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. A client is receiving intravenous potassium chloride for hypokalemia. Which action should the nurse take to prevent complications during the infusion?

• A. Administer the infusion rapidly
• B. Monitor the infusion site for signs of infiltration
• C. Use a syringe pump for the infusion
• D. Flush the IV line with normal saline before starting the infusion

Correct answer: B

Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.

3. A client with a new colostomy is concerned about odor. What is the best advice the nurse can provide?

• A. Avoid high-fiber foods
• B. Use an odor-proof pouch
• C. Decrease fluid intake
• D. Increase dairy products in the diet

Correct answer: B

Rationale: The best advice the nurse can provide to a client concerned about odor from a new colostomy is to use an odor-proof pouch. This option helps control odors effectively by containing and masking any unpleasant smells. Avoiding high-fiber foods (Choice A) is not the best advice as fiber is essential for bowel health, and decreasing fluid intake (Choice C) can lead to dehydration and other complications. Increasing dairy products in the diet (Choice D) is not directly related to controlling odors from a colostomy.

4. Based on the interpretation of this strip, what action should be implemented first?

• A. Call a code.
• B. Start CPR.
• C. Administer IV fluids.
• D. Apply oxygen.

Correct answer: A

Rationale: The correct answer is A: 'Call a code.' In the context of ventricular fibrillation (V-Fib), immediate defibrillation is crucial. Calling a code is the first step to activating the emergency response team, including individuals trained to provide defibrillation. Starting CPR (Choice B) may be necessary but should follow defibrillation. Administering IV fluids (Choice C) and applying oxygen (Choice D) are important interventions in cardiac arrest cases, but in V-Fib, the priority is defibrillation to restore normal heart rhythm.

5. What is the hallmark sign of intussusception?

• A. Mucus-like stools
• B. Currant jelly-like stools
• C. Tarry, black stools
• D. Green, soft stools

Correct answer: B

Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.
