HA Chpt 21 Peripheral Vascular & Lymph System Practice Questions

5. The nurse is reviewing venous blood flow patterns. Which of these statements best describes the mechanism(s) by which venous blood returns to the heart? a. Intraluminal valves ensure unidirectional flow toward the heart. b. Contracting skeletal muscles milk blood distally toward the veins. c. High-pressure system of the heart helps facilitate venous return. d. Increased thoracic pressure and decreased abdominal pressure facilitate venous return to the heart.

ANS: A Blood moves through the veins by (1) contracting skeletal muscles that milk the blood proximally back toward the heart; (2) pressure gradients caused by breathing, during which inspiration makes the thoracic pressure decrease and the abdominal pressure increase; and (3) the intraluminal valves, which ensure unidirectional flow toward the heart.

8. The nurse is reviewing the risk factors for venous disease. Which of these situations best describes a person at highest risk for the development of venous disease? a. Person who has been on bed rest for 4 days b. Older adult taking anticoagulant medication c. Woman in the second month of her first pregnancy d. Person with a 30-year, 1 pack per day smoking habit

ANS: A Efficient venous return depends on contracting skeletal muscles, competent valves in the veins, and a patent lumen. Problems with any of these three elements lead to venous stasis. People who undergo prolonged standing, sitting, or bed rest are at risk for venous disease because they do not benefit from the milking action to the veins that walking accomplishes. Hypercoagulable (not anticoagulated) states and vein wall trauma also place the person at risk for venous disease. Obesity and multiple pregnancies are also risk factors. Smoking is a risk factor for arterial disease, not venous disease

24. How should the nurse document mild, slight pitting edema the ankles of a pregnant patient? a. 1+/0-4+ b. 3+/0-4+ c. 4+/0-4+ d. Brawny edema

ANS: A If pitting edema is present, then the nurse should grade it on a scale of 1+ (mild) to 4+ (severe). Brawny edema appears as nonpitting edema and feels hard to the touch.

14. A 67-year-old patient states that he recently began to have pain in his left calf when climbing the 10 stairs to his apartment. This pain is relieved by sitting for "a couple of minutes"; then he is able to resume his activities. What do these symptoms suggest? a. Claudication b. Sore muscles c. Muscle cramps d. Venous insufficiency

ANS: A Intermittent claudication feels like a cramp and is usually relieved by rest within 2 minutes. The other responses are not correct. Sore muscles and muscle cramps do not usually occur while performing an activity, but afterwards, and are not relieved by resting for a couple of minutes. Venous insufficiency does not cause pain with walking or exercise that is relieved by rest, but rather presents with edema, thickened skin, and brown discoloration in lower legs. The symptoms this patient described suggest intermittent claudication.

12. The nurse is examining the lymphatic system of a healthy 3-year-old child. Which finding should the nurse expect? a. Palpable superficial lymph nodes b. Excessive swelling of the lymph nodes c. No palpable nodes because of the immature immune system of a child d. Fewer and smaller sized lymph nodes compared with those of an adult

ANS: A Lymph nodes are relatively large in children, and the superficial ones are often palpable even when the child is healthy.

29. During an assessment, the nurse notices that a patient's left arm is swollen from the shoulder down to the fingers, with nonpitting brawny edema. The right arm is normal. The patient had a left-sided mastectomy 1 year ago. Based on these findings, what does the nurse suspect? a. Lymphedema b. Venous stasis c. Arteriosclerosis d. Deep-vein thrombosis

ANS: A Lymphedema after breast cancer causes unilateral swelling and nonpitting brawny edema, with overlying skin indurated. It is caused by the removal of lymph nodes with breast surgery or damage to lymph nodes and channels with radiation therapy for breast cancer, and lymphedema can impede drainage of lymph. The other responses are not correct. Venous stasis is the pooling of blood in the legs, not in the arms. Deep vein thrombosis is the development of a thrombus, or clot, in a deep vein, most commonly in the legs, not the arms. Arteriosclerosis is increased rigidity of the peripheral blood vessels that occurs with aging. The symptoms this patient is experiencing are from lymphedema.

