Final Exam Pathophysiology
1. A 5-year-old male was diagnosed with normocytic-normochromic anemia. Which of the following anemias does the nurse suspect the patient has?
- A. Sideroblastic anemia
- B. Hemolytic anemia
- C. Pernicious anemia
- D. Iron deficiency anemia
Correct answer: B
Rationale: The correct answer is B, Hemolytic anemia. Normocytic-normochromic anemia is a type of anemia characterized by normal-sized and normal-colored red blood cells. Hemolytic anemia is a condition where red blood cells are destroyed prematurely, leading to normocytic-normochromic anemia. Sideroblastic anemia (Choice A) is characterized by ringed sideroblasts in the bone marrow. Pernicious anemia (Choice C) is due to vitamin B12 deficiency. Iron deficiency anemia (Choice D) is characterized by microcytic-hypochromic red blood cells.
2. A nurse is providing education to a patient starting hormone replacement therapy (HRT) for menopausal symptoms. What should the nurse emphasize regarding the long-term risks associated with HRT?
- A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may improve mood and energy levels.
- D. HRT may decrease the risk of breast cancer.
Correct answer: A
Rationale: HRT is associated with an increased risk of cardiovascular events, including heart attack and stroke, particularly with long-term use.
3. A 30-year-old woman presents with joint pain, a malar rash, and photosensitivity. Which of the following is the most likely diagnosis?
- A. Rheumatoid arthritis
- B. Systemic lupus erythematosus
- C. Psoriatic arthritis
- D. Dermatomyositis
Correct answer: B
Rationale: The correct answer is B: Systemic lupus erythematosus. Joint pain, a malar rash, and photosensitivity are classic symptoms of systemic lupus erythematosus. Choice A, Rheumatoid arthritis, is incorrect as it typically presents with symmetric joint involvement and morning stiffness. Psoriatic arthritis (Choice C) is characterized by joint pain associated with psoriasis, which is not described in the case. Dermatomyositis (Choice D) presents with muscle weakness, skin rash, and elevated muscle enzymes, different from the symptoms presented in the case.
4. Hematopoiesis occurs primarily in the bone marrow. What cells are formed during this process?
- A. Pancreatic beta cells
- B. Red blood cells
- C. Gastric parietal cells
- D. Neurons and glial cells
Correct answer: B
Rationale: The correct answer is B: Red blood cells. Hematopoiesis is the process of blood cell formation that primarily occurs in the bone marrow. Red blood cells are one of the main cell types formed during this process. Pancreatic beta cells (Choice A), gastric parietal cells (Choice C), and neurons and glial cells (Choice D) are not formed during hematopoiesis. Pancreatic beta cells are involved in insulin production, gastric parietal cells secrete gastric acid, and neurons and glial cells are part of the nervous system.
5. Which of the following nursing diagnoses would provide the most plausible indication for the use of epoetin alfa (Epogen) in a patient with renal failure?
- A. Risk for infection related to decreased erythropoiesis
- B. Activity intolerance related to decreased oxygen-carrying capacity
- C. Powerlessness related to sequelae of renal failure
- D. Ineffective breathing pattern related to inadequate erythropoietin synthesis
Correct answer: B
Rationale: The correct answer is B. In a patient with renal failure, the use of epoetin alfa (Epogen) is primarily aimed at addressing the decreased oxygen-carrying capacity due to impaired erythropoiesis. Epoetin alfa is a medication that stimulates red blood cell production, thereby improving the oxygen-carrying capacity of the blood. This would directly address the activity intolerance commonly seen in patients with renal failure. Choices A, C, and D are incorrect because they do not directly relate to the primary purpose of using epoetin alfa in this context. Risk for infection, powerlessness, and ineffective breathing pattern are important considerations in the care of a patient with renal failure, but they are not the primary indications for using epoetin alfa.
