Questions About the Respiratory System With Answers Questions
Question 1 of 5
In mammals, the body cavity is partitioned into thoracic and abdominal parts by
Correct Answer: D
Rationale: The correct answer is D: Diaphragm. The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities in mammals. It contracts during inhalation, expanding the thoracic cavity and allowing the lungs to fill with air. This physiological function clearly demonstrates that the diaphragm is the structure responsible for partitioning the body cavity. A: Liver - The liver is located in the abdominal cavity and does not partition the thoracic and abdominal cavities. B: Lungs - Lungs are organs within the thoracic cavity but do not partition the two cavities. C: Ribs - Ribs protect the thoracic organs but do not partition the body cavity into thoracic and abdominal regions.
Question 2 of 5
A nurse prepares a client who is scheduled for a bronchoscopy with transbronchial biopsy procedure at 9:00 AM (0900). What actions would the nurse NOT take?
Correct Answer: A
Rationale: Correct Answer: A - Provide a clear liquid breakfast. Rationale: Preparing a client for a bronchoscopy with transbronchial biopsy involves NPO (nothing by mouth) after midnight to prevent aspiration during the procedure. Providing a clear liquid breakfast contradicts the NPO status required. Summary: - B: Verifying informed consent is essential to ensure the client understands the procedure and consents to it. - C: Documenting allergies is important to prevent any adverse reactions during the procedure. - D: Reviewing laboratory results is necessary to ensure the client's readiness for the procedure.
Question 3 of 5
A nurse cares for a client who is scheduled for a total laryngectomy. What action would the nurse take prior to surgery?
Correct Answer: C
Rationale: The correct answer is C because assisting the client to choose a communication method is crucial before a total laryngectomy surgery as it will help in ensuring effective communication post-surgery. This step is essential to address the potential communication challenges the client may face after the laryngectomy. Assessing airway patency, breathing, and circulation (Choice A) is important but typically occurs as part of routine preoperative assessments and is not specific to laryngectomy. Administering pain medication (Choice B) is not a priority before surgery and should be done as per the prescribed protocol post-surgery. Ambulating the client (Choice D) is not directly related to the specific needs of a client undergoing a total laryngectomy.
Question 4 of 5
A nurse admits a client from the emergency department. Client data are listed below: History Physical Assessment Laboratory Values ° 70 years of age ° Crackles and rhonchi heard ° WBC 5
Correct Answer: A
Rationale: The correct answer is A because the client's presentation suggests an acute respiratory issue, likely pneumonia. The client has crackles and rhonchi, low WBC count, and new onset dyspnea and cough. The priority is to assess oxygenation (PaO2 of 85 mm Hg), which is crucial in pneumonia. The client is on insulin, so blood glucose monitoring is vital. The other choices are not the priority at this moment: B is not the priority until oxygenation is assessed, C is premature without a confirmed diagnosis, and D can be done after prioritizing oxygenation.
Question 5 of 5
How does nosocomial pneumonia occur?
Correct Answer: A
Rationale: The correct answer is A. Nosocomial pneumonia specifically occurs in healthcare settings, often due to exposure to pathogens in hospitals or clinics. B (immunocompromised host) increases susceptibility but is not the defining feature. C (community setting) refers to community-acquired pneumonia. D (within 48 hours) applies to hospital-acquired pneumonia but not all nosocomial cases.
