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 A
Explanation
Choice A rationale:
Weight gain is the most objective and reliable indicator of improved nutritional status in patients with HIV-II and wasting syndrome. It directly reflects an increase in lean body mass, which is essential for restoring physical strength, immune function, and overall health.
A weight gain of 2 lb (1 kg) in a month is considered a clinically significant improvement for this patient population. It demonstrates that the patient is consuming more calories than they are expending, leading to a positive energy balance and tissue growth.
Other assessment findings, such as food intake, food choices, and oral discomfort, can be subjective and influenced by various factors, such as appetite, taste changes, nausea, fatigue, and psychosocial issues. While they provide valuable information about the patient's nutritional status, they do not directly measure the actual improvement in body composition.
Choice B rationale:
Consuming 90% of meals and snacks is a positive sign that the patient is adhering to their dietary recommendations. However, it does not guarantee that they are consuming enough calories to promote weight gain. The patient's individual energy needs and the nutritional content of the meals and snacks must be considered.
Choice C rationale:
Choosing high-protein foods is important for building and repairing tissues, but it does not ensure adequate overall caloric intake. The patient may still be experiencing a calorie deficit if they are not consuming enough total calories, even if they are focusing on protein-rich foods.
Choice D rationale:
Decreased oral discomfort can facilitate better food intake, but it does not directly reflect weight gain or improved nutritional status. The patient may still have challenges with appetite, nausea, or other factors that hinder their ability to consume enough calories.
Correct Answer is B
Explanation
Choice A rationale:
While a young patient who lives alone may need some assistance with post-discharge care, they have nearby family and friends who can likely provide this support. This patient's situation does not present the same level of complexity and risk as the other patients described in the options.
The presence of nearby family and friends can offer practical and emotional support, helping with tasks such as transportation, meal preparation, and medication management. This social support network can play a crucial role in ensuring a smooth transition from the hospital to home.
Additionally, the patient's young age suggests a higher likelihood of physical and cognitive abilities that can facilitate self-care and adherence to discharge instructions.
Choice B rationale:
The older adult who lives alone and has memory loss has the greatest need for the nurse to consult with other members of the healthcare team regarding post-discharge care. This patient's situation presents several significant challenges that necessitate a collaborative approach to ensure safety and well-being:
Memory loss: The patient's memory loss may impair their ability to follow discharge instructions, manage medications, and maintain personal safety. This raises concerns about potential medication errors, missed appointments, and risks of falls or accidents.
Living alone: The patient's lack of immediate support at home further compounds these risks. Without someone to provide reminders, assistance with tasks, or monitoring for changes in health status, the patient's vulnerability increases.
Potential for social isolation: Living alone with memory loss can also lead to social isolation, which can negatively impact mental and physical health.
Choice C rationale:
While a married young adult who is the primary caregiver for children may face challenges in balancing their own recovery with caregiving responsibilities, they have a spouse who can provide support and assistance. This patient's situation does not present the same degree of risk as the older adult with memory loss living alone.
Choice D rationale:
The middle-aged patient who has undergone knee replacement and requires physical therapy will need support and guidance, but their needs are primarily focused on physical rehabilitation and pain management. These needs can often be addressed through standard discharge planning and coordination with physical therapy services.
