While performing a routine ventilator check on a patient in the ICU, the respiratory
therapist notes that the patient's cardiac monitor shows ventricular tachycardia at a
rate of 165. The therapist determines the presence of a carotid pulse, although the
patient is hypotensive and unresponsive. Which of the following should the
respiratory therapist recommend?
A. prepare for defibrillation
B. administer a precordial thump
C. prepare for synchronized cardioversion
D. administer 1mg/kg of lidocaine
Give this one a try later!
Answer is C.
defribrillation is for pulseless tachycardia. Precordial thump is a punch also
needs to be pulsless. Synchronized cardioversion low watted shock non
lethal and used with patients with a pulse. Lidocaine is for PVCs.
,A 28-week gestational age infant with severe respiratory distress syndrome is being
mechanically ventilated in the PC, SIMV mode at the following settings:
Flow rate: 6 L/min
Set rate: 32 br/min.
PIP: 28 cmH2O
FIO2: 0.70
PEEP: 5 cm H2O
I time: 0.8 seconds
Umbilical arterial blood gas results reveal:
pH: 7.40
PCO2: 39 torr
PO2: 42 torr
HCO3-: 23 mEq/L
Based on the above information, the respiratory therapist should change the
A. I time to 1.0 second.
B. PEEP to 7 cm H2O.
C. FIO2 to 0.75.
D. PIP to 30 cm H2O.

Ventilation is good on baby, PO2 is bad (less than 60), so we have an
oxygenation problem. Baby is already on high level of oxygen and they are
already on PEEP therapy, but they are still shunting (they are on 70% FiO2
and still bad oxygenation with good ventilation) so inch up the PEEP (never
above 8),
so ANSWER is B, PEEP to 7 cm H2O.

Question 6 of 15 - Patients airway pressures are decreasing, lungs are
improving. Since it's the patients airway pressure that is decreasing, we
should readjust the low pressure alarm, so ANSWER is B, low pressure
alarm.
A 5' 10", 80 kg (176 lbs) male patient with multiple trauma from a motorcycle accident
has developed ARDS and is being ventilated at the following settings:
Mode: VC, SIMV
VT: 500 mL
Set Rate: 14 br/min.
FIO2: 0.60
PEEP: 12 cm H2O
Arterial blood gas results reveal:
pH: 7.35
PaO2: 72 torr
PaCO2: 44 torr
SpO2: 93%
The patient is conscious and pulling on the IV lines and ventilator tubing. At this time,
the respiratory therapist should recommend
A. changing to assist/control mode.
B. restraining the patient.
C. increasing the set rate to 16 br/min.
D. sedating the patient.
Give this one a try later!
D, Sedate the patient (if nothing in their blood gas is causing their behavior
and they are just agitated, just sedate them to calm them down); Changing
to assist/control mode won't do anyting about patients agitation;
Restraining patient won't help agitation and might cause them to become
more violent; Increasing the set rate to 16/br min. won't do anything and
this isn't a good time to change settings.
, In preparing to perform a cardiopulmonary stress test on a 60-year-old man, the
respiratory therapist must determine the target heart rate range for the patient. What
is the patient's maximum heart rate?
A. 130 beats/minute
B. 160 beats/minute
C. 190 beats/minute
D. 220 beats/minute
Give this one a try later!
heart rate is 220, minus patients age so...
220-60. So answer is B.
Methacholine Challenge Test
Tensilon Challenge Test
Give this one a try later!
Methacholine Challenge Test is a pulmonary function test used to check the
reactivity of a patients airways, it will induce bronchospasm;
Tensilon Challenge Test is specifically for Myasthenia Gravis, it helps them
breath right away but only lasts a few minutes
A patient is observed to have an increased respiratory rate and depth of breathing.
Their breath has a fruit-like aroma. This would most likely be associated with:
A. head trauma
B. metabolic acidosis
C. drug overdose
D. chronic obstructive lung disease
