HA, Chapter 20

A female client being examined by the nurse exhibits 2+ pitting edema in the right arm, while the left arm is normal in size. Which question by the nurse is the most appropriate based on this data? 1. "How much salt do you have in your diet?" 2. "Does the other arm swell also?" 3. "What surgical procedures have you had?" 4. "Do you ever feel self-conscious about your arm?"

Correct Answer: 3 Global Rationale: This client most likely has lymphedema. Damage to or removal of lymph nodes can impact the ability of the lymph system to drain the arm adequately, so information about previous surgical procedures is the priority question. This information will help the nurse determine if the client has lymphedema due to a surgical procedure. If salt intake was excessive, the nurse would also find swelling in other extremities. Unilateral swelling indicates that there may be a problem with lymph drainage from the extremity. The client's feelings of being self-conscious are important for the nurse to consider, but are not the most important at this time. The nurse should seek to determine how the lymphedema developed.

The nurse is assessing a client admitted to the hospital for congestive heart failure (CHF) and notes 1+ pitting edema of the left arm, as well as bilateral 1+ pitting edema in the client's ankles. The client's history indicates that the client has had a myocardial infarction and a left mastectomy. Which is the most probable cause of the edema in the client's left arm? 1. Impaired lymphatic drainage. 2. Noncompliance with medication regimen. 3. Right-sided heart failure. 4. Excessive intake of sodium.

Correct Answer: 1 Global Rationale: This client most likely has developed lymphedema due to the removal of lymph nodes during the client's mastectomy. This type of surgery can inhibit the body's ability to drain lymph from the client's affected arm. Noncompliance with medication may result in edema that affects the client's bilateral peripheral extremities. Unilateral edema indicates that there is a problem with the way the lymph is able to drain from the client's extremity. Right-sided heart failure often results in bilateral pitting edema. Unilateral pitting edema indicates that the lymph is not draining well from the client's arm. Increased sodium intake can result in edema; however, this would most likely result in bilateral peripheral edema.

While performing the assessment of the client's peripheral vascular system, the nurse notes that there was a rapid filling of superficial veins during the Trendelenburg test. This data is consistent with which disorder? 1. Valve incompetence. 2. Arterial insufficiency. 3. Venous insufficiency. 4. Phlebitis.

Correct Answer: 1 Global Rationale: This finding is consistent with valve incompetence that is associated with the development of varicose veins in the lower extremities. The Trendelenberg test does not test for arterial insufficiency. The findings are not consistent with venous insufficiency. The client with venous insufficiency will exhibit edema and a brownish discoloration in the lower extremities. Phlebitis is an inflammation of the vein. The Trendelenberg test is not used to determine if the client has phlebitis. The client with phlebitis will complain of tenderness along the affected area of the vein.

The nurse is preparing to assess the client's dorsalis pedis pulse. Which location will the nurse palpate to assess this pulse? 1. A. 2. B. 3. C. 4. D.

Correct Answer: 4 Global Rationale: The dorsalis pedis pulses may be felt on the medial side of the dorsum of the foot.

An adult female client wishes to begin taking oral contraceptives. The medical history indicates that the client had a deep vein thrombosis three years ago. After reviewing the objectives set forth in Healthy People 2020, which response by the nurse is the most appropriate? 1. "We can have the healthcare provider write you a prescription today." 2. "You will also have to take blood thinners." 3. "I need to perform a Homan's test on you." 4. "Taking oral contraceptives increases your risk of developing clots."

Correct Answer: 4 Global Rationale: This client has a history of deep vein thrombosis. Her history and oral contraceptive use increases her risk for developing another thrombosis. It would be better for this client to avoid using oral contraceptives and use another method of birth control. "Blood thinners'' have significant side effects. There is no information to indicate the client currently has a deep vein thrombosis so Homan's test is not appropriate.

The nurse is thoroughly assessing the client for any peripheral vascular problems. The client requested the nurse to state exactly what the nurse was looking for during the assessment. Which statements by the nurse are appropriate to include in the assessment process? Standard Text: Select all that apply. 1. "I am feeling your feet to see how warm they are." 2. "I am looking for hair on your toes." 3. "I am going to perform the Trendelenburg's test to see how well the radial and ulnar arteries are supplying blood to your hand." 4. "I am going to test your ability to feel sensations by giving you an injection." 5. "I am going to perform the Allen's test to see if you have any varicose veins."

