The nurse should explain that which of the following medications puts a client at risk for developing hyperkalemia?

Furosemide (Lasix)

Spironolactone (Aldactone)

Sodium polystyrene sulfate (Kayexalate)

Insulin

Answer and Explanation

The Correct Answer is B

A. Furosemide (Lasix) is a loop diuretic that typically causes the loss of potassium through the urine, thus putting clients at risk for hypokalemia, not hyperkalemia.
B. Spironolactone (Aldactone) is a potassium-sparing diuretic, meaning it helps the body retain potassium. As a result, it can lead to hyperkalemia, especially in patients with kidney dysfunction or when used with other medications that increase potassium levels.
C. Sodium polystyrene sulfate (Kayexalate) is used to treat hyperkalemia by exchanging sodium for potassium in the intestines, thus lowering potassium levels. It does not contribute to hyperkalemia.
D. Insulin does not directly cause hyperkalemia; in fact, insulin administration can lower potassium levels by driving potassium into cells.

Correct Answer is A

Explanation

A. Encouraging a low-sodium diet is inappropriate for a client with hyponatremia. Hyponatremia is a condition of low sodium levels in the blood, and the priority in managing this condition is to restore normal sodium levels, not to restrict sodium.
B. Padding the side rails of the bed is appropriate to protect the client from injury, especially if the client is at risk for seizures due to the electrolyte imbalance.
C. Providing a quiet and calm environment is beneficial for a client with hyponatremia, as it can help reduce the risk of seizures or agitation associated with the condition.
D. Having the client use the call light when toileting is needed is a standard precaution to ensure the client’s safety, especially if they are at risk of falls or confusion due to the electrolyte imbalance.

A. Advise the client to add citrus juices and bananas to their diet. B. Obtain a 12-lead ECG. C. Obtain a blood sample for a serum sodium level. D. Suggest that the client use a salt substitute.

Correct Answer is B

Explanation

A. Advising the client to add citrus juices and bananas is inappropriate because these are high in potassium and would further increase the already elevated potassium level, potentially worsening hyperkalemia.
B. Obtaining a 12-lead ECG is the correct action. A potassium level of 6.8 mEq/L is critically high and can cause life-threatening cardiac arrhythmias. An ECG can help identify hyperkalemia-related changes, such as peaked T waves, widened QRS complexes, or arrhythmias.
C. While obtaining a serum sodium level might provide additional information, it does not address the immediate risk posed by the elevated potassium level. The priority is assessing the cardiac effects of hyperkalemia.
D. Suggesting that the client use a salt substitute is incorrect, as many salt substitutes contain potassium chloride, which could worsen hyperkalemia.
