Peds Quiz 4 (Ch. 29 & 30)
The nurse is caring for an adolescent with osteosarcoma being admitted to undergo chemotherapy. The adolescent had a right above-the-knee amputation 2 months ago and has been experiencing "phantom limb pain." Which prescribed medication is appropriate to administer to relieve phantom limb pain? a. Amitriptyline (Elavil) b. Hydrocodone (Vicodin) c. Oxycodone (OxyContin) d. Alprazolam (Xanax)
A Amitriptyline (Elavil) has been used successfully to decrease phantom limb pain. Opioids such as Vicodin or OxyContin would not be prescribed for this pain. A benzodiazepine such as Xanax would not be prescribed for this type of pain.
Latex allergy is suspected in a child with spina bifida. Appropriate nursing interventions include which action? a. Avoid using any latex product. b. Use only nonallergenic latex products. c. Administer medication for long-term desensitization. d. Teach family about long-term management of asthma.
A Care must be taken that individuals who are at high risk for latex allergies do not come in direct or secondary contact with products or equipment containing latex at any time during medical treatment. There are no nonallergenic latex products. At this time, desensitization is not an option. The child does not have asthma. The parents must be taught about allergy and the risk of anaphylaxis.
The nurse is conducting a staff in-service on common problems associated with myelomeningocele. Which common problem is associated with this defect? a. Hydrocephalus b. Craniostenosis c. Biliary atresia d. Esophageal atresia
A Hydrocephalus is a frequently associated anomaly in 80% to 90% of children. Craniostenosis is the preterm closing of the cranial sutures and is not associated with myelomeningocele. Biliary and esophageal atresia is not associated with myelomeningocele.
The nurse is planning a staff in-service on childhood spastic cerebral palsy. What characterizes spastic cerebral palsy? a. Hypertonicity and poor control of posture, balance, and coordinated motion b. Athetosis and dystonic movements c. Wide-based gait and poor performance of rapid, repetitive movements d. Tremors and lack of active movement
A Hypertonicity and poor control of posture, balance, and coordinated motion are part of the classification of spastic cerebral palsy. Athetosis and dystonic movements are part of the classification of dyskinetic (athetoid) cerebral palsy. Wide-based gait and poor performance of rapid, repetitive movements are part of the classification of ataxic cerebral palsy. Tremors and lack of active movement may indicate other neurologic disorders.
Which term is used to describe a type of fracture that does not produce a break in the skin? a. Simple b. Compound c. Complicated d. Comminuted
A If a fracture does not produce a break in the skin, it is called a simple, or closed, fracture. A compound, or open, fracture is one with an open wound through which the bone protrudes. A complicated fracture is one in which the bone fragments damage other organs or tissues. A comminuted fracture occurs when small fragments of bone are broken from the fractured shaft and lie in the surrounding tissue. These are rare in children.
A child is upset because when the cast is removed from her leg, the skin surface is caked with desquamated skin and sebaceous secretions. Which should the nurse suggest to remove this material? a. Soak in a bathtub. b. Vigorously scrub leg. c. Apply powder to absorb material. d. Carefully pick material off leg.
A Simple soaking in the bathtub is usually sufficient for the removal of the desquamated skin and sebaceous secretions. It may take several days to eliminate the accumulation completely. The parents and child should be advised not to scrub the leg vigorously or forcibly remove this material because it may cause excoriation and bleeding. Oil or lotion, but not powder, may provide comfort for the child.
The nurse is conducting a staff in-service on casts. Which is an advantage to using a fiberglass cast instead of a plaster of Paris cast? a. Cheaper b. Dries rapidly c. Molds closely to body parts d. Smooth exterior
B A synthetic casting material dries in 5 to 30 minutes as compared with a plaster cast, which takes 10 to 72 hours to dry. Synthetic casts are more expensive and have a rough exterior, which may scratch surfaces. Plaster casts mold closer to body parts.
