Correct Answer: D

Rationale: When caring for a client receiving brachytherapy, it is crucial to handle radioactive sources appropriately. Discarding the radioactive source in a biohazard bag is essential to prevent exposure to radiation. Cleaning equipment before removal, limiting client's visitors, or discarding linens in a double bag are not specific to the management of radioactive sources in brachytherapy.

Correct Answer: D

Rationale: In a client experiencing drooling and hoarseness following a burn injury, airway compromise is a critical concern. Administering 100% humidified oxygen is the priority to ensure adequate oxygenation. This intervention takes precedence over obtaining baseline ECG, obtaining blood specimens, or inserting an IV catheter, as airway management and oxygenation are fundamental in the initial assessment and management of a client with potential airway compromise.

Correct Answer: A

Rationale: When a client in a seclusion room following violent behavior continues to display aggression, it is essential for the nurse to confront the client about this behavior. Confrontation can help set boundaries, address the behavior, and ensure the safety of both the client and the healthcare team. Expressing sympathy (Choice B) may not address the immediate need for behavior management. Speaking assertively (Choice C) can be important but should be coupled with addressing the specific behavior. Standing within close proximity (Choice D) of an aggressive client can escalate the situation and compromise safety, so it is not the appropriate action to take.

Correct Answer: C

Rationale: Postterm pregnancy with oligohydramnios is a contraindication for the use of oxytocin due to the increased risk of uterine hyperstimulation and fetal distress. Oxytocin can further stress the fetus in this scenario, potentially leading to adverse outcomes. Therefore, it is crucial for the nurse to recognize this contraindication to ensure the safety of both the mother and the baby during labor.
