Mi final

) are a first-line therapy for this type of angina. Lipid-lowering drugs help reduce atherosclerosis (i.e., plaque formation), and β-adrenergic blockers decrease sympathetic stimulation of the heart (i.e., palpitations). Medications or activities that increase myocardial contractility will increase the incidence of angina by increasing oxygen demand.

29. When caring for a patient who has just arrived on the medical-surgical unit after having cardiac catheterization, which nursing intervention should the nurse delegate to a licensed practical/vocational nurse (LPN/LVN)? a. Give the scheduled aspirin and lipid-lowering medication. b. Perform the initial assessment of the catheter insertion site. c. Teach the patient about the usual postprocedure plan of care. d. Titrate the heparin infusion according to the agency protocol.

ANS: A Administration of oral medications is within the scope of practice for LPNs/LVNs. The initial assessment of the patient, patient teaching, and titration of IV anticoagulant medications should be done by the registered nurse (RN).

A nurse is giving aspirin to a patient during acute management of STEMI. The patient asks why a chewable tablet is given. Which response by the nurse is correct? a. "Aspirin is absorbed more quickly when it is chewed." b. "Chewing aspirin prevents it from being metabolized by the liver." c. "Chewing aspirin prevents stomach irritation." d. "More of the drug is absorbed when aspirin is chewed."

ANS: A Aspirin should be chewed to allow rapid absorption across the buccal mucosa. Chewing aspirin does not affect hepatic metabolism, stomach irritation, or the amount absorbed.

34. Which information about a patient who has been receiving thrombolytic therapy for an acute myocardial infarction (AMI) is most important for the nurse to communicate to the health care provider? a. No change in the patient's chest pain b. An increase in troponin levels from baseline c. A large bruise at the patient's IV insertion site d. A decrease in ST-segment elevation on the electrocardiogram

ANS: A Continued chest pain suggests that the thrombolytic therapy is not effective and that other interventions such as percutaneous coronary intervention (PCI) may be needed. Bruising is a possible side effect of thrombolytic therapy, but it is not an indication that therapy should be discontinued. The decrease of the ST-segment elevation indicates that thrombolysis is occurring and perfusion is returning to the injured myocardium. An increase in troponin levels is expected with reperfusion and is related to the washout of cardiac markers into the circulation as the blocked vessel is opened.

25. The nurse is caring for a patient who was admitted to the coronary care unit following an acute myocardial infarction (AMI) and percutaneous coronary intervention the previous day. Teaching for this patient would include a. when cardiac rehabilitation will begin. b. the typical emotional responses to AMI. c. information regarding discharge medications. d. the pathophysiology of coronary artery disease.

ANS: A Early after an AMI, the patient will want to know when resumption of usual activities can be expected. At this time, the patient's anxiety level or denial will interfere with good understanding of complex information such as the pathophysiology of coronary artery disease (CAD). Teaching about discharge medications should be done closer to discharge. The nurse should support the patient by decreasing anxiety rather than discussing the typical emotional responses to myocardial infarction (MI).

26. A patient who has recently started taking pravastatin (Pravachol) and niacin (Nicobid) reports the following symptoms to the nurse. Which is most important to communicate to the health care provider? a. Generalized muscle aches and pains b. Dizziness when changing positions quickly c. Nausea when taking the drugs before eating d. Flushing and pruritus after taking the medications

ANS: A Muscle aches and pains may indicate myopathy and rhabdomyolysis, which have caused acute kidney injury and death in some patients who have taken the statin medications. These symptoms indicate that the pravastatin may need to be discontinued. The other symptoms are common side effects when taking niacin, and although the nurse should follow-up with the health care provider, they do not indicate that a change in medication is needed.

27. A patient who is being admitted to the emergency department with intermittent chest pain gives the following list of medications to the nurse. Which medication has the most immediate implications for the patient's care? a. Sildenafil (Viagra) b. Furosemide (Lasix) c. Captopril (Capoten) d. Warfarin (Coumadin)

ANS: A The nurse will need to avoid giving nitrates to the patient because nitrate administration is contraindicated in patients who are using sildenafil because of the risk of severe hypotension caused by vasodilation. The other home medications also should be documented and reported to the health care provider but do not have as immediate an impact on decisions about the patient's treatment.

19. Three days after experiencing a myocardial infarction (MI), a patient who is scheduled for discharge asks for assistance with hygiene activities, saying, "I am too nervous to take care of myself." Based on this information, which nursing diagnosis is appropriate? a. Ineffective coping related to anxiety b. Activity intolerance related to weakness c. Denial related to lack of acceptance of the MI d. Disturbed personal identity related to understanding of illness

ANS: A The patient data indicate that ineffective coping after the MI caused by anxiety about the impact of the MI is a concern. The other nursing diagnoses may be appropriate for some patients after an MI, but the data for this patient do not support denial, activity intolerance, or disturbed personal identity.

A patient arrives in the emergency department complaining of chest pain that has lasted longer than 1 hour and is unrelieved by nitroglycerin. The patient's electrocardiogram reveals elevation of the ST segment. Initial cardiac troponin levels are negative. The patient is receiving oxygen via nasal cannula. Which drug should be given immediately? a. Aspirin 325 mg chewable b. Beta blocker given IV c. Ibuprofen 400 mg orally d. Morphine intravenously

ANS: A This patient shows signs of acute ST-elevation myocardial infarction (STEMI). Because cardiac troponin levels usually are not detectable until 2 to 4 hours after the onset of symptoms, treatment should begin as symptoms evolve. Chewable aspirin (ASA) should be given immediately to suppress platelet aggregation and produce an antithrombotic effect. Beta blockers are indicated but do not have to be given immediately. Ibuprofen is contraindicated. Morphine is indicated for pain management and should be administered after aspirin has been given.

21. A few days after experiencing a myocardial infarction (MI) and successful percutaneous coronary intervention, the patient states, "I just had a little chest pain. As soon as I get out of here, I'm going for my vacation as planned." Which reply would be most appropriate for the nurse to make? a. "What do you think caused your chest pain?" b. "Where are you planning to go for your vacation?" c. "Sometimes plans need to change after a heart attack." d. "Recovery from a heart attack takes at least a few weeks."

ANS: A When the patient is experiencing denial, the nurse should assist the patient in testing reality until the patient has progressed beyond this step of the emotional adjustment to MI. Asking the patient about vacation plans reinforces the patient's plan, which is not appropriate in the immediate post-MI period. Reminding the patient in denial about the MI is likely to make the patient angry and lead to distrust of the nursing staff.

Patients with a history of myocardial infarction should take which medications indefinitely? (Select all that apply.) a. ACE inhibitors b. Alteplase c. Aspirin d. Beta blockers e. Clopidogrel

ANS: A, C, D Patients who have had an MI should take ACE inhibitors, ASA, and beta blockers indefinitely to prevent recurrence and to minimize continuing cardiac remodeling. Alteplase is given during acute management, and clopidogrel is used during acute management and as an adjunct to reperfusion therapy.

A patient is admitted to the coronary care unit from the emergency department after initial management of STEMI. A primary percutaneous coronary intervention has been performed. The nurse notes an initial heart rate of 56 beats per minute and a blood pressure of 120/80 mm Hg. The patient has a history of stroke and a previous myocardial infarction. Which order will the nurse question? a. Aspirin b. Beta blocker c. Clopidogrel d. Heparin

ANS: B A beta blocker would be contraindicated in this patient, because it slows the heart, and this patient is already bradycardic. Aspirin, clopidogrel, and heparin are recommended in patients who have had a primary PCI.

33. When admitting a patient with a non-ST-segment-elevation myocardial infarction (NSTEMI) to the intensive care unit, which action should the nurse perform first? a. Obtain the blood pressure. b. Attach the cardiac monitor. c. Assess the peripheral pulses. d. Auscultate the breath sounds.

ANS: B Because dysrhythmias are the most common complication of myocardial infarction (MI), the first action should be to place the patient on a cardiac monitor. The other actions also are important and should be accomplished as quickly as possible.

