Ch 29: Management of pts w Complications from Heart Disease

A client develops cardiogenic pulmonary edema and is extremely apprehensive. What medication can the nurse administer with physician orders that will relieve anxiety and slow respiratory rate?

Morphine sulfate- Morphine seems to help relieve respiratory symptoms by depressing higher cerebral centers, thus relieving anxiety and slowing respiratory rate. Morphine also promotes muscle relaxation and reduces the work of breathing. Furosemide is a loop diuretic and will decrease fluid accumulation but will not reduce anxiety. Nitroglycerin will promote smooth muscle relaxation in the vessel walls and will relieve pain but not reduce anxiety. Dopamine is an inotrope that will increase the force of ventricular contraction but will not alleviate anxiety.

A patient is admitted to the intensive care unit (ICU) with left-sided heart failure. What clinical manifestations does the nurse anticipate finding when performing an assessment? (Select all that apply.)

Pulmonary crackles,Dyspnea,Cough- The clinical manifestations of pulmonary congestion associated with left-sided heart failure include dyspnea, cough, pulmonary crackles, and low oxygen saturation levels, but not ascites or jugular vein distention.

Which is a manifestation of right-sided heart failure?

Systemic venous congestion- Right-sided heart failure causes systemic venous congestion and a reduction in forward flow. Left-sided heart failure causes an accumulation of blood in the lungs and a reduction in forward flow or cardiac output that results in inadequate arterial blood flow to the tissues. Some clients with left-sided heart failure get episodes of dyspnea at night, known as paroxysmal nocturnal dyspnea.

Assessment of a client on a medical surgical unit finds a regular heart rate of 120 beats per minute, audible third and fourth heart sounds, blood pressure of 84/64 mm Hg, bibasilar crackles on lung auscultation, and a urine output of 5 mL over the past hour. What is the reason the nurse anticipates transferring the client to the intensive care unit?

The client is going into cardiogenic shock.- This client's findings indicate cardiogenic shock, which occurs when the heart fails to pump properly, impeding blood supply and oxygen flow to vital organs. Cardiogenic shock also may cause cold, clammy skin and generalized weakness, fatigue, and muscle pain as poor blood flow causes lactic acid to accumulate and prevents waste removal. Left-sided and right-sided heart failure eventually cause venous congestion with jugular vein distention and edema as the heart fails to pump blood forward. A ruptured aneurysm causes severe hypotension and a quickly deteriorating clinical status from blood loss and circulatory collapse; this client has low but not severely decreased blood pressure. Also, in ruptured aneurysm, deterioration is more rapid and full cardiac arrest is common.

Which is a classic sign of cardiogenic shock?

Tissue hypoperfusion-Tissue hypoperfusion is manifested as cerebral hypoxia (restlessness, confusion, agitation). Low blood pressure is a classic sign of cardiogenic shock. Hypoactive bowel sounds are classic signs of cardiogenic shock. Decreased urinary output is a classic sign of cardiogenic shock.

A nurse caring for a client recently admitted to the ICU observes the client coughing up large amounts of pink, frothy sputum. Lung auscultation reveals course crackles to lower lobes bilaterally. Based on this assessment, the nurse recognizes this client is developing

decompensated heart failure with pulmonary edema.-Large quantities of frothy sputum, which is sometimes pink or tan (blood tinged), may be produced, indicating acute decompensated heart failure with pulmonary edema. These signs can be confused with pneumonia and tuberculosis, however the patient reveals course crackles upon auscultation which is indicative of pulmonary edema. A patient with acute COPD would have diminished lung sounds bilaterally.

A client who has developed congestive heart failure must learn to make dietary adaptations. The client should avoid:

canned peas.-There is a wide variety of foods that the client can still eat; the key is to have low-salt content. Canned vegetables are usually very high in salt or sodium, unless they have labels such as low-salt or sodium free or salt free. It is important to read food labels and look for foods that contain less than 300 mg sodium/serving.

A client has had an echocardiogram to measure ejection fraction. The nurse explains that ejection fraction is the percentage of blood the left ventricle ejects upon contraction. What is the typical percentage of blood a healthy heart ejects?

55%- Normally, a healthy heart ejects 55% or more of the blood that fills the left ventricle during diastole.

Before discharge, which instruction should a nurse give to a client receiving digoxin?