Which is an appropriate nursing intervention when caring for a child in traction? a. Remove adhesive traction straps daily to prevent skin breakdown. b. Assess for tightness, weakness, or contractures in uninvolved joints and muscles. c. Provide active range-of-motion exercises to affected extremity three times a day. d. Keep the child in one position to maintain good alignment
B Traction places stress on the affected bone, joint, and muscles. The nurse must assess for tightness, weakness, or contractures developing in the uninvolved joints and muscles. The adhesive straps should be released or replaced only when absolutely necessary. Active, passive, or active with resistance exercises should be carried out for the unaffected extremity only. Movement is expected with children. Each time the child moves, the nurse should check to ensure that proper alignment is maintained.
An adolescent with a fractured femur is in Russell's traction. Surgical intervention to correct the fracture is scheduled for the morning. Nursing actions should include which action? a. Maintaining continuous traction until 1 hour before the scheduled surgery b. Maintaining continuous traction and checking position of traction frequently c. Releasing traction every hour to perform skin care d. Releasing traction once every 8 hours to check circulation
B When the muscles are stretched, muscle spasm ceases and permits realignment of the bone ends. The continued maintenance of traction is important during this phase because releasing the traction allows the muscle's normal contracting ability to again cause malpositioning of the bone ends. Continuous traction must be maintained to keep the bone ends in satisfactory realignment. Releasing at any time, either 1 hour before surgery, once every hour for skin care, or once every 8 hours would not keep the fracture in satisfactory alignment.
A school nurse is conducting a staff in-service to other school nurses on idiopathic scoliosis. During which period of child development does idiopathic scoliosis become most noticeable? a. Newborn period b. When child starts to walk c. Preadolescent growth spurt d. Adolescence
C Idiopathic scoliosis is most noticeable during the preadolescent growth spurt. Idiopathic scoliosis is seldom apparent before age 10 years. Diagnosis usually occurs during the preadolescent growth spurt.
The nurse is teaching a family how to care for their infant in a Pavlik harness to treat developmental dysplasia of the hip. Which should be included? a. Apply lotion or powder to minimize skin irritation. b. Remove harness several times a day to prevent contractures. c. Return to clinic every 1 to 2 weeks. d. Place diaper over harness, preferably using a superabsorbent disposable diaper that is relatively thin.
C Infants have a rapid growth pattern. The child needs to be assessed by the practitioner every 1 to 2 weeks for possible adjustments. Lotions and powders should not be used with the harness. The harness should not be removed, except as directed by the practitioner. A thin disposable diaper can be placed under the harness.
A neonate is born with bilateral mild talipes equinovarus (clubfoot). When the parents ask the nurse how this will be corrected, the nurse should give which explanation? a. Traction is tried first. b. Surgical intervention is needed. c. Frequent, serial casting is tried first. d. Children outgrow this condition when they learn to walk.
C Serial casting is begun shortly after birth before discharge from nursery. Successive casts allow for gradual stretching of skin and tight structures on the medial side of the foot. Manipulation and casting of the leg are repeated frequently (every week) to accommodate the rapid growth of early infancy. Serial casting is the preferred treatment. Surgical intervention is done only if serial casting is not successful. Children do not improve without intervention.
The nurse is caring for a 12-year-old child with a left leg below-the-knee amputation (BKA). The child had the surgery 1 week ago. Which intervention should the nurse plan to implement for this child? a. Elevate the left stump on a pillow. b. Place an ice pack on the stump. c. Encourage the child to use an overhead bed trapeze when repositioning. d. Replace the ace wrap covering the stump with a gauze dressing.
C Use of the overhead bed trapeze should be encouraged to begin to build up the arm muscles necessary for walking with crutches. Stump elevation may be used during the first 24 hours, but after this time, the extremity should not be left in this position because contractures in the proximal joint will develop and seriously hamper ambulation. Ice would not be an appropriate intervention and would decrease circulation to the stump. Stump shaping is done postoperatively with special elastic bandaging using a figure-eight bandage, which applies pressure in a cone-shaped fashion. This technique decreases stump edema, controls hemorrhage, and aids in developing desired contours so the child will bear weight on the posterior aspect of the skin flap rather than on the end of the stump. This wrap should not be replaced with a gauze dressing.
