A 8-year-old boy is agitated and leaning forward on the bed in obvious respiratory distress. The patient is speaking in short phrases and tells you that he has asthma but does not carry an inhaler. He has nasal flaring, severe suprasternal and intercostal retractions, and decreased air movement with prolonged expiratory time and wheezing. You administer 100% oxygen by a nonrebreathing mask. His SpO2 is 92%. Which medication do you prepare to give to this patient?

A 12-year-old suddenly collapses while playing sports.  He is unresponsive and not breathing.  Emergency response is activated.  The child has no pulse, and CPR is initiated.  An AED arrives.  What is the most appropriate next intervention?

Faden and Beauchamp suggest that there is more than one type of “informed consent”: sense1 and sense2.  Which of the following claims is not true of these senses of informed consent?

Which of the following is most likely to produce a prolonged expiratory phase and wheezing?

What abnormaality is most likely to be present in children with acute respiratory distress caused by lung tissue disease?

You are alone and witness a child suddenly collapse. There is no suspected head or neck injury. A colleague responded to your shout for help and is activating the emergency response system and is retrieving the resuscitation equipment, including a defibrillator. After delivering 30 compressions, what would be your next action?

Which of the following is not a condition of informed consent?

Which measure of central tendency would be used in economics where one of the topics studied is income of Americans?

Use this information to answer the next two questions. The rates of movement of various molecules across the membrane of a eukaryotic cell were measured. The cells were then poisoned with cyanide and allowed to die, and the rates of the molecules movement across the membrane were measured again. The data are summarized in this table. Molecule tested Rate before death(mean ± standard deviation) Rate after death(mean ± standard deviation) Number of samples Potassium 35 ± 30 976 ± 88 6 Water 30 ± 28 842 ± 83 3 Carbon dioxide 1543 ± 176 1499 ± 165 9 (“Mean ± standard deviation” means that the first number represents the mean of the samples plus or minus the second number, which represents the standard deviation for those samples. This gives a range for the data, much like the error bars on a graph.)

You and another rescuer begin CPR. Your colleague begins compressions, and you notice that the compression rate is too slow. What should you say to offer constructive feedback?
