Prep U-Chapter 30 Assessment and Management of Patients With Vascular Disorders and Problems of Peripheral Circulation

In order to be effective, percutaneous transluminal coronary angioplasty (PTCA) must be performed within what time frame, beginning with arrival at the emergency department after diagnosis of myocardial infarction? a) 30 minutes b) 6 to 12 months c) 9 days d) 60 minutes

60 minutes The 60-minute interval is known as "door-to-balloon time" for performance of PTCA on a diagnosed MI patient. The 30-minute interval is known as "door-to-needle time" for administration of thrombolytics post MI. The time frame of 9 days refers to the time for onset of vasculitis after administration of streptokinase for thrombolysis in an acute MI patient. The 6 to 12 month time frame refers to the time period during which streptokinase will not be used again in the same patient for acute MI.

The nurse explains to a patient that the primary cause of a varicose vein is: a) Venous occlusion. b) Phlebothrombosis. c) An incompetent venous valve. d) Venospasm.

An incompetent venous valve. Varicose veins are abnormally dilated, tortuous, superficial veins caused by incompetent venous valves.

Which aneurysm occurs as a result of infection at arterial suture or graft sites?

Anastomotic

Which aneurysm occurs as a result of infection at arterial suture or graft sites? a) Dissecting b) Anastomotic c) False d) Saccular

Anastomotic An anastomotic aneurysm occurs as a result of infection at arterial suture or graft sites. Dissection results from a rupture in the intimal layer, resulting in bleeding between the intimal and medial layers of the arterial wall. Saccular aneurysms collect blood in the weakened outpouching. In a false aneurysm, the mass is actually a pulsating hematoma

A client has been diagnosed with peripheral arterial occlusive disease. Which of the following instructions is appropriate for the nurse to give the client for promoting circulation to the extremities? a. Keep the extremities elevated slightly. b. Participate in a regular walking program. c. Massage the calf muscles if pain occurs. d. Use a heating pad to promote warmth.

Participate in a regular walking program. Clients diagnosed with peripheral arterial occlusive disease should be encouraged to participate in a regular walking program to help develop collateral circulation. They should be advised to rest if pain develops and to resume activity when pain subsides. Extremities should be kept in a dependent position to promote circulation; elevation of the extremities will decrease circulation. Heating pads should not be used by anyone with impaired circulation to avoid burns. Massaging the calf muscles will not decrease pain. Intermittent claudication subsides with rest.

Which of the following is the most effective intervention for preventing progression of vascular disease? a) Use neutral soaps b) Risk factor modification c) Avoid trauma d) Wear sturdy shoes

Risk factor modification

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions?

Stabilizing heart rate and blood pressure and easing anxiety

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions? Increasing blood pressure and reducing mobility Decreasing blood pressure and increasing mobility Increasing blood pressure and monitoring fluid intake and output Stabilizing heart rate and blood pressure and easing anxiety

Stabilizing heart rate and blood pressure and easing anxiety

A nurse is reviewing self-care measures for a client with peripheral vascular disease. Which statement indicates proper self-care measures?

"I have my wife look at the soles of my feet each day."

A nurse is reviewing self-care measures for a client with peripheral vascular disease. Which statement indicates proper self-care measures? "I walk only to the mailbox in my bare feet." "I have my wife look at the soles of my feet each day." "I like to soak my feet in the hot tub every day." "I stopped smoking and use only chewing tobacco."

"I have my wife look at the soles of my feet each day."

"I have my wife look at the soles of my feet each day." A client with peripheral vascular disease should examine his feet daily for redness, dryness, or cuts. If a client isn't able to do this examination on his own, then a caregiver or family member should help him. A client with peripheral vascular disease should avoid hot tubs because decreased sensation in the feet may make him unable to tell if the water is too hot. The client should always wear shoes or slippers on his feet when he is out of bed to help minimize trauma to the feet. Any type of nicotine, whether it's from cigarettes or smokeless tobacco, can cause vasoconstriction and further decrease blood supply to the extremities.

The nurse completes discharge teaching for a patient following a femoral-to-popliteal bypass graft. What response by the patient would indicate teaching was effective? a) "It will important for me to sit at the kitchen table to promote better breathing." b) "I can now stop taking my Lipitor because my leg is fixed." c) "I can stop the exercises that were started in the hospital once I return home." d) "I will call if I develop any coldness, numbness, tingling, or pain in the surgical leg."

"I will call if I develop any coldness, numbness, tingling, or pain in the surgical leg." The nurse ensures that the patient has the knowledge and ability to assess for any postoperative complications such as infection, occlusion of the artery or graft, and decreased blood flow. Coldness, numbness, tingling, and pain are signs of peripheral arterial occlusion, and immediate intervention is required.

A community health nurse teaches a group of older adults about modifiable risk factors that contribute to the development of peripheral arterial disease (PAD). The nurse knows that the teaching was effective based on which statement? "I will need to stop smoking because the nicotine causes less blood to flow to my hands and feet." "Because my family is from Italy, I have a higher risk of developing peripheral arterial disease." "The older I get the higher my risk for peripheral arterial disease gets." "I will need to increase the amount of green leafy vegetables I eat to lower my cholesterol levels."

"I will need to stop smoking because the nicotine causes less blood to flow to my hands and feet."

A community health nurse teaches a group of seniors about modifiable risk factors that contribute to the development of peripheral arterial disease (PAD).

"I will need to stop smoking because the nicotine causes less blood to flow to my hands and feet." The use of tobacco products may be one of the most important risk factors in the development of atherosclerotic lesions. Nicotine in tobacco decreases blood flow to the extremities and increases heart rate and blood pressure by stimulating the sympathetic nervous system. This causes vasoconstriction, thereby decreasing arterial blood flow. It also increases the risk of clot formation by increasing the aggregation of platelets.

The nurse is monitoring a patient who is on heparin anticoagulant therapy. What should the nurse determine the therapeutic range of the international normalized ratio (INR) should be? 2.0-3.0 4.0-5.0 7.0-8.0 5.0-6.0

2.0-3.0

A client with peripheral arterial disease asks the nurse about using a heating pad to warm the feet. The nurse's best response is which of the following?

"It is better to put the heating pad on your abdomen, which causes vasodilation and warmth to your feet."

