ATI Pathophysiology Exam 2
1. Which of the following describes the pathophysiology of exercise-induced asthma?
- A. Bronchospasm after exercise
- B. IgE-mediated inflammatory response to antigen
- C. Bronchoconstriction after ingesting high-allergen foods
- D. Increased mucus production due to a genetic mutation
Correct answer: A
Rationale: The correct answer is A: 'Bronchospasm after exercise.' Exercise-induced asthma involves the narrowing of the airways (bronchospasm) triggered by physical activity. This bronchospasm leads to symptoms such as coughing, wheezing, and shortness of breath. Choices B, C, and D are incorrect because exercise-induced asthma is not primarily caused by an IgE-mediated inflammatory response to an antigen, bronchoconstriction after ingesting high-allergen foods, or increased mucus production due to a genetic mutation.
2. What is a common factor related to all forms of heart failure?
- A. Peripheral edema
- B. Pulmonary edema
- C. Reduced cardiac output
- D. Jugular vein distention
Correct answer: C
Rationale: The correct answer is C: Reduced cardiac output. All forms of heart failure share this common factor, which occurs when the heart is unable to pump enough blood to meet the body's needs. Choices A, B, and D are incorrect. While peripheral edema and pulmonary edema can be symptoms of heart failure, they are not universal to all forms. Jugular vein distention is a sign of right heart failure, not a common factor across all types of heart failure.
3. What long-term risks should the nurse discuss with a patient starting on hormone replacement therapy (HRT)?
- A. HRT is associated with increased risks of cardiovascular events and breast cancer, so these risks should be discussed with the patient.
- B. HRT can improve mood and energy levels, but it also increases the risk of osteoporosis.
- C. HRT can increase the risk of venous thromboembolism, so patients should undergo regular screening.
- D. HRT decreases the risk of fractures, but it also increases the risk of developing diabetes.
Correct answer: A
Rationale: The correct answer is A. When starting on hormone replacement therapy (HRT), the nurse should discuss the increased risks of cardiovascular events and breast cancer with the patient. These risks are important to consider to make an informed decision. Choice B is incorrect as HRT does not increase the risk of osteoporosis; in fact, it may help prevent it. Choice C is incorrect as while HRT can increase the risk of venous thromboembolism, regular screening is not the primary focus for discussion. Choice D is incorrect as HRT does not decrease the risk of fractures and is not primarily associated with an increased risk of developing diabetes.
4. What causes atherosclerotic plaques to form initially?
- A. Interruption of blood flow to the brain
- B. Injury to the coronary artery endothelium
- C. Administration of statin medications
- D. Poor dietary modifications
Correct answer: B
Rationale: Atherosclerotic plaques form initially due to injury to the coronary artery endothelium, which triggers a cascade of events leading to plaque buildup. Choice A is incorrect because atherosclerotic plaques do not form due to an interruption of blood flow to the brain. Choice C is incorrect as statin medications are actually used to help lower cholesterol and reduce the risk of plaque formation. Choice D is incorrect as poor dietary modifications can contribute to atherosclerosis but are not the initial cause of plaque formation.
5. A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse emphasize about the risks associated with this therapy?
- A. HRT is associated with an increased risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
- B. HRT may improve mood and energy levels, but it also increases the risk of osteoporosis.
- C. HRT can decrease the risk of fractures, but it also increases the risk of developing diabetes.
- D. HRT may increase the risk of breast cancer, so regular mammograms are essential.
Correct answer: A
Rationale: HRT is associated with an increased risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur.
