NBRC TMC ACTUAL PRACTICE QUESTIONS WITH ACCURATE SOLUTIONS ALREADY
GRADED A+
Which of the following is needed to calculate alveolar oxygen tension?
A. VD/VT, PAO2
B. BP and FiO2
C. PetCO2 and PaO2
D. QS/QT, deadspace
B.
Barometric pressure, FiO2, and PaO2 are all included in the formula (BP stands for
barometric pressure)
While assessing a patient receiving positive pressure ventilation with a Servo adult
ventilator, the therapist notes a sudden low return volume alarm begins sounding. Which of
the following could be the cause?
A. pulmonary embolism
B. excess condensate in the ventilator circuit
C. bronchopleural fistula
D. ARDS
C.
The solution to this problem is to determine which answer could lead to a low-pressure
alarm. Excess condensate in the ventilator circuit and adult respiratory distress syndrome
would more likely lead to high-pressure alarms. A pulmonary embolism is not related to
any particular alarm. That leaves a bronchopleral fistula as the only possible cause.
,When considering appropriate staffing levels and proper care of patients, a respiratory
therapy supervisor would include which of the following
A. frequency of declined therapy
B. Individual skills of staff members
C. previously missed therapy
D. staff member preference
B.
When planning appropriate staffing levels for patient care, frequency of therapy, type of
therapy ordered, and the individual skills of the staff are all important considerations.
Department budgetary goals should not affect staffing.
A respiratory therapist is preparing a patient who will be transferred home and will be
ventilator dependent during the night. Which of the following devices would be most
helpful to ensure adequate hydration of the patient's airway during the night?
A. Large volume nebulizer
B. Cascade humidifier
C. Heat moisture exchanger (HME)
D. Heated wire ventilator circuit with water traps
C.
An HME device is intended for short-term use. Patients who are ventilator-dependent
during the night may use this device.
After noting profuse bubbling in the water-seal chamber of a disposable three-chamber
chest drainage system, the RT places a clamp on the chest tube proximal to the patient. In
doing so, the bubbling dissipates and stops. What can be concluded?
,A. The leak must be in the tubing leading to the chest drainage system
B. Suction pressure at the wall is excessive
C. The patient may have perforation in lung tissue
D. Leaking is most likely occurring inside the three-chamber system
C.
A 22-year-old, 6-ft, 3-in Caucasian male is in the ER for sudden, unexplained onset of
tachypnea. Chest radiography shows hyper lucency in the left chest, dominated by a large
dark area over the entire left lung field. The physican decides to install a chest tube
drainage system and asks for your recommendation on chest tube placement. You will
suggest which of the following?
A. Right side, mid-axillary line, 5th intercostal space
B. Right side, left side, 4th intercostal space, mid-clavicular line
C. Left side, mid-axillary line, 5th intercostal space
D. Left side, 2nd intercostal space, mid-clavicular line
D.
In a patient with a partial pneumothorax, what percent of collapse is the threshold that
indicates the need for chest tube insertion?
A. 50%
B. 20%
C. 10%
D. 15%
, B.
By what route is Xolair (omalizumab) administered?
A. Subcutaneously
B. Aerosolized
C. IV
D. Intra-muscular
A.
How many milliliters of aerosolized medication should be prepared to deliver 30 mg of that
same drug if the strength is 1.5%
A. 2.0 mL
B. 4.5 mL
C. 20 mL
D. 45 mL
A.
Strength of 1.5% x 10 = 15 mg/mL
30 mg / 15 mg/mL = 2.0 mL
An aerosolized bronchodilator is being administered to a patient. The dose is 5.0 mL and
the drug strength is 2.0%. How many milligrams of the drug will be administered?