"Call the physician if your heart rate is above 90 beats/minute."-The nurse should instruct the client to notify the physician if his heart rate is greater than 90 beats/minute because cardiac arrhythmias may occur with digoxin toxicity. To prevent toxicity, the nurse should instruct the client never to take an extra dose of digoxin if he misses a dose. The nurse should show the client how to take his pulse and tell him to call the physician if his pulse rate drops below 60 beats/minute — not 80 beats/minute, which is a normal pulse rate and doesn't warrant action. The client shouldn't take digoxin with meals; doing so slows the absorption rate.

A nurse is caring for a client with heart failure. The nurse knows that the client has left-sided heart failure when the client makes which statement?

"I sleep on three pillows each night."- Orthopnea is a classic sign of left-sided heart failure. The client commonly sleeps on several pillows at night to help facilitate breathing. Swollen feet, ascites, and anorexia are signs of right-sided heart failure.

The nurse is teaching a client with heart failure about digoxin. What statements by the client indicate the teaching is effective? Select all that apply.

"I will watch my urine output to be sure that the medication is not affecting my kidneys." "If I take my digoxin I should have limited episodes of shortness of breath."-Digoxin is excreted by the kidneys and causes renal failure, so the client should monitor urine output. Digoxin therapy will increase ventricular output, so it can be effective in decreasing heart failure symptoms like shortness of breath. Digoxin toxicity may can anorexia, not increased appetite. Digoxin therapy will slow AV conduction, not increase heart rate or blood pressure. A client taking digoxin therapy will have levels drawn if symptoms of toxicity or renal function changes are present.

A client in the emergency room is in cardiac arrest and exhibiting pulseless electrical activity (PEA) on the cardiac monitor. What will be the nurse's next action?

Administer epinephrine.- PEA can be caused by hypovolemia, hypoxia, hypothermia, hyperkalemia, massive pulmonary embolism, myocardial infarction, and medication overdose (beta blockers, calcium channel blockers). PEA is treated with epinephrine according to advanced life support protocol. Applying oxygen or analyzing an arterial blood gas will not change the client's heart rhythm. PEA is treated until there is no change in the client's rhythm after treatments.

A total artificial heart (TAH) is an electrically powered pump that circulates blood into the pulmonary artery and the aorta, thus replacing the functions of both the right and left ventricles. What makes it different from an LVAD?

An LVAD only supports a failing left ventricle.- A TAH is considered an extension of LVADs, which only support a failing left ventricle. TAHs are targeted for clients who are unlikely to live more than a month without further interventions.

Which measurement should a nurse use to monitor the respiratory status of a client with pulmonary edema?

Arterial blood gas (ABG) analysis- ABG analysis is the best measure for determining the extent of hypoxia caused by pulmonary edema and for monitoring the effects of therapy. Although a nurse can use any of the options to detect pulmonary changes, assessment of skin color and assessment of lung fields commonly are subject to interpretation by practitioners. The use of pulse oximetry is unreliable, especially in the case of severe vasoconstriction as is present in pulmonary edema.

A client arrives at the ED with an exacerbation of left-sided heart failure and reports shortness of breath. Which is the priority nursing intervention?

Assess oxygen saturation- Assessment is priority to determine the severity of the exacerbation. It is important to assess the oxygen saturation in a client with heart failure because below-normal oxygen saturation can be life-threatening. Treatment options vary according to the severity of the client's condition and may include supplemental oxygen, oral and IV medications, major lifestyle changes, implantation of cardiac devices, and surgical approaches. The overall goal of treatment of heart failure is to relieve symptoms and reduce the workload on the heart by reducing afterload and preload.

The nurse is teaching a group of clients with heart failure about how to decrease leg edema. What dietary advice will the nurse give to clients with severe heart failure?

Avoid the intake of processed and commercially prepared foods.- Until edema resolves, a client with severe heart failure requires restriction of sodium to 500 to 1,000 mg/day. Therefore, processed and commercially prepared foods are eliminated. Vegetables with natural sodium, for example, beets, carrots, and "greens," should be avoided. Fresh, frozen, and canned fruit and fruit juices are not restricted. Increased intake of red meat should not be encouraged; it should be restricted to 6 oz per day.

A client with pulmonary edema has been admitted to the ICU. What would be the standard care for this client?

