Maternal and Pediatric Nursing Exam Which set of symptoms are characteristic of 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 ANS: A Hypertonicity 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 neurological disorders. The parents of a child with cerebral palsy ask the nurse if any drugs can decrease their child's spasticity. What knowledge is the basis of the nurses' response? a. Anticonvulsant medications are sometimes useful for controlling spasticity. b. Medications that would be useful in reducing spasticity are too toxic for use in children. c. Many different medications can be highly effective in controlling spasticity. d. A pump can be implanted that delivers medication into the intrathecal space to decrease spasticity. ANS: 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 adverse effects of the drugs that reduce spasticity. Few medications are presently available for the control of spasticity. What term is used for a hernial protrusion of a saclike cyst of meninges spinal fluid and a portion of the spinal cord with its nerves through a defect in the vertebral column? a. Rachischisis b. Encephalocele c. Meningocele d. Myelomeningocele ANS: 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 spinal cord exposed. Encephalocele is a herniation of the 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 problem is most often associated with a myelomeningocele? a. Hydrocephalus b. Craniosynostosis c. Biliary atresia d. Esophageal atresia ANS: A Hydrocephalus is a frequently associated anomaly in 80 to 90% of children with myelomeningocele. Craniosynostosis is the premature closing of the cranial sutures and is not associated with myelomeningocele. Biliary and esophageal atresias are not associated with myelomeningocele. What is the most common problem for children born with a myelomeningocele? a. Neurogenic bladder b. Cognitive impairment c. Respiratory compromise d. Cranioschisis ANS: 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 and is not associated with myelomeningocele. Which supplement is recommended to prevent neural tube defects? a. Vitamin A throughout pregnancy b. Multivitamin preparations as soon as pregnancy is suspected c. Folic acid for all women of child-bearing age d. Folic acid during the first and second trimesters of pregnancy ANS: C The widespread use of folic acid among women of childbearing age is expected to decrease the incidence of spina bifida significantly. Vitamin A does not have a relation to the prevention of spina bifida. Folic acid supplementation is recommended for the preconception period and during the pregnancy but only 42% of women actually follow these guidelines. How much folic acid is recommended as a daily dose for women of child-bearing age? a. 0.1 mg b. 0.4 mg c. 1.5 mg d. 2 mg ANS: B It has been estimated that a daily intake of 0.4 mg of folic acid in women of child-bearing age will prevent 50 to 70% of cases of neural tube defects. A 0.1 mg dose is too low and 1.5 and 2 mg are not recommended dosages of folic acid. The nurse is caring for an infant born with a myelomeningocele. Surgery to repair the defect is scheduled for the next day. What is the most appropriate way to position and feed this newborn? a. Left lateral and tube feed b. Prone turn head to side and nipple feed c. Supine in infant carrier and nipple feed d. Supine with defect supported with rolled blankets and nipple feed ANS: B In the prone position feeding is a problem. The infant's head must be turned to one side for feeding. If the child is able to nipple feed there is no indication for tube feeding. Before surgery the infant should be kept in the prone position to minimize tension on the sac and risk of trauma. The nurse is talking to a parent with a child who has a latex allergy. Which statement by the parent indicates she correctly understands the teaching? a. "My child will have an allergic reaction if he comes in contact with yeast products." b. "My child may have an upset stomach if he eats foods made with wheat or barley." c. "My child will probably develop an allergy to peanuts." d. "My child should not eat bananas or kiwis." ANS: D There are cross-reactions between latex allergies and a number of foods such as bananas avocados kiwis and chestnuts. Although yeast products wheat and barley and peanuts are potential allergens they are currently not known to cross-react with latex. A latex allergy is suspected in a child with spina bifida. Which is an appropriate nursing intervention? a. Avoid using any latex product. b. Use only nonallergenic latex products. c. Administer medication for long-term desensitization. d. Teach the family about long-term management of asthma. ANS: A Care must be taken so 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 nonallergic 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. What clinical manifestation is suggestive of spinal muscular atrophy (Werdnig-Hoffmann disease) in an infant? a. Hyperactive deep tendon reflexes b. Hypertonicity c. Lying in the frog position d. Motor deficits on one side of body ANS: C The infant lies in the frog position with the legs externally rotated abducted and flexed at knees. Deep tendon reflexes are absent. The child has hypotonia and inactivity as the most prominent features. Motor deficits are bilateral. A young boy has just been diagnosed with pseudohypertrophic (Duchenne) muscular dystrophy. What should the management plan include? a. Recommend genetic counselling. b. Explain that the disease is easily treated. c. Suggest ways to limit the use of his muscles. d. Assist the family in finding a nursing facility to provide his care. ANS: A Pseudohypertrophic (Duchenne's) muscular dystrophy is inherited as an X-linked recessive gene. Genetic counselling 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 they possibly can are able to avoid wheelchair confinement for a longer time. Assisting the family in finding a nursing facility for the boy 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 14-year-old girl is in the critical care unit after a spinal cord injury 2 days ago. Which should be included