1. A 12-year-old child being evaluated in the pediatric intensive care unit displays the following ECG waveform. The team interprets this as which arrhythmia?: second degree
2. Laboratory tests are ordered for a child who has been vomiting for 3 days and is diaphoretic, tachypneic, lethargic and pale. Which test would the provider use to determine the adequacy of oxygen delivery?: Lactate
3. A 9-year-old patient is presenting with decreased breath sounds, brady- cardia, slowed respiratory rate and a low O2 saturation level. The provider interprets these findings as indicating which condition?: Respiratory failure.
Answer:
The answers provided are partially correct.
- The ECG waveform provided doesn’t provide enough information to accurately diagnose an arrhythmia. A 12-lead ECG is usually required to diagnose arrhythmias.
- While lactate levels can be used as a marker of tissue hypoxia and as an indicator of poor oxygen delivery, other tests such as arterial blood gas (ABG) analysis, complete blood count (CBC), electrolyte levels, and cardiac enzymes might also be ordered to help diagnose the underlying cause of the child’s symptoms.
- The symptoms described are consistent with respiratory failure, which is a life-threatening condition that occurs when the respiratory system fails to provide an adequate amount of oxygen to the body or remove enough carbon dioxide from the body. However, further evaluation and tests are needed to determine the specific cause and severity of the respiratory failure.
