A 2-year-old girl is brought to the emergency department 20 minutes after she accidently ingested insecticide. Her father reports that he was spraying his lawn and
accidentally left the open bottle on the ground. His daughter walked over, picked up the bottle, and started to drink, but then she immediately threw down the bottle. She is
in moderate respiratory distress. Her respirations are I 8/mm and shallow. Pulse oximetry on room air shows an oxygen saturation of 82%. Physical examination shows
copious oral secretions. In addition to securing an airway, the most appropriate immediate step is administration of which of the following medications?
Pralidoxi me
atropine
Succi nylcholi ne
physostigmine
diphenhydramine

  Influenza virus strains are characterized by differing sensitivity to growth inhibition by the weak base ammonium chloride (AC). Influenza A San Francisco (SF) produces
virus yields in AC-treated cells that approximate those in untreated cells, whereas influenza A New York (NY) grows poorly in AC-treated cells. To identify viral genes that
segregate with differences in the sensitivity of these strains to AC, reassortant viruses are isolated by coinfecting cells with both virus strains. The ratios of the growth of the
reassortant viruses in the presence and absence of AC are shown in the table.
Virus Strain AC+IACó Ratio Genome Segment (Protein)
(PA) (HA) (NP) (NA) (Mi/M2)
Parental
NY 0.005 NY NY NY NY NY
SF 0.8 SF SF SF SF SF
Reassortant
NY-SF/i 1.0 SF SF NY NY SF
NY-SF/2 0.8 NY SF NY SF SF
NY-SF/3 0.8 SF SF SF SF NY
NY-SF/4 0.5 NY SF SF NY NY
NY-SF/5 0.4 NY SF SF SF NY
NY-SF/6 0.008 NY NY NY SF SF
NY-SF/7 0.004 SF NY NY SF SF
NY-SF/8 0.002 SF NY NY SF NY
Which of the following viral gene segments segregates with progeny viruses that are resistant to ammonium chloride?
A)HA
B)M1/M2 .
C)NA
D) NP(WRONG)
E)PA

  Yeah i made some stupid mistakes as well, but some questions i had no clue about and some I got had 2 choices and obviously we pick the wrong one always! When are you taking your exam?
But what I have heard about this nbme is that its tough, and has tricky answer choices.
