Q
  1. A 2-year-old child cannot raise his arm completely on
    the right and has torticollis. He has no other congenital
    abnormalities. Which of following is the most likely
    diagnosis?
    A. Slipped capital femoral epiphysis
    B. Juvenile rheumatoid arthritis
    C. Sprengel deformity
    D. Amold-Chiari malformation
    E. Cerebral palsy
A
  1. Answer: C
    Explanation:
    (Seidel, 5/e, p 762.)
    A child with Sprengel deformity
    cannot raise one arm completely due to a small and
    elevated scapula. Torticollis (wry neck due to shortening
    of the sternocleidomastoid muscle) often accompanies the
    deformity. Adolescents with slipped capital femoral
    epiphysis (SCFE) are often obese African American males
    who present with thigh or knee pain. SCFE is a disorder of
    unknown etiology that causes posterior and medial
    displacement of the femoral head. Children with juvenile
    rheumatoid arthritis (JRA) present with fever, salmoncolored
    rash, arthritis, hepatosplenomegaly, nodules,
    pericarditis, and iridocyclitis (may lead to blindness).
    There is no diagnostic test for JRA, but the disease resolves
    by puberty in the majority of children. Arnold-Chiari
    malformation is an abnormality of neural tube closure.
    Cerebral palsy (CP) is a nonprogressive disorder
    resulting from a perinatal insult; it causes either a spastic
    paresis of the limbs or extrapyramidal symptoms (chorea,
    athetosis, ataxia). Patients with CP often have an
    associated seizure disorder, mental retardation, and speech
    or sensory defi cits

of child abuse?
A. Epiphyseal
B. Diaphyseal
C. Growth plate
D. Metaphyseal
E. Torus
A
  1. Answer: D
    Explanation:
    Metaphyseal fractures, such as bucket handle and corner
    fractures are more likely in abuse situations. Other
    common fi ndings in abuse include posterior rib, sternum,
    spinous process fractures and fractures of different ages.

Q
1668. The most common malignant bone tumor in children is
A. Osteosarcoma
B. Ewing’s sarcoma
C. Neuroblastoma
D. Wilm’s tumor
E. Leukemia
A
  1. Answer: A
    Explanation:
    Malignancies of the bone, with an average annual
    incidence rate of 8.7 per million children younger than 20
    years of age, comprised about 6% of childhood cancer. In
    the US, 650-700 children and adolescents younger than 20
    years of age are diagnosed with bone tumors each year of
    which approximately 400 are osteosarcoma and 200 are
    Ewing’s sarcoma. The two types of malignant bone cancer
    that predominated in children are osteosarcomas and
    Ewing’s sarcomas, about 56% and 34% of the malignant
    bone tumors, respectively

Q

1669.Two weeks after a viral syndrome, a 9-year-old girl
presents to your clinic with a complaint of several days
of drooping of her mouth. In addition to the drooping of
the left side of her mouth, you note that she is unable to
completely shut her left eye. Her smile is asymmetric, but
her examination is otherwise normal. This girl likely has
A. Guillain-Barre syndrome
B. Botulism
C. Cerebral vascular accident
D. Brainstem tumor
E. Bell’s palsy

A
  1. Answer: E
    Explanation:
    Reference: Behrman, 16/e, p 1893. McMillan, 3/e, p 1963.
    Rudolph, 21/e, p 2366.
    Bell’s palsy is an acute, unilateral facial nerve palsy that
    begins about 2 weeks after a viral infection. The exact
    pathophysiology is unknown, but it is thought to be
    immune. On the affected side, the upper and lower face are
    typically paretic, the mouth droops, and the patient cannot
    close the eye. Treatment consists of maintaining moisture
    to the affected eye (especially at night) to prevent keratitis.
    Complete, spontaneous resolution occurs in about 85% of
    cases, 10% of cases have mild residual disease, and about
    5% of cases do not resolve.

