VERSION 3 (V3) 160 QUESTIONS| ACTUAL EXAM
Question 1 Of 160
A 48-Year-Old Female Is Admitted To The ED With Diaphoresis, Jugular Venous
Distension, And 3+ Pitting Edema In The Ankles. These Findings Are Consistent With:
A. Liver Failure.
B. Pulmonary Embolism.
C. Heart Failure.
D. Electrolyte Imbalances.
ANS: C.
Rationale: The Symptoms Of Diaphoresis, Jugular Venous Distension, And Pitting Edema
Indicate Fluid Overload And Compromised Cardiac Function, Which Are Hallmark Signs Of
Heart Failure. Liver Failure Can Also Cause Fluid Retention, But It Typically Presents With
Other Signs Like Jaundice And Ascites. Pulmonary Embolism Would Usually Present With
Sudden Dyspnea And Hypoxemia Rather Than These Signs.
Question 2 Of 160
A Patient Is Admitted To The ED Following A Motor Vehicle Accident. On Physical Exam,
The Respiratory Therapist Discovers That Breath Sounds Are Absent In The Left Chest With
A Hyperresonant Percussion Note. The Trachea Is Shifted To The Right. The Patient's Heart
Rate Is 45/Min, Respiratory Rate Is 30/Min, And Blood Pressure Is 60/40 Mm Hg. What
Action Should The Therapist Recommend First?
A. Call For A STAT Chest X-Ray.
B. Insert A Chest Tube Into The Left Chest.
C. Needle Aspirate The 2nd Left Intercostal Space.
D. Activate The Medical Emergency Team To Intubate The Patient.
,ANS: C.
Rationale: The Clinical Signs Indicate A Tension Pneumothorax, Where Air Trapped In The
Pleural Space Increases Pressure And Collapses The Lung. Immediate Decompression Is
Crucial, And Needle Thoracostomy Is The Fastest Way To Relieve The Pressure Before
Further Intervention Like Chest Tube Insertion.
Question 3 Of 160
All Of The Following Strategies Are Likely To Decrease The Likelihood Of Damage To The
Tracheal Mucosa EXCEPT:
A. Maintaining Cuff Pressures Between 20 And 25 Mm Hg.
B. Using The Minimal Leak Technique For Inflation.
C. Using A Low-Residual-Volume, Low-Compliance Cuff.
D. Monitoring Intracuff Pressures.
ANS: D.
Rationale: While Monitoring Intracuff Pressures Is Important, It Does Not Actively Prevent
Damage To Tracheal Mucosa. Maintaining Appropriate Cuff Pressures And Using The
Minimal Leak Technique Are Directly Aimed At Minimizing Pressure On The Trachea.
Question 4 Of 160
A 52-Year-Old Post-Operative Cholecystectomy Patient's Breath Sounds Become More
Coarse Upon Completion Of Postural Drainage With Percussion. The Respiratory Therapist
Should Recommend:
A. Continuing The Therapy Until Breath Sounds Improve.
B. Administering Dornase Alpha.
C. Administering Albuterol Therapy.
D. Deep Breathing And Coughing To Clear Secretions.
ANS: D.
Rationale: Coarse Breath Sounds Suggest Retained Secretions. Deep Breathing And
Coughing Are Effective Techniques To Mobilize And Clear Secretions, Improving Airway
Patency.
,Question 5 Of 160
A 65 Kg Spinal Cord Injured Patient Has Developed Atelectasis. His Inspiratory Capacity Is
30% Of His Predicted Value. What Bronchial Hygiene Therapy Would Be Most Appropriate
Initially?
A. IS / SMI
B. IPPB With Normal Saline
C. Postural Drainage And Percussion
D. PEP Therapy
ANS: B.
Rationale: In Cases Of Significant Atelectasis, Especially With Reduced Inspiratory
Capacity, IPPB Can Help Deliver Positive Pressure And Improve Lung Expansion. Normal
Saline May Help Mobilize Secretions.
Question 6 Of 160
A Patient On VC Ventilation Has Demonstrated Auto-PEEP On Ventilator Graphics. Which
Of The Following Controls, When Adjusted Independently, Would Increase Expiratory
Time?
1. Tidal Volume
2. Respiratory Rate
3. Inspiratory Flow
4. Sensitivity
ANS: 1, 2, And 3 Only.
Rationale: Increasing Tidal Volume Or Decreasing Respiratory Rate Can Lead To Increased
Expiratory Time. Increasing Inspiratory Flow Could Also Affect How Long It Takes To
Exhale Completely. Sensitivity Adjustments Generally Do Not Impact Expiratory Time
Directly.
, Question 7 Of 160
Which Of The Following Would Be The Most Appropriate Therapy For A Dyspneic Patient
Who Has Crepitus With Tracheal Deviation To The Left And Absent Breath Sounds On The
Right?
A. Perform Chest Physiotherapy
B. Administer An IPPB Treatment
C. Insert An Endotracheal Tube
D. Insert A Chest Tube
ANS: D.
Rationale: Crepitus And Tracheal Deviation Suggest A Possible Tension Pneumothorax Or
Significant Pleural Effusion On The Right Side, Which Would Necessitate Immediate Chest
Tube Insertion To Relieve Pressure And Restore Lung Function.
Question 8 Of 160
A 55-Year-Old Post Cardiac Surgery Patient Has The Following ABG Results: Ph 7.50,
Paco2 30 Torr, Pao2 62 Torr, HCO3 25 Meq/L, Sao2 92%, HB 14 G/Dl, BE +2. Venous
Blood Gas Results Are Ph 7.39, Pvco2 43 Torr, Pvo2 37 Torr, And Svo2 66%. Calculate The
Patient's C(A-V)O2.
A. 2.5 Vol%
B. 4.0 Vol%
C. 5.0 Vol%
D. 5.5 Vol%
ANS: C.
Rationale: The C(A-V)O2 Can Be Calculated From The Arterial And Venous Oxygen
Content. The Difference Represents The Amount Of Oxygen Extracted By The Tissues, And
In This Case, The Calculated Value Indicates Normal Extraction.
