Correct Answer: A

Rationale: The nurse should inform the public that rabies can be prevented. This is an extremely important piece of information to help raise awareness about the disease and promote preventive measures such as timely vaccination of both animals and humans. Rabies is a deadly viral infection that affects the central nervous system, and prevention through vaccination is highly effective in controlling its spread. By emphasizing the preventability of rabies, the nurse can educate the public on the importance of taking proactive steps to avoid contracting the disease.

Correct Answer: C

Rationale: If the nurse observes an unusual odor emanating from the surgical site during surgery, it is important to inform the surgeon immediately and assess for signs of infection. Changes in odor can sometimes be an early sign of infection, which requires prompt attention and intervention. By communicating with the surgeon and conducting a thorough assessment, the nurse can help ensure the timely detection and management of any potential complications, such as infection, that may be affecting the patient's surgical outcome. Prompt action in response to unusual observations is crucial to maintaining patient safety and well-being during surgical procedures.

Correct Answer: C

Rationale: In qualitative research, a focus group discussion is a technique where a group of participants are brought together to discuss specific topics in depth. In this case, Nurse Carmi's plan to gather 6 participants who are victims of domestic violence aligns well with the focus group discussion technique. By involving multiple participants who have experienced domestic violence, she can facilitate a dynamic conversation to gather rich data and insights. This approach allows for the exploration of diverse perspectives, experiences, and opinions within the group setting, providing a deeper understanding of the issue at hand. Additionally, focus group discussions can be more cost-effective and efficient than conducting individual interviews when working with a small group of participants. Therefore, conducting a focus group discussion would be an appropriate qualitative research technique for Nurse Carmi's plan to gather data from victims of domestic violence for her questionnaires.

Correct Answer: C

Rationale: Type 2 diabetes mellitus is characterized by insulin resistance in the peripheral tissues and defective beta cell secretion with loss of insulin. In type 2 diabetes, there is typically not destruction of beta cells from an autoimmune mechanism that leads to lack of insulin and hyperglycemia as seen in type 1 diabetes mellitus. Instead, in type 2 diabetes, the pancreas initially produces insulin, but the body's cells become resistant to its effects. This results in hyperglycemia due to the inability of the body to properly regulate blood sugar levels. Therefore, choice C is not true for type 2 diabetes mellitus.

Correct Answer: D

Rationale: In the scenario described, the patient is experiencing severe hypoxemia refractory to conventional oxygen therapy, indicating a need for advanced respiratory support. When a patient with ARDS fails to respond to conservative management, including mechanical ventilation strategies, prone positioning, and recruitment maneuvers, the next step may involve extracorporeal membrane oxygenation (ECMO). ECMO provides a way to bypass the lungs and oxygenate the blood directly, allowing for enhanced gas exchange and support for severely compromised respiratory function. Therefore, in this critical situation, prioritizing the recommendation for ECMO can offer the patient the best chance of improving oxygenation and survival.
