PALS study guide questions and answers 100% verified. If the pulse rate on the pulse ox differs from the EKG monitor the O2 saturation reading is - correct answer. not reliable, the child needs oxygen in spite of possible O2 saturation above 94%. A BP reading of what in a neonate is considered hypotension when? - correct answer. of less than 60 systolic What airway obstruction is characterized by tachypnea, increased respiratory effort, cough, stridor, and poor air oxygenation? - correct answer. upper airway obstruction Typical signs and symptoms of upper airway obstruction occur predomintly during the what phase of respiratory cycle? - correct answer. inspiratory phase This is an abnormal breathing pattern that produces inadequate respiratory rate or effort that is usually associated with neurological disorders such as brain tumors, seizures, head injury, hydrocephalus or neuromuscular disease? - correct answer. disordered control of breathing Increased work of breathing and tachypnea in a toddler may be classified as what? - correct answer. as respiratory distress rather than failure Moderate stridor and retractions along with a seal bark cough in a toddler may be best managed by administration of what? - correct answer. nebulizer epi The child who presents with severe respiratory distress and signs of anaphylaxis must be treated promptly with what? - correct answer. IM/IV epi/corticosteroids as well as nebulized albuterol. Defined as a critical condition that results from inadequate tissue delivery of O2 and nutrients to meet tissue metabolic demands? - correct answer. shock Infants have tiny hearts and increase their cardiac output primarily by what? - correct answer. increasing heart rate In order to recognize shock early, the health care provider must recognize signs of compensated shock such as what? - correct answer. tachycardia, increased stroke volume, and increased cardiac contractility Increased systemic vascular resistance or vasoconstriction may be recognized clinically in the child who has what? - correct answer. cold extremities, poorly palpable peripheral pulses, delated capillary refill time Stroke volume may be maintained in early shock by increased what? - correct answer. increased contraction and venoconstriction which increases venous return to the heart, thus increasing preload. Anxiety, tachycardia, delayed capillary refill time, and a normal BP in a young child indicate what type of shock? - correct answer. compensated shock Elevated temperature, lethargy, tachycardia, tachypnea may be associated with what type of shock? - correct answer. distributive shock The child who is febrile, lethargic, tachycardia, apthypneic, hypotensive, with a delayed capillary refill time needs immediate IV/IO access and administration of what? - correct answer. fluid bolus such as normal saline or ringers lactate at 20 ml/kg over 5-10 minutes. The appropriate fluid bolus for shock resuscitation in the child with a normal heart is what? - correct answer. 20 ml/kg of isotonic crystalloid (normal saline) In a child with serious signs and symptoms of hypovolemic shock, the quickest and best way to establish vascular access is via the what route? - correct answer. IO route the correct intervention when a child presents with severe respiratory distress, low oxygen saturation, absent breath sounds on the right side of the chest, and signs of obstructive shock is what - correct answer. needle decompression of the right chest when an infants heart rate falls to 70 bpm when suctioned, the health care provider must administer what - correct answer. oxygen and ensure adequate oxygenation the correct treatment for a child who suddenly develops a heart rate of 240 bpm and has palpitations and dizziness is what - correct answer. vagal maneuvers the correct way to perform vagal maneuvers on an infant with SVT and adequate perfusion is what - correct answer. ice on the face over the upper half the correct intervention to perform when a child presents with lethargy, SVT, and signs and symptoms of inadequate perfusion is what - correct answer. cardioversion at 0.5-1 J/kg you are caring for an infant who is unresponsive and not breathing, what is the maximum amount of time you should spend palpating for a pulse - correct answer. less than 10 seconds where is the appropriate place to palpate a pulse in an infant - correct answer. brachial an unresponsive child presents with a rhythm that resembles sinus bradycardia but a rhythm is not accompanied by a pulse, he must be treated with what algorithm - correct answer. pulseless electrical activity when a child is found in cardiac arrest, high quality CPR is initiated. when a cardiac monitor reveals ventricular fibrillation, the appropriate intervention is what - correct answer. defib at a rate of 2 J/kg an infant presents with CPR in progress. the cardiac monitor shows an organized rhythm with a rate of 70 without a pulse. what is the correct intervention? - correct answer. administer epi the most important drug to administer to a child in cardiac arrest while CPR is being performed is what - correct answer. epi at a dose of .01 mg/kg in a child who achieves ROSC, the appropriate target range for oxygen saturation is what - correct answer. 94 to 99% shock caused by inadequate blood volume - correct answer. hypovolemic shock shock caused by inappropriate distribution of blood volume or flow - correct answer. distributive shock shock caused by impaired cardiac contractility - correct answer. cardiogenic shock shock caused by obstructed blood flow - correct answer. obstructive shock this presents when the BP is normal but there are other signs of inadequate tissue perfusion - correct answer. compensated shock what is a key sign of hypotensive shock - correct answer. decreased level of consciousness