Correct Answer: 1, 2 Global Rationale: It is important for the nurse to assess the client's peripheral extremities to determine temperature. Hair growth on toes indicates adequate arterial blood flow. The Allen's test is used to determine patency of the radial and ulnar arteries. The nurse should use a safety pin to assess the client's ability to feel dull and sharp sensations. The Trendelenburg's test can be used to determine if the client has varicose veins in the legs.

The nurse is caring for a male client who is complaining of dizziness when standing. The client has been compliant with his antihypertensive medication. Which statements made by the client are commonly associated with the use of antihypertensive medication? Standard Text: Select all that apply. 1. "Sometimes, I just feel so sick to my stomach." 2. "I have frequent headaches." 3. "My sex life hasn't been so good since I started taking this medication." 4. "I have a rash all over my back." 5. "I don't seem to urinate as much as I did before I started this medication."

Correct Answer: 1, 2, 3 Global Rationale: Nausea and headaches are associated with antihypertensive medication use. Clients who use antihypertensive medications to control their blood pressure might experience a decrease in their sex drive. Impotence can occur in male clients. Rashes are not necessarily commonly associated with antihypertensive medication use. Clients who take diuretics to control their blood pressure may find that they are voiding more than usual. This is not found with antihypertensive medications other than diuretics.

The nurse is assessing a client who may have arterial insufficiency in the left lower leg. Which assessment findings support the diagnosis of arterial insufficiency? Standard Text: Select all that apply. 1. Left dorsalis pedis pulse +1, right dorsalis pedis pulse +3. 2. Skin is cool, tight, and shiny. 3. When left leg is dependent, erythema is present. 4. When left leg is elevated, pallor is present. 5. Client complains of increased pain during rest periods.

Correct Answer: 1, 2, 3, 4 Global Rationale: The client with arterial insufficiency may have diminished pulses. The pulse in the left foot is difficult to palpate, but the pulse in the right foot is strong and easy to palpate. The affected limb will feel cool. The skin may look "tight" and appear shiny. These findings indicate that the limb is not receiving an adequate arterial supply of oxygenated blood. When in a dependent position, the affected limbs will become reddened. When elevated, affected limbs will become pale. The client with arterial insufficiency is more likely to complain of pain during exercise of the leg. The pain decreases or is absent with rest.

The nurse is performing a focused interview with a client who was recently diagnosed with varicose veins. Which statements by the client will the nurse document as risk factors for varicose vein development? Standard Text: Select all that apply. 1. "My mother had big veins on her legs from the time I was little." 2. "My father is of Japanese descent." 3. "I'm a hair stylist." 4. "I was pregnant once and have a son." 5. "I know I weigh a lot more than I should."

Correct Answer: 1, 3, 4, 5 Global Rationale: A client who has a family history of varicose veins has an increased risk for developing them. Hair stylists are more likely to be on their feet while they are working and this does result in an increase in their risk of developing varicose veins. People who have been pregnant multiple times have an increased risk for developing varicose veins. People who are obese have an increased risk for developing varicose veins. Risk factors for varicose veins include people who are of Irish or German descent. People of Japanese descent do not necessarily have an increased risk of developing varicose veins.

The nurse is performing an assessment on a healthy preschool-age client and palpates two enlarged lymph nodes on the child's neck. The lymph nodes are soft, mobile, nontender, and each is less than 1 cm in diameter. Which action by the nurse is the most appropriate? 1. Assess for an infected wound. 2. Document this as a normal finding. 3. Notify the healthcare provider. 4. Obtain an order for a throat culture.

Correct Answer: 2 Global Rationale: It is a normal finding to determine that a child has several enlarged lymph nodes less than 1cm such as these. When lymph nodes are significantly enlarged, greater than 1cm, the nurse should assess the child for an infection. Documenting this as a normal finding is appropriate since these enlarged lymph nodes are small, less than 1cm, nontender, and mobile. It is not necessary for the nurse to notify the healthcare provider at this time. Obtaining an order for a throat culture would be an appropriate nursing action if the child had significantly enlarged lymph nodes and evidence that an infection was present in the child's pharynx.

The client is visiting the healthcare provider's office with complaints of discoloration of her hands. The client states, "My fingertips turn whitish and then later they get really red." Which disorder does the nurse anticipate the client will be diagnosed with based on this data? 1. Lymphedema. 2. Raynaud disease. 3. Thrombosis. 4. Venous insufficiency.

