OA, Fractures

18. A patient had hip surgery. On the second post-op day, the patient is agitated, is tremulous and confused. What should the nurse primarily assess? a) the surgical wound b) alcohol use before surgery c) peripheral circulation d) breathing pattern

18) B - the client's sign and symptoms indicate alcohol withdrawal.

25. Which of the following complications does the nurse suspect when a client had fracture of the femur and is now experiencing respiratory distress? a) sepsis b) fat embolism c) bleeding d) shock

25) B - fat embolism is a common complication of fracture of the long bones, like fracture of the femur. Yellow marrow is released into the circulation and reaches the pulmonary circulation. Acute respiratory distress syndrome may occur.

26. Which among these clients is at highest risk for developing low back pain? a) the man working with a drill hammer b) the man delivering mails in the building c) the salesman selling truck tires d) the man washing windows of a building

26) A - dealing with drill hammer puts strain at the back more than the other jobs mentioned.

27. The client had been diagnosed to have fracture of the tibia after a motorcycle accident. Few hours after, he complains of pain distal to the injury, with numbness and tingling sensation. The nurse notes pallor and coolness of the extremity with absent distal pulse. What complication of fracture does the nurse identify in this client?

27) Compartment Syndrome - compression and edema of the content of the compartment (blood vessels, nerves, and muscles) leads to five p's - pain, pallor, pulselessness, paresthesia, paralysis.

30. Which of the following factors should concern the nurse most in a client who had undergone total hip replacement? a) the client has a small dog and a cat at home b) the client goes for a walk in the park each morning c) the client showers instead of having tub bath d) the client uses raised toilet seat

30) A - bending and stooping like taking care of a small dog and a cat, may cause dislodgement of the hip prosthesis.

33. The nurse notes that the client on cast has diminished distal pulse. Which of the following is the most appropriate nursing action? a) check the client's vital signs b) get doppler and check for distal pulse c) elevate the affected feet d) notify the physician

33) D - diminished distal pulse in an extremity on cast indicates that the cast is too tight. This leads to circulatory impairment. Therefore, the physician should be notified. Bivalving/splitting of the cast will be done by the physician to prevent necrosis and gangrene formation.

51. A client has a fiberglass (nonplaster) cast applied to the lower leg. The client asks the nurse when the client will be able to walk using the casted leg. The nurse replies that the client will be able to bear weight on the casted leg: a) in 48 hours b) in 24 hours c) in about hours d) within 20 to 30 minutes of application

51) D - A fiberglass cast is made of water-activated polyurethane materials that are dry to the touch within minutes and reach full rigid strength in about 20 minutes. Because of this, the client can bear weight on the cast within 20 to 30 minutes.

53. A client with a hip fracture asks the nurse why Buck's extension traction is being applied before surgery. The nurse's response is based on the understanding that Buck's extension traction primarily: a) allows bony healing to begin before surgery b) provides rigid immobilization of the fracture site c) lengthens the fractured leg to prevent severing of blood vessels d) provides comfort by reducing muscle spasms and provides fracture immobilization

53) D - Buck's extension traction is a type of skin traction often applied after hip fracture before the fracture is reduced in surgery. Traction reduces muscle spasms and helps immobilize the fracture. Traction does not lengthen the leg for the purpose of preventing blood vessel severance. Traction also does not allow for bony healing to begin.

60. The nurse is assessing the casted extremity of a client for signs of infection. Which of the following findings is indicative of infection? a) dependent edema b) diminished distal pulse c) coolness and pallor of the skin d) presence of a "hot spot" on the cast

60) D - Signs and symptoms of infection under a casted area include a musty odor or purulent drainage from the cast or the presence of "hot spots," which are areas on the cast that are warmer than others. The physician should be notified if any of these occur.

64. A nurse is caring for a client who has been placed in Buck's extension traction. The nurse provides for countertraction to reduce shear and friction by: a) using a footboard b) providing an overhead trapeze c) slightly elevating the foot of the bed d) slightly elevating the head of the bed

64) C - The part of the bed under an area in traction is usually elevated to aid in countertraction. For the client in Buck's extension traction (which is applied to a leg), the foot of the bed is elevated. An overhead trapeze or footboard is not used to provide countertraction. Option C provides a force that opposes the traction force effectively without harming the client.