39. To improve the physical activity level for a mildly obese 71-year-old patient, which action should the nurse plan to take? a. Stress that weight loss is a major benefit of increased exercise. b. Determine what kind of physical activities the patient usually enjoys. c. Tell the patient that older adults should exercise for no more than 20 minutes at a time. d. Teach the patient to include a short warm-up period at the beginning of physical activity.

ANS: B Because patients are more likely to continue physical activities that they already enjoy, the nurse will plan to ask the patient about preferred activities. The goal for older adults is 30 minutes of moderate activity on most days. Older adults should plan for a longer warm-up period. Benefits of exercises, such as improved activity tolerance, should be emphasized rather than aiming for significant weight loss in older mildly obese adults.

3. Which assessment data collected by the nurse who is admitting a patient with chest pain suggest that the pain is caused by an acute myocardial infarction (AMI)? a. The pain increases with deep breathing. b. The pain has lasted longer than 30 minutes. c. The pain is relieved after the patient takes nitroglycerin. d. The pain is reproducible when the patient raises the arms.

ANS: B Chest pain that lasts for 20 minutes or more is characteristic of AMI. Changes in pain that occur with raising the arms or with deep breathing are more typical of musculoskeletal pain or pericarditis. Stable angina is usually relieved when the patient takes nitroglycerin.

20. When caring for a patient who is recovering from a sudden cardiac death (SCD) event and has no evidence of an acute myocardial infarction (AMI), the nurse will anticipate teaching the patient that a. sudden cardiac death events rarely reoccur. b. additional diagnostic testing will be required. c. long-term anticoagulation therapy will be needed. d. limited physical activity after discharge will be needed to prevent future events.

ANS: B Diagnostic testing (e.g., stress test, Holter monitor, electrophysiologic studies, cardiac catheterization) is used to determine the possible cause of the SCD and treatment options. SCD is likely to recur. Anticoagulation therapy will not have any effect on the incidence of SCD, and SCD can occur even when the patient is resting.

A patient who is receiving reperfusion therapy has a history of heparin-induced thrombosis (HIT). The patient has a creatinine clearance of 28 mL/min. In addition to the fibrinolytic agent, which medication will the nurse expect to administer to this patient? a. Aspirin b. Bivalirudin [Angiomax] c. Clopidogrel [Plavix] d. Fondaparinux [Arixtra]

ANS: B Patients receiving a fibrinolytic medication will also need an anticoagulant to reduce the risk of thrombosis. This patient cannot receive heparin because of the history of HIT, so he or she will need either bivalirudin or fondaparinux. Bivalirudin may be used at reduced doses in patients with a creatinine clearance less than 30 mL/min, but fondaparinux is contraindicated in such patients. Antiplatelet drugs such as aspirin or clopidogrel are not used for this purpose.

10. The nurse will suspect that the patient with stable angina is experiencing a side effect of the prescribed metoprolol (Lopressor) if the a. patient is restless and agitated. b. blood pressure is 90/54 mm Hg. c. patient complains about feeling anxious. d. cardiac monitor shows a heart rate of 61 beats/minute.

ANS: B Patients taking β-adrenergic blockers should be monitored for hypotension and bradycardia. Because this class of medication inhibits the sympathetic nervous system, restlessness, agitation, hypertension, and anxiety will not be side effects.

7. After the nurse teaches the patient about the use of carvedilol (Coreg) in preventing anginal episodes, which statement by a patient indicates that the teaching has been effective? a. "Carvedilol will help my heart muscle work harder." b. "It is important not to suddenly stop taking the carvedilol." c. "I can expect to feel short of breath when taking carvedilol." d. "Carvedilol will increase the blood flow to my heart muscle."

ANS: B Patients who have been taking β-adrenergic blockers can develop intense and frequent angina if the medication is suddenly discontinued. Carvedilol (Coreg) decreases myocardial contractility. Shortness of breath that occurs when taking β-adrenergic blockers for angina may be due to bronchospasm and should be reported to the health care provider. Carvedilol works by decreasing myocardial oxygen demand, not by increasing blood flow to the coronary arteries.

A patient has undergone a primary percutaneous coronary intervention with a stent placement. The provider has ordered a daily dose of 81 mg of aspirin and clopidogrel. The patient asks the nurse how long the medications must be taken. What will the nurse tell this patient about the medication regimen? a. This drug regimen will continue indefinitely. b. The clopidogrel will be discontinued in one year and the aspirin will be given indefinitely. c. The aspirin will be discontinued in one year and the clopidogrel will be given indefinitely. d. Both drugs will be discontinued in one year.

ANS: B Patients who have undergone PCI with a stent will take ASA indefinitely along with an antiplatelet drug for one year. The clopidogrel will be discontinued in one year, but the aspirin will be given indefinitely.

9. Diltiazem (Cardizem) is ordered for a patient with newly diagnosed Prinzmetal's (variant) angina. When teaching the patient, the nurse will include the information that diltiazem will a. reduce heart palpitations. b. decrease spasm of the coronary arteries. c. increase the force of the heart contractions. d. help prevent plaque from forming in the coronary arteries.

ANS: B Prinzmetal's angina is caused by coronary artery spasm. Calcium channel blockers (e.g., diltiazem, amlodipine [Norvasc

23. A patient who is recovering from an acute myocardial infarction (AMI) asks the nurse about when sexual intercourse can be resumed. Which response by the nurse is best? a. "Most patients are able to enjoy intercourse without any complications." b. "Sexual activity uses about as much energy as climbing two flights of stairs." c. "The doctor will provide sexual guidelines when your heart is strong enough." d. "Holding and cuddling are good ways to maintain intimacy after a heart attack."

ANS: B Sexual activity places about as much physical stress on the cardiovascular system as most moderate-energy activities such as climbing two flights of stairs. The other responses do not directly address the patient's question or may not be accurate for this patient.

28. Which assessment finding by the nurse caring for a patient who has had coronary artery bypass grafting using a right radial artery graft is most important to communicate to the health care provider? a. Complaints of incisional chest pain b. Pallor and weakness of the right hand c. Fine crackles heard at both lung bases d. Redness on both sides of the sternal incision

ANS: B The changes in the right hand indicate compromised blood flow, which requires immediate evaluation and actions such as prescribed calcium channel blockers or surgery. The other changes are expected and/or require nursing interventions.

13. When titrating IV nitroglycerin (Tridil) for a patient with a myocardial infarction (MI), which action will the nurse take to evaluate the effectiveness of the medication? a. Monitor heart rate. b. Ask about chest pain. c. Check blood pressure. d. Observe for dysrhythmias.

ANS: B The goal of IV nitroglycerin administration in MI is relief of chest pain by improving the balance between myocardial oxygen supply and demand. The nurse also will monitor heart rate and blood pressure (BP) and observe for dysrhythmias, but these parameters will not indicate whether the medication is effective.

40. Which patient at the cardiovascular clinic requires the most immediate action by the nurse? a. Patient with type 2 diabetes whose current blood glucose level is 145 mg/dL b. Patient with stable angina whose chest pain has recently increased in frequency c. Patient with familial hypercholesterolemia and a total cholesterol of 465 mg/dL d. Patient with chronic hypertension whose blood pressure today is 172/98 mm Hg

ANS: B The history of more frequent chest pain suggests that the patient may have unstable angina, which is part of the acute coronary syndrome spectrum. This will require rapid implementation of actions such as cardiac catheterization and possible percutaneous coronary intervention. The data about the other patients suggest that their conditions are stable.

22. When evaluating the effectiveness of preoperative teaching with a patient scheduled for coronary artery bypass graft (CABG) surgery using the internal mammary artery, the nurse determines that additional teaching is needed when the patient says which of the following? a. "They will circulate my blood with a machine during the surgery." b. "I will have small incisions in my leg where they will remove the vein." c. "They will use an artery near my heart to go around the area that is blocked." d. "I will need to take an aspirin every day after the surgery to keep the graft open."

ANS: B When the internal mammary artery is used there is no need to have a saphenous vein removed from the leg. The other statements by the patient are accurate and indicate that the teaching has been effective.