BP and pulse measurements every 15 to 30 minutes- Bedside ECG monitoring is standard, as are continuous pulse oximetry, automatic BP, and pulse measurements approximately every 15 to 30 minutes.

A patient is undergoing a pericardiocentesis. Following withdrawal of pericardial fluid, which assessment by the nurse indicates that cardiac tamponade has been relieved?

Decrease in central venous pressure (CVP)-A resulting decrease in CVP and an associated increase in blood pressure after withdrawal of pericardial fluid indicate that the cardiac tamponade has been relieved. An absence of cough would not indicate the absence of cardiac tamponade.

A client has been prescribed furosemide 80 mg twice daily. The asymptomatic client begins to have rare premature ventricular contractions followed by runs of bigeminy with stable signs. What action will the nurse perform next?

Check the client's potassium level.- The client is asymptomatic but has had a change in heart rhythm. More information is needed before calling the health care provider. Because the client is taking furosemide, a potassium-wasting diuretic, the next action would be to check the client's potassium level. The nurse would then call the health care provider with a more complete database. The health care provider will need to be notified after the nurse checks the latest potassium level. The intake and output will not change the heart rhythm. Administering potassium requires a health care provider's order.

A client with chronic heart failure is able to continue with his regular physical activity and does not have any limitations as to what he can do. According to the New York Heart Association (NYHA), what classification of chronic heart failure does this client have?

Class I (Mild)- Class I is when ordinary physical activity does not cause undue fatigue, palpitations, or dyspnea. The client does not experience any limitation of activity. Class II (Mild) is when the client is comfortable at rest, but ordinary physical activity results in fatigue, heart palpitations, or dyspnea. Class III (Moderate) is when there is marked limitation of physical activity. The client is comfortable at rest, but less than ordinary activity causes fatigue, heart palpitations, or dyspnea. Class IV (Severe), the client is unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency occur at rest. Discomfort is increased if any physical activity is undertaken.

A client is exhibiting digitalis toxicity. Which of the following medications would the nurse expect to be ordered for this client?

Digoxin immune FAB- Digibind binds with digoxin and makes it unavailable for use. The digibind dosage is based on the digoxin level and the patient's weight. Ibuprofen, warfarin, and amlodipine are not used to reverse the effects of digoxin.

Which medication reverses digitalis toxicity?

Digoxin immune FAB-Digoxin immune FAB binds with digoxin and makes it unavailable for use. The dosage is based on the digoxin concentration and the client's weight. Ibuprofen, warfarin, and amlodipine are not used to reverse the effects of digoxin.

Which assessment parameter is important for the client diagnosed with congestive heart failure?

Distended veins- During a head-to-toe assessment of a client with congestive heart failure, the nurse checks for dyspnea, auscultates apical heart rate, counts radial heart rate, measures BP, checks for distended neck veins, and documents any signs of peripheral edema, lethargy, or confusion. The nurse need not examine joints for crepitus, eyes for excess tearing, or signs of photosensitivity because these are not symptoms of congestive heart failure.

Which is a cerebrovascular manifestation of heart failure?

Dizziness- Cerebrovascular manifestations of heart failure include dizziness, lightheadedness, confusion, restlessness, and anxiety. Tachycardia is a cardiovascular manifestation. Ascites is a gastrointestinal manifestation. Nocturia is a renal manifestation.

The nurse is obtaining data on an older adult client. What finding may indicate to the nurse the early symptom of heart failure?

Dyspnea on exertion- Left-sided heart failure produces hypoxemia as a result of reduced cardiac output of arterial blood and respiratory symptoms. Many clients notice unusual fatigue with activity. Some find exertional dyspnea to be the first symptom. An increase in urinary output may be seen later as fluid accumulates. Hypotension would be a later sign of decompensating heart failure as well as tachycardia.

Which diagnostic study is usually performed to confirm the diagnosis of heart failure?

Echocardiogram- An echocardiogram is usually performed to confirm the diagnosis of heart failure. ECG, serum electrolytes, and a BUN are usually completed during the initial workup.

The nurse is caring for a client with heart failure. What procedure should the nurse prepare the client for in order to determine the ejection fraction to measure the efficiency of the heart as a pump?

Echocardiogram-The heart's ejection fraction is measured using an echocardiogram or multiple gated acquisition scan. A pulmonary arteriography is used to confirm cor pulmonale. A chest radiograph can reveal the enlargement of the heart. An electrocardiogram is used to determine the activity of the heart's conduction system.