The nurse is preparing to admit a newborn with myelomeningocele to the neonatal intensive care nursery. Which describes this newborn's defect? a. Fissure in the spinal column that leaves the meninges and the spinal cord exposed b. Herniation of the brain and meninges through a defect in the skull c. Hernial protrusion of a saclike cyst of meninges with spinal fluid but no neural elements d. Visible defect with an external saclike protrusion containing meninges, spinal fluid, and nerves
D A myelomeningocele is a visible defect with an external saclike protrusion, containing meninges, spinal fluid, and nerves. Rachischisis is a fissure in the spinal column that leaves the meninges and the spinal cord exposed. Encephalocele is a herniation of brain and meninges through a defect in the skull, producing a fluid-filled sac. Meningocele is a hernial protrusion of a saclike cyst of meninges with spinal fluid, but no neural elements.
Which medication is usually tried first when a child is diagnosed with juvenile idiopathic arthritis (JIA)? a. Aspirin b. Corticosteroids c. Cytotoxic drugs such as methotrexate d. Nonsteroidal antiinflammatory drugs (NSAIDs)
D NSAIDs are the first drugs used in JIA. Naproxen, ibuprofen, and tolmetin are approved for use in children. Aspirin, once the drug of choice, has been replaced by the NSAIDs because they have fewer side effects and easier administration schedules. Corticosteroids are used for life-threatening complications, incapacitating arthritis, and uveitis. Methotrexate is a second-line therapy for JIA.
The parents of a child with cerebral palsy ask the nurse whether any drugs can decrease their child's spasticity. The nurse's response should be based on which statement? a. Anticonvulsant medications are sometimes useful for controlling spasticity. b. Medications that would be useful in reducing spasticity are too toxic for use with children. c. Many different medications can be highly effective in controlling spasticity. d. Implantation of a pump to deliver medication into the intrathecal space to decrease spasticity has recently become available.
D Baclofen, given intrathecally, is best suited for children with severe spasticity that interferes with activities of daily living and ambulation. Anticonvulsant medications are used when seizures occur in children with cerebral palsy. The intrathecal route decreases the side effects of the drugs that reduce spasticity. Few medications are currently available for the control of spasticity.
What should be administered to a child with tetanus? a. Nonsteroidal antiinflammatory drugs (NSAIDs) to reduce inflammation. b. Muscle stimulants to counteract muscle weakness. c. Bronchodilators to prevent respiratory complications. d. Tetanus immunoglobulin therapy.
D Tetanus immunoglobulin therapy, to neutralize toxins, is the most specific therapy for tetanus. Tetanus toxin acts at the myoneural junction to produce muscular stiffness and lowers the threshold for reflex excitability. NSAIDs are not routinely used. Sedatives or muscle relaxants are used to help reduce titanic spasm and prevent seizures. Respiratory status is carefully evaluated for any signs of distress because muscle relaxants, opioids, and sedatives that may be prescribed may cause respiratory depression. Bronchodilators would not be used unless specifically indicated.
The nurse uses the palms of the hands when handling a wet cast for which reason? a. To assess dryness of the cast b. To facilitate easy turning c. To keep the patient's limb balanced d. To avoid indenting the cast
D Wet casts should be handled by the palms of the hands, not the fingers, to avoid creating pressure points. Assessing dryness, facilitating easy turning, and keeping the patient's limb balanced are not reasons for using the palms of the hand rather than the fingers when handling a wet cast.
Which can result from the bone demineralization associated with immobility? a. Osteoporosis b. Urinary retention c. Pooling of blood d. Susceptibility to infection
A Bone demineralization leads to a negative calcium balance, osteoporosis, pathologic fractures, extraosseous bone formation, and renal calculi. Urinary retention is secondary to the effect of immobilization on the urinary tract. Pooling of blood is a result of the cardiovascular effects of immobilization. Susceptibility to infection can result from the effects of immobilization on the respiratory and renal systems.
