ATI Nutrition Practice A

Correct Answer: B

Rationale: The correct answer is B, Altered taste sensation. The use of antibiotics is known to cause changes in taste sensation as a side effect, especially when used to treat H. pylori infections. Hemoptysis (Choice A) refers to coughing up blood, and while it can be a symptom of various conditions, it is not typically associated with the use of antibiotics. Flatulence (Choice C) and bloody stools (Choice D) can also occur as gastrointestinal complications, but they are not the most likely side effect when treating H. pylori with antibiotics. Therefore, choices A, C, and D are incorrect.

Correct Answer: D

Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

Correct Answer: D

Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.

Correct Answer: D

Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.

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.
