253 - Cardiovascular NCLEX Questions

The nurse is performing an assessment on a client with a diagnosis of left-sided heart failure. Which assessment component would elicit specific information regarding the client's left-sided heart function? 1.Listening to lung sounds 2.Monitoring for organomegaly 3.Assessing for jugular vein distention 4.Assessing for peripheral and sacral edema

1. The client with heart failure may present with different symptoms, depending on whether the right or the left side of the heart is failing. Peripheral and sacral edema, jugular vein distention, and organomegaly all are manifestations of problems with right-sided heart function. Lung sounds constitute an accurate indicator of left-sided heart function.

The health care provider prescribes bedrest for a client who developed deep vein thrombosis (DVT) after surgery. What interventions should the nurse plan to include in the client's plan of care? Select all that apply. 1.Place in Fowler's position for eating. 2.Encourage coughing with deep breathing. 3.Encourage increased oral intake of water daily. 4.Place thigh-length elastic stockings on the client. 5.Place sequential compression boots on the client. 6.Encourage the intake of dark green, leafy vegetables.

2,3,4. The client with DVT may require bedrest to prevent embolization of the thrombus resulting from skeletal muscle action, anticoagulation to prevent thrombus extension and allow for thrombus autodigestion, fluids for hemodilution and to decrease blood viscosity, and elastic stockings to reduce peripheral edema and promote venous return. While the client is on bedrest, the nurse prevents complications of immobility by encouraging coughing and deep breathing. Venous return is important to maintain because it is a contributing factor in DVT, so the nurse maintains venous return from the lower extremities by avoiding hip flexion, which occurs with Fowler's position. The nurse avoids providing foods rich in vitamin K, such as dark green, leafy vegetables, because this vitamin can interfere with anticoagulation, thereby increasing the risk of additional thrombi and emboli. The nurse also would not include use of sequential compression boots for an existing thrombus. They are used only to prevent DVT, because they mimic skeletal muscle action and can disrupt an existing thrombus, leading to pulmonary embolism.

A nurse is caring for a client immediately after insertion of a permanent demand pacemaker via the right subclavian vein. Which activity will assist with preventing dislodgement of the pacing catheter? 1.Limiting both movement and abduction of the left arm 2.Limiting both movement and abduction of the right arm 3.Assisting the client to get out of bed and ambulate with a walker 4.Having the physical therapist do active range-of-motion exercises to the right arm

2. In the first several hours after insertion of a permanent or temporary pacemaker, the most common complication is pacing electrode dislodgement. The nurse helps prevent this complication by limiting the client's activities of the arm on the side of the insertion site. Therefore, options 1, 3, and 4 are incorrect.

A client with myocardial infarction has been transferred from a coronary care unit to a general medical unit with cardiac monitoring via telemetry. The nurse should plan to allow for which client activity? 1.Strict bed rest for 24 hours after transfer 2.Bathroom privileges and self-care activities 3.Ad lib activities because the client is monitored 4.Unsupervised hallway ambulation with distances under 200 feet

2. On transfer from the coronary care unit, the client is allowed self-care activities and bathroom privileges. Strict bedrest is unnecessary and can be harmful and promote emboli. Supervised ambulation in the hall for brief distances is encouraged, with distances gradually increased (50, 100, 200 feet).

A client with no history of cardiovascular disease comes to the ambulatory clinic with flu-like symptoms. The client suddenly complains of chest pain. Which question should best help a nurse discriminate pain caused by a noncardiac problem? 1."Can you describe the pain to me?" 2."Have you ever had this pain before?" 3."Does the pain get worse when you breathe in?" 4."Can you rate the pain on a scale of 1 to 10, with 10 being the worst?"

3. Chest pain is assessed by using the standard pain assessment parameters (e.g., characteristics, location, intensity, duration, precipitating and alleviating factors, and associated symptoms). The remaining options may or may not help discriminate the origin of pain. Pain of pleuropulmonary origin usually worsens on inspiration.

The nurse is giving discharge instructions to a client who has just undergone vein ligation and stripping. The nurse evaluates that the client understands activity and positioning limitations if the client states that which action is appropriate to do? 1.Walk for as long as possible each day. 2.Cross the legs at the ankle only, not at the knee. 3.Lie down with the legs elevated and avoid sitting. 4.Sit in a chair 3 times a day for 3 hours at a time.

3. The client who has had vein ligation and stripping should avoid standing or sitting for prolonged periods. The client should remain lying down unless performing a specific activity for the first few days after the procedure. Prolonged standing or sitting increases the risk of edema in the legs by decreasing blood return to the heart. The client should avoid crossing the legs at any level for the same reason.

A nurse is caring for a client with unstable ventricular tachycardia. The nurse should instruct the client to take which action, if prescribed, during an episode of ventricular tachycardia? 1.Lie down flat in bed. 2.Remove any metal jewelry. 3.Breathe deeply, regularly, and easily. 4.Inhale deeply and cough forcefully every 1 to 3 seconds.

4. Restorative coughing techniques are sometimes used in the client with unstable ventricular tachycardia. The nurse tells the client to use cough cardiopulmonary resuscitation (CPR), if prescribed, by inhaling deeply and coughing forcefully every 1 to 3 seconds. Cough CPR may terminate the dysrhythmia or sustain the cerebral and coronary circulation for a short time until other measures can be implemented. The other options will not assist in terminating the dysrhythmia.

The nurse is planning to teach a client with peripheral arterial disease about measures to limit disease progression. Which items should the nurse include on a list of suggestions for the client? Select all that apply. 1.Soak the feet in hot water daily. 2.Be careful not to injure the legs or feet. 3.Use a heating pad on the legs to aid vasodilation. 4.Walk each day to increase circulation to the legs. 5.Cut down on the amount of fats consumed in the diet.