The nurse is teaching a group of nursing students about newborns born with the congenital defect of myelomeningocele. Which common problem is associated with this defect? a. Neurogenic bladder b. Cognitive impairment c. Respiratory compromise d. Cranioschisis
A Myelomeningocele is one of the most common causes of neuropathic (neurogenic) bladder dysfunction among children. Risk of cognitive impairment is minimized through early intervention and management of hydrocephalus. Respiratory compromise is not a common problem in myelomeningocele. Cranioschisis is a skull defect through which various tissues protrude. It is not associated with myelomeningocele.
A 4-year-old child has just been diagnosed with pseudohypertrophic (Duchenne) muscular dystrophy. The management plan should include which action? a. Recommend genetic counseling. b. Explain that the disease is easily treated. c. Suggest ways to limit use of muscles. d. Assist family in finding a nursing facility to provide child's care.
A Pseudohypertrophic (Duchenne) muscular dystrophy is inherited as an X-linked recessive gene. Genetic counseling is recommended for parents, female siblings, maternal aunts, and their female offspring. No effective treatment exists at this time for childhood muscular dystrophy. Maintaining optimal function of all muscles for as long as possible is the primary goal. It has been found that children who remain as active as possible are able to avoid wheelchair confinement for a longer time. Assisting the family in finding a nursing facility to provide the child's care is inappropriate at the time of diagnosis. When the child becomes increasingly incapacitated, the family may consider home-based care, a skilled nursing facility, or respite care to provide the necessary care.
A young girl has just injured her ankle at school. In addition to calling the child's parents, what is the most appropriate immediate action by the school nurse? a. Apply ice. b. Observe for edema and discoloration. c. Encourage child to assume a position of comfort. d. Obtain parental permission for administration of acetaminophen or aspirin.
A Soft-tissue injuries should be iced immediately. In addition to ice, the extremity should be rested, be elevated, and have compression applied. Observing for edema and discoloration, encouraging the child to assume a position of comfort, and obtaining parental permission for administration of acetaminophen or aspirin are not immediate priorities. The application of ice can reduce the severity of the injury.
The nurse is preparing an adolescent with scoliosis for a spinal surgical instrumentation placement procedure. Which consideration should the nurse include? a. A chest tube and urinary catheter may be required. b. Ambulation will not be allowed for up to 3 months. c. Surgery eliminates the need for casting and bracing. d. Discomfort can be controlled with nonpharmacologic methods.
A Surgical spinal instrumentation is a surgical procedure. A chest tube and urinary catheterization may be required. Ambulation is allowed as soon as possible. Depending on the instrumentation used, most patients walk by the second or third postoperative day. Casting and bracing are required postoperatively. The child usually has considerable pain for the first few days after surgery. Intravenous opioids should be administered on a regular basis.
Four-year-old David is placed in Buck extension traction for Legg-Calvé-Perthes disease. He is crying with pain as the nurse assesses that the skin of his right foot is pale with an absence of pulse. Which action should the nurse take first? a. Notify the practitioner of the changes noted. b. Give the child medication to relieve the pain. c. Reposition the child and notify physician. d. Chart the observations and check the extremity again in 15 minutes.
A The absence of a pulse and change in color of the foot must be reported immediately for evaluation by the practitioner. Pain medication should be given after the practitioner is notified. Legg-Calvé-Perthes disease is an emergency condition; immediate reporting is indicated. The findings should be documented with ongoing assessment.
The nurse should monitor for which effect on the cardiovascular system when a child is immobilized? a. Venous stasis b. Increased vasopressor mechanism c. Normal distribution of blood volume d. Increased efficiency of orthostatic neurovascular reflexes
A The physiologic effects of immobilization, as a result of decreased muscle contraction, include venous stasis. This can lead to pulmonary emboli or thrombi. A decreased vasopressor mechanism results in orthostatic hypotension, syncope, hypotension, decreased cerebral blood flow, and tachycardia. An altered distribution of blood volume is found with decreased cardiac workload and exercise tolerance. Immobilization causes a decreased efficiency of orthostatic neurovascular reflexes with an inability to adapt readily to the upright position and with pooling of blood in the extremities in the upright position.
