Correct Answer: B

Rationale: Step 1: TIS stands for carcinoma in situ, which means cancer cells are present only in the layer of cells where they first developed. Step 2: N0 indicates no abnormal regional lymph nodes are involved. Step 3: M0 signifies no evidence of distant metastasis. Therefore, the correct answer is B because it accurately interprets the TNM staging system for the biopsy report. Summary: A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor. C: Incorrect - TIS already assesses tumor presence, ruling out this option. D: Incorrect - TIS is not about ascending degrees of distant metastasis.

Correct Answer: A

Rationale: Rationale: A relaxed face during conversation typically does not indicate a hearing loss, as the patient is likely able to hear and understand. B, speaking loudly, is a common sign of hearing loss. C, turning towards the speaker, suggests an effort to hear better. D, being withdrawn, could indicate difficulty in communication due to hearing loss. Therefore, A is the correct answer as it does not align with typical signs of hearing loss.

Correct Answer: B

Rationale: The correct answer is B because nurse-initiated interventions involve autonomous actions based on clinical judgment to achieve client outcomes. Nurses assess, plan, and implement care independently. Choice A involves physician orders, not nurse-initiated actions. Choice C relates to medical treatment, not nursing interventions. Choice D focuses on collaboration with other providers, not solely nurse-initiated actions. In summary, only choice B aligns with the independent and outcome-focused nature of nurse-initiated interventions.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Vitamin B12 is essential for the production of red blood cells, and its deficiency can lead to pernicious anemia, characterized by decreased red blood cell production. Without adequate vitamin B12, the body cannot properly utilize iron, leading to anemia. Iron deficiency anemia (choice A) is a result of insufficient iron levels, not vitamin B12 deficiency. Sickle cell anemia (choice B) is a genetic disorder affecting hemoglobin, not related to vitamin B12 deficiency. Acquired haemolytic anemia (choice D) is caused by the premature destruction of red blood cells, not by vitamin B12 deficiency.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Providing oral care does not directly address fluid balance or hydration status. 2. Oral care focuses on maintaining oral hygiene and preventing infections. 3. Choices A, B, and D all involve fluid intake to address dehydration. 4. Offering large amounts of fluid, enteral or parenteral fluids, and small volumes at frequent intervals all aim to correct the patient's condition by replenishing lost fluids. Summary: Choice C is incorrect because oral care does not directly address the patient's dehydration. Choices A, B, and D are better options as they focus on fluid replacement to correct the patient's condition.
