  a. positron emission tomography (PET)
  b. computerized tomography (CT)
  c. magnetic resonance imaging (MRI)
  d. electroconvulsive therapy (ECT)

Question 2

  a. It restricts patients to a physical space in order to reduce sensory overload. The goal is to minimize the risk of harm to others while preserving the patient's personal safety and dignity.
  b. It offers safety by removing all potentially harmful objects and allows for the testing of the patient's interpersonal control by gradually decreasing and/or increasing sensory input.
  c. It provides for a carefully protected milieu that offers safety, permeability of sensory input, and only incrementally increased interpersonal relationships.
  d. It prevents patients from harming themselves or others, reduces the need for proprioception, and provides a protective milieu at the risk of sensory deprivation.

Answer to Question 1

A
Positron emission tomography (PET) scanning techniques are not fundamentally different from those used in CT scanning. However, one important addition is that the PET scan requires the injection of a small amount of radioactive isotope that is localized in brain tissue. The PET scan allows the location of that isotope to be traced while a subject performs certain tasks.

Answer to Question 2

A
Seclusion is the use of a fully protective environment with close observation by nursing staff for the purpose of safety or behavior management based on a professional nursing philosophy of concern for human dignity and optimal fulfillment of basic human needs. The scientific rationale for the use of seclusion is based on three principles: containment, isolation, and decrease in sensory input.
