A 34-Week Gestational Age Infant Is Receiving Mechanical Ventilation And The
Chest Is Being Transilluminated. The Transillumination Device Produces A Small
Halo Appearance At The Point Of Contact With The Skin. Which Of The Following
Does This Indicate?
A. Pneumothorax
B. Pneumomediastinum
C. Pneumopericardium
D. Normal Lung Appearance
ANS:
Explanations:
(U) A. When There Is Excessive Air Or Fluid Present, Light Transmission Will Be
Increased. Transillumination Of The Air-Filled Chest In The Neonate With A
Pneumothorax Results In Lighting Up The Affected Side Of The Chest.
(U) B. Transillumination Will Light Up The Chest In Patients With
Pneumomediastinum. See Explanation A.
(U) C. Transillumination Is Not Used To Determine Pneumopericardium.
(C) D. The Halo Appearance Is Produced By A Normal, Inflated Lung Absorbing The
Light.
According To The Change Of Shift Report, A Patient In The Icu Is Receiving An
Fio2 Of 0.40 And Peep Of 5 Cm H2o. Arterial Blood Gases Are Stable And Weaning
Is Being Considered. While Assessing The Patient, A Respiratory Therapist Notes
The Fio2 Is 0.60 And Peep Is 10 Cm H2o. Which Of The Following Actions Should
The Therapist Take First?
A. Return The Patient To The Reported Settings And Document The Findings.
B. Report The Findings To The Physician And Complete An Incident Report.
,C. Report The Findings To The Supervisor And Complete An Incident Report.
D. Assess The Patient And Determine If The Settings Are Appropriate.
ANS:
Explanations:
(U) A. The Therapist Must First Determine If The Current Settings Are Appropriate
For The Patient And If There Have Been Orders To Change The Parameters.
(U) B. The Therapist Must First Determine That An Incident Occurred And The
Parameters Were Changed Incorrectly.
(U) C. See Explanation B.
(C) D. The Therapist Should Have Previously Reviewed The Orders For Changes,
But, If Not Done, The First Obligation Is To Determine If The Parameters Are
Correct Based On Patient Assessment.
The Spirometry Of A Patient Shows A 20% Increase In Forced Expiratory Volume In
1 Second (Fev1) After Receiving Short-Acting Beta2 Bronchodilator Therapy. This
Indicates
A. Reversible Obstructive Airways Disease.
B. Restrictive Lung Disease.
C. Insignificant Response To Bronchodilator.
D. Fixed Upper Airway Obstruction.
ANS:
Explanations:
(C) A. The Increase Indicates That The Obstruction Of The Airways Responds To
Short-Acting Beta-Adrenergic Agents.
(H) B. Restrictive Disease Would Not Be Affected By The Administration Of A Beta-
Adrenergic.
(U) C. An Increase Of 12% Or Greater In The Fev1 Indicates A Significant Response
To The Beta-Adrenergic Drug.
,(H) D. A Fixed Upper Airway Obstruction Would Not Be Affected By The
Administration Of A Beta-Adrenergic.
A 27-Year-Old Patient Has A Carboxyhemoglobin (Cohb) Level Of 10.3% On
Admission To The Burn Unit. Oxygen By Nonrebreathing Mask Should Be
A. Utilized Until The Patient's Cohb Level Returns To The Normal Range.
B. Utilized Until The Patient's Oxygen Saturation (Spo2) Is >91%.
C. Weaned To Obtain An Oxygen Saturation (Spo2) >94%.
D. Discontinued If The Patient Has Concomitant Copd.
ANS:
Explanations:
(C) A. Co Has 200 Times More Affinity To Hemoglobin Than Oxygen. 100%
Oxygen Must Be Provided Until The Co Has Been Displaced.
(H) B. The Spo2 Does Not Differentiate Between Carboxyhemoglobin And
Oxyhemoglobin.
(H) C. The Spo2 Does Not Differentiate Between Carboxyhemoglobin And
Oxyhemoglobin.
(H) D. Co Must Be Displaced From Hemoglobin To Allow Satisfactory Oxygen
Delivery To Tissues, Regardless Of Previous Diagnoses.
A Respiratory Therapist Collects The Following Data On A 58-Year-Old Male Who
Has Been Receiving Vc, A/C Ventilation For The Past 24 Hours Following Thoracic
Surgery: The Patient Is Alert And Oriented. He Has An Spo2 Of 98% While
Receiving Ventilation With The Following Settings: The Best Weaning Method For
This Patient Is
A. A Spontaneous Breathing Trial.
B. Simv Mode, Mandatory Rate 14, And Tidal Volume 600 Ml.
C. Ps Ventilation At 20 Cm H2o.
, D. Pc Ventilation At 25 Cm H2o And Mandatory Rate Of 12.
ANS:
Explanations:
(C) A. This Patient Will Probably Not Need An Extended Weaning Period; This Is
The Best Method For Rapid Weaning.
(U) B. This Would Unnecessarily Prolong The Course Of Mechanical Ventilation.
(U) C. High Levels Of Pressure Support Will Unnecessarily Prolong Weaning.
(U) D. These Settings Are Not A Weaning Method.
During An Aerosol Treatment With Albuterol, A Patient Complains Of Dizziness
And Light-headedness. The Patient's Pulse Increases From 70 To 85/Min During The
Treatment. Which Of The Following Notes Should Be Recorded In The Patient's
Chart?
1. The Patient Had Tachycardia As A Result Of The Medication.
2. The Patient Was Instructed To Breathe More Slowly During Therapy.
3. The Patient Complained Of Dizziness And Lightheadedness.
4. The Nurse Was Notified Of The Patient's Response To Therapy.
A. 1, 2, And 3 Only
B. 1, 2, And 4 Only
C. 1, 3, And 4 Only
D. 2, 3, And 4 Only
ANS:
Explanations:
1. False. A Pulse Of 85/Min Does Not Indicate Tachycardia. Recording The Heart
Rate Is Appropriate, But Determining The Cause Of The Heart Rate Change Is Out
Of The Therapist's Scope Of Practice.
2. True. The Patient Should Be Instructed To Breathe More Slowly Since A Reaction
Of Dizziness And Lightheadedness Is Associated With Hyperventilation.
3. True. The Therapist Should Document Adverse Reactions Associated With
Therapy.
