A nurse needs to know if there are any research studies on the maximum length of time that bedridden clients should remain in one position.Which electronic source is most likely to provide this information for the nurse?

A) Computer-assisted-learning
B) Internet
C) CINAHL
D) World Wide Web

CINAHL (Cumulative Index to Nursing and Allied Health Literature) is a database specifically designed for nursing and allied health professionals, and it includes research studies on various topics related to the field. Therefore, it is the most likely source to provide information on the maximum length of time that bedridden clients should remain in one position. The other options are not specific to nursing and may not have as much relevant information.
