Question 1

Which of the following statements is true?

Accepted Answer

The FDA can recall a dietary supplement when there is evidence that it is harmful. However, the FDA does not regulate the labeling of dietary supplements, and manufacturers are not required to inform the FTC about negative health reports. Medicinal herbs also do not undergo testing for safety and effectiveness by the FDA before they can be marketed.

Question 2

Which of the following statements is true?

Accepted Answer

Consumers can report any negative health reports or side effects they experience after using dietary supplements to the FDA through MedWatch, a program that collects and analyzes such reports. Reporting these negative health reports helps the FDA identify potential safety issues with dietary supplements.

The other statements are false. 
B) Dietary supplements are meant to be taken orally, and injecting or using them topically can be dangerous.
C) Dietary supplements can be recalled if they contain harmful or prohibited substances, but kava, lysine, and glucosamine are not banned or prohibited substances.
D) Medicinal herbs are not required to be tested by the FDA for safety or effectiveness before being marketed in the United States.

Question 3

After examining a patient and reviewing the results of his blood tests,a physician tells the patient that his mild depressive symptoms are not the result of a serious health problem.The physician suggests that the patient should try regular exercise and take the dietary supplement St.John's wort for 3 months.After this period,the physician will prescribe antidepressant medication,if the patient does not feel emotionally better.This advice is ________.

Accepted Answer

The physician's approach of combining conventional medical treatments with alternative therapies (exercise and St. John's wort) before prescribing medication is indicative of integrative medicine, which aims to treat the whole person, not just the symptoms.

Question 4

A medical researcher reads an article in "Today's Health-Conscious Woman" magazine about the benefits of using the phytochemical capsaicin to treat knee pain.She asks 10 people with arthritic knees to rub a cream that contains the phytochemical on their knee joints for two weeks.At the end of the two weeks,the researcher asks the subjects whether their knee pain improved,stayed about the same,or worsened during the treatment period.After collecting responses from the people,the researcher reports the results of her study during a popular TV show that is hosted by a doctor.Based on this information,which of the following statements is true?

Accepted Answer

The researcher did not use a control group in her study, which is a standard scientific design for research involving human subjects. Without a control group, it is difficult to determine whether any improvement in knee pain is actually due to the capsaicin cream or simply the placebo effect. This study is also lacking peer-review and is not a part of any scientific literature.

Question 5

Which of the following practices is an example of integrative health care?

Accepted Answer

Integrative health care combines traditional medical treatments with alternative therapies, such as massage therapy, to address a patient's physical, emotional, and spiritual needs. Option D is an example of integrative health care because it combines the use of cortisone injections (a traditional medical treatment) with massage therapy (an alternative therapy) to treat the patient's back pain. Options A, B, and C do not involve the use of alternative therapies to complement traditional medical treatments, so they are not examples of integrative health care.

Question 6

A group of scientists suspects that certain dietary practices are partially responsible for different rates of hypertension among adults of different ethnic/racial groups.To test their hypothesis,the researchers examine data concerning the different population groups' hypertension rates and their past dietary practices.This research is a(n)_____ study.

Accepted Answer

The research is retrospective because it looks back at past dietary practices to examine their relationship with current rates of hypertension among different ethnic/racial groups.

Question 7

Which of the following statements is true?

Accepted Answer

Dietary supplements can interact negatively with other substances a person takes. It is important to consult with a healthcare provider before taking any dietary supplement, especially if a person is taking medication or has a medical condition. Options A, C, and D are not true statements. Physicians and registered dietitian nutritionists may recommend dietary supplements for their patients if they determine they are necessary, the legal definition of a dietary supplement is broader than just something that influences metabolism, and people should report side effects to the FDA, not the GAO.

Question 8

A scientist discovers a chemical in certain rocks that kills bacteria when it is mixed with sterile water in a test tube.She cannot market extracts that contain this chemical as a dietary supplement,because it ________.

Accepted Answer

The chemical does not contain dietary ingredients, meaning it is not a substance intended for ingestion as a supplement.

Question 9

Which of the following statements is true?

