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: Increased serum hydrostatic pressure is not the best explanation for the edema because it is caused by fluid overload, not malnutrition. Fluid overload can result from heart failure, kidney failure, or excessive fluid intake.

Choice B reason: Increased kidney filtration pressure is not the best explanation for the edema because it is caused by increased blood flow to the kidneys, not malnutrition. Increased blood flow to the kidneys can result from hypertension, diabetes, or renal artery stenosis.

Choice C reason: Decreased capillary osmotic pressure is the best explanation for the edema because it is caused by low plasma protein levels, which are common in malnutrition. Low plasma protein levels reduce the force that pulls fluid back into the capillaries from the interstitial space, leading to fluid accumulation in the tissues.

Choice D reason: Intracellular dehydration is not the best explanation for the edema because it is caused by loss of water from the cells, not malnutrition. Loss of water from the cells can result from hypernatremia, hyperglycemia, or osmotic diuresis.

Choice A reason: Uric acid is the most common type of renal calculi in clients with gout because it is a condition where the blood has a high level of uric acid, which is a waste product that results from the breakdown of purines, which are substances found in some foods and drinks, such as meat, seafood, and beer. Uric acid can form crystals in the joints, causing inflammation and pain, which is known as gout. Uric acid can also form crystals in the urine, causing kidney stones, which are hard deposits of minerals and salts that can block the urinary tract and cause symptoms such as severe pain, blood in the urine, nausea, and fever.

Choice B reason: Struvite is not the most common type of renal calculi in clients with gout because it is a condition where the urine has a high level of ammonia, which is a chemical that results from the breakdown of urea, which is a waste product that is produced by the liver and excreted by the kidneys. Ammonia can form crystals in the urine, along with magnesium, phosphate, and carbonate, creating struvite stones, which are large and staghorn-shaped stones that can fill the entire kidney or the ureter. Struvite stones are usually associated with urinary tract infections, which are caused by bacteria that produce enzymes that increase the urine pH and the ammonia level.

Choice C reason: Cystine is not the most common type of renal calculi in clients with gout because it is a condition where the urine has a high level of cystine, which is an amino acid that is a building block of proteins. Cystine can form crystals in the urine, causing kidney stones, which are rare and hereditary. Cystine stones are caused by a genetic disorder that affects the transport of cystine and other amino acids in the kidneys, resulting in excessive excretion of cystine in the urine.

Choice D reason: Calcium oxalate is not the most common type of renal calculi in clients with gout because it is a condition where the urine has a high level of calcium and oxalate, which are substances that are normally present in the diet and the body. Calcium and oxalate can form crystals in the urine, causing kidney stones, which are the most common type of kidney stones in the general population, but not in clients with gout. Calcium oxalate stones can be caused by various factors, such as dehydration, high intake of animal protein, low intake of fluids, and certain medications.
