Correct Answer: B

Rationale: The correct answer is B: Increased urine osmolarity. In hyperglycemia, the body tries to eliminate excess glucose through increased urine output, causing a concentrated urine with high osmolarity. This indicates fluid deficit. Cool, clammy skin (A) may suggest poor perfusion but not fluid volume deficit. Distended neck veins (C) are more indicative of fluid overload. Serum sodium level (D) may be elevated in fluid deficit but does not directly assess volume status like urine osmolarity does.

Correct Answer: C

Rationale: The correct answer is C: Bluish urine. During lymphangiography, a contrast dye is injected into the lymphatic vessels, which can be excreted through the urine, causing it to appear bluish temporarily. This change is harmless and resolves on its own. Incorrect Answers: A: Purplish stools - This is not a common side effect of lymphangiography. B: Redness of the upper part of the feet - Redness is not typically associated with this procedure. D: Coldness of the soles - Coldness is not a known temporary change resulting from lymphangiography.

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Serum potassium level of 5.8 mEq/L) being the best to support a diagnosis of Addison's disease: 1. Addison's disease is characterized by adrenal insufficiency, leading to decreased aldosterone secretion. 2. Decreased aldosterone causes hyperkalemia due to impaired potassium excretion. 3. Elevated serum potassium levels above the normal range (3.5-5.0 mEq/L) are a classic finding in Addison's disease. 4. Therefore, a serum potassium level of 5.8 mEq/L strongly supports the diagnosis of Addison's disease. Summary: - Choice A (BUN level): BUN is not specific to Addison's disease and does not directly relate to adrenal function. - Choice B (Serum sodium level): Hyponatremia is a common finding in Addison's disease, but it is not as specific as hyperkalemia. - Choice D (Blood glucose level): Blood glucose

Correct Answer: B

Rationale: The correct answer is B because providing frequent mouth care to Mr. Franco is important to remove dried blood when the tongue is bitten during a seizure. This is crucial for preventing infection and promoting oral hygiene. Choices A, C, and D are incorrect because the primary reason for mouth care in this case is to address the physical consequences of a seizure, such as tongue biting and potential injury, rather than thirst, tactile stimulation, or prevention of oral mucosal issues related to mouth breathing in a comatose patient.

Correct Answer: D

Rationale: The correct answer is D: Preventing bone injury. In multiple myeloma, bone lesions are common due to bone destruction by abnormal plasma cells. Preventing bone injury is crucial to avoid fractures and bone pain. This can be achieved through careful handling, fall prevention, and avoiding activities that may increase the risk of bone damage. Monitoring respiratory status (A) is not the priority in multiple myeloma. Balancing rest and activity (B) is important but not as critical as preventing bone injury. Restricting fluid intake (C) is not typically necessary unless there are specific indications like renal issues.