A client with peripheral arterial disease asks the nurse about using a heating pad to warm the feet. The nurse's best response is which of the following? "A heating pad to your feet is a good idea because it increases the metabolic rate." "It is better to put the heating pad on your abdomen, which causes vasodilation and warmth to your feet." "A heating pad to your feet is fine as long as the temperature stays below 105 degrees F." "It is better to soak your feet in hot water as long as the water temperature is below 110 degrees F."

"It is better to put the heating pad on your abdomen, which causes vasodilation and warmth to your feet."

"It is better to put the heating pad on your abdomen, which causes vasodilation and warmth to your feet." It is safer to apply a heating pad to the abdomen, causing a reflex vasodilation in the extremities. Heat may be applied directly to ischemic extremities; however, the temperature of the heating source must not exceed body temperature. Excess heat may increase the metabolic rate of the extremities and increase the need for oxygen beyond that provided by the reduced arterial flow through the diseased artery.

A client complains of leg pain brought on by walking several blocks — a symptom that first arose several weeks earlier. The client's history includes diabetes mellitus and a two-pack-per-day cigarette habit for the past 42 years. The physician diagnoses intermittent claudication and orders pentoxifylline (Trental), 400 mg three times daily with meals. Which instruction concerning long-term care should the nurse provide? a) "See the physician if complications occur." b) "Reduce your level of exercise." c) "Practice meticulous foot care." d) "Consider cutting down on your smoking."

"Practice meticulous foot care." Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing. Therefore, meticulous foot care is essential. The nurse should teach the client to bathe his feet in warm water and dry them thoroughly, cut the toenails straight across, wear well-fitting shoes, and avoid taking medications without the approval of a physician. Because nicotine is a vasoconstrictor, this client should stop smoking, not just consider cutting down. Daily walking is beneficial to clients with intermittent claudication. To evaluate the effectiveness of the therapeutic regimen, this client should see the physician regularly, not just when complications occur.

A nurse is providing education about maintaining tissue integrity to a client with peripheral arterial disease. Which of the following statements by the client indicates a need for clarification? a) "Shoes made of synthetic material are best for my feet." b) "I should apply powder daily because my feet perspire." c) "I can use lamb's wool between my toes if necessary." d) "It is important to apply sunscreen to the top of my feet when wearing sandals."

"Shoes made of synthetic material are best for my feet." The client should wear leather shoes with an extra-depth toebox. Synthetic shoes do not allow air to circulate.

A patient admitted to the medical surgical unit with a venous thromboembolism (VTE) is started on enoxaparin (Lovenox) and warfarin (Coumadin). The patient asks the nurse why two medications are needed. Which response by the nurse is accurate? a) "Lovenox will dissolve the clot, and Coumadin will prevent any more clots from occurring." b) "Administration of two anticoagulants decreases the risk of recurrent venous thrombosis." c) "The Lovenox will work immediately, but the Coumadin takes several days to reach its full effect." d) "Because of the potential for a pulmonary embolism, it is important for you to have at least two anticoagulants."

"The Lovenox will work immediately, but the Coumadin takes several days to reach its full effect." Oral anticoagulants, such as warfarin, are monitored by the prothrombin time (PT) or the international normalized ratio (INR). Because the full anticoagulant effect of warfarin is delayed for 3 to 5 days, it is usually administered concurrently with heparin until desired anticoagulation has been achieved (ie, when the PT is 1.5 to 2 times normal or the INR is 2.0 to 3.0).

The nurse is assisting a patient with peripheral arterial disease to ambulate in the hallway. What should the nurse include in the education of the patient during ambulation? "Walk to the point of pain, rest until the pain subsides, then resume ambulation." "If you feel any discomfort, stop and we will use a wheelchair to take you back to your room." "As soon as you feel pain, we will go back and elevate your legs." "If you feel pain during the walk, keep walking until the end of the hallway is reached."

"Walk to the point of pain, rest until the pain subsides, then resume ambulation."

When caring for a patient who has started anticoagulant therapy with warfarin (Coumadin), the nurse knows that therapeutic benefits will not occur for:

3 to 5 days.

A 56-year-old woman with severe varicose veins has opted for venous ablation, and the nurse is providing patient education before the scheduled procedure. What instructions should the nurse provide to this patient? a) "If you notice any bruising in the area, make sure to let someone know because that could be a sign of a serious complication." b) "You might experience some pain after the procedure, but this will be managed with ice packs rather than medications." c) "We'll help you get walking as soon as you sedation has worn off, and you'll continue to gradually increase your activity level." d) "Try to limit your activity for the first 10 days to 2 weeks to prevent reoccurrence of your varicose veins."

"We'll help you get walking as soon as you sedation has worn off, and you'll continue to gradually increase your activity level."

When administering heparin anticoagulant therapy, the nurse needs to make certain that the activated partial thromboplastin time (aPTT) is within the therapeutic range of: 1.5 to 2.5 times the baseline control. 3.5 times the baseline control. 2.5 to 3.0 times the baseline control. 4.5 times the baseline control.

1.5 to 2.5 times the baseline control.

1.5 to 2.5 times the baseline control. A normal PTT level is 21 to 35 seconds. A reading of more than 100 seconds indicates a significant risk of hemorrhage.

Heparin therapy is usually considered therapeutic when the activated partial thromboplastin time (aPTT) is how many times higher than a normal value? 1 to 1.5 1.5 to 2 2 to 2.5 2.5 to 3

2 to 2.5

The nurse is monitoring a patient who is on heparin anticoagulant therapy. What should the nurse determine the therapeutic range of the international normalized ratio (INR) should be?

2.0-3.0

When caring for a patient who has started anticoagulant therapy with warfarin (Coumadin), the nurse knows that therapeutic benefits will not occur for: a. The first 24 hours. b. 2 to 3 days. c. At least 12 hours. d. 3 to 5 days.

3 to 5 days. It takes 3 to 5 days for a therapeutic international normalized ratio (INR) to be achieved. Therefore, Coumadin is given concurrently with heparin until a therapeutic level is established, usually within 72 hours.