Q
  1. Your 6-year-old son awakens at 1:00 A.M. screaming. He
    has been hyperventilating, tachycardic, and has dilated
    pupils. He cannot be consoled, does not respond, and
    is unaware of his environment. After a few minutes, he
    returns to normal sleep. He recalls nothing the following
    morning. The most likely diagnosis is
    A. Seizure disorder
    B. Night terrors
    C. Drug ingestion
    D. Psychiatric disorder
    E. Migraine headache
A
  1. Answer: B
    Explanation:
    Reference: Behrman, 16/e, pp 16, 1829. McMillan, 3/e, p
  2. Rudolph, 21/e, pp 34, 418, 2273.
    Night terrors are most common in boys between the ages
    of 5 and 7 years. The child awakens suddenly, appears
    frightened and unaware of his surroundings, and has the
    clinical signs outlined in the question. He cannot be
    consoled by the parents. After a few minutes, sleep returns,
    and the patient cannot recall the event in the morning.
    Sleepwalking is common in these children. Exploring the
    family dynamics for emotional disorders may be helpful;
    usually pharmacologic therapy is not required, and family
    reassurance is indicated.

Q

1673.A 9-year-old child has developed headaches that are
more frequent in the morning and are followed by
vomiting. Over the previous few months, his family has
noted a change in his behavior (generally more irritable
than usual) and his school performance has begun to
drop. Imaging of this child is most likely to reveal a lesion
that is
A. Subtentorial
B. Supratentorial
C. Intraventricular
D. In the spinal canal
E. In the peripheral nervous system

A
  1. Answer: A

    Between 50 and 60% of tumors of the nervous system in
    children 4 to 11 years old are infrartentorial (posterior
    fossa) and include cerebellar and brainstem tumors, often
    either medulloblastoma or cerebellar astrocytoma. In
    adults and infants, most intracranial tumors originate
    above the tentorium; only 25 to 30% of brain tumors in
    adults are subtentorial.

    “lump” of soft tissue overlying the lower spine.
    Evaluation with ultrasound of this lesions may
    A. Ebstein pearl
    B. Mongolian spot
    C. Cephalohematoma
    D. Omphalocele
    E. Occult spina bifi da
A
  1. Answer: E
    Explanation:
    Reference: Behrman, 16/e, p 1803-1806. McMillan, 3/e, p
    223-224. Rudolph, 21/e, p2185.
    Mongolian spot is not related to any abnormality. Virtually
    any abnormality (except Mongolian spots) over the lower
    spine points to the possibility of occult spinal dysraphism.
    This designation includes a number of spinal cord and
    vertebral anomalies that frequently produce severe loss of
    neurologic function, particularly in the region of the back,
    the lower extremities, and the urinary system. Examples of
    these abnormalities are subcutaneous
    lipomeningomyelocele, diastematomyelia, hamartoma,
    lipoma, tight fi lum terminale, tethered cord, dermal and
    epidermal cysts, dermal sinuses, neurenteric canals, and angiomas. Occasionally, the loss of neurologic function
    from such anomalies is mild and, as a result, easily
    overlooked. Prompt evaluation of these lesions via CT,
    MRI, or ultrasound is indicated.

Q
  1. With regard to the fetal circulation
    A. the right ventricle ejects one-third of the ventricular
    output
    B. it is arranged in series
    C. placental blood is well oxygenated
    D. 50 percent of the blood entering the pulmonary artery is
    shunted to the aorta
    E. 20 percent of the blood entering the pulmonary artery is
    shunted to the aorta
A
  1. Answer: C
    Explanation:
    (Miller, 4/e. p 2078.)
    The right ventricle ejects two-thirds of the combined
    ventricular output. The adult circulation is arranged in
    series; the fetal circulation is in parallel. Blood returning
    from the placenta is well oxygenated. Approximately 95
    percent blood entering the pulmonary artery is shunted
    through the ductus arteriosus to the aorta.

  1. A 4-year-old child falls from the back of a three-wheeled
    vehicle, hitting his head. He experiences no loss of
    consciousness. In the emergency room, he is alert and
    oriented without focal fi ndings on examination. He has
    blood behind his left tympanic membrane. CT scan of the
    skull is likely to show
    A. Subdural hematoma
    B. Epidural hematoma
    C. Intraventricular hemorrhage
    D. Basilar skull fracture
    E. Hydrocephalus
A
  1. Answer: D
    Explanation:
    Reference: Behrman, 16/e, p 1961. McMillan, 3/e, p 611.
    Rudolph, 21/e, p2242-2244.
    The history, signs, and symptoms as outlined in the
    question are characteristics of a basilar skull fracture.
    Those patients with rupture of the tympanic membrane
    allowing otorrhea and those with rhinorrhea after the
    injury are at increased risk of complications of infection.
    For these children, a semi-upright position and
    observation for 72 h for evidence of increased intracranial
    pressure or infection without use of prophylactic
    antibiotics is appropriate. Cerebrospinal fl uid (CSF)
    drainage frequently stops within 72h. Drainage beyond 72
    h can require surgical closure; the risk of complications
    such as infection increases after this time.

