Correct Answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.

Correct Answer: A

Rationale: Administering pain medication before changing the dressing is the priority action as it will help alleviate the client's pain and improve comfort. Choice B, changing the dressing less frequently, may hinder proper wound care and healing. Applying a topical anesthetic (choice C) might offer some relief but systemic pain medication is more effective. Using a non-adherent dressing (choice D) can reduce pain during dressing changes, but addressing immediate pain with medication is the most appropriate intervention in this case.

Correct Answer: D

Rationale: In the event of accidental poisoning, it is crucial to know the child's age and weight to determine the appropriate treatment. This information helps healthcare providers calculate the correct dosage of antidotes or medications needed based on the child's size and age. The child's age and weight play a significant role in managing accidental poisoning cases. Therefore, this information should be a priority for parents to communicate in such emergencies. Choices A, B, and C are not as critical as the child's age and weight when it comes to immediate treatment decisions for accidental poisoning.

Correct Answer: C

Rationale: The nurse most likely observed plantar warts, which appear on the sole of the foot and are caused by the papillomavirus. Corns (Choice A) and calluses (Choice B) are areas of thickened skin caused by pressure or friction and are not typically associated with viruses. Athlete's foot (Choice D) is a fungal infection that usually affects the skin between the toes and is not caused by a virus like plantar warts.

Correct Answer: D

Rationale: The correct answer is D. When performing fecal occult blood testing, it is crucial to inform the client that the specimen must not be contaminated with urine to prevent false results. Choices A and B are incorrect because eating more protein is not required before testing, and multiple stool specimens may be necessary for accurate results, respectively. Additionally, regarding choice C, a red color change, not blue, indicates a positive test result, making it an incorrect option.
