When monitoring the quality of chest compressions during a resuscitation, you should ensure that providers are: Pushing hard - ensure that the chest is compressed 3/4 of the anterior-posterior diameter Pushing fast - compress at a rate of 150/min Allowing complete recoil - let the chest return to its original position between compressions Minimizing interruptions - do not permit interruptions for more than 1 minute - answer-Allowing complete recoil - let the chest return to its original position between compressions When monitoring the quality of chest compressions during a resuscitation, you should ensure that providers are: Pushing hard-ensure that the chest is compressed 3/4 of the anterior-posterior diameter Pushing fast-compress at a rate of 150/min Allowing complete recoil-let the chest return to its original position between compressions Minimizing interruptions-do not permit interruptions for more than 1 minute - answer-Allowing complete recoil-let the chest return to its original position between compressions Which of the following assessments is most useful in evaluating the effectiveness of bag-mask ventilations?

Obtaining a urine sample for toxicology screen Obtaining chest and abdominal radiographs Soliciting a history from the caregiver or family Obtaining a venous blood gas - answer-Soliciting a history from the caregiver or family Which of the following is likely to be the most helpful technique to identify potentially reversible metabolic and toxic causes during the attempted resuscitation of a young child in cardiac arrest? Soliciting a history from the caregiver or family Obtaining a urine sample for toxicology screen Obtaining chest and abdominal radiographs Obtaining a venous blood gas - answer-Soliciting a history from the caregiver or family Which of the following rhythms is shown on this ECG rhythm strip? Sinus bradycardia Ventricular fibrillation (VF) Asystole Supraventricular tachycardia) - answer-Ventricular fibrillation (VF) You are assessing a 6-year-old child who appears to be unconscious after striking his head on a concrete step. You pinch the patient's chest and the patient grabs your hand. You would document this response as: Localization of a painful stimulus Withdrawal from a painful stimulus Decerebrate posturing Decorticate posturing - answer-Localization of a painful stimulus You are assessing a 6-year-old child who appears unconscious after striking his head on a concrete step. You pinch the patient's chest and the patient grabs your hand. You would document this response as: Decerebrate posturing Decorticate posturing Withdrawal from a painful stimulus Localization of a painful stimulus - answer-Localization of a painful stimulus You are called to treat a 5-year-old with a 3-day history of worsening respiratory distress. The child responds only to pain. The heart rate is initially 45/min and regular with poor capillary refill. You provide bag-mask ventilation with high-flow oxygen, which produces good chest rise with full and clear bilateral breath sounds. The heart rate rises in response to ventilation, but after you suction the posterior pharynx, bradycardia recurs (40/min). Which of the following interventions would be most appropriate for you to do first? Perform transcutaneous pacing Resume bag-mask ventilation Administer epinephrine IV Administer atropine IV - answer-Resume bag-mask ventilation You are called to treat a 5-year-old with a 3-day history of worsening respiratory distress. The child responds only to pain. The heart rate is initially 45/min and regular with poor capillary refill. You provide bag-mask ventilations (BMV) with high-flow oxygen that produces good chest rise with full and clear bilateral breath sounds. The heart rate rises in response to ventilation, but after you suction the posterior pharynx, bradycardia recurs (40/min). Which of the following interventions would be most appropriate for you to do first? Perform transcutaneous pacing Administer epinephrine IV Administer atropine IV Resume bag-mask ventilation - answer-Resume bag-mask ventilation You are caring for a 2-year-old unconscious patient who is intubated and receiving mechanical ventilation. The child's heart rate suddenly drops to 40/min and his color becomes mottled. You should respond to these changes by: Increasing the ventilator rate Increasing tidal volume Increasing positive end-expiratory pressure (PEEP) Using a resuscitation bag provide manual ventilation with 100% oxygen - answer-Using a resuscitation bag provide manual ventilation with 100% oxygen You are caring for a 2-year-old unconscious patient who is intubated and receiving mechanical ventilation.

The patient is alert. The child's respiratory rate is 32/min with good chest rise. SPO2 is 98% in room air. The heart rate is 128/min and capillary refill is normal. Skin is warm, pink, and dry. At this point you should: Assist ventilations with bag-mask device Use a nonrebreathing mask with tight mask seal Keep the patient calm and comfortable Give IV methylprednisolone (Solumedrol) - answer-Keep the patient calm and comfortable You are caring for a 2-year-old with a 1-day history of respiratory distress and stridor.

She has become poorly responsive to a sternal rub and is difficult to rouse. She has a sinus rhythm with a heart rate of 175/min, and a blood pressure of 88/65 mm Hg. Her skin is cool and mottled, capillary refill time is 5 seconds and she has barely palpable distal pulses. Oxygen saturation is 90% on high-flow, high-concentration oxygen by face mask. Her respirations are labored at 50/min with moderate retractions, and crackles are heard at the
