Answer:
Pacemaker cells generate spontaneous action potentials that are also termed "slow response" action potentials because of their slower rate of depolarization. ... Another difference between cardiac and nerve and muscle action potentials is the role of calcium ions in depolarization.

Cholesterol is necessary for the production of many other compounds in the body but can become harmful when blood levels exceed 135 mg/dl. exceed the body's ability to use it. can only be controlled through medications. a and b.
Answer:
The correct answer is a and b( exceed 135 mg/dl and can only be controlled through medications.)
Explanation:
Cholesterol is a natural fatty substance that is present in the body and is necessary for the proper functioning of the cells of the human body. It is considered to be at the high limit when the whole blood level exceeds 130 milligrams per deciliter of blood (mg / dl). When this happens, fats tend to build up inside the arteries, impeding blood flow and can lead to serious heart disease and stroke. A doctor usually prescribes drugs to lower high cholesterol (they usually recommend statins), it is because the person is in the intermediate risk limit and has factors that increase the risk of heart disease or stroke, causing long-term arteries become clogged and diseases such as atherosclerosis or heart attack appear.
Why have risky behaviors for zoonotic diseases continued even though we know that some of these diseases can infect humans?
Answer: Zoonotic diseases are those diseases that are transferred from animals to humans.
Explanation:
In zoonotic diseases animals are the vectors for the transfer of disease from humans to animals. The organisms that are transferred through zoonotic diseases are bacteria, viruses, fungi, and parasites. Mostly the disease causing organisms are parasites. For example rabies, Lyme disease, plague, salmonellosis, west nile virus, and others. These diseases develop risky human behavior. For example humans affected by rabies show phobia from water. Some humans also develop biting tendency.

Solution:
The child is experiencing infective endocardits.
Treatment with aqueous penicillin or ceftriaxone is more effective foe most infections caused by streptococci. The combination of penicillin or ampicillin with gentamicin is appropriate for endocarditis caused by enterococci that are not highly resistant to penicillin intial empiric therapy in patients with suspected endocrditis should include plus in an aminoglycoside
The valve replacement is considered in selected patients with infectious endocarditis
The common congental defects that cause hearts murmurs include holes in the heart or cardiac shunts which is known as septal defects.
The disease that should be considered is infective endocarditis whose treatment can be based on antibiotics.
Infective endocarditis is a type of infection in the internal heart tissue called the endocardium.This disease (infective endocarditis) may be caused by different harmful microorganisms (.e.g, bacteria, fungi, etc), which in this case could have entered into the body through the skinned knee.Infective endocarditis can be treated by using proper antibiotics to kill harmful microorganisms.In conclusion, the disease that should be considered is infective endocarditis whose treatment can be based on antibiotics.

Calculate the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m2. The adult dose of the drug is 500 mg. Record your answer using a whole number. _____mg
Answer:
87 mg
Explanation:
To find the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m², we use the formula given below
Child dose = child surface area/1.73 × adult dose
Given that the child surface area = 0.30 m² and the adult dose = 500 mg,
Child dose = child surface area/1.73 × adult dose
Substituting the values of the variables into the equation, we have
Child dose = child surface area/1.73 × adult dose
Child dose = 0.30 m²/1.73 × 500 mg
Child dose = 0.1734 × 500 mg
Child dose = 86.71 mg
Child dose = 87 mg to the nearest whole number

Answer:
Explanation:
A C-section scheduled for Meredith is best for her. A dilation of 4cm can't proceed with normal labor. Being in labor for 12 hours is dangerous for the mother and fetus. Even if the fetus demonstrates no stress yet, it is safer to have a C-section for Meridith to keep the mother and fetus in good status.
If a person’s diet includes a lot of processed foods and not a lot of fresh fruits or vegetables, failing to meet recommended intakes of ______ is likely.
Answer:
potassium
Explanation:
Got it right on the test.
If a person's diet consists primarily of processed foods and not a lot of fresh fruit and vegetables, he or she is more likely to fall short of meeting recommended potassium intakes, as fresh foods are high in potassium.
What are the roles of the ions in the body?The ions' role is important for the body as they maintain equilibrium in the body and there are many ions such as sodium, potassium, calcium, chloride, etc., and if an ionic imbalance is attained in the body, many diseases are seen and the body's homeostasis is affected. In general, eating green vegetables and natural foods balances the ions, whereas eating processed foods creates an imbalance due to the high sodium content of preservative products.
Hence, if a person's diet consists primarily of processed foods and not a lot of fresh fruit and vegetables, he or she is more likely to fall short of meeting recommended potassium intakes, as fresh foods are high in potassium.

The diversity of both students and faculty poses important considerations for teaching and learning. Reflect on the characteristic differences in gender, race, and culture, as well as the differences among the diverse generations in today’s nursing education classroom. When considering your personal philosophy of teaching, discuss how you might use these characteristic differences and diverse backgrounds and experiences of today’s nursing students as a teaching tool to connect students to nursing content and increase their understanding. In other words, how might you incorporate the background and experiences of your students into your teaching methods to enhance the ability of all students in your classroom to think critically and problem solve patient-care issues?
Answer:
As of 2016, the ethnic breakdown of the United States was 61.3 percent white (non-Hispanic/Latino), 17.8 percent Hispanic/Latinx, 13.3 percent black/African-American, 5.7 percent Asian, 1.3 percent Native American/Alaskan Native, and 2.6 percent reporting two or more races. In the same year, about 70 percent of all nurses were white — significantly more than the general population. African-American and Latinx populations in particular were underrepresented as a proportion of the nursing profession. The contrast was even more stark when considering nursing educators. In 19 states, the percentage of minority nursing students was at least double that of minority faculty.
This disparity can be a barrier to effective nursing education. Studies by respected organizations, such as the Sullivan Commission on Diversity in the Healthcare Workforce, show that educational outcomes improve when nurse educators reflect, value, and celebrate the diverse attributes of the student groups they teach. On the other hand, educational outcomes suffer when nurse educators fail to do these things. Diversity within an organization’s teaching staff is therefore a helpful tool for attracting, retaining, and training enthusiastic and skilled nursing students.