15. Following an acute myocardial infarction (AMI), a patient ambulates in the hospital hallway. When the nurse is evaluating the patient's response to the activity, which assessment data would indicate that the exercise level should be decreased? a. Blood pressure (BP) changes from 118/60 to 126/68 mm Hg. b. Oxygen saturation drops from 99% to 95%. c. Heart rate increases from 66 to 92 beats/minute. d. Respiratory rate goes from 14 to 20 breaths/minute.

ANS: C A change in heart rate of more than 20 beats over the resting heart rate indicates that the patient should stop and rest. The increases in BP and respiratory rate, and the slight decrease in oxygen saturation, are normal responses to exercise.

32. A patient admitted to the coronary care unit (CCU) with an ST-segment-elevation myocardial infarction (STEMI) is restless and anxious. The blood pressure is 86/40 and heart rate is 123. Based on this information, which nursing diagnosis is a priority for the patient? a. Acute pain related to myocardial infarction b. Anxiety related to perceived threat of death c. Stress overload related to acute change in health d. Decreased cardiac output related to cardiogenic shock

ANS: C All the nursing diagnoses may be appropriate for this patient, but the hypotension and tachycardia indicate decreased cardiac output and shock from the damaged myocardium. This will result in decreased perfusion to all vital organs (e.g., brain, kidney, heart) and is a priority.

12. Heparin is ordered for a patient with a non-ST-segment-elevation myocardial infarction (NSTEMI). What is the purpose of the heparin? a. Heparin enhances platelet aggregation. b. Heparin decreases coronary artery plaque size. c. Heparin prevents the development of new clots in the coronary arteries. d. Heparin dissolves clots that are blocking blood flow in the coronary arteries.

ANS: C Heparin helps prevent the conversion of fibrinogen to fibrin and decreases coronary artery thrombosis. It does not change coronary artery plaque, dissolve already formed clots, or enhance platelet aggregation.

2. Which nursing intervention will be most effective when assisting the patient with coronary artery disease (CAD) to make appropriate dietary changes? a. Give the patient a list of low-sodium, low-cholesterol foods that should be included in the diet. b. Emphasize the increased risk for heart problems unless the patient makes the dietary changes. c. Help the patient modify favorite high-fat recipes by using monosaturated oils when possible. d. Inform the patient that a diet containing no saturated fat and minimal salt will be necessary.

ANS: C Lifestyle changes are more likely to be successful when consideration is given to the patient's values and preferences. The highest percentage of calories from fat should come from monosaturated fats. Although low-sodium and low-cholesterol foods are appropriate, providing the patient with a list alone is not likely to be successful in making dietary changes. Completely removing saturated fat from the diet is not a realistic expectation. Up to 7% of calories in the therapeutic lifestyle changes (TLC) diet can come from saturated fat. Telling the patient about the increased risk without assisting further with strategies for dietary change is unlikely to be successful.

A patient has undergone a PCI, and the provider orders clopidogrel to be given for 12 months, along with an ACE inhibitor and heparin. What will the nurse do? a. Question the need for heparin. b. Request an order for a beta blocker. c. Request an order for aspirin. d. Suggest ordering clopidogrel for 14 days.

ANS: C Patients who have undergone a PCI should receive heparin, ASA, and a fibrinolytic; therefore, this patient needs ASA added to the drug regimen. Heparin should be given before, during, and for at least 48 to 72 hours after the procedure. Beta blockers are not necessarily indicated. Clopidogrel should be given at least 12 months after the procedure.

A nurse is evaluating a patient admitted to the emergency department with an evolving STEMI for possible administration of thrombolytic therapy. Which information, identified during history taking, would contraindicate this type of therapy? a. The patient just completed her last menstrual cycle. b. The patient states that the chest pain started 1 hour ago. c. The patient has a history of a small cerebral aneurysm. d. The patient has hypertension that is well controlled by diuretic therapy.

ANS: C Patients with a history of CVA should not receive fibrinolytic therapy. This patient has had a known cerebral aneurysm. Active internal bleeding is a contraindication for thrombolysis except for menses, but the patient has indicated she has completed her last cycle. Fibrinolytic therapy should be administered for chest pain that has been present for no longer than 12 hours. Poorly controlled or severe hypertension is a relative contraindication. Thrombolytics can be administered with caution.

A nurse is discussing fibrinolytic therapy for the acute phase of STEMI management with a group of nursing students. Which statement by a student indicates understanding of this therapy? a. "Fibrinolytics are effective when the first dose is given up to 24 hours after symptom onset." b. "Fibrinolytics should be given once cardiac troponins reveal the presence of STEMI." c. "Fibrinolytics should be used with caution in patients with a history of cerebrovascular accident." d. "Patients should receive either an anticoagulant or an antiplatelet agent with a fibrinolytic drug."

ANS: C Patients with a history of cerebrovascular accident (CVA) should not receive fibrinolytic agents because of the increased risk of intracranial hemorrhage. Fibrinolytics are most effective when given within 30 minutes of arrival in the emergency department. Because cardiac troponins are not detectable until 2 to 4 hours after the onset of symptoms, fibrinolytics should be administered before these laboratory values are available. Patients receiving fibrinolytics should receive both an anticoagulant and an antiplatelet drug.

16. During the administration of the thrombolytic agent to a patient with an acute myocardial infarction (AMI), the nurse should stop the drug infusion if the patient experiences a. bleeding from the gums. b. increase in blood pressure. c. a decrease in level of consciousness. d. a nonsustained episode of ventricular tachycardia.

ANS: C The change in level of consciousness indicates that the patient may be experiencing intracranial bleeding, a possible complication of thrombolytic therapy. Some bleeding of the gums is an expected side effect of the therapy but not an indication to stop infusion of the thrombolytic medication. A decrease in blood pressure could indicate internal bleeding. A nonsustained episode of ventricular tachycardia is a common reperfusion dysrhythmia and may indicate that the therapy is effective.

35. The nurse obtains the following data when assessing a patient who experienced an ST-segment-elevation myocardial infarction (STEMI) 2 days previously. Which information is most important to report to the health care provider? a. The troponin level is elevated. b. The patient denies ever having a heart attack. c. Bilateral crackles are auscultated in the mid-lower lobes. d. The patient has occasional premature atrial contractions (PACs).

ANS: C The crackles indicate that the patient may be developing heart failure, a possible complication of myocardial infarction (MI). The health care provider may need to order medications such as diuretics or angiotensin-converting enzyme (ACE) inhibitors for the patient. Elevation in troponin level at this time is expected. PACs are not life-threatening dysrhythmias. Denial is a common response in the immediate period after the MI.

5. After the nurse has finished teaching a patient about the use of sublingual nitroglycerin (Nitrostat), which patient statement indicates that the teaching has been effective? a. "I can expect some nausea as a side effect of nitroglycerin." b. "I should only take the nitroglycerin if I start to have chest pain." c. "I will call an ambulance if I still have pain after taking 3 nitroglycerin 5 minutes apart." d. "Nitroglycerin helps prevent a clot from forming and blocking blood flow to my heart."

ANS: C The emergency medical services (EMS) system should be activated when chest pain or other symptoms are not completely relieved after 3 sublingual nitroglycerin tablets taken 5 minutes apart. Nitroglycerin can be taken to prevent chest pain or other symptoms from developing (e.g., before intercourse). Gastric upset (e.g., nausea) is not an expected side effect of nitroglycerin. Nitroglycerin does not impact the underlying pathophysiology of coronary artery atherosclerosis.

42. After reviewing information shown in the accompanying figure from the medical records of a 43-year-old, which risk factor modification for coronary artery disease should the nurse include in patient teaching? a. Importance of daily physical activity b. Effect of weight loss on blood pressure c. Dietary changes to improve lipid levels d. Ongoing cardiac risk associated with history of tobacco use

ANS: C The patient has an elevated low-density lipoprotein (LDL) cholesterol and low high-density lipoprotein (HDL) cholesterol, which will increase the risk of coronary artery disease. Although the blood pressure is in the prehypertensive range, the patient's waist circumference and body mass index (BMI) indicate an appropriate body weight. The risk for coronary artery disease a year after quitting smoking is the same as a nonsmoker. The patient's occupation indicates that daily activity is at the levels suggested by national guidelines.

