Correct Answer: C

Rationale: Feedback is an essential indicator of effective communication because it allows the sender to understand how the message was received by the receiver. It provides an opportunity to clarify any misunderstandings, confirm understanding, and ensure that the communication has been successful. Without feedback, the sender cannot be sure if their message was accurately understood or if further explanation or clarification is needed. Effective communication involves a two-way exchange, and feedback plays a crucial role in ensuring that the message is effectively transmitted and received.

Correct Answer: B

Rationale: Cell-mediated immunity is a type of immune response that involves the activation of cytotoxic T cells and other immune cells to directly target and destroy infected or abnormal cells. It does not involve the production of antibodies, which are the primary component of humoral immunity. Antibodies are produced by B cells and are responsible for targeting extracellular pathogens such as bacteria and viruses. In contrast, cell-mediated immunity is more focused on targeting intracellular pathogens, cancerous cells, and other cells that have been compromised. So, production of antibodies is not usually associated with cell-mediated immunity.

Correct Answer: B

Rationale: Total care nursing is a nursing care delivery model where one nurse is assigned to provide comprehensive care to a patient for an entire shift. In this case, the private duty nurse is providing holistic care to the post-caesarian patient during the shift, which aligns with the principles of total care nursing. This approach allows the nurse to focus on the individual needs of the patient and provide all aspects of care, promoting continuity and personalized attention. Total care nursing ensures that the patient receives consistent and dedicated care from the same nurse, enhancing the patient's overall experience and outcomes.

Correct Answer: A

Rationale: Encouraging frequent position changes, including the hands-and-knees position, is the most appropriate nursing intervention in this scenario. This position is known to help rotate the baby from a persistent posterior position to an optimal anterior position for delivery. The hands-and-knees position can help take pressure off the mother's back, alleviate back pain, and facilitate the rotation of the baby's head to engage in the mother's pelvis, thus promoting labor progress. It is a non-invasive and effective way to promote fetal rotation without the need for immediate instrumental delivery or intravenous analgesics. Continuous fetal monitoring is important for assessing fetal well-being but would not directly address the issue of posterior fetal position and the associated prolonged labor.

Correct Answer: A

Rationale: The nurse should prioritize adjusting the irrigation flow rate based on the patient's urine output to prevent complications during continuous bladder irrigation (CBI). Proper adjustment of the irrigation flow rate helps maintain adequate bladder drainage while preventing bladder distention, clot formation, and potential irrigation fluid overload. Monitoring the patient's urine output and adjusting the flow rate accordingly ensures optimal functioning of the CBI system and enhances patient safety. This proactive approach minimizes the risk of complications and promotes effective postoperative care following urological surgery.
