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:
Affiliation with a medical or nursing school can offer some benefits, but it's not the most crucial factor to consider when seeking a new job.
Nurses in these facilities may have opportunities for professional development and involvement in research, but these benefits might not be available to all nurses.
The quality of the work environment, staffing levels, and support for nurses can vary significantly in facilities affiliated with schools.
Prioritizing Magnet status ensures a focus on nursing excellence and a commitment to providing a supportive work environment.
Choice B rationale:
Having the latest technology can be appealing, but it doesn't guarantee a positive work experience for nurses.
The most important factors for job satisfaction and quality patient care are often related to the work environment, staffing levels, and leadership support.
Magnet hospitals prioritize these factors, leading to better outcomes for both nurses and patients.
Choice C rationale:
Inquiring about nurse-patient ratios is essential, but it's not the only indicator of a positive work environment.
Magnet hospitals typically have favorable nurse-patient ratios, but they also excel in other areas that contribute to job satisfaction and quality care.
These areas include: shared governance, leadership support, professional development opportunities, and a focus on evidence-based practice.
Choice D rationale:
Magnet status is the highest recognition a hospital can achieve for nursing excellence.
It signifies a commitment to: quality patient care, positive work environments for nurses, professional development, and shared governance.
Research consistently demonstrates that Magnet hospitals have: lower nurse turnover rates, higher patient satisfaction scores, and better patient outcomes.
Seeking employment in a Magnet hospital is the most beneficial advice for a nurse looking for a job that prioritizes nursing excellence, job satisfaction, and quality patient care.
Correct Answer is ["A","C","D","E"]
Explanation
Choice A rationale:
Prednisone:
Corticosteroid that suppresses the immune system: It's crucial to consult with the primary healthcare provider (PCP) because prednisone can impair wound healing and increase the risk of infection after surgery. The PCP may need to adjust the dosage or temporarily discontinue prednisone prior to surgery.
Potential for adrenal insufficiency: Abrupt cessation of prednisone can lead to adrenal insufficiency, a life-threatening condition. The PCP will provide guidance on how to taper the medication safely before surgery.
Interaction with anesthesia: Prednisone can interact with certain anesthetic agents, potentially increasing the risk of complications. The PCP and anesthesiologist will need to coordinate care to ensure safe medication management during surgery.
Choice B rationale:
Metoprolol:
Beta-blocker that lowers blood pressure and heart rate: While metoprolol is generally safe to continue before surgery, it's still essential to inform the PCP and anesthesiologist about its use. They will monitor heart rate and blood pressure closely during and after surgery, as metoprolol can interact with certain medications used during the procedure.
Choice C rationale:
Warfarin:
Blood thinner that prevents blood clots: Warfarin requires careful management around surgery due to its significant bleeding risk. The PCP will typically recommend holding warfarin for several days before surgery to allow for normalization of blood clotting. They may also bridge with a shorter-acting anticoagulant if necessary.
Potential for bleeding complications: If warfarin is not managed appropriately, it can lead to excessive bleeding during or after surgery. The PCP will closely monitor the patient's INR (international normalized ratio), a measure of blood clotting, to ensure it's within the safe range for surgery.
Choice D rationale:
Insulin:
Hormone that regulates blood sugar: Patients with diabetes who take insulin require careful blood sugar control around surgery to prevent complications. The PCP will provide specific instructions on how to adjust insulin doses before, during, and after surgery, as insulin needs often change due to the stress of surgery and the impact of anesthesia.
Risk of hypoglycemia and hyperglycemia: Both low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) can have serious consequences during and after surgery. The PCP will work with the patient to manage blood sugar levels and prevent these complications.
Choice E rationale:
Phenytoin:
Anticonvulsant medication that controls seizures: Phenytoin has a narrow therapeutic window, meaning that blood levels must be closely monitored to ensure efficacy and prevent toxicity. Surgery can affect phenytoin levels, so the PCP will likely recommend checking a blood level before surgery and adjusting the dose as needed.
Potential for drug interactions: Phenytoin interacts with many medications, including some commonly used during surgery. The PCP will need to review the patient's medication list carefully and make any necessary adjustments to prevent interactions.
Choice F rationale:
Omega-3 fatty acid:
Generally safe to continue before surgery: Omega-3 fatty acids are not known to have significant interactions with medications used during surgery or to pose risks for wound healing or bleeding. However, it's always best to inform the PCP about any supplements being taken.