30. Which electrocardiographic (ECG) change is most important for the nurse to report to the health care provider when caring for a patient with chest pain? a. Inverted P wave b. Sinus tachycardia c. ST-segment elevation d. First-degree atrioventricular block

ANS: C The patient is likely to be experiencing an ST-segment-elevation myocardial infarction (STEMI). Immediate therapy with percutaneous coronary intervention (PCI) or thrombolytic medication is indicated to minimize myocardial damage. The other ECG changes may also suggest a need for therapy, but not as rapidly.

18. In preparation for discharge, the nurse teaches a patient with chronic stable angina how to use the prescribed short-acting and long-acting nitrates. Which patient statement indicates that the teaching has been effective? a. "I will check my pulse rate before I take any nitroglycerin tablets." b. "I will put the nitroglycerin patch on as soon as I get any chest pain." c. "I will stop what I am doing and sit down before I put the nitroglycerin under my tongue." d. "I will be sure to remove the nitroglycerin patch before taking any sublingual nitroglycerin."

ANS: C The patient should sit down before taking the nitroglycerin to decrease cardiac workload and prevent orthostatic hypotension. Transdermal nitrates are used prophylactically rather than to treat acute pain and can be used concurrently with sublingual nitroglycerin. Although the nurse should check blood pressure before giving nitroglycerin, patients do not need to check the pulse rate before taking nitrates.

17. A patient is recovering from a myocardial infarction (MI) and develops chest pain on day 3 that increases when taking a deep breath and is relieved by leaning forward. Which action should the nurse take next? a. Assess the feet for pedal edema. b. Palpate the radial pulses bilaterally. c. Auscultate for a pericardial friction rub. d. Check the heart monitor for dysrhythmias.

ANS: C The patient's symptoms are consistent with the development of pericarditis, a possible complication of MI. The other assessments listed are not consistent with the description of the patient's symptoms.

37. A patient who has chest pain is admitted to the emergency department (ED) and all of the following are ordered. Which one should the nurse arrange to be completed first? a. Chest x-ray b. Troponin level c. Electrocardiogram (ECG) d. Insertion of a peripheral IV

ANS: C The priority for the patient is to determine whether an acute myocardial infarction (AMI) is occurring so that reperfusion therapy can begin as quickly as possible. ECG changes occur very rapidly after coronary artery occlusion, and an ECG should be obtained as soon as possible. Troponin levels will increase after about 3 hours. Data from the chest x-ray may impact the patient's care but are not helpful in determining whether the patient is experiencing a myocardial infarction (MI). Peripheral access will be needed but not before the ECG.

41. A patient with diabetes mellitus and chronic stable angina has a new order for captopril (Capoten). The nurse should teach the patient that the primary purpose of captopril is to a. lower heart rate. b. control blood glucose levels. c. prevent changes in heart muscle. d. reduce the frequency of chest pain.

ANS: C The purpose for angiotensin-converting enzyme (ACE) inhibitors in patients with chronic stable angina who are at high risk for a cardiac event is to decrease ventricular remodeling. ACE inhibitors do not directly impact angina frequency, blood glucose, or heart rate.

14. A patient with ST-segment elevation in three contiguous electrocardiographic (ECG) leads is admitted to the emergency department (ED) and diagnosed as having an ST-segment-elevation myocardial infarction (STEMI). Which question should the nurse ask to determine whether the patient is a candidate for thrombolytic therapy? a. "Do you have any allergies?" b. "Do you take aspirin on a daily basis?" c. "What time did your chest pain begin?" d. "Can you rate your chest pain using a 0 to 10 scale?"

ANS: C Thrombolytic therapy should be started within 6 hours of the onset of the myocardial infarction (MI), so the time at which the chest pain started is a major determinant of the appropriateness of this treatment. The other information will also be needed, but it will not be a factor in the decision about thrombolytic therapy.

6. Which statement made by a patient with coronary artery disease after the nurse has completed teaching about therapeutic lifestyle changes (TLC) diet indicates that further teaching is needed? a. "I will switch from whole milk to 1% milk." b. "I like salmon and I will plan to eat it more often." c. "I can have a glass of wine with dinner if I want one." d. "I will miss being able to eat peanut butter sandwiches."

ANS: D Although only 30% of the daily calories should come from fats, most of the fat in the TLC diet should come from monosaturated fats such as are found in nuts, olive oil, and canola oil. The patient can include peanut butter sandwiches as part of the TLC diet. The other patient comments indicate a good understanding of the TLC diet.

1. When developing a teaching plan for a 61-year-old man with the following risk factors for coronary artery disease (CAD), the nurse should focus on the a. family history of coronary artery disease. b. increased risk associated with the patient's gender. c. increased risk of cardiovascular disease as people age. d. elevation of the patient's low-density lipoprotein (LDL) level.

ANS: D Because family history, gender, and age are nonmodifiable risk factors, the nurse should focus on the patient's LDL level. Decreases in LDL will help reduce the patient's risk for developing CAD.

11. Nadolol (Corgard) is prescribed for a patient with chronic stable angina and left ventricular dysfunction. To determine whether the drug is effective, the nurse will monitor for a. decreased blood pressure and heart rate. b. fewer complaints of having cold hands and feet. c. improvement in the strength of the distal pulses. d. the ability to do daily activities without chest pain.

ANS: D Because the medication is ordered to improve the patient's angina, effectiveness is indicated if the patient is able to accomplish daily activities without chest pain. Blood pressure and heart rate may decrease, but these data do not indicate that the goal of decreased angina has been met. The noncardioselective β-adrenergic blockers can cause peripheral vasoconstriction, so the nurse would not expect an improvement in distal pulse quality or skin temperature.

4. Which information given by a patient admitted with chronic stable angina will help the nurse confirm this diagnosis? a. The patient states that the pain "wakes me up at night." b. The patient rates the pain at a level 3 to 5 (0 to 10 scale). c. The patient states that the pain has increased in frequency over the last week. d. The patient states that the pain "goes away" with one sublingual nitroglycerin tablet.

ANS: D Chronic stable angina is typically relieved by rest or nitroglycerin administration. The level of pain is not a consistent indicator of the type of angina. Pain occurring at rest or with increased frequency is typical of unstable angina.

A patient in the emergency department has severe chest pain. The nurse administers morphine intravenously. The patient asks the nurse why morphine is given. Which response by the nurse is correct? a. "Morphine helps by reducing anxiety and relieving pain." b. "Morphine helps by reducing pain and dissolving clots." c. "Morphine helps by relieving pain and lowering blood pressure." d. "Morphine helps by relieving pain and reducing the cardiac oxygen demand."

ANS: D IV morphine is the treatment of choice for STEMI-associated pain. Besides relieving pain, it promotes vasodilation and reduces cardiac preload, which lowers the cardiac oxygen demand. It does not reduce anxiety, dissolve clots, or lower blood pressure.

36. A patient had a non-ST-segment-elevation myocardial infarction (NSTEMI) 3 days ago. Which nursing intervention included in the plan of care is most appropriate for the registered nurse (RN) to delegate to an experienced licensed practical/vocational nurse (LPN/LVN)? a. Evaluation of the patient's response to walking in the hallway b. Completion of the referral form for a home health nurse follow-up c. Education of the patient about the pathophysiology of heart disease d. Reinforcement of teaching about the purpose of prescribed medications

ANS: D LPN/LVN education and scope of practice include reinforcing education that has previously been done by the RN. Evaluating the patient response to exercise after a NSTEMI requires more education and should be done by the RN. Teaching and discharge planning/ documentation are higher level skills that require RN education and scope of practice.

