The normal life expectancy for 50% of patients ith amyotropic lateral sclerosis (ALS) is:
- A. 3 years
- B. 10 years
- C. 5 years
- D. 20 years
Correct Answer: A
Rationale: Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive and fatal neurodegenerative disease that affects the nerve cells in the brain and spinal cord. The average life expectancy for individuals with ALS is around 2 to 5 years from the time of diagnosis. Therefore, the normal life expectancy for 50% of patients with ALS would be closer to the midpoint of this range, which is approximately 3 years. While some individuals may live longer than 3 years with ALS, for 50% of patients, this would be a reasonable estimate based on the typical progression of the disease.
Which type of parenting style is associated with children who rank higher on many measures of social and cognitive development?
- A. Warm, responsive, positive
- B. Neutral, rigid, critical
- C. Absent, unstructured, negative
- D. Cold, neglectful, negative
Correct Answer: A
Rationale: Research has shown that a warm, responsive, and positive parenting style is associated with children who rank higher on many measures of social and cognitive development. This style promotes secure attachment, emotional regulation, and overall well-being in children. In contrast, parenting styles characterized by neutrality, rigidity, negativity, or neglect have been linked to poorer outcomes in children's development. Understanding different parenting styles can help professionals tailor interventions to support families effectively and respectfully.
