The gathering of information regarding a patient's and its associated individual's psychological, physiological, spiritual, and sociological status by a licensed Registered Nurse is known as nursing assessment. It is the initial step in the process of nursing.
In the given case, the nurse should initiate a recommendation to a suitable agency to evaluate the requirement for a home health aide and scheduling a family meeting, which will make sure that a complete assessment for the requirements of the family is made and the suitable assistance is initiated.
Answer:
A) Times of major climate change
Explanation:
The geological time scale is based on major changes in Earth's climate history. This is because of the reason that climate governs the geological processes on Earth. In geology, we study the ages with the help of stratigraphical data where sediment deposition and the fossils it is hosting are the keys to understand the environmental conditions at that particular time. These conditions didn't change significantly unless the climate was changed. An example is the extinction of dinosaurs during K/T boundary event (mass extinction). The most likely reason is the hitting of a meteorite on Earth that changed the climate of Earth in a short period making it least favorable for many organisms to survive.
On the other hand, the occurrence of huge events cannot be used to establish a geological time scale because sometimes, the changes happen more slowly.
Similarly, shifts in the Earth orbits are cyclic however geological time scale doesn't reflect cyclic changes. The same climate can establish in different ages but these events are not used not as a criterion to establish a geological time scale.
In the end, the time span of humans on Earth is very small when compared with the overall geological time scale. Humans record exists from Pleistocene (2,580,000 to 11,700 years ago) to today whereas geological time scale starts in the Archean Eon (4.0 billion to 2.5 billion years ago).
Answer:
Option C
Explanation:
As we know that
Relative humidity (RH) is defined as the ratio of amount of water vapor present in a given sample of air to the maximum amount of water that can be absorbed by the same sample of air to attain saturation at a particular temperature
.
Thus,
Where X represents the current amount of water vapor present in a given sample of air
and Y represents the maximum amount of water that can be absorbed by the same sample of air to attain saturation at a particular temperature
Substituting the given values in above equation we get -
Hence, option C is the correct answer
