Key Terms/Concepts
Left-Sided Heart Failure: A condition where the left
ventricle cannot pump effectively, leading to fluid
accumulation in the lungs, causing symptoms like orthopnea.
Right-Sided Heart Failure: A condition where the right
ventricle fails to pump blood effectively, leading to fluid
buildup in the body, often resulting in edema.
Spironolactone: A potassium-sparing diuretic used to treat
heart failure, which can lead to elevated potassium levels.
Enalapril: An ACE inhibitor used to treat heart failure, which
can cause side effects like orthostatic hypotension.
Symptoms
Orthopnea: Difficulty breathing when lying flat, commonly
associated with left-sided heart failure.
Sacrum Edema: Swelling in the sacral area, indicative of
right-sided heart failure.
Interventions
Sodium Intake Management: Maintain the client's sodium
intake at 3 gm daily to help manage fluid retention in heart
failure patients.

Key Adverse Effects
Orthostatic Hypotension: A drop in blood pressure upon
standing, which can occur as an adverse effect of enalapril.
Facts to Memorize

Overview of Heart Failure
Definition and Types of Heart Failure
Heart failure is a clinical syndrome characterized by
the heart's inability to pump sufficient blood to meet
the body's needs.
It can be classified into two main types: left-sided
heart failure and right-sided heart failure, each with
distinct symptoms and causes.
Pathophysiology of Heart Failure
In left-sided heart failure, the left ventricle fails to
effectively pump blood to the body, leading to
pulmonary congestion.