Which is a characteristic of right-sided heart failure?

Jugular vein distention- Jugular vein distention is a characteristic of right-sided heart failure. Dyspnea, pulmonary crackles, and cough are manifestations of left-sided heart failure.

The nurse is teaching a client about lifestyle modifications after a heart failure diagnosis. What will be included in the teaching?

Engage in exercise daily.- Lifestyle recommendations after heart failure include restriction of dietary sodium; avoidance of excessive fluid intake, excessive alcohol intake, and smoking; weight reduction when indicated; and regular exercise. The restriction of potassium is not required. Drinking 3 liters of fluid per day would be excessive for a client with heart failure.

A client has a significant history of congestive heart failure. What should the nurse specifically assess during the client's semiannual cardiology examination? Select all that apply.

Examine the client's neck for distended veins.&Monitor the client for signs of lethargy or confusion.- During a head-to-toe assessment of a client with congestive heart failure, the nurse checks for dyspnea, auscultates apical heart rate and counts radial heart rate, measures BP, and documents any signs of peripheral edema, lethargy, or confusion. Excess tears are not part of the checklist.

A client with acute pericarditis is exhibiting distended jugular veins, tachycardia, tachypnea, and muffled heart sounds. The nurse recognizes these as symptoms of what occurrence?

Excess pericardial fluid compresses the heart and prevents adequate diastolic filling.- The cardinal signs of cardiac tamponade are falling systolic blood pressure, narrowing pulse pressure, rising venous pressure (increased JVD), and distant (muffled) heart sounds. Increased pericardial pressure, reduced venous return to the heart, and decreased carbon dioxide result in cardiac tamponade (e.g., compression of the heart).

Which medication is categorized as a loop diuretic?

Furosemide- Furosemide is commonly used to treat cardiac failure. Loop diuretics inhibit sodium and chloride reabsorption mainly in the ascending loop of Henle. Chlorothiazide and chlorthalidone are categorized as thiazide diuretics. Spironolactone is categorized as a potassium-sparing diuretic.

The nurse is caring for a client with suspected right-sided heart failure. What would the nurse know that clients with suspected right-sided heart failure may experience?

Gradual unexplained weight gain- Clients with right-sided heart failure may have a history of gradual, unexplained weight gain from fluid retention. Left-sided heart failure produces paroxysmal nocturnal dyspnea, which may prompt the client to use several pillows in bed or to sleep in a chair or recliner. Right-sided heart failure does not cause increased perspiration or increased urine output.

A new client has been admitted with right-sided heart failure. When assessing this client, the nurse knows to look for which finding?

Jugular venous distention- When the right ventricle cannot effectively pump blood from the ventricle into the pulmonary artery, the blood backs up into the venous system and causes jugular venous distention and congestion in the peripheral tissues and viscera. All the other choices are symptoms of left-sided heart failure.

A nurse is caring for a client experiencing dyspnea, dependent edema, hepatomegaly, crackles, and jugular vein distention. What condition should the nurse suspect?

Heart failure- A client with heart failure has decreased cardiac output caused by the heart's decreased pumping ability. A buildup of fluid occurs, causing dyspnea, dependent edema, hepatomegaly, crackles, and jugular vein distention. A client with pulmonary embolism experiences acute shortness of breath, pleuritic chest pain, hemoptysis, and fever. A client with cardiac tamponade experiences muffled heart sounds, hypotension, and elevated central venous pressure. A client with tension pneumothorax has a deviated trachea and absent breath sounds on the affected side as well as dyspnea and jugular vein distention.

A client is already being treated for hypertension. The doctor is concerned about the potential for heart failure, and has the client return for regular check-ups. What does hypertension have to do with heart failure?

Hypertension causes the heart's chambers to enlarge and weaken.- Hypertension causes the heart's chambers to enlarge and weaken, making it impossible for the ventricles to eject all the blood they receive.

The pathophysiology of pericardial effusion is associated with all of the following except:

Increased venous return.-Venous return is increased because there is an increase in the pericardial fluid, which raises the pressure within the pericardial sac and compresses the heart.

A nurse is assessing a client with congestive heart failure for jugular vein distension (JVD). Which observation is important to report to the physician?