Which of the following diagnostic tests are used to quantify venous reflux and calf muscle pump ejection? a) Contrast phlebography b) Lymphangiography c) Lymphoscintigraphy d) Air plethysmography

Air plethysmography Air plethysmography is used to quantify venous reflux and calf muscle pump action. Contrast phlebography involves injecting a radiopaque contrast agent into the venous system. Lymphoscintigraphy is done when a radioactively labeled colloid is injected subcutaneously in the second interdigital space. The extremity is then exercised to facilitate the uptake of the colloid by the lymphatic system, and serial images are obtained at present intervals. Lymphoangiography provides a way of detecting lymph node involvement resulting from metastatic carcinoma, lymphoma, or infection in sites that are otherwise inaccessible to the examiner except by surgery.

A client is being discharged home with a venous stasis ulcer on the right lower leg. Which topic will the nurse include in client teaching before discharge?

Application of graduated compression stockings

A client is being discharged home with a venous stasis ulcer on the right lower leg. Which topic will the nurse include in client teaching before discharge? a. Adequate carbohydrate intake b. Methods of keeping the wound area dry c. Prophylactic antibiotic therapy d.Application of graduated compression stockings

Application of graduated compression stockings Graduated compression stockings usually are prescribed for clients with venous insufficiency. The required pressure gradient is determined by the amount and severity of venous disease. Graduated compression stockings are designed to apply 100% of the prescribed pressure gradient at the ankle and pressure that decreases as the stocking approaches the thigh, reducing the caliber of the superficial veins in the leg and increasing flow in the deep veins. These stockings may be knee high, thigh high, or pantyhose.

The nurse is assessing a patient two days postoperatively who is suspected of having deep vein obstruction. The patient is complaining of pain in the left lower extremity and there is a 2-cm difference in the right and left leg circumference. What intervention can the nurse provide to promote arterial flow to the lower extremities?

Apply a heating pad to the patient's abdomen.

Vasodilation or vasoconstriction produced by an external cause will interfere with a nurse's accurate assessment of a client with peripheral vascular disease (PVD). Therefore, the nurse should: a) match the room temperature to the client's body temperature. b) maintain room temperature at 78° F (25.6° C). c) keep the client warm. d) keep the client uncovered.

C) keep the client warm. The nurse should keep the client covered and expose only the portion of the client's body that she's assessing. The nurse should also keep the client warm by maintaining his room temperature between 68° F and 74° F (20° and 23.3° C). Extreme temperatures aren't good for clients with PVD. The valves in their arteries and veins are already insufficient, and exposing them to vast changes in temperature could affect assessment findings. Keeping the client uncovered would cause him to become chilled. Matching the room temperature to the client's body temperature is inappropriate.

A client comes to the emergency department (ED) complaining of precordial chest pain. In describing the pain, the client describes it as pressure with a sudden onset. What disease process would you suspect in this client? a) Venous occlusive disease b) Cardiogenic shock c) Coronary artery disease d) Raynaud's disease

Coronary artery disease The classic symptom of CAD is chest pain (angina) or discomfort during activity or stress. Such pain or discomfort typically is manifested as sudden pain or pressure that may be centered over the heart (precordial) or under the sternum (substernal). Raynaud's disease in the hands presents with symptoms of hands that are cold, blanched, and wet with perspiration. Cardiogenic shock is a complication of an MI. Venous occlusive disease occurs in the veins, not the arteries.

A nurse is caring for a patient who experienced an MI. The patient is ordered metoprolol (Lopressor). The nurse understands that the therapeutic effect of this medication is which of the following? a) Increases cardiac output b) Decreases resting heart rate c) Decreases cholesterol level d) Decreases platelet aggregation

Decreases resting heart rate The therapeutic effects of beta-adrenergic blocking agents such as metoprolol are to reduce the myocardial oxygen consumption by blocking beta-adrenergic sympathetic stimulation to the heart. The result is reduced heart rate, slowed conduction of impulses through the conduction system, decreased blood pressure, and reduced myocardial contractility to balance the myocardial oxygen needs and amount of oxygen available. This helps to control chest pain and delays the onset of ischemia during work or exercise. This classification of medication also reduces the incidence of recurrent angina, infarction, and cardiac mortality. Generally the dosage of medication is titrated to achieve a resting heart rate of 50-60 bpm. Metoprolol is not administered to decrease cholesterol levels, increase cardiac output, or decrease platelet aggregation.

The nurse knows which diagnostic test isused to document the anatomic site of reflux and provides a quantitative measure of the severity of valvular reflux?

Duplex ultrasound scan

The nurse knows which of the following diagnostic tests are used to document the anatomic site of reflux and provides a quantitative measure of the severity of valvular reflux? a) Duplex ultrasound scan b) Contrast phlebography c) Lymphoscintigraphy d) Lymphangiography

Duplex ultrasound scan Diagnostic tests for varicose veins include the duplex ultrasound scan, which documents the anatomic site of reflux and provides a quantitative measure of the severity of valvular reflux. Contrast phlebography involves injecting a radiopaque contrast agent into the venous system. Lymphoscintigraphy is done when a radioactively labeled colloid is injected subcutaneously in the second interdigital space. The extremity is then exercised to facilitate the uptake of the colloid by the lymphatic system, and serial images are obtained at present intervals. Lymphoangiography provides a way of detecting lymph node involvement resulting from metastatic carcinoma, lymphoma, or infection in sites that are otherwise inaccessible to the examiner except by surgery.

Inadequate fluid volume Urine output of less than 25 mL per hour may indicate a decrease in cardiac output. A high specific gravity indicates increased concentration of solutes in the urine which occurs with inadequate fluid volume. Indices of normal glomerular filtration are output of 25 mLor greater per hour and specific gravity between 1.010 and 1.025. Overhydration is manifested by high urine output with low specific gravity. The anuric patient does not produce urine.

Which of the following is the most important postoperative assessment parameter for patients undergoing cardiac surgery? a) Blood glucose level b) Activity intolerance c) Inadequate tissue perfusion d) Mental alertness

Inadequate tissue perfusion The nurse must assess the patient for signs and symptoms of inadequate tissue perfusion, such as a weak or absent pulse, cold or cyanotic extremities, or mottling of the skin. Although the nurse does assess blood sugar and mental status, tissue perfusion is the higher priority. Assessing for activity intolerance, while important later in the recovery period, is not essential in the immediate postoperative period for patients undergoing cardiac surgery.

