Pathophysiology Final Exam Questions
Question 1 of 5
A student is feeling inside her backpack to find her mobile phone. There are a number of other items in the bag other than the phone. The nurse knows that which term best describes one's ability to sense the shape and size of an object in the absence of visualization?
Correct Answer: A
Rationale: Stereognosis is the correct answer. It refers to the ability to recognize objects by touch, specifically determining their shape and size without relying on visual cues. Graphesthesia, on the other hand, is the ability to recognize symbols or numbers traced on the skin. Proprioception involves the awareness of body position and movement. Kinesthesia relates to the perception of body movement.
Question 2 of 5
The parents of a 3-year-old boy have brought him to a pediatrician for assessment of the boy's late ambulation and frequent falls. Subsequent muscle biopsy has confirmed a diagnosis of Duchenne muscular dystrophy. Which teaching point should the physician include when explaining the child's diagnosis to his parents?
Correct Answer: A
Rationale: The correct teaching point that the physician should include when explaining Duchenne muscular dystrophy to the parents is that 'Your child may develop breathing difficulties as the disease progresses.' Duchenne muscular dystrophy is a progressive condition that affects muscle strength, including respiratory muscles, leading to breathing difficulties as the disease advances. Choice B is incorrect because while physical therapy and exercise can help maintain muscle function and mobility, they do not cure the condition. Choice C is incorrect because Duchenne muscular dystrophy is a genetic disorder with no known cure. Choice D is incorrect as Duchenne muscular dystrophy is primarily characterized by a lack of dystrophin protein due to genetic mutations, not inflammation in the muscles.
Question 3 of 5
A patient arrives at her follow-up appointment 1 month post-hysterectomy and complains to the nurse that her scars do not seem to be healing properly. Upon inspection, the nurse notices that the scars are raised but still within the boundaries of the original incisions. The nurse tells the patient this kind of dysfunctional wound healing is called:
Correct Answer: A
Rationale: Hypertrophic scarring occurs when a scar is raised but remains within the boundaries of the original wound, unlike keloids, which extend beyond the wound edges. Dehiscence refers to the separation of wound edges, while contracture involves the tightening or constriction of a scar, leading to limited mobility.
Question 4 of 5
Which of the following statements indicates more teaching is needed regarding secondary lymph organs? ________is/are a secondary lymph organ.
Correct Answer: D
Rationale: The correct answer is D, 'The liver.' The liver is not a secondary lymph organ. Secondary lymph organs are primarily involved in the immune response, such as the spleen, Peyer's patches, and adenoids. The spleen filters blood and is essential for immune function. Peyer's patches are located in the small intestine and help protect against pathogens. Adenoids are located in the throat and play a role in immune defense. Therefore, the liver is the incorrect choice as it is not part of the secondary lymph organ system.
Question 5 of 5
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.
