Certainly! Here's the revised version without the section on where to buy the documents: Overview of Pilbeam’s Mechanical Ventilation, 6th Edition Test Bank Pilbeam’s Mechanical Ventilation: Physiological and Clinical Applications is a key text in the field of respiratory therapy and nursing, specifically related to mechanical ventilation techniques, modes, and the care of ventilated patients. The 6th edition, updated by J.M. Cairo, would cover the latest advancements in ventilator technology, patient management, and clinical applications in intensive care. Key Features of the Test Bank: 1. Comprehensive Coverage of Mechanical Ventilation Concepts: Basic principles of mechanical ventilation: Understanding how ventilators work and the physiology of respiration. Indications for mechanical ventilation: Including respiratory failure, pulmonary disease, and other critical care situations. Ventilator settings and modes: Detailed questions about modes of ventilation such as pressure-controlled, volume-controlled, assist-control, and others. Ventilator graphics: Interpreting waveforms and understanding the parameters that need to be adjusted on ventilators. Complications of mechanical ventilation: Addressing complications like barotrauma, ventilator-associated pneumonia (VAP), and oxygen toxicity. Weaning and extubation protocols: Understanding the process of safely removing a patient from mechanical ventilation. 2. Multiple-Choice Questions (MCQs): The test bank is typically designed to help you prepare for exams by providing practice multiple-choice questions. The questions are designed to test both your theoretical knowledge and clinical understanding of mechanical ventilation concepts. 3. Clinical Application and Case Scenarios: Many test banks include case study questions that test your ability to apply mechanical ventilation principles to real-life clinical scenarios. This helps prepare you for exams and situations where you need to make decisions about patient care. 4. Answer Key with Rationales: Each question would come with a correct answer and a rationale explaining why that answer is correct, as well as why the other options are not. This enhances learning by helping you understand the clinical reasoning behind ventilator management and patient care decisions. 5. Updated Content Reflecting the Latest Clinical Guidelines: The test bank would include updates from the 6th edition of Pilbeam’s book, which incorporates the latest advancements in mechanical ventilation techniques, new ventilator modes, and emerging clinical protocols for managing ventilated patients. Sample Questions from the Test Bank: Here are a few example questions you might find in the test bank: 1. A patient is placed on a mechanical ventilator using the assist-control (A/C) mode. The ventilator settings are as follows: tidal volume 500 mL, rate 12 breaths per minute, FiO2 0.50, PEEP 5 cm H2O. The patient begins to trigger the ventilator more frequently. Which of the following is the most appropriate action? A) Decrease the tidal volume to reduce patient-triggered breaths. B) Increase the ventilator rate to match the patient’s respiratory drive. C) Switch the mode to pressure support to allow for more spontaneous breathing. D) Increase the PEEP to improve oxygenation. Answer: C) Switch the mode to pressure support to allow for more spontaneous breathing. Rationale: The patient’s increased triggering of the ventilator suggests they are attempting to breathe spontaneously, and switching to pressure support mode will assist with this while maintaining spontaneous breathing. 2. In a patient with acute respiratory distress syndrome (ARDS) on mechanical ventilation, the nurse notices that the patient's arterial blood gases (ABGs) show a PaO2 of 65 mmHg, and the ventilator is set to deliver 60% FiO2. What should the nurse do next? A) Increase the FiO2 to 100%. B) Add positive end-expiratory pressure (PEEP) to improve oxygenation. C) Administer diuretics to reduce fluid overload. D) Decrease the tidal volume to reduce barotrauma risk. Answer: B) Add positive end-expiratory pressure (PEEP) to improve oxygenation. Rationale: In ARDS, adding PEEP can improve oxygenation by preventing alveolar collapse and improving oxygenation, especially when the FiO2 is already high. 3. A patient is receiving mechanical ventilation and is being weaned. The nurse assesses the patient’s readiness for extubation. Which of the following findings suggests that the patient is not yet ready for extubation? A) The patient is able to follow simple commands. B) The patient’s vital signs are stable without significant fluctuations. C) The patient demonstrates rapid shallow breathing with a respiratory rate of 36 breaths per minute. D) The patient has an adequate cough and can clear secretions. Answer: C) The patient demonstrates rapid shallow breathing with a respiratory rate of 36 breaths per minute. Rationale: Rapid shallow breathing is indicative of respiratory distress and suggests that the patient is not yet ready for extubation. The patient should show adequate spontaneous breathing with stable respiratory patterns before extubation. How to Use the Test Bank Effectively: Self-Assessment: Use the test bank as a tool for self-assessment to identify areas of strength and weakness in your understanding of mechanical ventilation. Practice with Clinical Scenarios: Apply what you’ve learned by practicing with case studies or clinical scenarios. This will help you think critically about ventilator management and patient care in real-world situations. Review Rationales: Don’t just memorize the correct answers—take the time to read and understand the rationales. This is where you’ll gain valuable insights into the decision-making process and learn the reasoning behind each intervention. Prepare for Exams: Use the test bank to prepare for your exams, particularly in respiratory therapy, critical care nursing, and other programs where mechanical ventilation is a key topic. Group Study: Consider using the test bank for group study sessions to discuss questions and rationales with classmates. This can enhance your understanding and help reinforce key concepts. Why Should You Consider Using the Test Bank? Comprehensive Review: The test bank offers a complete review of the key principles and clinical applications of mechanical ventilation. Realistic and Relevant Questions: The questions mimic those that are likely to appear on exams in respiratory therapy or critical care nursing programs, making it an excellent preparation tool. Current Updates: The 6th edition update reflects the latest clinical practices and guidelines, so you are studying the most current information available. Increases Critical Thinking: The focus on clinical application and problem-solving ensures you are not only memorizing facts but also developing the critical thinking skills required for safe and effective ventilator management in patients. This test bank is a valuable tool for students and professionals seeking to deepen their understanding of mechanical ventilation in critical care and respiratory therapy. It will help reinforce important concepts, enhance exam preparation, and build the critical thinking necessary for effective patient management.

