ATI Pathophysiology Final Exam
1. What should the nurse discuss with a patient with a history of cardiovascular disease regarding the risks of hormone replacement therapy (HRT)?
- A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may improve mood and energy levels.
- D. HRT may decrease the risk of breast cancer.
Correct answer: A
Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT is not typically used to decrease the risk of osteoporosis. Choice C is incorrect as mood and energy level improvements are not the primary risks associated with HRT. Choice D is incorrect because HRT may actually increase the risk of breast cancer in some individuals.
2. Which of the following are signs and symptoms of myocardial infarction?
- A. Persistent chest pain which may radiate to the arm
- B. Brief sternal chest pain on inspiration
- C. Rapid respirations with left-sided weakness and numbness
- D. Left upper quadrant abdominal pain which radiates to the back and shoulder
Correct answer: A
Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.
3. When caring for a patient with systemic lupus erythematosus (SLE), the disease the nurse is dealing with is an example of:
- A. Autoimmunity
- B. Alloimmunity
- C. Homoimmunity
- D. Alleimmunity
Correct answer: A
Rationale: When a nurse cares for a patient with systemic lupus erythematosus (SLE), the nurse is dealing with an autoimmune disease. In autoimmune diseases like SLE, the immune system mistakenly attacks the body's own tissues. Choice A, 'Autoimmunity,' is the correct answer because SLE is an example of the immune system attacking self-antigens, leading to tissue damage and inflammation. Choices B, C, and D are incorrect. Alloimmunity refers to the immune response against foreign antigens from members of the same species, homoimmunity is not a recognized term in immunology, and alleimmunity is not a valid term in this context.
4. How often should a patient be administered a tetanus toxoid?
- A. Every year
- B. Every 10 years
- C. Every 2 years
- D. Every 5 years
Correct answer: B
Rationale: Tetanus toxoid should be administered every 10 years to ensure continued protection against tetanus infection. The correct answer is 'Every 10 years.' Choice A ('Every year') is incorrect as the frequency is too frequent. Choice C ('Every 2 years') is incorrect as it is too frequent for tetanus toxoid administration. Choice D ('Every 5 years') is incorrect as it does not align with the recommended interval for tetanus toxoid booster doses.
5. The signs of thyroid crisis resulting from Graves' disease include:
- A. constipation with gastric distension.
- B. bradycardia and bradypnea.
- C. hyperthermia and tachycardia.
- D. constipation and lethargy.
Correct answer: C
Rationale: Thyroid crisis in Graves' disease typically presents with hyperthermia (high body temperature) and tachycardia (rapid heart rate). These symptoms are a result of excessive thyroid hormone production and can lead to life-threatening complications if not promptly addressed. Choices A, B, and D are incorrect because constipation with gastric distension, bradycardia and bradypnea, and constipation and lethargy are not typical signs of a thyroid crisis in Graves' disease.
