When the nurse is reviewing a patient's daily laboratory test results, which of the following potassium levels should the nurse report to the healthcare provider to reduce the risk of digoxin (Lanoxin) toxicity?

Potassium 5.5 mEq/L

Potassium 3.8 mEq/L

Potassium 4.5 mEq/L

Potassium 2.9 mEq/L

Answer and Explanation

The Correct Answer is D

Choice A reason: A high potassium level can increase the risk of digoxin toxicity. The normal range for potassium is typically 3.5 to 5.0 mEq/L, so a level of 5.5 mEq/L should be reported.

Choice B reason: A potassium level of 3.8 mEq/L is within the normal range and would not typically increase the risk of digoxin toxicity.

Choice C reason: A potassium level of 4.5 mEq/L is within the normal range and would not typically increase the risk of digoxin toxicity.

Choice D reason: A low potassium level can also increase the risk of digoxin toxicity, but the question asks for the result that does not increase the risk, making 2.9 mEq/L incorrect in this context.

Correct Answer is A

Explanation

Choice A reason: Fresh vegetables are typically low in sodium and are a healthy choice for someone on a low-sodium diet.

Choice B reason: Canned soups often have high sodium content and are not recommended for a low-sodium diet.

Choice C reason: Hot dogs are processed meats that are usually high in sodium and should be avoided on a low-sodium diet.

Choice D reason: Milk and cheese can vary in sodium content; some cheeses are high in sodium and should be consumed in moderation or avoided. Fresh vegetables are the safest recommendation as they are naturally low in sodium and fit within a low-sodium diet.

A. Have the patient sit in his room while you review all the rules of the unit. B. Reinforce previously learned coping mechanisms to calm the patient down. C. Place the patient in a room with another hyperactive patient. D. Administer antipsychotic medication as ordered and as needed by the physician.

Correct Answer is D

Explanation

Choice A reason: Having the patient sit alone while reviewing rules does not address the immediate risk of injury due to hyperactivity.

Choice B reason: Reinforcing coping mechanisms can help the patient manage hyperactivity and reduce the risk of injury.

Choice C reason: Placing the patient with another hyperactive patient could potentially exacerbate the situation and increase the risk of injury.

Choice D reason: While administering medication may be necessary, it should be done in conjunction with other interventions that address behavior management.
