You are transporting a traumatic patient who has been in the Trauma ICU
with significant injuries for 1 week. He has not developed sepsis with the
following VS:
BP: 88/55
,P: 120 Sinus tach without ectopy
RR: 10
SpO2: 100%
Temperature: 102.1F
ABGs
pH: 7.1
PaCO2: 50mmHg
PaO2: 340 mmHg
HCO3: 30mEq/L
What would you expect with this patient's O2 Hemoglobin dissociation
curve? - 🧠ANSWER ✔✔The curve will be shifted right
You are intubating a 54 year old female who is 5'2" and weighs 235lbs.
While preforming a mallampati assessment, you notice her soft palate and
major part of uvula present. You could classify her as a class: - 🧠ANSWER
✔✔II
,Structures seen with Class I Mallampati assessment - 🧠ANSWER ✔✔Soft
palete, uvula, fauces, pillars visible
Structures seen with Class II Mallampati assessment - 🧠ANSWER ✔✔Soft
Palate, major part of uvula, fauces visible
Structures seen with Class III Mallampati assessment - 🧠ANSWER ✔✔Soft
palate, base of uvula visible
Structures seen with Class IV Mallampati assessment - 🧠ANSWER
✔✔Only hard palate visible
What can cause a left shift in the oxyhemoglobin dissociation curve?
ARDS
A pt. who received mass transfusion
Respiratory Acidosis
Sepsis - 🧠ANSWER ✔✔A patient who received mass transfusion
Would shift left due to increased oxygen carrying. ARDS, Respiratory
acidosis, and sepsis all are associated with acidosis, lower pH, higher
levels of CO2, which would cause a right shift

, When it comes to making ATP during aerobic respiration, why is oxygen
necessary? - 🧠ANSWER ✔✔Oxygen is the final electron acceptor in the
electron transport chain
High-energy electrons go through the electron transport chain in a series of
exe3rgonic redox reactions. Ultimately used to produce ATP.
