The RDAs for nutrients are set based on the dietary intakes of people who appear to be maintaining nutritional health. based on a person's height and weight. to cover the needs of 97% of the population. by the FDA for food labeling purposes.
Answer:
The correct answer is '' to cover the needs of 97% of the population.''
Explanation:
The Recommended Daily Allowances or RDA, by definition, correspond to the average amount of a nutrient that a healthy person must ingest daily, through diet, to maintain a correct state of health. These established values are an approximate guide to meet the needs (intake level of a sufficient nutrient) of almost all (97 to 98%) individuals in the healthy population, but may vary due to factors such as age, sex or level of activity. It must be taken into account that each nutrient has a series of functions in the body, hence the importance of knowing the approximate amount that we should consume each day and, therefore, of knowing the RDA.
How to calculate the heart rate from the electrocardiogram ?
Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
When the person is being fed through an intravenous central catheter, they are given _____________________ nutrition.
The _______ is the muscular wall that makes up the bulk of the heart. The _______ ventricle is the thicker and larger ventricle. The atrium and ventricle of each side are connected by a/an _______valve. A single cardiac cycle consists of the simultaneous contractions of both _______ followed by the simultaneous contractions of both _______. The heart supplies blood to itself via _______ arteries. Contraction of the ventricles (and relaxation of the atria) is called _______, whereas relaxation of the ventricles is called _______. The heart pumps blood to the lungs for oxygenation via the pulmonary _______.
Answer:
The correct answer is - myocardium, left, cuspid, atria, ventricles, coronary, diastole, systole, arteries.
Explanation:
The myocardium is a cardiac muscle that makes the wall of the heart chambers, the left ventricles are thicker than the right ventricles, the cuspid valves and connects the chambers of each side.
Cardiac cycles are diastolic and systolic cycles that are contractions of ventricle and atria in a simultaneous pattern of 0.08 seconds.
Answer:
1. myocardium
2. left
3. atrioventricular
4. atria, ventricles
5. coronary
6. systole, diastole
7. artery
8. Deoxygenated or bad blood mixed with waste gasses and chemicals is collected from throughout the body via veins and brought back to the heart. Then the heart pumps the impure/deoxygenated blood to the lungs for oxygenation via pulmonary arteries. Pure/oxygenated blood is delivered back to the heart via pulmonary veins. Then oxygenated blood is supplied throughout the body via arteries, including to the heart itself via coronary arteries.

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
a nurse is teaching a pt about fecal occult blood testing (FOBT) for the screening of colorectal cancer, what statement should the nurse include in the teaching
Answer:
you should avoid eating red meat prior to testing
Explanation:
A fecal occult blood testing (FOBT) is a cost-effective, non-invasive method for colon cancer screening, which can be used in asymptomatic patients. The FOBT test is used to identify hidden blood in stool samples, which may be indicative of colon cancer and the presence of polyps in the colon/rectum. It has been shown that screening by FOBT can significantly reduce mortality from colorectal cancer. Two days before the FOBT test, it is imperative to avoid red meats and other foods (e.g., beets, carrots, cauliflower, cucumbers, grapefruit, broccoli, cantaloupe, etc), which might lead to false alarms.

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.
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.

The correct answer is - Type 2 diabetes mellitus has major components: insulin resistance and impaired insulin secretion.
Explanation:
In type 2 diabetes there are two major components that play an important role to cause this that are Insulin resistance in which insulin could not bind with the specific receptors that result in less effective at stimulating glucose uptake.
The other major component is impaired insulin secretion in which an increased amount of insulin is required that there is not enough insulin to prevent the breakdown of fats and production of ketones.
A weight reducing diet required the daily intake of ‘liquid protein’[soup of hydrolyzed gelatin], water and an assortments of vitamins. All other food and drink were to be avoided. People on this diet typically lost 10 to 14kg in the first week. A number of persons on this diet died. What are some of the dangers inherent in the diet and how can they lead to death?
Answer: See explanation
Explanation:
From the information given, it should be noted that Gelatin has a nutritional distribution of amino acids that's unbalanced.
It should be noted that in a scenario whereby large amounts of gelatin are ingested into the body such that there is catabolizing of the excess amino acids, there will be an excess of the urwa cycle capacity which then brings about ammonia toxicity.
Furthermore, the dehydration which can be caused due to the excretion of large amount of urea can also lead to death.