2,4,5. Long-term management of peripheral arterial disease consists of measures that increase peripheral circulation (exercise), promote vasodilation (warmth), relieve pain, and maintain tissue integrity (foot care and nutrition). Soaking the feet in hot water and application of a heating pad to the extremity is contraindicated. The affected extremity may have decreased sensitivity and is at risk for burns. Also, the affected tissue does not obtain adequate circulation at rest. Direct application of heat raises oxygen and nutritional requirements of the tissue even further.

The nurse is developing a plan of care for a client with pulmonary edema. The nurse establishes a goal to have the client participate in activities that reduce cardiac workload. The nurse should identify which client action as contributing to this goal? 1.Using a bedside commode 2.Sleeping in the supine position 3.Elevating the legs when in bed 4.Using seasonings to improve the taste of food

1. Using a bedside commode decreases the work of getting to the bathroom or struggling to use the bedpan. The supine position increases respiratory effort and decreases oxygenation. Elevating the client's legs increases venous return to the heart, increasing cardiac workload. This increases cardiac workload. Seasonings may be high in sodium.

The nurse is providing instructions to a client with a diagnosis of hypertension regarding high-sodium items to be avoided. The nurse instructs the client to avoid consuming which item? 1.Bananas 2.Broccoli 3.Antacids 4.Cantaloupe

3. The sodium level can increase with the use of several types of products, including toothpaste and mouthwash; over-the-counter medications such as analgesics, antacids, laxatives, and sedatives; and softened water and mineral water. Clients are instructed to read labels for sodium content. Water that is bottled, distilled, deionized, or demineralized may be used for drinking and cooking. Fresh fruits and vegetables are low in sodium.

A client has been diagnosed with thromboangiitis obliterans (Buerger's disease). The nurse is identifying measures to help the client cope with lifestyle changes needed to control the disease process. The nurse plans to refer the client to which member of the health care team? 1.Dietitian 2.Medical social worker 3.Pain management clinic 4.Smoking-cessation program

4. Buerger's disease is a vascular occlusive disease that affects the medium and small arteries and veins. Smoking is highly detrimental to the client with Buerger's disease, so stopping smoking completely is recommended. Because smoking is a form of chemical dependency, referral to a smoking-cessation program may be helpful for many clients. For many clients with Buerger's disease, symptoms are relieved or alleviated once smoking stops. A dietitian, a medical social worker, and a pain management clinic are not specifically associated with the lifestyle changes required in this disorder although they may be needed if secondary problems arise.

The nurse is planning care for a client with deep vein thrombosis of the right leg. Which interventions would the nurse plan, based on the health care provider's prescriptions? Select all that apply. 1.Elevation of the right leg 2.Ambulation in the hall every 4 hours 3.Application of moist heat to the right leg 4.Administration of acetaminophen (Tylenol) 5.Monitoring for signs of pulmonary embolism

1,3,4,5. Standard management of the client with deep vein thrombosis includes possible bed rest for 5 to 7 days or as prescribed; limb elevation; relief of discomfort with warm, moist heat and analgesics as needed; anticoagulant therapy; and monitoring for signs of pulmonary embolism. Ambulation is contraindicated because it increases the likelihood of dislodgement of the tail of the thrombus, which could travel to the lungs as a pulmonary embolism.

A client who has had a myocardial infarction asks the nurse why she should not bear down or strain to ensure having a bowel movement. The nurse's response incorporates the information that bearing down or straining would trigger which physical response? 1.Vagus nerve stimulation, causing a decrease in heart rate and cardiac contractility 2.Vagus nerve stimulation, causing an increase in heart rate and cardiac contractility 3.Sympathetic nerve stimulation, causing an increase in heart rate and cardiac contractility 4.Sympathetic nerve stimulation, causing a decrease in heart rate and cardiac contractility

1. Bearing down as if straining to have a bowel movement can stimulate a vagal reflex. Stimulation of the vagus nerve causes a decrease in heart rate and cardiac contractility. Stimulation of the sympathetic nervous system has the opposite effect. These two branches of the autonomic nervous system oppose each other to maintain homeostasis.

A client has been experiencing difficulty with completion of daily activities because of underlying cardiovascular disease, as evidenced by exertional fatigue and increased blood pressure. Which observation by the nurse best indicates client progress in meeting goals for this problem? 1.Ambulates 10 feet farther each day 2.Verbalizes the benefits of increasing activity 3.Chooses a healthy diet that meets caloric needs 4.Sleeps without awakening throughout the night

1. Each of the options indicates a positive outcome on the part of the client. Both options 2 and the correct one relate to the client problem of difficulty with completion of daily activities. However, the question asks about progress. The correct option is more action-oriented and therefore is the better choice. Option 3 would most likely indicate progress if the client had a problem of inadequate nutritional intake. Option 4 would be a satisfactory outcome for a client experiencing difficulty sleeping.

A nurse is assessing a client's legs for the presence of edema. The nurse notes that the client has mild pitting with slight indentation and no perceptible swelling of the leg. How should the nurse define and document this finding? 1.1+ edema 2.2+ edema 3.3+ edema 4.4+ edema

1. Edema is accumulation of fluid in the intercellular spaces and is not normally present. To check for edema, the nurse would imprint his or her thumbs firmly against the ankle malleolus or the tibia. Normally, the skin surface stays smooth. If the pressure leaves a dent in the skin, pitting edema is present. Its presence is graded on the following 4-point scale: 1+, mild pitting, slight indentation, no perceptible swelling of the leg; 2+, moderate pitting, indentation subsides rapidly; 3+, deep pitting, indentation remains for a short time, leg looks swollen; 4+, very deep pitting, indentation lasts a long time, and leg is very swollen.

The nurse is performing an admission assessment on a client with a diagnosis of angina pectoris who takes nitroglycerin for chest pain at home. During the assessment the client complains of chest pain. The nurse should immediately ask the client which question? 1."Where is the pain located?" 2."Are you having any nausea?" 3."Are you allergic to any medications?" 4."Do you have your nitroglycerin with you?"

1. If a client complains of chest pain, the initial assessment question would be to ask the client about the pain intensity, location, duration, and quality. Although options 2, 3, and 4 all may be components of the assessment, none of these questions would be the initial assessment question with this client.

