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

Choice A reason: A serum potassium level of 5.6 mEq/L is not a common side effect of furosemide, but of hyperkalemia. Hyperkalemia is a condition where the blood potassium level is too high. It can cause muscle weakness, irregular heartbeat, and cardiac arrest. Furosemide is a loop diuretic that increases the urinary excretion of water, sodium, chloride, and potassium. It can cause hypokalemia, which is a low blood potassium level, not hyperkalemia.

Choice B reason: A serum sodium level of 142 mEq/L is not a common side effect of furosemide, but of normal sodium level. The normal range of serum sodium level is 135 to 145 mEq/L. Sodium is an electrolyte that helps regulate the fluid balance, nerve impulses, and muscle contractions in the body. Furosemide can cause hyponatremia, which is a low blood sodium level, but not a normal sodium level.

Choice C reason: A serum sodium level of 138 mEq/L is also not a common side effect of furosemide, but of normal sodium level. As explained in choice B, the normal range of serum sodium level is 135 to 145 mEq/L. Furosemide can cause hyponatremia, which is a low blood sodium level, but not a normal sodium level.

Choice D reason: A serum potassium level of 2.8 mEq/L is a common side effect of furosemide, and of hypokalemia. Hypokalemia is a condition where the blood potassium level is too low. It can cause muscle cramps, fatigue, weakness, arrhythmias, and paralysis. Furosemide is a loop diuretic that increases the urinary excretion of water, sodium, chloride, and potassium. It can cause hypokalemia, which is a low blood potassium level. The nurse should monitor the client's serum potassium level and signs of hypokalemia, and advise the client to eat potassium-rich foods, such as bananas, oranges, and potatoes. The nurse should also report the lab value to the prescriber, who may adjust the dose of furosemide or prescribe a potassium supplement.

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.
