Cardiovascular Questions Part 2

24. The client has just returned from a cardiac catheterization. Which assessment data would warrant immediate intervention from the nurse? 1. The client's BP is 110/70 and pulse is 90. 2. The client's groin dressing is dry and intact. 3. The client refuses to keep the leg straight. 4. The client denies any numbness and tingling. 1. These vital signs are within normal limits and would not require any immediate intervention. 2. The groin dressing should be dry and intact. *3. If the client bends the leg, it could cause the insertion site to bleed. This is arterial blood and the client could bleed to death very quickly, so this requires immediate intervention. 4. The nurse must check the neurovascular assessment, and paresthesia would warrant immediate intervention, but no numbness and tingling is a good sign. 25. The male client is diagnosed with coronary artery disease (CAD) and is prescribed sublingual nitroglycerin. Which statement indicates the client needs more teaching? 1. "I should keep the tablets in the dark-colored bottle they came in." 2. "If the tablets do not burn under my tongue, they are not effective." 3. "I should keep the bottle with me in my pocket at all times." 4. "If my chest pain is not gone with one tablet, I will go to the ER." 1. If the tablets are not kept in a dark bottle, they will lose their potency. 2. The tablets should burn or sting when put under the tongue. 3. The client should keep the tablets with him in case of chest pain. *4. The client should take one tablet every five (5) minutes and, if no relief occurs after the third tablet, have someone drive him to the emergency department or call 911. 26. The client with coronary artery disease asks the nurse, "Why do I get chest pain?" Which statement would be the most appropriate response by the nurse? 1. "Chest pain is caused by decreased oxygen to the heart muscle." 2. "There is ischemia to the myocardium as a result of hypoxemia." 3. "The heart muscle is unable to pump effectively to perfuse the body." 4. "Chest pain occurs when the lungs cannot adequately oxygenate the blood." *1. This is a correct statement presented in layman's terms. When the coronary arteries cannot supply adequate oxygen to the heart muscle, there is chest pain. 2. This is the explanation in medical terms that should not be used when explaining medical conditions to a client. 3. This explains congestive heart failure but does not explain why chest pain occurs. 4. Respiratory compromise occurs when the lungs cannot oxygenate the blood, such as occurs with altered level of consciousness, cyanosis, and increased respiratory rate. 27. The client is scheduled for a right femoral cardiac catheterization. Which nursing intervention should the nurse implement after the procedure? 1. Perform passive range-of-motion exercises. 2. Assess the client's neurovascular status. 3. Keep the client in high Fowler's position. 4. Assess the gag reflex prior to feeding the client. 1. The client's right leg should be kept straight to prevent arterial bleeding from the femoral insertion site for the catheter used to perform the catheterization. *2. The nurse must make sure that blood is circulating to the right leg, so the client should be assessed for pulses, paresthesia, paralysis, coldness, and pallor. 3. The head of the bed should be elevated no more than 10 degrees. The client should be kept on bedrest, flat with the affected extremity straight, to help decrease the chance of femoral artery bleeding. 4. The gag reflex is assessed if a scope is inserted down the trachea (bronchoscopy) or esophagus (endoscopy) because the throat is numbed when inserting the scope. A catheter is inserted in the femoral or brachial artery when performing a cardiac catheterization. 28. The nurse is preparing to administer a beta blocker to the client diagnosed with coronary artery disease. Which assessment data would cause the nurse to question administering the medication? 1. The client has a BP of 110/70. 2. The client has an apical pulse of 56. 3. The client is complaining of a headache. 4. The client's potassium level is 4.5 mEq/L. 1. This blood pressure is normal and the nurse would administer the medication. *2. A beta blocker decreases sympathetic stimulation to the heart, thereby decreasing the heart rate. An apical rate less than 60 indicates a lowerthannormal heart rate and should make the nurse question administering this medication because it will further decrease the heart rate. 3. A headache will not affect administering the medication to the client. 4. The potassium level is within normal limits, but it is usually not monitored prior to administering a beta blocker. 29. Which intervention should the nurse implement when administering a loop diuretic to a client diagnosed with coronary artery disease? 1. Assess the client's radial pulse. 2. Assess the client's serum potassium level. 