77. The nurse is assigned to care for a client who is in traction. The nurse ensures a safe environment for the client by: a) making sure that the knots are at the pulleys b) checking the weights to be sure that they are off the floor c) making sure that the head of the bed is kept at a 90-degree angle d) monitor the weights to be sure that they are resting on a firm surface

77) B - To achieve proper traction, weights need to be free-hanging, with knots kept away from the pulleys. Weights are not to be kept resting on a firm surface. The head of the bed is usually kept low to provide countertraction

1. Mr. Alcasid asks the nurse, "What is osteoarthritis?" Which response from the nurse is correct? a) your bones are inflamed b) your weight bearing joints are inflamed c) you have inflammation in your joints d) there is shortening of your long bones

1) B - Osteoarthritis, also known as hypertrophic arthritis, osteoarthritis, senescent arthritis and degenerative joint disease is characterized by destruction of the articular cartilage, which becomes opaque, yellow, soft, weak and deteriorated. It is followed by thickening of bone under the cartilage and formation of osteophytes or bone spurs. Unlike RH, osteoarthritis is not a systemic disease and affects only the joint and its surrounding tissue. This disorder commonly occurs in the 50-70 year age group but women are more severely affected. The Signs and Symptoms of Osteoarthritis include: pain - worse with weight bearing, improves with rest may occur with paresthesia joint swelling and enlargement - may be from inflammatory exudates entering joint capsule causing an increase in synovial fluid or from fragments of osteophytes entering synovial cavity decreased ROM - depends on the amount of destroyed cartilage muscular atrophy - from disuse, joint instability and deformity crepitus - must be present on movement of the joint joint stiffness - worse in the morning and after a period of rest and disuse heberden's nodes - bony protuberances occurring on the dorsal surface of the distal interphalangeal joints of the fingers bouchard's nodes - bony protruberances occurring on the proximal interphalangeal joints of fingers coxaarthrosis - pain in the hip on weight bearing with pain progressing to include the groin and medial knee pain and limited range of motion varus (bowlegs) or valgus (knock kneed)

15. A client is brought to the emergency room with compound femur fracture. What is the first action the emergency room nurse should do? a) cover the open wound b) check the clients blood pressure c) assess the client's neurologic status d) prepare the client for X-ray

15) B - compound fracture of the femur may cause severe internal bleeding. Internal bleeding is characterized by hypotension.

16. A 3-year old in Bryant's traction is with foot foam. You found the child pulling out the foot foam. What is your most appropriate nursing action? a) remove the foot foam and assess the area b) reapply the foot foam at once c) call another nurse to maintain traction as you reapply the foot foam d) tell the child to stop removing the foot foam

16) C - maintain the traction as the foot foam is reapplied.

17. How do you position a client with left hip fracture in Buck's traction? a) head of bed raised at 45 degree angle b) left calf on pillow from knee to ankle c) position the left on affected side with pillows between legs d) position the left in the center of the bed with the leg extended

17) B - elevate the leg with pillow to relieve pressure from the heel of the foot and to improve the effectiveness of the countertraction.

2. Which of the following guidelines should a nurse include in the teaching plan for a patient who has osteoarthritis? a) achieve ideal body weight b) increase daily calcium intake to 1500 mg c) maintain a high fiber diet d) sleep at least 10 hours each day

2) A - the primary cause of arthritis is not yet known but it is often-associated with obesity, aging, trauma, fractures, and infections. Osteoarthritis is a wear and tear disease of the joints. The more pressure it takes the more severe and the faster is the progression of the disease. Thus, one of the important aspects of management if the patient is obese is to lose weight to lessen the pressure on the joints

34. The client will go electromyography (EMG). Which of the following information should be given when preparing the client for this procedure? a) a contrast medium will be injected into your vein b) you will be placed in a tunnel-like device c) electrode needles will be inserted into your muscles d) scalp electrodes will be applied and graphical recording of electrical activities of your brain will be done

34) C - in EMG, electrode needles will be inserted into the muscles. There will be mild discomfort.