37. A patient is recovering from several hours of orthopedic surgery. During an assessment of the patient's lower legs, the nurse will monitor for signs of acute venous symptoms. Signs of acute venous symptoms include which of the following? (Select all that apply.) a. Sudden onset b. Warm, red, and swollen calf c. Pain that is worse at the end of the day d. Aching, tired pain, with a feeling of fullness e. Pain that is relieved with elevation of the leg. f. Intense, sharp pain, with the deep muscle tender to the touch

ANS: A, B, F Signs and symptoms of acute venous problems include pain in the calf that has a sudden onset and that is intense and sharp with tenderness in the deep muscle when touched. The calf is warm, red, and swollen. The other options are symptoms of chronic venous problems.

38. A patient has been admitted with chronic arterial symptoms. During the assessment, the nurse should expect which findings? (Select all that apply.) a. Skin of the patient is pale and cool. b. His ankles have two small, weeping ulcers. c. He states that the pain gets worse when walking. d. Patient works long hours sitting at a computer desk. e. Patient has a history of diabetes and cigarette smoking. f. Patient states that the pain is worse at the end of the day.

ANS: A, C, E Patients with chronic arterial symptoms often have a history of smoking and diabetes (among other risk factors). The pain has a gradual onset with exertion and is relieved with rest or dangling. The skin appears cool and pale. The other responses reflect chronic venous problems. Weeping ulcers on ankles, a job involving sitting for long periods of time, and pain that is worse at the end of the day are associated with venous ulcers, not arterial ulcers.

27. During an assessment, the nurse elevated a patient's legs 12 inches off the table and had him wag his feet to drain off venous blood. After helping him sit up and dangle his legs over the side of the table, what should the nurse expect for a normal finding? a. Significant elevational pallor b. Venous filling within 15 seconds c. No change in the coloration of the skin d. Color returning to the feet within 20 seconds of assuming a sitting position

ANS: B In this test, it normally takes 10 seconds or less for the color to return to the feet and 15 seconds for the veins of the feet to fill. Significant elevational pallor, as well as delayed venous filling, occurs with arterial insufficiency.

28. During a visit to the clinic, a woman in her seventh month of pregnancy states that her legs feel "heavy in the calf" and that she often has foot cramps at night. The nurse notices that the patient has dilated, tortuous veins apparent in her lower legs. Which condition is reflected by these findings? a. Lymphedema b. Varicose veins c. Raynaud phenomenon d. Deep vein thrombophlebitis

ANS: B Superficial varicose veins are caused by incompetent distant valves in the veins, which results in the reflux of blood, producing dilated, tortuous veins. Varicose veins are more common in women, and pregnancy can also be a cause. Symptoms include aching, heaviness in the calf, easy fatigability, and night leg or foot cramps. Dilated, tortuous veins are observed on assessment. Lymphedema is the accumulation of protein-rich fluid in the interstitial spaces in the arm, not the leg. Raynaud phenomenon presents as episodes of abrupt, progressive tricolor change of the fingers in response to cold, vibration, or stress. The symptoms of deep vein thrombophlebitis are warmth, swelling, redness, tender to palpation, and may have dependent cyanosis. This patient is experiencing superficial varicose veins which are caused by incompetent distant valves in the veins, which results in the reflux of blood, producing dilated, tortuous veins.

34. During an assessment, a patient tells the nurse that her fingers often change color when she goes out in cold weather. She describes these episodes as her fingers first turning white, then blue, then red with a burning, throbbing pain. What does the nurse suspect? a. Lymphedema b. Raynaud phenomenon c. Deep-vein thrombosis d. Chronic arterial insufficiency

ANS: B The condition with episodes of abrupt, progressive tricolor changes of the fingers in response to cold, vibration, or stress is known as Raynaud phenomenon. Lymphedema is an accumulation of protein-rich fluid in the interstitial spaces in the arm that may occur with breast cancer. Lymphedema after breast cancer causes unilateral swelling and nonpitting brawny edema, with overlying skin indurated. It is caused by the removal of lymph nodes with breast surgery or damage to lymph nodes and channels with radiation therapy for breast cancer. Lymphedema can impede drainage of lymph. Deep vein thrombosis is the development of a thrombus, or clot, in a deep vein, most commonly in the legs, not the arms. Symptoms of chronic arterial insufficiency are significant elevational pallor and delayed venous filling in the legs.

