Exam (elaborations) NURS 101 Nclex-Exam Practice p164 1. Once a nurse assesses a client’s condition and identifies appropriate nursing diagnoses, a: 1. Plan is developed for nursing care. 2. Physical assessment begins 3. List of priorities is determined. 4. Review of the assessment is conducted with other team members. 2. Planning is a category of nursing behaviors in which: 1. The nurse determines the health care needed for the client. 2. The Physician determines the plan of care for the client. 3. Client-centered goals and expected outcomes are established. 4. The client determines the care needed. 3. Priorities are established to help the nurse anticipate and sequence nursing interventions when a client has multiple problems or alterations. Priorities are determined by the client’s: 1. Physician 2. Non Emergent, non-life threatening needs 3. Future well-being. 4. Urgency of problems 4. A client centered goal is a specific and measurable behavior or response that reflects a client’s: 1. Desire for specific health care interventions 2. Highest possible level of wellness and independence in function. 3. Physician’s goal for the specific client. 4. Response when compared to another client with a like problem. 5. For clients to participate in goal setting, they should be: 1. Alert and have some degree of independence. 2. Ambulatory and mobile. 3. Able to speak and write. 4. Able to read and write. 6. The nurse writes an expected outcome statement in measurable terms. An example is: 1. Client will have less pain. 2. Client will be pain free. 3. Client will report pain acuity less than 4 on a scale of 0-10. 4. Client will take pain medication every 4 hours around the clock. 1 NURS 101 Nclex-Exam Practice p164 7. As goals, outcomes, and interventions are developed, the nurse must: 1. Be in charge of all care and planning for the client. 2. Be aware of and committed to accepted standards of practice from nursing and other disciples. 3. Not change the plan of care for the client. 4. Be in control of all interventions for the client. 8. When establishing realistic goals, the nurse: 1. Bases the goals on the nurse’s personal knowledge. 2. Knows the resources of the health care facility, family, and the client. 3. Must have a client who is physically and emotionally stable. 4. Must have the client’s cooperation. 9. To initiate an intervention the nurse must be competent in three areas, which include: 1. Knowledge, function, and specific skills 2. Experience, advanced education, and skills. 3. Skills, finances, and leadership. 4. Leadership, autonomy, and skills. 10. Collaborative interventions are therapies that require: 1. Physician and nurse interventions. 2. Nurse and client interventions. 3. Client and Physician intervention. 4. Multiple health care professionals. 11. Well formulated, client-centered goals should: 1. Meet immediate client needs. 2. Include preventative health care. 3. Include rehabilitation needs. 4. All of the above. 12. The following statement appears on the nursing care plan for an immunosuppressed client: The client will remain free from infection throughout hospitalization. This statement is an example of a (an): 1. Nursing diagnosis 2. Short-term goal 3. Long-term goal 4. Expected outcome 13.

After determining a nursing diagnosis of acute pain, the nurse develops the following appropriate client-centered goal: 1. Encourage client to implement guided imagery when pain begins. 2. Determine effect of pain intensity on client function. 3. Administer analgesic 30 minutes before physical therapy treatment. 4. Pain intensity reported as a 3 or less during hospital stay. 17. When developing a nursing care plan for a client with a fractured right tibia, the nurse includes in the plan of care independent nursing interventions, including: 1. Apply a cold pack to the tibia. 2. Elevate the leg 5 inches above the heart. 3. Perform range of motion to right leg every 4 hours. 4. Administer aspirin 325 mg every 4 hours as needed. 18.

Calling in the wound care nurse as a consultant is appropriate because he or she is a specialist in the area of wound management. Professional and competent nurses recognize limitations and seek appropriate consultation. (a. This might be appropriate after deciding on a plan of action with the wound care nurse specialist. The nurse may need to obtain orders for special wound care products. c. Unless the nurse is knowledgeable in wound management, this could delay wound healing. Also, the current wound management plan could have been ordered by the physician. d. Another nurse most likely will not be knowledgeable about wounds, and the primary nurse would know the history of the wound management plan.) 20. A. This gives the consulting nurse facts that will influence a new plan. (b, c, and d. These are all subjective and emotional issues/conclusions about the current treatment plan and may cause a bias in the decision of a new treatment plan by the nurse consultant.) 21. D. Because the primary nurse requested the consultation, it is important that they communicate and discuss recommendations. The primary nurse can then accept or reject the CNS recommendations. (a. Some of the recommendations may not be appropriate for this client. The primary nurse would know this information. A consultation requires review of the recommendations, but not immediate implementation. b. This would be appropriate after first talking with the CNS about 4 recommended changes in the plan of care and the rationale. Then the primary nurse should call the physician. c. The client and family do not have the knowledge to determine whether new strategies are appropriate or not. Better to wait until the new plan of care is agreed upon by the primary nurse and physician before talking with the client and/or family.) 22. C, D, A, B. 23. B. 24. B.

