Answer:
<u><em>fixed-ratio</em></u><em>; </em><u><em>variable-ratio
</em></u>
Explanation:
The fixed ratio is a reinforcement method. <em>Reinforcement is given in this method after a number of responses have been completed. </em>
<em>The number of responses expected continues to be constant.</em>
A variable-ratio schedule is a reinforcement schedule where an unknown number of responses reinforce the response. <em>This routine produces a reliable, high response rate. </em>
<em>Betting and casino activities are great examples of a payout dependent on a schedule for a variable ratio.</em>

Answer:
PICO is a mnemonic system that is much used in evidence-based practice both in Medicine and Nursing. This system allows a researcher in a medical field to evaluate all aspects of a situation, or health condition, being studied and respond to all the necessary questions in an organized and integral form. PICO, stands for the following: P: patient, problem or population, I: Intervention, C: Comparisson, control, and O: Outcomes.
In the case of this question, the nurse researcher wishes to ascertain the effectiveness of replacing intravenous catheters in patients with a frequency of 72 hour-intervals between changes in diminishing infection rates due to this nursing procedure. In order to fully research the validity of such a question, of the ensuing experimentation, observation and gathering of data, and the release of valid results, this researcher will use PICO as her guiding framework. As the question requests, then, the O in this system would apply to the expected result, or the outcome, expected from applying the thesis of the researcher. That would be: "the decrease infection rates."
