ATI Pathophysiology Exam 1
1. Which symptoms are typical of asthma?
- A. Chest pain; cough
- B. Diarrhea; wheezing
- C. Wheezing; dyspnea
- D. Tachypnea; constipation
Correct answer: C
Rationale: The correct answer is C: Wheezing and dyspnea are typical symptoms of asthma. Wheezing refers to a high-pitched whistling sound while breathing, and dyspnea is shortness of breath. These symptoms are classic signs of airway obstruction and inflammation seen in asthma. Choice A is incorrect as chest pain is not a typical symptom of asthma, though coughing can occur. Choice B is incorrect as diarrhea is not associated with asthma, while wheezing is a common symptom. Choice D is incorrect as tachypnea (rapid breathing) can occur in asthma, but constipation is not a typical symptom.
2. A 44-year-old man presents with muscle weakness and fatigue. He states that he has experienced difficulty climbing stairs and even holding his arms up to comb his hair. Which test is most likely to help confirm the diagnosis?
- A. Electromyography (EMG)
- B. Nerve conduction studies
- C. Muscle biopsy
- D. Blood test for autoantibodies
Correct answer: A
Rationale: The correct answer is Electromyography (EMG). EMG is commonly used to diagnose conditions involving muscle weakness and fatigue, such as myasthenia gravis. Nerve conduction studies primarily assess nerve function rather than muscle involvement. While a muscle biopsy can provide valuable information, EMG is more specific for evaluating muscle function in this context. A blood test for autoantibodies may be helpful in certain autoimmune conditions but is not the primary test for confirming the diagnosis based on the patient's symptoms of muscle weakness and fatigue.
3. In which of the following cases is dehydration more likely to occur?
- A. A 50-year-old woman who is a bodybuilder
- B. A 50-year-old man who is morbidly obese
- C. A 10-year-old child who is thin
- D. A 30-year-old with multiple sclerosis
Correct answer: B
Rationale: Dehydration is more likely to occur in a 50-year-old man who is morbidly obese due to the increased risk of conditions like diabetes and heart disease that can lead to fluid imbalances. Being morbidly obese can also strain the body's systems, increasing the need for water. The other choices are less likely to experience dehydration as a primary concern. While being a bodybuilder may require strict hydration practices, dehydration is more prevalent in individuals with conditions like obesity.
4. A patient is diagnosed with ischemic heart disease. She is prescribed filgrastim (Neupogen). What effect will this medication provide in the treatment of ischemic heart disease?
- A. Increase platelets
- B. Decrease platelets
- C. Promote angiogenesis
- D. Prevent thrombus formation
Correct answer: C
Rationale: Filgrastim (Neupogen) is a medication that promotes the growth of white blood cells. In the context of ischemic heart disease, promoting angiogenesis, the formation of new blood vessels, can improve blood flow to the heart muscle, reducing ischemia and potentially improving cardiac function. Therefore, the correct answer is C. Choices A and B are incorrect because filgrastim does not directly affect platelet levels. Choice D is also incorrect as filgrastim does not prevent thrombus formation.
5. A 43-year-old man has tested positive for systemic candidiasis, and the care team has decided on IV fluconazole as a first-line treatment. When administering this medication, the nurse should
- A. administer the drug with lactated Ringer's.
- B. infuse the drug no faster than 200 mg/h.
- C. avoid administering the drug through a peripheral IV.
- D. administer prophylactic heparin prior to the fluconazole.
Correct answer: C
Rationale: When administering IV fluconazole, the nurse should avoid administering the drug through a peripheral IV. Fluconazole is known to cause phlebitis and tissue irritation if infused through a peripheral IV line. It is recommended to administer fluconazole through a central venous catheter to reduce the risk of complications. Choices A, B, and D are incorrect as there is no specific recommendation to administer the drug with lactated Ringer's, infuse it at a particular rate, or administer prophylactic heparin prior to fluconazole in this scenario.