3. Assess the client's glucometer reading. 4. Assess the client's pulse oximeter reading. 1. The nurse should always assess the apical (not radial) pulse, but the pulse is not affected by a loop diuretic. *2. Loop diuretics cause potassium to be lost in the urine output. Therefore, the nurse should assess the client's potassium level, and if the client is hypokalemic, the nurse should question administering this medication. 3. The glucometer provides a glucose level, which is not affected by a loop diuretic. 4. The pulse oximeter reading evaluates peripheral oxygenation and is not affected by a loop diuretic. 30. Which client teaching should the nurse implement for the client diagnosed with coronary artery disease? Select all that apply. 1. Encourage a low-fat, lowcholesterol diet. 2. Instruct client to walk 30 minutes a day. 3. Decrease the salt intake to two (2) g a day. 4. Refer to counselor for stress reduction techniques. 5. Teach the client to increase fiber in the diet. *1. A low-fat, lowcholesterol diet will help decrease the buildup of atherosclerosis in the arteries. *2. Walking will help increase collateral circulation. 3. Salt should be restricted in the diet of a client with hypertension, not coronary artery disease. *4. Stress reduction is encouraged for clients with CAD because this helps prevent excess stress on the heart muscle. *5. Increasing fiber in the diet will help remove cholesterol via the gastrointestinal system. 31. The elderly client has coronary artery disease. Which question should the nurse ask the client during the client teaching? 1. "Do you have a daily bowel movement?" 2. "Do you get yearly chest x-rays?" 3. "Are you sexually active?" 4. "Have you had any weight change?" 1. Bowel movements are important, but they are not pertinent to coronary artery disease. 2. Chest x-rays are usually done for respiratory problems, not for coronary artery disease. *3. Sexual activity is a risk factor for angina resulting from coronary artery disease. The client's being elderly should not affect the nurse's assessment of the client's concerns about sexual activity. 4. Weight change is not significant in a client with coronary artery disease. 32. The nurse is discussing the importance of exercise with the client diagnosed with coronary artery disease. Which intervention should the nurse implement? 1. Perform isometric exercises daily. 2. Walk for 15 minutes three (3) times a week. 3. Do not walk outside if it is less than 40˚F. 4. Wear open-toed shoes when ambulating. 1. Isometric exercises are weight lifting-type exercises. A client with CAD should perform isotonic exercises, which increase muscle tone, not isometric exercises. 2. The client should walk at least 30 minutes a day to increase collateral circulation. *3. When it is cold outside, vasoconstriction occurs, and this will decrease oxygen to the heart muscle. Therefore, the client should not exercise when it is cold outside. 4. The client should wear good supportive tennis shoes when ambulating, not sandals or other open-toed shoes. 33. The nurse is discussing angina with a client who is diagnosed with coronary artery disease. Which action should the client take first when experiencing angina? 1. Put a nitroglycerin tablet under the tongue. 2. Stop the activity immediately and rest. 3. Document when and what activity caused angina. 4. Notify the health-care provider immediately. 1. The client should take the coronary vasodilator nitroglycerin sublingually, but it is not the first intervention. *2. Stopping the activity decreases the heart's need for oxygen and may help decrease the angina (chest pain). 3. The client should keep a diary of when angina occurs, what activity causes it, and how many nitroglycerin tablets are taken before chest pain is relieved. 4. If the chest pain (angina) is not relieved with three (3) nitroglycerin tablets, the client should call 911 or have someone take him to the emergency department. Notifying the HCP may take too long. 34. The client with coronary artery disease is prescribed a Holter monitor. Which intervention should the nurse implement? 1. Instruct client to keep a diary of activity, especially when having chest pain. 2. Discuss the need to remove the Holter monitor during a.m. care and showering. 3. Explain that all medications should be withheld while wearing a Holter monitor. 4. Teach the client the importance of decreasing activity while wearing the monitor. *1. The Holter monitor is a 24-hour electrocardiogram, and the client must keep an accurate record of activity so that the health-care provider can compare the ECG recordings with different levels of activity. 2. The Holter monitor should not be removed for any reason. 3. All medications should be taken as prescribed. 4. The client should perform all activity as usual while wearing the Holter monitor so the HCP can get an accurate account of heart function during a 24hour period. 