Question 3 of 5

UTI 118 Practice Exam II The methotrexate drug used to treat :

A. child with thalassemia B. child with hemophilia C. child with leukemia D. child with sickle anemia

Correct Answer: C

Rationale: Methotrexate is a chemotherapy medication that is commonly used in the treatment of various types of cancers, including leukemia. Leukemia is a cancer of the blood and bone marrow that affects the white blood cells. Methotrexate works by interfering with the growth and division of cancer cells, thereby helping to slow down or stop the progression of the disease. It is not typically used to treat thalassemia, hemophilia, or sickle cell anemia, as these conditions are not cancers and require different types of treatment approaches.

Question 4 of 5

Which is descriptive of bulimia during adolescence?

A. Strong sense of control over eating behavior B. Feelings of elation after the binge-purge cycle C. Profound lack of awareness that the eating pattern is abnormal D. Weight that can be normal, slightly above normal, or below normal

Correct Answer: C

Rationale: During adolescence, individuals with bulimia often have a profound lack of awareness that their eating pattern is abnormal. This lack of awareness can be attributed to various factors, such as societal pressures, distorted body image, and the normalization of disordered eating behaviors within their social circle. Adolescents with bulimia may not recognize their behaviors as problematic or may rationalize them as a means of coping with stress or controlling their weight. This lack of insight can make it challenging for them to seek help or receive proper treatment for their condition.

The priority interventions in this case should focus on preventing the progression of DVT and reducing the risk of pulmonary embolism.
