Pathophysiology Practice Exam
1. 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.
2. When the body produces antibodies against its own tissue, the condition is called:
- A. Alloimmunity
- B. Opsonization
- C. Autoimmunity
- D. Hypersensitivity
Correct answer: C
Rationale: Autoimmunity is the correct term for a condition where the body's immune system mistakenly targets its own tissues. Alloimmunity (Choice A) refers to an immune response against foreign tissue. Opsonization (Choice B) is a process where pathogens are marked for destruction by immune cells. Hypersensitivity (Choice D) involves an exaggerated immune response against antigens.
3. Which of the following accurately describes the pathophysiology of asthma?
- A. Chronic inflammation of the bronchial lining
- B. Narrowing of the airway due to bronchoconstriction
- C. Damage to alveoli reducing lung elasticity
- D. Overproduction of mucus by the goblet cells
Correct answer: B
Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.
4. A 51-year-old woman has the following clinical findings: thin hair, exophthalmos, hyperreflexia, and pretibial edema. These findings are consistent with:
- A. Subacute thyroiditis.
- B. Autoimmune thyroiditis.
- C. Graves disease.
- D. Hashimoto’s disease.
Correct answer: C
Rationale: The clinical findings of thin hair, exophthalmos, hyperreflexia, and pretibial edema are classic features of Graves disease, an autoimmune disorder that results in hyperthyroidism. Exophthalmos (bulging eyes) and pretibial edema (swelling in the lower legs) are particularly associated with Graves disease due to the autoimmune stimulation of the thyroid gland, leading to increased thyroid hormone production. Subacute thyroiditis (Choice A) typically presents with neck pain and tenderness, while autoimmune thyroiditis (Choice B) is commonly known as Hashimoto's thyroiditis, which presents with hypothyroidism symptoms. Hashimoto's disease (Choice D) is characterized by goiter and hypothyroidism, which contrasts with the hyperthyroidism seen in this patient.
5. A patient has been prescribed clomiphene citrate (Clomid) for infertility. What should the nurse include in the teaching plan about the use of this medication?
- A. Clomiphene is taken daily for 5 days at the beginning of the menstrual cycle.
- B. Clomiphene is taken once daily throughout the menstrual cycle.
- C. Clomiphene is taken twice daily for 5 days at the end of the menstrual cycle.
- D. Clomiphene is taken three times daily for 10 days at the beginning of the menstrual cycle.
Correct answer: A
Rationale: Corrected Rationale: Clomiphene is typically taken daily for 5 days at the beginning of the menstrual cycle to stimulate ovulation. Choice A is the correct answer because it aligns with the standard dosing regimen for clomiphene citrate. Choices B, C, and D provide incorrect information about the dosing schedule for clomiphene, which can lead to ineffective treatment and potential side effects. Choice B suggests continuous daily intake, which is not the standard practice for clomiphene. Choice C and D mention different dosing frequencies and timings, which are not in line with the typical protocol for using clomiphene for infertility.
