ATI Proctored Nutrition Exam

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.

Correct Answer: B

Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.

Correct Answer: C

Rationale: The correct answer is C: whole grain bread. The WIC program aims to provide nutritious foods to support a healthy diet during pregnancy. Whole grain bread is a good source of fiber and essential nutrients. Choice A, lean beef, is a protein source but may not be as versatile as whole grain bread in providing a variety of nutrients essential during pregnancy. Choice B, fruit-flavored yogurt, may contain added sugars and may not offer the same level of essential nutrients as whole grain bread. Choice D, refried beans, is a good source of protein and fiber, but whole grain bread is often a staple recommended in pregnancy for its nutritional benefits.

Correct Answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.

Correct Answer: B

Rationale: The most appropriate nursing diagnosis for a patient with heart failure is 'fluid volume excess.' In heart failure, the heart's reduced pumping ability leads to fluid retention, causing an excess of fluid in the body. This can result in symptoms such as edema, shortness of breath, and weight gain. 'Risk for infection,' 'impaired body temperature,' and 'ineffective airway clearance' are not the most appropriate nursing diagnoses for a patient with heart failure as they do not directly relate to the pathophysiology and common issues seen in heart failure patients.
