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. The nurse is administering a beta blocker to the client diagnosed with essential hypertension. Which data would cause the nurse to question administering the medication?

• A. The client’s BP is 110/70
• B. The client’s potassium level is 3.4 mEq/L
• C. The client has a barky cough
• D. The client’s apical pulse is 56

Correct answer: D

Rationale: The correct answer is D. A beta blocker should be withheld if the apical pulse is below 60, as it can further decrease the heart rate. Choice A is not a reason to question administering a beta blocker as the blood pressure is within normal range. Choice B is not directly related to the administration of a beta blocker. Choice C may indicate a potential adverse effect of another medication, but it does not specifically warrant questioning the administration of the beta blocker.

3. The nurse is planning to provide education about foods containing thiamine to a group of clients. Which food high in thiamine should the nurse include?

• A. Fish
• B. Pork
• C. Beef
• D. Eggs

Correct answer: B

Rationale: The correct answer is B: Pork. Pork is high in thiamine, which is important for preventing thiamine deficiency. Thiamine, also known as vitamin B1, is essential for the proper functioning of the nervous system and metabolism. While fish, beef, and eggs are nutritious foods, they are not as high in thiamine as pork. Fish is more commonly known for its omega-3 fatty acids, beef for its iron content, and eggs for being a good source of protein and other nutrients.

4. In patients with heart failure, which type of diet is most recommended?

• A. High-sodium
• B. Low-sodium
• C. High-fat
• D. Low-carbohydrate

Correct answer: B

Rationale: A low-sodium diet is most recommended for patients with heart failure. This type of diet helps manage fluid retention by reducing the amount of sodium in the body, which in turn decreases the workload on the heart. High-sodium diets can lead to fluid retention and worsen heart failure symptoms. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients as the focus is primarily on controlling sodium intake.

5. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.