9. The nurse is teaching a review class on the lymphatic system. Which statement by a class participant indicates correct understanding of the material? a. "Lymph flow is propelled by the contraction of the heart." b. "The flow of lymph is slow, compared with that of the blood." c. "One of the functions of the lymph is to absorb lipids from the biliary tract." d. "Lymph vessels have no valves; therefore, lymph fluid flows freely from the tissue spaces into the bloodstream."

ANS: B The flow of lymph is slow, compared with flow of the blood. Lymph flow is not propelled by the heart but rather by contracting skeletal muscles, pressure changes secondary to breathing, and contraction of the vessel walls. Lymph does not absorb lipids from the biliary tract. The vessels do have valves; therefore, flow is one way from the tissue spaces to the bloodstream.

11. A 35-year-old man is seen in the clinic for an infection in his left foot. Which of these findings should the nurse expect to see during an assessment of this patient? a. Hard and fixed cervical nodes b. Enlarged and tender inguinal nodes c. Bilateral enlargement of the popliteal nodes d. Pelletlike nodes in the supraclavicular region

ANS: B The inguinal nodes in the groin drain most of the lymph of the lower extremities. With local inflammation, the nodes in that area become swollen and tender. Since it is the inguinal nodes that drain the lymph from the lower extremities, the cervical and supraclavicular lymph nodes would not be affected and there are no popliteal lymph nodes.

16. The nurse uses the profile sign during an assessment. What does this technique detect? a. Barrel chest b. Early clubbing c. Symmetry of the fingers d. Insufficient capillary refill

ANS: B The profile sign involves viewing the finger from the side. This is done to detect early clubbing.

19. The nurse is assessing the pulses of a patient who has been admitted for untreated hyperthyroidism. When assessing this patient's pulse, what should the nurse expect? a. Normal b. Bounding c. Weak, thready d. Unpalpable pedal pulse

ANS: B The pulses of a patient with untreated hyperthyroidism are expected to be full or bounding (easily palpable, pounds under your fingertips). Bounding pulses occur with hyperkinetic states (e.g., exercise, anxiety, fever), anemia, and hyperthyroidism. The pedal pulse is likely to be easier to palpate, not unpalpable. An absent pulse occurs with an arterial occlusion and a weak, thready pulse occurs with shock and peripheral artery disease.

1. Which statement is true regarding the arterial system? a. Arteries are large-diameter vessels. b. The arterial system is a high-pressure system. c. The walls of arteries are thinner than those of the veins. d. Arteries can greatly expand to accommodate a large blood volume increase.

ANS: B The pumping heart makes the arterial system a high-pressure system.

4. A 65-year-old patient is experiencing pain in his left calf when he exercises which disappears after resting for a few minutes. What problem in the left leg does this indicate? a. Venous obstruction b. Partial blockage of an artery c. Claudication due to venous abnormalities d. Ischemia caused by the complete blockage of an artery

ANS: B These symptoms indicate ischemia, a deficient supply of oxygenated arterial blood to the tissue, in the leg. A partial blockage creates an insufficient supply and may be apparent only during exercise when oxygen needs increase and is relieved with rest. Although the term for this is claudication, it is due to insufficient arterial blood, not venous abnormalities. With a complete blockage of an artery, the pain would be constant, not just with walking/exercise, and would not be relieved with rest.

22. The nurse is attempting to assess the femoral pulse in a patient who is obese. Which of these actions would be most appropriate? a. Ask the patient to assume a prone position. b. Ask the patient to bend his or her knees to the side in a froglike position. c. The nurse firmly presses against the bone with the patient in a semi-Fowler position. d. The nurse listens with a stethoscope for pulsations; palpating the pulse in an obese person is extremely difficult.

ANS: B To help expose the femoral area, particularly in obese people, the nurse should ask the person to bend his or her knees to the side in a froglike position. This will make accessing the femoral artery easier. The femoral artery is located in the groin area and can be especially difficult to assess in an obese patient. Having the patient assume a prone or Semi-fowler's positions does not help to expose the femoral area and the pulse will unlikely be heard with a stethoscope.

25. A patient has hard, nonpitting edema of the left lower leg and ankle. The right leg has no edema. When interpreting these findings, what should the nurse recall? a. Alterations in arterial function will cause edema. b. Nonpitting, hard edema occurs with lymphatic obstruction. c. Phlebitis of a superficial vein will cause bilateral edema. d. Long-standing arterial obstruction will cause pitting edema.