A client is diagnosed with deep vein thrombosis (DVT). Which nursing diagnosis should receive highest priority at this time? Ineffective peripheral tissue perfusion related to venous congestion Excess fluid volume related to peripheral vascular disease Risk for injury related to edema Impaired gas exchange related to increased blood flow

Ineffective peripheral tissue perfusion related to venous congestion

A client is diagnosed with deep vein thrombosis (DVT). Which nursing diagnosis should receive highest priority at this time? a) Excess fluid volume related to peripheral vascular disease b) Risk for injury related to edema c) Ineffective peripheral tissue perfusion related to venous congestion d) Impaired gas exchange related to increased blood flow

Ineffective peripheral tissue perfusion related to venous congestion Ineffective peripheral tissue perfusion related to venous congestion takes highest priority because venous inflammation and clot formation impede blood flow in a client with DVT. Impaired gas exchange related to increased blood flow is incorrect because impaired gas exchange is related to decreased, not increased, blood flow. Excess fluid volume related to peripheral vascular disease is inappropriate because there's no evidence that this client has an excess fluid volume. Risk for injury related to edema may be warranted but is secondary to ineffective tissue perfusion.

What should the nurse do first? a) Decrease the heparin infusion rate. b) Start an I.V. infusion of dextrose 5% in water (D5W). c) Prepare to administer protamine sulfate. d) Monitor the partial thromboplastin time (PTT).

Prepare to administer protamine sulfate. Frank hematuria indicates excessive anticoagulation and bleeding — and heparin overdose. The nurse should discontinue the heparin infusion immediately and prepare to administer protamine sulfate, the antidote for heparin. Decreasing the heparin infusion rate wouldn't prevent further bleeding. Although the nurse should continue to monitor PTT, this action should occur later. An I.V. infusion of D5W may be administered, but only after protamine has been given.

A postoperative client is receiving heparin after developing thrombophlebitis. The nurse monitors the client carefully for bleeding and other adverse effects of heparin.

A physician orders blood coagulation tests to evaluate a client's blood-clotting ability. The nurse knows that such tests are important in assessing clients at risk for thrombi, such as those with a history of atrial fibrillation, infective endocarditis, prosthetic heart valves, or myocardial infarction. Which test determines a client's response to oral anticoagulant drugs? a) Prothrombin time (PT) b) Platelet count c) Partial thromboplastin time (PTT) d) Bleeding time

Prothrombin time (PT) PT determines a client's response to oral anticoagulant therapy. This test measures the time required for a fibrin clot to form in a citrated plasma sample following addition of calcium ions and tissue thromboplastin and compares this time with the fibrin-clotting time in a control sample. The physician should adjust anticoagulant dosages as needed, to maintain PT at 1.5 to 2.5 times the control value. Bleeding time indicates how long it takes for a small puncture wound to stop bleeding. The platelet count reflects the number of circulating platelets in venous or arterial blood. PTT determines the effectiveness of heparin therapy and helps physicians evaluate bleeding tendencies. Physicians diagnose appoximately 99% of bleeding disorders on the basis of PT and PTT values.

The nurse is caring for a client with abdominal aortic aneurysm (AAA). Which assessment finding is most likely to indicate a dissection of the aneurysm? Hematemesis Hypertensive crisis Rectal bleeding Severe back pain

Severe back pain

During his annual physical exam, a 62-year-old male client reports experiencing chest pain and palpitations during and after his morning jogs. Family history reveals coronary artery disease. The nurse should instruct the client in the following to reduce the client's cardiac risk? a) Smoking cessation b) Antioxidant supplements c) Exercise avoidance d) Protein-rich diet

Smoking cessation The first line of defense for clients with CAD is lifestyle changes including smoking cessation, weight loss, stress management, and exercise. Clients with CAD should eat a balanced diet. Clients with CAD should exercise, as tolerated, to maintain a healthy weight. Antioxidant supplements, such as those containing vitamin E, beta carotene, and selenium, are not recommended because clinical trials have failed to confirm beneficial effects from their use.

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions? a) Decreasing blood pressure and increasing mobility b) Stabilizing heart rate and blood pressure and easing anxiety c) Increasing blood pressure and reducing mobility d) Increasing blood pressure and monitoring fluid intake and output

Stabilizing heart rate and blood pressure and easing anxiety For a client with an aneurysm, nursing interventions focus on preventing aneurysm rupture by stabilizing heart rate and blood pressure. Easing anxiety also is important because anxiety and increased stimulation may raise the heart rate and boost blood pressure, precipitating aneurysm rupture. The client with an abdominal aortic aneurysm is typically hypertensive, so the nurse should take measures to lower blood pressure, such as administering antihypertensive agents, as ordered, to prevent aneurysm rupture. To sustain major organ perfusion, the client should maintain a mean arterial pressure of at least 60 mm Hg. Although the nurse must assess each client's mobility individually, most clients need bed rest when initially attempting to gain stability

A nurse is providing education about the prevention of arterial constriction to a client with peripheral arterial disease. Which of the following includes priority information the nurse would give to the client? a) Stop smoking. b) Wear antiembolytic stockings daily to assist with blood return to the heart. c) Do not cross your legs for more than 30 minutes at a time. d) Keep your feet elevated above your heart.

Stop smoking. Nicotine from tobacco products causes vasospasm and can thereby dramatically reduce circulation to the extremities. When the client elevates the feet above the heart level, the heart must work against gravity to supply blood to the feet. Antiembolytic stocking are helpful for venous return to the heart, but constriction is not helpful for lack of arterial blood flow. Crossing the legs for more than a few minutes at a time compresses arteries and decreases blood supply to the legs and feet.

Taking daily walks Taking daily walks relieves symptoms of intermittent claudication, although the exact mechanism is unclear. Anaerobic exercise may make these symptoms worse. Clients with chronic arterial occlusive disease must reduce daily fat intake to 30% or less of total calories. The client should limit dietary cholesterol because hyperlipidemia is associated with atherosclerosis, a known cause of arterial occlusive disease. However, HDLs have the lowest cholesterol concentration, so this client should eat, not abstain from, foods that raise HDL levels.

A client with venous insufficiency develops varicose veins in both legs. Which statement about varicose veins is accurate?

The severity of discomfort isn't related to the size of varicosities.

