Correct Answer: B

Rationale: The correct answer is B: “Rotate injection sites within the same anatomic region, not among different regions.” This instruction is important to prevent lipodystrophy and ensure consistent insulin absorption. Rotating sites within the same region helps maintain consistent insulin absorption rates and reduces the risk of developing scar tissue or fatty deposits. Injecting into healthy tissue with large blood vessels and nerves (choice A) can lead to inconsistent absorption. Administering insulin into areas of scar tissue or hypotrophy (choice C) can also disrupt absorption. Injecting into sites above muscles planned for exercise (choice D) can lead to unpredictable insulin absorption. Rotation within the same region optimizes insulin delivery and prevents complications.

Correct Answer: A

Rationale: The correct answer is A: Confusion or delirium can be a defense against further stress. This is because providing new information slowly and in small amounts can help prevent overwhelming Mr. Reyes, who is already confused. This approach allows him to process and understand the information more effectively without adding to his stress levels. Choices B, C, and D are incorrect: B: Destruction of brain cells has occurred, interrupting mental activity - This is not the most appropriate explanation as it assumes irreversible damage to the brain, which is not mentioned in the question. C: Teaching based on information progressing from the simple to the complex - While this may be a valid teaching strategy in general, it does not address Mr. Reyes' specific state of confusion and the need to reduce stress. D: A minimum of information should be given, since he is unaware of surrounding - This choice does not address the underlying reason for providing information slowly, which is to manage stress and confusion, rather than solely focusing on the

Correct Answer: B

Rationale: The correct answer is B because the nurse should primarily communicate with the patient, not just the daughter. The nurse should engage the patient in conversation, address them directly, and ensure their needs and concerns are being addressed. Speaking only to the daughter could neglect the patient's autonomy and lead to potential communication barriers. Choices A, C, and D are incorrect as they all involve appropriate communication techniques with the patient, such as making eye contact, leaning forward to show attentiveness, and nodding to indicate understanding. These actions demonstrate good communication skills and rapport-building with the patient, which are important in nursing practice.

Correct Answer: A

Rationale: The correct answer is A: A hemolytic reaction to mismatched blood. Chills, dyspnea, and urticaria are indicative of a hemolytic transfusion reaction, which occurs when the recipient's immune system attacks the donor's red blood cells. This can lead to various symptoms, including fever, chills, difficulty breathing, and hives. This type of reaction is most commonly seen with mismatched blood types. Option B (A hemolytic reaction to Rh-incompatible blood) is incorrect because Rh incompatibility typically leads to hemolytic disease of the newborn, not an immediate transfusion reaction. Option C (A hemolytic allergic reaction caused by bacterial contamination of donor blood) is incorrect as bacterial contamination would present with symptoms such as fever and sepsis, not chills, dyspnea, and urticaria. Option D (None of the above) is incorrect as the symptoms presented align with a hemolytic transfusion reaction.

Correct Answer: B

Rationale: The correct answer is B because it provides a specific action (offering water) at regular intervals (every 2 hours) to promote hydration, which is a clear and measurable nursing intervention. Choice A is too prescriptive and lacks flexibility. Choice C is reactive and not proactive. Choice D is vague and lacks specific guidance on how to achieve the desired outcome. By offering water consistently, the nurse ensures proactive care and helps meet the client's hydration needs effectively.
