Answer:

The three principles of test construction include standardization, reliability, and validity. In order for a test to be useful, it must contain all three elements. Standardization refers to the meaningfulness of test scores among test takers. It also includes providing all test takers with the same instructions, questions, and time constraints. A standardized score tends to follow a bell curve of score distributions and determines where a test taker's performance is relative to other testers. Secondly, a test must also be reliable to be useful. Reliability means that the test produces consistent results. A reliable test will give the same or similar score when someone is tested with an alternate version or retested with the same test. This establishes test-retest reliability. In order to establish split-half reliability for a test, even and odd problems may be designed to measure similar aspects and are then scored separately. This allows us to see if the person is consistent in scores on each half of the test. Finally, a test must be valid and measure what it is designed to measure. It is possible to have a very reliable test that is not valid.

Explanation:

Responses may vary but should include some or all of the following information:

Reputable tests have three factors in common. They are all standardized, valid, and reliable. Standardized tests have scores that are compared to the results of other test takers. Valid tests cover the information that is being looked at. Reliable tests have results that remain consistent over multiple testings.

What are the benefits of including some types of fish and shellfish in one’s pregnancy diet, and why must other types of fish an

REY [17]

The benefits of including some types of fish and shellfish in one's pregnancy diet are the essential nutrients that you can get from these foods. Fish and shellfish contain omega-3 fatty acids and also can be a great source or protein, iron and zinc that will help in the fetus' development especially brain development. Such include tuna and salmon. Some types of seafoods should be avoided because of the high levels of mercury it contains. Such fishes include: swordfish, king mackerel, tilefish and shark. When too much mercury is accumulated in the body, this might interfere with the development of the fetus.

Pavlova-9 [17]

Answer:

A man with muscle "dysmorphobia" is most likely to feel that he is scrawny, despite the fact that he is not.

Explanation:

A man with muscle "dysmorphobia" is most likely to feel that he is scrawny, despite the fact that he is not. Dysmorphobia is a condition that makes a person feel there’s some kind of ugliness or defect in some part of their face or body when there actually isn’t. A person that suffers from this condition may get obsessed with it and that can affect their social life, their performance at school or work. Dysmorphobia differs from anorexia and bulimia in the sense that it is related to a specific part of the body or face, whereas anorexia and bulimia are both related to weight and the size and shape of the body. In this case, the man suffering from dysmorphobia believes his muscles are unattractively thin. His problem is specifically related to the shape and condition of his muscles, although there's nothing really wrong with them.

Which assertion best describes the current state of evidence-based practice (EBP) in nursing?

hichkok12 [17]

Answer:

C. EBP in nursing is waning in emphasis and was never fully implemented.

Explanation:

Evidence-based practice (EBP) is a method used in the areas of medicine and health with the aim of using scientific evidence and data to deliver the best high-quality care to patients.

Although this is a great method that has been proposed for over a decade now, it hasn't been fully implemented by nurses due to different reasons:

Time: In a research study, scientists determined that nurses, although completely agree with this method, state that they are unable to carry out this method mainly due to lack of time and heavy workload.
Lack of statistical knowledge: In the same study, nurses stated that they had difficulty understanding statistical data that were required to complete the method of EBP.
Inability to understand technicisms: They also had a difficult time while trying to understand jargon or medical technicisms as many scientists overuse technical words in research papers, creating a barrier for them to fully implement EBP.

Therefore, EBP in nursing hasn't been rejected but it has never been fully implemented.