JVD is noted 4 cm above the sternal angle- JVD is assessed with the client sitting at a 45° angle. Jugular vein distention greater than 4 cm above the sternal angle is considered abnormal and is indicative of right ventricular failure. .

The clinical manifestations of cardiogenic shock reflect the pathophysiology of heart failure (HF). By applying this correlation, the nurse notes that the degree of shock is proportional to which of the following?

Left ventricular function- The signs and symptoms of cardiogenic shock reflect the circular nature of the pathophysiology of HF. The degree of shock is proportional to the extent of left ventricular dysfunction.

Which feature is the hallmark of systolic heart failure?

Low ejection fraction (EF)- A low EF is a hallmark of systolic heart failure (HF); the severity of HF is frequently classified according to the client's symptoms.

The nurse is providing discharge instructions to a client with heart failure preparing to leave the following day. What type of diet should the nurse request the dietitian to discuss with the client?

Low-sodium diet-Medical management of both left-sided and right-sided heart failure is directed at reducing the heart's workload and improving cardiac output primarily through dietary modifications, drug therapy, and lifestyle changes. A low-sodium diet is prescribed, and fluids may be restricted. Because the client will be on a diuretic such as Lasix, he may become potassium depleted and would need potassium in the diet. A low-cholesterol and low-fat diet may be ordered but are not specific to the heart failure.

Which action will the nurse include in the plan of care for a client admitted with acute decompensated heart failure (ADHF) who is receiving milrinone?

Monitor blood pressure frequently- Milrinone is a phosphodiesterase inhibitor that delays the release of calcium from intracellular reservoirs and prevents the uptake of extracellular calcium by the cells. This promotes vasodilation, resulting in decreased preload and afterload and reduced cardiac workload. Milrinone is administered intravenously to clients with severe HF, including those who are waiting for a heart transplant. Because the drug causes vasodilation, the client's blood pressure is monitored before administration because if the client is hypovolemic the blood pressure could drop quickly. The major side effects are hypotension and increased ventricular dysrhythmias. Blood pressure and the electrocardiogram (ECG) are monitored closely during and after infusions of milrinone.

A client is admitted to the ICU with a diagnosis of heart failure. The client is exhibiting symptoms of weakness, ascites, weight gain, and jugular vein distention. The nurse would know that the client is exhibiting signs of what kind of heart failure?

Right-sided heart failure- Signs and symptoms of Right Ventricular Failure include: Weakness; Ascites; Weight gain; Nausea, vomiting; Dysrhythmias; Elevated central venous pressure; Jugular vein distention. The scenario does not indicate whether the heart failure is chronic or acute. Therefore, options A, B, and C are incorrect.

The client with cardiac failure is taught to report which symptom to the physician or clinic immediately?

Persistent cough- Persistent cough may indicate an onset of left-sided heart failure. Loss of appetite, weight gain, interrupted sleep, unusual shortness of breath, and increased swelling should also be reported immediately.

The nurse is preparing to administer furosemide to a client with severe heart failure. What lab study should be of most concern for this client while taking furosemide?

Potassium level of 3.1- Severe heart failure usually requires a loop diuretic such as furosemide (Lasix). These drugs increase sodium and therefore water excretion, but they also increase potassium excretion. If a client becomes hypokalemic, digitalis toxicity is more likely. The BNP does not demonstrate a severe heart failure. Sodium level of 135 is within normal range, as is the hemoglobin level.

Which term describes the degree of stretch of the ventricular cardiac muscle fibers at the end of diastole?

Preload-Preload is the degree of stretch of the ventricular cardiac muscle fibers at the end of diastole. Afterload is the amount of resistance to ejection of blood from a ventricle. The ejection fraction is the percentage of blood volume in the ventricles at the end of diastole that is ejected during systole. Stroke volume is the amount of blood pumped out of the ventricle with each contraction.

A hospitalized client with heart failure puts on the call light and states, "I've become very short of breath, and I've been coughing up this pink frothy sputum." The nurse immediately suspects which of the following complications?

Pulmonary edema- When the left ventricle fails, blood backs up into the pulmonary system. Large quantities of frothy sputum, which is sometimes blood-tinged, may be produced, indicating severe pulmonary congestion or pulmonary edema.

A client has a myocardial infarction in the left ventricle and develops crackles bilaterally; 3-pillow orthopnea; an S3 heart sound; and a cough with pink, frothy sputum. The nurse obtains a pulse oximetry reading of 88%. What do these signs and symptoms indicate for this client?

