PATIENT ASSESSMENT:
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
ANSWER is B
RATIONALE: Since the patient received Lasix and nasogastric tube, they are
losing fluids, and a side effect of fluid loss is a decrease in electrolytes, (there
isn't enough evidence of heart attack to justify cardiac enzymes, also they are
used to confirm a heart attack).
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
,ANSWER is A.
RATIONALE: 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
ANSWER: 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.
ANSWER: Static Compliance
Is the following Static OR Dynamic Compliance:
Flow at airway opening is zero. Mechanics are evaluated under ______
conditions, when non-intubated patient breathes spontaneously.
ANSWER: Dynamic Compliance
A balloon tipped flow directed catheter is positioned in the pulmonary artery
with the balloon deflated. Which of the following pressures will be measured by
the proximal lumen:
a. Cvp
b. Pap
c. Pwp
d. Map
ANSWER is A.
RATIONALE: Cvp = deflated/proximal lumen
Pap = deflated/distal
Pwp = inflated/wedged
All of the following will affect the accuracy of a capnography EXCEPT
a. Long sampling line
b. Low sampling flow
c. Condensation in the tubing
d. Use of desiccant
ANSWER is D
,RATIONALE: Gas will pass through and out of a long sampling line before
reaching analyzer so, low sampling flow will not give you enough information for
a good reading, and condensation as a rule is always a problem especially in
analyzers. Dessicant removes moisture from the gas, which is a good thing, so
A 1000 g neonate (normal baby is 3000 g) is stable in nicu. Which of the following
should the respiratory therapist use to monitor the neonates overall
cardiopulmonary status.
a. TcPCO2 and TcPO2 monitor
b. Arterial blood gas analysis Q4
c. SpO2 monitor
d. Capillary gas analysis Q8
Answer is A
RATIONALE: Since the baby is stable, go less invasive, also go continuous
monitoring (not 4 hour or 8 hour), Transcutaneous (Tc) continuous monitoring of
CO2 and O2 is the best.
A unilateral wheeze would most likely indicate which of the following.
a. Asthma
b. Atelectasis
c. Foreign body aspiration
d. Epiglottitis
ANSWER is C
RATIONALE: You wouldn't have asthma on just one side (unilateral), atelectasis
would cause diminished breath sounds, with epiglottitis you would get stridor,
since you are only hearing wheezing on one side, you are hearing it on the side
where you aspirated something,
All of the following would be associated with the presence of a pneumothorax
EXCEPT
a. Tracheal deviation
b. Dull percussion
c. Absent breath sounds
d. Respiratory distress
RATIONALE: With pneumothorax you would hear a high pitch hyperresonnance,
breath sounds would be absent, and respiratory distress could be present. Dull
percussion would NOT be present,
, so ANSWER is B.
What should you recommend FIRST for a patient with multifocal pvc's
a. Administration of lidocaine
b. Administration of 100% oxygen
c. Administration of atropine
d. Administration of epinephrine
ANSWER is B
RATIONALE: Multiple pvc's coming from multiple locations (multifocal) is a real
problem and you should administer oxygen FIRST,. lidocaine will help reduce
irritability of heart and help with pvc's but would not be first option, atropine is
used for bradycardia and cardiac irregularities but not pvc's, epinephrine is
emergency drug not for pvc's but more for pulseless ventricular tachycardia or
ventricular fibrilation where heart is not responding .
What is the normal range for the mean pulmonary artery pressure in an adult
a. 2-6 mm Hg
b. 4-12 mmHg
c. 9-18 mmHg
d. 21-28 mmHg
RATIONALE: Mean pulmonary artery pressure in an adult should be in the teens
so best ANSWER is C
A patient in the emergency dept has frothy secretions, moist crackles, and
tachypnea. The patient has marked dyspnea and a history of heart disease.
Which of the following should the respiratory therapist recommend.
1.suction immediately
2.administer 100% oxygen
3.place in Fowlers position
4.administer furosemide
ANSWER is 2,3,4
RATIONALE: This is an emergency, they are having heart problems, dyspnea,
frothy secretions indicating severe pulmonary edema, etc. so 100% oxygen
immediately, having the patient in the Fowlers position (an upright position) will
help pull fluid down away from the lungs, furosemide is a lasix (loop diuretic)
which gets rid of excess fluid. You do NOT suction someone with frothy
secretions and heart problems, this just delays appropriate therapy.