ANS: B Unilateral edema occurs with occlusion of a deep vein or with unilateral lymphatic obstruction and causes edema that is nonpitting and feels hard to the touch (brawny edema). Alterations in arterial function or long-standing arterial obstruction do not cause lower leg edema nor does phlebitis of a superficial vein. Instead, lower leg edema is caused by problems with the heart or deep veins, lymphatic system, or kidneys.

32. When using a Doppler ultrasonic stethoscope, the nurse recognizes venous flow when which sound is heard? a. Low humming sound b. Swishing, whooshing sound c. Regular "lub, dub" pattern d. Steady, even, flowing sound

ANS: B When using the Doppler ultrasonic stethoscope, the pulse site is found when one hears a swishing, whooshing sound.

20. The nurse is preparing to perform a modified Allen test. Which is an appropriate reason for this test? a. To measure the rate of lymphatic drainage b. To evaluate the adequacy of capillary patency before venous blood draws c. To evaluate the adequacy of collateral circulation before cannulating the radial artery d. To evaluate the venous refill rate that occurs after the ulnar and radial arteries are temporarily occluded

ANS: C A modified Allen test is used to evaluate the adequacy of collateral circulation before the radial artery is cannulated. The other responses are not reasons for a modified Allen test.

33. The nurse is describing a weak, thready pulse on the documentation flow sheet. Which statement is correct? a. "Easily palpable; pounds under the fingertips." b. "Greater than normal force that suddenly collapses." c. "Hard to palpate, may fade in and out, and is easily obliterated by pressure." d. "Rhythm is regular, but force varies with alternating beats of large and small amplitude."

ANS: C A weak, thready pulse is hard to palpate (not easy), may fade in and out, and is easily obliterated by pressure. It is associated with decreased cardiac output and peripheral arterial disease.

35. During a routine office visit, a patient takes off his shoes and shows the nurse "this awful sore that won't heal." On inspection, the nurse notes a 3-cm round ulcer on the left great toe, with a pale ischemic base, well-defined edges, and no drainage. Based on these findings, what does the nurse suspect? a. Varicosities b. Venous stasis ulcer c. Arterial ischemic ulcer d. Deep vein thrombophlebitis

ANS: C Arterial ischemic ulcers occur at the toes, metatarsal heads, heels, and lateral ankle and are characterized by a pale ischemic base, well-defined edges, and no bleeding. Varicosities, or varicose veins, are caused by incompetent distant valves in the veins which produce dilated, tortuous veins. Venous (stasis) ulcers occur at the medial malleolus (not the great toe) and are characterized by bleeding and uneven edges. Deep vein thrombosis is the development of a thrombus, or clot, in a deep vein, most commonly in the legs, that may present with swelling, pain, redness, and warmth. The signs and symptoms this patient has are characteristic of an arterial ischemic ulcer.

15. A patient complains of leg pain that wakes him at night. He states that he "has been having problems" with his legs. He has pain in his legs when they are elevated that disappears when he dangles them. He recently noticed "a sore" on the outer aspect of the right ankle. What do these findings suggest? a. Pain r/t lymphatic abnormalities b. Problems r/t venous insufficiency c. Problems r/t arterial insufficiency d. Pain r/t musculoskeletal abnormalities

ANS: C Night leg pain is common in aging adults and may indicate the ischemic rest pain of peripheral arterial disease (PAD). Alterations in arterial circulation cause pain that becomes worse with leg elevation and is eased when the extremity is dangled. In addition, ulcers associated with PAD, or arterial ulcers, often occur on the lateral ankle (as in this patient), toes, metatarsal heads, and heels.

17. The nurse is performing an assessment on an adult. The adult's vital signs are normal, and capillary refill time is 5 seconds. What should the nurse do next? a. Ask the patient about a history of frostbite. b. Suspect that the patient has venous insufficiency. c. Consider this a delayed capillary refill time, and investigate further. d. Consider this a normal capillary refill time that requires no further assessment.