Topics  Coronary Artery Disease  Hypertension Guidelines  Read each question carefully and choose the best answer.  You are given one minute per question. Spend your time wisely!  Answers and rationales are given below. Be sure to read them.  If you need more clarifications, please direct them to the comments section. Questions 1. A client is scheduled for a cardiac catheterization using a radiopaque dye. Which of the following assessments is most critical before the procedure? 1. Intake and output 2. Baseline peripheral pulse rates 3. Height and weight 4. Allergy to iodine or shellfish 2. A client with no history of cardiovascular disease comes into the ambulatory clinic with flu-like symptoms. The client suddenly complains of chest pain. Which of the following questions would best help a nurse to discriminate pain caused by a non-cardiac problem? 1. “Have you ever had this pain before?” 2. “Can you describe the pain to me?” 3. “Does the pain get worse when you breathe in?” 4. “Can you rate the pain on a scale of 1-10, with 10 being the worst?” 3. A client with myocardial infarction has been transferred from a coronary care unit to a general medical unit with cardiac monitoring via telemetry. A nurse plans to allow for which of the following client activities? 1. Strict bed rest for 24 hours after transfer 2. Bathroom privileges and self-care activities 3. Unsupervised hallway ambulation with distances under 200 feet 4. Ad lib activities because the client is monitored. 5 4. A nurse notes 2+ bilateral edema in the lower extremities of a client with myocardial infarction who was admitted 2 days ago. The nurse would plan to do which of the following next? 1. Review the intake and output records for the last 2 days 2. Change the time of diuretic administration from morning to evening 3. Request a sodium restriction of 1 g/day from the physician. 4. Order daily weights starting the following morning. 5. A client is wearing a continuous cardiac monitor, which begins to sound its alarm. A nurse sees no electrocardiogram complexes on the screen. The first action of the nurse is to: 1. Check the client status and lead placement 2. Press the recorder button on the electrocardiogram console. 3. Call the physician 4. Call a code blue 6. A nurse is assessing the blood pressure of a client diagnosed with primary hypertension. The nurse ensures accurate measurement by avoiding which of the following? 1. Seating the client with arm bared, supported, and at heart level. 2. Measuring the blood pressure after the client has been seated quietly for 5 minutes. 3. Using a cuff with a rubber bladder that encircles at least 80% of the limb. 4. Taking a blood pressure within 15 minutes after nicotine or caffeine ingestion. 7. IV heparin therapy is ordered for a client. While implementing this order, a nurse ensures that which of the following medications is available on the nursing unit? 1. Vitamin K 2. Aminocaproic acid 3. Potassium chloride 4. Protamine sulfate 8. A client is at risk for pulmonary embolism and is on anticoagulant therapy with warfarin (Coumadin). The client’s prothrombin time is 20 seconds, with a control of 11 seconds. The nurse assesses that this result is: 1. The same as the client’s own baseline level 2. Lower than the needed therapeutic level 3. Within the therapeutic range 4. Higher than the therapeutic range 9. A client who has been receiving heparin therapy also is started on warfarin. The client asks a nurse why both medications are being administered. In formulating a response, the nurse incorporates the understanding that warfarin: 1. Stimulates the breakdown of specific clotting factors by the liver, and it takes 2-3 days for this to exert an anticoagulant effect. 2. Inhibits synthesis of specific clotting factors in the liver, and it takes 3-4 days for this medication to exert an anticoagulant effect. 3. Stimulates production of the body’s own thrombolytic substances, but it takes 2-4 days for this to begin. 4. Has the same mechanism of action as Heparin, and the crossover time is needed for the serum level of warfarin to be therapeutic. 10. A 60-year-old male client comes into the emergency department with complaints of crushing chest pain that radiates to his shoulder and left arm. The admitting diagnosis is acute myocardial infarction. Immediate admission orders include oxygen by NC at 6 4L/minute, blood work, chest x-ray, an ECG, and 2 mg of morphine given intravenously. The nurse should first: 1. Administer the morphine 2. Obtain a 12-lead ECG 3. Obtain the lab work 4. Order the chest x-ray 11. When administered a thrombolytic drug to the client experiencing an MI, the nurse explains to him that the purpose of this drug is to: 1. Help keep him well hydrated 2. Dissolve clots he may have 3. Prevent kidney failure 4. Treat potential cardiac arrhythmias. 12. When interpreting an ECG, the nurse would keep in mind which of the following about the P wave? Select all that apply. 