ATI Pathophysiology Exam 2
1. Helicobacter pylori (H. pylori) often causes which of the following?
- A. Colon cancer
- B. Hiatal hernia
- C. Peptic ulcer disease
- D. Esophageal varices
Correct answer: C
Rationale: Helicobacter pylori is a bacterium known to cause peptic ulcer disease by weakening the protective lining of the stomach and duodenum, leading to inflammation and ulcers. While chronic H. pylori infection is a risk factor for stomach cancer, it is not directly linked to colon cancer (Choice A), hiatal hernia (Choice B), or esophageal varices (Choice D). Therefore, the correct answer is C.
2. A client has approached the nurse asking for advice on how to deal with his alcohol addiction. The nurse should tell the client that the only effective treatment for alcoholism is:
- A. psychotherapy.
- B. total abstinence.
- C. Alcoholics Anonymous (AA).
- D. aversion therapy.
Correct answer: B
Rationale: The correct answer is B: total abstinence. Total abstinence from alcohol is considered the most effective treatment for alcoholism. This approach eliminates the risk of relapse and helps individuals maintain sobriety. While psychotherapy can be beneficial in addressing underlying issues, total abstinence is crucial in overcoming alcohol addiction. Alcoholics Anonymous (AA) is a supportive group that can complement treatment, but it is not the only effective approach. Aversion therapy aims to create a negative association with alcohol but may not address the underlying causes of addiction, making total abstinence a more comprehensive and recommended approach.
3. DiGeorge syndrome is a primary immune deficiency caused by:
- A. Failure of B cells to mature
- B. Congenital lack of thymic tissue
- C. Failure of formed elements of blood to develop
- D. Selective IgG deficiency
Correct answer: B
Rationale: DiGeorge syndrome is caused by a congenital lack of thymic tissue, which plays a crucial role in T cell development and maturation, leading to immune deficiency. Choice A is incorrect because DiGeorge syndrome primarily affects T cells, not B cells. Choice C is incorrect as it is too broad and not specific to the thymus. Choice D is incorrect as selective IgG deficiency is a different condition unrelated to DiGeorge syndrome.
4. What is the best way to prevent transmission of infectious agents?
- A. Take antibiotics daily
- B. Call the practitioner for herbal supplements
- C. Wash hands
- D. Avoid public areas as much as possible
Correct answer: C
Rationale: The correct answer is C: Wash hands. Washing hands is the most effective way to prevent the transmission of infectious agents. Antibiotics are not effective in preventing infections, and their overuse can lead to antibiotic resistance. Calling a practitioner for herbal supplements is not a primary method for preventing the transmission of infectious agents. Avoiding public areas entirely is impractical and not as effective as proper hand hygiene.
5. A 23-year-old pregnant female visits her primary care provider for her final prenatal checkup. The primary care provider determines that the fetus has developed an infection in utero. Which of the following would be increased in the fetus at birth?
- A. IgG
- B. IgA
- C. IgM
- D. IgD
Correct answer: C
Rationale: The correct answer is IgM. IgM is the first antibody produced in response to an infection and is elevated in a fetus with an in utero infection. IgG is the primary antibody responsible for providing immunity to the fetus and is transferred across the placenta during the third trimester. IgA is mainly found in mucosal areas and colostrum but not significantly elevated in fetal infections. IgD is involved in the development and maturation of B cells but not typically increased in fetal infections.
