NBRC THERAPIST FORUM A AND B 2020 TESTBANK LATEST
WITH QUESTIONS AND VERIFIED ANSWERS

PATIENT ASSESSMENT:
A 2-year old child enters the emergency room. The mother states that the
child was playing with friends and developed violent coughing and unilateral
wheezing. Physical examination reveals a hyperresonant percussion note on
the left and resonant percussion on the right. Inspiratory and expiratory
chest films indicate air trapping with no foreign bodies "noted." The
respiratory therapist should suspect the child has.
a.pneumothorax
b.orthopnea
c.aspirated a foreign object
d.tachyphylaxis - Unilateral wheezing indicates aspirated object and fact
that the child was playing with friends causes you to believe the child
inhaled a small toy or something, hyperresonant percussion indicates air
trapping, so you are thinking foreign object but x-ray says no foreign bodies
"noted." Just because it says "noted" does not mean something is not there,
it just means it could not be seen on the xray, also if the child had swallowed
a small plastic toy, "plastic" does not show up on xrays (radiolucent). The
ANSWER is C
A patient is admitted to the ICU complaining of nausea and chest pain. A
nasogastric tube has been inserted to help relieve the nausea. The patient
was started on Lasix and nitroglycerin. Which of the following should be
monitored to closely identify side effects at this time.
a. Cardiac enzymes
b. Serum electrolytes
c. Arterial blood gases
d. Digitalis levels - Since the patient received Lasix and nasogastric tube,
they are losing fluids, and a side effect of fluid loss is a decrease in
electrolytes, so ANSWER is B (there isn't enough evidence of heart attack to
justify cardiac enzymes, also they are used to confirm a heart attack).
Which of the following will determine aortic pulse pressure.
a. systolic + systolic + diastolic/3
b. diastolic + pulse pressure/3
c. systolic pressure - diastolic pressure
d. stroke volume x heart rate x 10. - Aortic pulse pressure is just the
difference between systolic and diastolic pressure, so ANSWER is C
A 32-week gestational age infant is receiving mechanical ventilation for
hyaline membrane disease. The patient required a chest tube for a
persistent pneumothorax. Two days later the chest radiograph reveals
bilateral radiolucency, midline mediastinum, and the right hemidiaphragm
slightly elevated. This would indicate
A. atelectasis.
B. bronchopulmonary dysplasia.
C. fluid overload.
D. resolution of a pneumothorax. - bilateral means both sides, radiolucency
refers to dark, midline mediastinum is right where is should be, the right
hemidiaphragm slightly elevated is normal; so this actually indicates
everything is normal. With atelectasis we would see patchy infiltrates, loss
of volume, with bronchopulmonary dysplasia it would look similar to ARDS,
with fluid overload you would see pattern similar to butterfly or batwing
similar to pulmonary edema, so the best
ANSWER is D and the pneumothorax has resolved.
All the following could cause capnography to go from 3 6 to 30 EXCEPT:
A. Endotracheal tube positioned in the right mainstream bronchus
B. Hyperventilation
C. pulmonary emboli
D. Hypovolemia - Endotracheal tube positioned in right mainstem bronchus
is a problem but the co2 reading would not change, so
ANSWER is A.
What is the target Vt for individual on mechanical ventilation - 6-8 ml/kg (of
ideal body weight) This is new strategy as of January 2015
Is the following Static OR Dynamic Compliance:
Means flow throughout the respiratory system has stopped and all
ventilatory muscle activity is absent. _______ conditions can be imposed
with an inspiratory pause when a patient is sedated and mechanically
ventilated. - Static Compliance
