To ensure adequate surgical anesthesia for a cesarean delivery performed under spinal anesthesia, sensory blockade must reach which dermatomal level?
T4
Narrowest part of pediatric airway
cricoid cartilage
A 100 kg patient has successfully separated from cardiopulmonary bypass following cardiac surgery. The surgical team requests reversal of systemic anticoagulation. The patient received a total of 30,000 units of heparin during bypass.
How much protamine should be administered to reverse the heparin effect?
300 mg
A 1:200,000 mixture of epi corresponds with what concentration in mcg/mL
5 mcg/mL
Max FiO2 that can be delivered by a nasal cannula
0.45
A patient at 36 weeks’ gestation presents with new-onset hypertension. Blood pressure is 156/98 mm Hg. Urinalysis shows 2+ protein, and platelet count and liver enzymes are normal.
Which of the following is the most likely diagnosis?
Preeclampsia
Level of larynx in peds
C3/C4
Primary determinant of LA potency
lipid solubility
SSEP waveform changes most consistent with spinal cord ischemia (amplitude and latency)
decreased amplitude and increased latency
You are called to the ICU to assist with airway management for a 3-year-old child with a high fever, inspiratory stridor, tachypnea, and marked sternal retractions. The patient is sitting upright, leaning forward, drooling, and appears anxious.
Which of the following is the most likely cause of this presentation?
Epiglottitis
APGAR stands for
Appearance, Pulse, Grimace, Activity, Respiration
A 32-year-old patient undergoes emergency cesarean delivery for placental abruption under general anesthesia. Near the end of the case, the patient suddenly develops profound hypotension, severe hypoxemia, and markedly increased peak inspiratory pressures. The surgeon reports diffuse oozing from the surgical field.
Which of the following is the most likely cause of this acute deterioration?
Amniotic Fluid Embolism
An 11-year-old patient (weight 40 kg) presents for revision posterior spinal fusion for scoliosis. Significant blood loss is anticipated. The surgical team requests that red blood cell transfusion be initiated if the hematocrit decreases below 24%. The current hematocrit is 30%.
What is the allowable blood loss for this case before transfusion is indicated?
560 mL
Allowable blood loss (ABL) is calculated as: estimated blood volume (EBV) × (starting hematocrit − lowest acceptable hematocrit) ÷ starting hematocrit. Standard EBV values by age group are approximately:
Using an EBV of 70 mL/kg for this 11-year-old child gives a total blood volume of 2,800 mL, and an ABL of 2,800 × (30 − 24) ÷ 30 = 560 mL.
