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: D

Rationale: The correct answer is D because individuals with AB blood type are considered universal recipients, meaning they can receive blood from any blood type without risking complications due to incompatibility. This is because their blood cells have both A and B antigens and do not produce antibodies against either type. Therefore, the client can safely receive blood from types A, B, AB, or O without adverse reactions. Choices A, B, and C are incorrect because they limit the options for blood transfusion based on the client's AB blood type, which is not necessary given the unique nature of AB blood as universal recipients.

Correct Answer: C

Rationale: The correct answer is C because it helps the patient explore her support system. By asking who she usually goes to when facing problems, the nurse encourages the patient to identify her sources of emotional support, which can help her cope with the new diagnosis. This response acknowledges the patient's need for support and fosters a therapeutic relationship. Explanation for incorrect choices: A: "Don't worry. You'll be okay." - This response dismisses the patient's feelings and offers false reassurance, which may not address her emotional needs. B: "The treatments you are receiving will make you feel better very soon." - While this statement provides information about treatment, it does not directly address the patient's difficulty in coping with the diagnosis. D: "Have you made end-of-life decisions?" - This response may be premature and could unnecessarily increase the patient's anxiety about her prognosis.

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.

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.