The development of left-sided heart failure-When the left ventricle fails, the heart muscle cannot contract forcefully enough to expel blood into the systemic circulation. Blood subsequently becomes congested in the left ventricle, left atrium, and finally the pulmonary vasculature. Symptoms of left-sided failure include fatigue; paroxysmal nocturnal dyspnea; orthopnea; hypoxia; crackles; cyanosis; S3 heart sound; cough with pink, frothy sputum; and elevated pulmonary capillary wedge pressure. COPD develops over many years and does not develop after a myocardial infarction. The development of right-sided heart failure would generally occur after a right ventricle myocardial infarction or after the development of left-sided heart failure. Cor pulmonale is a condition in which the heart is affected secondarily by lung damage.

A client is awaiting the availability of a heart for transplant. What option may be available to the client as a bridge to transplant?

Ventricular assist device (VAD)- VADs may be used for one of three purposes:(1) a bridge to recovery, (2) a bridge to transport, or (2) destination therapy (mechanical circulatory support when there is no option for a heart transplant). An implanted cardioverter-defibrillator or pacemaker is not a bridge to transplant and will only correct the conduction disturbance and not the pumping efficiency. An IABP is a temporary, secondary mechanical circulatory pump to supplement the ineffectual contraction of the left ventricle. The IABP is intended for only a few days

A client is at risk for excess fluid volume. Which nursing intervention ensures the most accurate monitoring of the client's fluid status?

Weighing the client daily at the same time each day- Increased fluid volume leads to rapid weight gain — 2.2 lb (1 kg) for each liter of fluid retained. Weighing the client daily at the same time and in similar clothing provides more objective data than measuring fluid intake and output, which may be inaccurate because of omitted measurements such as insensible losses. Changes in vital signs are less reliable than daily weight because these changes usually are subtle during early stages of fluid retention. Weight gain is an earlier sign of excess fluid volume than crackles, which represent pulmonary edema. The nurse should plan to detect fluid accumulation before pulmonary edema occurs.

A client with left-sided heart failure reports increasing shortness of breath and is agitated and coughing up pink-tinged, foamy sputum. The nurse should recognize these findings as signs and symptoms of what condition?

acute pulmonary edema.- Shortness of breath, agitation, and pink-tinged, foamy sputum signal acute pulmonary edema. This condition results when decreased contractility and increased fluid volume and pressure in clients with heart failure drive fluid from the pulmonary capillary beds into the alveoli. In right-sided heart failure, the client would exhibit hepatomegaly, jugular vein distention, and peripheral edema. In pneumonia, the client would have a temperature spike and sputum that varies in color. Cardiogenic shock is indicated by signs of hypotension and tachycardia.

A client asks the nurse if systolic heart failure will affect any other body function. What body system response correlates with systolic heart failure (HF)?

decrease in renal perfusion- A decrease in renal perfusion due to low cardiac output (CO) and vasoconstriction causes the release of renin by the kidney. Systolic HF results in decreased blood volume being ejected from the ventricle. Sympathetic stimulation causes vasoconstriction of the skin, gastrointestinal tract, and kidneys. Dehydration does not correlate with systolic heart failure.

The nurse is admitting a client with frothy pink sputum. What does the nurse suspect is the primary underlying disorder of pulmonary edema?

decreased left ventricular pumping- Pulmonary edema is an acute event that results from heart failure. Myocardial scarring, resulting from ischemia, limits the distensibility of the ventricle, making it vulnerable to demands for increased workload. When the demand on the heart increases, there is resistance to left ventricular filling and blood backs up into the pulmonary circulation. Pulmonary edema quickly develops.

The nurse is providing care to a client with cardiogenic shock requiring a intra-aortic balloon pump (IABP). What is the therapeutic effect of the IABP therapy?

decreased left ventricular workload-The signs and symptoms of cardiogenic shock reflect the circular nature of the pathophysiology of HF. The therapeutic effect is decreased left ventricular workload. The IABP does not change right ventricular workload. The IABP increases perfusion to the coronary and peripheral arteries. The renal perfusion is not affected by IABP.

Frequently, what is the earliest symptom of left-sided heart failure?

dyspnea on exertion- Dyspnea on exertion is often the earliest symptom of left-sided heart failure.