Accepted Answer

Disclaimers are typically used by manufacturers to protect themselves from legal action and can indicate that the product may not meet the expectations of the consumer or the claims made by the manufacturer. The other statements are false: not all individuals with a nutrition degree can refer to themselves as an RDN (they must pass a certification exam) and scientific evidence does not support the effectiveness of most alternative health care practices. Additionally, promoting drinking vinegar as a cure for lung cancer would be considered alternative medicine, not conventional medicine.

Question 10

Which of the following statements is true?

Accepted Answer

It is widely recognized that scientists' professional affiliations and sources of financial support can influence their research findings. This can create conflicts of interest and potentially bias their research results.

Question 11

Which of the following statements is true?

Accepted Answer

It is common for different studies to produce varying findings, especially in the case of studies involving human subjects. This is due to various factors such as differences in study design, sample size, and statistical methods.

Question 12

_____ can be classified as a dietary supplement.

Accepted Answer

Ginkgo biloba is a common dietary supplement that is believed to improve cognitive function and memory. Chewing tobacco and orange drink are not dietary supplements, while cherry jelly may or may not contain beneficial ingredients but is not commonly used as a supplement.

Question 13

Which of the following statements is true?

Accepted Answer

It is important for people to determine whether a dietary supplement is necessary and safe before taking it, as not all supplements may be appropriate for every individual. It is recommended to consult with a healthcare provider before starting any new supplement regimen. The other statements are not entirely accurate. The FDA's definition of a dietary supplement includes a wide range of products, including synthetic substances, and not all supplements are necessarily natural or beneficial for health. Physicians and registered dietitians may recommend certain supplements depending on individual needs and health conditions. People who experience side effects from supplements can report them to the FDA, not the GAO.

Question 14

Which of the following statements is true?

Accepted Answer

The RDN credential (Registered Dietitian Nutritionist) is legally protected and requires specific education and training to obtain. Options A, B, and C are all false statements. Scientific evidence does not support most forms of alternative health care, disclaimers are often used to protect manufacturers from legal action and a person with a PhD promoting vinegar as a cure for lung cancer is not practicing conventional medicine.

Question 15

After examining a patient,a health care practitioner tells the patient that her mild back pain is caused by poor flow of energy from her mind to her back.The practitioner treats the patient with acupuncture,ginseng,and massage therapy.Based on this information,the practitioner's treatments indicate that he relies on ________.

Accepted Answer

The practitioner's use of acupuncture, ginseng, and massage therapy suggests that he relies on alternative health care, which includes non-mainstream approaches such as traditional Chinese medicine and herbal remedies. The practitioner's explanation of the cause of the patient's back pain also reflects a belief in energy flow and holistic healing, which are common tenets of alternative health care.

Question 16

_____ can be classified as a dietary supplement.

Accepted Answer

Bitter orange is often used in dietary supplements for weight loss and appetite suppression.

Question 17

Which of the following statements is true?

Accepted Answer

Scientific studies can have different methods, sample sizes, and other variables that can influence the results. Therefore, it is not uncommon for studies investigating the same question to have different findings. Choices A, B, and D are all false. Researchers strive to minimize bias in their analyses, dietary recommendations are based on the consensus of multiple teams of nutrition researchers, and nutrition science is constantly evolving, with new discoveries and updates on nutrient functions.

Question 18

Which of the following statements is true?

Accepted Answer

A PhD promoting a cure for lung cancer that is not supported by scientific evidence is engaging in quackery. The other statements are not true. The effectiveness of alternative health care is not universally supported by scientific evidence. The Registered Dietitian Nutritionist (RDN) credential is a specific certification that requires additional education and training beyond a college nutrition degree. Disclaimers often serve to limit a manufacturer's liability by informing consumers of potential risks or limitations of a product.

Question 19

Which of the following practices is an example of integrative health care?

Accepted Answer

Integrative health care involves incorporating both conventional medicine and complementary and alternative therapies. In this case, psychological counseling is a conventional therapy, while taking St. John's wort is a complementary therapy. Combining the two is an example of integrative health care. Choices A, B, and C involve only conventional medicine.

Question 20

A group of registered dietitian nutritionists is planning to conduct a scientific study to investigate the effects of eating honey on school-age children's behavior.At first,the researchers will ________.

Accepted Answer

Before gathering data or identifying relationships between variables, the researchers would first make observations to determine how the children behave without honey consumption. This will serve as a baseline for comparison with the children's behavior after consuming honey.
