TNCC 8th Edition Questions with Complete
Solutions
Describe the measurement of an NPA Measure from the tip of the patient's nose to the tip
of the patients earlobe.
Measurement of an OPA Place the proximal end or flange of the airway adjunct at the
corner of the mouth to the tip of the mandibular angle.
True or false: NPAs and OPAs are definitive airways. False. When placing one of these?
One should consider the potential need for a definitive airway.
Name the three ways to confirm ETT placement Placement of a CO2 monitoring device,
Assessing for equal chest rise and fall, and listening at the epigastrium and four lung fields for
equal breath sounds.
When capnography measurement reads greater than 45MMHG, the nurse should consider
increasing or decreasing the ventilation rate? Increasing the ventilation rate. Doing so
would allow the patient to blow off retained CO2.
, When capnography measurement reads less than 35MMHG, the nurse should consider increasing
or decreasing the ventilation rate? Decreasing the ventilation rate. By doing so, the nurse
allows the patient to retain CO2.
What are the three stages of shock Compensated, decompensated or progressive, and
irreversible.
What are the signs of compensated shock? Anxiety, confusion, restlessness, increased
respiratory rate, narrowing pulse pressure were diastolic increases yet systolic remains
unchanged, tachycardia with bounding pulses, and decreased urinary output
What are the signs and symptoms of decompensated shock? Decreased level of
consciousness, hypertension, narrow pulse pressure, tachycardia with weak pulses, tachypnea,
skin that is cool clammy and cyanotic, base access outside the normal range, and serum lactate
levels greater than two to 4MMOL/L.
What are the signs and symptoms of irreversible shock? Obtunded stuporous or comatose
state, marked hypertension and heart failure, bradycardia with possible dysrhythmias, decreased
and shallow respiratory rate, pale cool and clammy skin, kidney liver and other organ failure,
