A nurse is providing care for a client following a cardiac arrest due to pulseless electrical activity (PEA). Which of the following alterations are causes of PEA? (Select All that Apply.)
A. Hypertension
Hypertension: Hypertension, or high blood pressure, is not typically a direct cause of PEA. While uncontrolled hypertension can contribute to cardiovascular disease and increase the risk of cardiac events such as myocardial infarction, it is not a direct cause of PEA.
B. Hypovolemia
Hypovolemia: Hypovolemia, or low blood volume, is a common cause of PEA. Reduced circulating blood volume leads to decreased preload and inadequate filling of the heart chambers, impairing cardiac output. This can result in ineffective cardiac contractions and the development of PEA.
C. Hypoxia
Hypoxia: Hypoxia, or inadequate oxygenation of tissues, is a significant cause of PEA. Insufficient oxygen delivery to the myocardium impairs cardiac function and can lead to ineffective cardiac contractions. Without adequate oxygenation, the heart is unable to generate sufficient mechanical force to maintain circulation, resulting in PEA.
D. Hyperkalemia
Hyperkalemia: Hyperkalemia, or elevated levels of potassium in the blood, can cause PEA by disrupting cardiac electrical activity. Excessive potassium ions in the extracellular fluid alter the normal myocardial action potential, leading to cardiac conduction abnormalities and potential arrhythmias, including PEA.
E. Hypernatremia
Hypernatremia: Hypernatremia, or elevated levels of sodium in the blood, is not typically a direct cause of PEA. While severe hypernatremia can lead to neurological symptoms and dehydration, it does not directly impair cardiac electrical activity or mechanical function to the extent that it causes PEA.
F. Hyperthermia
Hyperthermia: Hyperthermia, or elevated body temperature, is not typically a direct cause of PEA. While extreme hyperthermia can lead to cardiovascular complications such as heat stroke, it is not a common cause of PEA unless it is associated with severe systemic metabolic derangements.

Full Explanation
Pulseless electrical activity (PEA) refers to a situation in which an electrocardiogram (ECG) shows electrical activity in the heart, but there is no effective mechanical activity and no palpable pulse. PEA can result from various underlying conditions that impair cardiac function or compromise circulation.
A. Hypertension: Hypertension, or high blood pressure, is not typically a direct cause of PEA. While uncontrolled hypertension can contribute to cardiovascular disease and increase the risk of cardiac events such as myocardial infarction, it is not a direct cause of PEA.
B. Hypovolemia: Hypovolemia, or low blood volume, is a common cause of PEA. Reduced circulating blood volume leads to decreased preload and inadequate filling of the heart chambers, impairing cardiac output. This can result in ineffective cardiac contractions and the development of PEA.

A nurse is providing discharge education to a client who has valvular heart disease and peripheral vascular disease. Which of the following should the nurse include in the teaching about valvular heart disease?
A. Comply with compression therapy.
Comply with compression therapy: Compression therapy is commonly used in the management of peripheral vascular disease (PVD), not valvular heart disease. It involves applying external pressure to the limbs to improve circulation and reduce edema. While this intervention may be relevant for a client with PVD, it is not specific to valvular heart disease.
B. Monitor wounds on lower extremities.
Monitor wounds on lower extremities: Monitoring wounds on lower extremities is important for clients with peripheral vascular disease (PVD) to assess for signs of poor wound healing, infection, or tissue ischemia. However, it is not directly related to valvular heart disease. Therefore, while wound monitoring may be appropriate for this client, it is not specific to valvular heart disease education.
C. Take antiplatelet medications as ordered.
Take antiplatelet medications as ordered: Antiplatelet medications, such as aspirin or clopidogrel, are commonly prescribed for clients with peripheral vascular disease (PVD) to reduce the risk of thrombotic events and improve blood flow. However, they are not typically indicated as a primary treatment for valvular heart disease. While some clients with valvular heart disease may have comorbidities that warrant antiplatelet therapy, it is not specific to valvular heart disease education.
D. Monitor for gradual onset of symptoms
Valvular heart disease involves dysfunction of one or more heart valves, leading to impaired blood flow within the heart. The nurse should educate the client on monitoring for the gradual onset of symptoms related to valvular heart disease. These symptoms may include dyspnea (shortness of breath), fatigue, palpitations, chest discomfort, and edema. Monitoring for these symptoms allows for early detection of disease progression or exacerbation, prompting timely intervention and management.

A nurse is providing teaching to newly licensed nurses about cardiac tamponade. Which of the following should the nurse include when teaching about Phase Il cardiac tamponade?
A. Comply with compression therapy.
Compression therapy typically refers to the use of compression garments or devices to improve circulation and reduce swelling in the extremities, particularly in conditions such as venous insufficiency or deep vein thrombosis.While compression therapy may be beneficial for certain circulatory disorders, it is not a standard treatment for cardiac tamponade.Cardiac tamponade is a medical emergency characterized by the accumulation of fluid in the pericardial sac, leading to increased pressure on the heart and impaired cardiac function.Treatment for cardiac tamponade involves prompt recognition and intervention to relieve the pressure on the heart, such as pericardiocentesis or surgical drainage of the pericardial effusion.
B. Monitor wounds on lower extremities.
Monitoring wounds on the lower extremities is essential for assessing healing, preventing complications such as infection, and promoting overall wound care.However, monitoring wounds on the lower extremities is not directly related to the management or monitoring of cardiac tamponade.In cardiac tamponade, the focus of monitoring is on assessing signs and symptoms of cardiac compromise, such as hypotension, tachycardia, dyspnea, and pulsus paradoxus, rather than wound care.
C. Take antiplatelet medications as ordered.
Antiplatelet medications, such as aspirin or clopidogrel, are commonly prescribed to prevent platelet aggregation and reduce the risk of thrombotic events, particularly in patients with cardiovascular disease or a history of myocardial infarction or stroke. While antiplatelet medications may be part of the long-term management of certain cardiac conditions, they are not specific to the treatment or monitoring of cardiac tamponade.The primary treatment for cardiac tamponade involves interventions to relieve the pressure on the heart and restore cardiac function, such as pericardiocentesis or surgical drainage of the pericardial effusion.
D. Monitor for gradual onset of symptoms
Phase II of cardiac tamponade is characterized by a gradual onset of symptoms as the pressure within the pericardial sac increases, leading to impaired cardiac filling and decreased cardiac output.Symptoms may include dyspnea, fatigue, orthopnea, tachycardia, and chest discomfort, which may develop gradually over time. Early recognition of symptoms is crucial for prompt diagnosis and intervention to prevent further deterioration and improve outcomes in patients with cardiac tamponade.
