Are there open wounds or deformities in the chest? What's the depth, pattern, and rate of respirations? Is there increased work of breathing? Are breath sounds present and equal? 3 ways to assess ETT placement Correct Answer: 1. Apply end tidal, assess CO2 after 5-6 breaths 2. Assess for symmetrical chest wall rise and fall 3. Auscultation over the epigastrium for gurgling and bilateral breath sounds. What do you document after placing an ETT? Correct Answer: ETT placement at teeth or gums Situations that require a definitive airway Correct Answer: GCS 8 or less Apnea Inhalation injury Increased risk of aspiration Anticipate decreased neuro status Severe maxo fractures Laryngeal/tracheal injury Where do you listen for breath sounds? Correct Answer: 2nd intercostal space at midclavicular line and 5th intercostal space at anterior axillary line King airway Correct Answer: A multidimensional esophageal airway that traps the glottis opening between an esophageal cuff and an oropharyngeal cuff 3 things to assess for circulation Correct Answer: Palpate central pulse Assess (again) for external hemorrhage Inspect and palpate skin for color, temp, and moisture.

Correct Answer: Fluids with dextrose to prevent hypoglycemia How much fluid do you give a kid? Correct Answer: 20mL/kg What assessment finding gives concern for severe brain injury? Correct Answer: Bulging fontanels Parkland formula Correct Answer: 3mL x the weight in kg x % TBSA = the fluid to go over 24 hours How do you give the fluid over 24 hours in parkland formula? Correct Answer: First half over 8 hours and second half over 16 hours Normal baseline FHR Correct Answer: 120-160 What does Kleihaver-Betke test for? Correct Answer: Tests for fetal RBCs I. Maternal circulation, which is abnormal and could indicate fetomaternal hemorrhage has occurred Symptoms of abruptly placentae Correct Answer: Dark red bleeding, sudden sharp abdominal pain, "board-like" uterus, increased FHR
