Pathophysiology Practice Questions

1. Which disorder is caused by a Staphylococcus aureus organism producing a toxin leading to exfoliation and large blister formation?

Correct answer: B

Rationale: Bullous impetigo is the correct answer because it is caused by a Staphylococcus aureus toxin that leads to exfoliation and the formation of large blisters. Herpes simplex I virus (Choice A) causes cold sores and is not associated with exfoliation and blister formation. Necrotizing fasciitis (Choice C) is a severe skin infection involving the deeper layers of skin and subcutaneous tissues, typically caused by bacteria such as Streptococcus or Clostridium species, not Staphylococcus aureus. Cellulitis (Choice D) is a common bacterial skin infection, but it does not involve exfoliation and blister formation as seen in bullous impetigo.

2. A patient with osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic action of this medication?

Correct answer: A

Rationale: The correct answer is A. Raloxifene works by decreasing bone resorption and increasing bone density. This helps in preventing further bone loss and reducing the risk of fractures in patients with osteoporosis. Choice B is incorrect because raloxifene does not stimulate the formation of new bone, but rather helps to maintain existing bone mass. Choice C is incorrect as raloxifene does not directly increase calcium absorption in the intestines. Choice D is also incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

3. When the body produces antibodies against its own tissue, the condition is called

Correct answer: C

Rationale: The correct answer is C, autoimmunity. Autoimmunity refers to the immune system attacking the body's own tissues. Alloimmunity (choice A) is the immune response to tissues of another individual of the same species. Opsonization (choice B) is the process where pathogens are marked for destruction by immune cells. Hypersensitivity (choice D) refers to excessive or inappropriate immune responses.

4. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What should the nurse include in the patient education?

Correct answer: A

Rationale: Finasteride is expected to reduce the size of the prostate, which should improve urinary symptoms over time, although the effects may take several weeks or months to become noticeable.

5. Which of the following would the nurse expect to see in a client experiencing hypoventilation?

Correct answer: B

Rationale: In hypoventilation, there is inadequate ventilation leading to decreased removal of carbon dioxide. This results in increased carbon dioxide in the bloodstream. The other choices are incorrect because hypoventilation does not improve oxygenation in the alveoli (Choice A), decrease hemoglobin in the bloodstream (Choice C), or decrease carbon dioxide in the alveoli (Choice D).
