RCIS(question with complete
solution )already passed 2023
Hypaque contrast material is _______ and when injected into the heart causes an immediate _____ in
cardiac output.
a. Hypertonic, Increase
b. Hypertonic, Decrease
c. Hypotonic, Increase
d. Hypotonic, Decrease - correct answer b. Hypertonic, Decrease
What chemical element in contrast material makes it radiopaque to X-rays?
a. Calcium
b. Iodine
c. Barium
d. Lead - correct answer b. Iodine
Older angiographic contrast agents such as Hypaque or Renografin commonly overload the blood
volume of a patient in CHF. New contrast agents such as Ioxaglate (Hexabrix) and Iohexol (Omnipaque)
do not increase the preload as much because of their: a. Low osmolarity
b. Low Na+ and K+ content
c. Higher radio-opacity per cc
d. Increased ionization in solution - correct answer a. Low osmolarity
A patient's LV angiogram shows apical hypokinesis during sinus rhythm. But following one PVC the
compensatory beat shows significantly improved EF. This post-"PVC potentiation" of LV contractility
probably indicates:
a. Reversible apical ischemia
b. Irreversible apical infarcted area
c. Recent LAD occlusion

Higher radio-opacity per cc d. Increased ionization in solution - correct answer a. Low osmolarity A patient's LV angiogram shows apical hypokinesis during sinus rhythm. But following one PVC the compensatory beat shows significantly improved EF. This post-"PVC potentiation" of LV contractility probably indicates: a. Reversible apical ischemia b. Irreversible apical infarcted area c. Recent LAD occlusion

d. Old LAD occlusion - correct answer a. Reversible apical ischemia The cutoff between normal and abnormal LV function is considered to be an EF of: a. 10% b. 30% c. 50% d. 70% - correct answer c. 50% Following LV-angiography, this LV-AO pullback pressure was recorded on X200. What abnormality is indicated? a. None, this is normal pressure amplification in periphery b. Aortic stenosis c. Coarctation of Aorta d. Idiopathic Hypertrophic Subvalvular Stenosis - correct answer a. None, this is normal pressure amplification in periphery Aneurysmal LV walls which bulge in systole are termed: a. Akinetic b. Asyneresis c. Dyskinetic d. Hypokinetic - correct answer c. Dyskinetic You are assisting a new cardiologist do a right heart cath on a cyanotic child. Before inflating the balloon he asks you "What should I use to inflate this balloon?" You should answer______. a. Air b. CO c. Sterile Saline d. 50%-50%, contrast and saline - correct answer b. CO Which statement regarding the set-up of hemodynamic monitoring equipment is most correct?

All of the following statements regarding PA catheter insertion are true EXCEPT: a. Following vessel puncture, SaO2 analysis of a withdrawn blood sample should be <95% b. Use a Paceport Swan in patients with LBBB c. The major risk of internal jugular cannulation is carotid artery puncture d. Air embolism is of concern at the time of guidewire and catheter insertion - correct answer a. Following vessel puncture, SaO2 analysis of a withdrawn blood sample should be <95% To help prevent pulmonary artery rupture when wedging a Swan-Ganz catheter: a. Check the pulmonary artery occlusion pressure frequently b. Withdraw PAC slightly if a PAOP waveform is obtained with inflation of <1.25 ml air c. Advance PAC slightly if a PAOP waveform is obtained with inflation of <1.25 ml air d. Always use 1.5 ml air to inflate the balloon for a PAOP - correct answer b. Withdraw PAC slightly if a PAOP waveform is obtained with inflation of <1.25 ml air Which statement regarding thrombus formation on Swan-Ganz catheters ismost correct? a. All intravascular monitoring catheters are thrombogenic b. Heparin should be added to the IV solutions of all patients with a PA catheter c. Catheters occluded by thrombus should be flushed vigorously with saline to clear the catheter d. Thrombus begins to form on catheters only after 3 to 5 days in the vessel - correct answer a. All intravascular monitoring catheters are thrombogenic Which one of the following statements about abnormal central venous O2 saturation (SvO2) is most correct? a. SvO2 values <0.60 indicate threatened tissue oxygenation b. SvO2 values >0.80 indicate adequate or increased tissue oxygenation c. SvO2 values <0.60 indicate low oxygen consumption d. SvO2 values >0.80 indicate increased oxygen consumption - correct answer a. SvO2 values <0. indicate threatened tissue oxygenation Central venous pressure (CVP) can directly assess which 2 of the following?

  1. RV function
  2. LV function
  3. Fluid volume status
  4. Myocardial contractility a. 1 & 2 b. 2 & 3 c. 3 & 4 d. 1 & 3 e. 2 & 4 - correct answer d. 1 & 3 Which of the following is most likely to be associated with hypovolemia? a. Increased central venous pressure b. Decreased RV end-diastolic pressure c. Increased PA occlusion pressure d. Decreased heart rate - correct answer b. Decreased RV end-diastolic pressure Which one of the following statements about the pulmonary artery occlusion pressure (wedge) is most correct? a. The pulmonary artery occlusion pressure is measured through the most proximal catheter port b. Inflation of the balloon momentarily stops the flow of blood and creates a static column of blood between the tip of the catheter and the left atrium c. The PAOP waveform always contains 3 positive waves (a, c, v) d. During inflation of the balloon the pulmonary artery pressure changes to a right ventricular waveform
  • correct answer b. Inflation of the balloon momentarily stops the flow of blood and creates a static column of blood between the tip of the catheter and the left atrium Which one of the following statements about hemodynamic waveforms is most correct? a.