The nurse has provided self-care activity instructions to a client after insertion of an automatic internal cardioverter-defibrillator (AICD). The nurse determines that further instruction is needed if the client makes which statement? 1."I can perform activities such as swimming, driving, or operating heavy equipment as I need to." 2."I need to avoid doing anything that could involve rough contact with the AICD insertion site." 3."I should try to avoid doing strenuous things that would make my heart rate go up to or above the rate cutoff on the AICD." 4."I should keep away from electromagnetic sources such as transformers, large electrical generators, metal detectors, and I shouldn't lean over running motors."

1. Post discharge instructions typically include avoiding tight clothing or belts over AICD insertion sites; rough contact with the AICD insertion site; and electromagnetic fields such as with electrical transformers, radio/TV/radar transmitters, metal detectors, and running motors of cars or boats. Clients also must alert health care providers (HCP) or dentists to the presence of the device because certain procedures such as diathermy, electrocautery, and magnetic resonance imaging may need to be avoided to prevent device malfunction. Clients should follow the specific advice of a HCP regarding activities that are potentially hazardous to self or others, such as swimming, driving, or operating heavy equipment.

A client with a history of angina pectoris tells the nurse that chest pain usually occurs after going up two flights of stairs or after walking four blocks. What type of angina should the nurse determine that the client is experiencing? 1.Stable 2.Variant 3.Unstable 4.Intractable

1. Stable angina is triggered by a predictable amount of effort or emotion. Variant angina is triggered by coronary artery spasm; the attacks are of longer duration than in classic angina and tend to occur early in the day and at rest. Unstable angina is triggered by an unpredictable amount of exertion or emotion and may occur at night; the attacks increase in number, duration, and severity over time. Intractable angina is chronic and incapacitating and is refractory to medical therapy.

The home care nurse has taught a client with a problem of inadequate cardiac output about helpful lifestyle adaptations to promote health. Which statement by the client best demonstrates an understanding of the information provided? 1."I will eat enough daily fiber to prevent straining at stool." 2."I will try to exercise vigorously to strengthen my heart muscle." 3."I will drink 3000 to 3500 mL of fluid daily to promote good kidney function." 4."Drinking 2 to 3 oz of liquor each night will promote blood flow by enlarging blood vessels."

1. Standard home care instructions for a client with this problem include, among others, lifestyle changes such as decreased alcohol intake, avoiding activities that increase the demands on the heart, instituting a bowel regimen to prevent straining and constipation, and maintaining fluid and electrolyte balance. Consuming 3000 to 3500 mL of fluid and exercising vigorously will increase the cardiac workload.

The nurse is developing a plan of care for a client who will be admitted to the hospital with a diagnosis of deep vein thrombosis (DVT) of the right leg. The nurse develops the plan, expecting that the health care provider will most likely prescribe which option? 1.Maintain bed rest. 2.Maintain the affected leg in a dependent position. 3.Administer an opioid analgesic every 4 hours around the clock. 4.Apply cool packs to the affected leg for 20 minutes every 4 hours.

1. Standard management for the client with DVT includes bed rest; limb elevation; relief of discomfort with warm, moist heat; and analgesics as needed. Ambulation is contraindicated because such activity can cause the thrombus to dislodge and travel to the lungs. Opioid analgesics are not required to relieve pain, and pain normally is relieved with acetaminophen (Tylenol).

A nurse is caring for a client who has lost a significant amount of blood as a result of complications of a surgical procedure. The nurse understands that which client assessment will provide the earliest indication of new decreases in fluid volume? 1.Pulse rate 2.Blood pressure (BP) 3.Assessment for edema 4.Lung auscultation for crackles

1. The cardiac output is determined by the volume of the circulating blood, the pumping action of the heart, and the tone of the vascular bed. Early decreases in fluid volume are compensated for by an increase in the pulse rate. Options 3 and 4 indicate an increase in fluid volume. Although the BP will decrease, it is not the earliest indicator.

The nurse is caring for a client with cardiac disease who has been placed on a cardiac monitor. The nurse notes that the client has developed atrial fibrillation and has a ventricular rate of 150 beats/min. The nurse should next assess the client for which finding? 1.Hypotension 2.Flat neck veins 3.Complaints of nausea 4.Complaints of headache

1. The client with uncontrolled atrial fibrillation with a ventricular rate greater than 100 beats/min is at risk for low cardiac output owing to loss of atrial kick. The nurse assesses the client for palpitations, chest pain or discomfort, hypotension, pulse deficit, fatigue, weakness, dizziness, syncope, shortness of breath, and distended neck veins.

A client has experienced a myocardial infarction. The nurse plans care for the client, knowing that the person's chest pain is caused by tissue hypoxia in which layer of the heart? 1.Myocardium 2.Endocardium 3.Parietal pericardium 4.Visceral pericardium

1. The myocardial layer of the heart is damaged when a client experiences a myocardial infarction. This is the middle layer that contains the striated muscle fibers responsible for the contractile force of the heart. The endocardium is the thin inner layer of cardiac tissue. The parietal pericardium and visceral pericardium are outer layers that protect the heart from injury and infection.

A client with no history of heart disease has experienced acute myocardial infarction and has been given thrombolytic therapy with tissue plasminogen activator. What assessment finding should the nurse identify as the most likely indicator that the client is experiencing complications of this therapy? 1.Tarry stools 2.Nausea and vomiting 3.Orange-colored urine 4.Decreased urine output

1. Thrombolytic agents are used to dissolve existing thrombi, and the nurse should monitor the client for obvious or occult signs of bleeding. This includes assessment for obvious bleeding within the gastrointestinal (GI) tract, urinary system, and skin. It also includes Hematest testing of secretions for occult blood. The correct option is the only one that indicates the presence of blood.

