What is a cause of fatigue when it is suspected to be an early symptom of heart failure? Show
1. Impaired renal perfusion 3. Decreased oxygenation of the tissues Fatigue is caused by decreased oxygenation of the tissues. Impaired renal perfusion resulting in decreased urine output during the day is a cause of nocturia, not fatigue. Paroxymal nocturnal dyspnea is caused by the reabsorption of fluids from the dependent body areas when the patient is lying flat. Dyspnea, not fatigue, is caused by an increased pulmunary pressure secondary to interstitial and alveolar edema. A nurse is caring for a patient diagnosed with heart failure who experiences fatigue. What could be the reason for fatigue? 1. Increased cardiac output 2. Impaired perfusion to vital organs Fatigue is one of the early signs of heart failure. Due to heart failure, there is inadequate blood circulation, leading to decreased perfusion to the vital organs. An impaired functioning of the vital organs may lead to fatigue. Cardiac output decreases in heart failure, depriving the body tissues of oxygen and nutrients, leading to fatigue. Inadequate blood supply results in inadequate oxygenation of the tissue and causes fatigue when the oxygen demands are not met. Hemoglobin levels are low in heart failure, leading to anemia. A decreased oxygen-carrying capacity of the blood also results in fatigue. A patient with chronic heart failure reports disturbed sleep due to the urge to urinate frequently. What is the most likely cause of this patient's nocturia? 1. Diabetes is commonly found in patients with CHF and frequently causes nocturia 4. Peripheral interstitial fluid enters circulation at night, increasing kidney function and causing nocturia In a patient with chronic heart failure, there is decreased renal perfusion and urine production during the day, because most fluid gets accumulated in the peripheral tissues. However, while lying down at night in a recumbent position, the fluid from the peripheral interstitial tissues enters the central circulation. This leads to an increase in renal function, causing nocturia. Diabetes, an enlarged prostate, and caffeine intake before going to bed also cause nocturia but are less likely in this case. A patient with chronic heart failure reports fatigue. The nurse assesses that the patient's respiratory rate is 26 breaths/minute. Which nursing action will promote ventilation in the patient? 1. Using pulse oximetry 2. Providing oxygen therapy Oxygen therapy helps improve oxygen saturation and meets the tissue oxygen needs, which may relieve dyspnea and fatigue. Pulse oximetry helps monitor the effectiveness of oxygen therapy but does not directly promote ventilation. Biventricular pacing helps modulate the electrical system of the heart; it does not promote ventilation. Taking physical and emotional rest helps in conserving energy; it does not promote ventilation. A patient has left ventricular hypertrophy from untreated hypertension. For what condition should the nurse monitor in the patient? 1. Bradycardia 2. Poor contractility Poor contractility is a complication seen in patients who have hypertrophy of the cardiac walls. The heart muscle, which undergoes hypertrophy increases in muscle mass and cardiac wall thickness, due to overwork and strain. As a result, the hypertrophic heart muscle exhibits poor contractility over time. Bradycardia is not a complication that would result from cardiac hypertrophy. A hypertrophic heart requires more oxygen (O2) to perform work. Because the tissue in a hypertrophic heart becomes ischemic more easily, there is poor coronary artery circulation. The nurse notices that a patient with pulmonary edema experiences shortness of breath while lying down. What is the most likely reason for the development of orthopnea in this patient? 1. Heart failure 4. Pulmonary congestion In pulmonary edema, there is congestion in the lungs, which causes inadequate oxygenation. In a recumbent position, the congestion is further increased, causing further hypoxemia, which causes orthopnea, or shortness of breath while lying down. Orthopnea does not indicate heart failure but is an early sign of heart failure. Hypertension and pulmonary failure are found in later stages of heart failure. The nurse is educating a patient with diastolic failure. What explanation would be most appropriate for the patient to understand as a characteristic feature of this disorder? 1. Inability to fill
