Which statement is true about recovered tissue?
It can be processed and stored for up to ten years.
Recovered pediatric heart valves can be used in the elderly.
A transplanted kidney must be replaced every year.
Because the cause of death of the donor is known, testing for disease is not necessary.
The Correct Answer is B
It can be processed and stored for up to ten years: The storage duration of recovered tissue depends on the specific type of tissue and the storage methods. While some tissues can be stored for extended periods, the statement is overly generalized and may not apply to all types of tissue.
Recovered pediatric heart valves can be used in the elderly: This statement is true. Heart valves from pediatric donors can often be used in elderly patients. The size and quality of the valves are important factors, and pediatric valves can be resized for transplantation into older recipients.
A transplanted kidney must be replaced every year: This statement is false. Kidney transplants are intended to be permanent solutions. While there can be complications or issues that might require medical attention, replacing the kidney every year is not a standard or necessary practice.
Because the cause of death of the donor is known, testing for disease is not necessary: This statement is false. Even if the cause of death is known, rigorous testing for diseases, especially communicable diseases, is essential to ensure the safety of the transplant recipient. Testing helps prevent the transmission of infections from the donor to the recipient.

Correct Answer is C
Explanation
The client's spouse: While the spouse may be a close family member and have significant input into the client's medical decisions, the ultimate authority for decisions like a DNR order rests with the client, assuming they are competent to make their own decisions.
The client's only child: Similar to the spouse, a child can have an emotional and supportive role in the decision-making process, but unless legally designated as the healthcare proxy or power of attorney for healthcare decisions, they do not typically have the legal authority to make decisions for a competent adult.
The client: In the context of medical decision-making, the principle of patient autonomy is fundamental. If the client is competent and capable of making decisions, their wishes and consent are paramount. In the case of a DNR order, it should be discussed thoroughly with the client, ensuring they understand the implications, risks, and benefits before making an informed decision.
Any close blood-related relative: In general, the authority to make medical decisions, including DNR orders, is not automatically granted to any blood-related relative. The client or their legally appointed representative (such as a healthcare proxy) usually holds this authority.
Correct Answer is B
Explanation
They are not used extensively in high-level nursing research:This statement is not accurate. Middle-range nursing theories are frequently utilized in nursing research. They provide a bridge between grand theories (which are broad and abstract) and specific nursing practice situations, making them valuable in research settings.
They form the foundation for the current evidence-based practice movement: This statement is accurate. Middle-range nursing theories are often the basis for evidence-based practice. They offer practical frameworks and specific concepts that can be tested and applied in clinical settings, contributing significantly to the development of evidence-based nursing practices.
They do not focus on abstract concepts: This statement is not entirely accurate. While middle-range theories are more specific and focused than grand theories, they can still include abstract concepts. However, these concepts are more directly related to specific nursing phenomena, making them more applicable and tangible for nursing practice.
They are often developed into major nursing theories: This statement is not accurate. Middle-range nursing theories are distinct from major nursing theories. Major nursing theories are broader and more abstract, often encompassing multiple aspects of nursing practice. Middle-range theories, on the other hand, are more focused and specific, addressing particular issues or phenomena within nursing practice.