A client with venous insufficiency develops varicose veins in both legs. Which statement about varicose veins is accurate? The severity of discomfort isn't related to the size of varicosities. Sclerotherapy is used to cure varicose veins. Varicose veins are more common in men than in women. Primary varicose veins are caused by deep vein thrombosis (DVT) and inflammation.

The severity of discomfort isn't related to the size of varicosities.

The nurse teaches the patient with peripheral vascular disease (PVD) to refrain from smoking because nicotine causes a) a slowed heart rate. b) diuresis. c) depression of the cough reflex. d) a vasospasm.

a vasospasm. Nicotine causes vasospasm and can thereby dramatically reduce circulation to the extremities. Nicotine has stimulant effects. Nicotine does not suppress cough. Smoking irritates the bronchial tree, causing coughing. Nicotine does not cause diuresis.

The severity of discomfort isn't related to the size of varicosities. Clients with varicose veins commonly complain of aching, heaviness, itching, moderate swelling, and unsightly appearance of the legs. However, the severity of discomfort is hard to assess and seems unrelated to the size of varicosities. Varicose veins are more common in women than in men. Primary varicose veins typically result from a congenital or familial predisposition that makes the vein wall less elastic; secondary varicosities occur when trauma, obstruction, DVT, or inflammation damages valves. Sclerotherapy, in which a sclerosing agent is injected into a vein, is used to treat varicose veins; it doesn't cure them.

The most important factor regulating the caliber of blood vessels, which determines resistance to flow, is: Hormonal secretion. Independent arterial wall activity. The influence of circulating chemicals. The sympathetic nervous system.

When the patient diagnosed with angina pectoris complains that he is experiencing chest pain more frequently even at rest, the period of pain is longer, and it takes less stress for the pain to occur, the nurse recognizes that the patient is describing which type of angina? a) Refractory b) Intractable c) Variant d) Unstable

Unstable Unstable angina is also called crescendo or preinfarction angina and indicates the need for a change in treatment. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment. Variant angina is described as pain at rest with reversible ST-segment elevation and is thought to be caused by coronary artery vasospasm. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment.

The nurse teaches the patient with peripheral vascular disease (PVD) to refrain from smoking because nicotine causes which of the following? a) Slowed heart rate b) Vasospasm c) Diuresis d) Depression of the cough reflex

Vasospasm Nicotine causes vasospasm and can thereby dramatically reduce circulation to the extremities. Tobacco smoke also impairs transport and cellular use of oxygen and increases blood viscosity. Patients with arterial insufficiency who smoke or chew tobacco must be fully informed of the effects of nicotine on circulation and be encouraged to stop.

The nurse is caring for a client who is scheduled to have a vein ligation in the morning. How would you describe a vein ligation to the client? Removal of the small saphenous vein. Removal of the great saphenous vein. Veins are tied off and removed. Veins are tied off and left in the leg.

Veins are tied off and left in the leg.

What is the most important factor in regulating the caliber of blood vessels, which determines resistance to flow?

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

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

The nurse teaches the patient with peripheral vascular disease (PVD) to refrain from smoking because nicotine causes a) depression of the cough reflex. b) diuresis. c) a vasospasm. d) a slowed heart rate.

a vasospasm. Nicotine causes vasospasm and can thereby dramatically reduce circulation to the extremities. Nicotine has stimulant effects. Nicotine does not suppress cough. Smoking irritates the bronchial tree, causing coughing. Nicotine does not cause diuresis.

The term for a diagnostic test that involves injection of a contrast media into the venous system through a dorsal vein in the foot is a) a lymphoscintigraphy. b) a contrast phlebography. c) an air plethysmography. d) a lymphangiography.

a contrast phlebography. When a thrombus exists, an x-ray image will disclose an unfilled segment of a vein. Air plethysmography quantifies venous reflux and calf muscle pump ejection. In lymphangiography, contrast media are injected into the lymph system. In a lymphoscintigraphy, a radioactive-labeled colloid is injected into the lymph system.

A nurse is reviewing self-care measures for a client with peripheral vascular disease. Which statement indicates proper self-care measures? a) "I have my wife look at the soles of my feet each day." b) "I like to soak my feet in the hot tub every day." c) "I stopped smoking and use only chewing tobacco." d) "I walk only to the mailbox in my bare feet."

a) "I have my wife look at the soles of my feet each day." A client with peripheral vascular disease should examine his feet daily for redness, dryness, or cuts. If a client isn't able to do this examination on his own, then a caregiver or family member should help him. A client with peripheral vascular disease should avoid hot tubs because decreased sensation in the feet may make him unable to tell if the water is too hot. The client should always wear shoes or slippers on his feet when he is out of bed to help minimize trauma to the feet. Any type of nicotine, whether it's from cigarettes or smokeless tobacco, can cause vasoconstriction and further decrease blood supply to the extremities.

Beginning warfarin concomitantly with heparin can provide a stable INR by which day of heparin treatment? a) 5 b) 2 c) 3 d) 4

a) 5 Beginning warfarin concomitantly with heparin can provide a stable INR by day 5 of heparin treatment, at which time the heparin maybe discontinued.

A nurse is caring for a client who is exhibiting signs and symptoms characteristic of a myocardial infarction (MI). Which statement describes priorities the nurse should establish while performing the physical assessment? a) Assess the client's level of pain and administer prescribed analgesics. b) Ensure that the client's family is kept informed of his status. c) Prepare the client for pulmonary artery catheterization. d) Assess the client's level of anxiety and provide emotional support.

a) Assess the client's level of pain and administer prescribed analgesics. The cardinal symptom of MI is persistent, crushing substernal pain or pressure. The nurse should first assess the client's pain and prepare to administer nitroglycerin or morphine for pain control. The client must be medically stabilized before pulmonary artery catheterization can be used as a diagnostic procedure. Anxiety and a feeling of impending doom are characteristic of MI, but the priority is to stabilize the client medically. Although the client and his family should be kept informed at every step of the recovery process, this action isn't the priority when treating a client with a suspected MI.

The most common site of aneurysm formation is in the: a) aortic arch, around the ascending and descending aorta. b) abdominal aorta, just below the renal arteries. c) ascending aorta, around the aortic arch. d) descending aorta, beyond the subclavian arteries.

abdominal aorta, just below the renal arteries. About 75% of aneurysms occur in the abdominal aorta, just below the renal arteries (Debakey type I aneurysms). Debakey type II aneurysms occur in the aortic arch around the ascending and descending aorta, whereas Debakey type III aneurysms occur in the descending aorta, beyond the subclavian arteries.

