ATI Nutrition Practice A

1. The nurse understands that malnutrition is a prevalent issue among hospitalized individuals. What is it commonly associated with?

A. Decreased health care expenses
B. Elevated blood pressure
C. Decreased mortality rates
D. A compromised immune system

Correct answer: D

Rationale: Malnutrition is often associated with a weakened immune system. This is because when the body is not sufficiently nourished, it lacks the necessary nutrients to maintain a well-functioning immune system, making patients more vulnerable to infections and other health complications. This can potentially increase mortality rates and prolong hospital stays, contrary to choice C. Choices A and B are incorrect as malnutrition does not lead to decreased health care costs or high blood pressure. In fact, it may increase health care costs due to the potential for increased complications and extended hospital stays.

2. Which factor has been shown to increase the risk of development of atherosclerosis?

A. Menopause
B. Age older than 35
C. Increased levels of arachidonic acid
D. Elevated HDL cholesterol

Correct answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

3. Stimulates secretion of bicarbonate ions and digestive enzymes from the pancreas to the small intestine:

A. pepsin
B. salivary amylase
C. CCK
D. secretin

Correct answer: D

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.

4. What is the primary purpose of dietary fiber in the diet?

A. Improving digestion
B. Providing energy
C. Aiding in the absorption of vitamins
D. Reducing cholesterol

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

5. Does alcohol contain energy and is therefore a nutrient?

A. True
B. False
C.
D.

Correct answer: B

Rationale: Alcohol does contain energy and provides calories, but it is not considered a nutrient. Nutrients are substances that contribute to essential bodily functions. While alcohol may have energy, it does not provide essential vitamins, minerals, or other nutrients necessary for the body's health. Additionally, excessive alcohol consumption can have harmful effects on the body, further supporting why alcohol is not classified as a nutrient.