Correct Answer: 2 Global Rationale: The findings described are consistent with Raynaud disease, in which the arterioles in the fingers develop spasms, causing intermittent skin pallor or cyanosis, then redness. This condition is most commonly seen in young females. Lymphedema is often described as edema that occurs in an affected extremity that is not draining lymph properly. Clients with clots may have no symptoms at all or may experience pain. Venous insufficiency results in discomfort that is aggravated by prolonged standing or sitting and is relieved by rest. The client's complaints are not consistent with venous insufficiency.

The nurse is completing an assessment on a client following a cardiac catheterization procedure. During the initial assessment, the nurse easily palpates the client's right dorsalis pedis and posterior tibial pulses. The pulses on the client's left leg are strong and easily palpable. During the next assessment, the nurse is unable to palpate or find these pulses on the right side with a Doppler. Which is the priority action by the nurse based on this data? 1. Notify the healthcare provider immediately. 2. Assess for the client's right popliteal pulse. 3. Take the client's blood pressure. 4. Place the client in Trendelenburg position.

Correct Answer: 2 Global Rationale: The nurse should attempt to palpate the client's popliteal pulse. This will help the nurse determine how much of this extremity is still receiving oxygenated blood. After the nurse assesses the client's popliteal pulses, it may be appropriate to check the client's vital signs prior to notifying the healthcare provider. The healthcare provider should be notified, but the nurse should be prepared to provide information about the client's condition during their conversation. Trendelenberg can be used to treat a client in shock. The information about the client does not indicate that the client has developed clinical manifestations associated with shock.

A client's blood pressure is 138/86 mmHg. Which will the nurse use when documenting this finding in the client's medical record? 1. The client has normal blood pressure. 2. The client is exhibiting prehypertension. 3. The client is exhibiting stage I hypertension. 4. The client is exhibiting stage II hypertension.

Correct Answer: 2 Global Rationale: This blood pressure is classified as prehypertension because it is between 130 and 139 (systolic) and 80 and 89 (diastolic). Normal blood pressures are less than 120 (systolic) and less than 80 (diastolic). Blood pressures falling into the Stage I hypertension category are those between 140 and 159 (systolic) or those between 90 and 99 (diastolic). Blood pressures falling into the stage II hypertension category are those greater than or equal to 160 (systolic) or greater than 100 (diastolic).

While performing a focused interview with a healthy adult client, the nurse notes frequent position changes, wringing of hands, lack of eye contact, incomplete sentences, and rapid speech. The vital signs are BP 160/88 mmHg, apical pulse 102 beats per minute, respiratory rate 26 per minute. Which responses by the nurse are appropriate in this situation? Standard Text: Select all that apply. 1. "I'm going to take your temperature now." 2. "Have you ever experienced chest pain?" 3. "Are you feeling any anxiety right now?" 4. "Are you experiencing any pain at this time?" 5. "Have you ever been diagnosed with hypothyroidism?"

Correct Answer: 2, 3, 4 Global Rationale: The client's actions may indicate that the client is experiencing pain. The client may be experiencing chest pain. The nurse should determine whether the client is experiencing chest pain prior to continuing the focused interview. Pain can result in increased blood pressure, pulse, and respiratory rate. The nurse should determine if the client is experiencing pain and seek to treat the pain prior to continuing with the focused interview. The client's actions are also consistent with anxiety. Anxiety stimulates the sympathetic nervous system, which can result in vasoconstriction, high blood pressure, increased heart rate, and respiratory rate. It will be appropriate to assess the client's temperature, but the nurse should first determine whether the client is in pain or is experiencing anxiety. The client's vital signs and actions are more likely associated with hyperthyroidism.

The nurse is performing the assessment of an older adult client recently diagnosed with arterial insufficiency due to atherosclerosis. Which assessment data does the nurse expect when examining this client? Standard Text: Select all that apply. 1. Bilateral pitting edema 3+ in ankles and feet. 2. Carotid bruit present. 3. Blood pressure 180/94. 4. Peripheral pulses 1+/4+ in dorsalis pedis bilaterally. 5. A pea-sized ulcer noted on the client's right great toe, no drainage, well-defined edges.