35. X-rays confirm that a patient has a fractured femur. While the patient is in balanced skeletal traction, which of these measures is important? a) adjusting the weights when moving him up in bed b) supporting his affected leg in plantar flexion c) raising him up in bed whenever he slips down d) maintaining him in semi-fowler's position

35) C - raising the patient with traction, up in bed whenever he slips down maintains efficiency of the traction.

37. The client with cervical spinal cord injury is on halo-vest traction. Which of the following emergency equipment is most important to keep readily available at the bedside? a) small wrench b) suction apparatus c) ambu bag d) tracheostomy tray

37) A - the small wrench taped over the vest will be used for untightening the screws of the traction if CPR needs to be done to the client with halo-vest traction.

38. The client had undergone total hip replacement. Which of the following crutch-walking gaits is most appropriate for the client? a) four-point gait b) two-point gait c) swing-to gait d) three-point gait

38) D - three point gait is the most appropriate crutch gait for the client who had undergone total hip replacement. It is a non-weight bearing crutch gait.

41. A nurse is working with a nursing assistant on an orthopedic unit. The nurse observes the nursing assistant caring for a client after a left total hip replacement. The nurse will intervene if which of the following is observed? a) the nursing assistant stoops by bending at the hips and knees to pick up an object that the client dropped on the floor b) the nursing assistant keeps the client's bed in the low position when administering the bath c) the client is positioned with leg abducted slightly d) the head of the bed is elevated 30 degrees

41) B - during administration of bath, the nursing assistant should raise the bed to waist level to prevent bending and stooping. This prevents muscle strain and back injury.

42. A nurse has conducted preoperative teaching for a client scheduled for surgery in 1 week. The client has a history of arthritis and has been taking acetylsalicylic acid (aspirin). The nurse determines that the client needs additional teaching if the client states: a) aspirin can cause bleeding after surgery b) aspirin can cause my ability to clot blood to abnormal c) I need to discontinue the aspirin 48 hours before the scheduled surgery d) I need to continue to take aspirin until the day of surgery

42) D - anticoagulants alter normal clotting factors and increase the risk of bleeding after surgery. Aspirin has properties that can alter the clotting mechanism and should be discontinued at least 48 hours before surgery. Options A, B, and C are accurate client statements.

43. A 4-year old sustains a fall at home and is brought to the emergency room by the mother. After an x-ray examination, the child is determined to have a fractured arm and plaster cast is applied. The nurse provides instructions to the mother regarding care for the child's cast. Which statement by the mother indicates a need for further instructions? a) the cast may feel warm as the cast dries b) I can use lotion or powder around the cast edges to relieve itching c) a small amount of white shoe polish can touch up a soiled white cast d) if the cast becomes wet, a blow drier set on the cool setting may be used to dry the cast

43) B - The mother needs to be instructed not to use lotion or powders on the skin around the cast edges or inside the cast. Lotions or powders can become sticky or caked and cause skin irritation. Options A, C, and D are appropriate instructions.

45. A 1-month old infant is seen in a clinic and is diagnosed with developmental dysplasia of the hip (DDH). The nurse assesses the infant, knowing that which of the following findings would be noted in this condition? a) limited range of motion in the affected hip b) an apparent lengthened femur on the affected side c) asymmetrical adduction of hte affected hip when the infant is placed supine with the knees and hips flexed d) symmetry of the gluteal skinfolds when the infant is placed prone and the legs are extended against the examining table

45) A - In DDH, the head of the femur is seated improperly in the acetabulum or hip socket of the pelvis. Asymmetrical abduction of the affected hip, when the child is placed supine with the knees and hips flexed, would be an assessment finding in DDH in infants beyond the newborn period. Other findings include an apparent short femur on the affected side, asymmetry of the gluteal skinfolds, and limited range of motion in the affected extremity.

46. A client is treated in physician's office for a sprained ankle after a fall. Radiographic examination has ruled out a fracture. Before sending the client home, the nurse plans to teach the client to avoid which of the following in the next 24 hours? a) resting the foot b) applying a heating pad c) applying an elastic compression bandage d) elevating the ankle on a pillow while sitting or lying down

46) B - Soft tissue injuries such as sprains are treated by RICE (rest, ice, compression, and elevation) for the first 24 hours after the injury. Ice is applied intermittently for 20 to 30 minutes at a time. Heat is not used in the first 24 hours because it could increase venous congestion, which would increase edema and pain.