1. Reflects electrical impulse beginning at the SA node 2. Indicated electrical impulse beginning at the AV node 3. Reflects atrial muscle depolarization 4. Identifies ventricular muscle depolarization 5. Has duration of normally 0.11 seconds or less. 13. A client has driven himself to the ER. He is 50 years old, has a history of hypertension, and informs the nurse that his father died of a heart attack at 60 years of age. The client is presently complaining of indigestion. The nurse connects him to an ECG monitor and begins administering oxygen at 2 L/minute per NC. The nurse’s next action would be to: 1. Call for the doctor 2. Start an intravenous line 3. Obtain a portable chest radiograph 4. Draw blood for laboratory studies 14. The nurse receives emergency laboratory results for a client with chest pain and immediately informs the physician. An increased myoglobin level suggests which of the following? 1. Cancer 2. Hypertension 3. Liver disease 4. Myocardial infarction 15. When teaching a client about propranolol hydrochloride, the nurse should base the information on the knowledge that propranolol hydrochloride: 1. Blocks beta-adrenergic stimulation and thus causes decreased heart rate, myocardial contractility, and conduction. 2. Increases norepinephrine secretion and thus decreases blood pressure and heart rate. 3. Is a potent arterial and venous vasodilator that reduces peripheral vascular resistance and lowers blood pressure. 4. Is an angiotensin-converting enzyme inhibitor that reduces blood pressure by blocking the conversion of angiotensin I to angiotensin II. 16. The most important long-term goal for a client with hypertension would be to: 1. Learn how to avoid stress 2. Explore a job change or early retirement 7 3. Make a commitment to long-term therapy 4. Control high blood pressure 17. Hypertension is known as the silent killer. This phrase is associated with the fact that hypertension often goes undetected until symptoms of other system failures occur. This may occur in the form of: 1. Cerebrovascular accident 2. Liver disease 3. Myocardial infarction 4. Pulmonary disease 18. During the previous few months, a 56-year-old woman felt brief twinges of chest pain while working in her garden and has had frequent episodes of indigestion. She comes to the hospital after experiencing severe anterior chest pain while raking leaves. Her evaluation confirms a diagnosis of stable angina pectoris. After stabilization and treatment, the client is discharged from the hospital. At her follow-up appointment, she is discouraged because she is experiencing pain with increasing frequency. She states that she is visiting an invalid friend twice a week and now cannot walk up the second flight of steps to the friend’s apartment without pain. Which of the following measures that the nurse could suggest would most likely help the client deal with this problem? 1. Visit her friend earlier in the day. 2. Rest for at least an hour before climbing the stairs. 3. Take a nitroglycerin tablet before climbing the stairs. 4. Lie down once she reaches the friend’s apartment. 19. Which of the following symptoms should the nurse teach the client with unstable angina to report immediately to her physician? 1. A change in the pattern of her pain 2. Pain during sex 3. Pain during an argument with her husband 4. Pain during or after an activity such as lawn mowing 20. The physician refers the client with unstable angina for a cardiac catheterization. The nurse explains to the client that this procedure is being used in this specific case to: 1. Open and dilate the blocked coronary arteries 2. Assess the extent of arterial blockage 3. Bypass obstructed vessels 4. Assess the functional adequacy of the valves and heart muscle. 21. As an initial step in treating a client with angina, the physician prescribes nitroglycerin tablets, 0.3mg given sublingually. This drug’s principal effects are produced by: 1. Antispasmodic effect on the pericardium 2. Causing an increased myocardial oxygen demand 3. Vasodilation of peripheral vasculature 4. Improved conductivity in the myocardium 22. The nurse teaches the client with angina about the common expected side effects of nitroglycerin, including: 1. Headache 2. High blood pressure 3. Shortness of breath 4. Stomach cramps 8 23. Sublingual nitroglycerin tablets begin to work within 1 to 2 minutes. How should the nurse instruct the client to use the drug when chest pain occurs? 1. Take one tablet every 2 to 5 minutes until the pain stops. 2. Take one tablet and rest for 10 minutes. Call the physician if pain persists after 10 minutes. 3. Take one tablet, then an additional tablet every 5 minutes for a total of 3 tablets. Call the physician if pain persists after three tablets. 4. Take one tablet. If pain persists after 5 minutes, take two tablets. If pain still persists 5 minutes later, call the physician. 24. Which of the following arteries primarily feeds the anterior wall of the heart? 1. Circumflex artery 2. Internal mammary artery 3. Left anterior descending artery 4. Right coronary artery 25. When do coronary arteries primarily receive blood flow? 1. During inspiration 2.

