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 A
Explanation
Choice A rationale: The Tensilon test involves injecting edrophonium, and in myasthenia gravis, temporary improvement in muscle strength confirms the diagnosis by demonstrating increased acetylcholine activity at the neuromuscular junction.
Choice B rationale: This describes the pathophysiology of myasthenia gravis but doesn’t directly confirm the diagnosis via the Tensilon test.
Choice C rationale: While this may be seen in myasthenia gravis, the Tensilon test specifically aims to observe improved muscle strength after administration.
Choice D rationale: While the presence of these antibodies is a characteristic of myasthenia gravis, the Tensilon test is used to assess the immediate response to the medication for diagnostic confirmation.
Correct Answer is B
Explanation
Choice A rationale: This test is not specific for confirming osteoporosis.
Choice B rationale: This test is called a bone mineral density (BMD) test or a dual-energy X-ray absorptiometry (DXA) scan. It measures how much calcium and other minerals are in a segment of bone.
Choice C rationale: This test is not specific for confirming osteoporosis.
Choice D rationale: This test is not specific for confirming osteoporosis.
