A nurse is providing instruction to a new nurse about caring for clients who are receiving diuretic therapy to treat heart failure. The nurse should explain that which of the following medications puts clients at risk for both hyperkalemia and hyponatremia?

A. You should advance your weak leg forward to the cane, then move your strong leg:
Advancing the weak leg first and then the strong leg is not the proper technique for using a cane. The correct method is to hold the cane on the stronger side and move the cane and the weaker leg forward together, followed by the stronger leg.

B. You should advance the cane 12 to 14 inches before taking a step:
Advancing the cane 12 to 14 inches is too far. The cane should be advanced approximately 6 to 10 inches to maintain balance and support.

C. The cane’s height should be the same as the distance from the floor to the crest of your hip bone:
The correct height for a cane is when the handle is at the level of the wrist when the user is standing with the arm hanging naturally at their side. This typically corresponds to the distance from the floor to the greater trochanter (hip bone). This ensures the cane provides the right amount of support and reduces the risk of strain or imbalance.

D. You should hold the cane in your weak hand when ambulating:
The cane should be held in the stronger hand, not the weak hand. This allows the cane to provide support to the weaker side of the body and helps to balance the weight distribution more effectively.

A) Flushed skin: Flushed skin is not typically associated with hyponatremia. Instead, hyponatremia may present with symptoms such as pallor or cool, clammy skin due to alterations in perfusion and fluid balance.

B) Fever: Fever is not a common manifestation of hyponatremia. Elevated body temperature is typically associated with conditions such as infection or inflammation rather than electrolyte imbalances like hyponatremia.

C) Nausea and vomiting: Hyponatremia, defined as a serum sodium level below 135 mEq/L, can lead to neurological symptoms, including nausea and vomiting. These symptoms occur due to alterations in osmotic pressure and cellular swelling resulting from the relative excess of water compared to sodium in the extracellular fluid. Other neurological symptoms of hyponatremia can include headache, confusion, lethargy, and seizures.

D) Extreme thirst: Extreme thirst, or polydipsia, is more commonly associated with hypernatremia, which is characterized by a serum sodium level above 145 mEq/L. Hypernatremia results from dehydration or a deficit of body water relative to sodium, leading to increased thirst as the body attempts to restore fluid balance.
