ATI Pathophysiology Exam 2
1. Which of the following is found in clients with Parkinson’s disease?
- A. Mobility and functioning
- B. The liver and kidneys
- C. Too much dopamine in the brain
- D. Skeletal muscle flaccidity
Correct answer: C
Rationale: The correct answer is C: Too much dopamine in the brain. Parkinson's disease is characterized by a deficiency of dopamine in the brain, not an excess. This deficiency leads to the motor symptoms associated with the disease. Choices A, B, and D are incorrect. Mobility and functioning are affected in Parkinson's disease due to the lack of dopamine, not an excess. The liver and kidneys are not directly related to Parkinson's disease. Skeletal muscle flaccidity is not typically a primary symptom of Parkinson's disease, which is more characterized by rigidity and tremors.
2. What condition is a result of Polycythemia Vera, which involves excess red blood cells?
- A. Tissue ischemia & necrosis
- B. Chronic pancreatitis
- C. Low blood pressure & heart rate
- D. Increased numbers of infections
Correct answer: A
Rationale: Polycythemia Vera, characterized by excess red blood cells, can cause tissue ischemia and necrosis due to the increased blood viscosity. This condition restricts blood flow, leading to inadequate oxygen delivery to tissues and subsequent tissue damage. Choices B, C, and D are incorrect because they are not directly associated with the pathophysiology of Polycythemia Vera.
3. Seizures are diagnosed by which of the following?
- A. Electroencephalogram (EEG) and ECG
- B. Seizure symptoms and complete blood count (CBC)
- C. Seizure symptoms and electrocardiogram (ECG)
- D. Seizure symptoms and EEG
Correct answer: D
Rationale: Seizures are most accurately diagnosed by EEG, which measures brain activity. Choice A is incorrect as ECG (electrocardiogram) measures heart activity, not brain activity. Choice B is incorrect as CBC (complete blood count) is a blood test and not used to diagnose seizures. Choice C is incorrect as an ECG (electrocardiogram) also measures heart activity, not brain activity, and is not the primary diagnostic tool for seizures.
4. What tool is used to determine a client’s level of consciousness?
- A. Magnetic resonance imaging (MRI)
- B. Glasgow Coma Scale (GCS)
- C. Central perfusion pressure (CPP)
- D. Intracranial pressure (ICP) monitoring
Correct answer: B
Rationale: The correct answer is B: Glasgow Coma Scale (GCS). The Glasgow Coma Scale is specifically designed to assess a client's level of consciousness by evaluating verbal, motor, and eye-opening responses. Choice A, Magnetic Resonance Imaging (MRI), is a diagnostic imaging tool that provides detailed images of the body's organs and tissues but is not used to assess consciousness levels. Choice C, Central Perfusion Pressure (CPP), and Choice D, Intracranial Pressure (ICP) monitoring, are related to hemodynamic monitoring and intracranial pressure management, not direct assessment of consciousness.
5. Which of the following describes the etiology of a cerebrovascular accident (CVA)?
- A. A blow to the head from a hard object
- B. Lack of blood flow to part of the brain
- C. Excessive exercise, such as running
- D. A ruptured artery in the heart
Correct answer: B
Rationale: The correct answer is B. A cerebrovascular accident (CVA), or stroke, is often caused by a lack of blood flow to part of the brain. This leads to damage in the brain tissue due to the deprived oxygen and nutrients. Choices A, C, and D are incorrect. A blow to the head from a hard object can cause a traumatic brain injury but is not the etiology of a CVA. Excessive exercise like running does not typically lead to a stroke. A ruptured artery in the heart may result in a heart attack, not a cerebrovascular accident.