in nursing care for this child? a. Avoiding the use of diazepam. b. Administering methylprednisone. c. Minimizing environmental stimuli. d. Discussing long-term care issues with the family. ANS: B Corticosteroids are administered to minimize the inflammation present at the injury site. Patients with spinal cord injury are physiologically labile so close monitoring is required. Diazepam is the medication of choice for seizure control and muscle relaxation therefore it should not be avoided. Minimizing environmental stimuli and discussing long-term care issues with the family actions do not apply to providing care for this patient. When assessing a child for botulism which are clinical manifestations? Select all that apply. Express answer in small letters followed by a comma and a space—e.g. a b c. a. Scotoma b. Weakness c. Headache d. Vomiting e. Diarrhea f. Exaggerated gag reflex ANS: B C D Clinical manifestations of botulism include weakness headache diplopia and vomiting. With infants they also experience constipation and a reduced gag reflex. What effect does immobilization have on metabolism? a. It causes hypocalcemia. b. It causes a decreased metabolic rate. c. It causes a positive nitrogen balance. d. It causes increased production of stress hormones. ANS: B Immobilization causes a decreased metabolic rate with the slowing of all systems and decreased food intake leads to hypercalcemia and causes a negative nitrogen balance secondary to muscle atrophy. The production of stress hormones decreases resulting in reduced physical and emotional coping capacity. What effect does immobilization have on the cardiovascular system? a. Venous stasis b. Increased vasopressor mechanism c. Normal distribution of blood volume d. Increased efficiency of orthostatic neurovascular reflexes ANS: A Because of the decreased muscle contraction the physiological effects of immobilization 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. The distribution of blood volume is altered with decreased cardiac workload and exercise tolerance. Immobilization causes a decreased efficiency in orthostatic neurovascular reflexes with an inability to adapt readily to the upright position and pooling of blood in the extremities in the upright position. What can result from the bone demineralization associated with immobility? a. Osteoporosis b. Urinary retention c. Pooling of blood d. Susceptibility to infection ANS: A Bone demineralization leads to a negative calcium balance osteoporosis pathological fractures extraosseous bone formation and renal calculi. Urinary retention is secondary to the effect of immobilization on the urinary tract. The 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. A young girl has just injured her ankle at school. In addition to calling the child's parents what is the school nurse's most appropriate immediate action? a. Apply ice. b. Observe the ankle for edema and discolouration. c. Encourage the child to assume a comfortable position. d. Obtain parental permission for administration of acetaminophen or aspirin. ANS: A Soft-tissue injuries should be iced immediately. In addition to ice the extremity should be rested and elevated and have compression applied. Observing for edema and discolouration encouraging the child to assume a comfortable position and obtaining parental permission or administration of acetaminophen or aspirin are not immediate priorities. What term is used to describe a fracture that does not produce a break in the skin? a. Simple b. Compound c. Complicated d. Comminuted ANS: 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. What is one advantage of using a fibreglass cast instead of a plaster one? a. It is less expensive. b. It dries rapidly. c. It moulds closely to body parts. d. It has a smooth exterior. ANS: B A synthetic casting material dries within minutes compared to a plaster cast which takes several hours to dry. Synthetic casts are more expensive not less. Plaster casts mould closer to body parts. Synthetic casts have a rough exterior which may scratch surfaces. The nurse is teaching the parents of a 7-year-old child who has just had a cast applied to a fractured arm with the wrist and elbow immobilized. What instruction should the nurse include in the discharge information? 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 the casted arm when resting and sitting up. ANS: 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 since permanent damage can occur within 6 to 8 hours. Joints above and below the cast on the affected extremity should be moved. The child should not engage in strenuous activity for the first few days. Rest with the extremity elevated is encouraged. Why does a nurse use the palms of his hands when handling a wet cast? a. To assess the dryness of the cast b. To facilitate easy turning c. To keep the patient's limb balanced d. To avoid indenting the cast ANS: D Wet casts should be handled with the palms of the hands not the fingers to prevent the creation of pressure points. Assessing dryness facilitating easy turning or 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. What causes 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 on the cast's surface ANS: D If hot spots are felt on the cast surface they usually indicate infection beneath the area. This should be reported so a window can be made in the cast to observe the site. The five P's of ischemia from a vascular injury include pain pallor pulselessness paresthesia and paralysis. Paresthesia is an indication of vascular injury not infection. Cold toes may be indicative of a cast that's too tight and need further evaluation. Increased respirations may indicate a respiratory infection or pulmonary emboli. This should be reported and the child should be evaluated. A child is upset because when the cast was removed from her leg the skin surface was caked with desquamated skin and sebaceous secretions. What should the nurse suggest to remove this material? a. Soak in a bathtub. b. Vigorously scrub the leg. c. Apply powder to absorb the material. d. Carefully pick the material off of the leg. ANS: A
