Pathophysiology Final Exam

1. An oncology nurse is providing care for an adult patient who is currently immunocompromised. The nurse is aware of the physiology involved in hematopoiesis and immune function, including the salient role of cytokines. What is the primary role of cytokines in maintaining homeostasis?

Correct answer: B

Rationale: The primary role of cytokines in maintaining homeostasis is to perform a regulatory function in the development of diverse blood cells. Cytokines act as signaling molecules that regulate the immune response and hematopoiesis. Choice A is incorrect because cytokines do not perform phagocytosis; they regulate immune responses. Choice C is incorrect because while cytokines are involved in the formation of some blood cells, they are not considered the basic 'building blocks' of all blood cells. Choice D is incorrect because cytokines are not formed in response to antibodies, but rather play a role in the immune response to various stimuli.

2. Which of the following is a clinical manifestation in a patient with renal impairment associated with polycystic kidney disease?

Correct answer: D

Rationale: The correct answer is D: Palpable kidneys. Polycystic kidney disease often leads to the development of multiple fluid-filled cysts within the kidneys, causing them to enlarge. Enlarged kidneys can be palpated during a physical examination. Choices A, B, and C are incorrect. Suprapubic pain is not a typical clinical manifestation of polycystic kidney disease. Periorbital edema is more commonly associated with conditions like nephrotic syndrome or heart failure. Low serum creatinine level is not expected in patients with renal impairment due to polycystic kidney disease; instead, elevated serum creatinine levels are more likely.

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

Correct answer: B

Rationale: The correct answer is B. Raloxifene works by decreasing bone resorption and increasing bone density, which helps in the prevention and treatment of osteoporosis. Choice A is incorrect as raloxifene does not directly stimulate the formation of new bone. Choice C is incorrect because raloxifene does not primarily affect calcium absorption in the intestines. Choice D is incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

4. What is the best method to identify which type of stroke the client has?

Correct answer: D

Rationale: The correct answer is to obtain a cranial computerized tomogram (CT) STAT. A cranial CT scan is the best method to quickly identify the type of stroke a client is experiencing. Options A, B, and C are not appropriate for identifying the type of stroke as they are not specific to assessing stroke types.

5. An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?

Correct answer: A

Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.
