The American Dental Association is much more.
For starters, do you know that the ADA is the largest and oldest dental society in the world? Is true. The first ADA meeting was held on August 3, 1859, two years before the start of the Civil War and only 83 years after the signing of the Declaration of Independence. And since that day the ADA has expanded to include more than 156,000 dentists from all states and Puerto Rico, it has increased its reach to support knowledge not only for those who care for teeth, but also for patients and their families.
Personal oral health has changed dramatically since the ADA was founded, a time when most people lost all their teeth at age 40. Centuries ago, our country was plagued by bad teeth, in fact, our first president, George Washington, was famous for his dentures made of carved ivory. In the mid-19th century, dust and toothpaste (stored in a jar) were the standard tools used for cleaning teeth at home. Prepared by the dentists themselves, the tools used to be very neglected and easily contaminated.
Carla had leukemia as a child and had to undergo numerous bouts of chemotherapy. The chemotherapy always made her nauseous. As she underwent a year of treatment, the waiting room started to make her nauseous. The nausea from the chemotherapy is the:
a. conditioned response.
b. unconditioned stimulus.
c. neutral stimulus.
d. unconditioned response.
Answer:
Unconditioned response.
Explanation:
Classical conditioning may be defined as the learning procedure when the biological strong stimulus is combined with neutral stimulus elicit a strong response.
In case of Carla the nausea from the chemotherapy acts as unconditioned response. The nausea is unlearned response and occurs due to the regular chemotherapy. The chemotherapy acts as unconditioned stimulus that results in the nausea that acts as unconditioned response.
Thus, the correct answer is option (d).
Final answer:
The nausea Carla feels from the chemotherapy is an unconditioned response, which is a natural reaction to the unconditioned stimulus of chemotherapy drugs; the waiting room, by association, triggers a conditioned response of nausea.
Explanation:
In the scenario described, Carla developed a conditioned response to the waiting room due to her chemotherapy treatments. The nausea she felt as a direct result of the chemotherapy is the unconditioned response (UR). In classical conditioning, an unconditioned response is an innate response that occurs naturally in reaction to an unconditioned stimulus (US), which in this case would be the chemotherapy drugs that caused the initial nausea.
The waiting room became a conditioned stimulus (CS) after repeatedly being paired with the chemotherapy treatments. Consequently, Carla's nausea upon entering the waiting room, even without receiving chemotherapy, is a conditioned response (CR) due to the association she has formed between the two.

A 55-year-old male patient underwent a colostomy. Earlier he underwent coronary artery bypass graft (CABG) surgery. The nurse finds the patient depressed and weeping. The patient expresses that he is fed up with his poor health. He feels that he has become a burden on his family because he can't work now. The nurse concludes that the patient is experiencing role performance issues. Which statement is true about role performance?
a. It is an individual's holistic feeling of self-worth or emotional appraisal.
b. It is the way an individual perceives his or her ability to responsibly carry out significant roles.
c. It involves the ideas and views of an individual related to physical appearance, structure, and function.
d. It is a conflict experienced when an individual has to perform two or more mutually exclusive responsibilities.
Answer:
D
Explanation:
dont use answers that conflict other opinions, because it can cause a frayed answer
Role performance is how an individual perceives his or her ability to carry out significant roles, which is option b from the choices provided. Role conflict occurs when incompatible expectations from different roles arise, and can contribute to job burnout, characterized by emotional exhaustion and reduced personal accomplishment.
Explanation:In the context of a 55-year-old male patient who underwent a colostomy and had previous CABG surgery, the true statement about role performance is that it is the way an individual perceives his or her ability to responsibly carry out significant roles. This aligns with option b from the provided choices. Role performance is influenced by various factors including personality, interpersonal relations, physical constraints, and moral values. It determines how individuals behave and present themselves in different aspects of their lives, much like actors on a stage, which was articulated by sociologist Erving Goffman's theory of dramaturgy.
It is important to understand that role performance can lead to role conflict when the expectations from different roles become incompatible. As observed in the patient's situation, the depression and the sense of being a burden stem from the disruption of his usual role within his family and society due to his health issues. This has likely led to a conflict between his previous identity and his current capabilities.
Consequently, this environmental and self-perception shift may contribute to a sense of job burnout, where emotional exhaustion, cynicism, and reduced sense of personal accomplishment are pronounced, particularly so in individuals who cannot fulfill their professional roles due to health complications.

