1. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second is false.
D. The first statement is false; the second is true.

Correct answer: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

2. What describes a common physical change of aging that can affect an older adult's nutrition?

A. reduced salivary output
B. increased gastrointestinal motility
C. abnormal cortisol production
D. increase in number of taste buds

Correct answer: A

Rationale: Reduced salivary output is a common physical change in aging. This can affect an older adult's nutrition by impacting chewing, swallowing, and taste perception. The decrease in saliva production can make it harder to chew and swallow food effectively, affecting the overall eating experience. Additionally, saliva plays a role in taste perception, so a reduction in salivary output can lead to alterations in how food tastes, potentially impacting an individual's appetite and food choices. Increased gastrointestinal motility (choice B) is not typically associated with aging and would not directly affect nutrition. Abnormal cortisol production (choice C) is related to hormonal changes and is not a common physical change of aging that affects nutrition. An increase in the number of taste buds (choice D) is not a typical change associated with aging and would not have a significant impact on an older adult's nutrition.

3. Cancers that arise from epithelial tissues are known as:

A. Leukemias
B. Myelomas
C. Carcinomas
D. Sarcomas

Correct answer: C

Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.

4. A nurse is providing teaching to an obese client who has gestational diabetes and is at 25 weeks of gestation. Which of the following statements made by the client indicates a need for further teaching?

A. This does not mean that my baby will have this disease.
B. This means that I will have diabetes for the rest of my life.
C. If I feel dizzy, I should drink six ounces of a non-diet soda.
D. Being obese might be one reason why I developed diabetes.

Correct answer: B

Rationale: The statement 'This means that I will have diabetes for the rest of my life' indicates a need for further teaching. Gestational diabetes often resolves after pregnancy, although it does indicate a higher risk for developing type 2 diabetes in the future. The other choices are correct or provide appropriate information: A) Understanding that gestational diabetes does not mean the baby will have the disease is accurate. C) Advising to drink non-diet soda if feeling dizzy is incorrect and potentially harmful due to the sugar content. D) Recognizing that obesity can be a risk factor for developing diabetes is a valid statement.
