Tuberculosis about new prescription for rifampin- indicates an understanding of teaching?

Correct Answer: B

Rationale: The correct answer is B, as rifampin can cause skin and/or urine discoloration, turning them reddish-orange. This is a common side effect known as rifampin-induced discoloration. Choice A is incorrect because blurry vision is an adverse effect of ethambutol, not rifampin. Choice C is incorrect as rifampin does not improve hearing. Choice D is incorrect as sunlight sensitivity is not associated with rifampin. Therefore, understanding the potential side effect of skin discoloration is crucial for patient education regarding the new prescription for rifampin.

Correct Answer: A

Rationale: The correct answer is A: Crohn disease. Crohn disease is an autoimmune disorder that primarily affects the gastrointestinal tract, causing inflammation and damage to the digestive system. It is characterized by symptoms such as abdominal pain, diarrhea, and weight loss. The other choices (B, C, D) are incorrect because Guillain-Barré syndrome affects the peripheral nervous system, Addison disease affects the adrenal glands, and Sjögren syndrome affects the exocrine glands, not the gastrointestinal system. Crohn disease specifically targets the gastrointestinal system, making it the most appropriate choice among the options provided.

Correct Answer: D

Rationale: The correct answer is D: Petechiae and purpura. Thrombocytopenia is a condition characterized by low platelet count, leading to impaired blood clotting. Petechiae are small red or purple spots on the skin caused by bleeding into the skin from broken capillaries. Purpura refers to larger purple patches caused by bleeding under the skin. In thrombocytopenia, the lack of platelets results in the inability to form clots, leading to bleeding in small vessels. Choices A, B, and C are incorrect because infection, pruritus, and scarring are not typically associated with bleeding due to thrombocytopenia.

Correct Answer: B

Rationale: The correct answer is B: Overactive. In systemic lupus erythematosus, the immune system is hyperactive, leading to the production of autoantibodies that attack healthy tissues. This results in inflammation and tissue damage throughout the body. The other choices are incorrect because A (Underactive) does not align with the autoimmune nature of lupus, C (Inactive) is not true as there is ongoing immune system activity in lupus, and D (None of the above) is not accurate as the immune system in lupus is indeed overactive.

Correct Answer: D

Rationale: The correct answer is D. Platelets are responsible for blood clotting, which stops bleeding by forming a clot over the bleeding area. This explanation is most suitable for an 8-year-old child with hemophilia as it directly addresses how platelets help in stopping bleeding, which is a common concern for individuals with hemophilia. Choice A is incorrect because platelets do not directly prevent infection. Choice B is incorrect as platelets are actually solid components of blood, not the liquid portion. Choice C is incorrect as it describes the function of red blood cells, not platelets. Therefore, choice D is the best description of platelets for the child to understand their role in stopping bleeding.