The nurse is caring for an infant with myelomeningocele scheduled for surgical closure in the morning. Which intervention should the nurse plan for the care of the myelomeningocele sac? a. Open to air b. Covered with a sterile, moist, nonadherent dressing c. Reinforcement of the original dressing if drainage noted d. A diaper secured over the dressing
B Before surgical closure, the myelomeningocele is prevented from drying by the application of a sterile, moist, nonadherent dressing over the defect. The moistening solution is usually sterile normal saline. Dressings are changed frequently (every 2 to 4 hours), and the sac is closely inspected for leaks, abrasions, irritation, and any signs of infection. The sac must be carefully cleansed if it becomes soiled or contaminated. The original dressing would not be reinforced but changed as needed. A diaper is not placed over the dressing because stool contamination can occur.
Kristin, age 10 years, sustained a fracture in the epiphyseal plate of her right fibula when she fell off of a tree. When discussing this injury with her parents, the nurse should consider which statement? a. Healing is usually delayed in this type of fracture. b. Growth can be affected by this type of fracture. c. This is an unusual fracture site in young children. d. This type of fracture is inconsistent with a fall.
B Detection of epiphyseal injuries is sometimes difficult, but fractures involving the epiphysis or epiphyseal plate present special problems in determining whether bone growth will be affected. Healing of epiphyseal injuries is usually prompt. The epiphysis is the weakest point of the long bones. This is a frequent site of damage during trauma.
The nurse is caring for a preschool child immobilized by a spica cast. Which effect on metabolism should the nurse monitor on this child related to the immobilized status? a. Hypocalcemia b. Decreased metabolic rate c. Positive nitrogen balance d. Increased production of stress hormones
B Immobilization causes a decreased metabolic rate with slowing of all systems and a decreased food intake. Immobilization leads to hypercalcemia and causes a negative nitrogen balance secondary to muscle atrophy. A decreased production of stress hormones occurs with decreased physical and emotional coping capacity.
The nurse is caring for a neonate born with a myelomeningocele. Surgery to repair the defect is scheduled the next day. Which describes the most appropriate way to position and feed this neonate? a. Prone and tube-fed b. Prone, head turned to side, and nipple-fed c. Supine in an infant carrier and nipple-fed d. Supine, with defect supported with rolled blankets, and nipple-fed
B In the prone position, feeding is a problem. The infant's head is turned to one side for feeding. If the child is able to nipple-feed, tube feeding is not needed. Before surgery, the infant is kept in the prone position to minimize tension on the sac and risk of trauma.
How much folic acid is recommended for women of childbearing age? a. 1.0 mg b. 0.4 mg c. 1.5 mg d. 2.0 mg
B It has been estimated that a daily intake of 0.4 mg of folic acid in women of childbearing age will prevent 50% to 70% of cases of neural tube defects; 1.0 mg is too low a dose; 1.5 to 2.0 mg are not the recommended dosages of folic acid.
The nurse is admitting a school-age child with suspected Guillain-Barré syndrome (GBS). Which is a priority in the care for this child? a. Monitoring intake and output b. Assessing respiratory efforts c. Placing on a telemetry monitor d. Obtaining laboratory studies
B Treatment of GBS is primarily supportive. In the acute phase, patients are hospitalized because respiratory and pharyngeal involvement may require assisted ventilation, sometimes with a temporary tracheotomy. Treatment modalities include aggressive ventilatory support in the event of respiratory compromise, intravenous (IV) administration of immunoglobulin (IVIG), and sometimes steroids; plasmapheresis and immunosuppressive drugs may also be used. Intake and output, telemetry monitoring, and obtaining laboratory studies may be part of the plan of care but are not the priority.
A child steps on a nail and sustains a puncture wound of the foot. Which is the most appropriate method for cleansing this wound? a. Wash wound thoroughly with chlorhexidine. b. Wash wound thoroughly with povidone-iodine. c. Soak foot in warm water and soap. d. Soak foot in solution of 50% hydrogen peroxide and 50% water.
