Discharge teaching for the client following biologic valve replacement includes explaining
to be cautious when going through metal detectors, or scanners at airports.
the need to take prophylactic anticoagulant before visiting the dentist.
signs and symptoms of papillary muscle rupture.
the need to take anticoagulants for three to six months post-operatively.
The Correct Answer is D
A. Biologic valves do not contain metal, so clients generally do not need special precautions when passing through metal detectors.
B. Routine prophylactic anticoagulation is not required for dental procedures with biologic valves; prophylactic antibiotics may be needed depending on the situation.
C. Papillary muscle rupture is a rare, acute complication of myocardial infarction, not a routine concern after biologic valve replacement.
D. Clients with biologic valve replacements typically require short-term anticoagulation for three to six months post-operatively to prevent thromboembolic events, making this the most important discharge teaching point.

Correct Answer is B
Explanation
A. A loud systolic murmur is expected in mitral regurgitation and does not require immediate notification unless there is a sudden change.
B. Increasing crackles indicate pulmonary congestion and worsening left-sided heart failure, which is an acute change requiring immediate intervention.
C. A palpable thrill is a chronic finding in severe regurgitation and is not an acute emergency.
D. Peripheral edema develops gradually and is important to note, but crackles signal more urgent pulmonary compromise.
Correct Answer is D
Explanation
A. The vertical spike seen on the ECG represents the pacemaker's electrical stimulus, but capture specifically refers to the heart’s response—not just the spike itself.
B. Failure to capture occurs when the pacemaker delivers a stimulus without causing depolarization, but this is the opposite of capture.
C. The pacemaker rate is the pacing rate, not capture. While it is often set above the intrinsic rate, this does not define capture.
D. Capture occurs when the pacemaker’s electrical stimulus successfully depolarizes the myocardium, producing a corresponding P wave (atrial pacing) or QRS complex (ventricular pacing) on the ECG. Effective capture confirms the pacemaker is working and coordinating appropriately with the heart’s electrical system.