35. Which statement by the client diagnosed with coronary artery disease indicates that the client understands the discharge teaching concerning diet? 1. "I will not eat more than six (6) eggs a week." 2. "I should bake or grill any meats I eat." 3. "I will drink eight (8) ounces of whole milk a day." 4. "I should not eat any type of pork products." 1. According to the American Heart Association, the client should not eat more than three (3) eggs a week, especially the egg yolk. *2. The American Heart Association recommends a low-fat, low-cholesterol diet for a client with coronary artery disease. The client should avoid any fried foods, especially meats, and bake, broil, or grill any meat. 3. The client should drink low-fat milk, not whole milk. 4. Pork products (bacon, sausage, ham) are high in sodium, which is prohibited in a low-salt diet, not a lowcholesterol, lowfat diet. 36. The charge nurse is making assignments for clients on a cardiac unit. Which client should the charge nurse assign to a new graduate nurse? 1. The 44-year-old client diagnosed with a myocardial infarction. 2. The 65-year-old client admitted with unstable angina. 3. The 75-year-old client scheduled for a cardiac catheterization. 4. The 50-year-old client complaining of chest pain. 1. This client is at high risk for complications related to necrotic myocardial tissue and will need extensive teaching, so this client should not be assigned to a new graduate. 2. Unstable angina means this client is at risk for life-threatening complications and should not be assigned to a new graduate. *3. A new graduate should be able to complete a preprocedure checklist and get this client to the catheterization laboratory. 4. Chest pain means this client could be having a myocardial infarction and should not be assigned to a new graduate. 37. A client is being seen in the clinic to R/O mitral valve stenosis. Which assessment data would be most significant? 1. The client complains of shortness of breath when walking. 2. The client has jugular vein distention and 3+ pedal edema. 3. The client complains of chest pain after eating a large meal. 4. The client's liver is enlarged and the abdomen is edematous. *1. Dyspnea on exertion (DOE) is typically the earliest manifestation of mitral valve stenosis. 2. Jugular vein distention (JVD) and 3+ pedal edema are signs/symptoms of right-sided heart failure and indicate worsening of the mitral valve stenosis. These signs would not be expected in a client with early manifestations of mitral valve stenosis. 3. Chest pain rarely occurs with mitral valve stenosis. 4. An enlarged liver and edematous abdomen are late signs of right-sided heart failure that can occur with long-term untreated mitral valve stenosis. 38. Which assessment data would the nurse expect to auscultate in the client diagnosed with mitral valve insufficiency? 1. A loud S1, S2 split, and a mitral opening snap. 2. A holosystolic murmur heard best at the cardiac apex. 3. A midsystolic ejection click or murmur heard at the base. 4. A high-pitched sound heard at the third left intercostal space. 1. This would be expected with mitral valve stenosis. *2. The murmur associated with mitral valve insufficiency is loud, highpitched, rumbling, and holosystolic (occurring throughout systole) and is heard best at the cardiac apex. 3. This would be expected with mitral valve prolapse. 4. This would be expected with aortic regurgitation. 39. The client has just received a mechanical valve replacement. Which behavior by the client indicates the client needs more teaching? 1. The client takes prophylactic antibiotics. 2. The client uses a soft-bristle toothbrush. 3. The client takes an enteric-coated aspirin daily. 4. The client alternates rest with activity. 1. Prophylactic antibiotics before invasive procedures prevent infectious endocarditis. 2. The client is undergoing anticoagulant therapy and should use a soft-bristle toothbrush to help prevent gum trauma and bleeding. *3. Aspirin and nonsteroidal antiinflammatory drugs (NSAIDs) interfere with clotting and may potentiate the effects of the anticoagulant therapy, which the client with a mechanical valve will be prescribed. Therefore, the client should not take aspirin daily. 4. The client should alternate rest with activity to prevent fatigue to help decrease the workload of the heart. 40. The nurse is teaching a class on valve replacements. Which statement identifies a disadvantage of having a biological tissue valve replacement? 1. The client must take lifetime anticoagulant therapy. 2. The client's infections are easier to treat. 3. There is a low incidence of thromboembolism. 4. The valve has to be replaced frequently. 1. An advantage of having a biological valve replacement is that no anticoagulant therapy is needed. Anticoagulant therapy is needed with a mechanical valve replacement. 