Which of the following terms describes the force against which the ventricle must expel blood? 1. Afterload 2. Cardiac output 3. Overload 4. Preload 35. Which of the following terms is used to describe the amount of stretch on the myocardium at the end of diastole? 1. Afterload 2. Cardiac index 3. Cardiac output 4. Preload 36. A 57-year-old client with a history of asthma is prescribed propranolol (Inderal) to control hypertension. Before administered propranolol, which of the following actions should the nurse take first? 1. Monitor the apical pulse rate 2. Instruct the client to take medication with food 3. Question the physician about the order 4. Caution the client to rise slowly when standing. 37. One hour after administering IV furosemide (Lasix) to a client with heart failure, a short burst of ventricular tachycardia appears on the cardiac monitor. Which of the following electrolyte imbalances should the nurse suspect? 1. Hypocalcemia 2. Hypermagnesemia 3. Hypokalemia 4. Hypernatremia 38. A client is receiving spironolactone to treat hypertension. Which of the following instructions should the nurse provide? 1. “Eat foods high in potassium.” 2. “Take daily potassium supplements.” 10 3. “Discontinue sodium restrictions.” 4. “Avoid salt substitutes.” 39. When assessing an ECG, the nurse knows that the P-R interval represents the time it takes for the: 1. Impulse to begin atrial contraction 2. Impulse to transverse the atria to the AV node 3. SA node to discharge the impulse to begin atrial depolarization 4. Impulse to travel to the ventricles 40. Following a treadmill test and cardiac catheterization, the client is found to have coronary artery disease, which is inoperative. He is referred to the cardiac rehabilitation unit. During his first visit to the unit he says that he doesn’t understand why he needs to be there because there is nothing that can be done to make him better. The best nursing response is: 1. “Cardiac rehabilitation is not a cure but can help restore you to many of your former activities.” 2. “Here we teach you to gradually change your lifestyle to accommodate your heart disease.” 3. “You are probably right but we can gradually increase your activities so that you can live a more active life.” 4. “Do you feel that you will have to make some changes in your life now?” 41. To evaluate a client’s condition following cardiac catheterization, the nurse will palpate the pulse: 1. In all extremities 2. At the insertion site 3. Distal to the catheter insertion 4. Above the catheter insertion 42. A client’s physician orders nuclear cardiography and makes an appointment for a thallium scan. The purpose of injecting radioisotope into the bloodstream is to detect: 1. Normal vs. abnormal tissue 2. Damage in areas of the heart 3. Ventricular function 4. Myocardial scarring and perfusion 43. A client enters the ER complaining of severe chest pain. A myocardial infarction is suspected. A 12 lead ECG appears normal, but the doctor admits the client for further testing until cardiac enzyme studies are returned. All of the following will be included in the nursing care plan. Which activity has the highest priority? 1. Monitoring vital signs 2. Completing a physical assessment 3. Maintaining cardiac monitoring 4. Maintaining at least one IV access site 44. A client is experiencing tachycardia. The nurse’s understanding of the physiological basis for this symptom is explained by which of the following statements? 1. The demand for oxygen is decreased because of pleural involvement 2. The inflammatory process causes the body to demand more oxygen to meet its needs. 3. The heart has to pump faster to meet the demand for oxygen when there is lowered arterial oxygen tension. 4. Respirations are labored. 45. A client enters the ER complaining of chest pressure and severe epigastric distress. His VS are 158/90, 94, 24, and 99*F. The doctor orders cardiac enzymes. If the client were 11 diagnosed with an MI, the nurse would expect which cardiac enzyme to rise within the next 3 to 8 hours? 1. Creatine kinase (CK or CPK) 2. Lactic dehydrogenase (LDH) 3. LDH-1 4. LDH-2 46. A 45-year-old male client with leg ulcers and arterial insufficiency is admitted to the hospital. The nurse understands that leg ulcers of this nature are usually caused by: 1. Decreased arterial blood flow secondary to vasoconstriction 2. Decreased arterial blood flow leading to hyperemia 3. Atherosclerotic obstruction of the arteries 4. Trauma to the lower extremities 47. Which of the following instructions should be included in the discharge teaching for a patient discharged with a transdermal nitroglycerin patch? 1. “Apply the patch to a non hairy, nonfatty area of the upper torso or arms.” 2. “Apply the patch to the same site each day to maintain consistent drug absorption.” 