ANS: C Normal capillary refill time is less than 1 to 2 seconds. A capillary refill time of 5 is a decrease in capillary refill which indicates vasoconstriction or decreased cardiac output. The nurse should investigate further. Decreased capillary refill is not a characteristic of previous frostbite or venous insufficiency and some conditions can skew the findings: a cool room, decreased body temperature, cigarette smoking, peripheral edema, and anemia.

31. The nurse is performing a well-child checkup on a 5-year-old boy. The child has no current condition that would lead the nurse to suspect an illness. His health history is unremarkable, and he received immunizations 1 week ago. Which of these findings should be considered normal in this patient? a. Enlarged, warm, and tender nodes b. Lymphadenopathy of the cervical nodes c. Palpable firm, small, shotty, mobile, and nontender lymph nodes d. Firm, rubbery, and large nodes, somewhat fixed to the underlying tissue

ANS: C Palpable lymph nodes are often normal in children and infants and are small, firm, shotty (firm), mobile, and nontender. Vaccinations can produce lymphadenopathy and enlarged, warm, and tender nodes would indicate an infection both of which would not be considered a normal finding.

18. When performing a peripheral vascular assessment on a patient, the nurse is unable to palpate the ulnar pulses. The patient's skin is warm and capillary refill time is normal. What should the nurse do next? a. Check for the presence of claudication. b. Refer the individual for further evaluation. c. Consider this finding normal, and proceed with the peripheral vascular evaluation. d. Ask the patient if he or she has experienced any unusual cramping or tingling in the arm.

ANS: C Palpating the ulnar pulses is not usually necessary and they are not often palpable in the normal person. There is no need to check for claudication, refer for further evaluation, or ask about cramping and tingling in the arm.

13. During an assessment of an older adult, the nurse should expect to which finding as a normal physiologic change associated with the aging process? a. Hormonal changes causing vasodilation and a resulting drop in blood pressure b. Progressive atrophy of the intramuscular calf veins, causing venous insufficiency c. Peripheral blood vessels growing more rigid with age, producing a rise in systolic blood pressure d. Narrowing of the inferior vena cava, causing low blood flow and increases in venous pressure resulting in varicosities

ANS: C Peripheral blood vessels become more rigid with age, resulting in a rise in systolic blood pressure. Aging produces progressive enlargement of the intramuscular calf veins, not atrophy. The other options are not correct. Although older age does increase the risk for varicose veins, it is due to the thinning of elastic lamina of veins and degeneration of vascular smooth muscle, not narrowing of the inferior vena cava.

2. The nurse is reviewing the blood supply to the arm. What major artery supplies blood to the arm? a. Ulnar b. Radial c. Brachial d. Deep palmar

ANS: C The major artery supplying blood to the arm is the brachial artery. The brachial artery bifurcates into the ulnar and radial arteries immediately below the elbow. In the hand, the ulnar and radial arteries form two arches known as the superficial and deep palmar arches.

36. The nurse is reviewing an assessment of a patient's peripheral pulses and notices that the documentation states that the radial pulses are "2+." The nurse recognizes that this reading indicates what type of pulse? a. Weak b. Absent c. Normal d. Bounding

ANS: C When documenting the force, or amplitude, of pulses, 3+ indicates an increased, full, or bounding pulse, 2+ indicates a normal pulse, 1+ indicates a weak pulse, and 0 indicates an absent pulse.

21. A patient has been diagnosed with venous stasis. Which of these findings would the nurse most likely observe? a. Unilateral cool foot b. Thin, shiny, atrophic skin c. Pallor of the toes and cyanosis of the nail beds d. Brownish discoloration to the skin of the lower leg

ANS: D A brown discoloration occurs with chronic venous stasis as a result of hemosiderin deposits (a by-product of red blood cell degradation). Pallor, cyanosis, atrophic skin, and unilateral coolness are all signs associated with arterial problems.

23. When auscultating over a patient's femoral arteries, the nurse notices the presence of a bruit on the left side. Which statement about bruits is accurate? a. Often associated with venous disease b. Occur in the presence of lymphadenopathy c. Femoral artery bruits are caused by hypermetabolic states d. Occur with turbulent blood flow, indicating partial occlusion

ANS: D A bruit occurs with turbulent blood flow and indicates partial occlusion of the artery. The other responses are not correct.

