Final answer:
The nurse should look for pulmonary congestion as an assessment finding in a client with systolic left-sided heart failure.
Step-by-step explanation:
Systolic left-sided heart failure occurs when the left ventricle of the heart is unable to pump sufficient blood into the systemic circulation, causing fluid to back up in the pulmonary capillaries of the lungs. As a result, the nurse should look for assessment finding of pulmonary congestion in this client. Pulmonary congestion refers to the accumulation of fluid in the air sacs of the lungs, which can lead to difficulty breathing and chest pain.