Correct Answer: 2, 3, 4, 5 Global Rationale: A narrowing of the carotid artery, as occurs with atherosclerosis, will result in turbulent blood flow. This causes the swishing sound known as a bruit. Clients with atherosclerosis and arterial insufficiency may have hypertension. Atherosclerosis and arterial insufficiency may result in decreased peripheral pulses. The client with arterial insufficiency may develop ulcers such as this one. Bilateral pitting edema is most often attributed to right-sided heart failure.

An adult female client develops a pulmonary embolism and is admitted to the intensive care unit (ICU). While completing the client's health history interview, which data is consistent with the admitting diagnosis of pulmonary embolism? Standard Text: Select all that apply. 1. Client states, "I am not a smoker." 2. Client states, "The nurse on the surgical unit really wanted me to sit on the side of the bed after surgery and to start walking with him later that evening, but I was so nauseated and in so much pain that I couldn't." 3. Client states, "I had an open appendectomy 4 days ago." A 4 cm incision noted to RLQ, staples intact, edges well-approximated. 4. Client states, "I have taken oral contraceptives for the last 7 years." 5. Client states, "I had some muscle cramping and tenderness in my left leg before they moved me to Intensive Care."

Correct Answer: 2, 3, 4, 5 Global Rationale: Ambulating after surgery is important to help prevent blood clots from forming. Major surgeries can increase the client's risk for developing a blood clot. Oral contraceptive use can increase the client's risk for clotting. The client most likely had a deep vein thrombosis before the pulmonary embolism developed. Smoking cigarettes can increase the client's risk for developing a deep vein thrombosis that can turn into a pulmonary embolism.

The nurse educator is teaching a group of nursing students how to perform an assessment of the client's peripheral vascular system. Which student statements indicate an appropriate understanding of the peripheral vascular assessment? Standard Text: Select all that apply. 1. "I need to take a blood pressure only in the client's right arm." 2. "The best way to assess the carotid pulses is palpate one side and then the other." 3. "It will be easier to assess the client's carotid pulses if the client is obese." 4. "I should inspect the arms to ensure that they are close to the same size." 5. "I should look at the extremities to ensure that hair distribution is normal and symmetrical. The skin should be clean and free of any lesions."

Correct Answer: 2, 4, 5 Global Rationale: The best way to palpate the client's carotid pulses is separately, not simultaneously. The student nurse should ensure that both arms are equal in size. The student nurse should thoroughly assess the client's extremities. The student nurse should take the client's blood pressure in both arms and both legs. It will be more difficult to assess the client's carotid pulses if the client is obese or has a short neck.

The client was recently diagnosed with venous insufficiency. Which client statements support the client's diagnosis? Standard Text: Select all that apply. 1. "My legs are so cold that they feel like ice." 2. "My ankles and feet are always swollen." 3. "The skin on my leg looks so pale." 4. "When I walk around a lot, my legs just ache." 5. "I have an ulcer on my inner leg above my ankle that just bleeds and bleeds."

Correct Answer: 2, 5 Global Rationale: Edema in the lower extremities is associated with venous insufficiency. The ulcers consistent with a diagnosis of venous insufficiency are likely to bleed and can be found in this area of the lower extremity. Arterial insufficiency ulcers are often described as dry, pale, with defined edges. Clients with arterial insufficiency may complain that their legs feel cool or cold. The nurse is more likely to determine that the legs of clients with venous insufficiency have temperatures that are within normal limits. Pale skin on the lower extremities is associated with arterial insufficiency. Venous insufficiency results in darkened skin on the lower extremities. Pain with walking is consistent with a client who has been diagnosed with arterial insufficiency. The type of discomfort associated with venous insufficiency is aggravated by prolonged standing or sitting and is relieved by several hours of rest.

The nurse is educating a client about blood pressure values. Which statement by the client indicates appropriate understanding of the teaching session? 1. "A normal blood pressure always depends on my previous blood pressure values." 2. "A normal blood pressure is below 140/90." 3. "If I was diagnosed with prehypertension my blood pressure would be 138/89." 4. "A diagnosis of prehypertension does not increase my risk of developing hypertension."

Correct Answer: 3 Global Rationale: A client with prehypertension will have a blood pressure of 120-139 (systolic) and 80-89 (diastolic). There are some specific guidelines set forth by the National Institutes of Health that can be used to classify a client's blood pressure as "normal," "prehypertension," "stage I hypertension," and "stage II hypertension." A normal blood pressure is actually less than 120 (systolic) and less than 80 (diastolic). Client's diagnosed with prehypertension are at an increased risk for developing hypertension.

