The nurse is caring for a client requiring continuous pulse oximetry readings. How often would the nurse alter the probe site?
1. Every 2 hours
2. Every 4 hours if the probe is an adhesive wraparound sensor
3. Every 4 hours if the probe is a spring-loaded sensor
4. Every 2 hours if the probe is an adhesive wraparound sensor
Correct Answer: 2
Adhesive wraparound sensors should be repositioned every 4 hours. Spring-loaded tension probes should be repositioned every 2 hours.

A researcher is collecting data in a hospital during cardiopulmonary resuscitation. The researcher has devised a data collection form that contains five columns for data entry
During the first three data collection periods, the form works reasonably well, although the researcher has to turn the page over and write on the back. During the fourth, however, the CPR incident occurs in the emergency department and includes many procedures and interventions, and the researcher ends up taking a blank piece of paper and recording data on that. Later, it takes him 40 minutes to unscramble and collate the data and record it properly. What must be done now? a. The researcher will go back to the institutional review board and request permission to use a different form. b. The researcher will design a new form, with the assumption that the next CPR incident will be just as complex as the last was. c. The researcher will continue to use the old form, writing on the back when necessary, and pulling out blank pieces of paper, from time to time, for additional data recording. d. The researcher will decrease the amount of data necessary to record by revising the old study protocol, so that fewer research questions are asked.
Why should a nurse researcher want to limit or eliminate extraneous variables in a study?
a. More research questions would be required to account for the extraneous variables. b. Extensive statistical analysis would be required to justify the presence of extraneous variables. c. Extraneous variables compete with the independent variables as explanations of the study's outcome. d. Manipulation of the extraneous variables increases the risk for researcher bias in the study's outcomes.
