Pathophysiology Exam 1 Quizlet
1. What is the most common cause of cancer-related deaths in both men and women?
- A. Lung cancer
- B. Breast cancer
- C. Colorectal cancer
- D. Prostate cancer
Correct answer: A
Rationale: Lung cancer is the leading cause of cancer-related deaths in both men and women globally. It is strongly associated with smoking and exposure to environmental toxins. Breast cancer (choice B) primarily affects women, while colorectal cancer (choice C) and prostate cancer (choice D) are more gender-specific. Colorectal cancer is more common in both men and women but not the leading cause of cancer-related deaths.
2. A nurse is assisting with the development of an informed document for participation in a research study. Which of the following information should the nurse include?
- A. A statement that participants can leave the study at will.
- B. An assignment of the participant to either the experimental or control group.
- C. A list of the clients participating in the study.
- D. A description of the framework the researchers will use to evaluate the data.
Correct answer: A
Rationale: The correct answer is A: 'A statement that participants can leave the study at will.' This information is crucial to include in the informed document to ensure that participants are aware of their right to withdraw from the study at any time without any negative consequences. Choice B is incorrect because participants should not be assigned to experimental or control groups without their knowledge and consent. Choice C is incorrect because disclosing a list of clients participating in the study violates confidentiality. Choice D is incorrect as the description of the data evaluation framework is important but not as critical as ensuring participants know they can leave the study at will.
3. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?
- A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
- B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
- C. Poor nutrition has an adverse effect on the periodontium
- D. Chewing soft, spongy foods stimulates salivary flow
Correct answer: D
Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.
4. What is a life-threatening condition where the heart suddenly stops beating?
- A. Cardiac arrest
- B. Myocardial infarction
- C. Heart failure
- D. Atrial fibrillation
Correct answer: A
Rationale: Cardiac arrest is the correct answer. It is a sudden, unexpected loss of heart function, breathing, and consciousness, typically resulting in death if not treated immediately. Myocardial infarction (choice B) refers to a heart attack caused by a blockage in the coronary arteries. Heart failure (choice C) is a chronic condition where the heart is unable to pump blood efficiently. Atrial fibrillation (choice D) is an irregular and often rapid heart rate that can lead to complications but is not the same as cardiac arrest.
5. A healthcare provider is caring for a group of clients. Which of the following clients is not at risk for pulmonary embolism?
- A. A client who has a BMI of 30
- B. A female client who is postmenopausal
- C. A client who has a fractured femur
- D. A client who has chronic atrial fibrillation
Correct answer: A female client who is postmenopausal
Rationale: Postmenopausal status is not a significant risk factor for pulmonary embolism. Risk factors for pulmonary embolism include obesity (BMI of 30 or higher), immobility such as having a fractured femur, and conditions like chronic atrial fibrillation that increase the risk of blood clot formation. While postmenopausal status may be associated with other health risks, it is not directly linked to an increased risk of pulmonary embolism.
