Correct Answer: A

Rationale: The nurse's priority should be attending to task assignments for the day. This ensures that client care can begin promptly and efficiently. Stocking the medication closet is important but can be done after ensuring task assignments are clear. Phone messages from employee health services and a client's wife, although important, can be addressed after organizing the staff for client care.

Correct Answer: D

Rationale: The nurse is responsible for ensuring client safety at all times and must not leave the nursing unit for any reason during the shift. The nurse's break should be taken in a designated area located on the nursing unit. Before taking the break, the nurse should check all clients to ensure that they are safe and comfortable and that their needs have been met. Conducting client rounds before taking the break is crucial to assess the clients' conditions and address any immediate needs, ensuring their safety. Asking the nursing assistant to contact the health care provider during the nurse's break is not appropriate as the nurse should handle this responsibility. Leaving the nursing unit to get coffee is not recommended as the nurse should stay within the unit to respond promptly to any client needs. Asking the nursing assistant to administer medication or make clinical decisions is outside the scope of their practice and should not be delegated.

Correct Answer: B

Rationale: The most likely cause of groups of individuals suddenly experiencing similar signs of illness all at once is a chemical exposure. In this scenario, considering the sudden onset of symptoms in multiple passengers on an airliner, the symptoms are more indicative of a chemical exposure rather than Asian flu, bacterial pneumonia, or an allergic reaction. Asian flu, bacterial pneumonia, and allergic reactions do not typically manifest in a way that would affect a group of individuals simultaneously. Therefore, the correct diagnosis in this case is likely to be a chemical exposure.

Correct Answer: B

Rationale: Informed consent is the authorization by a client or a client's legal representative to do something to the client. The surgeon is primarily responsible for explaining the surgical procedure and obtaining informed consent. If the client asks questions that alert the nurse to an inadequacy of comprehension on the client's part, the nurse has the obligation to contact the surgeon. Choice A is incorrect as the client should be allowed to ask questions even after signing the consent for surgery. Choice C is not the most appropriate response, as the primary concern is to address the client's lack of comprehension. Choice D is inaccurate, as while it is the surgeon's responsibility to explain the procedure, in this scenario, the nurse should take immediate action to ensure the client's understanding. Requesting the surgeon to visit and answer the client's questions is the most appropriate response in this situation, as it directly addresses the client's concerns and ensures proper informed consent is obtained.

Correct Answer: C

Rationale: Numbness and tingling hours or days after a cast is applied may indicate compartment syndrome and should be reported to a medical provider right away. This is a potential emergency situation that requires immediate attention to prevent complications. The other options present expected or typical symptoms related to their diagnosis, which do not require immediate intervention. Complaints related to a newly placed NG tube such as pain around the face and a plugged nose may require assessment and intervention but are not as urgent as potential compartment syndrome. Bladder spasms and blood in the foley bag post-prostatectomy are common postoperative issues that can be addressed after the client in the arm cast with potential compartment syndrome is seen. Stomach pain and itchy skin in a client with Hepatitis A are common symptoms of the condition and do not indicate an emergency situation.
