The nurse recognizes that one primary difference between normal and cancer cells is related to regulated cell death that normal cells undergo as part of the regular cell cycle. What is the term for this change in cellular function?

Contact inhibition

Anaplasia

Apoptosis

Anchorage dependence

Answer and Explanation

The Correct Answer is C

A. Contact inhibition refers to the process where normal cells stop growing when they come into contact with other cells. Cancer cells often lose this ability and continue to proliferate despite contact.
B. Anaplasia refers to the loss of differentiation in cancer cells, making them look less like the normal cells from which they originated. This is not directly related to regulated cell death.
C. Apoptosis is the term for programmed cell death, a normal process where cells that are damaged or no longer needed die in a controlled manner. Cancer cells often evade apoptosis, allowing them to survive and proliferate uncontrollably.
D. Anchorage dependence refers to the need for cells to be anchored to a surface to divide. Cancer cells often lose anchorage dependence, allowing them to grow independently.

Correct Answer is A

Explanation

A. Trauma-related disorders, such as PTSD or acute stress disorder, can develop after experiencing or witnessing a traumatic event, even if there is no physical harm. Events such as violence, natural disasters, abuse, or accidents can be triggers.
B. Physical harm is not required for a trauma-related disorder to develop. Psychological and emotional trauma alone can be sufficient.
C. While neurobiological factors may play a role in how trauma affects the brain, trauma-related disorders are primarily triggered by traumatic experiences, not solely by a chemical imbalance.
D. Although genetic predispositions may influence vulnerability, people are not simply born with trauma-related disorders; they develop as a response to traumatic events.

A. "The ability to solve novel problems remains stable during older adulthood." B. "Long term memory worsens in older adulthood" C. "Short-term memory improves in older adulthood." D. "The ability to learn continues throughout life."

Correct Answer is D

Explanation

A. While problem-solving ability may decline slightly with age, the ability to solve novel problems does not necessarily remain entirely stable and can be impacted by other factors such as cognitive health and education.
B. Long-term memory does not necessarily worsen in older adulthood. It is often short-term memory that experiences more noticeable decline. Long-term memory for events and information learned in the past may remain relatively intact.
C. Short-term memory tends to decline with age, making it more difficult to retain new information or recall it quickly.
D. The ability to learn continues throughout life, though it may require more effort or different strategies, such as repetition or mnemonic devices. Older adults are capable of learning new skills and information, even though the process may change with age.
