1. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

2. The client with chronic venous insufficiency is being taught about self-care measures. Which instruction should be included?

• A. Avoid wearing compression stockings
• B. Elevate legs above heart level when resting
• C. Apply heat packs to improve circulation
• D. Limit walking to prevent leg pain

Correct answer: B

Rationale: The correct instruction for a client with chronic venous insufficiency is to elevate their legs above heart level when resting. This position helps reduce venous pressure and edema, improving circulation. Avoiding compression stockings (choice A) is incorrect as they are beneficial in managing chronic venous insufficiency. Applying heat packs (choice C) is not recommended as heat can worsen edema. Limiting walking (choice D) is not advisable as regular, gentle exercise like walking can actually help improve circulation in patients with chronic venous insufficiency.

3. The nurse is providing discharge teaching for a client with heart failure. Which instruction should be included to prevent fluid overload?

• A. Weigh yourself daily and report a gain of 2 pounds in 24 hours
• B. Increase fluid intake to stay hydrated
• C. Consume a high-sodium diet to retain fluids
• D. Engage in vigorous exercise daily

Correct answer: A

Rationale: The correct answer is A: 'Weigh yourself daily and report a gain of 2 pounds in 24 hours.' Daily weight monitoring is crucial for detecting fluid retention early in clients with heart failure. Reporting a gain of 2 pounds in 24 hours can indicate fluid overload, prompting timely intervention. Choice B is incorrect because increasing fluid intake can exacerbate fluid overload in clients with heart failure. Choice C is incorrect as a high-sodium diet can worsen fluid retention. Choice D is incorrect as vigorous exercise can strain the heart and worsen heart failure symptoms.

4. Which type of lipoprotein is associated with decreasing the risk of atherosclerosis?

• A. High-density lipoprotein (HDL)
• B. Low-density lipoprotein (LDL)
• C. Very low-density lipoprotein (VLDL)
• D. Intermediate-density lipoprotein (IDL)

Correct answer: A

Rationale: The correct answer is High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps remove cholesterol from the arteries, reducing the risk of atherosclerosis. LDL (choice B) is considered 'bad' cholesterol as it can deposit cholesterol in the arteries, increasing the risk of atherosclerosis. VLDL (choice C) and IDL (choice D) are also associated with increased risk of atherosclerosis rather than decreasing it.

5. The nurse is evaluating teaching about drug therapy to treat gout. Which statement by the client demonstrates an understanding of the use of allopurinol to treat Gout?

• A. I need to take the prescribed amount of the drug to get rid of my gout.
• B. I need to take this drug every day to keep from having any flare-ups.
• C. I should take this drug when I have gout attacks to reduce symptoms.
• D. The pain and swelling can be controlled by taking this drug every day.

Correct answer: B

Rationale: Taking allopurinol every day helps to prevent gout flare-ups by reducing uric acid levels.
