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. In formulating an objective of a community care plan, she expected results and people taking part in the activities should be clearly defined. This refers to an objective which is:
- A. time-bound
- B. specific
- C. resource-oriented
- D. measurable
Correct answer: B
Rationale: The correct answer is 'specific.' In formulating a community care plan, defining expected results and participant roles require objectives to be specific to provide clear guidance and outcomes. 'Time-bound' refers to setting deadlines, 'resource-oriented' focuses on utilizing available resources efficiently, and 'measurable' indicates the ability to quantify progress, but these aspects do not necessarily address the need for clarity and definition in defining expected results and participant roles.
3. When teaching an adolescent with type 1 diabetes about dietary management, what should the nurse include?
- A. Eating meals at home is recommended.
- B. Food portions should be measured using a gram scale.
- C. Ensure a ready source of glucose is available.
- D. No specific foods need to be cooked for the adolescent.
Correct answer: C
Rationale: When teaching an adolescent with type 1 diabetes about dietary management, it is crucial to ensure a ready source of glucose is available. In cases of hypoglycemia, having a quick source of glucose can help raise blood sugar levels rapidly. Option A is not the most critical aspect of dietary management for an adolescent with type 1 diabetes. While it is generally recommended to eat meals at home for better control over food choices, the availability of a ready glucose source takes precedence. Option B, weighing foods on a gram scale, may not be practical for every meal and could be burdensome. Option D, cooking specific foods for the adolescent, is not necessary as the focus should be on the overall dietary plan rather than individualized meals.
4. The nurse is caring for a client with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?
- A. Administer morphine for pain relief.
- B. Encourage the client to perform isometric exercises.
- C. Position the client flat in bed.
- D. Restrict fluid intake.
Correct answer: A
Rationale: Administering morphine is a priority intervention during the acute phase of myocardial infarction (MI). Morphine not only provides pain relief but also reduces myocardial oxygen demand, which is crucial in this situation. Choice B is incorrect because isometric exercises can increase myocardial oxygen demand and are not recommended during the acute phase of MI. Choice C is incorrect as elevating the head of the bed, not keeping the client flat, is preferred to reduce workload on the heart. Choice D is incorrect because fluid intake should be encouraged unless contraindicated, as adequate hydration is essential for cardiac function.
5. A nurse is providing discharge teaching to the parent of a toddler who has a new diagnosis of asthma. The parent states she is unable to afford the nebulizer prescribed for the child. Which of the following referrals should the nurse recommend?
- A. Social worker
- B. Pharmacist
- C. Respiratory therapist
- D. Child protective services
Correct answer: A
Rationale: The correct answer is A: Social worker. A social worker can assist the parent in finding resources to afford the nebulizer. While a pharmacist may provide information about medications and devices, they may not have direct resources to address financial concerns. A respiratory therapist focuses on respiratory care but may not specialize in financial assistance. Referring to child protective services is not appropriate in this scenario as the parent's inability to afford a nebulizer does not indicate neglect or abuse.
