Pathophysiology Final Exam
1. A 40-year-old man has been living with HIV for several years but experienced a significant decrease in his CD4+ levels a few months ago. The patient has just been diagnosed with Mycobacterium avium complex disease. The nurse should anticipate administering which of the following medications?
- A. Clarithromycin
- B. Pyrazinamide
- C. Rifapentine (Priftin)
- D. Azithromycin
Correct answer: A
Rationale: The correct answer is A: Clarithromycin. In the case of Mycobacterium avium complex disease, a common treatment regimen includes a macrolide antibiotic like clarithromycin or azithromycin in combination with other antimicrobials. Clarithromycin is a key component of the treatment due to its effectiveness against Mycobacterium avium complex. Choice B (Pyrazinamide) is not typically part of the standard treatment for this condition. Choice C (Rifapentine) is mainly used in tuberculosis treatment and is not a primary agent for Mycobacterium avium complex disease. Choice D (Azithromycin) is another suitable macrolide antibiotic for treating Mycobacterium avium complex disease but is not the medication typically used first-line.
2. A person is given an attenuated antigen as a vaccine. When the person asks what was given in the vaccine, how should the nurse respond? The antigen is:
- A. Alive, but less infectious
- B. Mutated, but highly infectious
- C. Normal, but not infectious
- D. Inactive, but infectious
Correct answer: A
Rationale: An attenuated antigen used in a vaccine is alive but less infectious, aiming to stimulate an immune response. Choice B is incorrect because an attenuated antigen is not highly infectious. Choice C is incorrect as the antigen is intentionally altered to be less infectious. Choice D is incorrect as an attenuated antigen is not infectious.
3. A patient is starting on finasteride (Proscar) for the treatment of benign prostatic hyperplasia (BPH). What should the nurse include in the patient teaching?
- A. The medication will cure BPH after treatment is complete.
- B. The effects of the medication may take several weeks or months to become noticeable.
- C. The medication may cause increased hair growth.
- D. The medication may decrease libido.
Correct answer: B
Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable. It is important for the nurse to educate the patient about this expected time frame to manage expectations. Choice A is incorrect because finasteride does not cure BPH but helps in managing symptoms. Choice C is incorrect as one of the side effects of finasteride is decreased hair growth. Choice D is incorrect as finasteride may cause a decrease in libido as a side effect.
4. Although stress exposure initiates integrated responses by multiple systems, which system first activates the most important changes?
- A. Pulmonary
- B. Gastrointestinal
- C. Neuroendocrine
- D. Cardiovascular
Correct answer: C
Rationale: The correct answer is C, the Neuroendocrine system. When the body is exposed to stress, the neuroendocrine system plays a crucial role in initiating the body's response. This system, particularly through the hypothalamic-pituitary-adrenal axis, triggers a cascade of physiological responses to stress. Choices A, B, and D are incorrect because while other systems like the cardiovascular and gastrointestinal systems also respond to stress, the neuroendocrine system is primarily responsible for the initial and significant changes in the body's stress response.
5. A staff member asks what leukocytosis means. How should the nurse respond? Leukocytosis can be defined as:
- A. A normal leukocyte count
- B. A high leukocyte count
- C. A low leukocyte count
- D. Another term for leukopenia
Correct answer: B
Rationale: Leukocytosis refers to an abnormally high leukocyte count. This condition is characterized by an elevated number of white blood cells in the bloodstream. Choice A is incorrect because leukocytosis does not refer to a normal leukocyte count. Choice C is incorrect as leukocytosis is not related to a low leukocyte count. Choice D is incorrect as leukopenia is the opposite of leukocytosis, indicating a low white blood cell count.
