PATIENT ASSESSMENT:
1. A 64-year-old patient is being resuscitated for full cardiopulmonary arrest. After several
unsuccessful attempts, the patient is orally intubated with a size 7.0 mm endotracheal tube. The
physician is unable to establish a peripheral or central intravenous line. The ECG monitor now
shows the following rhythm (sinus rhythm with regular positive p-wave, bradycardia). The
respiratory therapist should recommend administration of:
A. lidocaine by small volume nebulizer.
B. atropine through the endotracheal tube.
C. epinephrine by intra-cardiac injection.
D. amiodarone by intraosseous injection. - Correct Answer: Graph shows sinus rhythm with
regular positive p-wave, bradycardia (slow heart rate, heart beat more than 5 boxes wide is
bradycardia; boxes less than 3 wide is tachycardia). Since no IV can be inserted, we will
administer drugs through endotracheal tube.... but what drug...lidocaine would be for gag reflex
or coughing, epinephrine very powerful used for emergencies, for flat line, amiodarone might
be used for ventricular disrythmias, pvc's; atropine is for Bradycardia so ANSWER is Atropine.
2. A patient involved in a motor vehicle accident has sustained a long bone fracture and
remains in traction. The patient suddenly complains of chest pain, and becomes tachypneic and
tachycardiac. To determine the cause of the problem the respiratory therapist should
recommend
A. administering 100% oxygen.
B. a V/Q scan.
,C. streptokinase.
D. a STAT chest x-ray. - Correct Answer: long bone fracture combined with patient just lying
around makes them very susceptible for pulmonary emboli; so which of these 4 would best find
pulmonary emboli. A V/Q scan will show areas of ventilation and profusion and pulmonary
emboli could cause area of deadspace, so ANSWER is B (streptokinase is an effective clot buster,
STAT chest x-ray would be helpful but not be the best for diagnosing emboli).
3. The respiratory therapist is called to the emergency department to evaluate a patient who
was brought in via an ambulance due to a motor vehicle accident. The patient is cold and
clammy with a blood pressure of 82/46 mm Hg. The ECG monitor shows sinus tachycardia with
occasional PVC. Which of the following should the therapist evaluate at this time?
A. Serum electrolytes
B. Cardiac enzymes
C. Hb and Hct levels
D. 12 lead ECG - Correct Answer: Patient seems to be experiencing shock, serum electrolytes
would be a good choice, cardiac enzymes would be good but very expensive, 12 lead ECG is
another good test but more appropriate if we were mainly concerned with the heart; Hb and
Hct most closely corresponds to shock because you know the patient was in an accident and
probably had a lot of blood loss, so ANSWER is C Hb and Hct
4. Viral infections cause WBC to (INCREASE OR DECREASE)
Bacterial infections cause WBC to (INCREASE OR DECREASE) - Correct Answer: Viral WBC
Decrease
Bacterial WBC Increase
5. Which of the following drugs should the respiratory therapist recommend to lower a
patient's blood pressure as well as decrease his ventricular afterload?
A. Norepinephrine
B. Propranolol
C. Procainamide
,D. Sodium nitroprusside - Correct Answer: Norepinephrine will increase blood pressure and
afterload; Propranolol will slow the heart down but doesn't do anything for the afterload;
Procainamide is an antirhythmic agent; Sodium Nitroprusside is a vasodilator, which will reduce
blood pressure and decrease the afterload.
6. A pleural friction rub is associated with all of the following conditions EXCEPT
A. pneumonia.
B. tuberculosis.
C. pleurisy.
D. pulmonary edema. - Correct Answer: Pulmonary edema has a lot of excess fluid in the
lung so there would be no friction rub, so ANSWER is D pulmonary edema
7. A 40-year-old patient who smokes 2 packs of cigarettes per day has a carboxyhemoglobin
level of 6.4%. These results are most consistent with
A. Severe COPD
B. History of dyspnea on exertion
C. Need for supplemental oxygen
D. Expected level for this patient - Correct Answer: Nothing about COPD will give you a
carboxyhemoglobin level of 6.4%; 6.4% is a typical level for a heavy smoker so ANSWER is D,
Expected level for this patient.
8. The following data has been obtained from a 28-week gestational age infant who was born
premature:
Color: Cyanotic
Chest x-ray: Cardiac enlargement
Chest Sounds: Systolic murmur
Respiratory rate: 55 Br/min.
SpO2: 80%
, Which of the following diagnostic tests should the respiratory therapist recommend?
A. Pre- and post-ductal blood gas studies
B. L/S ratio
C. New Ballard Score
D. Capillary blood gas - Correct Answer: L/S ratio is done prior to birth to measure ability to
produce surfactant; Ballard Score measures gestational age, Capillary blood gas is not going to
determine the heart problems we are seeing, so ANSWER is A, Pre and Post-ductal blood gas
studies;
9. AIRWAY CARE:
A nasopharyngeal airway is indicated for which of the following patients?
A. unconscious patient with a closed head injury
B. conscious patient with an ineffective cough
C. alert patient who is expectorating a large amount of secretions
D. uncooperative patient - Correct Answer: Nasopharyngeal airway is not for unconscious or
uncooperative patients. Patients conscious and expectorating large amounts of secretions on
their own does not indicate need for nasopharyngeal airway. So, ANSWER is B, conscious
patient with an ineffective cough is the answer and best use of this airway.
10. A 43-week gestational age infant has just been delivered and is stained with meconium. The
physician has asked that the baby be intubated and suctioned immediately. The respiratory
therapist should recommend intubating the baby with which of the following size endotracheal
tubes?
A. 2.0 mm
B. 2.5 mm
C. 3.0 mm
D. 4.0 mm - Correct Answer: This baby is post-term (by 3 weeks) so the baby probably
weighs about 3,000 grams at full term so you can go a full-size airway at 3.0mm ANSWER is C,
3.0 mm. You wouldn't use a 4.0mm until the baby is about 1 year old.
