A client is taking furosemide (Lasix) for management of mild hypertension. The nurse knows to assess laboratory results for a side effect of this diuretic. Select the lab value that matches a common side effect of this medication.
A serum potassium level of 5.6 mEq/L
A serum sodium level of 142 mEq/L
A serum sodium level of 138 mEq/L
A serum potassium level of 2.8 mEq/L
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice A reason: This statement is false. 3% Sodium Chloride is a hypertonic solution that can cause fluid overload, hypernatremia, and cellular dehydration. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.
Choice B reason: This statement is false. Dextrose 10% in water is a hypotonic solution that can cause fluid shifts, hyponatremia, and cellular edema. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.
Choice C reason: This statement is true. 0.9% Sodium Chloride with 40 mEq Potassium (KCl) is an isotonic solution that can maintain fluid and electrolyte balance. It is indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses, especially sodium and potassium.
Choice D reason: This statement is false. Lactated Ringers is an isotonic solution that can maintain fluid and electrolyte balance, but it also contains lactate, which can be converted to bicarbonate in the liver. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who may have metabolic acidosis due to diarrhea and lactate accumulation.
Correct Answer is A
Explanation
Choice A reason: This statement is true. Fluid volume deficit, or hypovolemia, is a condition where the body loses more fluid than it gains. It can be caused by fluid loss from vomiting, diarrhea, bleeding, or excessive sweating. Fluid volume deficit can lead to dehydration, hypotension, tachycardia, and shock.
Choice B reason: This statement is false. Sodium imbalance, or dysnatremia, is a condition where the blood sodium level is either too high or too low. It can be caused by fluid imbalance, kidney disease, hormonal disorders, or medications. Sodium imbalance can affect the brain function, causing confusion, seizures, or coma.
Choice C reason: This statement is false. Potassium imbalance, or dyskalemia, is a condition where the blood potassium level is either too high or too low. It can be caused by kidney disease, acid-base disorders, medications, or dietary intake. Potassium imbalance can affect the heart function, causing arrhythmias, cardiac arrest, or death.
Choice D reason: This statement is false. Fluid volume excess, or hypervolemia, is a condition where the body gains more fluid than it loses. It can be caused by fluid overload, heart failure, kidney failure, or liver disease. Fluid volume excess can lead to edema, hypertension, dyspnea, and pulmonary congestion.
