Which of the following best describes a neuroblastoma?

Choice A reason: This choice is incorrect because a 1-year-old toddler who has roseola and a temperature of 39° C (102.2° F) is not the most urgent case to assess. Roseola is a viral infection that causes a rash on the trunk and limbs, followed by a high fever that lasts for several days. It usually affects infants and young children and is self-limiting.
The fever can be managed by giving antipyretics such as acetaminophen or ibuprofen, and by providing fluids and comfort measures. The fever does not indicate any serious complication or threat to life.

Choice B reason: This choice is incorrect because a 4-year-old child who has asthma and an O2 sat of 97% is not the most urgent case to assess. Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways, leading to wheezing, coughing, chest tightness, or shortness of breath. It may be triggered by allergens, irritants, exercise, or infections. The O2 sat is a measure of oxygen saturation in the blood, which indicates how well oxygen is delivered to the tissues. A normal O2 sat range is 95% to 100%, so an O2 sat of 97% indicates that the child has adequate oxygenation and is not in respiratory distress.

Choice C reason: This choice is correct because a 10-year-old child who has sickle cell anemia and reports severe chest pain is the most urgent case to assess. Sickle cell anemia is a genetic disorder that causes the red blood cells to become sickle-shaped and clump together, blocking the blood flow and oxygen delivery to the organs and tissues. It may cause severe pain in the chest, abdomen, joints, or bones, as well as symptoms such as pallor, jaundice, fatigue, or shortness of breath. Severe chest pain may indicate acute chest syndrome, which is a life-threatening complication of sickle cell anemia that involves infection or infarction of the lungs. It may cause fever, cough, hypoxia, or respiratory failure. Therefore, assessing and treating this child is a priority to prevent further damage and death.

Choice D reason: This choice is incorrect because a 7-year-old child who has diabetes insipidus and a urine specific gravity of 1.016 is not the most urgent case to assess. Diabetes insipidus is a rare disorder that affects the balance of fluids in the body. It causes the kidneys to produce large amounts of dilute urine, leading to polyuria, polydipsia, dehydration, or electrolyte imbalance. It may be caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its action. The urine specific gravity is a measure of urine concentration, which indicates how well the kidneys are functioning. A normal urine specific gravity range is 1.005 to 1.030, so a urine specific gravity of 1.016 indicates that the child has normal urine concentration and is not dehydrated.

Choice A reason: This choice is incorrect because the loss of a parent is not the priority risk factor for suicide completion. Loss of a parent is a stressful life event that may cause grief, depression, or anxiety in an adolescent, but it does not necessarily increase the risk of suicide completion. However, the loss of a parent may be associated with other risk factors such as low self-esteem, poor coping skills, or social isolation, which can contribute to suicidal ideation or behavior.
Choice B reason: This choice is incorrect because a history of substance abuse is not the priority risk factor for suicide completion. History of substance abuse is a behavioral problem that may impair the judgment, mood, or impulse control of an adolescent, but it does not necessarily increase the risk of suicide completion. However, a history of substance abuse may be associated with other risk factors such as mental illness, family conflict, or legal trouble, which can contribute to suicidal ideation or behavior.
Choice C reason: This choice is correct because a previous suicide attempt is the priority risk factor for suicide completion. Previous suicide attempt is a clear indicator of suicidal intent and capability, and it increases the likelihood of future attempts and completion. According to the American Foundation for Suicide Prevention (AFSP), about 40% of people who die by suicide have a history of previous attempts. Therefore, assessing and addressing previous suicide attempts is essential to prevent further harm and save lives.
Choice D reason: This choice is incorrect because active psychiatric disorder is not the priority risk factor for suicide completion. Active psychiatric disorder is a mental health condition that may affect the thoughts, feelings, or behaviors of an adolescent, but it does not necessarily increase the risk of suicide completion. However, active psychiatric disorder may be associated with other risk factors such as hopelessness, helplessness, or isolation, which can contribute to suicidal ideation or behavior.
