Rationale: Most ventricular filling (~70-80%) occurs passively during atrial diastole (B) when AV valves are open.
Question 2 of 5
A client has been taking warfarin sodium (Coumadin) for the prevention of deep vein thrombosis. When the home care nurse arrives for a weekly visit, the client reports having been using aspirin (acetylsalicylic acid) daily for arthritic pain since hearing a commercial on television bolstering its benefits. Which of the following is the most appropriate response by the nurse, based on an understanding of the effect of combining Coumadin with aspirin?

Question 3 of 5

Question 4 of 5
The Nurse understands that a pulmonary embolism is a most unlikely complication in the postoperative period following?
Correct Answer: A
Rationale: Pulmonary embolism (PE) is a risk after surgeries with prolonged immobility or venous manipulation (e.g., prostatectomy, hysterectomy, vein ligation), but appendectomy typically involves less risk due to shorter duration and minimal venous disruption.
Question 5 of 5
Which clinical feature found on assessment should indicate to a nurse that a client has congestive heart failure?
Correct Answer: C
Rationale: Congestive heart failure (CHF) causes fluid backup, leading to liver tenderness (hepatomegaly from right heart failure) and peripheral edema (fluid retention). Pulmonary crackles indicate left heart failure, but liver tenderness is more specific to right-sided CHF.
