48. Which statement about tachycardia is NOT correct?  A heart rate of 175 bpm is within normal range for a child up to two A normal heart rate for an infant may be twice as fast as normal heart rate for an older child.  Sinus tachycardia IS commonly a dangerous rhythm that can quickly deteriorate to cardiac arrest. Tachycardia may be a normal, non-dangerous. heart rate in response to stress Ie anxiety.49. What is the primary therapy for hypovolemic shock?Fluid resuscitationCorrection of metabolic derangementsVasopressorsAntibiotics50. Pulse oximetry is monitored during post-resuscitation care to:Monitor hypoglycemia Optimize Ventilation and circulation Stabilize Blood pressure Monitor hypovolemia

Sinus tachycardia is characterized by a heart rate greater than:*1 pointa) 60 beats per minuteb) 100 beats per minutec) 120 beats per minuted) 160 beats per minute

Serious signs and symptoms of unstable tachycardia are usually NOT seen with ventricular rates less than:Question 57Answera.200 beats per minuteb.150 beats per minutec.120 beats per minuted.250 beats per minute

20. Which statement is correct concerning neurological assessment during post-resuscitation management?Dilated unresponsive pupils, hypertension, bradycardia, respiratory irregularities, or apnea may indicate cerebrat hemiationProlonged hypoventilation is suggested for imminent cerebral herniation Hypothermia should be elicty avoided. Seizures should not be treated21. Which statement concerning ventricular tachycardia is NOT correct?Ventricular tachycardia is very common in childrenVentricular tachycardia most often occurs in children with underlying cardiac disease or in children who have had heart surgeryVentricular tachycardia can result from electrolyte disturbabcesVentricular tachvcardia is a wide complex rhythm

44. Pharmacologic agents that may be used in the treatment of shock include all of the following EXCEPT:NorepinephrineDiltazemDopamineMilrinone45. Which of the following is a wide complex tachycardia?Sinus tachycardiaAtrial flutterSupraventricular tachycardiaVentricular tachycardia46. Which statement about dexamethasone is NOT correct?Dexamethasone is indicated for mild to severe croup.Dexamethasone reduces the number and activation of lymphocytes, eosinophils, mast cells, and macrophages.Dexamethasone commonly causes hypotension.Dexamethasone is a corticosteroid47. The first management step in cardiac arrest is to:Suppress or treat arrhythmiasIncrease coronary and cerebral perfusion pressures and blood flowStimulate more forceful myocardial contractilityBegin high-quality CPR

18. All of the following are signs of cardiorespiratory distress EXCEPT:TachypneaIrregular heart rhythm FatigueJaundice19. Which statement best describes cardiogenic shock?Individuals in cardiogenic shock have normal peripheral pulses and blood pressure.Increased blood pressure with wide pulse pressures always indicates cardiogenic shock.Increased myocardial dysfunction indicates cardiogenic shock and deteriorating condition.Aggressive fluid therapy is always indicated for cardiogenic shock.
