Name the most sophisticated and complex species on planet earth that is also the coolest model organism on which to perform research? 

29.    A respiratory therapist is asked to review a newborn’s history.  The following information is available about the first few minutes after birth:                                           1 minute                    5 minutes        Color                      acrocyanosis                     pink        Heart rate                   70/min                     110/min        Reflex                         grimace                      grimace        Muscle tone       weak movement       active motion        Respiratory rate        20/min                        40/min Which of the following APGAR scores should the therapist expect to see for this infant?         1-minute    5-minutea)    4                  9b)    5                  9c)    4                  10d)    6                 10

The figure below shows the promoter region for a prokaryotic gene, with the binding sites for RNA polymerase in blue and green.  You create a mutant in this promoter by inserting 7 nucleotides (+7-bp) just upstream of the -1 position.  In a few sentences explain what effect this 7-bp insertion in this location would have on (1) the rate of transcription rate, (2) the position of the transcription start site, and (3) the sequence of the RNA transcript. (2 pts.)

In this figure, are the RNA Polymerases moving from left-to-right or from right-to left?   

1.    What is the smallest portion of a child’s airway?a)    Epiglottisb)    Laryngeal openingc)    Cricoid ringd)    Glottis

32.    A respiratory therapist attends the delivery of a 30-week gestational age neonate.  Cyanosis, reduced muscle tone, and diminished respiratory effort are observed after delivery.  The respiratory therapist initiates ventilatory support by bag-mask ventilation for the infant.  There is no chest rise and attempts to reposition the head and ensure a tight mask seal have shown no change.  Which of the following should the respiratory therapist do NEXT?a)    Insert an oropharyngeal airway.b)    Increase the ventilating pressure.c)    Intubate.d)    Suction the mouth then the nose. 

15.    A term infant is born displaying acrocyanosis. What should the therapist do at this time?a)    Administer oxygen to the newborn.b)    Begin resuscitative measures.c)    Institute positive-pressure mechanical ventilation.d)    Do nothing, as this condition is often transient.

39.    A CBG sample is drawn from an intubated 28-week gestational age infant following the administration of surfactant.  When making clinical decisions, a respiratory therapist should consider which of the following measured CBG parameters unreliable?a)    pHb)    PCO2c)    BEd)    PO2

2.    Blood returns to the fetus through which of the following pathways?a)    Umbilical vein, ductus venosus, foreman ovale, umbilical arteryb)    Umbilical artery, ductus arteriosus, foreman ovale, umbilical veinc)    Umbilical artery, foramen ovale, ductus arteriosus, umbilical vein d)    Umbilical vein, ductus arteriosus, foramen ovale, ductus venosus, umbilical artery