A client is admitted to the hospital with a diagnosis of pericarditis. The nurse should assess the client for which manifestation that differentiates pericarditis from other cardiopulmonary problems? 1.Anterior chest pain 2.Pericardial friction rub 3.Weakness and irritability 4.Chest pain that worsens on inspiration

2. A pericardial friction rub is heard when inflammation of the pericardial sac is present during the inflammatory phase of pericarditis. Anterior chest pain may be experienced with angina pectoris and myocardial infarction. Weakness and irritability are nonspecific complaints and could accompany a wide variety of disorders. Chest pain that worsens on inspiration is characteristic of both pericarditis and pleurisy.

The nurse is concerned about the adequacy of peripheral tissue perfusion in the post-cardiac surgery client. Which action should the nurse include within the plan of care for this client? 1.Use the knee-gatch on the bed. 2.Cover the legs lightly when sitting in a chair. 3.Encourage the client to cross legs when sitting in a chair. 4.Provide pillows for the client to place under the knees as desired.

2. Covering the legs with a light blanket during sitting promotes warmth and vasodilation of the leg vessels. The nurse plans postoperative measures to prevent venous stasis. These include applying elastic stockings or leg wraps, use of pneumatic compression boots, and discouraging leg-crossing. Clients should be encouraged to perform passive and active range of motion exercises. The knee gatch on the bed and pillows under the knees should be avoided because it places pressure on the blood vessels in the popliteal area, impeding venous return.

The nurse is developing a plan of care for a client with varicose veins in whom skin breakdown occurred over the varicosities as a result of secondary infection. Which is a priority intervention? 1.Keep the legs aligned with the heart. 2.Elevate the legs higher than the heart. 3.Clean the skin with alcohol every hour. 4.Position the client onto the side every shift.

2. In the client with a venous disorder, the legs are elevated above the level of the heart to assist with the return of venous blood to the heart. Alcohol is very irritating and drying to tissues and should not be used in areas of skin breakdown. Option 4 specifies infrequent care intervals, so it is not the priority intervention.

The nurse is preparing discharge instructions for a client with Raynaud's disease. The nurse should plan to provide which instruction to the client? 1.Use nail polish to protect the nail beds from injury. 2.Stop smoking because it causes cutaneous vasospasm. 3.Wear gloves for all activities involving use of both hands. 4.Always wear warm clothing even in warm climates to prevent vasoconstriction.

2. Raynaud's disease is peripheral vascular disease characterized by abnormal vasoconstriction in the extremities. Smoking cessation is one of the most important lifestyle changes that the client must make. The nurse should emphasize the effects of tobacco on the blood vessels and the principles involved in stopping smoking. The nurse needs to provide information to the client about smoking cessation programs available in the community. Options 1 and 4 are incorrect. It is not necessary to wear gloves for all activities.

A client's electrocardiogram (ECG) strip shows atrial and ventricular rates of 70 complexes/min. The PR interval is 0.16 second, the QRS complex measures 0.06 second, and the PP interval is slightly irregular. How should the nurse interpret this rhythm? 1.Sinus tachycardia 2.Sinus dysrhythmia 3.Sinus bradycardia 4.Normal sinus rhythm

2. Sinus dysrhythmia has all of the characteristics of normal sinus rhythm except for the presence of an irregular PP interval. This irregular rhythm occurs because of phasic changes in the rate of firing of the sinoatrial node, which may occur with vagal tone and with respiration. Cardiac output is not affected.

A client recovering from pulmonary edema is preparing for discharge. What should the nurse plan to teach the client to do to manage or prevent recurrent symptoms after discharge? 1.Sleep with the head of bed flat. 2.Weigh himself or herself on a daily basis. 3.Take a double dose of the diuretic if peripheral edema is noted. 4.Withhold prescribed digoxin (Lanoxin) if slight respiratory distress occurs.

2. The client can best determine fluid status at home by weighing himself or herself on a daily basis. Increases of 2 to 3 lb in a short period are reported to the health care provider (HCP). The client should sleep with the head of the bed elevated. During recumbent sleep, fluid (which has seeped into the interstitium with the assistance of the effects of gravity) is rapidly reabsorbed into the systemic circulation. Sleeping with the head of the bed flat is therefore avoided. The client does not modify medication dosages without consulting the HCP.

A client complains of calf tenderness, and thrombophlebitis is suspected. The nurse should next assess the client for which finding? 1.Bilateral edema 2.Increased calf circumference 3.Diminished distal peripheral pulses 4.Coolness and pallor of the affected limb

2. The client with thrombophlebitis, also known as deep vein thrombosis, exhibits redness or warmth of the affected leg, tenderness at the site, possibly dilated veins (if superficial), low-grade fever, edema distal to the obstruction, and increased calf circumference in the affected extremity. Peripheral pulses are unchanged from baseline because this is a venous, not an arterial, problem.

A hospitalized client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned and takes action, knowing that this level could ultimately lead to which complication? 1.Stroke 2.Cardiac arrest 3.High blood pressure 4.Urinary stone formation

2. The normal calcium level is 8.6 to 10 mg/dL. A low calcium level could lead to severe ventricular dysrhythmias, prolonged QT interval, and ultimately cardiac arrest. Calcium is needed by the heart for contraction. Calcium ions move across cell membranes into cardiac cells during depolarization and move back during repolarization. Depolarization is responsible for cardiac contraction. Options 1 and 3 are unrelated to calcium levels. Elevated calcium levels can lead to urinary stone formation. The nurse would take action and contact the health care provider when a calcium level is abnormal.

A nurse who is auscultating a 56-year-old client's apical heart rate before administering digoxin (Lanoxin) notes that the heart rate is 52 beats/min. The nurse should make which interpretation about this information? 1.Normal, because of the client's age 2.Abnormal, requiring further assessment 3.Normal, as a result of the effects of digoxin 4.Normal, because this is the reason the client is receiving digoxin

2. The normal heart rate is 60 to 100 beats/min in an adult. On auscultating a heart rate that is less than 60 beats/min, the nurse would not administer the digoxin and would report the finding to the health care provider. Digoxin increases the strength and contraction of the heart; it is not used to treat low heart rates. If a low heart rate is noted in a client taking digoxin, the medication is withheld and the health care provider is notified. Options 1, 3, and 4 are incorrect interpretations because the heart rate of 52 beats/min is not normal.

