Question

A nurse is caring for a client who was admitted for a treatment of left-sided heart failure with intravenous loop diuretics and digitalis therapy. the client is experiencing weakness and an irregular hear rate. which of the following actions should the nurse take first?

A- obtain clients current weight
B-Determine the time of the last digoxin dose
C- Check the clients urine output
D- Review serum electrolyte Values

Answer 1

The nurse should first review serum electrolyte values since electrolyte imbalances can contribute to arrhythmias and affect heart rate, especially in a patient on loop diuretics and digitalis therapy.

Step-by-step explanation:

The first action a nurse should take when caring for a client who has left-sided heart failure and is experiencing weakness and an irregular heart rate after intravenous loop diuretics and digitalis therapy is to review serum electrolyte values. This is critical because electrolyte imbalances, particularly of sodium and potassium, can contribute to arrhythmias and other cardiac issues. Loop diuretics inhibit the reabsorption of sodium and chloride ions by the ascending limb of the loop of Henle, leading to increased urination and the potential for electrolyte depletion. Digitalis, or digoxin, can be affected by these electrolyte levels, further influencing the heart's rhythm. Thus, checking the serum electrolyte values can address the immediate concern for cardiac complications and guide further treatment.