3. “If you get a headache, remove the patch for 4 hours and then reapply.” 4. “If you get chest pain, apply a second patch right next to the first patch.” 48. In order to prevent the development of tolerance, the nurse instructs the patient to: 1. Apply the nitroglycerin patch every other day 2. Switch to sublingual nitroglycerin when the patient’s systolic blood pressure elevates to >140 mm Hg 3. Apply the nitroglycerin patch for 14 hours each and remove for 10 hours at night 4. Use the nitroglycerin patch for acute episodes of angina only 49. Direct-acting vasodilators have which of the following effects on the heart rate? 1. Heart rate decreases 2. Heart rate remains significantly unchanged 3. Heart rate increases 4. Heart rate becomes irregular 50. When teaching a patient why spironolactone (Aldactone) and furosemide (Lasix) are prescribed together, the nurse bases teaching on the knowledge that: 1. Moderate doses of two different types of diuretics are more effective than a large dose of one type 2. This combination promotes diuresis but decreases the risk of hypokalemia 3. This combination prevents dehydration and hypovolemia 4. Using two drugs increases osmolality of plasma and the glomerular filtration rate Answers and Rationale Gauge your performance by counter checking your answers to the answers below. Learn more about the question by reading the rationale. If you have any disputes or questions, please direct them to the comments section. 1. Answer: 4. This procedure requires an informed consent because it involves injection of a radiopaque dye into the blood vessel. The risk of allergic reaction and possible anaphylaxis is serious and must be assessed before the procedure. 2. Answer: 3. Chest pain is assessed by using the standard pain assessment parameters. Options 1, 2, and 4 may or may not help discriminate the origin of pain. Pain of pleuropulmonary origin usually worsens on inspiration. 12 3. Answer: 2. On transfer from the CCU, the client is allowed self-care activities and bathroom privileges. Supervised ambulation for brief distances are encouraged, with distances gradually increased (50, 100, 200 feet). 4. Answer: 1. Edema, the accumulation of excess fluid in the interstitial spaces, can be measured by intake greater than output and by a sudden increase in weight. Diuretics should be given in the morning whenever possible to avoid nocturia. Strict sodium restrictions are reserved for clients with severe symptoms. 5. Answer: 1. Sudden loss of electrocardiogram complexes indicates ventricular asystole or possible electrode displacement. Accurate assessment of the client and equipment is necessary to determine the cause and identify the appropriate intervention. 6. Answer: 4. BP should be taken with the client seated with the arm bared, positioned with support and at heart level. The client should sit with the legs on the floor, feet uncrossed, and not speak during the recording. The client should not have smoked tobacco or taken in caffeine in the 30 minutes preceding the measurement. The client should rest quietly for 5 minutes before the reading is taken. The cuff bladder should encircle at least 80% of the limb being measured. Gauges other than a mercury sphygmomanometer should be calibrated every 6 months to ensure accuracy. 7. Answer: 4. The antidote to heparin is protamine sulfate and should be readily available for use if excessive bleeding or hemorrhage should occur. Vitamin K is an antidote for warfarin. 8. . Detection of myoglobin is one diagnostic tool to determine whether myocardial damage has occurred. Myoglobin is generally Answer: 3. The therapeutic range for prothrombin time is 1.5 to 2 times the control for clients at risk for thrombus. Based on the client’s control value, the therapeutic range for this individual would be 16.5 to 22 seconds. Therefore the result is within therapeutic range. 9. Answer: 2. Warfarin works in the liver and inhibits synthesis of four vitamin K-dependent clotting factors (X, IX, VII, and II), but it takes 3 to 4 days before the therapeutic effect of warfarin is exhibited. 10. Answer: 1. Although obtaining the ECG, chest x-ray, and blood work are all important, the nurse’s priority action would be to relieve the crushing chest pain. 11. Answer: 2. Thrombolytic drugs are administered within the first 6 hours after onset of a MI to lyse clots and reduce the extent of myocardial damage. 12. Answer: 1, 3, 5. In a client who has had an ECG, the P wave represents the activation of the electrical impulse in the SA node, which is then transmitted to the AV node. In addition, the P wave represents atrial muscle depolarization, not ventricular depolarization. The normal duration of the P wave is 0.11 seconds or less in duration and 2.5 mm or more in height. 