A patient diagnosed with STEMI is about to undergo a primary percutaneous coronary intervention (PCI). Which combination of pharmacotherapeutic agents will be given to augment this procedure? a. Beta blocker and nitroglycerin b. Abciximab and a fibrinolytic drug c. Angiotensin-converting enzyme (ACE) inhibitor and aspirin d. Heparin, aspirin, and clopidogrel

ANS: D Patients undergoing a primary PCI should receive heparin intravenously combined with aspirin and either clopidogrel or prasugrel. Abciximab and fibrinolytic drugs are not indicated. Beta blockers and nitroglycerin do not prevent thromboses. ACE inhibitors do not prevent thromboses

43. After reviewing a patient's history, vital signs, physical assessment, and laboratory data, which information shown in the accompanying figure is most important for the nurse to communicate to the health care provider? a. Q waves on ECG b. Elevated troponin levels c. Fever and hyperglycemia d. Tachypnea and crackles in lungs

ANS: D Pulmonary congestion and tachypnea suggest that the patient may be developing heart failure, a complication of myocardial infarction (MI). Mild fever and hyperglycemia are common after MI because of the inflammatory process that occurs with tissue necrosis. Troponin levels will be elevated for several days after MI. Q waves often develop with ST-segment-elevation MI.

24. A patient with hyperlipidemia has a new order for colesevelam (Welchol). Which nursing action is most appropriate when giving the medication? a. Have the patient take this medication with an aspirin. b. Administer the medication at the patient's usual bedtime. c. Have the patient take the colesevelam with a sip of water. d. Give the patient's other medications 2 hours after the colesevelam.

ANS: D The bile acid sequestrants interfere with the absorption of many other drugs, and giving other medications at the same time should be avoided. Taking an aspirin concurrently with the colesevelam may increase the incidence of gastrointestinal side effects such as heartburn. An increased fluid intake is encouraged for patients taking the bile acid sequestrants to reduce the risk for constipation. For maximum effect, colesevelam should be administered with meals.

31. When caring for a patient with acute coronary syndrome who has returned to the coronary care unit after having angioplasty with stent placement, the nurse obtains the following assessment data. Which data indicate the need for immediate action by the nurse? a. Heart rate 102 beats/min b. Pedal pulses 1+ bilaterally c. Blood pressure 103/54 mm Hg d. Chest pain level 7 on a 0 to 10 point scale

ANS: D The patient's chest pain indicates that restenosis of the coronary artery may be occurring and requires immediate actions, such as administration of oxygen and nitroglycerin, by the nurse. The other information indicates a need for ongoing assessments by the nurse.

38. After receiving change-of-shift report about the following four patients, which patient should the nurse assess first? a. 39-year-old with pericarditis who is complaining of sharp, stabbing chest pain b. 56-year-old with variant angina who is to receive a dose of nifedipine (Procardia) c. 65-year-old who had a myocardial infarction (MI) 4 days ago and is anxious about the planned discharge d. 59-year-old with unstable angina who has just returned to the unit after having a percutaneous coronary intervention (PCI)

ANS: D This patient is at risk for bleeding from the arterial access site for the PCI, so the nurse should assess the patient's blood pressure, pulse, and the access site immediately. The other patients should also be assessed as quickly as possible, but assessment of this patient has the highest priority.

A patient who is recovering from a STEMI 3 months prior is in the clinic for a follow-up evaluation. The patient is taking 81 mg of aspirin, a beta blocker, and an ACE inhibitor daily and uses nitroglycerine as needed for angina. The patient's BMI is 24.5 kg/m2, and serum LDL is 150 mg/dL. The patient has a blood pressure of 135/80 mm Hg. What will the nurse expect the provider to order for this patient? a. An antihypertensive medication b. Counseling about a weight loss diet c. Discontinuing the ACE inhibitor d. High-dose statin therapy

ANS: D To help prevent recurrence of MI in patients post-STEMI, a high-dose statin should be given to patients with elevated cholesterol. This patient's blood pressure and BMI are normal, so antihypertensives and a weight loss diet are not recommended. The three drugs should be continued indefinitely.

8. A patient who has had chest pain for several hours is admitted with a diagnosis of rule out acute myocardial infarction (AMI). Which laboratory test should the nurse monitor to help determine whether the patient has had an AMI? a. Myoglobin b. Homocysteine c. C-reactive protein d. Cardiac-specific troponin

ANS: D Troponin levels increase about 4 to 6 hours after the onset of myocardial infarction (MI) and are highly specific indicators for MI. Myoglobin is released within 2 hours of MI, but it lacks specificity and its use is limited. The other laboratory data are useful in determining the patient's risk for developing coronary artery disease (CAD) but are not helpful in determining whether an acute MI is in progress.

A client with angina pectoris must learn how to reduce risk factors that exacerbate this condition. When developing the client's care plan, which expected outcome should a nurse include? a) "Client will verbalize the intention to stop smoking." b) "Client will verbalize an understanding of the need to call the physician if acute pain lasts more than 2 hours." c) "Client will verbalize the intention to avoid exercise." d) "Client will verbalize an understanding of the need to restrict dietary fat, fiber, and cholesterol."

a) "Client will verbalize the intention to stop smoking." A client with angina pectoris should stop smoking at once because smoking increases the blood carboxyhemoglobin level; this increase, in turn, reduces the heart's oxygen supply and may induce angina. The client must seek immediate medical attention if chest pain doesn't subside after three nitroglycerin doses taken 5 minutes apart; serious myocardial damage or even sudden death may occur if chest pain persists for 2 hours. To improve coronary circulation and promote weight management, the client should get regular daily exercise. The client should eat plenty of fiber, which may decrease serum cholesterol and triglyceride levels and minimize hypertension, in turn reducing the risk for atherosclerosis (which plays a role in angina).

Heparin therapy is usually considered therapeutic when the patient's activated partial thromboplastin time (aPTT) is how many times normal? a) 2 to 2.5 b) .5 to 1 c) 2.5 to 3 d) .25 to .75

a) 2 to 2.5 The amount of heparin administered is based on aPTT results, which should be obtained in follow-up to any alteration of dosage. The patient's aPTT value would have to be greater than .5 to 1 times normal to be considered therapeutic. An aPTT value that is 2.5 to 3 times normal would be too high to be considered therapeutic. The patient's aPTT value would have to be greater than .25 to .75 times normal to be considered therapeutic.

A patient asks the nurse how long he will have to wait after taking nitroglycerin before experiencing pain relief. What is the best answer by the nurse? a) 3 minutes b) 15 minutes c) 60 minutes d) 30 minutes

a) 3 minutes Nitroglycerin may be given by several routes: sublingual tablet or spray, oral capsule, topical agent, and intravenous (IV) administration. Sublingual nitroglycerin is generally placed under the tongue or in the cheek (buccal pouch) and ideally alleviates the pain of ischemia within 3 minutes.

The nurse has been asked to explain the cause of angina pain to a patient's family. Choose the best statement. The pain is due to: a) A lack of oxygen in the heart muscle that causes the death of cells. b) Complete closure of an artery. c) Incomplete blockage of a major coronary artery. d) A destroyed part of the heart muscle.

a) A lack of oxygen in the heart muscle that causes the death of cells. Impeded blood flow, due to blockage in a coronary artery, deprives the cardiac muscle cells of oxygen thus leading to a condition known as ischemia.

A nurse is teaching about risk factors that increase the probability of heart disease to a community group. Which of the following risk factors will the nurse include? Choose all that apply. a) African-American descent b) Family history of coronary heart disease c) Elevated C-reactive protein d) Body mass index (BMI) of 23 e) Age greater than 45 years for men

a) African-American descent b) Family history of coronary heart disease c) Elevated C-reactive protein e) Age greater than 45 years for men Risk factors for coronary heart disease (CHD) include family history of CHD, age older than 45 years for men and 65 years for women, African-American race, BMI of 25 or greater, and elevated C-reactive protein.

A 65-year-old male client complains of pain and cramping in his thigh when climbing the stairs and numbness in his legs after exertion. The nurse anticipates the physician will perform which of the following diagnostic tests right in the office to determine PAD? a) Ankle-brachial index b) Exercise electrocardiography c) Photoplethysmography d) Electron beam computed tomography

a) Ankle-brachial index The client's symptoms indicate he may have peripheral artery disease (PAD). The ankle-brachial index is a simple, noninvasive test used for its diagnosis. An exercise electrocardiography may be ordered for a client with possible CAD. An EBCT is a radiologic test that produces x-rays of the coronary arteries using an electron beam. It is used to diagnose for CAD. Clients with suspected venous insufficiency will undergo photoplethysmography, a diagnostic test that measures light that is not absorbed by hemoglobin and consequently is reflected back to the machine.