C Puncture wounds should be cleansed by soaking the foot in warm water and soap. Chlorhexidine, hydrogen peroxide, and povidone-iodine should not be used because they have a cytotoxic effect on healthy cells and minimal effect on controlling infection.
Which type of traction uses skin traction on the lower leg and a padded sling under the knee? a. Dunlop b. Bryant c. Russell d. Buck extension
C Russell traction uses skin traction on the lower leg and a padded sling under the knee. The combination of longitudinal and perpendicular traction allows realignment of the lower extremity and immobilizes the hips and knees in a flexed position. Dunlop traction is an upper-extremity traction used for fractures of the humerus. Bryant traction is skin traction with the legs flexed at a 90-degree angle at the hip. Buck extension traction is a type of skin traction with the legs in an extended position. It is used primarily for short-term immobilization, preoperatively with dislocated hips, for correcting contractures, or for bone deformities such as Legg-Calvé-Perthes disease.
A home care nurse is caring for an adolescent with a T1 spinal cord injury. The adolescent suddenly becomes flushed, hypertensive, and diaphoretic. Which intervention should the nurse perform first? a. Place the adolescent in a flat right side-lying position. b. Place a cool washcloth on the adolescent's forehead and continue to monitor the blood pressure. c. Implement a standing prescription to empty the bladder with a sterile in and out Foley catheter. d. Take a full set of vital signs and notify the health care provider.
C The adolescent is experiencing an autonomic dysreflexia episode. The paralytic nature of autonomic function is replaced by autonomic dysreflexia, especially when the lesions are above the mid-thoracic level. This autonomic phenomenon is caused by visceral distention or irritation, particularly of the bowel or bladder. Sensory impulses are triggered and travel to the cord lesion, where they are blocked, which causes activation of sympathetic reflex action with disturbed central inhibitory control. Excessive sympathetic activity is manifested by a flushing face, sweating forehead, pupillary constriction, marked hypertension, headache, and bradycardia. The precipitating stimulus may be merely a full bladder or rectum or other internal or external sensory input. It can be a catastrophic event unless the irritation is relieved. Placing a cool washcloth on the adolescent's forehead, continuing to monitor blood pressure and vital signs, and notifying the health care provider would not reverse the sympathetic reflex situation.
Which clinical manifestations in an infant would be suggestive of spinal muscular atrophy (Werdnig-Hoffmann disease)? a. Hyperactive deep tendon reflexes b. Hypertonicity c. Lying in the frog position d. Motor deficits on one side of body
C The infant lies in the frog position with the legs externally rotated, abducted, and flexed at the knees. The deep tendon reflexes are absent. The child has hypotonia and inactivity as the most prominent features. The motor deficits are bilateral.
The nurse is caring for a school-age child diagnosed with juvenile idiopathic arthritis (JIA). Which intervention should be a priority? a. Apply ice packs to relieve stiffness and pain. b. Administer acetaminophen to reduce inflammation. c. Teach the child and family correct administration of medications. d. Encourage range-of-motion exercises during periods of inflammation.
C The management of JIA is primarily pharmacologic. The family should be instructed regarding administration of medications and the value of a regular schedule of administration to maintain a satisfactory blood level in the body. They need to know that NSAIDs should not be given on an empty stomach and to be alert for signs of toxicity. Warm moist heat is best for relieving stiffness and pain. Acetaminophen does not have antiinflammatory effects. Range-of-motion exercises should not be done during periods of inflammation.
A nurse is conducting discharge teaching for parents of an infant with osteogenesis imperfecta (OI). Further teaching is indicated if the parents make which statement? a. "We will be very careful handling the baby." b. "We will lift the baby by the buttocks when diapering." c. "We're glad there is a cure for this disorder." d. "We will schedule follow-up appointments as instructed."