Q
  1. A 9-year-old girl is brought to you with the complaint of
    severe intermittent headaches for the last several months.
    The physical examination, including a careful neurologic
    examination, is normal. The following characteristics
    support the diagnosis of childhood migraine in this
    patient:
    A. Strong family history of migraine
    B. Frequently isolated to the occipital region
    C. Frequently associated with attention defi cit hyperactive
    disorder
    D. Duration of headache more than 24h
    E. Persistence of headache after sleep
A
  1. Answer: A
    Explanation:
    Reference: Behrman, 16/e, pp 1832-1834. McMillan, 3/e,
    pp 679-680, 1931-1932, 2027-2029. Rudolph, 21/e, pp
    2274-2276.
    In contrast to adults, children with migraine
    most often have “common” migraine: bifrontal headache
    without an aura or diffuse throbbing headache of only a
    few hours’ duration. As with adults, the headaches can be
    terminated with vomiting or sleep. Family history is
    frequently positive. Association with attention defi cit
    hyperactive disorder is not common, but a relationship with seizure disorder can be seen.

    nonverbal techniques are used to assess the intensity of
    their pain. A practical, reliable, and easy-to-apply bedside
    guide is a faces scale, such as the Oucher scale.

Q

1683.All the following statements concerning the fetal
hematologic system are true EXCEPT
A. physiologic anemia occurs at 1 month of age
B. fetal hemoglobin has P-50 of 19mmHg compared with
26mmHg for adult hemoglobin
C. fetal hemoglobin has a greater affi nity for O2, and this
manifests as decreased O2 delivery to the periphery
compared with adult hemoglobin
D. the decreased P-50 of fetal hemoglobin causes a shift to
the left of the oxygen dissociation curve
E. decreased release of oxygen by fetal hemoglobin is offset
by increased oxygen delivery provided by elevated hemoglobin
concentrations in neonates

A
  1. Answer: A
    Explanation:
    (Stoelting, Anesthesia and Co-Existing Disease, 3/e. p
    583.)
    There are differences between fetal hemoglobin and adult
    hemoglobin that infl uence O2 transport and delivery. Fetal
    hemoglobin has a greater affi nity for oxygen, which results
    in a lower P-50 (19 mmHg) and causes a shift to the left
    of the O2 dissociation curve. For these reasons, there is
    decreased release of O2 to the periphery. However, there is
    a greater amount of fetal hemoglobin, and this offsets the
    increased affi nity by increasing delivery of O2. Physiologic
    anemia occurs at about 2 to 3 months of age, when
    production of adult hemoglobin begin in earnest.

1684.A previously healthy 7-year-old child suddenly complains
of a headache and falls to the fl oor. When examined in the
emergency room, he is lethargic and has a left central
facial weakness and left hemiparesis with conjugate
ocular deviation to the right. The most likely diagnosis is
A. Hemiplegic migraine
B. Supratentorial tumor
C. Todd’s paralysis
D. Acute subdural hematoma
E. Acute infantile hemiplegia

A
  1. Answer: E
    Explanation:
    Reference: Behrman, 16/e, pp 1854-1855. McMillan, 3/e,
    pp 614-615, 1929,1931-1933. Rudolph, 21/e, pp 2246-
    2248, 2257-2258, 2261, 2274-2275.
    The abrupt onset of a hemisyndrome, especially with the
    eyes looking away from the paralyzed side, strongly
    indicates a diagnosis of acute infantile hemiplegia. Most
    frequently, this represents a thromboembolic occlusion of
    the middle cerebral artery or one of its major branches.
    Hemiplegic migraine commonly occurs in children with a
    history of migraine headaches. Todd’s paralysis follows
    after a focal or Jacksonian seizure and generally does not
    last more than 24 to 48 h. The clinical onset of
    supratentorial brain tumor is subacute, with repeated
    headaches and gradually developing weakness. A history
    of trauma usually precedes the signs of an acute subdural
    hematoma. Clinical signs of other diseases can appear
    fairly rapidly, but not often with the abruptness of
    occlusive vascular disease.

