Exam 18: Pulmonary Diagnostic Procedures

The patient's arterial blood gas (ABG)values on room air are PaO₂,40 mm Hg; pH,7.10; PaCO₂,44 mm Hg; andHCO₃¯,16 mEq/L.What is the interpretation of the patient's ABG?

In a patient who is hemodynamically stable,which procedure can be used to estimate the PaCO₂ levels?

On admission,a patient presents with a respiratory rate of 24 breaths/min,pursed-lip breathing,heart rate of 96 beats/min in sinus tachycardia,and a blood pressure of 110/68 mm Hg.The patient's arterial blood gas (ABG)values on room air are PaO₂,70 mm Hg; pH,7.38; PaCO₂,52 mm Hg; andHCO₃¯ ,34 mEq/L.What diagnoses would be most consistent with the above arterial blood gas values?

On admission,a patient presents with a respiratory rate of 28 breaths/min,heart rate of 108 beats/min in sinus tachycardia,and a blood pressure of 140/72 mm Hg.The patient's arterial blood gas (ABG)values on room air are PaO₂,60 mm Hg; pH,7.32; PaCO₂,45 mm Hg; andHCO₃¯ ,26 mEq/L.What action should the nurse anticipate for this patient?

What chest radiography finding is consistent with a left pneumothorax?

A patient presents moderately short of breath and dyspneic.A chest radiographic examination reveals a large right pleural effusion with significant atelectasis.The practitioner would be most likely to prescribe which procedure?

A patient's pulse oximeter alarm goes off.The monitor reads 82%.What is the first action the nurse should perform?

Severe coughing and shortness of breath during a thoracentesis are indicative of what complication?

Which ABG values reflect compensation?

A patient has the following arterial blood gas (ABG)values: pH,7.20; PaO₂,106 mm Hg; pCO₂,35 mm Hg; andHCO₃¯,11 mEq/L.What symptom would be most consistent with the ABG values?

A static lung compliance of 40 mL/cm H₂O is indicative of which disorder?

What medication may be included in the preprocedural medications for a diagnostic bronchoscopy?

A patient is admitted with acute lung failure secondary to pneumonia.Arterial blood gas (ABG)values on the current ventilator settings are pH,7.37; PaCO₂,50 mm Hg; and HCO₃¯,27 mEq/L.What is the correct interpretation of the patient's ABG values?

Which patient would be considered hypoxemic?

A patient presents with absent lung sounds in the left lower lung fields,moderate shortness of breath,and dyspnea.The nurse suspects pneumothorax and notifies the practitioner.Orders for a STAT chest radiography and reading are obtained.Which finding best supports the nurse's suspicions?

The patient's arterial blood gas (ABG)values on room air are PaO₂,70 mm Hg; pH,7.31; PaCO₂,52 mm Hg; and ,24 mEq/L.What is the interpretation of the patient's ABG?

A bronchoscopy is indicated for a patient with what condition?

What does an intrapulmonary shunting value of 35% indicate?

A patient is intubated,and sputum for culture and sensitivity is ordered.Which of the following is important for obtaining the best specimen?

Place the steps for analyzing arterial blood gases in the proper order. 1)Assess HCO₃¯ level for metabolic abnormalities 2)Assess PaO₂ for hypoxemia 3)Examine PaCO₂ for acidosis or alkalosis 4)Re-examine pH to determine level of compensation 5)Examine pH for acidemia or alkalemia
