Correct Answer: C

Rationale: In catatonic schizophrenia, immobile posturing is a common clinical finding where the patient may maintain a rigid or bizarre posture for prolonged periods. Crying (Choice A) is not typically associated with catatonic schizophrenia. Self-mutilation (Choice B) is more commonly seen in conditions like borderline personality disorder. Repetitious activities (Choice D) are not a hallmark symptom of catatonic schizophrenia.

Correct Answer: D

Rationale: The correct answer is D: Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates red blood cell production in the bone marrow. Iron-deficiency anemia (choice A) is more commonly caused by insufficient dietary iron intake or chronic blood loss. Vitamin B12 deficiency anemia (choice B) is usually due to inadequate dietary intake, malabsorption, or pernicious anemia. Aplastic anemia (choice C) is a bone marrow failure disorder characterized by pancytopenia (decreased red blood cells, white blood cells, and platelets) rather than a deficiency in erythropoietin production.

Correct Answer: C

Rationale: The correct answer is C: 'Maintain the health of the Army and preserve its combat effectiveness.' This mission statement reflects the primary goal of the Army Medical Department, which is to ensure that military personnel remain healthy and fit for duty to preserve the Army's fighting strength. Choices A, B, and D are incorrect because they do not capture the core purpose of the Army Medical Department, which is focused on the health and readiness of the military forces, rather than performing annual physical examinations, responding to disasters, or providing education and training.

Correct Answer: D

Rationale: The correct answer is D, Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates the bone marrow to produce red blood cells. Choices A, B, and C are incorrect. Iron-deficiency anemia is characterized by low iron levels, vitamin B12 deficiency anemia by inadequate vitamin B12, and aplastic anemia by bone marrow failure.

Correct Answer: A

Rationale: The correct answer is A: Medical-surgical nursing. In the resident M6 Practical Nurse Course, students are expected to achieve entry-level competencies in medical-surgical nursing. This area of nursing focuses on caring for adult patients with a variety of medical conditions. Obstetric and newborn nursing (choice B), pediatric nursing (choice C), and trauma nursing (choice D) are specialized areas within nursing that are not typically covered in entry-level practical nurse courses, making them incorrect choices.