Q
  1. A 16-year old high school student was running track
    and developed sudden pain in the leg with tenderness on
    palpation and tingling. Subsequently, pain increased in
    intensity with ankle swelling and erythema. MRI showed
    no evidence of fracture but edema of muscles in the lower
    leg was observed. The most likely diagnosis is:
    A. Complex regional pain syndrome
    B. Tarsal tunnel syndrome
    C. Peroneal tenosynovitis
    D. Compartment syndrome
    E. Achilles tendonitis
A
  1. Answer: C
    Explanation:
    The sudden onset with exercise, swelling and tingling
    suggest compartment syndrome. All the conditions may
    cause leg and ankle pain. Different Achilles affl ictions
    present with distinctive clinical features. Achilles tendon
    tears can be sustained during a traumatic incident and can
    mimic other tendonopathies. Tarsal tunnel syndrome
    involves the motor and sensory branches of the tibial
    nerve (L4 to S3) as it travels deep to the fl exor
    retinaculum. Ischemia to the tibial nerve occurs after
    fracture of the medial malleolus, calcaneus, or
    sustentaculum tali. Continued distally, a “joggers’ foot” is
    typically associated with medial plantar nerve entrapment
    due to hyperpronation (eccentric loading) in long distance
    runners. Impression occurs at the abductor hallucis
    insertion with the patient complaining of symptoms from
    the medial longitudinal arc to the toes during and after
    exercise.
    With the chronic compartment syndrome, the changes are
    reversible and the involved muscles may be completely
    normal between episodes. The patient’s initial complaint
    includes a deep ankle pain over the anterolateral
    compartments of the leg during or after a relatively long
    period of exercise; the pain disappears with cessation of
    activity. Symptoms often interfere enough to cause the
    athlete to either rest or reduce the intensity of the activity,
    and the symptoms may be reproduced by either
    dorsifl exion or plantarfl exion of the foot. Patients with
    recurrent exertion compartment syndrome are at risk for
    developing peroneal muscle herniations at the fascial
    tunnel in the anterolateral distal leg. This tunnel serves as
    a hiatus and source of intercompartment relief of pressure
    buildup.
    In acute compartment syndrome, continued, mounting
    pressure causes pain out of proportion, pulselessness, and
    dramatic pain on passive stretching of the muscle in the
    involved compartment; this causes irreversible tissue
    necrosis.
    Exertional compartment syndromes are often exerciseinduced,
    and typically occur either chronically in well
    trained athletes or acutely in individuals preforming
    unaccustomed exercises, such as marching or prolonged
    running. A compartment syndrome occurs when
    increased pressure within a limited space comprises the
    circulation to the contents of that space, resulting in
    reduction of muscle and nerve profusion. In both traumatic and exercise-induced compartment syndromes,
    the muscles
    within the compartment enlarge with lactate and cause a
    reduction in blood fl ow to the relatively small anterior and
    lateral crural compartments. Muscle bulk increases by
    20% after exercise. This is not to be confused with
    anterior shin splint syndrome, which shows no pressure
    elevation with the anterolateral compartment of the leg.
    Individual variation in the relationship of muscle bulk to
    the compartment volume may account for the
    susceptibility of certain persons to exercise-induced
    compartment syndrome. Even though the
    pathophysiology of both forms of compartment syndrome
    are essentially the same, the end result of the acute form
    differs from that of the chronic. In both conditions,
    ischemia resulting from abnormal pressure causes pain.

  1. A 7 -year-old boy presents with a I-year history of pain
    of the left anterior thigh. He has no history of trauma.
    On physical examination, he has limited hip motion,
    especially with abduction and internal rotation. A slight
    limp is noticeable with ambulation. Pain is brought on by
    activity and improves with rest. Which of the following is
    the most likely diagnosis?
    A. Osteochondrosis
    B. Osgood-Schlatter disease
    C. Muscular dystrophy
    D. Rickets
    E. juvenile rheumatoid arthritis
A
  1. Answer: A
    Explanation:
    A. Osteochondrosis is an uncommon disorder that affects
    boys more than girls between the ages of 2 and 12.

