The nurse is caring for a patient with hypovolemic shock. The nurse should realize that this patient's heart sounds will change in which way?
1. diminished S2
2. accentuated S2
3. diminished S1 and S2
4. no change in S1 or S2
Correct Answer: 1
The S2 sound diminishes due to a fall in blood pressure. An accentuated S2 may be heard with HTN, exercise, excitement, and conditions of pulmonary HTN such as CHF and cor pulmonale. S1 diminishes with first-degree heart block, mitral regurgitation, CHF, CAD, and pulmonary or systemic HTN. The nurse should expect a change in the S2 sound.
