Anu is reinforcing teaching with a client who is starting simvastatin.
Which of the following information should the nurse include?
Change position slowly when rising from a chair.
Maintain a steady intake of green leafy vegetables.
Consume no more than 1 L/day of fluid.
Take this medication in the evening.
The Correct Answer is D
Simvastatin is a type of drug called a statin, which lowers cholesterol and triglycerides in the blood. Statins work by reducing the amount of cholesterol made by the liver, and the liver produces more cholesterol at night. Therefore, taking simvastatin in the evening can increase its effectiveness.
Choice A is wrong because changing position slowly when rising from a chair is not related to simvastatin use.
This advice is usually given to people who have low blood pressure or take medications that lower blood pressure, such as diuretics or beta blockers.
Choice B is wrong because maintaining a steady intake of green leafy vegetables is not specific to simvastatin use.
This advice is usually given to people who take anticoagulants, such as warfarin, because green leafy vegetables contain vitamin K, which can affect the blood clotting process.
Choice C is wrong because consuming no more than 1 L/day of fluid is not related to simvastatin use.
This advice is usually given to people who have fluid retention or heart failure, because excess fluid can put strain on the heart and lungs.

Correct Answer is D
Explanation
HDL stands for high-density lipoprotein, which is a type of cholesterol that carries excess cholesterol from other parts of the body to the liver, where it can be removed.
HDL is sometimes called “good” cholesterol because it helps protect against heart disease.Having high HDL levels is not a characteristic of metabolic syndrome, but rather a protective factor.
Metabolic syndrome is a group of conditions that increase the risk of heart disease, stroke, and type 2 diabetes.These conditions include:
• Low HDLs (choice A): Having low levels of HDL cholesterol is a risk factor for metabolic syndrome, as it means there is less “good” cholesterol to remove excess cholesterol from the blood vessels.
• Type II diabetes mellitus (choice B): This is a condition where the body does not use insulin properly, leading to high blood sugar levels.
Insulin is a hormone that helps the cells take up glucose from the blood.
Insulin resistance is a key feature of metabolic syndrome.
• Hypertension (choice C): This means having high blood pressure, which can damage the heart and blood vessels over time.
High blood pressure is often associated with obesity and insulin resistance, which are common in metabolic syndrome.
• Abdominal obesity (choice E): This means having excess fat around the waist and trunk, also known as central or visceral obesity.
This type of fat is more harmful than fat in other parts of the body, as it can release inflammatory substances that affect the metabolism and increase the risk of cardiovascular disease.
• Hyperglycemia (choice F): This means having high blood sugar levels, which can damage the blood vessels and organs over time.
Hyperglycemia can result from insulin resistance or type 2 diabetes, which are both components of metabolic syndrome.
The normal ranges for some of these conditions are:
• HDL cholesterol: more than 40 mg/dL for men and more than 50 mg/dL for women
• Blood pressure: less than 120/80 mmHg
• Blood sugar: less than 100 mg/dL after fasting or less than 140 mg/dL two hours after eating
• Waist circumference: less than 40 inches for men and less than 35 inches for women
Correct Answer is A
Explanation
This is because low potassium levels (hypokalemia) increase the sensitivity of the heart to digoxin and can lead to toxicity even with normal serum digoxin levels. Digoxin inhibits the sodium-potassium pump on the cardiac cells, which causes potassium to accumulate outside the cells.Low potassium levels in the blood create a larger gradient for potassium to move out of the cells, which enhances the effect of digoxin and can cause arrhythmias.
Choice B is wrong because calcium 9.2 mg/dL is within the normal range (8.5 to 10.2 mg/dL) and does not increase the risk of digoxin toxicity.However, high calcium levels (hypercalcemia) can potentiate the effects of digoxin and cause toxicity.
Choice C is wrong because sodium 140 mEq/L is within the normal range (135 to 145 mEq/L) and does not increase the risk of digoxin toxicity.However, high sodium levels (hypernatremia) can reduce the binding of digoxin to the sodium-potassium pump and decrease its efficacy.
Choice D is wrong because magnesium 2.2 mg/dL is within the normal range (1.7 to 2.4 mg/dL) and does not increase the risk of digoxin toxicity.However, low magnesium levels (hypomagnesemia) can increase the sensitivity of the heart to digoxin and cause toxicity.
