Endocardial cushion defect

A developing embryo has a complete endocardial cushion defect. The fetus develops to full-term and is born at 39 weeks gestation. 1) Describe which septum is missing in this newborn (2 marks); 2) Compare and contrast the blood flow in the developing fetus (1 mark), to that in the newborn, including oxygenation and shunting of blood (1 mark); 3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark).

Hint: Think about which side of the heart will end up with more blood (i.e. blood volume) as the heart beats, and identify how this increased blood volume will impact the heart tissue growth (i.e. hypertrophy, etc.) Keywords: Atria, Ventricle, shunt, hypertrophy Use dot points to answer this question *Use dot points 1)

3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark).

The basis of an evidence-based change

/0 Comments/in /by

Reflect on your current healthcare organization and think about potential opportunities for evidence-based change. The use of negative or positive pressure in the OR for covid 19 positive patients.

Identify a clinical issue of interest that can form the basis of an evidence-based change. Develop a PICOT question to address this issue.
Using the keywords from the PICOT question, search at least four different databases in the Walden Library to identify at least four relevant peer-reviewed articles at the systematic-reviews level. Briefly describe your healthcare organization, including its culture and readiness for change. (You may opt to keep various elements of this anonymous, such as your company name.)-Ascension Healthcare.
Describe the current problem or opportunity for change. Include in this description the circumstances surrounding the need for change, the scope of the issue, the stakeholders involved, and the risks associated with change implementation in general.
Propose an evidence-based idea for a change in practice using an evidence-based practice approach to decision-making. Note: You may find further research needs to be conducted if sufficient evidence is not discovered.
Be sure to include a description of the PICOT question that you developed for your search, and which databases you consulted.
Describe your plan for knowledge transfer of this change, including knowledge creation, dissemination, and organizational adoption and implementation.
Describe the measurable outcomes that you hope to achieve with the implementation of this evidence-based change.

Suggestive source of online interactive modules

/0 Comments/in /by

Locate and participate in one online interactive instructional module.  If the interactive instructional module you chose to analyze has multiple modules, you are only required to review one of the modules. Your review should be 450 – 600 words. The following website is a suggestive source of online interactive modules. However, you are allowed to explore other websites: https://intensiveintervention.org/training/online-learning-modules

Section I: Describe the content, purpose, target audience(s), and sponsors of the module(s);
Section II: Critique the strength and weaknesses of the module for your topic and the targeted audience.
Section III: Evaluate the intended effectiveness of the module in changing the mindset, behavior, education level, etc. of the targeted audience.
Print out and attach the first page of the module so that the website address shows on the printout.

The leading cause of morbidity and mortality

/0 Comments/in /by

The leading cause of morbidity and mortality in the US is cardiovascular disease. It is commonly a result of years of chronic inflammatory changes to the lining of the blood vessel (endothelium) caused by excessive calories (free radical oxygens from burning fats) and lack of exercise (insulin resistance) and/or smoking. Metabolic syndrome is a constellation of excessive central fat (waist>hip ratio) high blood pressure + elevated LDL with low HDL + insulin resistance (pre-diabetes) or Type 2 diabetes. We use medications in combinations to reduce LDL cholesterol, reduce triglycerides, reduce weight, lower blood pressure, improve insulin resistance, and lower blood sugar levels.

Choose one drug from each of these categories and discuss how they work together better than they would work separately. You will need to demonstrate an understanding of how they interact on the body (pharmacodynamics).

Limit your information to one page and cite your references.

Key achievement of the sensorimotor stage of development

/0 Comments/in /by

Piaget believed that object permanence is the key achievement of the sensorimotor stage of development. In Piaget’s view, this occurs at 2 years of age for most individuals. For an example of this phenomenon in action, see the following video: http://www.youtube.com/watch?v=nwXd7WyWNHY&feature=related (you may need to paste the link into your browser window)

Some developmental psychologists, while acknowledging Piaget’s vast contributions to the field, nonetheless question his views regarding object permanence. In your own view or experience, do you feel that object permanence (i.e., understanding that something persists even when out of view) develops as noted by Piaget, or is it possible that individuals have an understanding of object permanence even earlier?

Provide a full, three-paragraph post referencing a journal article in APA style (listed at the bottom of your discussion). You must also provide a full paragraph (at least three sentences) response to at least two other discussion posts.

Dietary management and physical activity

Mrs. Melisa Carfi, a 65-year-old female patient with Type 2 diabetes mellitus, was admitted to your healthcare facility with non-healing foot ulceration. Prior to admission, Melisa’s diabetes was managed with metformin. Upon admission, subcutaneous insulin with a diabetic diet was initiated along with oral anti-diabetic agents to achieve optimal blood glucose control.

2. Provide a list of four (4) specific questions you would ask Melisa in order to seek information to confirm her understanding of the condition and its impact.

What specific information will you give to Melisa if you are to provide health education on dietary management and physical activity with the goal of losing weight?

The Nernst equation

/0 Comments/in /by

Using the Nernst equation, calculate the equilibrium potential for the sodium ion if the concentration of sodium outside is 130 mM, and the concentration of sodium in the cytoplasm is 12 mM. Show your work.”

I do not necessarily require the answer (though it would be helpful to know if I do it right), but step by step on how to set this up would be helpful. Would the equation be the same in the situation of potassium (given different numbers of course). Or would something change for that?

Thank you.