Q
  1. A 16-year-old basketball player complains of pain in
    his knees. A physical examination reveals, in addition to
    tenderness, a swollen and prominent tibial tuberosity.
    Radiographs of the area are unremarkable. The most likely diagnosis is
    A. Osgood-Schlatter disease
    B. Popliteal cyst
    C. Slipped capital femoral epiphysis
    D. Osteochondrosis
    E. Gonococcal arthritis
A
  1. Answer: A
    Explanation:
    Reference: Behrman, 16/e, pp 2075-2076, 2080-2082,
  2. McMillan, 3/e, pp 749, 2109-2110. Rudolph, 21/e,
    pp 2432, 2437-2438.
    This history is typical of Osgood-Schlatter disease.
    Microfractures in the area of the insertion of the patellar
    tendon into the tibial tubercle are common in athletic
    adolescents. Swelling, tenderness, and an increase in size of
    the tibial tuberosity are found. Radiographs can be
    necessary to rule out other conditions. Treatment consists
    of rest.
    Osteochondrosis is avascular necrosis of the femoral head.
    This condition usually produces mild or intermittent pain
    in the anterior thigh but can also present as a painless
    limp.
    Gonococcal arthritis, although common in this age range,
    is uncommon in this anatomic site. More signifi cant
    systemic signs and symptoms, including chills, fever,
    migratory polyarthralgias, and rash, are commonly seen.
    Slipped capital femoral epiphysis is usually seen in a
    younger, more obese child (mean age about 10 years) or in
    a thinner, older child who has just undergone a rapid
    growth spurt. Paid upon movement of the hip is
    diagnostic.
    Popliteal cysts are found on the posterior aspect of the
    knee.

Q
  1. A 3-year-old boy’s parents complain that their child has
    diffi culty walking. The child rolled, sat, and fi rst stood at
    essentially normal ages and fi rst walked at 13 months of
    age. Over the past several months, the family has noticed
    an increased inward curvature of the lower spine as he
    walks and that his gait has become more “waddling” in
    nature. On examination, you confi rm these fi ndings and
    also notice that he has enlargement of his calves. This
    child most likely has
    A. Occult spina bifi da
    B. Muscular dystrophy
    C. Brain tumor
    D. Guillain-Barre syndrome
    E. Botulism
A
  1. Answer: B
    Explanation:
    Reference: Behrman, 16/e, pp 1873-1877. McMillan, 3/e,
    pp 1972-1976. Rudolph, 21/e, pp 2289-2293.
    The most common form of muscular dystrophy is
    Duchenne muscular dystrophy. It is inherited as an Xlinked
    recessive trait. Male infants are rarely diagnosed at
    birth or early infancy since they often reach gross
    milestone at the expected age. Soon after beginning to
    walk, however, the features of this disease become more
    evident. While these children walk at the appropriate age,
    the hip girdle weakness is seen by age 2. Increased lordosis
    when standing is evidence of gluteal weakness. Gower sign
    (use of the hands to “climb up” the legs in order to assume
    the upright position) is seen by 3 to 5 years of age, as is
    the
    hip waddle gait. Ambulation ability remains through
    about 7 to 12 years, after which use of a wheelchair is
    common. Associated features include mental impairment
    and cardiomyopathy. Death due to respiratory failure,
    heart
    failure, pneumonia, or aspiration is common by 18 years
    of age.

A. high pulmonary vascular resistance
B. low systemic vascular resistance
C. right-to-left shunting of blood through the foramen
ovale
D. right-to-left shunting of blood through a ventricular

delivery
E. right-to-left shunting of blood via the ducts arteriosus

A
  1. Answer: D
    Explanation:
    Stoelting, Anesthesia and Co-Existing Disease, 3/e. pp 37-

    A ventricular septal defect (VSD) is not a normal
    component of the fetal circulation pattern. VSDs
    constitute
    approximately 28 percent of congenital cardiac anomalies, and they are more common in premature infants. Twentyeight
    percent of VSDs are small and will close
    spontaneously. The symptoms of a large VSD include
    tachypnea, tachycardia, failure to thrive, recurrent
    pulmonary infections, and ultimately congestive heart
    failure. If medical management is unsuccessful, surgical
    treatment, which depends on the type of VSD, is
    considered.

immunization card and suddenly realize that he has
failed to get vaccinated for
A. Mumps
B. Varicella
C. Rubella
D. Measles
E. Herpangina

A
  1. Answer: A
    Explanation:
    Reference: Behrman, 16/e, pp 817-820, 946-955, 961-962,
    973-977. McMillan 3/e, pp 704, 1127-1130, 1134-1142.