13. Answer: 2. Advanced cardiac life support recommends that at least one or two intravenous lines be inserted in one or both of the antecubital spaces. Calling the physician, obtaining a portable chest radiograph, and drawing blood are important but secondary to starting the intravenous line. 14. Answer: 4detected about one hour after a heart attack is experienced and peaks within 4 to 6 hours after infarction (Remember, less than 90 mg/L is normal). 15. Answer: 1. Propranolol hydrochloride is a beta-adrenergic blocking agent. Actions of propranolol hydrochloride include reducing heart rate, decreasing myocardial contractility, and slowing conduction. 16. Answer: 3. Compliance is the most critical element of hypertensive therapy. In most cases, hypertensive clients require lifelong treatment and their hypertension cannot be managed successfully without drug therapy. Stress management and weight management are important components of hypertension therapy, but the priority goal is related to compliance. 17. Answer: 1. Hypertension is referred to as the silent killer for adults, because until the adult has significant damage to other systems, the hypertension may go undetected. CVA’s can be related to 13 long-term hypertension. Liver or pulmonary disease is generally not associated with hypertension. Myocardial infarction is generally related to coronary artery disease. 18. Answer: 3. Nitroglycerin may be used prophylactically before stressful physical activities such as stair climbing to help the client remain pain free. Visiting her friend early in the day would have no impact on decreasing pain episodes. Resting before or after an activity is not as likely to help prevent an activity-related pain episode. 19. Answer: 1. The client should report a change in the pattern of chest pain. It may indicate increasing severity of CAD. 20. Answer: 2. Cardiac catheterization is done in clients with angina primarily to assess the extent and severity of the coronary artery blockage, A decision about medical management, angioplasty, or coronary artery bypass surgery will be based on the catheterization results. 21. Answer: 3. Nitroglycerin produces peripheral vasodilation, which reduces myocardial oxygen consumption and demand. Vasodilation in coronary arteries and collateral vessels may also increase blood flow to the ischemic areas of the heart. Nitroglycerin decreases myocardial oxygen demand. Nitroglycerin does not have an effect on pericardial spasticity or conductivity in the myocardium. 22. Answer: 1. Because of the widespread vasodilating effects, nitroglycerin often produces such side effects as headache, hypotension, and dizziness. The client should lie or shit down to avoid fainting. Nitro does not cause shortness of breath or stomach cramps. 23. Answer: 3. The correct protocol for nitroglycerin used involves immediate administration, with subsequent doses taken at 5-minute intervals as needed, for a total dose of 3 tablets. Sublingual nitroglycerin appears in the bloodstream within 2 to 3 minutes and is metabolized within about 10 minutes. 24. Answer: 3. The left anterior descending artery is the primary source of blood flow for the anterior wall of the heart. The circumflex artery supplies the lateral wall, the internal mammary supplies the mammary, and the right coronary artery supplies the inferior wall of the heart. 25. Answer: 2. Although the coronary arteries may receive a minute portion of blood during systole, most of the blood flow to coronary arteries is supplied during diastole. Breathing patterns are irrelevant to blood flow. 26. Answer: 3. The right coronary artery supplies the right ventricle, or the inferior portion of the heart. Therefore, prolonged occlusion could produce an infarction in that area. The right coronary artery doesn’t supply the anterior portion (left ventricle), lateral portion (some of the left ventricle and the left atrium), or the apical portion (left ventricle) of the heart. 27. Answer: 3. Abnormalities of the pulmonic valve are auscultated at the second left intercostal space along the left sternal border. Aortic valve abnormalities are heard at the second intercostal space, to the right of the sternum. Mitral valve abnormalities are heard at the fifth intercostal space in the midclavicular line. Tricupsid valve abnormalities are heard at the 3rd and 4th intercostal spaces along the sternal border. 28. Answer: 3. Troponin I levels rise rapidly and are detectable within 1 hour of myocardial injury. Troponin levels aren’t detectable in people without cardiac injury. 29. Answer: 4. The ECG is the quickest, most accurate, and most widely use
