Exercise and eating a health variety of foods help develop physical health; taking a course in general nutrition helps develop intellectual health; buying locally produced food helps develop environmental health; being part of a faith-based organization helps develop spiritual health; and keeping a journal helps develop emotional health. The missing dimension in this example is development of social health; eating meals with friends throughout the week would add this dimension. Growing her own food would be another example of environmental health; keeping a food record would be another contributor to physical health; and meeting with a registered dietitian may contribute to physical, intellectual, and emotional health.

low blood sugar levels

high blood sugar levels

high blood pressure

extremely low blood pressure

ANS: D Poor eating habits affect emotional health. Missing meals may cause blood sugar levels to decrease, which can cause anxiety or confusion or make it difficult to control emotions. Late night binges on snack food are likely to result in excessive energy intake but would have a less direct effect on emotional health. Eating small meals throughout the day is likely to maintain more constant blood sugar levels, which would actually have a positive effect on emotional health.

Low intake of fruits and vegetables by African American children is likely to have an adverse effect on their health and so may be addressed when target goals are set. Vegetarian eating patterns, use of bottled water, and use of protein and vitamin supplements do not necessarily have an adverse effect on nutritional health and so are less likely to be addressed.

d .

being aware that Salmonella can be transmitted because of inadequate food preparation.

ANS: C Food labeling information is an example of community support because it is a regulatory measure that supports new health-promoting behaviors within a social context.

ANS: C Health promotion consists of strategies that are designed improve the health of individuals, families, groups, and communities, such as teaching a teenager how to choose healthier fast foods. Exercising regularly contributes to wellness, but it is not bringing about a change in health unless this is a change in behavior. Stocking a wider availability of fresh produce does not promote health, unless the supermarket uses specific strategies to encourage consumption.

monounsaturated fat.

saturated fat.

ANS: D Saturated fat intake is related to risk of heart disease and certain types of cancer. Monounsaturated fat intake has less effect on risk of these diseases. Dietary fiber intake should be increased to help reduce risk of cardiovascular disease and cancer. The effects of protein intake on risk of these diseases are much less significant.

b .

it focuses on ethnic and socioeconomic groups at greatest risk.

c .

it collects large volumes of survey data from all over the nation.

d .

survey methods and standards are consistent from year to year.

ANS: A Data from NHANES represent America overall because the survey populations are carefully selected to represent the total population. Their data therefore provide a better indication of the nations overall health than do large amounts of data from all over the country. It does not focus specifically on populations at high risk for disease. Standardization over time provides useful data on trends and changes but does not reveal the overall health of the nation.

Members of an ethnic minority population can be very helpful in identifying needs and effective teaching strategies for people in their community and in encouraging people in the community to accept advice from nurses or other health professionals. They do not necessarily need to adopt American eating patterns; often these are less healthful than their traditional eating patterns. Setting up feeding programs does not promote positive self-efficacy. Visual aids may be helpful, but their use is not necessarily the best educational strategy.

A client has heard that nutrients can be converted to other nutrients in the body. He takes high-dose vitamin C supplements because he believes this will supply his bodys need for other vitamins. What would you tell him? a .

He should switch to a multivitamin supplement instead of just vitamin C.

b .

Each vitamin has a specific function and needs to be supplied through a variety of foods.

c .

Vitamin C can provide only water-soluble vitamins, and he still needs to consume fat-soluble vitamins.

d .

Vitamin C supplements should be taken only when he has symptoms of a cold or influenza.

ANS: B Vitamins cannot be converted into other vitamins; each has a specific function, and the best way to consume adequate amounts of each vitamin is to eat a variety of foods. Vitamin C is water soluble, but it cannot be converted to other water-soluble vitamins. Vitamin C is needed by the body at all times, not just when someone is ill. A multivitamin supplement would provide a better range of vitamins than just vitamin C, but it is still better to consume vitamins from food, rather than from supplements.

inadequate income to purchase healthy foods.

insufficient time to plan and prepare healthful meals.

lack of knowledge about healthy eating.

ANS: C For busy professionals and families, the biggest barrier to healthy eating is usually hectic schedules and lack of time to plan and prepare healthy meals. Most mothers, especially those who work in a health care field, are concerned about their familys health. Many professional women have at least some understanding of healthy eating.

He has certain genetic taste markers that make him a super taster.

b .

He associates eating green vegetables with unpleasant childhood memories.

c .

He needs to train himself to enjoy the acquired taste of bitter vegetables.

d .

He is making an excuse to avoid making healthful changes in his eating habits.

ANS: A Some people have variations in genetic taste markers that make them super tasters. These people often experience the taste of certain vegetables as being bitter. Environmental factors such as childhood memories may also influence food choices but are not usually associated with tasting vegetables as bitter. Tastes can be acquired and sometimes people make excuses to avoid making changes, but these are less likely explanations for this particular problem DIF:Cognitive Level: ApplyingREFage 18 TOP: Nursing Process: Assessment MSC: Client Needs: Health promotion and maintenance 2.

d .

environmental effects of parental food choices and television watching.