7. A 70-year-old patient is scheduled for open-heart surgery. The surgeon plans to use the great saphenous vein for the coronary bypass grafts. The patient asks, "What happens to my circulation when this vein is removed?" How should the nurse reply? a. "Venous insufficiency is a common problem after this type of surgery." b. "Oh, you have lots of veins—you won't even notice that it has been removed." c. "You will probably experience decreased circulation after the vein is removed." d. "This vein can be removed without harming your circulation because the deeper veins in your leg are in good condition."

ANS: D As long as the femoral and popliteal veins remain intact, the superficial veins can be excised without harming circulation. The other responses are not correct. Venous insufficiency or decreased circulation is not a common problem with this procedure. The nurse should not just say "you won't even notice" but should provide more factual information.

26. When assessing a patient's pulse, the nurse notes that the amplitude is weaker during inspiration and stronger during expiration. When the nurse measures the blood pressure, the reading decreases 20 mm Hg during inspiration and increases with expiration. What do these findings indicate? a. Pulsus alternans b. Pulsus bisferiens c. Pulsus bigeminus d. Pulsus paradoxus

ANS: D In pulsus paradoxus, beats have weaker amplitude with inspiration and stronger amplitude with expiration and is best determined during blood pressure measurement; reading decreases (>10 mm Hg) during inspiration and increases with expiration. In pulsus alternans, the rhythm is regular, but force varies, with alternating beats of large and small amplitude. In pulsus bisferiens, each pulse has two strong systolic peaks with a dip in between and is best assessed at the carotid artery. In pulsus bigeminus, the beats are coupled, every other beat comes early, or normal beat is followed by a premature beat. The force of the premature beat is decreased because of shortened cardiac filling time. This patient's weaker amplitude during inspiration and stronger during expiration is pulsus paradoxus.

3. The nurse is preparing to assess the dorsalis pedis artery. Where is the correct location for palpation? a. Behind the knee b. Over the lateral malleolus c. In the groove behind the medial malleolus d. Lateral to the extensor tendon of the great toe

ANS: D The dorsalis pedis artery is located on the dorsum of the foot. The nurse should palpate just lateral to and parallel with the extensor tendon of the big toe. The popliteal artery is palpated behind the knee. The posterior tibial pulse is palpated in the groove between the malleolus and the Achilles tendon. No pulse is palpated at the lateral malleolus.

10. When performing an assessment of a patient, the nurse notices the presence of an enlarged right epitrochlear lymph node. What should the nurse do next? a. Assess the patient's abdomen, and notice any tenderness. b. Carefully assess the cervical lymph nodes, and check for any enlargement. c. Ask additional health history questions regarding any recent ear infections or sore throats. d. Examine the patient's lower arm and hand, and check for the presence of infection or lesions.

ANS: D The epitrochlear nodes are located in the antecubital fossa and drain the hand and lower arm. The nurse should examine the patient's lower arm and hand, and check for the presence of infection or lesions. The other actions are not correct for this assessment finding. The epitrochlear nodes are located in the antecubital fossa and drain the hand and lower arm, thus, there is no need to assess the patient's abdomen, cervical lymph nodes, or ask about recent ear infections or sore throats based on an enlarged epitrochlear lymph node. Instead, the nurse should examine the patient's lower arm and hand, and check for the presence of infection or lesions.

6. Which vein(s) is(are) responsible for most of the venous return in the arm? a. Deep b. Ulnar c. Subclavian d. Superficial

ANS: D The superficial veins of the arms are in the subcutaneous tissue and are responsible for most of the venous return.

30. The nurse is preparing to assess the ankle-brachial index (ABI) of a patient. Which statement about the ABI is true? a. Normal ABI indices are from 0.5 to 1.0. b. Normal ankle pressure is slightly lower than the brachial pressure. c. The ABI is a reliable measurement of peripheral vascular disease in individuals with diabetes. d. An ABI of 0.9 to 0.7 indicates the presence of peripheral vascular disease and mild claudication.

ANS: D Use of the Doppler stethoscope is a noninvasive way to determine the extent of peripheral vascular disease. The normal ankle pressure is slightly greater than or equal to the brachial pressure. An ABI of 0.9 to 0.7 indicates the presence of peripheral vascular disease and mild claudication. The ABI is less reliable in patients with diabetes mellitus because of claudication, which makes the arteries noncompressible and may give a false high-ankle pressure.
