A-55-year old male patient is admitted with a massive GI bleed. The patient is at risk for what type of acute kidney injury?

refer to a condition where significant urinary tract obstruction which in severe or long- standing cases can yield to backup of urine into the kidneys

refer to a condition when direct damage to the kidneys causes a sudden loss in kidney function.

refer to a condition in which the kidneys stop functioning due to internal kidney disease.

refer to a condition in which kidney blood flow may become significantly reduced include those in which a significant amount of fluid has been lost.

Answer and Explanation

The Correct Answer is D

Choice A rationale: This refers to postrenal AKI, which is caused by an obstruction in the urinary tract that prevents urine from leaving the body.

Choice B rationale: This refers to AKI in general and is not specific compared to choice D.

Choice C rationale: This refers to intrinsic AKI, which is caused by damage to the kidney tissue or cells from various causes, such as inflammation, infection, toxins, or ischemia.

Choice D rationale: This is correct because it is pre-renal AKI, a condition in which kidney blood flow may become significantly reduced, including cases where a significant amount of fluid has been lost. This situation suggests potential hypovolemia (low blood volume) due to the massive GI bleed, which can lead to reduced kidney blood flow and subsequent acute kidney injury.

Correct Answer is B

Explanation

Choice A rationale: This is a positive Trousseau's sign, which indicates hypocalcemia or tetany. It is not related to meningitis or meningeal irritation.

Choice B rationale: Kernig's sign is indicated when there is resistance and pain with knee extension and hip flexion, suggesting meningeal irritation.

Choice C rationale: This is a positive Homan's sign, which indicates deep vein thrombosis or phlebitis. It is not related to meningitis or meningeal irritation.

Choice D rationale: This is a sign of nuchal rigidity, which indicates meningeal irritation, but it is not specific to Kernig's sign. Nuchal rigidity can also be caused by other conditions such as cervical arthritis or muscle spasm.

A. Syndrome of Inappropriate Antidiuretic Hormone (SIADH) B. Cushing's syndrome/disease C. Adrenal insufficiency D. Diabetes Insipidus (DI)

Correct Answer is A

Explanation

Choice A rationale: These lab findings, particularly concentrated urine (high specific gravity) and hyponatremia, are consistent with SIADH, where excessive ADH secretion leads to water retention and dilutional hyponatremia.

Choice B rationale: While it can affect sodium levels, Cushing's syndrome typically results in hypernatremia or normal sodium levels rather than hyponatremia.

Choice C rationale: Usually presents with hyponatremia but not specifically with high urine specific gravity or hematocrit.

Choice D rationale: DI is associated with high serum sodium and low urine specific gravity due to excessive excretion of dilute urine.
