A nurse is assessing a client's comprehension of a pulmonary function test prior to the procedure. Which of the following client statements indicates to the nurse an understanding of the procedure?

Choice A Reason:
Replacing total parenteral nutrition solution bags every 48 hr is incorrect. Total parenteral nutrition (TPN) solution bags typically need to be replaced more frequently than every 48 hours to prevent bacterial contamination and ensure the integrity of the solution. However, the frequency of bag changes may vary depending on institutional protocols and specific patient needs.
Choice B Reason:
Replacing peripheral IV solution bags every 96 hr is incorrect. Peripheral IV solution bags may be changed less frequently than every 96 hours, as long as the solution remains sterile and the integrity of the infusion system is maintained. However, the frequency of bag changes may vary based on institutional policies and patient-specific factors.
Choice C Reason:
Changing peripheral IV primary tubing every 96 hr is correct. Changing peripheral IV primary tubing every 96 hours is a recommendation consistent with infection control guidelines and helps prevent contamination and bloodstream infections. This practice is cost-effective while ensuring patient safety.
Choice D Reason:
Changing total parenteral nutrition IV tubing every 48 hr is incorrect. Total parenteral nutrition (TPN) IV tubing typically needs to be changed more frequently than every 48 hours to prevent bacterial contamination and ensure the integrity of the TPN solution. However, the frequency of tubing changes may vary depending on institutional protocols and patient-specific factors.

Choice A Reason:
A sufficient supply of personal protective equipment is appropriate. Bioterrorism events can involve the deliberate release of biological agents, such as bacteria, viruses, or toxins, with the intent to cause harm to individuals or populations. In such events, personal protective equipment (PPE) is critical for protecting healthcare workers and first responders from exposure to infectious agents and toxins. Adequate supplies of PPE, including masks, gloves, gowns, and eye protection, are essential to ensure the safety of healthcare workers and to prevent the spread of infection.
Choice B Reason:
A network for communication between staff members and families, is important for coordinating care and providing updates during a disaster, but it is not the highest priority when addressing immediate safety concerns related to a bioterrorism event.
Choice C Reason:
A mental health specialist on the response team, is important for providing support to individuals affected by the disaster, but it is not the highest priority during the initial response phase focused on safety and containment.
Choice D Reason:
A system for tracking client information, is important for maintaining continuity of care and tracking patient outcomes, but it is not the highest priority in the immediate response to a bioterrorism event when protecting healthcare workers and preventing further spread of infection is paramount.
