A 76-Year-Old Man Is Admitted With Complaints Of Sudden, Sharp, "Tearing" Chest
Pain Radiating To The Shoulders, Neck, And Back. He Has Been In Apparent Good
Health Except For A History Of Hypertension. Vital Signs Are Blood Pressure,
180/96 Mm Hg; Heart Rate, 90 Beats/Min; And Respiratory Rate, 26 Breaths/Min. He
Is Dyspneic, And His Electrocardiogram Shows Nonspecific ST-T Wave Changes.
Which Of The Following Would Not Be An Important Aspect Of Care For This
Patient?
A. Control His Blood Pressure.
B. Provide Adequate Analgesia.
C. INITIATE FIBRINOLYTIC THERAPY.
D. Prepare The Patient For Surgery.
Fibrinolytic Therapy Is Contraindicated If Dissecting Thoracic Aortic Aneurysm Is
Suspected. All Of The Other Interventions Are Appropriate.
Which Of The Following Interventions Would Be Helpful In Prevention Of Aspiration
In A Patient Receiving Enteral Feedings?
A. Check For Gastric Residuals Every 4 Hours.
B. USE A SMALL-BORE DUODENAL FEEDING TUBE.
C. Use A High-Fat Feeding.
D. Add Blue Food Coloring To The Enteral Feeding.

A. Myocarditis
B. HEART FAILURE
C. Myocardial Infarction
D. Post cardiotomy
Any Injury To The Myocardium Would Cause Elevation Of Cardiac Isoenzymes.
Myocarditis, Myocardial Infarction, And Cardiotomy Cause Injury To The
Myocardium.
The Ability Of The Brain Contents To Be Shifted To Prevent Intracranial
Hypertension When Intracranial Volume Increases Is Referred To As:
A. COMPENSATION.
B. Autoregulation.
C. Normalization.
D. Feedback.
Remember The Difference Between Compensation And Autoregulation.
Compensation Relates To Intracranial Volumes And Resultant Pressure.
Autoregulation Relates To The Ability Of The Cerebral Vessels To Change Size To
Normalize Blood Flow
Which Of The Following Is Not A Therapeutic Effect Of Nifedipine When Used For
Angina?
A. Decreased Preload.
B. Decreased Afterload.
C. DECREASED CONTRACTILITY.
D. Relieve Vasospasm.
Nifedipine Decreases Myocardial Oxygen Consumption By Dilating Veins And
Arteries, Thereby Decreasing Preload And Afterload. Nifedipine Also Decreases
Vasospasm And Potential For Vasospasm. Unlike Diltiazem And Verapamil,
Nifedipine Does Not Significantly Decrease Contractility.
Emergency Decompression Of A Tension Pneumothorax Includes Needle Puncture
At Which Of The Following Locations?
, CCRN- CRITICAL CARE REGISTERED NURSE | 2024/2025 TEST BANK
A. Fifth Intercostal Space At The Midclavicular Line On The Affected Side

A 52-Year-Old Man Is Admitted With Hepatic Failure Caused By Chronic Alcoholism.
He Is Nonresponsive To Verbal Stimuli At This Time. Which Dietary Restrictions
Would Be Maintained For A Patient With Hepatic Encephalopathy?
A. PROTEIN AND SODIUM
B. Fat And Potassium
C. Potassium And Carbohydrates
D. Sodium And Potassium
Protein Is Restricted Because Its Breakdown Causes Increased Ammonia Levels.
Sodium Is Restricted Because Patients With Hepatic Disease Have Increased
Circulating Levels Of Aldosterone, Which Causes Increased Sodium Reabsorption In
The Distal Tubule And Resultant Edema.
A 24-Year-Old Man Is Admitted To The Critical Care Unit After Sustaining A
Pulmonary Contusion In A Motor Vehicle Collision. He Has No History Of Cardiac Or
Pulmonary Disease. Over The Last Few Hours, He Has Been Complaining Of
Increasing Dyspnea, His Respiratory Rate Has Been Increasing, And His Oxygen
Saturation Via Pulse Oximetry Has Been Decreasing. Breath Sound Assessment
Reveals Fine Crackles Bilaterally. Arterial Blood Gases Reveal Respiratory Alkalosis
And Hypoxemia. Chest X-Ray Film Reveals Patchy Infiltrates. Acute Respiratory
Distress Syndrome (ARDS) Is Diagnosed. Oxygen Therapy Is Initiated, And Arterial
Blood Gases Are Monitored Closely. The Massive Atelectasis That Occurs In Acute
Respiratory Distress Syndrome Is A Classic Example Of Intrapulmonary Shunt.
Intrapulmonary Shunting Is Best Described As Which Of The Following?
A. Ventilated Alveoli Having Blocked Perfusion.
B. PERFUSED ALVEOLI HAVING BLOC

A Patient Admitted With Goodpasture Syndrome Has Developed Acute Tubular
Necrosis. The Patient's Phosphorus Level Is 6.5 Mg/Dl. Control Of The Phosphorus
Is Important To Avoid Complications From Which Of The Following?
A. Hyponatremia
B. HYPOCALCEMIA
C. Hypernatremia
D. Hypercalcemia
Associate Phosphorus And Calcium With A Seesaw. When One Side Of The Seesaw Is
Up, The Other Is Down. This Process Is Consistent With Normal And Abnormal
Kidney Function. Choose "Hypocalcemia." You Do Not Really Need To Know What
Goodpasture Syndrome Is To Answer The Question Correctly.
A 65-Year-Old Man Is Admitted To The Critical Care Unit With A Diagnosis Of Septic
Shock. He Has Been Receiving Chemotherapy For Lung Cancer. His Skin Is Warm

Blood Pressure 80/50 Mm Hg, Heart Rate 120 Beats/Min And Regular, Respiratory
Rate 32 Breaths/Min And Regular, And Temperature 39° C. Arterial Blood Gases
Reveal The Following: Ph7.25pao260 Mm Hgpaco225 Mm Hghco313 Meq/Loxygen
Saturation86% What Hemodynamic Alteration Should The Nurse Anticipate?
A. Decreased Cardiac Output (CO)
B. INCREASED VENOUS OXYGEN SATURATION (SVO2)
C. Increased Systemic Vascular Resistance (SVR)
D. Increased Oxygen Consumption
Early Septic Shock Is Different From Most Forms Of Shock Because The Main
Problem Is Oxygen Extraction Rather Than Oxygen Delivery. So Think Opposite Of
Hypovolemic Shock. CO Is Increased Instead Of Decreased. SVR Is Decreased
Instead Of Increased. And The Svo2 Is Increased Instead Of Decreased.
