ONCC Certified Pediatric Hematology Oncology Nurse (CPHON) - Exam Topics Sample Questions

The dynamic system in which primary function would be to ensure the health and well-being of its individual members and the family as a whole would be considered?

Correct Answer:
family
the correct answer is "family."

the family is fundamentally a dynamic system whose primary function involves ensuring the health and well-being of its members individually and collectively. this system is characterized by interdependent relationships where each member influences and is influenced by the others. in essence, the family acts as the first line of support and care, offering both emotional and physical care to its members.

in the context of health and well-being, the family plays a crucial role. it is often the family that provides direct care in times of illness, supports the management of chronic diseases, and promotes healthy behaviors and lifestyles among its members. the role of the family extends to psychological health as well, providing emotional support, fostering resilience, and contributing to the creation of a stable environment.

moreover, the function of a family is not only reactive (responding to health issues as they arise) but also proactive. families often engage in the prevention of health problems through education about health and hygiene, nutritional support, and by encouraging physical activity among its members. in this way, the family system aims to cultivate a foundation of good health and well-being that supports each member.

the effectiveness of a family in fulfilling these roles can significantly impact the overall health outcomes of its members. when a family effectively meets the needs of its members, it can enhance their health and well-being, whereas deficiencies in these family functions can lead to negative health outcomes.

thus, when considering the dynamic system whose primary function is to ensure the health and well-being of its individuals and the family as a whole, the family stands out as the most pivotal. other systems like peers, healthcare teams, or physicians indeed play significant roles in an individual's health ecosystem, but the family is foundational, providing the first layer of support and influence.

The malignant disorder of the blood and blood forming organs which would include the spleen, lymph nodes, and bone marrow would be considered?

Correct Answer:
leukemia


leukemia is a type of cancer that primarily affects the blood and bone marrow but also has implications for other organs involved in the production and function of blood cells, such as the spleen and lymph nodes. this disorder is characterized by the excessive production of abnormal white blood cells, which can impair the body's ability to fight infection, carry oxygen, and perform other critical functions normally handled by blood cells.

in leukemia, the bone marrow (a spongy tissue inside bones) produces a large number of abnormal white blood cells which do not function properly. these cells often crowd out the healthy cells, leading to serious complications over time. depending on the speed of progression and the type of blood cells affected, leukemia is classified into several types, such as acute lymphoblastic leukemia (all), acute myeloid leukemia (aml), chronic lymphocytic leukemia (cll), and chronic myeloid leukemia (cml).

acute lymphoblastic leukemia (all), for instance, is particularly noted for its rapid progression. it primarily affects lymphoid cells, which are a type of white blood cell that plays a vital role in the immune system. all leads to the accumulation of immature lymphoid cells in the bone marrow, blood, and potentially other organs, like the spleen and lymph nodes.

the spleen and lymph nodes are part of the lymphatic system, which helps the body fight infection. in leukemia, these organs may become enlarged as they attempt to filter out the abnormal cells or become infiltrated by them, which can impair their normal function. this enlargement is often one of the first physical signs that a physician might detect during a physical examination.

thus, when considering the question of what malignant disorder includes the spleen, lymph nodes, and bone marrow, leukemia is the appropriate answer. its impact on these critical components of the body's blood-forming and immune systems makes it a complex disease requiring comprehensive treatment, often involving chemotherapy, radiation therapy, or bone marrow transplantation.