48. A nurse has given instructions to a client returning home after knee arthroscopy. The nurse determines that the client understands the instructions if the client states that he or she will: a) resume regular exercise the following day b) stay off the leg entirely for the rest of the day c) report fever or site inflammation to the physician d) refrain from eating food for the remainder of the day

48) C - After arthroscopy, the client usually can walk carefully on the leg once sensation has returned. The client is instructed to avoid strenuous exercise for at least a few days. The client may resume the usual diet. Signs and symptoms of infection should be reported to the physician.

49. A client with possible rib fracture has never had a chest radiograph. The nurse would plan to tell the client which of the following items about the procedure? a) the x-rays stimulate a small amount of pain b) removal of jewelry and any other metal objects is necessary c) the client will be asked to breathe in and out as the x-ray is taken d) the x-ray technologist will stand next to the client during the procedure

49) B - A radiograph is a photographic image of part of the body on a special film, which is used to diagnose a wide variety of conditions. Radiography itself is painless; any discomfort would arise from repositioning a painful part for filming. The nurse may want to premedicate a client who is at risk for pain. Any radiopaque objects such as jewelry or other metal must be removed. The client is asked to breathe in deeply and then hold the breath while the chest radiograph is taken. To minimize risk of radiation exposure, the x-ray technologist stands in a separate area protected by a lead wall. The client also wears a lead shield over his or her gonads.

50. A nurse is one of several persons who witness a vehicle hit a pedestrian at fairly low speed on a small street. The person is dazed and tries to get up. The leg appears fractured. The nurse would plna to: a) try to reduce the fracture manually b) assist the person to get up and walk to the sidewalk c) leave the person for a few moments to call an ambulance d) stay with the person and encourage the person to remain still

50) D - With a suspected fracture, the client is not moved unless it is dangerous to remain in that spot. The nurse should remain with the client and have someone else call for emergency help. A fracture is not reduced at the scene. Before the client is moved, the site of fracture is immobilized to prevent further injury.

52. A nurse has given a client with a leg cast instructions on cast care at home. The nurse would evaluate that the client needs further instruction if the client makes which of the following statements? a) I should avoid walking on wet, slippery floors b) I'm not supposed to scratch the skin underneath the cast c) it's okay to wipe dirt off the top of the cast with a damp cloth d) if the cast gets wet, I can dry it with a hair dryer turned to the warmest setting

52) D - Client instructions should include avoiding walking on wet slippery floors to prevent falls. Surface soil on a cast can be removed with a damp cloth. If the cast gets wet, it can be dried with a hair dryer set to a cool setting to prevent skin breakdown. If the skin under the cast itches, cool air from a hair dryer may be used to relieve it. The client should never scratch under a cast because of the risk of skin breakdown and ulcer formation.

54. A client returns to the nursing unit following the application of skeletal leg traction. Upon assessment, the nurse notes a small amount of bleeding around the pin insertion sites. The nurse should take which action? a) notify the surgeon b) recheck the site in 1 hour c) check the client's vital signs d) place a small pressure dressing at the bleeding site

54) D - Following pin insertion for skeletal traction, a small amount of bleeding is expected. This can be controlled with small pressure dressings; however, bleeding that continues for more than 24 hours should be brought to the surgeon's attention. It is not necessary to notify the surgeon immediately. Rechecking the site in 1 hour delays necessary intervention. Although vital signs may be checked in the immediate post-operative period, this action is unrelated to the small amount of bleeding.

55. A nurse is evaluating the pin sites of a client in skeletal traction. The nurse would be least concerned with which of the following findings? a) inflammation b) serous drainage c) pain at a pin site d) purulent drainage

55) B - A small amount of serous oozing is expected at pin insertion sites. Signs of infection such as inflammation, purulent drainage, and pain at the pin site are not expected findings and should be reported to the physician.

