QUESTION 1 OF 193
The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent
deployment, For optimal care of the patient, the nurse should:
Correct Answer: Continuously monitor the patient in lead II
It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal
during the acute occlusion.
Rationale: Continuous monitoring of the patient in lead II is indicated following an inferior wall myocardial
infarction (MI) and stent deployment because lead II is typically the most sensitive lead for detecting inferior wall
changes. This specific monitoring strategy allows for early identification of any residual ischemia, arrhythmias, or
complications such as reocclusion or stent thrombosis. Therefore, by observing the lead most reflective of the affected
area, the nurse can promptly intervene to ensure optimal patient care post-percutaneous coronary intervention (PCI).
This aligns with It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal
during the acute occlusion. and Continuously monitor the patient in lead II.
QUESTION 2 OF 193
The ECG demonstrates ST elevation in leads II, III and aVF. The nurse needs to monitor
the patient closely for which of the following?
Correct Answer: Complication likely to occur after an acute inferior wall MI include bradycardia
secondary to ischemia to the SA and/or AV node, and papillary muscle rupture or dysfunction due to the
anatomical distance between the RCA and the papillary muscle.
Rationale: ST elevation in leads II, III, and aVF indicates an acute inferior wall myocardial infarction (MI), which
commonly involves the right coronary artery (RCA). Ischemia to the SA and AV nodes, which are often supplied by the
RCA, can lead to bradycardia and other conduction abnormalities. Additionally, the inferior wall's proximity to the
papillary muscles makes them susceptible to ischemia and subsequent rupture or dysfunction, leading to acute mitral
regurgitation. This aligns with Complication likely to occur after an acute inferior wall MI include bradycardia
secondary to ischemia to the SA and/or AV node, and papillary muscle rupture or dysfunction due to the anatomical
distance between the RCA and the papillary muscle. and and/or.
QUESTION 3 OF 193
The patient with diastolic heart develops SVT, heart rate 220/min. The most dangerous
hemodynamic effect is a decrease in:
Correct Answer: coronary artery perfusion.
Diastolic heart failure results in a problem with left ventricular FILLING secondary to ventricular thickening,
and contractility and ejection are maintained in diastolic failure. The rapid heart rate will decrease filling
time, worsen left ventricular filling and because coronary artery perfusion occurs during diastole, this
arrhythmia may be life-threatening.

, QUESTION 4 OF 193
The patient is receiving heparin infusion for the treatment of pulmonary embolism.
There has been a 60% decrease in the platelet count and no clinical change. Which of
the following is indicated?
Correct Answer: Discontinue heparin and being argatroban.
The patient most likely has HIT. Exposure to heparin needs to discontinued and a direct thrombin inhibitor
started for continued anticoagulation.
Rationale: A significant decrease in platelet count (typically >50% or absolute <150,000/µL) in a patient receiving
heparin, even without clinical thrombosis, is highly suggestive of heparin-induced thrombocytopenia (HIT). HIT is an
immune-mediated adverse drug reaction that paradoxically increases thrombotic risk and necessitates immediate
cessation of all heparin products. Argatroban is a direct thrombin inhibitor that is a recommended alternative
anticoagulant in patients with confirmed or suspected HIT, as it does not cross-react with the antibodies implicated in
this condition. This aligns with The patient most likely has HIT. Exposure to heparin needs to discontinued and a direct
thrombin inhibitor started for continued anticoagulation. and Discontinue heparin and being argatroban..
QUESTION 5 OF 193
The postoperative thoracic surgery patient has bubbling in the water seal drainage
chamber of the chest tube. Which of the following interventions is indicated?
Correct Answer: avoid high airway pressures
Bubbling in the water seal chamber is due to a pleural air leak, and high airway pressure will either prevent
resolution of the current air leak or make it worse.
Rationale: Bubbling in the water seal chest tube drainage chamber indicates an air leak from the pleural space.
Maintaining low airway pressures is crucial to promote the natural sealing of this leak. High airway pressures can
exacerbate the air leak or hinder its resolution by forcing more air into the pleural space. This aligns with and high
airway pressure will either prevent resolution of the current air leak or make it worse., Bubbling in the water seal
chamber is due to a pleural air leak and avoid high airway pressures.
QUESTION 6 OF 193
Which clinical sign might patients with both systolic and diastolic heart failure have in
common?
Correct Answer: Lung crackles
Both a problem with systolic (ejection problem) and diastolic (filling problem) will increase left heart
pressure and cause cardiogenic pulmonary edema (lung crackles).
Rationale: Both systolic dysfunction (impaired ejection) and diastolic dysfunction (impaired filling) lead to elevated
left ventricular pressures. This increased left ventricular pressure backs up into the pulmonary circulation, causing
pulmonary venous congestion and the characteristic finding of lung crackles due to fluid transudation into the alveoli.
Therefore, lung crackles are a common clinical sign in patients experiencing either or both types of heart failure. This
aligns with Both a problem with systolic (ejection problem) and diastolic (filling problem) will increase left heart
pressure and cause cardiogenic pulmonary edema (lung crackles). and Lung crackles.
