MSN 570 Advanced Pathophysiology Final 2024 - Nurselytic

Correct Answer: C

Rationale: The correct answer is dark urine. Rhabdomyolysis is a condition characterized by the breakdown of muscle tissue, leading to the release of myoglobin into the bloodstream. Myoglobin can cause the urine to appear dark or tea-colored, a condition known as myoglobinuria. This is a classic symptom of rhabdomyolysis.

Choices A, B, and D are incorrect as they do not typically present as direct symptoms of rhabdomyolysis. Paresthesias refer to abnormal sensations like tingling or numbness, bone pain is not a primary symptom of rhabdomyolysis, and diarrhea is not a common complaint associated with this condition.

Correct Answer: A

Rationale: Crohn's disease is a type of inflammatory bowel disease that can affect any part of the digestive tract. Right lower quadrant cramping is consistent with Crohn's disease as it commonly involves the terminal ileum, which is located in the right lower quadrant of the abdomen. Severe bloody diarrhea is more characteristic of ulcerative colitis, another type of inflammatory bowel disease. Nausea and vomiting are not specific symptoms of Crohn's disease. Crohn's disease can affect any part of the digestive tract, not just the rectum, so it is not accurate to say it mostly affects the rectum.

Correct Answer: C

Rationale: The correct answer is C: Complement, clotting, and kinin systems. These are the three main plasma protein inflammatory mediator systems. The complement system helps in inflammation and immune responses, the clotting system is involved in blood coagulation, and the kinin system regulates inflammation and blood pressure.
Choice A is incorrect because interferon is not part of the plasma protein inflammatory mediator systems.
Choice B is incorrect because the fibrinolytic system is not a primary inflammatory mediator system.
Choice D is incorrect because acute phase reactants are not part of the plasma protein inflammatory mediator systems.

Correct Answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 deficiency can lead to megaloblastic anemia, a condition characterized by the production of abnormally large and immature red blood cells. Lower extremity paresthesias, such as tingling or numbness, are common neurological symptoms associated with vitamin B12 deficiency. Folate deficiency can also cause megaloblastic anemia but is not typically linked to lower extremity paresthesias. Iron deficiency leads to microcytic anemia, not megaloblastic anemia. Vitamin K deficiency is associated with bleeding tendencies, not megaloblastic anemia or paresthesias.

Correct Answer: B

Rationale: Neutrophils are the first responders to a bacterial infection. They are phagocytes that engulf and destroy bacteria, playing a crucial role in the early stages of the immune response. Eosinophils are primarily involved in combating parasitic infections and allergic reactions, not bacterial infections. Leukotrienes are signaling molecules that contribute to inflammation and immune responses, but they are not cells. Monocytes are another type of white blood cell that differentiates into macrophages and dendritic cells, playing a role in immune response but not as immediate as neutrophils.
