Questions About the Respiratory System With Answers Questions
Question 1 of 5
In the process of transport of CO2 which phenomenon occurs between RBCs and plasma
Correct Answer: C
Rationale: The correct answer is C: Chloride shift. During the transport of CO2, carbonic anhydrase in RBCs converts CO2 to bicarbonate ions. To maintain electrochemical neutrality, chloride ions move into RBCs as bicarbonate ions move out into plasma (Chloride Shift). Osmosis (A) involves the movement of water across a semi-permeable membrane, not relevant to CO2 transport. Adsorption (B) refers to the adhesion of molecules to a surface, not a process between RBCs and plasma in CO2 transport. Absorption (D) typically involves the uptake of substances into a bulk material, not applicable to the interaction between RBCs and plasma in CO2 transport.
Question 2 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 3 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 4 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.
