Correct Answer: D

Rationale: Step 1: Symptoms of food poisoning typically include salivation, cramping, nausea, vomiting, and diarrhea, so statement A is correct. Step 2: Food left unrefrigerated can lead to bacterial growth, making it more dangerous, so statement B is accurate. Step 3: Cooking can kill harmful organisms and stop the production of toxins, supporting statement C. Step 4: All three statements are true and collectively provide a comprehensive understanding of food poisoning, making option D the correct answer.

Correct Answer: B

Rationale: The correct answer is B: IgE. IgE is specific to allergic responses as it binds to mast cells and basophils, triggering the release of histamine and other inflammatory mediators. IgA is more involved in mucosal immunity, IgG is involved in long-term immunity and opsonization, and IgM is the primary antibody in the primary immune response. IgB is not a known immunoglobulin. Therefore, IgE is the specific immunoglobulin associated with allergic responses due to its role in mediating hypersensitivity reactions.

Correct Answer: A

Rationale: The correct answer is A: A normal finding. The Darwin tubercle is a small, painless, bony nodule at the helix of the ear and is considered a normal anatomical variation. It is present in a significant portion of the population, regardless of age. It does not indicate any pathology or abnormality. Choices B, C, and D are incorrect because the presence of a Darwin tubercle is not indicative of any abnormality, and it is not limited to older adults.

Correct Answer: C

Rationale: The correct answer is C: Memory cells. After recovery from a disease, memory cells are formed as part of the adaptive immune response. These memory cells "remember" the pathogen and can mount a quicker and stronger immune response upon re-exposure. This results in immunity to the disease. Antigens (choice A) are substances that trigger the immune response but do not provide immunity on their own. Complement (choice B) is a group of proteins that enhance the immune response but do not directly lead to immunity. Natural killer cells (choice D) are part of the innate immune system and are not responsible for the specific memory response needed for immunity.

Correct Answer: C

Rationale: The correct answer is C: Ineffective cerebral tissue perfusion. In the late stage of AIDS, the client is at risk for neurological complications, including AIDS-related dementia due to decreased blood flow to the brain. This nursing diagnosis takes the highest priority as it directly addresses the client's impaired brain perfusion, which can lead to serious cognitive and functional deficits. Prioritizing this diagnosis ensures timely interventions to optimize cerebral blood flow and prevent further deterioration. Summary: A: Self-care deficient: Bathing/hygiene - important but not the highest priority compared to addressing neurological complications. B: Dysfunctional grieving - while emotional support is essential, it is not the priority when dealing with a life-threatening physiological issue. D: Risk for injury - while important, it is secondary to addressing the underlying cause of the dementia in this scenario.