When caring for a client with a diagnosis of aortic aneurysm scheduled for surgery, what would be most important for the nurse to monitor? a) Level of consciousness, characteristics of pain, and signs of hemorrhage or dissection b) Intake and output, nutrition level, respirations, and characteristics of pain c) Cultural needs, characteristics of pain, and signs of hemorrhage or dissection d) BP, pulse, respirations, and signs of hemorrhage or dissection

a) Level of consciousness, characteristics of pain, and signs of hemorrhage or dissection The nurse monitors BP, pulse, hourly urine output, skin color, level of consciousness, and characteristics of pain for signs of hemorrhage or dissection. Assessing respirations, nutritional levels, and cultural needs are important but not the most important assessments for the nurse to make.

A client has been diagnosed with peripheral arterial occlusive disease. Which of the following instructions is appropriate for the nurse to give the client for promoting circulation to the extremities? a) Participate in a regular walking program. b) Massage the calf muscles if pain occurs. c) Use a heating pad to promote warmth. d) Keep the extremities elevated slightly.

a) Participate in a regular walking program. Clients diagnosed with peripheral arterial occlusive disease should be encouraged to participate in a regular walking program to help develop collateral circulation. They should be advised to rest if pain develops and to resume activity when pain subsides. Extremities should be kept in a dependent position to promote circulation; elevation of the extremities will decrease circulation. Heating pads should not be used by anyone with impaired circulation to avoid burns. Massaging the calf muscles will not decrease pain. Intermittent claudication subsides with rest.

Which of the following is accurate regarding the effects of nicotine and tobacco smoke on the body? Select all that apply. a) Reduces circulation to the extremities b) Impairs transport and cellular use of oxygen c) Causes vasospasm d) Increases blood viscosity e) Decreases blood viscosity

a) Reduces circulation to the extremities b) Impairs transport and cellular use of oxygen c) Causes vasospasm d) Increases blood viscosity Nicotine from tobacco products causes vasospasm and can dramatically reduce circulation to the extremities. Tobacco smoke also impairs transport and cellular use of oxygen and increases blood viscosity.

A nurse should be prepared to manage complications following abdominal aortic aneurysm resection. Which complication is most common? a) Renal failure b) Graft occlusion c) Hemorrhage and shock d) Enteric fistula

a) Renal failure Renal failure commonly occurs if clamping time is prolonged, cutting off the blood supply to the kidneys. Hemorrhage and shock are the most common complications before abdominal aortic aneurysm resection, and they occur if the aneurysm leaks or ruptures. Graft occlusion and enteric fistula formation are rare complications of abdominal aortic aneurysm repair.

A client has a blockage in the proximal portion of a coronary artery. After learning about treatment options, the client decides to undergo percutaneous transluminal coronary angioplasty (PTCA). During this procedure, the nurse expects to administer an: a) anticonvulsant. b) antihypertensive. c) anticoagulant. d) antibiotic.

a) anticoagulant. During PTCA, the client receives heparin, an anticoagulant, as well as calcium agonists, nitrates, or both, to reduce coronary artery spasm. Nurses don't routinely give antibiotics during this procedure; however, because the procedure is invasive, the client may receive prophylactic antibiotics to reduce the risk of infection. An antihypertensive may cause hypotension, which should be avoided during the procedure. An anticonvulsant isn't indicated because this procedure doesn't increase the risk of seizures.

To check for arterial insufficiency when a client is in a supine position, the nurse should elevate the extremity at a 45-degree angle and then have the client sit up. The nurse suspects arterial insufficiency if the assessment reveals: a) dependent pallor. b) elevational rubor. c) a 30-second filling time for the veins. d) no rubor for 10 seconds after the maneuver.

a) dependent pallor. If arterial insufficiency is present, elevation of the limb would yield a pallor from the lack of circulation. Rubor and increased venous filling time would suggest venous problems secondary to venous trapping and incompetent valves.

When caring for a client with a diagnosis of aortic aneurysm scheduled for surgery, what would be most important for the nurse to monitor? a) Level of consciousness, characteristics of pain, and signs of hemorrhage or dissection b) BP, pulse, respirations, and signs of hemorrhage or dissection c) Cultural needs, characteristics of pain, and signs of hemorrhage or dissection d) Intake and output, nutrition level, respirations, and characteristics of pain

a)Level of consciousness, characteristics of pain, and signs of hemorrhage or dissection The nurse monitors BP, pulse, hourly urine output, skin color, level of consciousness, and characteristics of pain for signs of hemorrhage or dissection. Assessing respirations, nutritional levels, and cultural needs are important but not the most important assessments for the nurse to make.

A client complains of leg pain brought on by walking several blocks — a symptom that first arose several weeks earlier. The client's history includes diabetes mellitus and a two-pack-per-day cigarette habit for the past 42 years. The physician diagnoses intermittent claudication and orders pentoxifylline (Trental), 400 mg three times daily with meals. Which instruction concerning long-term care should the nurse provide? a) "See the physician if complications occur." b) "Practice meticulous foot care." c) "Consider cutting down on your smoking." d) "Reduce your level of exercise."

b) "Practice meticulous foot care." Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing. Therefore, meticulous foot care is essential. The nurse should teach the client to bathe his feet in warm water and dry them thoroughly, cut the toenails straight across, wear well-fitting shoes, and avoid taking medications without the approval of a physician. Because nicotine is a vasoconstrictor, this client should stop smoking, not just consider cutting down. Daily walking is beneficial to clients with intermittent claudication. To evaluate the effectiveness of the therapeutic regimen, this client should see the physician regularly, not just when complications occur.

Which of the following diagnostic tests are used to quantify venous reflux and calf muscle pump ejection? a) Lymphangiography b) Air plethysmography c) Lymphoscintigraphy d) Contrast phlebography

b) Air plethysmography Air plethysmography is used to quantify venous reflux and calf muscle pump action. Contrast phlebography involves injecting a radiopaque contrast agent into the venous system. Lymphoscintigraphy is done when a radioactively labeled colloid is injected subcutaneously in the second interdigital space. The extremity is then exercised to facilitate the uptake of the colloid by the lymphatic system, and serial images are obtained at present intervals. Lymphoangiography provides a way of detecting lymph node involvement resulting from metastatic carcinoma, lymphoma, or infection in sites that are otherwise inaccessible to the examiner except by surgery.

