Following a severe motor vehicle accident, a 10-year-old male
has a hemisection of the
spinal cord with associated ipsilateral weakness and loss of
proprioception and contralateral
loss of pain and temperature sensation. What is this spinal
cord syndrome called?
A. Anterior cord syndrome
B. Complete cord injury
C. Brown-Sequard syndrome
D. Posterior cord syndrome
C: Hemisection of the spinal cord, severing it on one side only,
and its associated symptoms are referred to as Brown-
Sequard syndrome. Anterior cord syndrome results in loss of
motor abilities and some sensations (temperature, pain,
vibration) below injury. Posterior cord syndrome retains motor
functions but some sensation is lost below injury. Complete
cord injury results in bilateral paralysis and lack of sensation
below injury.
A 2-year-old male inadvertently ingests some opiates from his
parent's prescription
medication. Which of the following would NOT be a likely
physical finding?
A. Decreased respiratory rate.

,B. Lethargy.
C. Decreased bowel sounds.
D. Pupillary dilation.
D: Pupillary constriction, not dilation, is a hallmark of opiate
overdose. Decreased respiratory rate, lethargy, and decreased
bowel sounds are common physical symptoms of opiate
overdose.
A 10-year-old child is to have a venipuncture done at the
femoral site. Which of the
following anatomic structures is most medial in the inguinal
area?
A. Femoral vein.
B. Femoral artery.
C. Femoral nerve.
D. Anterior superior iliac crest.
A: The femoral vein is the most medial structure in the inguinal
canal, so venipuncture should be attempted medially to where
the femoral artery is palpated at the femoral triangle.
An early-adolescent female is described by her mother as
having no interest in participating
in any activities with her parents. What aspect of psychosocial
development does this reflect?
A. Identity.
Page 2 of 154
,B. Peer pressure.
C. Body Image.
D. Independence.
D: Decreased interest in parental activities is consistent with
independence activities in which the adolescent begins to
move away from the dependence of childhood to establish her
own identity. This period is often characterized by rebellion
and withdrawal from the family.
Hemolytic uremic syndrome (HUS) is a post-infectious
disorder causing nephropathy,
hemolytic anemia, and thrombocytopenia. It is seen following
upper respiratory illnesses and
following GI infections after eating meat contaminated with
bacteria. What enteric bacteria
have been linked to HUS?
A. Escherichia coli O157:H7.
B. Clostridium difficile.
C. Rotavirus.
D. Vibrio cholera.
A: E. coli O157:H7 from contaminated ground meat is the most
common bacterial cause of HUS although other bacteria, such
as Shigella dysenteriae, may also cause HUS.
Hypertension can be seen in the pediatric population. What is
the most common cause of
Page 3 of 154
, secondary hypertension in children?
A. Coarctation of the aorta.
B. Renal disease.
C. Neuroblastomas.
D. Drug toxicity.
B: Renal disease is the most common cause of secondary
hypertension in the pediatric population. Coarctation of the
aorta, neuroblastoma, and drug toxicity are less common
causes of secondary hypertension. Primary hypertension is
also on the rise, related to obesity, lack of exercise, and poor
nutrition
A 16-year-old female is brought into the ED with an intentional
overdose of acetaminophen.
In order to prevent liver toxicity what medication can be given?
A. N-Acetylcysteine (Mucomyst).
B. Activated charcoal.
C. Ipecac syrup.
D. Naloxone (Narcan).
A: N-Acetylcysteine (Mucomyst) is the medication used for
acetaminophen overdoses. Toxicity occurs with dosage >140
mg/kg in one dose or >7.5g in 24 hours. The 72-hour N-
acetylcysteine (NAC) protocol includes 140 mg/kg initially and
70 mg/kg every 4 hours for 17 more doses (orally or IV).
Naloxone is used for opiate overdoses, and activated charcoal
is used for numerous other medication overdoses.