Chapter 01: Basic Terms and Concepts of Mechanical Ventilation
Cairo: Pilbeam’s Mechanical Ventilation: Physiological and Clinical Applications, 6th
Edition


MULTIPLE CHOICE

1. The body’s mechanism for conducting air in and out of the lungs is known as which of the
following?
a. External respiration
b. Internal respiration
c. Spontaneous ventilation
d. Mechanical ventilation
ANS: C
The conduction of air in and out of the body is known as ventilation. Since the question asks
for the body’s mechanism, this would be spontaneous ventilation. External respiration
involves the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the
pulmonary capillaries. Internal respiration occurs at the cellular level and involves movement
of oxygen from the systemic blood into the cells.

REF: pg. 2

2. Which of the following are involved in external respiration?
a. Red blood cells and body cells
b. Scalenes and trapezius muscles
c. Alveoli and pulmonary capillaries
d. External oblique and transverse abdominal muscles
ANS: C
External respiration involves the exchange of oxygen and carbon dioxide (CO2) between the
alveoli and the pulmonary capillaries. Internal respiration occurs at the cellular level and
involves movement of oxygen from the systemic blood into the cells. Scalene and trapezius
muscles are accessory muscles of inspiration. External oblique and transverse abdominal
muscles are accessory muscles of expiration.

REF: pg. 2

3. The graph that shows intrapleural pressure changes during normal spontaneous breathing is
depicted by which of the following?
a.

b.




c.




d.




ANS: B
During spontaneous breathing, the intrapleural pressure drops from about 5 cm H2O at end-
expiration to about 10 cm H2O at end-inspiration. The graph depicted for answer B shows
that change from 5 cm H2O to 10 cm H2O.

REF: pg. 3

4. During spontaneous inspiration alveolar pressure (PA) is about: ________________.
a. 1 cm H2O
b. +1 cm H2O
c. 0 cm H2O
d. 5 cm H2O
ANS: A
1 cm H2O is the lowest alveolar pressure will become during normal spontaneous
ventilation. During the exhalation of a normal spontaneous breath the alveolar pressure will
become 1 cm H2O.

