As part of a diagnostic workup of a 22-year-old male with recently diagnosed schizophrenia, a neurologist wants to examine the levels of metabolic activity in particular areas of the client's brain
Which of the following diagnostic procedures is the physician most likely to order?
A)
Computed tomography (CT)
B)
Electroencephalography (EEG)
C)
Magnetic resonance imaging (MRI)
D)
Positron emission tomography (PET)
Ans:
D
Feedback:
PET is rooted in the selective brain uptake of radiolabeled isotopes. As such, it can measure brain metabolic activity. CT and MRI offer visualization of structural components, while EEG measures electrical activity.

The nurse is conducting a nutritional assessment of a client's dietary intake
In order to determine if the client is on tract, she compares his intake with the estimated average requirements (EAR) in the Dietary Reference Index (DRI), knowing that the EAR is: 1. The average daily amount of a given nutrient sufficient to meet the nutrient requirement of 97–98% of healthy individuals. 2. The estimated amount of nutrients needed to meet average daily energy needs. 3. The EAR are guidelines for a population rather than an individual. 4. The average daily nutrient intake value that is estimated to meet the requirements of 50% or more of healthy individuals in a life stage and gender group.
