Hi Class,

Nursing research involves quantitative research designs which involve large specimens focusing on the quantity of responses hence; there are various types of quantitative research designs such as the experimental quantitative research which deals with how members are assigned groups in experiment. The design incorporates isolated groups, repeated measures, and matched pair designs. According to Schmidt and Brown (2017), the experimental design offers the best proof for asserting that a connection exists between a source and the effect through the involvement of pre-test and post-test terms. Thus, the design examines the variations between the treated and untreated components in a study.

The major advantage of experimental research design is its provision of researchers with a high extent of jurisdiction where one is able to isolate particular variables making it possible to establish if a prospective result is feasible. Moreover, each variable can be controlled on its own or in various combinations to study what prospective end results are available for a product or a hypothesis (Noh & Kim, 2019). Thus, this is a great advantage since it allows one to find accurate outcomes. However, the main disadvantage of the design is that outcomes are highly personal due to the likelihood of individual mistakes which occur as a result of the design’s requirement to control particular quantities of variable. Thus, any mistake whether extensive or random, can disclose information about other variables and that would tamper with the rationality of the investigation and the study being conducted.

Therefore, the experimental research design has got a number of uses and applications when it comes to solving clinical problems. In some cases, the design could be used in nursing practice to solve a clinical problem through the use of the irregular constructive pressure breathing which is a comparatively compound and costly gadget to convey bronchodilators to the lungs by practicing nurses.

2. This is the second discussion that I have to reply too.

Research design includes sample, data, collection, implementing a strategy, and data analysis. In order for the design to develop, it must state a purpose and have a plan presented that can answer the research question and test the hypothesis that is being stated (Schmidt & Brown, 2019). The quantitative type design that I chose was nonexperimental design. This type of design is used to describe a phenomenon in detail, explain the differences and what the variables have in common, and predict relationships (Schmidt & Brown, 2019). What the researchers do is that they observe and take down notes on the occurrence of variables and see if they can determine what they have in common and what they differ from.

Within the nonexperimental type of research, they can use what is called a cross-section design. This design is used to gather data from one group of individual at only one point in time (Schmidt & Brown, 2019). One major advantage when it comes to cross-sectional design is that they are relatively inexpensive and quick to conduct (Salkind, 2010). A major disadvantage would be that the study cannot provide a very rich picture of development (Salkind, 2010). They also do not provide a lot of information about the ways individuals change change over time (Salkind, 2010).  An example as to how this quantitative research design can be used in nursing practice to solve a clinical problem would be to observe the amount of urinary tract infections that occur in the intensive care unit.