A client with angina complains that the anginal pain is prolonged and severe and occurs at the same time each day, most often at rest in the absence of precipitating factors. How would the nurse best describe this type of anginal pain? 1.Stable angina 2.Variant angina 3.Unstable angina 4.Nonanginal pain

2. Variant angina, or Prinzmetal's angina, is prolonged and severe and occurs at the same time each day, most often at rest. Stable angina is induced by exercise and relieved by rest or nitroglycerin tablets. Unstable angina occurs at lower levels of activity or at rest, is less predictable, and is often a precursor of myocardial infarction.

2. Ventricular fibrillation is characterized by the absence of P waves and QRS complexes. The rhythm is instantly recognizable by the presence of coarse or fine fibrillatory waves on the cardiac monitoring screen. Sinus tachycardia has a recognizable P wave and QRS. Ventricular tachycardia is a regular pattern of wide QRS complexes. PVCs appear as irregular beats within a rhythm.

A female client calls the nurse at the clinic and reports that ever since the vein ligation and stripping procedure was performed, she has been experiencing a sensation as though the affected leg is falling asleep. The nurse should make which response to the client? 1."Apply warm packs to the leg." 2."Keep the leg elevated as much as possible." 3."Contact your health care provider right away to report this problem." 4."This normally occurs after surgery and will subside when the edema goes down."

3. A sensation of pins and needles or feeling as though the surgical limb is falling asleep may indicate temporary or permanent nerve damage after surgery. The saphenous vein and the saphenous nerve run close together, and damage to the nerve will produce paresthesias. Options 1, 2, and 4 are inaccurate responses. An alternative to surgery is endovenous ablation of the saphenous vein. Ablation involves the insertion of a catheter that emits energy. This causes collapse and sclerosis of the vein. Potential complications include bruising, tightness along the vein, recanalization (reopening of the vein), and paresthesia. Endovenous ablation also may be done in combination with saphenofemoral ligation or phlebectomy. Transilluminated powdered phlebectomy involves the use of a powdered resector to destroy the varices and then removes the pieces via aspiration.

3. After angioplasty, the client needs to be instructed regarding the specific dietary restrictions that must be followed. Making the recommended dietary and lifestyle changes will assist in preventing further atherosclerosis. Abrupt closure of the artery can occur if the dietary and lifestyle recommendations are not followed. Cigarette smoking needs to be stopped. An angioplasty does not repair the heart.

A client who has been exercising in a gymnasium stops to measure his pulse and places his fingers over both carotid arteries simultaneously. A nurse exercising nearby is correct when the nurse cautions him to check the pulse on only one side, primarily for which reason? 1.It is unnecessary to use both hands. 2.The client could occlude the trachea. 3.The heart rate and blood pressure could drop. 4.Feeling dual pulsations may lead to an incorrect measurement.

3. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to drop reflexively. In addition, the manual pressure could interfere with the flow of blood to the brain, causing possible dizziness and syncope.

The nurse should document that these findings identify which type of ulcer? 1.A stage 1 ulcer 2.A vascular ulcer 3.An arterial ulcer 4.A venous stasis ulcer

3. Arterial ulcers have a pale deep base and are surrounded by tissue that is cool with trophic changes such as dry skin and loss of hair. Arterial ulcers are caused by tissue ischemia from inadequate arterial supply of oxygen and nutrients. A stage 1 ulcer indicates a reddened area with an intact skin surface. A venous stasis ulcer (vascular) has a dark red base and is surrounded by brown skin with local edema. This type of ulcer is caused by the accumulation of waste products of metabolism that are not cleared, as a result of venous congestion.

The nurse interprets that this client's behavior is most likely related to which problem? 1.Anxiety related to the need to make lifestyle changes 2.Boredom resulting from having already learned the material 3.An attempt to ignore or deny the need to make lifestyle changes 4.Lack of understanding of the material provided at the teaching session and embarrassment about asking questions

3. Denial is a defense mechanism that allows the client to minimize a threat that may be manifested by refusal to discuss what has happened. Denial is a common early reaction associated with chest discomfort, angina, or myocardial infarction (MI). Anxiety usually is manifested by symptoms of sympathetic nervous system arousal. No data are provided in the question that would lead the nurse to interpret the client's behavior as boredom or as either understanding or not understanding the material provided at the teaching session.

A hospitalized client has been diagnosed with heart failure as a complication of hypertension. In explaining the disease process to the client, the nurse identifies which chamber of the heart as primarily responsible for the symptoms? 1.Left atrium 2.Right atrium 3.Left ventricle 4.Right ventricle

3. Hypertension increases the workload of the left ventricle because the ventricle has to pump the stroke volume against increased resistance (afterload) in the major blood vessels. Over time this causes the left ventricle to fail, leading to signs and symptoms of heart failure. Options 1, 2, and 4 are not the chambers that are primarily responsible for this disease process although these chambers may become affected as the disease becomes more chronic.

A nurse is reinforcing instructions to a hospitalized client with heart block about the fundamental concepts regarding the cardiac rhythm. The nurse explains to the client that the normal site in the heart responsible for initiating electrical impulses is which site? 1.Bundle of His 2.Purkinje fibers 3.Sinoatrial (SA) node 4.Atrioventricular (AV) node

3. The SA node is responsible for initiating electrical impulses that are conducted through the heart. The impulse leaves the SA node and travels down through internodal and interatrial pathways to the AV node. From there, impulses travel through the bundle of His to the right and left bundle branches and then to the Purkinje fibers. This group of specialized cardiac cells is referred to as the cardiac conduction system. The ability of this specialized tissue to generate its own impulses is called automaticity.

The nurse should include which item in the instructions? 1.Driving is permitted so long as the lap and shoulder seat belts are worn. 2.Lifting should be restricted to objects that do not weigh more than 25 pounds. 3.Use the arms for balance, not weight support, when getting out of bed or a chair. 4.Activities that involve straining may be resumed so long as they do not cause pain.

