Record intake and output. If patient is acutely ill, measure hourly urine
output and note decreases in output.
- Rationale: Reduced cardiac output results in reduced perfusion of the
kidneys, with a resulting decrease in urine output.
For patients with increased preload, limit fluids and sodium as ordered.
- Rationale: Fluid restriction decreases extracellular fluid volume and
reduces demands on the heart.
Closely monitor fluid intake including IV lines. Maintain fluid restriction if
ordered.
- Rationale: In patients with decreased cardiac output, poorly functioning
ventricles may not tolerate increased fluid volumes.
Auscultate heart sounds; note rate, rhythm, presence of S3, S4, and lung
sounds.
- Rationale: The new onset of a gallop rhythm, tachycardia, and fine
crackles in lung bases can indicate onset of heart failure. If patient
develops pulmonary edema, there will be coarse crackles on inspiration
and severe dyspnea.
Closely monitor for symptoms of heart failure and decreased cardiac
output, including diminished quality of peripheral pulses, cold and
clammy skin and extremities, increased respiratory rate, presence of
paroxysmal nocturnal dyspnea or orthopnea, increased heart rate, neck
vein distention, decreased level of consciousness, and presence of edema.
- Rationale: As these symptoms of heart failure progress, cardiac output
declines.
Note chest pain. Identify location, radiation, severity, quality, duration,
associated manifestations such as nausea, and precipitating and relieving
factors.
- Rationale: Chest pain/discomfort is generally suggestive of an inadequate
blood supply to the heart, which can compromise cardiac output. Patients
with heart failure can continue to have chest pain with angina or can re-
infect.
If chest pain is present, have patient lie down, monitor cardiac rhythm,
give oxygen, run a strip, medicate for pain, and notify the physician.
- Rationale: These actions can increase oxygen delivery to the coronary
arteries and improve patient prognosis.
