1. A patient is brought to the cardiac catheterization lab for an
emergent percutaneous coronary intervention (PCI) following an ST-
segment elevation myocardial infarction (STEMI). Which
medication should the RN anticipate administering to prevent
thrombus propagation during the procedure?
A. Adenosine
B. Heparin
C. Nitroglycerin
D. Amiodarone
CORRECT ANSWER: B
,Rationale: Heparin is the standard anticoagulant used during PCI to
prevent thrombus formation on catheters and guidewires and to
prevent further thrombosis at the site of the arterial lesion.
Adenosine is used for diagnostic purposes or to treat supraventricular
tachycardia. Nitroglycerin is a vasodilator used for chest pain and
coronary spasm. Amiodarone is an antiarrhythmic.
2. During a left heart catheterization, the pressure waveform in the
left ventricle shows an elevated end-diastolic pressure (LVEDP) of 28
mmHg. This finding is most indicative of which condition?
A. Aortic stenosis
B. Mitral stenosis
C. Left ventricular failure
D. Pericardial constriction
CORRECT ANSWER: C
Rationale: An elevated LVEDP reflects increased pressure in the left
ventricle at the end of diastole, which is a hallmark of left ventricular
failure or volume overload. Aortic stenosis is characterized by a high
pressure gradient across the aortic valve during systole. Mitral
stenosis results in an elevated left atrial pressure. Pericardial
,constriction typically shows equalization of diastolic pressures in all
four chambers.
3. The RN is monitoring a patient post-cardiac catheterization via
the right femoral artery. Which assessment finding is the highest
priority and requires immediate intervention?
A. A 2 cm hematoma at the insertion site
B. Patient reports a pain score of 4/10 in the right groin
C. The right foot is cool to the touch with a weak dorsalis pedis
pulse
D. Small amount of serous drainage at the puncture site
CORRECT ANSWER: C
Rationale: A cool foot with a weak pulse indicates acute limb
ischemia, which is a critical complication that could lead to tissue
loss. This requires immediate assessment and intervention. A small
hematoma, mild pain, and serous drainage are common post-
procedure findings that warrant monitoring but are not as urgent as
signs of arterial occlusion.
, 4. While preparing for a right heart catheterization, the RN is setting
up the pressure transducers. The transducer must be leveled to which
anatomical landmark to ensure accurate pressure readings?
A. The sternal angle (Angle of Louis)
B. The mid-axillary line at the fourth intercostal space
C. The manubrium
D. The xiphoid process
CORRECT ANSWER: B
Rationale: The transducer must be leveled at the mid-axillary line at
the fourth intercostal space, which corresponds to the level of the
right atrium (the phlebostatic axis). This ensures accurate
measurement of central venous pressure and pulmonary artery
pressures. The sternal angle, manubrium, and xiphoid process are
not the standard reference points for this purpose.
5. A patient who underwent PCI with a drug-eluting stent (DES) is
being discharged. The RN reinforces the importance of dual
antiplatelet therapy (DAPT). What is the minimum recommended
duration of DAPT for this patient?
A. 1 month