3. The client is taught to use the arms for balance, but not weight support, to avoid the effects of straining on the sternum. Typical discharge activity instructions for the first 6 weeks include instructing the client to lift nothing heavier than 5 pounds, to not drive, and to avoid any activities that cause straining. These limitations are to allow for sternal healing, which takes approximately 6 weeks.

A client with coronary artery disease is scheduled to have a diagnostic exercise stress test. Which instruction should the nurse plan to provide to the client about this procedure? 1.Eat breakfast just before the procedure. 2.Wear firm, rigid shoes, such as workboots. 3.Wear loose clothing with a shirt that buttons in front. 4.Avoid cigarettes for 30 minutes before the procedure.

3. The client should wear loose, comfortable clothing for the procedure. Electrocardiogram (ECG) lead placement is enhanced if the client wears a shirt that buttons in the front. The client should receive nothing by mouth after bedtime or for a minimum of 2 hours before the test. The client should wear rubber-soled, supportive shoes, such as athletic training shoes. The client should avoid smoking, alcohol, and caffeine on the day of the test. Inadequate or incorrect preparation can interfere with the test, with the potential for a false-positive result.

A client has developed uncontrolled atrial fibrillation with a ventricular rate of 150 beats/min. What manifestation should the nurse observe for when performing the client's focused assessment? 1.Flat neck veins 2.Nausea and vomiting 3.Hypotension and dizziness 4.Clubbed fingertips and headache

3. The client with uncontrolled atrial fibrillation with a ventricular rate greater than 100 beats/min is at risk for low cardiac output due to loss of atrial kick. The nurse assesses the client for palpitations, chest pain or discomfort, hypotension, pulse deficit, fatigue, weakness, dizziness, syncope, shortness of breath, and distended neck veins.

A client who is beginning an exercise program asks the nurse why his heart "feels like it's pounding" when he is exercising vigorously. In formulating a response, the nurse understands that this effect occurs because of the client's primary need for which increased cardiac response? 1.Pulse rate 2.Cardiac index 3.Cardiac output 4.Stroke volume

3. The client's symptoms are the direct result of the body's attempt to meet the metabolic demands generated during exercise. An adequate cardiac output is needed to maintain perfusion to the vital organs of the body. With exercise, these demands increase, and the heart must beat faster (increased heart rate) and harder (increased stroke volume) to meet them. Cardiac index is an artificial number used to determine the adequacy of the cardiac output for a given individual. It is calculated by adjusting the cardiac output for body surface area.

The nurse working in a long-term care facility is assessing a client who is experiencing chest pain. The nurse should interpret that the pain is most likely caused by myocardial infarction (MI) on the basis of what assessment finding? 1.The client is not experiencing dyspnea. 2.The client is not experiencing nausea or vomiting. 3.The pain has not been relieved by rest and nitroglycerin tablets. 4.The client says the pain began while she was trying to open a stuck dresser drawer.

3. The pain of MI is not relieved by rest and nitroglycerin and requires opioid analgesics, such as morphine sulfate, for relief. The pain of angina may radiate to the left shoulder, arm, neck, or jaw. It often is precipitated by exertion or stress, is accompanied by few associated symptoms, and is relieved by rest and nitroglycerin. The pain of MI also may radiate to the left arm, shoulder, jaw, and neck. It typically begins spontaneously, lasts longer than 30 minutes, and frequently is accompanied by associated symptoms (such as nausea, vomiting, dyspnea, diaphoresis, or anxiety).

A hospitalized client is experiencing a decrease in blood pressure. The nurse plans care for the client, knowing that this change will have which primary effect on his or her heart? 1.Decreased heart rate 2.Increased contractility 3.Decreased myocardial blood flow 4.Increased resistance to electrical stimulation

3. The primary effect of a decrease in blood pressure is reduced blood flow to the myocardium. This in turn decreases oxygenation of the cardiac tissue. Cardiac tissue is likely to become more excitable or irritable in the presence of hypoxia. Correspondingly, the heart rate is likely to increase, not decrease, in response to this change. The effects of tissue ischemia lead to decreased contractility over time.

The nurse is trying to determine the ability of the client with myocardial infarction (MI) to manage independently at home after discharge. Which statement by the client is the strongest indicator of the potential for difficulty after discharge? 1."I need to start exercising more to improve my health." 2."I will be sure to keep my appointment with the cardiologist." 3."I don't have anyone to help me with doing heavy housework at home." 4."I think I have a good understanding of what all my medications are for."

3. To ensure the best outcome, clients should be able to comply with instructions related to activity, diet, medications, and follow-up health care on discharge from the hospital after an MI. All of the options except the correct option indicate that the client will be successful in these areas.

A client with a history of hypertension has been prescribed triamterene (Dyrenium). The nurse determines that the client understands the effect of this medication on the diet if the client states to avoid which fruit? 1.Apples 2.Pears 3.Bananas 4.Cranberries

3. Triamterene is a potassium-retaining diuretic, so the client should avoid foods high in potassium. Fruits that are naturally higher in potassium include avocados, bananas, fresh oranges, mangos, nectarines, papayas, and prunes.

The home health nurse makes a home visit to a client who has an implantable cardioverter-defibrillator (ICD) and reviews the instructions concerning pacemakers and dysrhythmias with the client. Which client statement indicates that further teaching is necessary? 1."If I feel an internal defibrillator shock, I should sit down." 2."I won't be able to have a magnetic resonance imaging test (MRI)." 3."My wife knows how to call the emergency medical services (EMS) if I need it." 4."I can stop taking my antidysrhythmic medicine now because I have a pacemaker."

4. Clients with an ICD usually continue to receive antidysrhythmic medications after discharge from the hospital. The nurse should stress the importance of continuing to take these medications as prescribed. The nurse should provide clear instructions about the purposes of the medications, dosage schedule, and side effects or adverse effects to report. Clients should sit down if they feel an internal defibrillator shock. They cannot have an MRI because of the possible magnetic properties of the device. Also, knowledge of how to reach EMS is important.