A client is hospitalized for repair of an abdominal aortic aneurysm. The nurse must be alert for signs and symptoms of aneurysm rupture and thus looks for which of the following? a) Slow heart rate and high blood pressure b) Constant, intense back pain and falling blood pressure c) Constant, intense headache and falling blood pressure d) Higher than normal blood pressure and falling hematocrit

b) Constant, intense back pain and falling blood pressure Indications of a rupturing abdominal aortic aneurysm include constant, intense back pain; falling blood pressure; and decreasing hematocrit.

A home health nurse is teaching a client with peripheral arterial disease ways to improve circulation to the lower extremities. The nurse encourages which of the following in teaching? a) Elevation of the legs above the heart b) Keeping the legs in a neutral or dependent position c) Application of ace wraps from the toe to below the knees d) Use of antiembolytic stockings

b) Keeping the legs in a neutral or dependent position Keeping the legs in a neutral or dependent position assists in delivery of arterial blood from the heart to the lower extremities. All the other choices will aid in venous return, but will hinder arterial supply to the lower extremities.

Postpericardiotomy syndrome may occur in patients who undergo cardiac surgery. The nurse should be alert to which of the following clinical manifestations associated with this syndrome? a) Decreased white blood cell (WBC) count b) Pericardial friction rub c) Decreased erythrocyte sedimentation rate (ESR) d) Hypothermia

b) Pericardial friction rub The syndrome is characterized by fever, pericardial pain, pleural pain, dyspnea, pericardial effusion, pericardial friction rub, and arthralgia. Leukocytosis (elevated WBCs) occurs, along with elevation of the ESR.

The patient has had biomarkers drawn after complaining of chest pain. Which diagnostic of myocardial infarction remains elevated for as long as 3 weeks? a) Total CK b) Myoglobin c) Troponin d) CK-MB

b) Troponin Troponin remains elevated for a long period, often as long as 3 weeks, and it therefore can be used to detect recent myocardial damage. Myoglobin returns to normal in 12 hours. Total CK returns to normal in 3 days. CK-MB returns to normal in 3 to 4 days

Two days after undergoing a total abdominal hysterectomy, a client complains of left calf pain. Venography reveals deep vein thrombosis (DVT). When assessing this client, the nurse is likely to detect: a) loss of hair on the lower portion of the left leg. b) left calf circumference 1" (2.5 cm) larger than the right. c) pallor and coolness of the left foot. d) a decrease in the left pedal pulse.

b) left calf circumference 1" (2.5 cm) larger than the right. Signs of DVT include inflammation and edema in the affected extremity, causing its circumference to exceed that of the opposite extremity. Pallor, coolness, decreased pulse, and hair loss in an extremity signal interrupted arterial blood flow, which doesn't occur in DVT.

In a patient with a bypass graft, the distal outflow vessel must be at least what percentage patent for the graft to remain patent? a) 40 b) 30 c) 50 d) 20

c) 50 The distal outflow vessel must be at least 50% patent for the graft to remain patent.

When teaching a client with peripheral vascular disease about foot care, a nurse should include which instruction? a) Avoid using cornstarch on the feet. b) Avoid using a nail clipper to cut toenails. c) Avoid wearing canvas shoes. d) Avoid wearing cotton socks.

c) Avoid wearing canvas shoes. The client should be instructed to avoid wearing canvas shoes. Canvas shoes cause the feet to perspire, and perspiration can cause skin irritation and breakdown. Cotton and cornstarch absorb perspiration. The client should be instructed to cut toenails straight across with nail clippers.

Which sign or symptom suggests that a client's abdominal aortic aneurysm is extending? a) Elevated blood pressure and rapid respirations b) Decreased pulse rate and blood pressure c) Increased abdominal and back pain d) Retrosternal back pain radiating to the left arm

c) Increased abdominal and back pain Pain in the abdomen and back signify that the aneurysm is pressing downward on the lumbar nerve root and is causing more pain. The pulse rate would increase with aneurysm extension. Chest pain radiating down the arm would indicate myocardial infarction. Blood pressure would decrease with aneurysm extension, and the respiratory rate may not be affected.

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions? a) Increasing blood pressure and monitoring fluid intake and output b) Decreasing blood pressure and increasing mobility c) Stabilizing heart rate and blood pressure and easing anxiety d) Increasing blood pressure and reducing mobility

c) Stabilizing heart rate and blood pressure and easing anxiety For a client with an aneurysm, nursing interventions focus on preventing aneurysm rupture by stabilizing heart rate and blood pressure. Easing anxiety also is important because anxiety and increased stimulation may raise the heart rate and boost blood pressure, precipitating aneurysm rupture. The client with an abdominal aortic aneurysm is typically hypertensive, so the nurse should take measures to lower blood pressure, such as administering antihypertensive agents, as ordered, to prevent aneurysm rupture. To sustain major organ perfusion, the client should maintain a mean arterial pressure of at least 60 mm Hg. Although the nurse must assess each client's mobility individually, most clients need bed rest when initially attempting to gain stability.

Which of the following is the most common site for a dissecting aneurysm? a) Cervical area b) Sacral area c) Thoracic area d) Lumbar area

c) Thoracic area The thoracic area is the most common site for a dissecting aneurysm. About one-third of patients with thoracic aneurysms die of rupture of the aneurysm.

A client with no known history of peripheral vascular disease comes to the emergency department complaining of sudden onset of lower leg pain. Inspection and palpation reveal absent pulses; paresthesia; and a mottled, cyanotic, cold, and cadaverous left calf. While the physician determines the appropriate therapy, the nurse should: a) elevate the affected leg as high as possible. b) place a heating pad around the affected calf. c) keep the affected leg level or slightly dependent. d) shave the affected leg in anticipation of surgery.

c) keep the affected leg level or slightly dependent. While the physician makes treatment decisions, the nurse should maintain the client on bed rest, keeping the affected leg level or slightly dependent (to aid circulation) and protecting it from pressure and other trauma. Warming the leg with a heating pad (or chilling it with an ice pack) would further compromise tissue perfusion and increase injury to the leg. Elevating the leg would worsen tissue ischemia. Shaving an ischemic leg could cause accidental trauma from cuts or nicks.