56. A client with a fractured right ankle has a short leg cast applied in the emergency department. During discharge teaching, the nurse provides which information to the client to prevent complications? a) trim the rough edges of the cast after it is dry b) weigh-bearing on the right leg is allowed once the cast feels dry c) expect burning and tingling sensations under the cast for 3 to 4 days d) keep the right ankle elevated above the heart level with pillows for 24 hours

56) D - Leg elevation is important to increase venous return and decrease edema, which can cause compartment syndrome, a major complication of fractures and casting. Weight-bearing on a fractured extremity is prescribed by the physician during follow-up examination, after radiographs are obtained. Additionally, a walking heel or cast shoe may be added to the cast if the client is allowed to bear weight and walk on the affected leg. Although the client may feel heat after the cast is applied, burning and/or tingling sensations indicate nerve damage or ischemia and are not expected. These complaints should be reported immediately. Option 1 is incorrect. The client and/or family may be taught how to "petal" the cast to prevent skin irritation and breakdown, but rough edges, if trimmed, can fall into the cast and cause a break in skin integrity.

57. An older adult female client with a fractured left tibia has a long leg cast and is using crutches to ambulate. In caring for the client, the nurse assesses for which sign or symptom that indicates a complication associated with crutch walking? a) left leg discomfort b) weak biceps brachii c) triceps muscle spasms d) forearm muscle weakness

57) D - Forearm muscle weakness is a sign of radial nerve injury caused by crutch pressure on the axillae. When a client lacks upper body strength, especially in the flexor and extensor muscles of the arms, he or she frequently allows weight to rest on the axillae and on the crutch pads instead of using the arms for support while ambulating with crutches. Leg discomfort is expected as a result of the injury. Triceps muscle spasms may occur as a result of increased muscle use but is not a complication of crutch walking. Weak biceps brachii is a common physical assessment finding in older adults and is not a complication of crutch walking.

58. A nurse is caring for a client with Buck's traction and is monitoring the client for complications of the traction. Which assessment finding indicates a complication? a) weak pedal pulses b) drainage at the pin sites c) complaints of discomfort d) warm toes with brisk capillary refill

58) A - Weak pedal pulses are a sign of vascular compromise, which can be caused by pressure on the tissues of the leg by the elastic bandage or prefabricated boot used to secure this type of traction.

59. A client has fallen and sustained a leg injury. Which question would the nurse ask the cleint to help determine if the injury caused a fracture? a) is the pain a dull ache? b) is the pain sharp and continuous? c) does the discomfort feel like a cramp? d) does the pain feel like the muscle was stretched?

59) B - Fracture pain is generally described as sharp, continuous, and increasing in frequency. Bone pain is often described as a dull, deep ache. Strains result from trauma to a muscle body or to the attachment of a tendon from overstretching or overextension. Muscle injury is often described as an aching or cramping pain, or soreness.

61. A nurse is performing pin site care on a client in skeletal traction. Which finding would the nurse expect to note when assessing the pin sites? a) loose pin sites b) clear drainage from the pin sites c) purulent drainage from the pin sites d) redness and swelling around the pin sites

61) B - A small amount of clear drainage ("weeping") may be expected after cleaning and removing crusting around the pin sites. Redness and swelling around the pin sites and purulent drainage may be indicative of an infection. Pins should not be loose, and, if this is noted, the physician should be notified.

62. A nurse is caring for a client who has been placed in Buck's extension traction while awaiting surgical repair of a fractured femur. The nurse prepares to perform a complete neurovascular assessment of the affected extremity and plans to assess: a) vital signs and bilateral lung sounds b) warmth of the skin and the temperature in the affected extremity c) pain level and for the presence of edema in the affected extremity d) color, sensation, movement, capillary refill, and pulse of the affected extremity

62) D - A complete neurovascular assessment of an extremity includes color, sensation, movement, capillary refill, and pulse of the affected extremity.

63. A client in the emergency department has a cast applied. The client arrives at the nursing unit, and the nurse prepares to transfer the client into the bed by: a) placing ice on top of the cast b) supporting the cast with the fingertips only c) asking the client to support the cast during transfer d) using the palms of the hands and soft pillows to support the cast

63) D - The palms or the flat surface of the extended fingers should be used when moving a wet cast to prevent indentations. Pillows are used to support the curves of the cast to prevent cracking or flattening of the cast from the weight of the body. Half-full bags of ice may be placed next to the cast to prevent swelling, but this action would be performed after the client is placed in bed. Asking the client to support the cast during transfer is inappropriate.