A 23-year-old female client has been diagnosed with Raynaud's disease. The nurse teaches the client which of the following self-care strategies to minimize risks associated with this disease? Select all that apply. a) Avoid over-the-counter decongestants and cold remedies. b) Wear gloves to protect hands from injury when performing tasks. c) Refrain from going outdoors in cold weather. d) Limit activities that place stress on the ulnar nerve. e) Do not smoke or stop smoking.

a) Avoid over-the-counter decongestants and cold remedies. b) Wear gloves to protect hands from injury when performing tasks. e) Do not smoke or stop smoking. The nurse instructs clients with Raynaud's disease to quit smoking, avoid over-the-counter decongestants, cold remedies, and drugs for symptomatic relief of hay fever because of their vasoconstrictive qualities, protect hands and feet from injury, and wear warm socks and mittens when going outdoors in the cold weather.

The nurse is caring for a patient who was admitted to the telemetry unit with a diagnosis of rule/out acute MI. The patient's chest pain began 3 hours ago. Which of the following laboratory tests would be most helpful in confirming the diagnosis of a current MI? a) Creatinine kinase-myoglobin (CK-MB) level b) Troponin C level c) Myoglobin level d) CK-MM

a) Creatinine kinase-myoglobin (CK-MB) level Elevated CK-MB assessment by mass assay is an indicator of acute MI; the levels begin to increase within a few hours and peak within 24 hours of an MI. If the area is reperfused (due to thrombotic therapy or PCI), it peaks earlier. CK-MM (skeletal muscle) is not an indicator of cardiac muscle damage. There are three isomers of troponin: C, I, and T. Troponin I and T are specific for cardiac muscle, and these biomarkers are currently recognized as reliable and critical markers of myocardial injury. An increase in myoglobin is not very specific in indicating an acute cardiac event; however, negative results are an excellent parameter for ruling out an acute MI.

Understanding atherosclerosis, the nurse identifies which of the following to be both a risk factor for the development of the disorder and an outcome? a) Hypertension b) Hyperlipidemia c) Obesity d) Glucose intolerance

a) Hypertension Increases in diastolic and systolic blood pressure are associated with an increased incidence of atherosclerosis, often an inherited factor. Elevation of blood pressure results when the vessels cannot relax and impairs the ability of the artery to dilate. Hyperlipidemia, diabetes, and obesity are all risk factors for atherosclerosis but do not result from the disorder.

A nurse completed a physical exam for an insurance company. The nurse noted a cluster of abnormalities that she knew was considered a major risk factor for coronary artery disease. Choose that condition. a) Metabolic syndrome b) Diabetes mellitus c) Hypolipidemia d) Congestive heart failure

a) Metabolic syndrome Metabolic syndrome includes three of six conditions that are recognized as a major risk factor for CAD. Insulin resistance is part of the syndrome but the patient may not yet have diabetes.

Upon discharge from the hospital, patients diagnosed with a myocardial infarction (MI) must be placed on all of the following medications except: a) Morphine IV b) Angiotensin-converting enzyme (ACE) inhibitor c) Aspirin d) Statin

a) Morphine IV Upon patient discharge, there needs to be documentation that the patient was discharged on a statin, an ACE or angiotensin receptor blocking agent (ARB), and aspirin. Morphine IV is used for these patients to reduce pain and anxiety. The patient would not be discharged with IV morphine.

While receiving a heparin infusion to treat deep vein thrombosis, a client reports that his gums bleed when he brushes his teeth. What should the nurse do first? a) Notify the physician. b) Administer a coumarin derivative, as ordered, to counteract heparin. c) Reassure the client that bleeding gums are a normal effect of heparin. d) Stop the heparin infusion immediately.

a) Notify the physician. Because heparin can cause bleeding gums that may indicate excessive anticoagulation, the nurse should notify the physician, who will evaluate the client's condition. The physician should order laboratory tests such as partial thromboplastin time before concluding that the client's bleeding is significant. The ordered heparin dose may be therapeutic rather than excessive, so the nurse shouldn't discontinue the heparin infusion unless the physician orders this after evaluating the client. Protamine sulfate, not a coumarin derivative, is given to counteract heparin. Heparin doesn't normally cause bleeding gums.

Which nursing actions would be of greatest importance in the management of a client preparing for angioplasty? a) Withhold anticoagulant therapy. b) Remove hair from skin insertion sites. c) Inform client of diagnostic tests. d) Assess distal pulses.

a) Withhold anticoagulant therapy. The nurse knows to withhold the anticoagulant therapy to decrease chance of hemorrhage during the procedure. The nurse does inform the client of diagnostic test, will assess pulses, and prep the skin prior to the angioplasty, but this is not the most important action to be taken.

Patients who are taking beta-adrenergic blocking agents should be cautioned not to stop taking their medications abruptly because which of the following may occur? a) Worsening angina b) Internal bleeding c) Thrombocytopenia d) Formation of blood clots

a) Worsening angina Patients taking beta blockers are cautioned not to stop taking them abruptly because angina may worsen and myocardial infarction may develop. Beta blockers do not cause the formation of blood clots, internal bleeding, or thrombocytopenia.

A client with severe angina pectoris and electrocardiogram changes is seen by a physician in the emergency department. In terms of serum testing, it's most important for the physician to order cardiac: a) troponin. b) lactate dehydrogenase. c) myoglobin. d) creatine kinase.

a) troponin. This client exhibits signs of myocardial infarction (MI), and the most accurate serum determinant of an MI is troponin level. Creatine kinase, lactate dehydrogenase and myoglobin tests can show evidence of muscle injury, but they're less specific indicators of myocardial damage than troponin.

A client, who has undergone a percutaneous transluminal coronary angioplasty (PTCA), has received discharge instructions. Which statement by the client would indicate the need for further teaching by the nurse? a) "I should expect bruising at the catheter site for up to 3 weeks." b) "I should expect a low-grade fever and swelling at the site for the next week." c) "I should avoid taking a tub bath until my catheter site heals." d) "I should avoid prolonged sitting."

b) "I should expect a low-grade fever and swelling at the site for the next week." Fever and swelling at the site are signs of infection and should be reported to the physician. Showers should be taken until the insertion site is healed. Prolonged sitting can result in thrombosis formation. Bruising at the insertion site is common and may take from 1 to 3 weeks to resolve.

A client is ordered a nitroglycerine transdermal patch for treatment of CAD and asks the nurse why the patch is removed at bedtime. Which is the best response by the nurse? a) "Contact dermatitis and skin irritations are common when the patch remains on all day." b) "Removing the patch at night prevents drug tolerance while keeping the benefits." c) "Nitroglycerine causes headaches, but removing the patch decreases the incidence." d) "You do not need the effects of nitroglycerine while you sleep."

b) "Removing the patch at night prevents drug tolerance while keeping the benefits." Tolerance to antiangina effects of nitrates can occur when taking these drugs for long periods of time. Therefore, to prevent tolerance and maintain benefits, it is a common regime to remove transdermal patches at night. Common adverse effects of nitroglycerine are headaches and contact dermatitis but not the reason for removing the patch at night. It is true that while you rest, there is less demand on the heart but not the primary reason for removing the patch.

A nurse is reevaluating a client receiving IV fibrinolytic therapy. Which of the following patient findings requires immediate intervention by the nurse? a) Minimal oozing of blood from the IV site b) Altered level of consciousness c) Chest pain: 2 of 10 (1-to-10 pain scale) d) Presence of reperfusion dysrhythmias

b) Altered level of consciousness A patient receiving fibrinolytic therapy is at risk for complications associated with bleeding. Altered level of consciousness may indicate hypoxia and intracranial bleeding and the infusion should be discontinued immediately. Minimal bleeding requires manual pressure. Reperfusion dysrhythmias are an expected finding. A chest pain score of 2 is low, and indicates the patient's chest pain is subsiding, an expected outcome of this therapy.

