Rationale: All of the components -explanation of the procedure and alternatives to the procedure (I), discussion of potential risks and benefits of the procedure (II), and confirmation that the patient understands the risks, benefits, and any alterations (III) -are essential parts of informed consent. Providing information about the procedure and its alternatives, disclosing potential risks and benefits, and ensuring that the patient comprehends this information are crucial to obtaining valid informed consent prior to any medical procedure.

Rationale: Feces, urine, blood, and other body fluids are considered as vehicles of transmission in the context of communicable diseases. These substances can carry and transmit disease-causing microorganisms such as bacteria, viruses, and parasites from infected individuals to others. Through close contact or exposure to these contaminated body fluids, the pathogens can enter the body of another person and cause infection. Nurses like Nurse Keena must exercise caution and use appropriate infection control measures to prevent transmission of communicable diseases through these vehicles.

Correct Answer: C

Rationale: Verbal abuse is the most common form of abuse experienced by nurses in their workplace. This may include insults, yelling, threats, or intimidation directed towards the nurse. Verbal abuse can have a significant impact on the nurse's mental and emotional well-being, leading to stress, anxiety, and burnout. It is important for healthcare institutions to address and prevent verbal abuse to create a safe and respectful work environment for nurses and other healthcare professionals.

Rationale: In qualitative research, the focus is on exploring a phenomenon in-depth, understanding experiences, perceptions, and meanings. Unlike quantitative research, qualitative research does not typically start with a hypothesis to be tested. Instead, qualitative studies often use open-ended questions and flexible methods to gather rich, detailed data that can lead to new insights and theories. The other options - sample, literature review, and data collection - are essential components of the qualitative research process.

Correct Answer: B

Rationale: The priority nursing diagnosis for a patient undergoing surgery (closure of the sac) would be risk for infection. This is because surgical procedures increase the risk of infection due to the breach in the skin and introduction of microorganisms. Infection can lead to serious complications, delay healing, and prolong recovery time. Therefore, prevention, early detection, and prompt treatment of infections are essential in the perioperative period to ensure the best possible outcomes for the patient.
