The nurse is teaching the client what to expect after coronary artery bypass graft (CABG) surgery. Which of the following client statements demonstrates that the client correctly understood the teaching?
"Pain medication is generally not needed after this surgery."
"I will be fed with a tube into my stomach until I can eat again."
"The nurses will be checking on me every four hours."
"I will be given a pen and paper to communicate because I will still have a breathing tube in my throat."
The Correct Answer is D
A. "Pain medication is generally not needed after this surgery.": CABG surgery involves a major thoracic incision and often sternal splitting, which can cause significant postoperative pain. Adequate pain management is essential to promote deep breathing, prevent atelectasis, and facilitate mobility, so this statement reflects a misunderstanding of postoperative care.
B. "I will be fed with a tube into my stomach until I can eat again.": Most CABG patients do not require prolonged enteral feeding postoperatively. Nutrition is typically restarted orally as tolerated once the patient is alert and able to swallow safely, making routine tube feeding uncommon unless complications occur.
C. "The nurses will be checking on me every four hours.": Postoperative CABG patients require frequent monitoring, often hourly or more initially, to assess vital signs, hemodynamic status, and signs of complications. Checking only every four hours would be inadequate and unsafe in the early postoperative period.
D. "I will be given a pen and paper to communicate because I will still have a breathing tube in my throat.": Immediately after surgery, patients are often intubated for mechanical ventilation and are unable to speak. Using alternative communication methods such as pen and paper allows the patient to express needs safely while intubated.

Correct Answer is B
Explanation
A. Slow repolarization of ventricular Purkinje fibers: Repolarization of the ventricular Purkinje fibers occurs later in the cardiac cycle and is not represented by the P wave. This process is reflected in other components of the ECG, primarily the T wave, which indicates ventricular repolarization.
B. Atrial depolarization: The P wave represents the depolarization of the atria, initiated by the sinoatrial (SA) node. It reflects the electrical impulse traveling through the atrial myocardium, which triggers atrial contraction and contributes to ventricular filling. Correct interpretation of the P wave helps assess atrial rhythm and detect abnormalities such as atrial enlargement.
C. Early ventricular repolarization: Early ventricular repolarization is part of the T wave phase and is unrelated to atrial activity. Misidentifying the P wave as representing ventricular repolarization would lead to errors in rhythm analysis and patient assessment.
D. Ventricular depolarization: Ventricular depolarization is reflected by the QRS complex, not the P wave. The QRS complex shows electrical conduction through the ventricles, triggering their contraction, and must be distinguished from atrial depolarization for accurate ECG interpretation.
Correct Answer is ["A","B"]
Explanation
A. is relieved by nitroglycerine: Stable angina is typically predictable and relieved by rest or sublingual nitroglycerin within minutes. The ability of nitroglycerin to quickly alleviate the pain suggests myocardial oxygen demand–supply mismatch without acute myocardial injury, distinguishing it from myocardial infarction pain, which is often persistent and unrelieved by nitroglycerin.
B. is precipitated by physical or emotional exertion: Pain that occurs with exertion or emotional stress is characteristic of stable angina. The predictable pattern and resolution with rest or medication reflect temporary myocardial ischemia rather than the prolonged ischemia and cellular injury seen in myocardial infarction.
C. does not radiate to the neck, back, or arms: Radiation of pain is not a reliable differentiator between stable angina and myocardial infarction. Stable angina can also radiate, and the absence of radiation does not confirm its presence or distinguish it from infarction.
D. is a sensation of tightness or squeezing: The quality of the pain alone cannot differentiate stable angina from myocardial infarction, as both can present with tightness, pressure, or squeezing sensations. Additional features like triggers, duration, and response to nitroglycerin are needed for differentiation.
