined is that of hypovolemic surprise. The SVR could not be
accelerated in septic surprise, (A); the PAOP would not be reduced, and the CO could be
decrease in cardiogenic surprise, (B); the RA strain could no longer be low in RV infarct, (D).
The patient has a blood stress of 78/40, proper atrial (RA) strain of 13 mmHg, pulmonary
artery occlusive stress (PAOP) of 5 mmHg, systemic vascular resistance (SVR) 1900
dynes/sec/cm5 and cardiac output (CO) of one.9 L/min. Which of the following is correct
regarding this affected person?
A) The patient has septic surprise; offer vasopressors
B) The patient has cardiogenic shock; provide effective inotropes
C) The patient has hypovolemic surprise; offer fluid resuscitation