65. The nurse is caring for a client who develops compartment syndrome from a severely fractured arm. The client asks the nurse how this can happen. The nurse's response is based on the understanding that: a) A bone fragment has injured the nerve supply in the area b) an injured artery causes impaired arterial perfusion through the compartment c) bleeding and swelling cause increased pressure in an area that cannot expand d) the fascia expands with injury, causing pressure on underlying nerves and muscles

65) C - Compartment syndrome is caused by bleeding and swelling within a compartment, which is lined by fascia that does not expand. The bleeding and swelling place pressure on the nerves, muscles, and blood vessels in the compartment, triggering the symptoms.

66. A client has undergone fasciotomy to treat compartment syndrome of the leg. The nurse prepares to provide which type of wound care to the fasciotomy site? a) dry sterile dressings b) hydrocolloid dressings c) wet sterile saline dressings d) one-half strength betadine dressings

66) C - The fasciotomy site is not sutured but is left open to relieve pressure and edema. The site is covered with wet sterile saline dressings. After 3 to 5 days, when perfusion is adequate and edema subsides, the wound is debrided and closed. A hydrocolloid dressing is not indicated for use with clean, open incisions. The incision is clean, not dirty, so there should be no reason to require Betadine. Additionally, Betadine can be irritating to normal tissues.

67. An older client admitted to the hospital with a hip fracture is placed in Buck's extension traction. The nurse plans to frequently monitor which specimen item? a) temperature b) mental state c) neurovascular status d) range of motion ability

67) C - The neurovascular status of the extremity of the client in Buck's extension traction must be assessed frequently. Older clients are especially at risk for neurovascular compromise because many older clients already have disorders that affect the peripheral vascular system. Although the client's temperature is monitored, it is not specific to the use of Buck's extension traction. Although clients in some types of traction do become depressed after a few days or weeks, Buck's extension traction is usually used preoperatively, which typically involves a few hours or 1 to 2 days, at the most. Range of motion of the involved leg is contraindicated in hip fractures.

68. Buck's extension traction is applied to an older client following a hip fracture. The nurse explains to the client that this type of traction is: a) traction involving the use of a cast b) skeletal traction involving the use of surgically inserted pins c) circumferential traction involving the use of a belt around the body d) skin traction involving the use of traction attached to the skin and soft tissues

68) D - Buck's extension traction is a form of skin traction and involves the use of a belt or boot that is attached to the skin and soft tissues. The purpose of this type of traction is to decrease painful muscle spasms that accompany fractures. The weight that is used as a pulling force is limited (usually 5 to 10 pounds) to prevent injury to the skin. Options A, B, and C are incorrect descriptions.

69. A client has Buck's extension traction applied to the right leg. The nurse plans which of the following interventions to prevent complications from the device? a) provide pin care once a shift b) massage the skin of the right leg with lotion every 8 hours c) inspect the skin on the right leg at least once every 8 hours d) release the weights on the right leg for range of motion exercises daily

69) C Buck's extension traction is a type of skin traction. The nurse inspects the skin of the limb in traction at least once every 8 hours for irritation or inflammation. Massaging the skin with lotion is not indicated. The nurse never releases the weights of traction unless specifically ordered by the physician. There are no pins to care for with skin traction.

70. The nurse is caring for a client with a newly applied leg cast. The nurse prevents the development of compartment syndrome by: a) elevating the limb and applying ice to the affected leg b) elevating the limb and covering the limb with bath blankets c) keeping the leg horizontal and applying ice to the affected leg d) placing the leg in a slight dependent position and applying ice

70) A - Compartment syndrome is prevented by controlling edema. This is achieved most optimally with the use of elevation and the application of ice. The use of bath blankets or a dependent or horizontal leg position will not prevent this syndrome.