ANS: D Because young children spend so much time with their families, their parents food choices have a major effect on their own future food choices. Preventing young children from eating while watching television will have only a short-term effect, and they are likely to imitate their father in eating high-fat, high-sugar snacks. The fathers food preferences are probably influenced by genetics and ethnicity, and it may be interesting to find out whether the childrens current weights are healthy for their heights (although their birth weight is probably not relevant), but this information has less immediate effect on the nutritional health of this family.

d .

inadequate intake of key vitamins, minerals, and phytochemicals.

ANS: C Most Americans have high intake of saturated fats, cholesterol, sodium, and sugars, which is associated with increased prevalence of chronic disease. Many people have inadequate intake of micronutrients, but this has a lesser overall effect than excessive intakes of fats, sodium, and sugars.

health of Americans. Preservatives per se have not been associated with health status (although foods that contain preservatives may be more highly processed and may have higher levels of fat, sugar, and sodium and lower levels of nutrients than do foods without preservatives).

ANS: D Fruits & VeggiesMore Matters is designed to increase intake of fruits and vegetables. Fruits and vegetables are naturally low in fat; they would replace higher fat foods in the diet and thus would indirectly decrease dietary fat intake.

ANS: D In the Exchange Lists for Meal Planning, foods are grouped according to their kilocalorie, carbohydrate, protein, and fat content, and serving sizes that contain specific amounts of each of these are listed. Therefore, this guide can help clients monitor their intake. The National Fruit and Vegetable Program simply encourages increased intake of fruits and vegetables.

ANS: B Fruits and vegetables replace high-fat foods in the diet because they are high in fiber and water; they cause satiety so that clients have less desire for high-fat foods. Fruits and vegetables are not, and do not contain, natural appetite suppressants and do not hinder absorption of fat from foods.

Larger portion sizes often contribute to excessive caloric intake.

b .

Eating away from home means less social interaction.

c .

Eating out tends to decrease the variety of foods eaten.

d .

Restaurant meals are associated with more sedentary lifestyles.

ANS: A Restaurants and fast food outlets often serve large portions that increase caloric intake. Eating away from home does not necessarily decrease social interaction, inasmuch as families or friends may eat away from home in groups. Eating out does not necessarily decrease the variety of foods eaten, depending on individual food choices. Eating out has not been related to physical activity levels.

amount of nutrients per serving.

ANS: A The Percent Daily Value shows how a food fits into the overall daily diet and would therefore show whether it makes a high or low contribution to nutrient intake. Health claims may indicate that a food has high or low amounts of specific nutrient related to that particular health claim, but they would not indicate overall nutrient content of the food. The organic seal, if present, indicates the farming methods used to grow the food but does not give any information about nutrient content. The amount of nutrients per serving is listed for only some nutrients; the listing would not give any information about vitamins and minerals in the food because these are listed only as Percent Daily Values. Chapter 3. Digestion, Absorption, and Metabolism MULTIPLE CHOICE 1. Peristalsis is necessary to make it possible for people to a.

chew

food.

ANS: C Peristalsis makes swallowing possible as involuntary movements of circular and longitudinal muscles move food along the esophagus from the mouth to the stomach. Chewing is accomplished by jaw muscles and is not related to peristalsis. Peristalsis helps move food along the gastrointestinal tract to the places where digestion of each nutrient takes place, but it does not make digestion itself possible. Smell and taste are not related to peristalsis. DIF:Cognitive Level: ApplyingREFage 42 TOP: Nursing Process: Assessment MSC: Client Needs: Physiological integrity 2.

b .

churning and mixing of food in the stomach.

c .

action of bile breaking fats into smaller droplets.

d .

effects of secretin in stimulating the pancreas to release bicarbonate.

ANS: B Churning and mixing of food in the stomach is an example of mechanical digestion because it causes physical breakdown of the food. Salivary amylase is an enzyme that causes chemical breakdown of food; bile causes emulsification of fats. Secretin is a hormone that stimulates release of bicarbonate from the pancreas; this buffers stomach acid so that intestinal enzymes can work.

ANS: C Heartburn is caused by reflux of acidic stomach contents into the esophagus when the sphincter muscle between these two parts of the digestive tract does not operate properly. Constipation is usually caused by slow peristalsis, often in relation to inadequate intake of dietary fiber and fluid. Gallbladder disease is unrelated to gastrointestinal sphincters. Peptic ulcer is usually caused by Helicobacter pylori infection.

ANS: B Hormones act as messengers between organs to cause release of needed secretions. Some, but not all, hormones are proteins. Enzymes work locally on specific classes of nutrients to change them from one form to a simpler form. Nerve impulses send messages in the body but via electrical impulses rather than via chemicals.