A client admitted to the hospital with coronary artery disease complains of dyspnea at rest. The nurse caring for the client uses which item as the best means to monitor respiratory status on an ongoing basis? 1. Apnea monitor 2.Oxygen flowmeter 3.Telemetry cardiac monitor 4.Oxygen saturation monitor

4. Dyspnea in the cardiac client often is accompanied by hypoxemia. Hypoxemia can be detected by an oxygen saturation monitor, especially if it is used continuously. An apnea monitor detects apnea episodes, such as when the client has stopped breathing briefly. An oxygen flowmeter is part of the setup for delivering oxygen therapy. Cardiac monitors detect dysrhythmias.

A client who had coronary artery bypass surgery states to the home health nurse: "get so frustrated. I can't even do my gardening." The nurse then assesses the client for activity level since the surgery. Which client statement indicates a need for further teaching? 1."I pace my activities throughout the day." 2."I plan regular rest periods during the day." 3."I avoid outdoor physical activity during the heat of the day." 4."I try to walk immediately after lunch, after I've finished my morning housecleaning."

4. Exercise is an integral part of the rehabilitation program. It is necessary for optimal physiological functioning and psychological well-being. Postoperative physical rehabilitation must be progressive with planned periods of rest. Exercise tolerance is judged by the client's response, such as heart rate and endurance. Planning regular rest periods, pacing activities, and avoiding outdoor activities during the heat of the day are appropriate client activities. The correct option lacks planned periods of rest, and the client has grouped too many activities in a brief period of time, which will decrease endurance. Also, exercise after meals can decrease the client's tolerance because of shunting of blood to the gastrointestinal tract for digestion.

The nurse is performing a health screening on a 54-year-old client. The client has a blood pressure of 118/78 mm Hg, total cholesterol level of 190 mg/dL, and fasting blood glucose level of 184 mg/dL. The nurse interprets this to mean that the client has which modifiable risk factor for coronary artery disease (CAD)? 1.Age 2.Hypertension 3.Hyperlipidemia 4.Glucose intolerance

4. Hypertension, cigarette smoking, and hyperlipidemia are modifiable risk factors that are predictors of CAD. Glucose intolerance, obesity, and response to stress are contributing modifiable risk factors to CAD. Age greater than 40 years is a nonmodifiable risk factor. The nurse places priority on risk factors that can be modified. In this scenario, the abnormal value is the fasting blood glucose level, indicating glucose intolerance as the priority risk factor.

A nurse is assigned to the care of a client hospitalized with a diagnosis of hypothermia. The nurse anticipates that the client will exhibit which findings on assessment of vital signs? 1.Increased heart rate and increased blood pressure 2.Increased heart rate and decreased blood pressure 3.Decreased heart rate and increased blood pressure 4.Decreased heart rate and decreased blood pressure

4. Hypothermia decreases the heart rate and the blood pressure because the metabolic needs of the body are reduced in this condition. With fewer metabolic needs, the workload of the heart decreases, resulting in decreased heart rate and blood pressure. Therefore, options 1, 2, and 3 are incorrect.

A client with a complete heart block has had a permanent demand ventricular pacemaker inserted. The nurse assesses for proper pacemaker function by examining the electrocardiogram (ECG) strip for the presence of pacemaker spikes at what point? 1.Before each P wave 2.Just after each P wave 3.Just after each T wave 4.Before each QRS complex

4. If a ventricular pacemaker is functioning properly, there will be a pacer spike followed by a QRS complex. An atrial pacemaker spike precedes a P wave if an atrial pacemaker is implanted. A demand pacemaker fires only when needed and should therefore discharge only when no electrical activity is occurring in the client's own heart.

4. It is common for the client to feel fatigued after the cardiac catheterization procedure. A local anesthetic is used, so little to no pain is experienced with catheter insertion. General anesthesia is not used. Other preprocedure teaching points include the fact that the procedure is done in a darkened cardiac catheterization room. The x-ray table is hard and may be tilted periodically, and the procedure may take 1 to 2 hours. The client may feel various sensations with catheter passage and dye injection.

Metformin (Glucophage)

4. Metformin (Glucophage) needs to be withheld 24 hours before and for 48 hours after cardiac catheterization because of the injection of contrast medium during the procedure. If the contrast medium affects kidney function, with metformin in the system, the client would be at increased risk for lactic acidosis. The medications in the remaining options do not need to be withheld 24 hours before and 48 hours after cardiac catheterization.

The nurse should address with the client which most important measure to ensure client safety? 1.Assessing pain 2.Administering vasodilators 3.Avoiding over-the-counter medications 4.Moving slowly from a sitting to a standing position

4. Orthostatic changes can occur in the client with cardiomyopathy as a result of venous return obstruction. Sudden changes in blood pressure may lead to falls. Vasodilators normally are not prescribed for the client with cardiomyopathy. Options 1 and 3, although important, are not directly related to the issue of safety.

4. PVCs are considered dangerous when they are frequent (more than 6 per minute), occur in pairs or couplets, are multifocal (multiform), or fall on the T wave. In each of these instances, the client's cardiac rhythm is likely to degenerate into ventricular tachycardia or ventricular fibrillation, both of which are potentially deadly dysrhythmias.

A client is having frequent premature ventricular contractions. The nurse should place priority on assessment of which item? 1.Sensation of palpitations 2.Causative factors, such as caffeine 3.Precipitating factors, such as infection 4.Blood pressure and oxygen saturation

4. Premature ventricular contractions can cause hemodynamic compromise. Therefore, the priority is to monitor the blood pressure and oxygen saturation. The shortened ventricular filling time can lead to decreased cardiac output. The client may be asymptomatic or may feel palpitations. Premature ventricular contractions can be caused by cardiac disorders, states of hypoxemia, or by any number of physiological stressors, such as infection, illness, surgery, or trauma, and by intake of caffeine, nicotine, or alcohol.