    In addition to the fi ndings described, mumps typically
    swells to the opposite side in a day or so after symptoms
    appear on the fi rst side. Other fi ndings include redness
    and swelling at the opening of Stensen’s duct, edema and
    swelling in the pharynx, and displacement of the uvula on
    the affected side. A rash would not be expected. Measles
    presents in a child with a several day history of malaise,
    fever, cough, coryza, and conjunctivitis followed by the
    typical, widespread, erythematous, maculopapular rash.
    Koplik spots, white pinpoint lesions on a bright red buccal
    mucosa often in the area opposite his lower molars,
    appear transiently and are pathognomonic. Symptoms of
    rubella, usually a mild disease, include diffuse
    maculopapular rash that lasts for 3 days, marked
    enlargement of the posterior cervical and occipital lymph
    nodes, low-grade fever, mild sore throat, and, occasionally
    , conjunctivitis, arthralgia, or arthritis. Signs and
    symptoms of varicella include a prodrome of fever,
    anorexia, headache, and mild abdominal pain, followed 24
    to 48 h later by the typical clear, fl uid fi lled vesicles
    (dewdrop on a rose petal). The rash of varicella typically
    starts on the scalp, face, or trunk. The lesions are pruritic
    and appear in crops over the next several days, with old
    lesions crusting over as new lesions develop. Herpangina
    causes sudden (usually high) fever, headache, backache,
    and, frequently, vomiting. Oral lesions are vesicles or ulcers
    usually found on the anterior tonsillar pillars, but can
    occur nearly anywhere in the mouth. They are caused by
    an enterovirus for which vaccination is not available.

Q
  1. The following statements about thermoregulation in the
    neonate are all true EXCEPT
    A. neonates have a larger body surface area compared with
    body weight than do adults
    B. neonates have mature central thermoregulatory control
    C. neonates have a specialized ability to produce heat
    D. neonates have a very thin layer of subcutaneous fat
    E. neonates cannot shiver to produce heat
A
  1. Answer: B
    Explanation:
    (Stoelting, Anesthesia and Co-Existing Disease, 3/e. pp
    583-584.)
    Neonates are particularly prone to hypothermia in the
    operating room as their central thermoregulatory controls
    are immature. They have a large ratio of body surface are
    to body weight and lose heat more quickly than adults do.
    Neonates also have less insulating subcutaneous fat than
    do adults. Infants do not shiver to produce heat. Heat is
    generated from the metabolism of the brown fat they
    possess. Methods to prevent heat loss in neonates include
    increasing the operating room temperature, warming
    fl uids, heating and humidifying gases, covering exposed
    body surfaces, and using radiant-heat tables in the
    operating room.

    A. Hypoxia leads to sustained hyperventilation
    B. Hypercarbia leads to sustained hyperventilation
    C. The ventilatory response to hypercarbia in newborns is
    mature at birth
    D. With both hypoxia and hypercarbia, newborns respond
    initially by hyperventilating but then start to hypoventilate
    E. None of the above
A
  1. Answer: D
    Explanation:
    (Stoelting, Anesthesia and Co-Existing Disease, 3/e. pp
    579-580.)
    Control of ventilation in premature infants and neonates
    is immature. When neonates are subjected to hypoxia or
    hypercarbia, for 1 to 2 min, there is hyperventilation. After
    this time, the neonate will hypoventilate and may even
    become apneic. High levels of carbon dioxide may be a
    respiratory depressant in neonates. Respiratory
    depressants will act synergistically with the immature
    response to ventilation. It must also be remembered that
    oxygen consumption and carbon dioxide production in a
    neonate are double those in an adult.

Q
  1. About 12 days after a mild upper respiratory infection,
    a 12-year-old boy complains of weakness in his lower
    extremities. Over several days, the weakness progresses
    to include his trunk. On physical examination, he has the
    weakness described and no lower extremity deep tendon
    refl exes, muscle atrophy, or pain. Spinal fl uid studies
    are notable for elevated protein only. The most likely
    diagnosis in this patient is
    A. Bell’s palsy
    B. Muscular dystrophy
    C. Guillain-Barre syndrome
    D. Charcot-Marie-Tooth disease
    E. Werdnig-Hoffmann disease
A
  1. Answer: C
    Explanation:
    Reference: Behrman, 16/e, pp 1892-1893. McMillan, 3/e,
    pp 1959-1965, 1972-1976. Rudolph, 21/e, pp 2281-2283.
    The paralysis of Guillain-Barre occurs about 10 days after
    a nonspecifi c viral illness. Weakness is gradual over days
    or weeks, beginning in the lower extremities and
    progressing toward the trunk. Later, the upper limbs and
    the bulbar muscles can become involved. Involvement of
    the respiratory muscles is life threatening. The syndrome seems to be caused by a demyelination in the motor and,
    occasionally, the sensory nerves. Measurement of spinal
    fl uid protein is helpful in the diagnosis; protein levels are
    increased to more than twice normal, while glucose and
    cell counts are normal. Hospitalization for observation is
    indicated. Treatment can consist of intravenous
    immunoglobulin, steroids, or plasmapheresis. Recovery is
    not always complete. Bell palsy usually follows a mild
    upper respiratory infection, resulting in the rapid
    development of weakness of the entire side of the face.
    Muscular dystrophy encompasses a number of entities that
    include weakness over months. Charcot-Marie-Tooth
    disease has a clinical onset including peroneal and intrinsic
    foot muscle atrophy, later extending to the intrinsic hand
    muscles and proximal legs. Werdnig-Hoffmann disease is
    an anterior horn disorder that presents either in utereo (in
    about one-third of cases) or by the fi rst 6 months of life
    with hypotonia, weakness, and delayed developmental
    motor milestones.

