OSTEOPOROSIS:
Almost everyone knows, thanks to everything from newspaper articles to endless television commercials, that bone density is a major health concern for women. Osteoporosis has become a familiar term, and more and more women are booking bone density tests to make sure all is well underneath the skin. In all the hype, however, there are certain people who are being overlooked: men. It appears that older men need routine checks for bone thinning as well.
A new computerized tool sponsored by the World Health Organization is being used to identify the people most at risk for experiencing a broken bone. One of its findings is that men older than 70 years of age should have a bone mineral density x-ray test on a regular basis. This tool, called FRAX, calculates the risk of a person experiencing a hip, wrist, shoulder, or spine fracture within the next decade. Those tested were age 40 or older and either had osteoporosis or low bone mass.
FRAX takes many different elements into consideration when figuring a person's risk level. It factors in diet, exercise, and exposure to sunlight, for example. It also looks at where people live, what genetic factors might be involved, as well as lifestyle factors such as smoking, heavy alcohol consumption, and the use of steroids. The National Osteoporosis Foundation has used the FRAX predictions to create updated guidelines. Their new recommendations not only include bone density tests for men but also a stronger emphasis on the importance of weight-bearing and muscle-strengthening exercises and an increased amount of vitamin D supplementation.

Question 1 of 5

What is the meaning of the word 'booking' as used in the first paragraph?

A. Scheduling B. Contracting C. Traveling D. Charging

Correct Answer: A

Rationale: In this context, 'booking' refers to scheduling appointments for bone density tests. The correct choice is 'A: Scheduling' because in the given text, women are booking bone density tests to ensure their bone health. 'Contracting' (
Choice
B) is incorrect as it does not fit the context of making appointments. 'Traveling' (
Choice
C) and 'Charging' (
Choice
D) are also irrelevant to the context of scheduling appointments for medical tests.

PHOTOTHERAPY:
Phototherapy, commonly referred to as light therapy, has been an established form of medicine for more than a century. In recent years it has become closely associated with seasonal affective disorder, of which it is an effective and well-known treatment, but it is also used to treat a broad range of medical issues including acne, psoriasis, and eczema.
The most common form of light therapy involves a patient sitting in front of a medically designed light box for a prescribed amount of time every morning. The light is positioned at an exact distance from the patient's eyes so that it strikes both the skin and the retina. The light box mimics the effects of natural sunlight, but the UV rays are filtered to ensure there is no damage to the patient's skin or eyes. Phototherapy is thought to be a safe method of reducing the amount of bacteria on the skin, reducing inflammatory responses, and affecting the chemicals in the brain associated with mood.
One of the most recent technologies to be associated with phototherapy is the phototherapy blanket. In the late 1960s it was discovered that phototherapy can be used to treat jaundice in newborn babies. Neonatal jaundice, a yellowing of the skin in newborn infants due to excess bilirubin levels in the blood, is usually harmless but can cause brain damage if left untreated. Newborns are given a phototherapy blanket, a small pad with flexible LED light panels sewn into the fabric, to sleep with until their livers are able to process the excess bilirubin.
The many benefits of phototherapy make it a valuable resource for addressing a variety of ailments. Emerging innovations in LED and photo technologies ensure that many more practical applications will be developed for this particular form of treatment in the years to come.

Question 2 of 5

Which of the following statements is a fact?

A. Nurses should watch for jaundice in newborns. B. Untreated jaundice may cause brain damage. C. Phototherapy blankets are a valuable invention. D. Avoid neonatal units that lack phototherapy.

Correct Answer: B

Rationale: The correct answer is B: 'Untreated jaundice may cause brain damage.' This statement is a fact supported by the passage. Neonatal jaundice, if left untreated, can lead to brain damage due to excess bilirubin levels in the blood.
Choice A is not a fact but a general guideline for nurses.
Choice C is an opinion as it describes phototherapy blankets as valuable without citing a specific fact.
Choice D is not a fact but a recommendation, advising to avoid neonatal units lacking phototherapy.

VEGETERIAN DIET:
By studying the role diet might have in the prevention of cancer, recent studies have also noted that a vegetarian, or meatless, diet can help improve a person's overall health. A true vegetarian diet consists of a variety of grains, fruits, vegetables, nuts, and pulses—edible seeds from legumes such as peas, beans, and lentils. A modified vegetarian diet, known as lacto-ovo vegetarian, may include dairy products and eggs. A vegan diet excludes any food with animal origins, including butter, eggs, and honey.
When properly planned, a true vegetarian diet can provide a person with all essential nutrients, protein, and carbohydrates. In one study, researchers at Oxford University noted that overall, a vegetarian diet is lower in saturated fats and higher in fiber than other diets. The study noted that people who followed a vegetarian diet were generally found to have lower cholesterol and lower BMI (a measure of body fat based on a person's weight and height) and to be at a lower risk for certain types of heart disease. From the evidence presented, researchers suggested that the adoption of a vegetarian diet could prevent more than 30,000 deaths a year that are attributed to heart disease.
Other available information indicates that vegetarians live, on average, seven years longer than meat eaters do. Throughout the world, breast, colon, and prostate cancers are more common among people who have a high-fat, high-meat, low-fiber diet. Former Surgeon General C. Everett Coop has said that diet is a factor in 70 percent of all people who die from disease in the United States. On the whole, vegetarians are less likely to be afflicted with chronic diseases than those who make meat a centerpiece of their diet.

Question 3 of 5

What is the author's attitude toward vegetarianism?

A. Scoffing B. Positive C. Cautious D. Uninterested

Correct Answer: B

Rationale: The author presents a positive view of vegetarianism, citing benefits and supporting evidence.

EXERCISE:
It sounds contradictory, but here is some new advice for people who are feeling unusually tired: get out and get some exercise. Studies have shown that regular, low-impact workouts such as short strolls or brief bike rides can help increase overall energy levels by 20 percent and decrease fatigue levels by 65 percent. In other words, if you are feeling tired, the best way to feel more energetic is to get some exercise.
This advice is based on a study done by the University of Georgia's Exercise Pathology Lab. Three dozen people who did not get any kind of regular exercise yet consistently felt exhausted were divided into three groups. One group did not exercise at all. A second group worked out intensively on an exercise bike three times a week. The third group also worked out but at a slower pace. Of the two groups that exercised, both reported a 20 percent increase in energy levels. However, the group that exercised at a more leisurely pace stated that they experienced far less fatigue than the high-intensity group.
This was not the first study to point out a link between regular exercise and energy levels. The same team that conducted it also published one several years ago that stated that low-impact exercise can also help reduce fatigue in patients with serious health conditions such as heart disease and cancer. Clearly, it is time to get off the couch and onto the track.

Question 4 of 5

Which statement could be inferred from the passage?

A. The Georgia lab had conducted a previous study on the connection between exercise and energy. B. Exercise regimes are not recommended for patients with serious health problems. C. An increase in energy levels does not always correspond directly to a reduction in fatigue. D. There were fewer than 10 participants in each group in the Georgia study.

Correct Answer: A

Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before.
Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions.
Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue.
Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.
