ATI Pathophysiology

1. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?

Correct answer: A

Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.

2. A male patient is receiving androgen therapy for hypogonadism. What laboratory tests should the nurse monitor during this therapy?

Correct answer: A

Rationale: During androgen therapy for hypogonadism, it is important to monitor liver function tests. Androgens can affect the liver, potentially leading to liver dysfunction. Monitoring liver function tests helps in early detection of any liver abnormalities. Kidney function tests (Choice B) are not typically affected by androgen therapy. Prostate-specific antigen (PSA) levels (Choice C) may be monitored for conditions like prostate cancer, but it is not directly related to androgen therapy for hypogonadism. A complete blood count (CBC) (Choice D) may not show specific changes related to androgen therapy for hypogonadism.

3. A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?

Correct answer: C

Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.

4. Which of the following types of vitamin or mineral deficiency can cause megaloblastic anemia and is associated with lower extremity paresthesias?

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.

5. Anemia of chronic inflammation is generally classified as:

Correct answer: D

Rationale: Anemia of chronic inflammation is typically characterized by normochromic (normal hemoglobin content) and normocytic (normal cell size) red blood cells. Choice A, hypochromic and microcytic, is incorrect because hypochromic refers to reduced hemoglobin content and microcytic refers to smaller than normal red blood cells, which are not typically seen in anemia of chronic inflammation. Choice B, hypochromic and macrocytic, is also incorrect as macrocytic refers to larger than normal red blood cells. Choice C, normochromic and microcytic, is incorrect because microcytic red blood cells are smaller than normal. Therefore, the correct classification for anemia of chronic inflammation is normochromic and normocytic.
