A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?

A client taking furosemide for chronic hypertension.

A client taking a potassium supplement twice a day.

A client taking aluminum hydroxide for gastric upset.

A client taking chlorpropamide for type 2 diabetes mellitus.

Answer and Explanation

The Correct Answer is A

a. A client taking furosemide for chronic hypertension: Furosemide is a loop diuretic that can

lead to hypokalemia, which increases the risk of digoxin toxicity, as hypokalemia potentiates the effects of digoxin on the heart.

b. A client taking a potassium supplement twice a day: Potassium supplementation reduces the risk of digoxin toxicity, as hypokalemia is a risk factor for toxicity.

c. A client taking aluminum hydroxide for gastric upset: Aluminum hydroxide is an antacid and does not significantly affect digoxin levels.

d. A client taking chlorpropamide for type 2 diabetes mellitus: Chlorpropamide is an oral hypoglycemic agent and does not significantly affect digoxin levels.

Correct Answer is A

Explanation

a. Postictal phase: The postictal phase refers to the period following a seizure during which the individual may be drowsy, confused, or sleepy. This phase can last varying amounts of time.

b. Presence of absence seizures: Absence seizures are characterized by brief episodes of staring and altered consciousness but do not typically have a postictal phase with prolonged sleepiness.

c. Aura phase: The aura phase occurs before a seizure and involves sensory or perceptual changes that serve as a warning sign. It does not describe the postictal state.

d. Presence of automatisms: Automatisms are repetitive, non-purposeful movements that can occur during certain types of seizures but do not describe the postictal state of sleepiness.

A. Bradycardia B. Anemia C. Hypokalemia D. Neutropenia

Correct Answer is A

Explanation

a. Bradycardia: Atenolol is a beta-blocker that can slow down the heart rate, leading to

bradycardia. Monitoring the client for signs of bradycardia, such as dizziness, fatigue, or fainting, is important.

b. Anemia: Atenolol is not known to cause anemia. Monitoring for anemia is not a specific concern with this medication.

c. Hypokalemia: Atenolol is not associated with causing hypokalemia. However, beta-blockers in general may affect potassium levels indirectly.

d. Neutropenia: Atenolol is not typically associated with causing neutropenia. Monitoring for neutropenia is not a specific concern with this medication.
