⩥ HESI Hint #3. Answer: Suction only when secretions are present
⩥ HESI Hint #4. Answer: Before drawing a sample for ABGs from the
radial artery, perform the Allen test to assess collateral circulation. The
Allen test ensures collateral circulation to the hand if thrombosis of the
radial artery should follow the puncture.
⩥ Respiratory Failure in Children Causes. Answer: A. Congenital heart
disease. B. Respiratory distress syndrome. C. Infection, sepsis. D.
Neuromuscular diseases. E. Trauma and burns. F. Aspiration. G. Fluid
overload and dehydration. H. Anesthesia and narcotic overdose
⩥ Nursing Assessment: Respiratory Failure in Children. Answer: A.
Very slow or very rapid respiratory rate (tachypnea), dyspnea, apnea,
gasping, stridor. B. Tachycardia. C. Cyanosis, pallor, or mottled color
(connotes deterioration of systemic perfusion). D. Irritability and later,
lethargy (connotes a deteriorating LOC). E. Retractions, nasal flaring,
poor air movement. F. Hypoxemia, hypercapnia, respiratory acidosis. G.
Lab data: values should be evaluated, keeping in mind the percentage of
oxygen the child is receiving.
, ⩥ HESI Hint #5. Answer: Cardinal sings of Acute Respiratory Failure in
children are restlessness, tachypnea, tachycardia, and diaphoresis
⩥ HESI Hint #6. Answer: PCO2>45 or PO2<60 on 50% O2 signifies
respiratory failure. A child in severe distress should be on 100% O2.
⩥ What PO2 value indicates respiratory failure in adults?. Answer: PO2
below 60 mmHg
⩥ What blood value indicates hypercapnia?. Answer: PCO2 above 45
mmHg
⩥ Identify the condition that exists when the PO2 is less than 50 mmHg
and FiO2 is greater than 60%.. Answer: Hypoxemai
⩥ List three symptoms of respiratory failure in adults. Answer:
Dyspnea/tachypnea; intercostal and sternal retractions; cyanosis
⩥ List four common causes of respiratory failure in children. Answer:
