Proctored Nutrition ATI

Correct Answer: A

Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.

Correct Answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

Correct Answer: A

Rationale: Both statements are true. Poor nutrition can affect tooth development and increase the risk of dental caries in children.

Correct Answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. The DASH diet is specifically designed to control hypertension by reducing sodium intake, managing blood pressure, and promoting overall cardiovascular health. Choice B, Diabetes mellitus, is managed through monitoring blood sugar levels and a balanced diet rich in whole grains, fruits, and vegetables. Choice C, Parkinson's disease, is a neurological disorder that is not primarily managed through diet modifications. Choice D, Anemia, is a condition characterized by a lack of healthy red blood cells and is typically managed by addressing the underlying cause and sometimes iron supplementation, not by the methods mentioned in the question.