C The treatment for OI is primarily supportive. Although patients and families are optimistic about new research advances, there is no cure. The use of bisphosphonate therapy with IV pamidronate to promote increased bone density and prevent fractures has become standard therapy for many children with OI; however, long bones are weakened by prolonged treatment. Infants and children with this disorder require careful handling to prevent fractures. They must be supported when they are being turned, positioned, moved, and held. Even changing a diaper may cause a fracture in severely affected infants. These children should never be held by the ankles when being diapered but should be gently lifted by the buttocks or supported with pillows. Follow-up appointments for treatment with bisphosphonate can be expected.
The nurse is reviewing prenatal vitamin supplements with an expectant client. Which supplement should be included in the teaching? a. Vitamin A throughout pregnancy b. Multivitamin preparations as soon as pregnancy is suspected c. Folic acid for all women of childbearing age d. Folic acid during the first and second trimesters of pregnancy
C The widespread use of folic acid among women of childbearing age has decreased the incidence of spina bifida significantly. Vitamin A is not related to the prevention of spina bifida. Folic acid supplementation is recommended for the preconception period and during the pregnancy. Only 42% of women actually follow these guidelines.
The nurse is admitting a child with Werdnig-Hoffmann disease (spinal muscular atrophy type 1). Which signs and symptoms are associated with this disease? a. Spinal muscular atrophy b. Neural atrophy of muscles c. Progressive weakness and wasting of skeletal muscle d. Pseudohypertrophy of certain muscle groups
C Werdnig-Hoffmann disease (spinal muscular atrophy type 1) is the most common paralytic form of floppy infant syndrome (congenital hypotonia). It is characterized by progressive weakness and wasting of skeletal muscle caused by degeneration of anterior horn cells. Kugelberg-Welander disease is a juvenile spinal muscular atrophy with a later onset. Charcot-Marie-Tooth disease is a form of progressive neural atrophy of muscles supplied by the peroneal nerves. Progressive weakness is found of the distal muscles of the arms and feet. Duchenne muscular dystrophy is characterized by muscles, especially in the calves, thighs, and upper arms, which become enlarged from fatty infiltration and feel unusually firm or woody on palpation. The term pseudohypertrophy is derived from this muscular enlargement.
Which is a type of skin traction with the legs in an extended position? a. Dunlop b. Bryant c. Russell d. Buck extension
D Buck extension traction is a type of skin traction with the legs in an extended position. It is used primarily for short-term immobilization, preoperatively with dislocated hips, for correcting contractures, or for bone deformities such as Legg-Calvé-Perthes disease. Dunlop traction is an upper-extremity traction used for fractures of the humerus. Bryant traction is skin traction with the legs flexed at a 90-degree angle at the hip. Russell traction uses skin traction on the lower leg and a padded sling under the knee. The combination of longitudinal and perpendicular traction allows realignment of the lower extremity and immobilizes the hips and knees in a flexed position.
The nurse is conducting reflex testing on infants at a well-child clinic. Which reflex finding should be reported as abnormal and considered as a possible sign of cerebral palsy? a. Tonic neck reflex at 5 months of age b. Absent Moro reflex at 8 months of age c. Moro reflex at 3 months of age d. Extensor reflex at 7 months of age
D Establishing a diagnosis of cerebral palsy (CP) may be confirmed with the persistence of primitive reflexes: (1) either the asymmetric tonic neck reflex or persistent Moro reflex (beyond 4 months of age) and (2) the crossed extensor reflex. The tonic neck reflex normally disappears between 4 and 6 months of age. The crossed extensor reflex, which normally disappears by 4 months, is elicited by applying a noxious stimulus to the sole of one foot with the knee extended. Normally, the contralateral foot responds with extensor, abduction, and then adduction movements. The possibility of CP is suggested if these reflexes occur after 4 months.
Which should cause a nurse to suspect that an infection has developed under a cast? a. Complaint of paresthesia b. Cold toes c. Increased respirations d. "Hot spots" felt on cast surface
D If hot spots are felt on the cast surface, they usually indicate infection beneath the area. This should be reported so that a window can be made in the cast to observe the site. The five Ps of ischemia from a vascular injury are pain, pallor, pulselessness, paresthesia, and paralysis. Paresthesia is an indication of vascular injury, not infection. Cold toes may be indicative of too tight a cast and need further evaluation. Increased respirations may be indicative of a respiratory tract infection or pulmonary emboli. This should be reported, and child should be evaluated.
