A nurse on a telemetry unit is caring for a client who has premature ventricular contractions (PVCs). While sitting in a chair, the client reports feeling lightheaded. If the client is having PVCs, which of the following findings should the nurse expect when auscultating the client's apical pulse?
Irregular pulsations
Bounding pulsations
Tachycardia
Bradycardia
The Correct Answer is A
A. Irregular pulsations are expected with PVCs because they cause occasional early beats that disrupt the regular rhythm of the pulse.
B. Bounding pulsations are not specific to PVCs and are more indicative of conditions like high cardiac output states.
C. Tachycardia is not a direct finding associated with PVCs; PVCs are more about irregular beats rather than a consistently high heart rate.
D. Bradycardia is not typically associated with PVCs; PVCs are characterized by irregular beats but not necessarily a slow heart rate.

Explanation
1. Provider Consult
Angina: Not typically associated with immediate provider consultation.
MI: Requires immediate consultation for treatment decisions, such as medication or interventions.
2. Client's Initial Report of Manifestations
Angina: Can present with discomfort or pressure that is transient and relieved by rest or nitroglycerin.
MI: Can present similarly but is often more severe and sustained; discomfort may be a precursor to a myocardial infarction.
3. Treadmill Stress Test
Angina: Often used to provoke symptoms under controlled conditions for diagnosis.
MI: Not used during an acute phase; rather, diagnostics are performed through EKG and cardiac enzyme tests.
4. Result of Nitroglycerin Therapy
Angina: Relief from nitroglycerin indicates angina.
MI: Nitroglycerin might not provide relief; other treatments and diagnostics are needed.
5. 12 Lead EKG Report
Angina: ST depression and T-wave inversion can occur with angina.
MI: These EKG changes can indicate ischemia, which could be part of an acute MI if accompanied by other severe symptoms or in the presence of persistent symptoms.