The nurse is assessing the blood pressure of a client. The nurse obtains the blood pressure in both of the client's arms. The nurse determines that there is a difference of 15 mmHg in the systolic readings between the arms and repeats the assessment with the same results. Based on this data, which does the nurse suspect? 1. Inaccurate technique. 2. Anxiety. 3. Unilateral arterial obstruction. 4. Shock.

Correct Answer: 3 Global Rationale: A difference of readings 10 mmHg or more between arms may indicate an obstruction of arterial blood flow to one arm and is considered an abnormal finding. After repeating the procedure and determining the results were the same, the nurse would not necessarily assume that the technique was faulty. Client anxiety may result in a higher blood pressure reading. It would not result in a difference between blood pressures assessed in each arm. If the client is developing clinical manifestations associated with shock, the nurse would most likely determine that the client's blood pressure is lower than normal. Shock would not result in a difference between blood pressures assessed in each arm.

The nurse is assessing a client's blood pressure. The client asks the nurse why it is important to feel for his pulse prior to taking his blood pressure. Which response by the nurse is the most appropriate? 1. "I can document this value if I am unable to measure your blood pressure the other way." 2. "I need to feel for your pulse because you doctor said you are developing symptoms of shock." 3. "I am more likely to get an accurate reading if I do it this way." 4. "It is the best way to determine an arterial obstruction."

Correct Answer: 3 Global Rationale: Assessing the palpable systolic pressure helps to avoid inaccuracy in blood pressure assessment that can occur with an ausculatory gap, or space in which beats are not heard, during this assessment. It is not appropriate to merely document the palpable systolic pressure. Efforts should be made to document the client's blood pressure. When a client is developing clinical manifestations associated with shock, his blood pressure is more likely to be lower than normal. The nurse should palpate the systolic pressure for all clients regardless of their diagnoses. Arterial obstruction can be assessed by measuring the difference between the blood pressures in the arms. A difference of 10 mmHg or more between the arms may indicate an obstruction of arterial flow to one arm.

The nurse is performing a peripheral vascular assessment of a female client who is 7 months pregnant. The nurse notes mild peripheral edema, all other findings were normal. Which action by the nurse is appropriate based on this assessment data? 1. Notify the healthcare provider immediately regarding this abnormal finding. 2. Obtain an order from the healthcare provider for a diuretic to reduce the client's edema. 3. Document the findings as expected due to the client's pregnancy. 4. Educate the client regarding ways to reduce the risk about peripheral vascular ulcer development.

Correct Answer: 3 Global Rationale: Pressure from the uterus on the lower extremities can obstruct venous return and can cause edema, varicosities of the leg, and hemorrhoids. Mild peripheral edema is an expected finding when a pregnant client is in her third trimester. The client's healthcare provider does not need to be immediately notified. The client does not need a diuretic to reduce the mild peripheral edema. This client is not necessarily at a greater risk for developing a peripheral vascular ulcer.

The client developed a pulmonary embolism. In which most distal area of the lower extremity did the embolism likely originate? 1. A. 2. B. 3. C. 4. D.

Correct Answer: 3 Global Rationale: The client is more likely to have developed a blood clot within the calf. Blood clots can develop in the popliteal area as well but this site is less distal than the calf.

The nurse examines the peripheral vascular system of a client diagnosed with chronic bronchitis 22 years ago. The nurse examines the client's hand. Which statement by the client is consistent with the client's diagnosis? 1. "My fingers look so pointy and narrow at the ends." 2. "My fingernails are as hard as a rock." 3. "My nails always look a little bluish." 4. "My nails have a lot of strange ridges in them."

Correct Answer: 3 Global Rationale: The statement regarding blueness is a likely statement from someone who has a long history of disorder resulting in chronic hypoxia. The nails may look blue or gray due to oxygen deprivation. Many times, clients with a long-term history of chronic hypoxia such as chronic bronchitis, will exhibit clubbing of their fingers. The fingertips will look large at the ends, not pointy and narrow. Clients with lung problems resulting in chronic hypoxia will more likely to complain that their nails are soft and spongy. Ridges in the nails are more likely the result of another disorder such as a nutritional deficiency.

