ATI Pathophysiology Exam 1
1. What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
2. A male patient receiving androgen therapy is concerned about the risk of prostate cancer. What should the nurse explain regarding this risk?
- A. Finasteride has been shown to lower the risk of developing prostate cancer.
- B. Finasteride does not affect the risk of prostate cancer.
- C. Finasteride may increase the risk of developing prostate cancer, so regular screenings are recommended.
- D. Finasteride has no effect on the risk of prostate cancer, so regular screenings are unnecessary.
Correct answer: A
Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. However, regular screenings are still recommended to monitor for any potential issues. Choice B is incorrect because finasteride has been associated with a reduced risk of developing prostate cancer. Choice C is incorrect as finasteride is not known to increase the risk of prostate cancer; in fact, it has shown a protective effect. Choice D is incorrect because while finasteride may lower the risk of prostate cancer, regular screenings are still necessary to ensure early detection and treatment if needed.
3. A 50-year-old woman has had a relapse of her multiple sclerosis (MS) after several years of being symptom-free. Which of the following factors is most likely to have contributed to her relapse?
- A. Emotional stress
- B. Dietary indiscretion
- C. Physical overexertion
- D. Adequate rest and relaxation
Correct answer: C
Rationale: The correct answer is C: Physical overexertion. In individuals with multiple sclerosis (MS), physical overexertion can exacerbate symptoms and contribute to a relapse. It is important for individuals with MS to balance physical activity to avoid triggering symptom reoccurrence. Choices A, B, and D are less likely to have directly contributed to the relapse. Emotional stress and dietary indiscretion may play a role in exacerbating symptoms in some individuals, but physical overexertion is more commonly associated with MS relapses. Adequate rest and relaxation are important for overall well-being but are not typically linked to MS relapses.
4. A patient with systemic candidiasis has been prescribed flucytosine. The nurse should be aware of the need to administer this drug with which of the following?
- A. Vitamin D and calcium supplements
- B. Fluconazole (Diflucan)
- C. Amphotericin B
- D. Penicillin G
Correct answer: C
Rationale: The correct answer is C: Amphotericin B. When treating systemic candidiasis, Amphotericin B is the drug of choice, not flucytosine. Amphotericin B is an antifungal medication used to treat severe fungal infections like systemic candidiasis. Choices A, B, and D are incorrect because vitamin D and calcium supplements, fluconazole, and penicillin G are not the drugs of choice for treating systemic candidiasis.
5. A 30-year-old male has been brought to the emergency department by his wife because of a severe headache, nausea, vomiting, and fever. A lumbar puncture is performed, and cerebrospinal fluid (CSF) analysis reveals a high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs). Which organism is the most likely cause of these findings?
- A. Streptococcus pneumoniae
- B. Neisseria meningitidis
- C. Escherichia coli
- D. Listeria monocytogenes
Correct answer: A
Rationale: The cerebrospinal fluid (CSF) analysis findings of high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs) are classic for bacterial meningitis. Among the choices, Streptococcus pneumoniae is the most likely cause in this case. Streptococcus pneumoniae is a common cause of bacterial meningitis in adults, especially presenting with symptoms such as severe headache, nausea, vomiting, and fever. Neisseria meningitidis is another common cause of bacterial meningitis but is more frequently associated with a different CSF profile. Escherichia coli is a common cause of neonatal meningitis, not typically seen in a 30-year-old male. Listeria monocytogenes is more commonly associated with meningitis in immunocompromised individuals and neonates, and typically presents differently in CSF analysis.
