A nurse is caring for a client who is taking digoxin 0.125 mg PO daily and is at risk for
developing digoxin toxicity. The nurse should monitor the client for an imbalance of which of the following electrolytes because it can increase the risk for digoxin toxicity?
Calcium
Magnesium
Phosphatase
Potassium
The Correct Answer is D
A low potassium level (hypokalemia) can increase the risk for digoxin toxicity because it enhances the binding of digoxin to cardiac cells and increases its effects on cardiac contractility and electrical conduction. The nurse should monitor the client's potassium level and administer potassium supplements as prescribed if needed. The other electrolytes are not directly related to digoxin toxicity.

Explanation
An ileostomy is a surgical opening in the abdomen that connects the end of the small intestine (ileum) to a pouch or bag on the outside of the body. The ileostomy bypasses the large intestine (colon) and rectum, which normally absorb water and form solid stools. Therefore, the client should expect their stools to be loose and watery. The client should empty their bag several times a day, not when it is full, to prevent leakage and skin irritation. The client should avoid laxatives, which can cause dehydration and electrolyte imbalance. The client should also avoid high-fiber foods, which can cause blockage or irritation of the ileostomy.
Correct Answer is A
Explanation
Clostridium difficile is a spore-forming bacteria that can cause severe diarrhea and other gastrointestinal symptoms. It's highly contagious and can easily spread to other patients.Alcohol-based hand rubs are not effective against spores and should not be used for hand hygiene in this case. Chlorhexidine is also not sporicidal and should not be used for environmental cleaning. A protective environment is indicated for clients who are at risk of infection from others, not for clients who are infectious to others.Gloves are important for preventing the spread of infection, but they should be used in conjunction with other infection control measures, such as handwashing and protective isolation.
