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?
Anterior cord syndrome
Complete cord injury
Brown-Sequard syndrome
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.
Lethargy.
Decreased bowel sounds.
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.
Femoral artery.
Femoral nerve.
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.
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?
Escherichia coli O157:H7.
Clostridium difficile.
Rotavirus.
, 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
secondary hypertension in children? A. Coarctation of the aorta.
Renal disease.
Neuroblastomas.
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?
N-Acetylcysteine (Mucomyst).
Activated charcoal.
Ipecac syrup.
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.
