The antagonistic agent to digoxin toxicity is what?
Protamine sulfate.
Acetylcysteine.
Antidigoxin.
Activated charcoal.
The Correct Answer is C
Antidigoxin is an antidote for digoxin toxicity that binds and inactivates digoxin, a cardiac glycoside that can cause life-threatening arrhythmias, hyperkalemia, and other symptoms when overdosed. Antidigoxin is also known as digoxin immune Fab or DIGIFab.
Choice A, protamine sulfate, is wrong because it is an antidote for heparin, an anticoagulant that can cause bleeding when overdosed.
Choice B, acetylcysteine, is wrong because it is an antidote for acetaminophen, a painkiller that can cause liver damage when overdosed.
Choice D, activated charcoal, is wrong because it is a nonspecific adsorbent that can reduce the absorption of some drugs or poisons from the gastrointestinal tract, but it is not effective for digoxin toxicity.

Correct Answer is B
Explanation
The nurse should contact the provider before administering furosemide because the patient has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Furosemide is a diuretic that can cause potassium loss and worsen hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and fatigue. The nurse should also monitor the patient’s blood pressure, weight, and urine output, as furosemide can lower blood pressure and cause dehydration.
Choice A. Administer medication is wrong because the nurse should not give furosemide without checking with the provider first, as it could be harmful to the patient with low potassium.
Choice C. Hold medication is wrong because the nurse should not withhold furosemide without a valid reason or an order from the provider, as it could cause fluid overload and worsen the patient’s condition.
Choice D. Give potassium supplement is wrong because the nurse should not give potassium supplement without an order from the provider, as it could cause hyperkalemia or interact with other medications.
Correct Answer is B
Explanation
HDL stands for high-density lipoprotein, which is a type of cholesterol that carries excess cholesterol from other parts of the body back to the liver, where it can be removed.HDL cholesterol is often called the “good” cholesterol because it helps protect against heart disease by lowering the amount of plaque buildup in the arteries.Increasing HDL cholesterol levels can reduce the risk of cardiovascular disease in patients.
Choice A is wrong because increasing LDL cholesterol levels would have the opposite effect.
LDL stands for low-density lipoprotein, which is a type of cholesterol that carries cholesterol from the liver to other parts of the body, where it can accumulate in the walls of the arteries and form plaque.
LDL cholesterol is often called the “bad” cholesterol because it increases the risk of heart disease by narrowing and hardening the arteries.Decreasing LDL cholesterol levels can reduce the risk of cardiovascular disease in patients.
Choice C is wrong because increasing triglyceride levels would also increase the risk of cardiovascular disease.
Triglycerides are a type of fat (lipid) that circulates in the blood and provides energy for the body.
However, when triglycerides are too high, they can contribute to plaque formation in the arteries and inflammation of the pancreas.
High triglycerides are often associated with obesity, diabetes, metabolic syndrome, and low thyroid levels.Lowering triglyceride levels can reduce the risk of cardiovascular disease in patients.
Choice D is wrong because increasing intake of saturated fats would also increase the risk of cardiovascular disease.
Saturated fats are a type of fat that are solid at room temperature and are found mostly in animal products, such as meat, butter, cheese, and cream.
Saturated fats can raise both LDL and HDL cholesterol levels, but they also increase inflammation and oxidative stress in the body, which can damage the blood vessels and increase the risk of heart disease.Reducing intake of saturated fats and replacing them with unsaturated fats, such as olive oil, nuts, seeds, and fish, can reduce the risk of cardiovascular disease in patients.
The normal ranges for blood lipid levels are as follows:
• Total cholesterol: less than 200 mg/dL (5.2 mmol/L)
• LDL cholesterol: less than 100 mg/dL (2.6 mmol/L)
• HDL cholesterol: 40 mg/dL (1.0 mmol/L) or higher for men; 50 mg/dL (1.3 mmol/L) or higher for women
• Triglycerides: less than 150 mg/dL (1.7 mmol/L)
