Correct Answer: B

Rationale: The correct answer is B: It minimizes the risk of circulatory overload. When a venous access device dislodges during a transfusion, there is a risk of the infusion going into the surrounding tissues instead of the vein, leading to circulatory overload. This can result in fluid overload and potentially lead to serious complications such as heart failure. Monitoring the device ensures that the medication is delivered safely and effectively into the bloodstream. Choices A, C, and D are incorrect: A: Monitoring the device does not directly minimize the risk of phlebitis, which is inflammation of the vein. C: Monitoring the device does not directly minimize the risk of pulmonary complications, which are not typically associated with a dislodged venous access device. D: Monitoring the device does not directly minimize the risk of localized edema embolism, which is a blockage caused by a blood clot, air bubble, or other material in a blood vessel.

Correct Answer: C

Rationale: The correct answer is C: Autoantibodies. In Hashimoto's thyroiditis, the immune system mistakenly attacks the thyroid gland by producing autoantibodies against thyroid proteins such as thyroglobulin and thyroid peroxidase. These autoantibodies lead to inflammation and destruction of thyroid tissue. Antigen-antibody complexes (choice A) are not the main mechanism in Hashimoto's thyroiditis. Viral (choice B) and bacterial infections (choice D) do not directly cause autoimmune destruction of the thyroid in this condition. Autoantibodies targeting the thyroid gland are the key pathogenic factor in Hashimoto's thyroiditis.

Correct Answer: A

Rationale: The correct answer is A: Bacterial meningitis. Bacterial meningitis is the most significant form due to its potential severity and rapid progression, requiring urgent medical intervention with antibiotics. Bacterial meningitis can lead to serious complications such as brain damage or death if left untreated. Septic meningitis (choice B) refers to meningitis caused by a systemic infection spreading to the meninges. Aseptic meningitis (choice C) is typically viral or non-bacterial in origin, usually milder than bacterial meningitis. Viral meningitis (choice D) is less severe than bacterial meningitis and often resolves on its own without specific treatment.

Correct Answer: A

Rationale: The correct answer is A. Before administering a narcotic analgesic like Morphine, assessing the client's level of alertness and respiratory rate is crucial to ensure they can tolerate the medication without compromising their breathing. Alertness indicates their ability to handle potential side effects, while respiratory rate is vital to monitor for any signs of respiratory depression. Choice B (last meal) is not directly related to giving a narcotic analgesic, although it may impact the absorption rate. Choice C (bowel habits) and last bowel movement are not immediately relevant to assessing the client's readiness for a narcotic analgesic. Choice D (history of addictions) is important but not the priority when assessing for immediate safety and efficacy of the medication.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates data validation in the nursing clinical decision-making process. The nurse assesses the time of the last dressing change and observes old and new drainage, which are relevant data points for wound care. This approach ensures that the decision to remove the dressing is based on accurate and validated information, leading to appropriate patient care. Choice B is incorrect because it relies on subjective information (increased pain and family request) rather than objective data validation. Choice C is incorrect as it involves a direct request for an order without sufficient data validation. Choice D is incorrect because elevating a leg cast based solely on a patient's report of decreased mobility does not involve thorough data validation related to the specific care needed for the patient's condition.
