Answer to Question 1

C
In the formal operations period, adolescents and young adults begin to think about such subjects as achieving world peace, finding justice, and seeking meaning in life. Asking about a presidential election demonstrates that the adolescent is concerned about political issues that affect others besides her. Hitting would be a common schema during the sensorimotor stage of development. Using play to learn about the environment is indicative of the preoperational stage. During the concrete operations stage (ages 6 to 12 years), children are able to coordinate two concrete perspectives in social and scientific thinking, such as understanding the difference between hiding and melting.

Answer to Question 2

A
The cuff fits over clothing. However, the reliability of stationary machines is limited. Electronic blood pressure measurement is not recommended with irregular heart rates or when blood pressure is less than 90 mm Hg systolic.
