what is the difference between a threshold dose-response curve and a non-threshold dose-response curve

Answers

Answer 1
Threshold response curve is a point at which a biologic response occurs, so this implies that there is a "safe" amount of dose to be delivered. It starts at a point greater than "0" on the graph.

Non-threshold response curve is described as any radiation exposure can be harmful and cause a response in the body. It implies that there is no safe level of exposure. It starts at "0" on the graph.

Which of the following best describes psychodynamic perspective?

Answers

The term "psychodynamics" is usually understood as movement, unfolding, growth and decay, interaction and struggle of forces within the human psyche. Then the psychodynamic approach is an approach according to which the processes that are visible to a person, occurring in his psyche, are determined not by external circumstances, not by the mind or will of a person, but by the independent dynamics (interaction and struggle) of forces inside the psyche.

The psychodynamic approach proceeds from the assumption that the human psyche has its own movements and interactions of energies that cannot be reduced to physiological or social influences.

K. Jung, A. Adler, O. Rank, G. Sullivan, K. Horney, E. Fromm and many others worked in the psychodynamic approach. Today, in practical psychology, within the framework of these approaches, there are (among the most famous schools and directions) transactional analysis, psychodrama (as its variety - systemic constellations) and body-oriented psychotherapy. The desire for superiority, an inferiority complex are also concepts of the psychodynamic approach. Domestic personality-oriented reconstructive psychotherapy based on the psychology of relations V.N. Myasishchev - a kind of psychodynamic psychotherapy. Existential-humanistic psychotherapy - similarly. If you list all schools and directions, then the list is as follows →

The psychodynamic approach does not always give clear answers about the causes of what is happening and the patterns of flow, we are often satisfied with general indications of the directions for the search for such mechanisms. If over and over again, sometimes in a dream, sometimes in reality, strange images and memories pop up, as if we are standing on the edge of a cliff and cannot decide to take a step forward, although we feel that we may have wings - we can assume that such pictures may be associated with such and such repressed desires. Understanding when and why you suppressed these desires and what these suppressed desires are doing to you now, you find yourself inside the psychodynamic approach.

The psychodynamic approach admits that some aspects of our behavior, in principle, cannot receive simple explanations.

The dynamics of internal energies is not necessarily deep, it can lie on the surface, be elementary for understanding. "Action is equal to reaction", "The more you push, the more resistance..."

It is important to understand that simple speakers are not synonymous with "unimportant". The dynamics of distraction, or patterns of fatigue, are of the utmost importance, although it is difficult to classify them as deep dynamics.

On the other hand, deep dynamics is not a synonym for something necessarily important and significant. During auto-training of the highest level, color discharges begin to occur in the human mind. There is some regularity in them, we can assume that this is due to the dynamics of some internal, apparently deep energies, but it is difficult to say whether this reflects something important or is only "internal noise".

Not all dynamics dictate a person's behavior. While classical psychoanalysis describes cases where a person’s behavior was rigidly controlled by internal dynamics, was a necessary consequence of internal impulses and states, in Jungianism and the humanistic approach it often turns out that despite the influence of deep dynamics, a person’s external behavior can fully meet the circumstances, be socially adequate and within reasonable limits.

Some internal dynamics leave room for the person or his environment to carry out some activity (soft dynamics), others essentially dictate how the person will behave (hard dynamics).

Classical psychoanalysis describes cases when a person's behavior was controlled by rigid dynamics, was the result of internal impulses and states.

In other approaches, the external, social behavior of a person fully corresponded to external circumstances, was adequate and within the framework, but internal dynamics were of interest as an expression of what is happening in the inner world, the world of feelings and relationships. This is Jungianism and the humanistic approach.

Why do psychologists and clients of psychologists have an interest in the dynamics of the internal energies of a person? - Oddly enough, this is not an easy question. Knowledge of laws in science makes it possible (at least theoretically) to predict the course of the processes under study, but in psychological work this is practically not in demand. Sigmund Freud and his followers believed that the client's understanding of his internal situation, his awareness of the internal conflict removes him, but this assumption was not confirmed: awareness may or may not affect what is happening inside us.

A client with Crohn's disease is scheduled for a barium enema. What should the plan of care include today to prepare for the test tomorrow

Answer:

Encourage plenty of fluids.

Explanation:

The nurse should encourage plenty of fluids because adequate fluid intake is necessary to avoid dehydration that may be caused by the bowel preparation and to prevent fecal impaction after the procedure. The client may be placed on a low-residue diet 1 to 2 days before the procedure to reduce the contents in the GI tract. Fiber intake is limited in a low-residue diet. Because dairy products leave a residue, they aren't allowed the evening before the test. Clear liquids only are allowed the evening before the test.

How many skin colors would there be if it was inherited in a simple recessive pattern rather than in a polygenetic fashion?.

Answers

Answer: At least 4.

How many skin colors would there be if it was inherited in a simple recessive pattern rather than in a polygenetic fashion? At least four.

Due to the fact that many distinct genes, each of which contributes in some way to the total phenotype, four skin colors are inherited in a simple recessive pattern.

What is polygenetic fashion?

There are several slightly varied variations of these qualities four or more just as many as there are right now. Three genotypes and two phenotypes are conceivable in simple recessive inheritance.

Human skin color is a polygenic trait controlled by multiple genes, where each gene's dominant allele only partially expresses the trait.

The full trait is only expressed when the dominant alleles of all the different genes are present, this type of inheritance is referred to as polygenic inheritance.

Therefore, four skin colors are inherited in a simple recessive pattern than in a polygenetic fashion.
