The nurse provides care for a client who reports burning pain, which is worse at night, in both feet. The client states the pressure of the sheets on the feet is "unbearable". Which reason is the most common cause of this type of pain?

Choice A reason: Decreased skin turgor is not the most common clinical manifestation of nephrotic syndrome because it is a sign of dehydration, not nephrotic syndrome. Dehydration is a condition where the body loses more fluid than it takes in, which can cause the skin to lose its elasticity and firmness. Dehydration can be caused by various factors, such as vomiting, diarrhea, fever, or excessive sweating.

Choice B reason: Hypoalbuminemia is the most common clinical manifestation of nephrotic syndrome because it is a condition where the blood has a low level of albumin, which is a protein that helps maintain the fluid balance in the body. Nephrotic syndrome is a kidney disorder that causes the kidneys to leak large amounts of protein into the urine, which reduces the amount of protein in the blood. Albumin is the most abundant protein in the blood, and it helps to keep the fluid in the blood vessels, preventing it from leaking into the tissues. When the albumin level is low, the fluid can escape from the blood vessels and cause edema, which is swelling of the body parts.

Choice C reason: Decreased serum cholesterol is not the most common clinical manifestation of nephrotic syndrome because it is a condition where the blood has a low level of cholesterol, which is a type of fat that is needed for the synthesis of hormones, bile acids, and cell membranes. Decreased serum cholesterol is not a common finding in nephrotic syndrome, because the liver tends to produce more cholesterol to compensate for the loss of protein in the urine. This can lead to hypercholesterolemia, which is a condition where the blood has a high level of cholesterol, which can increase the risk of cardiovascular diseases.

Choice D reason: Increased serum sodium is not the most common clinical manifestation of nephrotic syndrome because it is a condition where the blood has a high level of sodium, which is an electrolyte that helps regulate the fluid and acid-base balance in the body. Increased serum sodium is not a common finding in nephrotic syndrome, because the kidneys tend to excrete more sodium in the urine to balance the fluid loss caused by hypoalbuminemia. This can lead to hyponatremia, which is a condition where the blood has a low level of sodium, which can cause symptoms such as confusion, weakness, seizures, and coma.

Choice A reason: Compression of white matter in the brain and spinal cord is not the best explanation because it is a condition that affects the transmission of nerve impulses, not the perception of sensory stimuli. White matter is the part of the nervous system that consists of myelinated axons, which are the extensions of nerve cells that carry electrical signals from one cell to another. Compression of white matter can be caused by various factors, such as tumors, trauma, or inflammation, and can result in symptoms such as weakness, numbness, or paralysis.

Choice B reason: Decreased levels of gamma-aminobutyric acid (GABA) in the brain stem is not the best explanation because it is a condition that affects the regulation of muscle tone, not the perception of sensory stimuli. GABA is a neurotransmitter, which is a chemical messenger that transmits signals between nerve cells. GABA is an inhibitory neurotransmitter, which means that it reduces the activity of the nerve cells that it binds to. GABA is mainly found in the brain stem, which is the part of the brain that connects the spinal cord to the cerebrum and cerebellum, and controls vital functions such as breathing, heart rate, and blood pressure. Decreased levels of GABA in the brain stem can cause symptoms such as spasticity, rigidity, or tremors.

Choice C reason: Decreased levels of neurotransmitters in the pons and medulla is not the best explanation because it is a condition that affects the coordination of movements, not the perception of sensory stimuli. Neurotransmitters are chemical messengers that transmit signals between nerve cells. The pons and the medulla are parts of the brain stem that are involved in the control of voluntary and involuntary movements, such as chewing, swallowing, coughing, sneezing, and blinking. Decreased levels of neurotransmitters in the pons and the medulla can cause symptoms such as ataxia, dysarthria, dysphagia, or nystagmus.

Choice D reason: Edema and necrosis of the parietal lobe neurons is the best explanation because it is a condition that affects the processing of sensory stimuli, such as touch, pain, temperature, and position. The parietal lobe is the part of the cerebrum that is responsible for integrating and interpreting sensory information from different parts of the body. The parietal lobe is divided into two hemispheres, each corresponding to the opposite side of the body. A left-sided intracerebral hemorrhage is a condition where a blood vessel in the left parietal lobe ruptures, causing bleeding and swelling in the brain tissue. This can damage the neurons, which are the nerve cells that communicate with each other and form the basis of the nervous system. Edema and necrosis of the parietal lobe neurons can cause symptoms such as loss of sensation, neglect, or agnosia on the right side of the body.
