Answer:
<u>In day light.</u>
Explanation:
Color variations of the skin can be conducted in any environment or light source. But for the best results, it is conducted in a day light as it provide best illumination source to detect color variations. Other sources such as lamp light or fluorescent light are narrow spectrum or specific spectrum light providing narrow range of results.
The correct answer is: tighten and contract
This is is the correct
answer because muscle fibers need to first reach an optimal length and
tension ratio or "tighten" in order for the muscle to perform work.
After the muscle has tightened, it can then "contract" which leads to a
decrease in the angle of the joint through force. If the muscle being
used to pull the rope is the bicep on the arm, then the angle between
the forearm and upper arm will decrease, causing the rope to be pulled.
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."
"Alertness and focus" are a variety of answers i would use.
