1. Each statement is true of water-soluble vitamins, except one. Which is it?

A. Act as coenzymes
B. Deficiencies develop rapidly
C. Daily intake is necessary
D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

2. Which type of medication is most likely to induce xerostomia?

A. Antibiotics
B. Diuretics
C. Local anesthetics
D. Anticholinergics

Correct answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.

3. A nurse is completing a nutritional assessment of an adult female client. Which of the following findings should indicate to the nurse that the client is at an increased risk of developing cancer?

A. Eats at least 5 servings of fruits and vegetables daily.
B. Eats 6 servings of whole grains daily.
C. Limits alcohol consumption to 2 drinks per day.
D. Limits red meat intake to 3oz per day.

Correct answer: C

Rationale: The correct answer is C because limiting alcohol consumption to 2 drinks per day is still above the recommended limit for reducing cancer risk. The recommended limit for women is 1 drink per day to lower the risk of developing cancer. Choices A, B, and D are not indicative of an increased risk of developing cancer as they all align with a healthy diet and lifestyle, which can actually help reduce the risk of cancer.

4. Which of the following are the primary bacteria involved in the initiation of dental caries?

A. Streptococcus mutans and Lactobacillus species
B. Salmonella and Listeria species
C. Streptococcus, Lactobacillus, and Salmonella species
D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

5. A nurse is providing teaching to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

A. Albumin in my urine is an indication of normal kidney function.
B. I will keep my HbA1c at five percent.
C. I will have ketones in my urine if my blood glucose is maintained at 190 milligrams per deciliter.
D. I will keep my blood glucose levels between 200 and 212 milligrams per deciliter.

Correct answer: B

Rationale: The correct answer is B. Maintaining an HbA1c level of 5 percent indicates good long-term blood glucose control and understanding of diabetes management. Choice A is incorrect because the presence of albumin in the urine (albuminuria) is actually an indication of kidney damage in diabetes. Choice C is incorrect as ketones in the urine are a sign of inadequate insulin and can occur when blood glucose levels are high, not at a specific level like 190 mg/dL. Choice D is also incorrect as the client should aim to keep blood glucose levels within a tighter range for better control, typically between 80-130 mg/dL before meals and less than 180 mg/dL after meals.