REF: pg. 4

5. The pressure required to maintain alveolar inflation is known as which of the following?
a. Transairway pressure (PTA)
b. Transthoracic pressure (PTT)
c. Transrespiratory pressure (PTR)
d. Transpulmonary pressure (PL)
ANS: D

,https://www.stuvia.com/




The definition of transpulmonary pressure (PL) is the pressure required to maintain alveolar
inflation. Transairway pressure (PTA) is the pressure gradient required to produce airflow in the
conducting tubes. Transrespiratory pressure (PTR) is the pressure to inflate the lungs and
airways during positive-pressure ventilation. Transthoracic pressure (PTT) represents the
pressure required to expand or contract the lungs and the chest wall at the same time.

REF: pg. 4

6. Calculate the pressure needed to overcome airway resistance during positive-pressure
ventilation when the proximal airway pressure (PAw) is 35 cm H2O and the alveolar pressure
(PA) is 5 cm H2O.
a. 7 cm H2O
b. 30 cm H2O
c. 40 cm H2O
d. 175 cm H2O
ANS: B
The transairway pressure (PTA) is used to calculate the pressure required to overcome airway
resistance during mechanical ventilation. This formula is PTA = Paw - PA.

REF: pg. 4

7. The term used to describe the tendency of a structure to return to its original form after being
stretched or acted on by an outside force is which of the following?
a. Elastance
b. Compliance
c. Viscous resistance
d. Distending pressure
ANS: A
The elastance of a structure is the tendency of that structure to return to its original shape after
being stretched. The more elastance a structure has, the more difficult it is to stretch. The
compliance of a structure is the ease with which the structure distends or stretches.
Compliance is the opposite of elastance. Viscous resistance is the opposition to movement
offered by adjacent structures such as the lungs and their adjacent organs. Distending pressure
is pressure required to maintain inflation, for example, alveolar distending pressure.

REF: pg. 5

8. Calculate the pressure required to achieve a tidal volume of 400 mL for an intubated patient
with a respiratory system compliance of 15 mL/cm H2O.
a. 6 cm H2O
b. 26.7 cm H2O
c. 37.5 cm H2O
d. 41.5 cm H2O
ANS: B
C = V/P then P = V/C

REF: pg. 5

9. Which of the following conditions causes pulmonary compliance to increase?
a. Asthma
b. Kyphoscoliosis
c. Emphysema
d. Acute respiratory distress syndrome (ARDS)
ANS: C
Emphysema causes an increase in pulmonary compliance, whereas ARDS and kyphoscoliosis
cause decreases in pulmonary compliance. Asthma attacks cause increase in airway resistance.

REF: pg. 6 | pg. 7

10. Calculate the effective static compliance (Cs) given the following information about a patient
receiving mechanical ventilation: peak inspiratory pressure (PIP) is 56 cm H2O, plateau
pressure (Pplateau) is 40 cm H2O, exhaled tidal volume (VT) is 650 mL, and positive end
expiratory pressure (PEEP) is 10 cm H2O.
a. 14.1 mL/cm H2O
b. 16.3 mL/cm H2O
c. 21.7 mL/cm H2O
d. 40.6 mL/cm H2O
ANS: C
The formula for calculating effective static compliance is Cs = VT/(Pplateau  EEP).

REF: pg. 6 | pg. 7

11. Based upon the following patient information, calculate the patient’s static lung compliance:
exhaled tidal volume (VT) is 675 mL, peak inspiratory pressure (PIP) is 28 cm H2O, plateau
pressure (Pplateau) is 8 cm H2O, and PEEP is set at 5 cm H2O.
a. 0.02 L/cm H2O
b. 0.03 L/cm H2O
c. 0.22 L/cm H2O
d. 0.34 L/cm H2O
ANS: C
The formula for calculating effective static compliance is Cs = VT/(Pplateau  EEP).

REF: pg. 5 | pg. 6

12. A patient receiving mechanical ventilation has an exhaled tidal volume (VT) of 500 mL and a
positive end expiratory pressure setting (PEEP) of 5 cm H2O. Patient-ventilator system checks
