A nurse is caring for a client who is taking furosemide (Lasix) daily to treat heart failure. The nurse recognizes that the client is at risk for which electrolyte imbalance?
Hypokalemia
Hypocalcemia
Hypernatremia
Hyperkalemia
The Correct Answer is A
A. Hypokalemia: Furosemide is a loop diuretic that works by increasing urinary excretion of sodium, chloride, and water, which can lead to potassium loss. Hypokalemia is a common electrolyte imbalance associated with the use of loop diuretics like furosemide. Potassium depletion can cause various complications, including cardiac dysrhythmias, muscle weakness, and fatigue.
B. Hypocalcemia: Furosemide does not directly affect calcium levels, so hypocalcemia is not a common electrolyte imbalance associated with its use.
C. Hypernatremia: Furosemide promotes the excretion of sodium, so hypernatremia (elevated serum sodium levels) is not typically a concern with its use.
D. Hyperkalemia: Furosemide can cause potassium loss, so hyperkalemia is not a risk associated with its use.

Correct Answer is D
Explanation
A. Freshly squeezed orange juice: Orange juice is generally not considered a trigger for gout attacks. However, it is high in fructose, which may contribute to gout if consumed excessively.
B. Milk: Milk is not typically associated with triggering gout attacks and is often recommended as part of a healthy diet for gout.
C. Black Coffee: Coffee, especially black coffee, is generally considered safe for individuals with gout and may even have some protective effects against gout attacks.
D. Sweetened iced tea: Sweetened iced tea is often made with high-fructose corn syrup, which can increase uric acid levels and potentially trigger gout attacks. Therefore, it is important for individuals with gout to limit their intake of sweetened beverages like iced tea.
Correct Answer is B
Explanation
A. Heart rate of 90 bpm: While an elevated heart rate may be expected in response to burn injury and the body's stress response, a heart rate of 90 bpm alone may not be concerning without additional context.
B. Blood pressure of 96/50 mm Hg: This blood pressure reading indicates hypotension, which can be a sign of inadequate tissue perfusion, fluid loss, or shock. It requires prompt notification of the healthcare provider for further assessment and intervention.
C. Urine output of 2 mL/kg per hour: Adequate urine output is important for renal function and fluid balance, and a urine output of 2 mL/kg per hour is within the normal range. While changes in urine output should be monitored, this finding alone does not require immediate notification of the healthcare provider.
D. Pain rating of 7 on a 1 to 10 point scale: Pain management is important in burn care, but a pain rating of 7 on a 1 to 10 scale is not unusual in clients with burns and may not require immediate notification of the healthcare provider unless accompanied by other concerning symptoms.