blood 1. Inability to fill blood Diastolic failure is the inability to relax and fill the ventricles during diastole. Systolic failure is the inability to pump blood. Mixed systolic and diastolic failure is the inability of the heart to pump and fill the blood. Decrease in ejection fraction is a characteristic feature of systolic failure. The nurse is caring for a patient with left-sided heart failure. For what complications of this disorder should the nurse carefully monitor? 1. Hepatomegaly 4. Pulmonary congestion The most common form of heart failure is left-sided heart failure. It results from left ventricular dysfunction. This prevents normal, forward blood flow and causes blood to back up into the left atrium and pulmonary veins. There would be fluid leakage from the pulmonary capillary bed into the interstitium and then the alveoli; this manifests as pulmonary congestion and edema. Right-sided heart failure occurs when the right ventricle fails to contract effectively. The nurse is assessing a patient with a diagnosis of left-sided heart failure (HF). What symptom does the nurse observe as occurring exclusively with this disorder? 1. Fatigue 4. Frothy, pink-tinged sputum Frothy, pink-tinged sputum is a characteristic symptom associated with left-sided HF. Fatigue and anxiety are present as a common symptom both in right-sided and left-sided HF. Anorexia is exclusively a symptom of right-sided HF. The nurse is educating the patient with mild heart failure (HF) about lifestyle changes in order to avoid complications and readmission. Which statement made by the patient indicates to the nurse that further education is required? The nurse is educating the patient with mild heart failure (HF) about lifestyle changes in order to avoid complications and readmission. Which statement made by the patient indicates to the nurse that further education is required? 1. "I shouldn't exercise or do anything to strain my heart." 3. "I can add salt to my food and eat what I want." Not following a low-sodium diet may lead to complications such as hypertension, edema, and other conditions. Fluid restriction is not usually prescribed for the patient with mild to moderate HF. However, in chronic HF, fluids are limited to 2 L/day. Use of ice pops and hard candy helps avoid thirst, which is a side effect of the HF medications. Lack of exercise does not increase a patient's sodium level. The nurse is caring for a patient who has been diagnosed with paroxysmal nocturnal dyspnea. Which complaint would the nurse expect this patient to report? 1. Breathlessness on exertion 3. Awakening from sleep with feelings of suffocation Paroxysmal nocturnal dyspnea occurs when the patient is asleep. The patient awakes in a state of panic with a feeling of suffocation and has a strong desire to sit or stand up. Breathlessness on exertion is called dyspnea. Shortness of breath when lying down, that is, orthopnea, often accompanies dyspnea. A decreased attention span is a behavioral change that may be due to poor gas exchange or worsening heart failure. The nurse is administering medication to a patient with pulmonary edema. What medication administered to the patient would have the best outcome? 1. Diuretics 1. Diuretics Diuretics are used to treat pulmonary edema, because they act on the ascending loop of Henle to promote sodium, chloride, and water excretion. Vasodilators cause dilation of the blood vessel wall. β-adrenergicblockers help counteract the negative effect of the sympathetic nervous system. Angiotensin-converting enzyme inhibitors block the enzyme that can cause angiotensin I to form angiotensin II, which is a potent vasoconstrictor. Which cause of fatigue is associated with heart failure?Exercise intolerance and fatigue are often the most common symptoms of heart failure. This tiredness or fatigue occurs because less blood reaches the muscles and tissues, due to the reducing pumping ability of the heart.
Which items in a patient's medical history are risk factors for heart failure HF )?Heart or blood vessel conditions, serious lung disease, or infections such as HIV or SARS-CoV-2 raise your risk. This is also true for long-term health conditions such as obesity, high blood pressure, diabetes, sleep apnea, chronic kidney disease, anemia, thyroid disease, or iron overload.
Which patient conditions increase the risk of developing heart failure?The most common conditions that can lead to heart failure are coronary artery disease, high blood pressure and previous heart attack. If you've been diagnosed with one of these conditions, it's critical that you manage it carefully to help prevent the onset of heart failure.
Which findings will the nurse likely observe when a patient has right sided heart failure?Shortness of breath (dyspnea), even after only a small amount of exertion. Weakness and lethargy. Fatigue. Swelling (edema), that often involves not only the ankles and lower extremities but also the thighs, abdomen, and chest.
