The nurse notes that the patient was taking clopidogrel (Plavix) at home. The nurse knows that this medication belongs to which drug class?

Antiplatelet

An elderly client is being monitored for evidence of congestive heart failure. To detect early signs of heart failure, the nurse would instruct the certified nursing attendant (CNA) to do which of the following during care of the patient?

Accurately weigh the patient, and report and record the readings. Due to fluid accumulation, an expanded blood volume can result when the heart fails. Body weight is a sensitive indicator of water and sodium retention, which will manifest itself with edema, dyspnea - especially nocturnal - and pedal edema. Patients also should be instructed about the need to perform daily weights upon discharge to monitor body water

A 54-year-old male patient who had bladder surgery 2 days ago develops acute decompensated heart failure (ADHF) with severe dyspnea. Which action by the nurse would be indicated first?

Assist the patient to a sitting position with arms on the overbed table. The nurse should place the patient with ADHF in a high Fowler's position with the feet horizontal in the bed or dangling at the bedside. This position helps decrease venous return because of the pooling of blood in the extremities. This position also increases the thoracic capacity, allowing for improved ventilation.

Which condition most commonly results in CAD?

Atherosclerosis

Postoperative care of a patient undergoing coronary artery bypass graft (CABG) surgery includes monitoring for what common complication?

Atrial dysrhythmias STUDY TIP: The old standbys of enough sleep and adequate nutritional intake also help keep excessive stress at bay. Although nursing students learn about the body's energy needs in anatomy and physiology classes, somehow they tend to forget that glucose is necessary for brain cells to work. Skipping breakfast or lunch or surviving on junk food puts the brain at a disadvantage

The nurse is caring for a patient with manifestations of left-sided heart failure. What is the priority nursing intervention?

Auscultate lung sounds explanation: excess fluid leads to pulmonary congestion

A patient with chronic stable angina has received a prescription for nitroglycerin (Nitrolingual). The nurse tells the patient that orthostatic hypotension is an important side effect of this drug. To prevent complications associated with the side effect, what should the nurse include in the patient's teaching?

Avoid sudden changes in position after taking nitroglycerin to prevent falls Explanation: Nitrates cause vasodilatation, which in turn causes peripheral pooling of blood. On changing position suddenly (from recumbent to erect posture), there is a sudden drop of blood pressure, which is known as orthostatic hypotension. This decreases the blood supply to the brain, which may lead to dizziness and falling. Headaches and flushing are not associated with orthostatic hypotension. If there is no tingling sensation on administering the drug, then the medication may be expired or ineffective.

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?

Awakening from sleep with feelings of suffocation

A client with myocardial infarction has been transferred from a coronary care unit to a general medical unit with cardiac monitoring via telemetry. A nurse plans to allow for which of the following client activities?

Blood Pressue - hypotension = adverse effect

A stable patient with acute decompensated heart failure (ADHF) suddenly becomes dyspneic. Before positioning the patient on the bedside, what should the nurse assess first?

Blood Pressure

Beyond the first year after a heart transplant, the nurse knows that what is a major cause of death?

Cardiac vasculopathy Beyond the first year after a heart transplant, malignancy (especially lymphoma) and cardiac vasculopathy (accelerated CAD) are the major causes of death. During the first year after transplant, infection and acute rejection are the major causes of death. Immunosuppressive therapy will be used for posttransplant management to prevent rejection and increases the patient's risk of an infection.

A client is wearing a continuous cardiac monitor, which begins to sound its alarm. A nurse sees no electrocardiogram complexes on the screen. The first action of the nurse is to:

Check the client status and lead placement Sudden loss of electrocardiogram complexes indicates ventricular asystole or possible electrode displacement.

A male patient with a long-standing history of heart failure has recently qualified for hospice care. What measure should the nurse now prioritize when providing care for this patient?

Choose interventions to promote comfort and prevent suffering.

A nurse is assessing a 15-year-old patient who has a BMI over 30. What is the first change in the coronary artery that could make the patient susceptible to coronary artery disease?

A 67-year-old patient has coronary artery disease (CAD). Which question should the nurse ask to assess a need for additional teaching?

Did you have any recent weight gain?

The patient's laboratory results reveal a potassium level of 2.6 mEq/L. The nurse should notify the health care provider and withhold which scheduled medication?

Digoxin (Lanoxin) Explanation: Hypokalemia is the most significant risk factor for digoxin toxicity. The dose should be held and the health care provider should be notified with a plan to provide additional potassium supplementation. Potassium should be administered, not held, in the patient with hypokalemia.

When administered a thrombolytic drug to the client experiencing an MI, the nurse explains to him that the purpose of this drug is to:

Dissolve any potential clots

To evaluate a client's condition following cardiac catheterization, the nurse will palpate the pulse:

Distal to the catheter insertion Palpating pulses distal to the insertion site is important to evaluate for thrombophlebitis and vessel occlusion. They should be bilateral and strong.

A client with no history of cardiovascular disease comes into the ambulatory clinic with flulike symptoms. The client suddenly complains of chest pain. Which of the following questions would best help a nurse to discriminate pain caused by a non-cardiac problem?

