The nurse knows which of the following are correct physiologicadaptation to reduced cardiac output? Select all that apply.
Natriuretic peptides - In response to stretching of the atriaand dilation of the ventricles, the heart releases two natriureticpeptides: atrial natriuretic peptide (ANP) and B-natriureticpeptide (BNP).
Decreased venous tone – depletion of venous tone decreasesvenous pressure and thereby increases ventricular filling. Becauseof Starling's mechanism, decreased filling decreases strokevolume.
Cardiac dilation - results from a combination of increasedvenous pressure (see the following text) and reduced contractileforce.
Decreased heart rate - deceleration of heart rate increasescardiac output, thereby helping improve tissue perfusion.
Decreased contractility - decreased myocardial contractility hasthe obvious benefit of increasing cardiac output.