A client has been having cardiac symptoms for several months and is seeing a cardiologist for diagnostics to determine the cause. How will the client's ejection fraction be measured?

echocardiogram- The heart's ejection fraction is measured using an echocardiogram or multiple gated acquisition scan, not an electrocardiogram or cardiac ultrasound. Cardiac catheterization is not the diagnostic tool for this measurement.

The nurse is assessing a newly admitted client with chest pain. What medical disorder is most likely causing the client to have jugular vein distention?

heart failure- Elevated venous pressure, exhibited as jugular vein distention, indicates the heart's failure to pump. Jugular vein distention isn't a symptom of abdominal aortic aneurysm or pneumothorax. If severe enough, an MI can progress to heart failure, but an MI alone doesn't cause jugular vein distention.

A nurse is administering digoxin. What client parameter would cause the nurse to hold the digoxin and notify the health care prescriber?

heart rate of 55 beats per minute- Digoxin therapy slows conduction through the AV node. A heart rate of 55 is slow and the digoxin therapy may slow the heart rate further. Blood pressure of 125/80 is normal. Urine output of 300 mL is adequate, so the kidneys are functioning. Atrial fibrillation is not a parameter to hold medication.

The nurse is caring for a client with advanced heart failure. What treatment will be considered after all other therapies have failed?

heart transplant- Heart transplantation involves replacing a person's diseased heart with a donor heart. This is an option for advanced HF patients when all other therapies have failed. A ventricular access device, ICD, and cardiac resynchronization therapy would be tried prior to a heart transplant.

A client has been admitted to the cardiac step-down unit with acute pulmonary edema. Which symptoms would the nurse expect to find during assessment?

moist, gurgling respirations- Clients with acute pulmonary edema experience sudden dyspnea, wheezing, orthopnea, cough, cyanosis, and tachycardia. Respirations sound moist or gurgling. Drowsiness and numbness are not considered issues. Increased cardiac output is not part of this checklist. Hypertension is not an immediate symptom.

A client is prescribed digitalis medication. Which condition should the nurse closely monitor when caring for the client?

nausea and vomiting- Digitalis medications are potent and may cause various toxic effects. The nurse should monitor the client for signs of digitalis toxicity, not just during the initial period of therapy, but throughout care management. The most common signs and symptoms include nausea and vomiting which can lead to dehydration and electrolyte imbalance. Symptoms of toxicity do not include vasculitis, flexion contractures, or enlargement of joints.

The nurse is administering digoxin to a client with heart failure. What laboratory value may predispose the client to digoxin toxicity?

potassium level of 2.8 mEq/L

A client with a history of an anterior wall myocardial infarction is being transferred from the coronary care unit (CCU) to the cardiac step-down unit (CSU). While giving a report to the CSU nurse, the CCU nurse says, "His pulmonary artery wedge pressures have been in the high normal range." What additional assessment information would be important for the CSU nurse to obtain?

pulmonary crackles- High pulmonary artery wedge pressures are diagnostic for left-sided heart failure. With left-sided heart failure, pulmonary edema can develop causing pulmonary crackles. In left-sided heart failure, hypotension may result and urine output will decline. Dry mucous membranes aren't directly associated with elevated pulmonary artery wedge pressures.

A client who was admitted to the hospital with a diagnosis of thrombophlebitis 1 day ago suddenly reports chest pain and shortness of breath and is visibly anxious. The nurse immediately assesses the client for other signs and symptoms of

pulmonary embolism.- Pulmonary embolism is a potentially life-threatening disorder typically caused by blood clots in the lungs. This disorder poses a particular threat to people with cardiovascular disease. Blood clots that form in the deep veins of the legs and embolize to the lungs can cause a pulmonary infarction, whereby emboli mechanically obstruct the pulmonary vessels, cutting off the blood supply to sections of the lung. Clinical indicators of pulmonary embolism can vary but typically include dyspnea, pleuritic chest pain, and tachypnea.

A nurse suspects that a client has digoxin toxicity. The nurse should assess for:

vision changes.- Vision changes, such as halos around objects, are signs of digoxin toxicity. Hearing loss can be detected through hearing assessment; however, it isn't a common sign of digoxin toxicity. Intake and output aren't affected unless there is nephrotoxicity, which is uncommon. Gait changes are also uncommon.
