Which statement would be correct for a patient with type 2 diabetes who was admitted to the hospital with pneumonia?
the patient must receive insulin therapy to prevent ketoacidosis
the patient has islet cell antibodies that have destroyed the pancreas's ability to produce insulin
the patient may have sufficient endogenous insulin to prevent ketosis but is at risk for hyperosmolar hyperglycemic syndrome
the patient has minimal or absent endogenous insulin secretion and requires daily insulin injections
The Correct Answer is C
Choice A rationale: The patient with type 2 diabetes admitted with pneumonia might not necessarily need insulin therapy to prevent ketoacidosis.
Choice B rationale: Type 2 diabetes doesn't typically involve islet cell antibodies destroying the pancreas's ability to produce insulin.
Choice C rationale: In this scenario, the patient might have enough endogenous insulin to prevent ketosis but could be at risk for hyperosmolar hyperglycemic syndrome due to illness-induced stress.
Choice D rationale: Type 2 diabetes often involves some degree of endogenous insulin secretion, and not all patients require daily insulin injections.

Correct Answer is C
Explanation
Choice A rationale: This is a general description of an imaging test, such as an X-ray, ultrasound, or MRI, which can show the structure of the organs but not the mucosal lining.
Choice B rationale: This is a general description of a blood test, which can show signs of infection, inflammation, or anemia, but not the cause of these problems.
Choice C rationale: This exam is called a colonoscopy, which involves inserting a flexible tube with a camera and light into the anus and advancing it through the colon. A colonoscopy can reveal signs of inflammation, ulcers, bleeding, or narrowing of the intestinal wall that are characteristic of Crohn's disease. A biopsy can also be taken during the procedure to confirm the diagnosis.
Choice D rationale: This is a general description of a urine test, which can show signs of kidney problems, urinary tract infections, or dehydration, but not Crohn's disease.
Correct Answer is B
Explanation
Choice A rationale: Anterior spinal artery syndrome is caused by ischemia of the anterior two-thirds of the spinal cord, resulting in loss of motor function and pain and temperature sensation below the level of the lesion.
Choice B rationale: This is a condition that occurs when the nerve roots in the lower end of the spinal cord are compressed, causing symptoms such as lower back pain, sciatica, saddle anesthesia, bladder and bowel dysfunction, and sexual dysfunction.
Choice C rationale: Horner's syndrome is caused by damage to the sympathetic nerve fibers in the neck or chest, resulting in drooping eyelid, constricted pupil, and lack of sweating on one side of the face.
Choice D rationale: Brown-Séquard syndrome is caused by hemisection of the spinal cord, resulting in ipsilateral loss of motor function and proprioception and contralateral loss of pain and temperature sensation below the level of the lesion.