Which of the following methods to induce hemostasis after sheath removal post percutaneous transluminal coronary angioplasty (PTCA) is the least effective? a) Application of a vascular closure device, such as Angioseal, VasoSeal, Duett, or Syvek patch b) Application of a sandbag to the area c) Direct manual pressure d) Application of a pneumatic compression device (eg, Fem-Stop)

b) Application of a sandbag to the area Several nursing interventions frequently used as part of the standard of care, such as applying a sandbag to the sheath insertion site, have not been shown to be effective in reducing the incidence of bleeding. Application of a vascular closure device has been demonstrated to be very effective. Direct manual pressure to the sheath introduction site has been demonstrated to be effective and was the first method used to induce hemostasis post PTCA. Application of a pneumatic compression device post PTCA has been demonstrated to be effective.

A patient has had cardiac surgery and is being monitored in the intensive care unit (ICU). What complication should the nurse monitor for that is associated with an alteration in preload? a) Hypertension b) Cardiac tamponade c) Elevated central venous pressure d) Hypothermia

b) Cardiac tamponade Preload alterations occur when too little blood volume returns to the heart as a result of persistent bleeding and hypovolemia. Excessive postoperative bleeding can lead to decreased intravascular volume, hypotension, and low cardiac output. Bleeding problems are common after cardiac surgery because of the effects of cardiopulmonary bypass, trauma from the surgery, and anticoagulation. Preload can also decrease if there is a collection of fluid and blood in the pericardium (cardiac tamponade), which impedes cardiac filling. Cardiac output is also altered if too much volume returns to the heart, causing fluid overload.

A patient diagnosed with a myocardial infarction (MI) has begun an active rehabilitation program. The nurse recognizes an overall goal of rehabilitation for a patient who has had an MI includes which of the following? a) Returning the patient to work and a preillness lifestyle b) Improvement of the quality of life c) Prevention of another cardiac event d) Limiting the effects and progression of atherosclerosis

b) Improvement of the quality of life Overall, cardiac rehabilitation is a complete program dedicated to extending and improving quality of life.

A client with chest pain doesn't respond to nitroglycerin. When he's admitted to the emergency department, the health care team obtains an electrocardiogram and administers I.V. morphine. The physician also considers administering alteplase (Activase). This thrombolytic agent must be administered how soon after onset of myocardial infarction (MI) symptoms? a) Within 5 to 7 days b) Within 6 hours c) Within 12 hours d) Within 24 to 48 hours

b) Within 6 hours For the best chance of salvaging the client's myocardium, a thrombolytic agent must be administered within 6 hours after onset of chest pain or other signs or symptoms of MI. Sudden death is most likely to occur within the first 24 hours after an MI. Physicians initiate I.V. heparin therapy after administration of a thrombolytic agent; it usually continues for 5 to 7 days.

The nurse is reviewing the results of a total cholesterol level for a patient who has been taking simvastatin (Zocor). What results display the effectiveness of the medication? a) 250-275 mg/dL b) 210-240 mg/dL c) 160-190 mg/dL d) 280-300 mg/dL

c) 160-190 mg/dL Simvastatin (Zocor) is a statin frequently given as initial therapy for significantly elevated cholesterol and low-density lipoprotein levels. Normal total cholesterol is less than 200 mg/dL.

Following a percutaneous transluminal coronary angioplasty, a client is monitored in the postprocedure unit. The client's heparin infusion was stopped 2 hours earlier. There is no evidence of bleeding or hematoma at the insertion site, and the pressure device is removed. The nurse should plan to remove the femoral sheath when the partial thromboplastin time (PTT) is: a) 125 seconds or less. b) 100 seconds or less. c) 50 seconds or less. d) 75 seconds or less.

c) 50 seconds or less. Heparin causes an elevation of the PTT and, thereby, increases the risk for bleeding. With a large cannulation such as a sheath used for angioplasty, the PTT should be 50 seconds or less before the sheath is removed. Removing the sheath before the PTT drops below 50 seconds can cause bleeding at the insertion site. The other PTT results are incorrect for determining when to remove the sheath.

Shortly after being admitted to the coronary care unit with an acute myocardial infarction (MI), a client reports midsternal chest pain radiating down his left arm. The nurse notes that the client is restless and slightly diaphoretic, and measures a temperature of 99.6° F (37.6° C); a heart rate of 102 beats/minute; regular, slightly labored respirations at 26 breaths/minute; and a blood pressure of 150/90 mm Hg. Which nursing diagnosis takes highest priority? a) Decreased cardiac output b) Risk for imbalanced body temperature c) Acute pain d) Anxiety

c) Acute pain The nursing diagnosis of Acute pain takes highest priority because it increases the client's pulse and blood pressure. During the acute phase of an MI, low-grade fever is an expected result of the body's response to myocardial tissue necrosis. This makes Risk for imbalanced body temperature an incorrect answer. The client's blood pressure and heart rate don't suggest a nursing diagnosis of Decreased cardiac output. Anxiety could be an appropriate nursing diagnosis, but addressing Acute pain (the priority concern) may alleviate the client's anxiety.

You are presenting a workshop at the senior citizens center about how the changes of aging predispose clients to vascular occlusive disorders. What would you name as the most common cause of peripheral arterial problems in the older adult? a) Raynaud's disease b) Coronary thrombosis c) Atherosclerosis d) Arteriosclerosis

c) Atherosclerosis Atherosclerosis is the most common cause of peripheral arterial problems in the older adult. The disease correlates with the aging process. The other choices may occur at any age.

A client with chest pain arrives in the emergency department and receives nitroglycerin, morphine (Duramorph), oxygen, and aspirin. The physician diagnoses acute coronary syndrome. When the client arrives on the unit, his vital signs are stable and he has no complaints of pain. The nurse reviews the physician's orders. In addition to the medications already given, which medication does the nurse expect the physician to order? a) Nitroprusside (Nipride) b) Furosemide (Lasix) c) Carvedilol (Coreg) d) Digoxin (Lanoxin)

c) Carvedilol (Coreg) A client with suspected myocardial infarction should receive aspirin, nitroglycerin, morphine, and a beta-adrenergic blocker such as carvedilol. Digoxin treats arrhythmias; there is no indication that the client is having arrhythmias. Furosemide is used to treat signs of heart failure, which isn't indicated at this point. Nitroprusside increases blood pressure. This client has stable vital signs and isn't hypotensive.

A client is recovering from coronary artery bypass graft (CABG) surgery. The nurse knows that for several weeks after this procedure, the client is at risk for certain conditions. During discharge preparation, the nurse should advise the client and his family to expect which common symptom that typically resolves spontaneously? a) Memory lapses b) Ankle edema c) Depression d) Dizziness

c) Depression For the first few weeks after CABG surgery, clients commonly experience depression, fatigue, incisional chest discomfort, dyspnea, and anorexia. Depression typically resolves without medical intervention. However, the nurse should advise family members that symptoms of depression don't always resolve on their own. They should make sure they recognize worsening symptoms of depression and know when to seek care. Ankle edema seldom follows CABG surgery and may indicate right-sided heart failure. Because this condition is a sign of cardiac dysfunction, the client should report ankle edema at once. Memory lapses reflect neurologic rather than cardiac dysfunction. Dizziness may result from decreased cardiac output, an abnormal condition following CABG surgery. This symptom warrants immediate physician notification.

A patient presents to the ED complaining of anxiety and chest pain after shoveling heavy snow that morning. The patient says that he has not taken nitroglycerin for months but did take three nitroglycerin tablets and although the pain is less, "They did not work all that well. " The patient shows the nurse the nitroglycerin bottle and the prescription was filled 12 months ago. The nurse anticipates which of the following physician orders? a) Serum electrolytes b) Ativan 1 mg orally c) Nitroglycerin SL d) Chest x-ray

c) Nitroglycerin SL Nitroglycerin is volatile and is inactivated by heat, moisture, air, light, and time. Nitroglycerin should be renewed every 6 months to ensure full potency. The client's tablets were expired and the nurse should anticipate administering nitroglycerin to assess if the chest pain subsides. The other choices may be ordered at a later time, but the priority is to relieve the patient's chest pain.

