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 who took a camping vacation two weeks ago in a country with a tropical climate comes to the clinic describing vague symptoms and diarrhea for the past week. Which finding is most important for the nurse to report to the HCP?

• A. Weakness and fatigue
• B. Intestinal cramping
• C. Weight loss
• D. Jaundiced sclera

Correct answer: D

Rationale: The most important finding to report to the healthcare provider is a jaundiced sclera. Jaundice suggests liver involvement, which can be a sign of a serious underlying condition. Weakness and fatigue, intestinal cramping, and weight loss are important symptoms, but jaundice indicates a more urgent issue that needs immediate attention.

3. The nurse is teaching a client with gastroesophageal reflux disease (GERD) about dietary modifications. Which food should the client avoid?

• A. Applesauce
• B. White rice
• C. Coffee
• D. Bananas

Correct answer: C

Rationale: The correct answer is C: Coffee. Coffee should be avoided by clients with GERD as it can relax the lower esophageal sphincter, leading to an increase in GERD symptoms. Choices A, B, and D are not directly associated with worsening GERD symptoms and can be included in moderation in the diet of a client with GERD.

4. The nurse instructs the mother of a child with a ventricular septal defect that she can expect the child to become cyanotic when the child does what?

• A. Experiences an elevation in temperature.
• B. Sleeps on the left side.
• C. Cries vigorously.
• D. Eats.

Correct answer: C

Rationale: The correct answer is C: Cries vigorously. When the child cries vigorously, it increases the pressure in the right ventricle, allowing unoxygenated blood to enter the circulating volume, leading to cyanosis. This occurs due to the shunting of blood from the right side of the heart to the left side through the ventricular septal defect. Choices A, B, and D are incorrect because they do not directly impact the pressure in the right ventricle, which is crucial in causing cyanosis in this scenario.

5. In a disaster area, a nurse assesses an adult male with partial-thickness burns on his lower legs, approximately 10% of his lower body. Which color of triage tag should the nurse place on this client?

• A. Yellow.
• B. Black.
• C. Red.
• D. Green.

Correct answer: A

Rationale: A yellow triage tag should be placed on the client with partial-thickness burns covering 10% of his lower body. Yellow tags indicate delayed treatment, suitable for serious injuries that are not immediately life-threatening. Black tags are used for deceased individuals, red tags for immediate treatment of life-threatening injuries, and green tags for minor injuries.