1697.The following idiopathic scoliosis would be most
commonly found in girls age range:
A. Birth to 3 years
B. 4 to 10 years
C. 11 to 18 years
D. 19 to 25 years
E. >25 years
A
  1. Answer: C
    Explanation:
    Reference: Behrman, 16/e, pp 2083-2084. McMillan, 3/e,
    pp 2117-2121. Rudolph, 21/e, pp 2000-2001.
    The most common form of scoliosis is idiopathic
    scoliosis. Three age ranges of idiopathic scoliosis exist:
    infantile (which presents at birth to 3 years of age),
    juvenile (presenting at 4 to 10 years age), and adolescent
    (the most common form, accounting for 80% of cases and
    presenting from 11 years and older). To diagnose this
    condition, the back is viewed from behind, with the
    patient in the standing position. The waist, shoulders, and
    pelvis should be symmetric. The spine is examined for
    symmetry or deformity. The patient is then asked to bring
    the palms together in the front and bend at the waist.
    Viewing the patient from behind will allow for
    identifi cation of any humps, valleys, or other deformities
    of the spine. Identifi ed abnormalities can be confi rmed
    radiographically. Premenarchal girls with a curvature of
    the spine of more than 20° on radiographs need close
    follow-up every 4 to 6 months because the risk of
    progression is high.

1711.True statements regarding the use of opioids for pain
management in children include the following :
1. Minor side effects occur more commonly in children
than adults
2. The incidence of respiratory depression is directly related
to dose
3. Meperidine is preferred over morphine
4. Tolerance is an uncommon clinical problem in children

A
  1. Answer: C (2 & 4)
    Explanation:
    (Ferrante, pp 491-492.)
    Meperidine is not routinely used
    in infants and children because of prolonged elimination
    half-life in neonates (6 to 39 h) and because repeated
    administration may lead to an accumulation of the
    normeperidine metabolite, which may produce CNS
    excitation and seizures. The incidence of respiratory
    depression with mu agonists is directly related to the dose.
    Minor opioid side effects (e.g., nausea and vomiting)
    occur no more frequently in children than in adults.
    Tolerance is an uncommon clinical problem in children

    in order to suppress afferent small fi ber input into the spinal cord
  4. High intensity, low frequency stimulation is thought to
    work via a naloxone reversible mechanism
  5. Low frequency, high pulse duration cause strong muscle
    contractions
A
  1. Answer: E
    Explanation:
    The gate control theory explains the mechanisms of pain
    relief associated with TENS treatment for many
    conditions. Simply stated, this theory proposed the
    existence of a gating mechanism in the dorsal horns of the
    spinal cord, where there is an interaction between the
    small-diameter, unmyelinated C fi bers, which mediate the
    transmission of pain, and the larger-diameter, myelinated
    A fi bers, which mediate sensation of light touch and
    pressure.
    High-intensity, low-frequency stimulation (frequently
    referred to as “acupuncture-like TENS”) also appears to
    offer pain relief, the effects of which can be reversed with
    naloxone, an opiate antagonis
    Central to the discussion of the rationale of TENS therapy
    are its various stimulation parameters. Low-frequency and
    high-pulse [width] energy cause strong, rhythmic muscle
    contractions.

