Question: 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). - CORRECT ANSWER✔✔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.
Question: 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
, Page 2 of 173
B. Complete cord injury
C. Brown-Sequard syndrome
D. Posterior cord syndrome - CORRECT ANSWER✔✔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.
Question: 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. - CORRECT ANSWER✔✔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.
Q;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
, Page 3 of 173
have been linked to HUS?
A. Escherichia coli O157:H7.
B. Clostridium difficile.
C. Rotavirus.
D. Vibrio cholera. - CORRECT ANSWER✔✔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.
Question: Hypertension can be seen in the pediatric population. What is the most common
cause of
secondary hypertension in children?
A. Coarctation of the aorta.
B. Renal disease.
C. Neuroblastomas.
D. Drug toxicity. - CORRECT ANSWER✔✔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
Question: A 10-year-old child is to have a venipuncture done at the femoral site. Which of the
, Page 4 of 173
following anatomic structures is most medial in the inguinal area?
A. Femoral vein.
B. Femoral artery.
C. Femoral nerve.
D. Anterior superior iliac crest. - CORRECT ANSWER✔✔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.
Question: 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.
B. Peer pressure.
C. Body Image.
D. Independence. - CORRECT ANSWER✔✔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.
Question: A 16-year-old female presents to the clinic asking for oral contraceptive pills. Which
