Nursing Elites

1. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

2. What are three major causes of atherosclerosis?

• A. Hyperthyroidism, underweight, and poor appetite
• B. High blood cholesterol, high blood pressure, and cigarette smoking
• C. Constipation, peptic ulcer disease, and pancreatitis
• D. Kidney failure, edema, and sodium retention

Correct answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

3. The nurse counsels a client diagnosed with iron deficiency anemia. The nurse determines that teaching is effective if the client selects which of the following menus?

• A. Roast beef, brown rice, green beans, carrot and raisin salad, and milk
• B. Cheese pizza, tossed green salad, oatmeal-raisin cookie, and lemonade
• C. Two scrambled eggs, bacon, white toast with strawberry jam, and coffee
• D. Corn flakes with milk, whole wheat toast, and orange juice

Correct answer: A

Rationale: The correct answer is A. Roast beef is high in heme iron, which is best absorbed and helps treat iron deficiency anemia. Choices B, C, and D do not contain significant amounts of heme iron or other iron-rich foods that would be beneficial in managing iron deficiency anemia. Cheese pizza, scrambled eggs, bacon, white toast, corn flakes, and whole wheat toast do not provide the necessary heme iron needed to address the client's condition.

4. A patient with diabetes should be advised to avoid which type of carbohydrate?

• A. Simple carbohydrates
• B. Complex carbohydrates
• C. Fiber-rich carbohydrates
• D. All carbohydrates

Correct answer: A

Rationale: A patient with diabetes should be advised to avoid simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels due to their quick absorption, which can be challenging to manage for individuals with diabetes. Complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes as they are absorbed more slowly, leading to more stable blood glucose levels. Avoiding all carbohydrates is not necessary or recommended, as carbohydrates are an essential source of energy and nutrients in a balanced diet.

5. The nurse administers 2 units of salt-poor albumin to a client with portal hypertension and ascites. The nurse explains to the client that this is administered to:

• A. Provide nutrients
• B. Increase protein stores
• C. Elevate the circulating blood volume
• D. Divert blood flow away from the liver temporarily

Correct answer: C

Rationale: The correct answer is C: Elevate the circulating blood volume. Albumin increases the circulating blood volume, which helps to reduce ascites and improve hemodynamics in clients with portal hypertension. Choice A is incorrect because salt-poor albumin is not primarily administered to provide nutrients. Choice B is incorrect because the main purpose of administering albumin is not to increase protein stores but to address fluid shifts. Choice D is incorrect because administering albumin does not divert blood flow away from the liver temporarily; instead, it helps improve blood volume and circulation.