Q

1719.True statements concerning fl uid and electrolyte
management in pediatric patients include which of the
following?
1. Because of the greater hypoxic damage associated with
high blood glucose levels and the infrequent occurrence
of hypoglycemia in newborns, administration of a dextrose
containing solution is not recommended
2. During the fi rst days of life, term newborns need a
larger volume of maintenance fl uid per kilogram of
body weight than do older children
3. Replacement fl uid for defi cit and third-space loss should be hypotonic given the inability of young infants to
handle an excess sodium load
4. To minimize dehydration, restriction of fl uids in a neonate
should be less than 2 to 4 h

A
  1. Answer: D (4 Only)
    Explanation:
    (Miller, 4/e. pp 2108-2109, 2112-2113.)
    The greater hypoxic damage associated with high blood
    glucose levels has been shown only in animal studies.
    Hypoglycemia in newborns is a real concern. Therefore,
    administration of a dextrose containing solution is
    recommended, but blood glucose levels should be
    monitored to prevent hyperglycemia. Term newborns do
    have a large ratio of body surface area to weight and a
    higher metabolic demand. Their maintenance fluid
    requirement, however, is usually lower during the first
    days of life because of their inability to excrete excess
    water. Replacement fluid for deficit and third-space loss
    should be an isotonic solution because of the inability of
    young infants to handle and eliminate excess free water
    load; they are better able to handle an excess sodium load.

Q
  1. True statements regarding pain assessment in nonverbal
    children include
  2. neurophysiologic elements involved in pain perception
    are present in preterm infants
  3. undesirable physiologic responses can be caused by pain
    in neonates
  4. hormonal-metabolic responses to noxious stimuli are
    present in preterm infants
  5. neonates experience pain
A
  1. Answer: E (All)
    Explanation:
    (Ferrante, pp 486-487.)
    Available data indicate that the
    neurophysiologic and neurochemical components
    necessary for the transduction, transmission, modulation,
    and perception of nociception are present in term and
    preterm infants. The hormonal-metabolic responses to
    noxious stimuli are also intact. Similarly, undesirable
    physiologic responses can be provoked by pain. Term and
    preterm infants can undergo substantial changes in
    hemodynamics, oxygen saturation, and intracranial
    pressure in response to noxious surgical stimuli. Thus, in
    contrast to previously held beliefs, the evidence suggests
    that neonates experience pain and should be treated for it.

Q
  1. Down’s syndrome is associated with
  2. a high incidence of congenital heart defects
  3. upper and lower airway abnormalities
  4. cervical neck instability
  5. sensitivity to atropine
A
  1. Answer: A (1, 2, & 3)
    Explanation:
    (Miller, 4/e. pp 968-969.)
    Patients with Down’s syndrome (trisomy 21) have a high
    incidence of congenital heart defects. They frequently also
    have upper and lower airway abnormalities. In addition,
    they may have atlanto-occipital instability (C1-C2). The
    previously reported sensitivity to atropine has been
    disproved.

Q
  1. True statements regarding the use of IV-PCA in children
    include
  2. it is safe and effective
  3. its use may be restricted by inability to activate the
    pump
  4. it can be used in children age 7 and older
  5. it is a universal therapy for postoperative pain control
    in children
A
  1. Answer: A (1, 2, & 3)
    Explanation:
    (Ferrante, pp 496-497.)
    IV-PCA appears to be safe and
    effective in children and is frequently preferred by nursing
    staff, parents, and particularly adolescent patients.
    However, there are a small number of older children and
    adolescents who may not wish to be bothered with selfmedication.
    They may feel indifferent and even dissatisfi ed
    with PCA and would rather receive analgesics by
    traditional methods. Therefore, PCA is not a universal
    therapy for postoperative pain control. IV-PCA can be
    used in children as young as 7 years of age. However, it
    may be restricted by age, developmental understanding of
    the purpose of PCA, and inability to activate the pump in
    the presence of muscular weakness or immobilization.

Q

1728.Which of the following medication regimens would be
appropriate for use in ventilated patient in an intensive
care unit?
1. Intravenous morphine and diazepam
2. Epidural morphine and local anesthetic with intravenous
diazepam
3. Intravenous fentanyl and midazolam
4. Epidural local anesthetic alone

A
  1. Answer: A (1, 2, & 3)
    Explanation:
    (Shoemaker, pp 796-799.)
    Ventilated patients in an intensive care setting require
    analgesia as well as sedation to alleviate anxiety and
    promote sleep. Intravenous opioids and benzodiazepines
    administered by infusion and supplemented with boluses
    as needed are quite effective. Epidural analgesia should be
    supplemented with intravenous benzodiazepines or other
    sedating medications that will provide anxiolysis and
    promote sleep.
