A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L. The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Have the laboratory draw a blood sample for an erythrocyte sedimentation rate
Obtain a 12-lead ECG
Administer potassium gluconate 40 mEq orally
Restrict fluid intake
The Correct Answer is B
Choice A reason : An erythrocyte sedimentation rate (ESR) test is not directly related to high serum potassium levels and would not be the immediate action in response to hyperkalemia.
Choice B reason : Obtaining a 12-lead ECG is a critical step when hyperkalemia is suspected because high potassium levels can cause life-threatening cardiac arrhythmias. An ECG can quickly reveal characteristic changes associated with hyperkalemia, allowing for prompt treatment.
Choice C reason : Administering potassium gluconate would be contraindicated in a patient with hyperkalemia, as it would further increase the serum potassium levels, potentially leading to severe complications.
Choice D reason : Restricting fluid intake is not a standard treatment for hyperkalemia. The management of hyperkalemia may include medications or procedures that promote the excretion of potassium or move potassium from the blood into the cells.

Correct Answer is C
Explanation
Choice A reason : The statement that warfarin dissolves clots in the bloodstream is incorrect. Warfarin does not dissolve existing clots. Instead, it is an anticoagulant that works by decreasing the production of certain clotting factors in the blood, which helps prevent the formation of new clots.
Choice B reason : This statement is not accurate regarding the action of warfarin. Warfarin does not affect the electrical impulses of the heart. Medications that slow the response of the ventricles to fast atrial impulses are typically antiarrhythmic drugs, not anticoagulants like warfarin.
Choice C reason : This is the correct statement. Warfarin is prescribed for clients with atrial fibrillation to reduce the risk of stroke. Atrial fibrillation increases the risk of forming blood clots in the heart, which can then travel to the brain, causing a stroke. Warfarin's anticoagulant effect helps to prevent these clots from forming.
Choice D reason : Warfarin does not help maintain a normal heart rhythm. It is not an antiarrhythmic drug but an anticoagulant. The purpose of warfarin in atrial fibrillation is to prevent stroke by reducing the risk of clot formation, not to correct the heart rhythm.