The nurse teaches the client with peripheral vascular disease (PVD) to refrain from smoking because nicotine

Which of the following medications is considered a thrombolytic? a) Heparin b) Lovenox c) Coumadin d) Alteplase

d) Alteplase Alteplase is considered a thrombolytic, which lyses and dissolves thrombi. Thrombolytic therapy is most effective when given within the first 3 days after acute thrombosis. Heparin, Coumadin, and Lovenox do not lyse clots.

Which of the following is the hallmark symptom for peripheral arterial disease (PAD) in the lower extremity? a) Vertigo b) Dizziness c) Acute limb ischemia d) Intermittent claudication

d) Intermittent claudication The hallmark symptom of PAD in the lower extremity is intermittent claudication. This pain may be described as aching or cramping in a muscle that occurs with the same degree of exercise or activity and is relieved with rest. Acute limb ischemia is a sudden decrease in limb perfusion, which produces new or worsening symptoms that may threaten limb viability. Dizziness and vertigo are associated with upper extremity arterial occlusive disease.

A female client is readmitted to the facility with a warm, tender, reddened area on her right calf. Which contributing factor should the nurse recognize as most important? a) An active daily walking program b) A history of diabetes mellitus c) History of increased aspirin use d) Recent pelvic surgery

d) Recent pelvic surgery The client shows signs of deep vein thrombosis (DVT). The pelvic area has a rich blood supply, and thrombophlebitis of the deep veins is associated with pelvic surgery. Aspirin, an antiplatelet agent, and an active walking program help decrease the client's risk of DVT. In general, diabetes mellitus is a contributing factor associated with peripheral vascular disease.

When the patient diagnosed with angina pectoris complains that he is experiencing chest pain more frequently even at rest, the period of pain is longer, and it takes less stress for the pain to occur, the nurse recognizes that the patient is describing which type of angina? a) Variant b) Refractory c) Intractable d) Unstable

d) Unstable Unstable angina is also called crescendo or preinfarction angina and indicates the need for a change in treatment. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment. Variant angina is described as pain at rest with reversible ST-segment elevation and is thought to be caused by coronary artery vasospasm. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment.

A home health nurse is seeing an elderly male client for the first time. During the physical assessment of the skin on the lower legs, the nurse notes edema, brown pigmentation in the gater area, pedal pulses, and a few irregularly shaped ulcers around the ankles. From these findings, the nurse knows that the client has a problem with peripheral circulation. Which of the following does the nurse suspect? a) Trauma b) Arterial insufficiency c) Neither venous nor arterial insufficiency d) Venous insufficiency

d) Venous insufficiency Symptoms of venous insufficiency include present pedal pulses, edema, pigmentation in gater area, and a reddish blue color. Ulcers caused by venous insufficiency will be irregular in shape and usually located around the ankles or the anterior tibial area. Characteristics of arterial insufficiency ulcers include location at the tips of the toes, great pain, and circular shape with a pale to black ulcer base.

A client with no known history of peripheral vascular disease comes to the emergency department complaining of sudden onset of lower leg pain. Inspection and palpation reveal absent pulses; paresthesia; and a mottled, cyanotic, cold, and cadaverous left calf. While the physician determines the appropriate therapy, the nurse should: a) place a heating pad around the affected calf. b) elevate the affected leg as high as possible. c) shave the affected leg in anticipation of surgery. d) keep the affected leg level or slightly dependent.

d) keep the affected leg level or slightly dependent. While the physician makes treatment decisions, the nurse should maintain the client on bed rest, keeping the affected leg level or slightly dependent (to aid circulation) and protecting it from pressure and other trauma. Warming the leg with a heating pad (or chilling it with an ice pack) would further compromise tissue perfusion and increase injury to the leg. Elevating the leg would worsen tissue ischemia. Shaving an ischemic leg could cause accidental trauma from cuts or nicks.

The most important reason for a nurse to encourage a client with peripheral vascular disease to initiate a walking program is that this form of exercise: a) decreases venous congestion. b) increases high-density lipoprotein (HDL) level. c) aids in weight reduction. d) reduces stress.

decreases venous congestion. Regular walking is the best way to decrease venous congestion because using the leg muscles as a pump helps return blood to the heart. Regular exercise also aids in stress reduction and weight reduction and increases the formation of HDLs — which are all beneficial to a client with peripheral vascular disease. However, these changes don't have as significant an effect on the client's condition as decreasing venous congestion.

To check for arterial insufficiency when a client is in a supine position, the nurse should elevate the extremity at a 45-degree angle and then have the client sit up. The nurse suspects arterial insufficiency if the assessment reveals: a 30-second filling time for the veins. dependent pallor. no rubor for 10 seconds after the maneuver. elevational rubor.

dependent pallor. If arterial insufficiency is present, elevation of the limb would yield a pallor from the lack of circulation. Rubor and increased venous filling time would suggest venous problems secondary to venous trapping and incompetent valves.

forcing blood into the deep venous system. Antiembolism stockings prevent DVT by forcing blood into the deep venous system, instead of allowing blood to pool. Ambulation prevents blood from pooling and prevents DVT, but encouraging ambulation isn't a function of the stockings. Antiembolism stockings could possibly provide warmth, but this factor isn't how they prevent DVT. Elevating the extremity decreases edema but doesn't prevent DVT.

Vasodilation or vasoconstriction produced by an external cause will interfere with a nurse's accurate assessment of a client with peripheral vascular disease (PVD). Therefore, the nurse should: keep the client uncovered. match the room temperature to the client's body temperature. keep the client warm. maintain room temperature at 78° F (25.6° C).

keep the client warm. The nurse should keep the client covered and expose only the portion of the client's body that she's assessing. The nurse should also keep the client warm by maintaining his room temperature between 68° F and 74° F (20° and 23.3° C). Extreme temperatures aren't good for clients with PVD. The valves in their arteries and veins are already insufficient, and exposing them to vast changes in temperature could affect assessment findings. Keeping the client uncovered would cause him to become chilled. Matching the room temperature to the client's body temperature is inappropriate.
