The nurse is monitoring a client taking Lasix (furosemide). Which of the following findings would prompt the nurse to notify the health care provider?
Serum potassium level of 5.5 mEq/L
Blood pressure of 130/80 mmHg
Serum potassium level of 3.0 mEq/L
Serum sodium level of 140 mEq/L
The Correct Answer is C
Choice A reason: Serum potassium level of 5.5 mEq/L is above the normal range of 3.55.0 mEq/L, but it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should monitor the serum potassium level and administer potassium supplements or potassium sparing diuretics as prescribed to prevent hypokalemia.
Choice B reason: Blood pressure of 130/80 mmHg is slightly above the normal range of 120/80 mmHg, but it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can reduce the fluid volume and the peripheral resistance, which can lower the blood pressure and prevent or treat hypertension, edema, or heart failure. The nurse should monitor the blood pressure regularly and adjust the dose of Lasix as prescribed to maintain a normal blood pressure.
Choice C reason: Serum potassium level of 3.0 mEq/L is below the normal range of 3.55.0 mEq/L, and it is a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should notify the health care provider immediately and prepare to administer interventions such as potassium supplements or potassium sparing diuretics to correct hypokalemia.
Choice D reason: Serum sodium level of 140 mEq/L is within the normal range of 135145 mEq/L, and it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can cause the loss of sodium in the urine, which can lead to hyponatremia, a condition that causes confusion, seizures, coma, or death. The nurse should monitor the serum sodium level and administer sodium supplements or fluids as prescribed to prevent hyponatremia.

Correct Answer is ["B","C"]
Explanation
Choice A reason: This is incorrect. Polydipsia is excessive thirst, which is a symptom of hyperglycemia (high blood sugar), not hypoglycemia (low blood sugar). People with hyperglycemia lose fluid through frequent urination and become dehydrated, which makes them thirsty.
Choice B reason: This is correct. Shaking is a common sign of hypoglycemia. It occurs because the body releases adrenaline and other hormones to raise blood sugar levels. Adrenaline causes the muscles to tremble or shake.
Choice C reason: This is correct. Confusion is another common sign of hypoglycemia. It occurs because the brain does not get enough glucose, which is its main source of energy. Low blood sugar can impair cognitive functions, such as memory, attention, and judgment.
Choice D reason: This is incorrect. Tachycardia is a rapid heart rate, which can be a symptom of both hypoglycemia and hyperglycemia. However, it is not a specific or reliable indicator of low blood sugar, as it can also be caused by other factors, such as stress, anxiety, caffeine, or medication.
Choice E reason: This is incorrect. Polyuria is excessive urination, which is another symptom of hyperglycemia, not hypoglycemia. People with hyperglycemia have high levels of glucose in their blood, which draws water from the cells and increases urine output.
Correct Answer is A
Explanation
Choice A reason: This is correct. Constipation is a common side effect of aluminum hydroxide, as it reduces the motility of the gastrointestinal tract. The nurse should advise the client to report this symptom and to increase their fluid and fiber intake to prevent it.
Choice B reason: This is incorrect. Flatulence is not a common side effect of aluminum hydroxide. It may be caused by other factors, such as diet, swallowing air, or bacterial overgrowth in the intestines.
Choice C reason: This is incorrect. Headache is not a common side effect of aluminum hydroxide. It may be caused by other factors, such as stress, dehydration, or caffeine withdrawal.
Choice D reason: This is incorrect. Palpitations are not a common side effect of aluminum hydroxide. They may be caused by other factors, such as anxiety, heart problems, or medication interactions.
