Module 6 Knowledge Check

A ten-year-old boy is brought to clinic by his mother who states that the boy has been listless and not eating. She also notes that he has been easily bruising without trauma as he says he is too tired to go out and play. He says his bones hurt sometimes. Mother states the child has had intermittent fevers that respond to acetaminophen. Maternal history negative for pre, intra, or post-partum problems. Child’s past medical history negative and he easily reached developmental milestones. Physical exam reveals a thin, very pale child who has bruises on his arms and legs in no particular pattern. The APRN orders complete blood count (CBC), and complete metabolic profile (CMP). The CBC revealed Hemoglobin of 6.9/dl, hematocrit of 19%, and platelet count of 80,000/mm3. The CMP demonstrated a blood urea nitrogen (BUN) of 34m g/dl and creatinine of 2.9 mg/dl. The APRN recognizes that the patient appears to have acute leukemia and renal failure and immediately refers the patient to the Emergency Room where a pediatric hematologist has been consulted and is waiting for the boy and his mother. The diagnosis of acute lymphoblastic leukemia (ALL) was made after extensive testing.

Question 1 of 2:

What is ALL?
Selected Answer:
ALL is a malignant bone marrow disease where there is a proliferation of early lymphoid precursors that replace the normal bone marrow hematopoietic cells. It is the most common type of leukemia in the US and cancer in children. The malignant cells (lymphoblasts) get arrested in the early development stages, which is caused by abnormal gene expression following abnormalities in the number of chromosomes or translocations of chromosomes. When the lymphoblasts proliferate, the number of normal elements in the bone marrow which produce other lines of blood cells decreases.  This explains why most patients usually present with thrombocytopenia, anemia, and neutropenia. In other instances, the lymphoblasts can also infiltrate beyond the bone marrow, to the lymph nodes, liver, and spleen, causing enlargement.
Correct Answer:
Acute lymphoblastic leukemia (ALL) is a malignant (clonal) disease of the bone marrow in which early lymphoid precursors proliferate and replace the normal hematopoietic cells of the marrow. ALL is the most common type of cancer and leukemia in children in the United States.

The malignant cells of acute lymphoblastic leukemia (ALL) are lymphoid precursor cells (ie, lymphoblasts) that are arrested in an early stage of development. This arrest is caused by an abnormal expression of genes, often as a result of chromosomal translocations or abnormalities of chromosome number. NURS 6501 Knowledge Check Psychological Disorders

These aberrant lymphoblasts proliferate, reducing the number of the normal marrow elements that produce other blood cell lines (red blood cells, platelets, and neutrophils). Consequently, anemia, thrombocytopenia, and neutropenia occur, although typically to a lesser degree than is seen in acute myeloid leukemia. Lymphoblasts can also infiltrate outside the marrow, particularly in the liver, spleen, and lymph nodes, resulting in enlargement of the latter organs.

 In Module 7, you will analyze processes related to women’s and men’s health, infections, and hematologic disorders through case study analysis. To do this, you will analyze alterations in the relevant systems and the resultant disease processes. You will also consider patient characteristics, including racial and ethnic variables, which may impact physiological functioning and altered physiology.

Week 10 Knowledge Check: Women’s and Men’s Health, Infections, and Hematologic Disorders

In the Week 10 Knowledge Check, you will demonstrate your understanding of the topics covered during Module 7. This Knowledge Check will be composed of a series of questions related to specific scenarios provided. It is highly recommended that you review the Learning Resources in their entirety prior to taking the Knowledge Check, since the resources cover the topics addressed. Plan your time accordingly.

Week 9: Concepts of Psychological Disorders

Among the many risk factors for mental disorders are genetics and other pathophysiological factors. While other factors, such as environmental factors or substance abuse, can also have an impact, it is important to recognize the connections between biological factors and psychological disorders.

Ranging from anxiety to schizophrenia, psychological disorders offer unique challenges in diagnosis and treatment. Clearly, the presence of these disorders can be life-altering for patients, but they can also significantly impact families and other loved ones.  NURS 6501 Knowledge Check Psychological Disorders

This week, you examine fundamental concepts of psychological disorders. You explore common psychological disorders, and you apply the key terms and concepts that help communicate the pathophysiological nature of these issues to patients.