In the treatment of coronary artery disease (CAD), medications are often ordered to control blood pressure in the client. Which of the following is a primary purpose of using beta-adrenergic blockers in the nursing management of CAD? a) To decrease homocysteine levels b) To dilate coronary arteries c) To decrease workload of the heart d) To prevent angiotensin II conversion

c) To decrease workload of the heart Beta-adrenergic blockers are used in the treatment of CAD to decrease the myocardial oxygen by reducing heart rate and workload of the heart. Nitrates are used for vasodilation. Anti-lipid drugs (such as statins and Bvitamins) are used to decrease homocysteine levels. ACE inhibitors inhibit the conversion of angiotensin.

Creatine kinase-MB isoenzyme (CK-MB) can increase as a result of: a) skeletal muscle damage due to a recent fall. b) I.M. injection. c) myocardial necrosis. d) cerebral bleeding.

c) myocardial necrosis. An increase in CK-MB is related to myocardial necrosis. An increase in total CK might occur for several reasons, including brain injury, such as cerebral bleeding; skeletal muscle damage, which can result from I.M. injections or falls; muscular or neuromuscular disease; vigorous exercise; trauma; or surgery.

A nurse is caring for a client who had a three-vessel coronary bypass graft 4 days earlier. His cholesterol profile is as follows: total cholesterol 265 mg/dl, low-density lipoprotein (LDL) 139 mg/dl, and high-density lipoprotein (HDL) 32 mg/dl. The client asks the nurse how to lower his cholesterol. The nurse should tell the client that: a) his cholesterol is within the recommended guidelines and he doesn't need to lower it. b) he should begin a running program, working up to 2 miles per day. c) she'll ask the dietitian to talk with him about modifying his diet. d) he should take his statin medication and not worry about his cholesterol.

c) she'll ask the dietitian to talk with him about modifying his diet. A dietitian can help the client decrease the fat in his diet and make other beneficial dietary modifications. This client's total cholesterol isn't within the recommended guidelines; it should be less than 200 mg/dl. LDL should be less than 79 mg/dl, and HDL should be greater than 40 mg/dl. Although this client should take his statin medication, he should still be concerned about his cholesterol level and make other lifestyle changes, such as dietary changes, to help lower it. The client should increase his activity level, but he doesn't need to run 2 miles per day.

A client in the emergency department complains of squeezing substernal pain that radiates to the left shoulder and jaw. He also complains of nausea, diaphoresis, and shortness of breath. What should the nurse do? a) Complete the client's registration information, perform an electrocardiogram, gain I.V. access, and take vital signs. b) Alert the cardiac catheterization team, administer oxygen, attach a cardiac monitor, and notify the physician. c) Gain I.V. access, give sublingual nitroglycerin, and alert the cardiac catheterization team. d) Administer oxygen, attach a cardiac monitor, take vital signs, and administer sublingual nitroglycerin.

d) Administer oxygen, attach a cardiac monitor, take vital signs, and administer sublingual nitroglycerin. Cardiac chest pain is caused by myocardial ischemia. Therefore the nurse should administer supplemental oxygen to increase the myocardial oxygen supply, attach a cardiac monitor to help detect life-threatening arrhythmias, and take vital signs to ensure that the client isn't hypotensive before giving sublingual nitroglycerin for chest pain. Registration information may be delayed until the client is stabilized. Alerting the cardiac catheterization team or the physician before completing the initial assessment is premature.

Which condition most commonly results in coronary artery disease (CAD)? a) Renal failure b) Myocardial infarction c) Diabetes mellitus d) Atherosclerosis

d) Atherosclerosis Atherosclerosis (plaque formation), is the leading cause of CAD. Diabetes mellitus is a risk factor for CAD, but it isn't the most common cause. Myocardial infarction is a common result of CAD. Renal failure doesn't cause CAD, but the two conditions are related.

Which medication should a nurse have on hand when removing a sheath after cardiac catheterization? a) Heparin b) Adenosine (Adenocard) c) Protamine sulfate d) Atropine

d) Atropine Removing the sheath after cardiac catheterization may cause a vasovagal response, including bradycardia. The nurse should have atropine on hand to increase the client's heart rate if this occurs. Heparin thins the blood; clients should stop taking it before the sheath removal. Protamine sulfate is an antidote to heparin, but the nurse shouldn't administer it during sheath removal. Adenosine treats tachyarrhythmias.

The nurse is aware that a client who has been diagnosed with Prinzmetal's angina will present with which of the following symptoms? a) Radiating chest pain that lasts 15 minutes or less b) Chest pain of increased frequency, severity, and duration c) Prolonged chest pain that accompanies exercise d) Chest pain that occurs at rest and usually in the middle of the night

d) Chest pain that occurs at rest and usually in the middle of the night A client with Prinzmetal's angina will complain of chest pain that occurs at rest, usually between 12 and 8 AM, is sporadic over 3-6 months, and diminishes over time. Client with stable angina generally experience chest pain that lasts 15 minutes or less and may radiate. Clients with Cardiac Syndrome X experience prolonged chest pain that accompanies exercise and is not always relieved by medication. Client with unstable angina experience chest pain of increased frequency, severity, and duration that is poorly relieved by rest or oral nitrates.

Which of the following medications is given to patients diagnosed with angina and is allergic to aspirin? a) Diltiazem (Cardizem) b) Felodipine (Plendil) c) Amlodipine (Norvasc) d) Clopidogrel (Plavix)

d) Clopidogrel (Plavix) Plavix or Ticlid is given to patients who are allergic to aspirin or given in addition to aspirin to patients at high risk for MI. Norvasc, Cardizem, and Plendil are calcium channel blockers.

In providing nursing management to a client post-varicose vein surgery, the nurse would include which of the following teaching measures? Select all that apply. a) Cool compresses b) Take warm showers in the morning. c) Stand rather than sit. d) Elastic stockings e) Exercise f) Lower the extremities.

d) Elastic stockings e) Exercise Movement/exercise and use of elastic stocking aid in venous return. Cool compresses can cause vasoconstriction, which can diminish arterial blood flow. Elevation of legs can be helpful in aiding venous return. Standing or sitting for prolonged periods of time should be avoided. Showers in the morning can dilate blood vessels and contribute to venous congestion and edema.

A patient's elevated cholesterol levels are being managed with Lipitor, 40 mg daily. The nurse practitioner reviews the patient's blood work every 6 months before renewing the prescription. The nurse explains to the patient's daughter that this is necessary because of a major side effect of Lipitor that she is checking for. What is that side-effect? a) Hyperuricemia b) Hyperglycemia c) Gastrointestinal distress d) Increased liver enzymes

d) Increased liver enzymes Myopathy and increased liver enzymes are significant side effects of the statins, HMG-CoA reductase inhibitors that are used to affect lipoprotein metabolism.

After 2-hour onset of acute chest pain, the client is brought to the emergency department for evaluation. Elevation of which diagnostic findings would the nurse identify as suggestive of an acute myocardial infarction at this time? a) WBC (white blood cell) count b) Troponin I c) C-reactive protein d) Myoglobin

d) Myoglobin Myoglobin is a biomarker that rises in 2 to 3 hours after heart damage. Troponin is the gold standard for determining heart damage, but troponin I levels due not rise until 4 to 6 hours after MI. WBCs and C-reactive protein levels will rise but not until about day 3.

The nursing priority of care for a client exhibiting signs and symptoms of coronary artery disease should be to: a) educate the client about his symptoms. b) decrease anxiety. c) administer sublingual nitroglycerin. d) enhance myocardial oxygenation.

d) enhance myocardial oxygenation. Enhancing myocardial oxygenation is always the first priority when a client exhibits signs or symptoms of cardiac compromise. Without adequate oxygen, the myocardium suffers damage. A nurse administers sublingual nitroglycerin to treat acute angina pectoris, but its administration isn't the first priority. Although educating the client and decreasing anxiety are import in care delivery, neither is a priority when a client is compromised.
