Nursing Elites

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. What is the most critical initial intervention for a client who is actively seizing?

• A. Restrain the client to prevent injury
• B. Insert an oral airway
• C. Turn the client to the side
• D. Apply soft restraints to the wrists

Correct answer: C

Rationale: The most critical initial intervention for a client who is actively seizing is to turn the client to the side. This action helps maintain an open airway and prevents aspiration during a seizure. Restrain the client to prevent injury (Choice A) is incorrect because restraining a client during a seizure can lead to injury. Inserting an oral airway (Choice B) is not recommended as it can cause injury and is not necessary during an active seizure. Applying soft restraints to the wrists (Choice D) is also not recommended as it can lead to harm and does not address the immediate airway management needed during a seizure.

3. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?

• A. Fresh fruits
• B. Processed cheese
• C. Whole grain bread
• D. Fresh vegetables

Correct answer: B

Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.

4. On the first postoperative day, the nurse finds an older male client disoriented and trying to climb over the bed railing. Previously, he was oriented to person, place, and time on admission. Which intervention should the nurse implement first?

• A. Administer a sedative.
• B. Determine the client’s blood pressure.
• C. Apply soft restraints.
• D. Call for assistance.

Correct answer: B

Rationale: The correct intervention the nurse should implement first is to determine the client’s blood pressure. Assessing the blood pressure is crucial in this situation to rule out physiological causes like hypotension leading to the client's disorientation. Administering a sedative (Choice A) without understanding the underlying cause may worsen the situation. Applying soft restraints (Choice C) should not be the initial action and can be considered later if necessary. Calling for assistance (Choice D) may be needed eventually, but assessing the client's blood pressure takes precedence to address the immediate concern.

5. The nurse is obtaining a client's fingerstick glucose level. After gently milking the client's finger, the nurse observes that the distal tip of the finger appears reddened and engorged. What action should the nurse take?

• A. Collect the blood sample
• B. Assess radial pulse volume
• C. Apply pressure to the site
• D. Select another finger

Correct answer: A

Rationale: When the nurse observes that the distal tip of the client's finger is reddened and engorged after milking, it indicates adequate blood flow. At this point, the appropriate action is to collect the blood sample for glucose level testing. Assessing radial pulse volume (Choice B) is unrelated to the situation and not necessary. Applying pressure to the site (Choice C) may disrupt the blood sample collection process. Selecting another finger (Choice D) is not warranted as the engorgement indicates sufficient blood flow for sampling.