The nurse is performing an admission assessment on a client with a diagnosis of Raynaud's disease. How should the nurse assess for this disease? 1.Checking for a rash on the digits 2.Observing for softening of the nails or nail beds 3.Palpating for a rapid or irregular peripheral pulse 4.Palpating for diminished or absent peripheral pulses

4. Raynaud's disease produces closure of the small arteries in the distal extremities in response to cold, vibration, or external stimuli. Palpation for diminished or absent peripheral pulses checks for interruption of circulation. Skin changes include hair loss, thinning or tightening of the skin, and delayed healing of cuts or injuries. The nails grow slowly, become brittle or deformed, and heal poorly around the nail beds when infected. Although palpation of peripheral pulses is correct, a rapid or irregular pulse would not be noted.

A client with a diagnosis of varicose veins is scheduled for treatment by sclerotherapy and asks the nurse to describe the procedure. Which response should the nurse make? 1."It involves tying off the veins so that circulation is redirected in another area." 2."It involves surgically removing the varicosity, so anesthesia will be required." 3."It involves tying off the veins to prevent sluggishness of blood from occurring." 4."It involves injecting an agent into the vein to damage the vein wall and close it off."

4. Sclerotherapy is the injection of a sclerosing agent into a varicosity. The agent damages the vessel and causes aseptic thrombosis, which results in vein closure. With no blood flow through the vessel, distention will not occur. The surgical procedure for varicose veins is vein ligation and stripping. This procedure involves tying off the varicose vein and large tributaries and then removing the vein with the use of a hook and wires applied through multiple small incisions in the leg. Other treatments include the application of radiofrequency (RF) energy, in which the vein is heated from the inside by the RF energy and shrinks; collateral veins nearby take over. Laser treatment is another alternative to surgery; in this treatment a laser fiber is used to heat and close the main vessel that is contributing to the varicosity.

The nurse determines that the HCP is referring to which arteries? 1.Circumflex coronary artery 2.Right coronary artery (RCA) 3.Posterior descending coronary artery (PDA) 4.Left anterior descending coronary artery (LAD)

4. The LAD bifurcates from the left main coronary artery to supply the anterior wall of the left ventricle and a few other structures. The circumflex coronary artery bifurcates from the left coronary artery and supplies the left atrium and the lateral wall of the left ventricle. The RCA supplies the right side of the heart, including the right atrium and right ventricle. The PDA supplies the posterior wall of the heart.

4. The client recovering from cardiogenic shock secondary to a myocardial infarction will require a progressive rehabilitation related to physical activity. The heart requires several months to heal from an uncomplicated myocardial infarction. The complication of cardiogenic shock increases the recovery period for healing. Paced activities with planned rest periods will decrease the chance of experiencing angina or delayed healing. It is best to allow the meal to settle prior to activity in order to improve circulation to the heart during exercise. Epigastric pain or a weight gain of 8 pounds is significant and should be reported to the health care provider, at which point follow-up should occur.

4. The client should alert any HCP about the history of infective endocarditis before any procedure that involves instrumentation. The HCP should place the client on prophylactic antibiotics if an invasive procedure is needed. Antibiotics should be taken for the full course of therapy. The client should notify the HCP if chest pain worsens or if dyspnea or other symptoms occur. The client should use a soft toothbrush and floss carefully to avoid any trauma to the gums, which could provide a portal of entry for bacterial infection.

The nurse is caring for a client who has been hospitalized with a diagnosis of angina pectoris. The client is receiving oxygen via nasal cannula at 2 L/min. The client asks why the oxygen is necessary. The nurse should provide which information to the client? 1.Oxygen has a calming effect. 2.Oxygen will prevent the development of any thrombus. 3.Oxygen dilates the blood vessels so that they can supply more nutrients to the heart muscle. 4.The pain of angina pectoris occurs because of a decreased oxygen supply to heart cells.

4. The pain associated with angina results from ischemia of myocardial cells. The pain often is precipitated by activity that places more oxygen demand on heart muscle. Supplemental oxygen will help to meet the added demands on the heart muscle. Oxygen does not dilate blood vessels or prevent thrombus formation and does not directly calm the client.

The nurse is discussing smoking cessation with a client diagnosed with coronary artery disease (CAD). Which statement should the nurse make to try to motivate the client to quit smoking? 1."None of the cardiovascular effects are reversible, but quitting might prevent lung cancer." 2."Because most of the damage has already been done, it will be all right to cut down a little at a time." 3."If you totally quit smoking right now, you can cut your cardiovascular risk to zero within a year." 4."If you quit now, your risk of cardiovascular disease will decrease to that of a nonsmoker in 3 to 4 years."

4. The risks to the cardiovascular system from smoking are noncumulative and are not permanent. Three to 4 years after cessation, a client's cardiovascular risk is similar to that of a person who never smoked. In addition, tobacco use and passive smoking from "secondhand smoke" (also called environmental smoke) substantially reduce blood flow in the coronary arteries. Options 1, 2, and 3 are incorrect.

A client recovering from an exacerbation of left-sided heart failure is experiencing activity intolerance. Which change in vital signs during activity would be the best indicator that the client is tolerating mild exercise? 1.Oxygen saturation decreased from 96% to 91%. 2.Pulse rate increased from 80 to 104 beats per minute. 3.Blood pressure decreased from 140/86 to 112/72 mm Hg. 4.Respiratory rate increased from 16 to 19 breaths per minute.

4. Vital signs that remain near baseline indicate good cardiac reserve with exercise. Only the respiratory rate remains within the normal range. Additionally, it reflects a minimal increase. A pulse rate increase to a rate over 100 beats per minute during mild exercise does not show tolerance, nor does a 5% decrease in oxygen saturation levels. In addition, blood pressure decreasing by more than 10 mm Hg is not a sign indicating tolerance of activity.

4. When a client has HF, the goal is to reduce fluid accumulation. One way that this is accomplished is through sodium reduction. Ham (and most cold cuts), cheese, and potato chips are high in sodium. Daily weighing is an appropriate intervention to help the client monitor fluid overload. Most fresh fruits and vegetables are low in sodium.