71. A client has sustained a closed fracture and has just has a cast applied to the affected arm. The client is complaining of intense pain. The nurse has elevated the limb, applied an ice bag, and administered an analgesic, which has provided very little pain relief. The nurse interprets that this pain may be caused by: a) infection under the cast b) the anxiety of the client c) impaired tissue perfusion d) the newness of the fracture

71) C - Most pain associated with fractures can be minimized with rest, elevation, application of cold, and administration of analgesics. Pain that is not relieved from these measures should be reported to the physician, because it may be caused by impaired tissue perfusion, tissue breakdown, or necrosis. Because this is a new closed fracture and cast, infection would not have had time to set in.

72. The client with a fractured femur experiences sudden dyspnea. A set of arterial blood gases reveal the following: pH is 7.32, PaCO2 is 43, PaO2 is 58, and HCO3 is 20. Which of the following components of the ABG results supports the nurse's suspicion of fat embolus? a) pH b) PaO2 c) HCO3 d) PaCO2

72) B - A key feature of fat embolism is a significant degree of hypoxemia with a Pao2 often less than 60 mm Hg. Other features that distinguish fat embolism from pulmonary embolism are an elevated temperature and the presence of fat in the blood with fat embolus.

73. The rehabilitation nurse is providing home care instruction for a client being discharged after above-the-knee amputation of the right lower limb with a fitted prosthesis. The nurse determines the client requires further teaching if the client makes which of the following statements? a) I will elevate the residual limb on a pillow b) I will change the residual limb sock everyday c) I will check the residual limb for skin irritation daily d) I will notify my prosthesis if my residual limb sock becomes stretched or ill-fitting

73) A - Clients must avoid elevation of the residual limb to prevent flexion contractures of the right hip. Additionally, sitting in a chair should be limited to 1-hour intervals to avoid the same. If there is no contraindication, clients should lie in the prone position three to four times a day to promote hip extension. Limb socks should be removed daily, laundered in mild soap, and replaced with a clean sock. When the sock is removed, the residual limb should be inspected for erythema and excoriation. As the edema resolves, the residual limb shrinks and the sock may not fit properly, leading to skin irritation. The prosthetist should be notified of the ill-fitting sock.

74. A client arrives at the clinic complaining of knee pain. On assessment the nurse notes that the knee area is swollen. The nurse interprets that the client's signs and symptoms likely indicate: a) osteoporosis b) a recent injury c) rheumatoid arthritis d) degenerative joint disease

74) B - Pain and swelling are associated with musculoskeletal inflammation, infection, or a recent injury. Degenerative joint disease, osteoporosis, and rheumatoid arthritis may be accompanied by pain, but swelling may or may not be present.

75. A client seeks treatment in the emergency department for a lower leg injury. There is visible deformity to the lower aspect of the leg, and the injured leg appears shorter than the other leg. The area is painful, swollen, and beginning to become ecchymotic. The nurse interprets that this client has experienced a: a) strain b) sprain c) fracture d) contusion

75) C - Typical signs and symptoms of fracture include pain, loss of function in the area, deformity, shortening of the extremity, crepitus, swelling, and ecchymosis. Not all fractures lead to the development of every sign. A strain results from a pulling force on the muscle. Symptoms include soreness and pain with muscle use. A sprain is an injury to a ligament caused by a wrenching or twisting motion. Symptoms include pain, swelling, and inability to use the joint or bear weight normally. A contusion results from a blow to soft tissue and causes pain, swelling, and ecchymosis.

78. A client with a possible rib fracture has never had a chest x-ray. The nurse plans to tell the client which of the following about the procedure? a) the x-ray stimulates a small amount of pain b) the client will be asked to breathe in and out continuously during the x-ray c) the x-ray technologist will stand next to the client during the x-ray d) it is necessary to remove jewelry and any other metal objects from the chest area

78) D - An x-ray is a photographic image of a part of the body on a special film, which is used to diagnose a wide variety of conditions. Any radiopaque objects such as jewelry or other metal must be removed from the chest area because they will interfere with the interpretation of the results. The x-ray is painless, and any discomfort would arise from repositioning a painful part for filming. The nurse may premedicate a client, if prescribed, who is at risk for pain. The client is asked to breathe in deeply and then hold the breath while the chest x-ray is taken. To minimize the risk of radiation exposure, the x-ray technologist stands in a separate area protected by a lead wall. The client also wears a lead shield over the reproductive organs.
