The nurse is administering Kayexalate to a client. The nurse explains that this medication will:

Choice A reason: This statement is false. Nephropathy is a term that refers to any disease or damage of the kidneys. Acetaminophen overdose can cause nephropathy, but it is not the most serious toxic effect. Nephropathy can manifest as reduced urine output, increased blood urea nitrogen and creatinine levels, and electrolyte imbalance.

Choice B reason: This statement is false. Tachycardia is a term that refers to a fast heart rate, usually more than 100 beats per minute. Acetaminophen overdose can cause tachycardia, but it is not the most serious toxic effect. Tachycardia can be a sign of dehydration, fever, pain, or anxiety.

Choice C reason: This statement is true. Liver dysfunction is the most serious toxic effect of acute acetaminophen overdose. Acetaminophen is metabolized by the liver and can produce a toxic byproduct that damages the liver cells. Liver dysfunction can manifest as jaundice, abdominal pain, nausea, vomiting, and elevated liver enzymes.

Choice D reason: This statement is false. Central nervous system depression is a term that refers to a reduced level of consciousness, alertness, and responsiveness. Acetaminophen overdose can cause central nervous system depression, but it is not the most serious toxic effect. Central nervous system depression can be a sign of hypoxia, hypoglycemia, or drug intoxication.

Choice A reason: This statement is false. Acetaminophen (Tylenol) is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as acetaminophen is a mild analgesic that works by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain. Acetaminophen is not very effective for chronic, burning leg pain, which is likely caused by diabetic neuropathy, a nerve damage condition that affects the sensation and function of the legs.

Choice B reason: This statement is true. Gabapentin (Neurontin) is the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as gabapentin is an anticonvulsant that works by modulating the activity of calcium channels, which are involved in transmitting pain signals from the nerves to the brain. Gabapentin is effective for chronic, burning leg pain, as it can reduce the intensity and frequency of neuropathic pain.

Choice C reason: This statement is false. Hydrocodone-Acetaminophen (Norco) is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as hydrocodone-acetaminophen is a combination of an opioid analgesic and a mild analgesic that works by binding to opioid receptors in the brain and spinal cord, and by inhibiting the synthesis of prostaglandins, respectively. Hydrocodone-acetaminophen is not very effective for chronic, burning leg pain, as it can cause tolerance, dependence, and addiction, and can also interact with oxycodone, which the patient is already taking.

Choice D reason: This statement is false. Aspirin is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain. Aspirin is not very effective for chronic, burning leg pain, as it can cause gastrointestinal bleeding, ulcers, and kidney damage, and can also interact with other medications that the patient may be taking, such as anticoagulants or antiplatelets.
