Verified Answers |Actual Complete Exam |Already
Graded A+
6 month old, 6 kg patient has an ABG: pH 7.42, PaCO2 38, PaO2 52, HCO3 25. SIMV 25, Vte 34, f
32, PEEP 5, FIO2 0.6. What vent changes should be made? ✔Correct Answer-Increase PEEP. Pt
PAO2 is low. Improve by increasing PEEP and/or FIO2. PEEP is preferred 1st because FIO2 is
already at 0.6 & a PEEP of 5 is intrinsic, not therapeutic.
Proper uncuffed ETT size for 4 year old? ✔Correct Answer-5.0 ETT (Age in years / 4) + 4. (4/4)
+ 4 = 5.0
You perform a needle thoracostomy on your neonate w/ a suspected "air leak". Which would
indicate that initial treatment was unsuccessful? ✔Correct Answer-A shift of the trachea away
from the needle after procedure.
10 y/o male fell. ALOC upon arrival. EMS states brief LOC & lucidness period before current
decrease in GCS. What type of head trauma is this? ✔Correct Answer-Epidural Bleed
A diving accident result in a patient having no lower extremity movement, however they can
Flex their arms but not extend them where is the fracture? ✔Correct Answer-C7 *Pearls* C3-
C5 controls the phrenic nerve & diaphragm. C5-C6 control elbow flexion. C7 controls wrist and
elbow extension.
A 1 year old has left upper lobe PNA. BP 70/36, HR 138, RR 48, SpO2 87% T 102.1. ABG 7.20,
PaCO2 68, PAO2 65%. The presentation will result in what changes (Shift)? ✔Correct Answer-
Right shift due to decreased SaO2/pH and increase CO2, Temp.
If the IABP migrates upward, what is likely to be affected? ✔Correct Answer-Left Radial. An
intra aortic balloon pump is positioned so the tip is approximately 1 to 2 cm below the origin of
the left subclavian artery and above the renal arteries. If the balloon migrates up and blocks the
left subclavian it will result in a loss of perfusion to the left arm and left radial. If it migrates
down it will cause loss of renal perfusion and urine output will decrease or stop altogether.
Check pulses and you're an output every 15 minutes.
A neonate w/ choanal atresia would have difficulty w/ all of the following except? A) Sleeping B)
Breathing C) Feeding D) Diuresis ✔Correct Answer-D) Diuresis, Choanal atresia is narrowing of
nasal airway. Results in difficulty breathing and sleeping. Requires surgical intervention.
,Neonate experiencing repetitive motion of bicycling and lip smacking. What type of seizure do
you suspect? ✔Correct Answer-Subtle. Repetitive mouth/tongue movements, bicycling, eye
deviation/blinking.
When checking a Pplat, any pressure above _______ can cause ventilator lung injury &
barotrauma? ✔Correct Answer-30 mmHg
If a patient receiving an IABP urine output stopped in transport. What likely happened?
✔Correct Answer-Renal artery occlusion secondary to balloon downward migration.
Primary trigger for IABP operations is? ✔Correct Answer-ECG waveform
Patient has a low central venous pressure (CVP), low systemic vascular resistance (SVR) &
adequate cardiac index (CI). What is the diagnosis? ✔Correct Answer-Neurogenic shock -->
which results in a loss of the sympathetic tone, leaving parasympathetic tone only. Loss of
sympathetic tone results in loss of vascular tone, associated with low central venous pressure
and low systemic vascular resistance. Cardiac index often remains unchanged
Dicrotic notch represents what on an A-Line? ✔Correct Answer-Aortic valve closure. Closes
the same time as pulmonic valve. Brings coronary reperfusion.
Dicrotic notch represents what on pulmonary artery waveform? ✔Correct Answer-Pulmonic
valve closure. Closes the same time as the aortic valve.
A patient in initial shock state most likely has which acid-base disorder? ✔Correct Answer-
Respiratory alkalosis. Initial response to stress is increased RR, followed by increase HR. Increase
RR leads to respiratory alkalosis in early shock.
13 y/o insulin dependent diabetes has labs: Na: 150, Cl 103, glucose 504, WBC 12.3. Bands 14%.
What is the most likely cause of the patient DKA state. ✔Correct Answer-Acute infection.
Infection is the most common cause of diabetic ketoacidosis and Insulin dependent patients due
to the increased need for insulin. Inpatients with increased O2 demand the liver
secretesincrease amounts of glycogen for ATP production.
A 12 year old current pH 7.52. Previous pH was 7.41 & their potassium was 4.7 mEq/L. What is
the expected new K+. ✔Correct Answer-4.1 mEq/L. For every 0.10 in pH, there is a
corresponding decrease in potassium by 0.6.
VFR weather minimum must meet national standard or exceed FAA 14 CFR part 135.203 part
135.205 as followed? ✔Correct Answer-Ceiling > or equal to 1000 feet. Visibility greater than
or equal to 2 miles
, Emergency procedures (i.e. Fire, depressurization, IMC) ✔Correct Answer-Pilot announces
emergency, maintain sterile cockpit, assist pilot PRN, Prep for emergency landing, secure
equipment, shut of oxygen and inverter.
Landing zone operations for HAZMAT scenes? ✔Correct Answer-Safe zone uphill, upward and
far enough from scene to prevent rotor wash from spreading HAZMAT materials. Do not fly
above HAZMAT scene.
What is sterile cockpit? ✔Correct Answer-Restricts all non essential communication during
critical phases of flight. Report concerns of safety to pilot, this warrants talking.
Contact/point of reference during crash? ✔Correct Answer-Keep point of contact inside cabin
to maintain spatial orientation in case aircraft comes to rest on its side or inverted.
Recommendations for barotitis media in flight? ✔Correct Answer-Reascent and then slow
controlled descent is most appropriate. Analgesics will help w/ pain but will not treat the
causative pathology.
With time of useful consciousness, what happens to the pulmonary system? ✔Correct
Answer-On decompression > 33,000 feet, an oxygen reversal takes place in alveoli, caused by
higher PaO2 within the pulmonary capillaries. This depletes oxygen reserves in blood. Forced
exhalation can decrease this time.
Cause of hypoxic hypoxia @ altitude? ✔Correct Answer-With an increase in altitude, there is
reduction in PaO2 causing inadequate gas exchange.
Concerns of a patient w/ elevated ICP in flight ✔Correct Answer-Increase in altitude may
cause worsening neurological status
Best position for a patient during endotracheal intubation ✔Correct Answer-HOB @ 20- 45
degrees. Helps improve oxygenation, increases 1st pass success & decreases hypoxemia.
Concerns w/ airway management in a patient greater than 35 BMI? ✔Correct Answer-More
difficult intubation. Anatomic & physiologic challenges w/ bariatric patient. Increased chest wall
& airway resistance. Abdominal pressure and subcutaneous tissue. Decreased lung capacity
which results in decrease vital capacity.
Risks with assist control? ✔Correct Answer-Breath stacking and auto PEEP
1st step for tracheostomy pt. w/ respiratory distress? ✔Correct Answer-Remove inner
cannula. If ventilation is still unsuccessful remove tracheostomy and replace with ETT. If
intubation is not possible initiate BVM over mouth & nose while covering stoma.
