A patient is admitted for a lumbar laminectomy. The nurse realizes that which of the following portion of the vertebra will be removed?
1. pedicles that attach the arch to the body
2. spinous process
3. roof of the arch
4. cartilage
3
Rationale: Each vertebra consists of a body that is anterior and an arch that is posterior. The arch section is composed of two pedicles that attach the arch to the body and two laminae that form the roof of the arch. The site where the patient will have surgery is to the roof of the arch of the vertebra. The spinous process is located at the rear of the vertebrae. Cartilage is not a part of the vertebra.

How does an ANOVA differ from a t test of independent samples?
1. An ANOVA allows the comparison of mean scores between and among two or more groups. This test notes that a difference is found, if there is one, but not where the difference lies. 2. An ANOVA is a much higher level test and has no comparison to a t test. 3. An ANOVA compares the means of two or more groups on the dependent measure but an independent t test compares pre- and post scores. 4. An ANOVA gives the reader information about the population of interest but not about the sample in a particular study.