Does the pain get worse when you breath in? Chest pain is assessed by using the standard pain assessment parameters.

Which of the following diagnostic tools is most commonly used to determine the location of myocardial damage?

ECG The ECG is the quickest, most accurate, and most widely used tool to determine the location of myocardial infarction.

A patient is suspected of having heart failure. The nurse recognizes that which diagnostic tests are commonly used to make this diagnosis? Select all that apply.

ECG echocardiogram Chest xray

Which of the following diagnostic tests is preferred for evaluating heart valve function?

Echocardiogram b/c it allows the visualization of the valves as they open and close

An echocardiogram for a patient indicates enlarged ventricles of the heart. The nurse caring for the patient understands that this condition has occurred as a result of a chronic condition. What could be the cause of the cardiac dilation?

Elevated pressure in the ventricles

A 60-year-old male client comes into the emergency department with complaints of crushing chest pain that radiates to his shoulder and left arm. The admitting diagnosis is acute myocardial infarction. Immediate admission orders include oxygen by NC at 4L/minute, blood work, chest x-ray, an ECG, and 2mg of morphine given intravenously.

The patient with chronic heart failure is being discharged from the hospital. What information should the nurse emphasize in the patient's discharge teaching to prevent progression of the disease to acute decompensated heart failure (ADHF)?

Take meds as prescribed Explanation: The goal for the patient with chronic heart failure is to avoid exacerbations and hospitalization. Taking the medications as prescribed along with nondrug therapies, such as alternating activity with rest, will help the patient meet this goal

A70-year-old woman with chronic heart failure and atrial fibrillation asks the nurse why warfarin (Coumadin) has been prescribed for her to continue at home. Which response by the nurse is accurate?

The medication prevents blood clots from forming in your heart."

A patient with heart failure and atrial fibrillation asks why an anticoagulant (heparin) has been prescribed. What explanation should the nurse provide?

To dissolve the atrial thrombus that may lead to stroke Explanation: In atrial fibrillation, the formation of thrombus is common in the atria, which may further form emboli and lead to a stroke. Therefore, anticoagulants are administered.

A nurse is caring for a patient with chest pain that began 10 days ago. Which serum cardiac marker should the nurse review to determine if a myocardial infarction occurred 10 days ago?

Troponin Explanation: Troponin is a serum cardiac marker that is detectable in the blood up to 2 weeks after myocardial injury and is used to diagnose a MI. Troponin has two subtypes: cardiac-specific troponin T (cTnT) and cardiac-specific troponin I (cTnI). Serum levels of cTnT and cTnI begin to increase 4 to 6 hours after the onset of myocardial injury, peak at 10 to 24 hours, and return to normal over 10 to 14 days.

Which of the following blood tests is most indicative of cardiac damage?

Troponin 1 Levels Troponin I levels rise rapidly and are detectable within 1 hour of myocardial injury. Troponin levels aren't detectable in people without cardiac injury.

Which of the following diagnostic studies most likely would confirm a myocardial infarction?

Troponin T levels

Auscultation of a patient's heart reveals the presence of a murmur. What is this assessment finding a result of?

Turbulent blood flow across a heart valve

A patient is scheduled to receive a dose of digoxin (Lanoxin). The morning laboratory results are as follows: sodium 145 mEq/L, potassium 3.2 mEq/L, chloride 98 mEq/L, and glucose 78 mg/dL. What is the priority nursing action?

Withhold the dose and report the potassium level

The nurse is preparing to administer digoxin to a patient with heart failure. In preparation, laboratory results are reviewed with the following findings: sodium 139 mEq/L, potassium 5.6 mEq/L, chloride 103 mEq/L, and glucose 106 mg/dL. What should the nurse do next?

Withhold the dose and report the potassium level Explanation: The normal potassium level is 3.5 to 5.0 mEq/L. The patient is hyperkalemic, which makes them more prone to digoxin toxicity. For this reason, the nurse should withhold the dose and report the K+ level. The health care provider may prescribe the digoxin to be given once the potassium level has been treated and decreases to within normal range

If a patient has decreased cardiac output caused by fluid volume deficit and marked vasodilation, the regulatory mechanism that will increase the blood pressure by improving both of these is

activation of the renin-angiotensin-aldosterone system

The nurse recognizes the need for more frequent monitoring of electrolytes when a patient prescribed digitalis (Lanoxin) receives

any form of diuretic

Thrombolytic drugs

are administered within the first 6 hours after onset of a MI to lyse clots and reduce the extent of myocardial damage.

When a person's blood pressure rises, the homeostatic mechanism to compensate for an elevation involves stimulation of

baroreceptors that inhibit the sympathetic nervous system, causing a decreased heart rate.

An important nursing responsibility for a patient having an invasive cardiovascular diagnostic study is

checking the peripheral pulses and percutaneous site.

Chest X-ray

determines size of the heart

A nurse has identified a group of people who are at risk for developing coronary artery disease. To prevent atherosclerosis, the nurse advises a reduction in salt consumption. How does salt consumption increase the risk of developing atherosclerosis?
