Explanation:
A patient with an acid-base imbalance has an altered potassium level. The nurse recognizes that the potassium level is altered because ________.
a. Potassium is returned to extracellular fluid when metabolic acidosis is corrected.
b. Hyperkalemia causes an alkalosis that results in potassium being shifted into the cells.
c. Acidosis causes hydrogen ions in the blood to be exchanged for potassium from the cells.
d. In alkalosis, potassium is shifted into extracellular fluid to bind excessive bicarbonate.
c. Acidosis causes hydrogen ions in the blood to be exchanged for potassium from the cells. The potassium level is altered in patients with acid-base imbalances as hydrogen ions are exchanged for potassium between the cells and extracellular fluid during acidosis, and potassium shifts into the cells during alkalosis.
The potassium level is altered in a patient with an acid-base imbalance because acidosis causes hydrogen ions in the blood to be exchanged for potassium from the cells. When the body experiences acidosis, there is an excess of hydrogen ions, leading to a lower pH in the blood. To combat this imbalance, the body will exchange extracellular hydrogen ions for intracellular potassium ions, increasing the level of potassium in the extracellular fluid. This mechanism helps to buffer the blood pH, but it also leads to altered potassium levels, which can have clinical consequences. On the other hand, in conditions of alkalosis, where there is a relative deficit of hydrogen ions, the opposite happens, causing potassium to shift into cells and potentially lead to hypokalemia, which is an abnormally low level of potassium in the blood.

Psychologists use the term ________ to refer to a relatively permanent change in behavior brought about by experience.
Answer:
Learning
Explanation:
Final answer:
The term psychologists use to refer to a relatively permanent change in behavior due to experience is 'learning'. This includes adapting to new knowledge or behaviors and psychological processes modifications. It is embodied by Piaget's concept of 'accommodation', where cognitive schemas are modified through new experiences.
Explanation:
Psychologists use the term learning to refer to a relatively permanent change in behavior brought about by experience. This concept encompasses not only academic knowledge and skills acquired through study but also a variety of changes in psychological processes. For example, adaptations in social behaviors or the development of psychological disorders like PTSD can be forms of learning.
Jean Piaget, a renowned psychologist, described a related concept called accommodation, which occurs when new information or experiences lead to the modification of existing cognitive schemas. This is a specific type of learning that involves changing one's framework of understanding as new knowledge is integrated.
In essence, learning is a change in behavior or knowledge that results from experience, distinguishing it from innate behaviors like reflexes. Learned behaviors are flexible and adaptable, essential attributes that allow individuals and organisms to modify their actions to suit changing conditions and environments.
