An 8-year-old child presents with a history of vomiting and diarrhea.  The child has the following vital signs: heart rate 168/min., respiratory rate 15/min, blood pressure 90/60 mm Hg, and a tempeerature of 98.6F (37C).  The child’s capillary refill time is 4 seconds.  After 2 IV boluses of normal saline (20mL/kg each), the child’s vital signs are now as follows: heart rate 130/min., respiratory rate 16/min., blood pressure 94/62 mm Hg., capillary refill is 2 seconds, and the tempeerature 98.6F (37C).  The child’s urine output is 1 to 2 ml/kg in the past hour.  The child is lethargic.  What diagnostic tests or information should be obtained first?

A child presents with severe respiratory distress, urticaria, stridor, and tachycardia about 10 minutes after eating peanuts.  What is the most appropriate initial medication for this child?

A 3-month-old infant with bronchlolitis is suctioned to remove upper airway secretions.  The infant’s rate rate decreases from 155/min to 65/min. as shown below The infant remains alert, with easily palpable pulses.  Capillary refill time is 1 second.  What is the most appropriate initial intervention?

A 6-month-old is unresponsive and not breathing.  What is the maximum time that should be spent trying to palpate the pulse before starting CPR?

A 3-year-old unresponsive, apneic child is brought to the emergency department. EMS personnel report that the child became unresponsive as they arrived at the hospital. The child is receiving CPR with bag-mask ventilation. The rhythm shown on the cardiac monitor is ventricular fibrillation. A biphasic manual defibrillator is present. You quickly use the length from head to heel of the child on a color-coded length-based resuscitation tape to estimate the approximate weight as 15 kg. Which therapy is most appropriate for this child at this time? Choose the correct option and select submit.

A 7-year-old presents with a narrow-complex supraventricular tachycardia, lethargy, and poor perfusion.  Pulses are weak and thready.  Vascular access cannot be established.  What is the most appropriate intervention?

You find an infant who is unresponsive, is not breathing, and does not have a pulse. You shout for nearby help, but no one arrives. What action should you take next?

A 5-year-old child presents with lethary, increased work of breathing, and pale in color.  The primary assessment reveals that the airway is open and the respiratory rate is 30/min. with crackles heard on auscultation.  The cardiac monitor show sinus tachycardia at a rate of 165/min.  The pulse oximetry displays an oxygen saturation of 95% and a pulse rate of 93/min.  On the basis of this information, which of the following provides the best interpretation of the oxygen saturation of 95% by pulse oximetry?
