Decreased Cardiac Output is a critical nursing diagnosis that describes a state where the heart's ability to pump sufficient blood to meet the body's metabolic needs is compromised. This condition is commonly seen in patients with heart failure, myocardial infarction, or cardiomyopathy, and it presents with symptoms like fatigue, dyspnea on exertion, and crackles in lung bases. Understanding this diagnosis is essential for nursing students preparing for the NCLEX, as it involves recognizing subtle changes in patient condition and implementing timely interventions to prevent complications such as pulmonary congestion and systemic hypoperfusion.
Definition & Related Factors
Decreased Cardiac Output is defined by NANDA as the inadequate blood volume pumped by the heart to meet the body's metabolic demands. It can be related to altered contractility, which affects the heart's ability to contract effectively. Risk factors include heart failure, myocardial infarction, valvular heart diseases, and cardiomyopathy. These conditions can impede the heart's pumping ability through structural or functional cardiac changes.
Assessment Findings
When assessing a patient with suspected Decreased Cardiac Output, nurses should gather both subjective and objective data. Subjectively, patients may report fatigue and dyspnea on exertion due to inadequate tissue perfusion. Objectively, nurses should assess for elevated heart rate, reduced blood pressure, and the presence of crackles in lung bases, which indicate pulmonary congestion. Additionally, peripheral edema and cool, clammy skin may be present due to reduced cardiac output and poor peripheral circulation.
Expected Outcomes & Goals
The primary goal for patients with Decreased Cardiac Output is to improve cardiac function and ensure adequate tissue perfusion. Expected outcomes include the patient reporting reduced fatigue and dyspnea, improved breath sounds without crackles, stable vital signs within the patient's baseline, and increased activity tolerance. These outcomes are achieved by addressing the underlying cause and providing supportive care.
Key Nursing Interventions
Nursing interventions include monitoring vital signs and oxygen saturation frequently to detect early signs of deterioration. Administering prescribed cardiac medications, such as ACE inhibitors or beta-blockers, can improve cardiac contractility and output. Elevating the head of the bed can facilitate breathing by reducing venous return and pulmonary congestion. Educating the patient on energy conservation techniques helps manage fatigue, and encouraging adherence to a low-sodium diet can prevent fluid overload.
NCLEX Tips
On the NCLEX, questions about Decreased Cardiac Output often focus on recognizing clinical signs and implementing appropriate interventions. Key points include understanding the pathophysiology of heart failure, recognizing early signs of decreased perfusion, and prioritizing interventions that enhance cardiac output, such as medication administration and patient positioning. Remember, safety and monitoring for complications like pulmonary edema are crucial.
Practice NCLEX Question
A patient with heart failure is experiencing increased fatigue and crackles in the lung bases. What is the priority nursing diagnosis?
A. Decreased Cardiac Output
B. Ineffective Airway Clearance
C. Activity Intolerance
D. Impaired Gas Exchange
Show Answer & Rationale
Correct Answer: A
The patient's symptoms indicate an inadequate cardiac output affecting perfusion, making 'Decreased Cardiac Output' the priority diagnosis.
