The nurse is caring for a client receiving morphine through a Patient Controlled Analgesia Pump (PCA Pump). The nurse knows that important considerations for this treatment include: SELECT ALL THAT APPLY

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: 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.