When comparing a well-designed muscular strength workout to a well-designed muscular endurance workout, what differences can you see?
Answer:
When comparing a weel-designed muscular strength workout to a well-designed muscular endurance workout, the difference between is muscular strength was assessed by the one-repetition maximum (1RM) ... well-designed MRT exercises seem to be effective for improving muscular fitness.
In strength training, muscular endurance refers to the number of repetitions of a single exercise you can do without needing to stop and rest. Examples include how many times you can do a full squat, a sit-up, or a bicep curl with a light-to-moderate weight before breaking form.
The specific type of muscular endurance used during cardiovascular fitness activities such as running, swimming, or cycling is usually called cardiovascular endurance or cardiorespiratory endurance and is different from the strength training definition. Endurance training for these types of physical activities builds the energy systems of the body, the muscle fibers, and capillaries that can sustain long periods of exercise, such as running a marathon or cycling a 100-miler.

Ethnic minorities tend to utilize mental health services less frequently than White, middle-class Americans.B. Ethnic minorities tend to utilize mental health services more frequently than White, middle-class Americans.C. Ethnic minorities tend to utilize mental health services to the same extent as White, middle-class Americans.D. Ethnically Asian minorities tend to utilize mental health services less frequently than ethnically Black minorities.
The correct answer is A: Ethnic minorities tend to utilize mental health services less frequently than White, middle-class Americans.
Explanation:
Studies have shown that the middle-class White Americans do seek out mental health services more than any Ethnic minorities. This tends to happen because of the language barrier, embarrassment, poverty, and no access to health insurance.
The people who do not seek mental health treatment suffer greatly because of the impact it has on their well being and the well being of their families. Many mental health issues are treatable with the correct diagnosis but so many things keep people away from seeking treatment.

A. Ethnic minorities tend to utilize mental health services less frequently than White, middle-class Americans. Research indicates that ethnic minorities, including African Americans, Latinos, and Asian Americans, utilize mental health services less frequently than white, middle-class Americans due to various barriers, access issues, and cultural factors.
Research shows that ethnic minorities tend to utilize mental health services less frequently than White, middle-class Americans. Barriers such as lack of insurance, transportation, and time, as well as issues of access and availability, contribute to this disparity. Despite differences in income levels and insurance, ethnic minorities are far less likely to seek out and utilize these services when compared. Even when access is largely equivalent, utilization differences persist. Furthermore, African Americans and Latinos are more likely than whites to exhibit signs of mental distress but may face barriers such as mistrust of the mental health system and experiences of racism. Asian Americans are notably less likely than both whites and other ethnic minorities to seek outpatient treatment, influenced by cultural stigma, language barriers, and difficulty finding culturally competent services.

Aerobic activities a. enable muscles to use less oxygen than normal b. do not require voluntary muscle c. force muscle cells to use more vitamins and minerals for energy d. involve sustained, rhythmic contractions of certain large skeletal muscles
Answer:
A. Enable muscles to use less oxygen than normalExplanation:
The correct answer to the question is that aerobic activities involve sustained, rhythmic contractions of certain large skeletal muscles. This is reflective of the nature of aerobic exercises like cycling and brisk walking that rely on slow-twitch muscle fibers and consume a lot of oxygen to increase cardiovascular endurance.
The question primarily concerns aerobic activities, which involve sustained, rhythmic contractions of certain large skeletal muscles during exercise. Aerobic exercises such as cycling and brisk walking use muscles below their maximum contraction strength but for extended periods, which leads to increased cardiovascular endurance. These activities utilize a high percentage of slow-twitch muscle fibers that require a large amount of oxygen.
Option 'd' is the correct answer to the question, as aerobic activities do indeed involve sustained, rhythmic contractions of certain large skeletal muscles. Options 'a', 'b', and 'c' do not accurately describe the nature of aerobic activities. Aerobic exercises do not enable muscles to use less oxygen than normal, do require voluntary muscle contractions, and while they may aid in the more efficient use of vitamins and minerals, it is not because they 'force' muscle cells to use them for energy but rather as a result of overall increased metabolism and improved body functions.