While assessing a client with a laceration on the client's left third finger, the nurse notes the presence of inflammation and swelling of the finger. Which other assessment findings might the nurse expect based on this initial data? Standard Text: Select all that apply. 1. 1 cm, nontender, soft, left brachial node. 2. 2 cm, tender, firm, left superior superficial inguinal node. 3. 2 cm, tender, firm, left epitrochlear node. 4. 2 cm, nontender, firm, left ulnar node. 5. 2 cm, tender, firm, left axillary lymph node.

Correct Answer: 3, 5 Global Rationale: Normally, the epitrochlear nodes are not palpable. A tender, firm, and enlarged node such as this one may indicate the client has an infection. The epitrochlear node drains the forearm and third, fourth, and fifth fingers. The client with an infected wound on the left finger may have a tender enlarged lymph node in the axilla that can be found with light palpation. A lymph node indicative of infection will be greater than 1 cm, tender, and mobile. The left superior superficial inguinal node drains lymph from the client's left leg. The epitrochlear node, not the ulnar node, drains lymph from the ulnar area. Lymph nodes in the arm are the following: subclavicular, central axillary, brachial, and epitrochlear.

The nurse is performing an assessment of the client's peripheral vascular system. Which actions by the nurse are appropriate when assessing this client? 1. Assessing the client in a flat, supine position when the client exhibits a respiratory rate of 26 breaths/min. with a dusky appearance around the mouth and lips. 2. Requesting the client remove all undergarments prior to putting the gown. 3. Assessing pedal pulses over the client's socks. 4. Taking a blood pressure cuff, Doppler, and stethoscope into the client's room for the assessment.

Correct Answer: 4 Global Rationale: A blood pressure cuff, Doppler, and stethoscope are appropriated pieces of equipment for the nurse to bring into the room for the assessment of this client. The student nurse must pay attention to how well the client tolerates the various positions during the assessment. The client needs to remove only socks and shoes prior to putting on the gown. The socks must be removed to accurately assess the peripheral vascular system.

The nurse is conducting a wellness presentation for a group of factory employees and notes a large number of African Americans present. Based on information included in Healthy People 2020, which topic is a priority for this population? 1. Cancer risk reduction. 2. Bone density assessments. 3. Smoking cessation. 4. Blood pressure screening.

Correct Answer: 4 Global Rationale: African Americans have an increased risk of developing hypertension, so blood pressure screening would be an appropriate activity. African Americans do not typically have an increased risk of all types of cancers or of developing osteoporosis. Smoking cessation techniques are important to discuss, but hypertension is something that affects many African Americans.

The nurse is documenting an ulcer on the lateral aspect of the client's right great toe. The nurse notes that the ulcer is pale with well-defined edges and there is no evidence of bleeding. Which other assessment data would be useful to determine the origin of this client's ulcer? 1. Skin turgor. 2. Calf measurements. 3. Homan's sign. 4. Peripheral pulses.

Correct Answer: 4 Global Rationale: Peripheral pulses should be assessed to determine if the client has arterial insufficiency. This is the most useful assessment at this time. The nurse can use information about the client's skin turgor to help assess the client's fluid balance. Calf measurements can be compared to determine if the client is developing edema. This information will be more helpful to use with a client who has venous insufficiency. Homan's sign can be used to help determine if the client has developed a deep vein thrombosis.

The nurse is caring for a client who may have an arterial obstruction in her right ulnar artery. Which test may be used to help determine the patency of this artery? 1. Trendelenburg test. 2. Manual compression test. 3. Homan sign. 4. Allen test.

Correct Answer: 4 Global Rationale: The Allen test is used to evaluate the patency of both the radial and ulnar arteries. The Trendelenberg test can be used to evaluate valve competence in the presence of varicosities. If varicose veins are present, the nurse can determine the length of the varicose vein and the competency of its valves with the manual compression test. The test to elicit a Homan sign can be used to help determine if the client has a thrombosis.

A client presents with an enlargement of several cervical lymph nodes and asks the nurse about the function of these structures. Which response by the nurse is the most appropriate? 1. "Your lymph nodes filter blood for your body." 2. "They are responsible for the break down of old red blood cells." 3. "They make lymphocytes for you." 4. "Your lymph nodes help to remove infectious organisms."

Correct Answer: 4 Global Rationale: The lymph fluid is filtered in the lymph node to remove pathogens before returning it the bloodstream. The liver is responsible for breaking down old red blood cells. Lymphocytes are not made in lymph nodes. Lymph nodes filter lymph fluid before returning it the blood.