The nurse is taking care of an adolescent diagnosed with kyphosis. Which describes this condition? a. Lateral curvature of the spine b. Immobility of the shoulder joint c. Exaggerated concave lumbar curvature of the spine d. Increased convex angulation in the curve of the thoracic spine
D Kyphosis is an abnormally increased convex angulation in the curve of the thoracic spine. Scoliosis is a complex spinal deformity usually involving lateral curvature, spinal rotation causing rib asymmetry, and thoracic hypokyphosis. Ankylosis is the immobility of a joint. Lordosis is an exaggerated concave lumbar curvature of the spine.
A 4-year-old child is newly diagnosed with Legg-Calvé-Perthes disease. Nursing considerations should include which action? a. Encouraging normal activity for as long as is possible b. Explaining the cause of the disease to the child and family c. Preparing the child and family for long-term, permanent disabilities d. Teaching the family the care and management of the corrective appliance
D The family needs to learn the purpose, function, application, and care of the corrective device and the importance of compliance to achieve the desired outcome. The initial therapy is rest and non-weight bearing, which helps reduce inflammation and restore motion. Legg-Calvé-Perthes is a disease with an unknown etiology. A disturbance of circulation to the femoral capital epiphysis produces an ischemic aseptic necrosis of the femoral head. The disease is self-limiting, but the ultimate outcome of therapy depends on early and efficient therapy and the child's age at onset.
The nurse is conducting teaching to parents of a 7-year-old child who fractured an arm and is being discharged with a cast. Which instruction should be included in the teaching? a. Swelling of the fingers is to be expected for the next 48 hours. b. Immobilize the shoulder to decrease pain in the arm. c. Allow the affected limb to hang down for 1 hour each day. d. Elevate casted arm when resting and when sitting up.
D The injured extremity should be kept elevated while resting and in a sling when upright. This will increase venous return. Swelling of the fingers may indicate neurovascular damage and should be reported immediately. Permanent damage can occur within 6 to 8 hours. Joints above and below the cast on the affected extremity should be moved. The affected limb should not hang down for any length of time.
The nurse is caring for an intubated infant with botulism in the pediatric intensive care unit. Which health care provider prescription should the nurse clarify with the health care provider before implementing? a. Administer 250 mg botulism immune globulin intravenously (BIG-IV) one time. b. Provide total parenteral nutrition (TPN) at 25 ml/hr intravenously. c. Titrate oxygen to keep pulse oximetry saturations greater than 92. d. Administer gentamicin sulfate (Garamycin) 10 mg per intravenous piggyback every 12 hours.
D The nurse should clarify the administration of an aminoglycoside antibiotic. Antibiotic therapy is not part of the management of infant botulism because the botulinum toxin is an intracellular molecule, and antibiotics would not be effective; aminoglycosides in particular should not be administered because they may potentiate the blocking effects of the neurotoxin. Treatment consists of immediate administration of botulism immune globulin intravenously (BIG-IV) without delaying for laboratory diagnosis. Early administration of BIG-IV neutralizes the toxin and stops the progression of the disease. The human-derived botulism antitoxin (BIG-IV) has been evaluated and is now available nationwide for use only in infant botulism. Approximately 50% of affected infants require intubation and mechanical ventilation; therefore, respiratory support is crucial, as is nutritional support, because these infants are unable to feed.
The nurse is caring for a 4-year-old child immobilized by a fractured hip. Which complication should the nurse monitor related to the child's immobilization status? a. Metabolic rate increases b. Increased joint mobility leading to contractures c. Bone calcium increases, releasing excess calcium into the body (hypercalcemia) d. Venous stasis leading to thrombi or emboli formation
D The physiologic effects of immobilization, as a result of decreased muscle contraction, include venous stasis. This can lead to pulmonary emboli or thrombi.
