Upon admission to the ICU, a patient with a history of cor pulmonale will likely be exhibiting which of the following clinical manifestations of right heart failure? Select all that apply.

A)
Fine crackles throughout both lung fields
B)
+4 pitting edema in lower extremities
C)
Expectorating copious amounts of frothy, pink sputum
D)
Jugular vein distension
E)
Altered level of consciousness

Question 2

A 70-year-old woman with ongoing severe atrial fibrillation is scheduled for defibrillation. What is an aspect of the rationale and physiology of defibrillation treatment?

A)
Interruption of disorganized impulses by the current allows the AV node to readopt its normal pacemaker role.
B)
Defibrillation can be achieved using either a transcutaneous or transvenous pacemaker.
C)
Defibrillation must be coincided with the R wave of the ECG in order to be successful.
D)
The goal is to depolarize the entire heart during the passage of current.

Answer to Question 1

Ans:
B, D, E

Feedback:

Signs of right-sided HF include venous congestion (jugular vein distension), peripheral edema (+4 pitting edema in feet), shortness of breath, and productive cough. Altered level of consciousness may occur as the result of carbon dioxide retention. Fine crackles in all lung fields and frothy, pink sputum are common in left-sided HF.

Answer to Question 2

Ans:
D

Feedback:

The benefits of defibrillation are achieved by depolarizing the heart during the passage of current, allowing the SA node to regain control. It is not achieved by the use of a pacemaker, and cardioversion, not defibrillation, is coincided with the R wave.
