the nurse has provided teaching to a patient who has diverticular disease but is not expericing an acute episode at this time. which statement by the patient reflects an adequate understanding of the tr=eaching?

Answers

Answer: The options are missing from the question,the options are;

"I will eat a diet that is low in fiber"

"I will avoid eating nuts and seeds"

"I will decrease my intake of fats and red meats"

"I will continue to work out by lifting weights"

The correct answer to the question is C

"I WILL DECREASE MY INTAKE IF FATS AND RED MEATS"

Explanation: Diverticular disease is the disease of the intestine that is characterised by formation of pouches,pockets or sac like structures in the intestine causing pain and sometimes inflammation.these small pouches are known as diverticula.

Individuals are encouraged to take meals that are high in fiber,fibers from vegetables and fruits and also to reduce their intake of red meat and fats as well as maintain a high level of physical activity inorder to decrease their risk of having diverticular disease.

It is yet to be proven that seeds and nuts can prevent diverticular disease but one can take a high fiber content meals once he or she presents with diverticular disease.

In diverticular disease,the goal is to apply less pressure on the abdomen inorder to avoid pain, an attack on the intestine or bursting of the pouches.

A patient with diverticular disease therefore needs to do activities and that will put little or no pressure on the abdomen, activities like vomitting,bending, straining at stool,lifting heavy objects and wearing tight) restrictive clothing can cause intraabdominal pressure and thus precipitating an attack on the already diseased intestine.

Conduct online research to identify public resources that could be used to fight the epidemic at your school. Make a list of resources that could be used to limit the spread of the virus, identify the students who have already been infected, and get treatment for those who need it.

Answers

The correct answer to this open question is the following.

In many different pages can be searched to find information. But I think that the federal government page takes you to some interesting links regarding public schools and prevention measures. That is where I focused my research.

So I found general recommendations that seem understandable. For instance, the detection of the temperature at the main gates of the schools. If students are sick, they better stay at home. You have to avoid contact with people sick. When coughing or when sneezing, the main recommendation is to cover your mouth with both hands or a tissue. Wash your hands constantly if you were outside. Do not touch your face. Stay at home if you can. And instead of using masks, eat well, have nutritious foods, improve your immune system, and do not have fear due to misinformation.

If there are people infected, they have to go to hospitals to get a diagnosis and receive the best treatment. The use of homeopathic medicine is a great and valid alternative that is working very well in other countries.
