A nurse is learning the difference between normal cells and benign tumor cells. What information does this include?
Benign tumors have lost their cellular regulation from contact inhibition.
Growing in the wrong place or time is typical of benign tumors.
Benign tumors grow through invasion of other tissue.
The loss of characteristics of the parent cells is called anaplasia.
The Correct Answer is B
Choice A rationale:
Contact inhibition is a normal mechanism that regulates cell growth. When normal cells come into contact with each other, they stop growing. This prevents uncontrolled growth and the formation of tumors.
Benign tumor cells do not typically lose contact inhibition. They still respond to contact signals from neighboring cells and stop growing when they come into contact with each other.
However, they may grow in an uncontrolled manner due to other factors, such as mutations in genes that regulate cell growth.
Choice C rationale:
Invasion is a characteristic of malignant (cancerous) tumors, not benign tumors. Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.
Benign tumors, on the other hand, are localized and do not invade surrounding tissues. They may grow and compress nearby tissues, but they do not spread.
Choice D rationale:
Anaplasia is a term used to describe the loss of differentiation of cells in a tumor. This means that the cells no longer resemble the normal cells from which they originated.
Anaplasia is a characteristic of malignant tumors, not benign tumors. Benign tumor cells typically retain some of the characteristics of the parent cells.

Correct Answer is D
Explanation
Choice A rationale:
While working in a facility affiliated with a medical or nursing school can offer opportunities for professional development and collaboration, it is not the most important factor to consider when choosing a new job.
Affiliation with a school does not guarantee a positive work environment, strong nursing leadership, or a commitment to quality patient care, which are all hallmarks of Magnet hospitals.
It's essential to consider other factors that directly impact job satisfaction, patient outcomes, and overall nursing excellence.
Choice B rationale:
Having the latest technology can be beneficial, but it does not ensure a supportive work environment or a high standard of nursing care.
Technology is only one aspect of a hospital's operations, and it should not be the primary focus when making a career decision. It's crucial to prioritize factors that directly influence the quality of nursing practice and patient outcomes.
Choice C rationale:
Inquiring about nurse-client ratios is important, as it can provide insight into the workload and staffing levels at a hospital. However, it's not the most comprehensive indicator of a hospital's commitment to nursing excellence.
Magnet status, in contrast, signifies a broader commitment to quality nursing care, professional development, and positive work environments.
Choice D rationale:
Magnet status is a prestigious designation awarded by the American Nurses Credentialing Center (ANCC) to hospitals that demonstrate excellence in nursing care, leadership, and innovation.
Magnet hospitals are known for:
Attracting and retaining highly qualified nurses Fostering a culture of collaboration and teamwork Investing in professional development and growth
Promoting evidence-based practice and quality improvement Demonstrating outstanding patient outcomes
Seeking employment at a Magnet hospital is strongly recommended for nurses who prioritize professional growth, job satisfaction, and the delivery of exceptional patient care.
Correct Answer is C
Explanation
Step 1 is (250 mL ÷ 90 min) × 10 gtt/mL. Step 2 is 2.78 mL/min × 10 gtt/mL. Step 3 is 27.78 gtt/min. Step 4 is approximately 28 gtt/min.
Final calculated answer: 28 gtt/min.
