The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level 10.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)) Creatinine 10.5 to 1.1 mg/dL (44 to 97 μmol/L)]

A. Sodium level of 135 mEq/L (135 mmol/L): A sodium level of 135 mEq/L is slightly below the normal reference range of 136 to 145 mEq/L. While this is a mild hyponatremia, it is not immediately life-threatening and does not usually require urgent intervention unless there are other symptoms or complications. B. Creatinine level of 0.8 mg/dL (70.77 μmol/L): A creatinine level of 0.8 mg/dL is within the normal reference range of 0.5 to 1.1 mg/dL. This value indicates normal kidney function and does not require immediate reporting. C. Potassium level of 3.2 mEq/L (3.2 mmol/L): A potassium level of 3.2 mEq/L is below the normal reference range of 3.5 to 5.0 mEq/L, indicating hypokalemia. Hypokalemia is of significant concern when a client is taking digoxin, as low potassium levels can increase the risk of digoxin toxicity and potentially lead to serious cardiac arrhythmias. D. Digoxin level of 1.1 ng/mL (1.4 nmol/L): A digoxin level of 1.1 ng/mL is within the therapeutic range of 0.6 to 2.0 ng/mL. This level does not indicate toxicity and does not need to be reported immediately.
