Pathophysiology Practice Exam

Correct Answer: B

Rationale: Erythrocytes with an abnormally low concentration of hemoglobin are called hypochromic. Hyperchromic refers to erythrocytes with an abnormally high concentration of hemoglobin. Macrocytic indicates larger than normal red blood cells, while microcytic refers to smaller than normal red blood cells. Therefore, in this scenario, the correct term is hypochromic.

Correct Answer: A

Rationale: The correct answer is A: Jaundice. Fluconazole, an antifungal medication, can rarely cause hepatotoxicity, which may manifest as jaundice. Monitoring for signs of liver dysfunction, such as jaundice, is crucial during fluconazole therapy. Weight gain, iron deficiency anemia, and hematuria are not commonly associated with fluconazole use and are not indications for discontinuing the drug.

Correct Answer: A

Rationale: Impaired erythropoiesis refers to a decreased production of red blood cells. This can lead to anemia, resulting in symptoms like fatigue and increased heart rate (Choice B). However, the question specifically asks about assessment findings suggestive of impaired erythropoiesis. In this context, frequent infections and low neutrophil levels (Choice A) are more directly related to impaired erythropoiesis due to the impact of anemia on the immune system. Frequent infections are common in anemia due to a compromised immune response, and low neutrophil levels can be seen in conditions of impaired erythropoiesis. Agitation and changes in cognition (Choice C) are more indicative of neurological issues, while increased blood pressure and peripheral edema (Choice D) are commonly associated with renal failure but not specifically related to impaired erythropoiesis.

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.

Correct Answer: C

Rationale: The temporal lobe is responsible for processing auditory information, allowing the patient to hear and comprehend while in a coma. The cerebellum is primarily associated with coordination and balance, not auditory processing. The thalamus serves as a relay station for sensory information but is not specifically responsible for auditory processing. The occipital lobe is mainly involved in processing visual information, not auditory functions.
