The nurse reviews test results for a client and notes that the lymph node biopsy shows the presence of Reed-Sternberg cells. The nurse knows this finding is indicative of which condition?

Choice A reason: Glomerulonephritis is an inflammation of the glomeruli, the filtering units of the kidneys. It can cause damage to the renal tissue and lead to intrinsic acute kidney injury, not prerenal acute kidney injury.

Choice B reason: Fluid volume deficit is a condition in which the body loses more fluid than it takes in. It can cause hypovolemia, which reduces the blood flow to the kidneys and impairs their function. This is the most common cause of prerenal acute kidney injury, which is a result of decreased perfusion to the kidneys.

Choice C reason: Neurogenic bladder is a dysfunction of the bladder caused by a nerve problem. It can affect the ability to store or empty urine. It can cause urinary retention, which increases the pressure in the urinary tract and damages the kidneys. This is a type of postrenal acute kidney injury, which is a result of obstruction to the urine outflow.

Choice D reason: Renal calculus is a solid mass formed from crystals in the urine. It can block the ureter, the tube that carries urine from the kidney to the bladder. It can cause hydronephrosis, which is a swelling of the kidney due to accumulation of urine. This is another type of postrenal acute kidney injury.

Choice A reason: Liver failure is not the most common cause of this type of pain because it is a condition where the liver loses its ability to perform its vital functions, such as detoxifying the blood, producing bile, and metabolizing nutrients. Liver failure can cause symptoms such as jaundice, ascites, or bleeding, but it does not usually cause burning pain in the feet.

Choice B reason: Diabetes mellitus is the most common cause of this type of pain because it is a condition where the blood glucose level is too high, either due to insufficient insulin production or reduced insulin sensitivity. Diabetes mellitus can cause damage to the nerves, especially in the peripheral areas, such as the feet, which is called diabetic neuropathy. Diabetic neuropathy can cause symptoms such as burning pain, numbness, or tingling in the feet, which can worsen at night or with pressure.

Choice C reason: Mercury toxicity is not the most common cause of this type of pain because it is a condition where the body is exposed to high levels of mercury, which is a toxic metal that can be found in some fish, dental fillings, or thermometers. Mercury toxicity can cause damage to the nervous system, causing symptoms such as tremors, memory loss, or mood changes, but it does not usually cause burning pain in the feet.

Choice D reason: Vitamin B12 deficiency is not the most common cause of this type of pain because it is a condition where the body does not have enough vitamin B12, which is a nutrient that is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can cause symptoms such as anemia, fatigue, or weakness, but it does not usually cause burning pain in the feet.
