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."
I would go with B. Cave Diving (: skydiving is dangerous and so is free diving

Answer and Explanation:
Tuberculosis is an infectious and transmissible disease that primarily affects the lungs, although it can affect other organs and / or systems. The disease is caused by the Mycobacterium tuberculosis or Koch's bacillus. It is an air spread disease and occurs from the inhalation of aerosols from the airways during the speech, sneezing, or coughing of people with active tuberculosis, who release aerosol-containing particles into the air that contain the bacillus.
With the initiation of treatment, transmission tends to decrease gradually and, generally, after 15 days of treatment, it is greatly reduced. However, control measures should be implemented such as covering the mouth with the arm or handkerchief when coughing, keeping the environment well ventilated and with plenty of sunlight. The bacillus is sensitive to sunlight, and air circulation enables dispersion of infecting particles. Thus, ventilated environments with direct natural light reduce the risk of transmission.
So the program was sucessful if the number of patients decreased, as the disease can be controlled veru easily by that measures controls listed above.
