Correct Answer: C

Rationale: Delegating is the act of assigning work to those capable and competent to do the work, making it a task-related supervisory activity. Coaching, evaluating, and facilitating are people-related supervisory activities. Coaching involves guiding and developing individuals, evaluating entails assessing performance, and facilitating focuses on enabling tasks and processes. These activities are more centered on interacting with and supporting people rather than directly assigning tasks. Therefore, in the context of task-related activities, delegating stands out as the correct choice.

Correct Answer: A

Rationale: To infuse a 50 ml bolus in 30 minutes, the rate should be calculated as follows: 50 ml / 30 min = 100 ml per hour. Therefore, the correct answer is to set the pump rate at 100 ml per hour for one hour. Choice A is the correct rate based on the calculation. Choices B, C, and D all provide incorrect rates that do not match the physician's order. Choice B would only deliver 30 ml in 30 minutes, not the ordered 50 ml. Choice C would deliver 120 ml in one hour, which is 20 ml more than ordered. Choice D would only provide 25 ml over 30 minutes, not the full 50 ml prescribed.

Correct Answer: A

Rationale: Viewing crisis intervention as the first step in solving bigger problems is essential in a nurse who assists clients during crises. This approach focuses on addressing the immediate crisis first, which can potentially prevent the escalation of bigger problems. Wanting to help clients solve all problems identified (Choice B) may not be feasible or necessary during a crisis situation where immediate intervention is crucial. Taking an active role in guiding the process (Choice C) is important, but the primary focus should be on crisis intervention. Feeling that work requires identification with all of a client's problems (Choice D) may lead to a lack of focus on the immediate crisis at hand.

Correct Answer: A

Rationale: To protect the confidentiality of the information being reported, the nurse should make the charge nurse on the unit aware of the situation. This allows the charge nurse to take necessary steps to maintain confidentiality and ensure that the information is communicated in an appropriate and private manner. Disclosing the situation to the charge nurse is essential to address any breaches in confidentiality and uphold professional standards of privacy and ethics. Disregarding the information, returning to their own unit without disclosure, or ignoring the situation altogether would not address the breach of confidentiality and could lead to further issues regarding patient privacy and trust.

Correct Answer: C

Rationale: Estrogen antagonists are commonly used to treat estrogen hormone-dependent cancers such as breast carcinoma. One well-known estrogen antagonist used in breast cancer therapy is Tamoxifen (Nolvadex). This drug, in combination with surgery and other chemotherapeutic drugs, reduces breast cancer recurrence by 30%. Estrogen antagonists can also be administered to prevent breast cancer in women who have a strong family history. Thyroxine is a thyroid hormone used to treat hypothyroidism, not thyroid cancer. ACTH is an anterior pituitary hormone that stimulates the adrenal glands to release glucocorticoids; it does not treat adrenal cancer. Glucagon is a pancreatic alpha cell hormone that stimulates glycogenolysis and gluconeogenesis; it does not treat pancreatic cancer.