2. This is an advantage of having a biological valve replacement; infections are harder to treat in clients with mechanical valve replacement. 3. This is an advantage of having a biological valve replacement; there is a high incidence of thromboembolism in clients with mechanical valve replacement. *4. Biological valves deteriorate and need to be replaced frequently; this is a disadvantage of them. Mechanical valves do not deteriorate and do not have to be replaced often. 41. The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client with a mechanical valve replacement. The client's international normalized ratio (INR) is 2.7. Which action should the nurse implement? 1. Administer the medication as ordered. 2. Prepare to administer vitamin K (AquaMephyton). 3. Hold the medication and notify the HCP. 4. Assess the client for abnormal bleeding. *1. The therapeutic range for most clients' INR is 2 to 3, but for a client with a mechanical valve replacement it is 2 to 3.5. The medication should be given as ordered and not withheld. 2. Vitamin K is the antidote for an overdose of warfarin, but 2.7 is within therapeutic range. 3. This laboratory result is within the therapeutic range, INR 2 to 3, and the medication does not need to be withheld. 4. There is no need for the nurse to assess for bleeding because 2.7 is within therapeutic range. 42. Which signs/symptoms should the nurse assess in any client who has a long-term valvular heart disease? Select all that apply. 1. Paroxysmal nocturnal dyspnea. 2. Orthopnea. 3. Cough. 4. Pericardial friction rub. 5. Pulsus paradoxus. *1. Paroxysmal nocturnal dyspnea is a sudden attack of respiratory distress, usually occurring at night because of the reclining position, and occurs in valvular disorders. *2. This is an abnormal condition in which a client must sit or stand to breathe comfortably and occurs in valvular disorders. *3. Coughing occurs when the client with long-term valvular disease has difficulty breathing when walking or performing any type of activity. 4. Pericardial friction rub is a sound auscultated in clients with pericarditis, not valvular heart disease. 5. Pulsus paradoxus is a marked decrease in amplitude during inspiration. It is a sign of cardiac tamponade, not valvular heart disease. 43. The client is being evaluated for valvular heart disease. Which information would be most significant? 1. The client has a history of coronary artery disease. 2. There is a family history of valvular heart disease. 3. The client has a history of smoking for 10 years. 4. The client has a history of rheumatic heart disease. 1. An acute myocardial infarction can damage heart valves, causing tearing, ischemia, or damage to heart muscles that affects valve leaflet function, but coronary heart disease does not cause valvular heart disease. 2. Valvular heart disease does not show a genetic etiology. 3. Smoking can cause coronary artery disease, but it does not cause valvular heart disease. *4. Rheumatic heart disease is the most common cause of valvular heart disease. 44. The client who has just had a percutaneous balloon valvuloplasty is in the recovery room. Which intervention should the recovery room nurse implement? 1. Assess the client's chest tube output. 2. Monitor the client's chest dressing. 3. Evaluate the client's endotracheal (ET) lip line. 4. Keep the client's affected leg straight. 1. Percutaneous balloon valvuloplasty is not an open-heart surgery; therefore, the chest will not be open and the client will not have a chest tube. 2. This is not an open-heart surgery; therefore, the client will not have a chest dressing. 3. The endotracheal (ET) tube is inserted if the client is on a ventilator, and this surgery does not require putting the client on a ventilator. *4. In this invasive procedure, performed in a cardiac catheterization laboratory, the client has a catheter inserted into the femoral artery. Therefore, the client must keep the leg straight to prevent hemorrhaging at the insertion site. 45. The client with a mechanical valve replacement asks the nurse, "Why do I have to take antibiotics before getting my teeth cleaned?" Which response by the nurse is most appropriate? 1. "You are at risk of developing an infection in your heart." 2. "Your teeth will not bleed as much if you have antibiotics." 3. "This procedure may cause your valve to malfunction." 4. "Antibiotics will prevent vegetative growth on your valves." *1. The client is at risk for developing endocarditis and should take prophylactic antibiotics before any invasive procedure. 2. Antibiotics have nothing to do with how much the teeth bleed during a cleaning. 3. Teeth cleaning will not cause the valve to malfunction. 4. Vegetation develops on valves secondary to bacteria that cause endocarditis, but the client may not understand "vegetative growth on your valves"; therefore, this is not the most appropriate answer.
