Nursing perception of risk in common nursing practice situations.

As health care organizations seek to be highly reliable, systems that include layers of redundancy have been created to protect patients from harm. Many of these layers of protection are dependent on nurses making a decision to follow or adhere to the human aspects of the process. Because these decisions begin with a perception and identification of risk, understanding what nurses perceive to be a risk to patients is an essential part of designing safer health care systems.

Methods for conducting bioassays using embryos and larvae of Pacific herring, Clupea pallasi.

The rapid decrease of several stocks of Pacific herring, Clupea pallasi, in Puget Sound, Washington, has led to concerns about the effects of industrial and nonpoint source contamination on the embryo and larval stages of this and related forage fish species. To address these concerns, the state of Washington and several industries have funded efforts to develop embryo and larval bioassay protocols that can be used by commercial laboratories for routine effluent testing. This article presents the results of research to develop herring embryo and larval bioassay protocols.
