Correct Answer: A

Rationale: Maternal dehydration can lead to a prolonged latent phase in labor due to inadequate hydration affecting the progress of labor. Dehydration can cause decreased blood volume, leading to poor uterine perfusion and inefficient uterine contractions. It also contributes to reduced amniotic fluid volume and can lead to maternal exhaustion. Therefore, assessment and correction of maternal hydration status are crucial in improving labor patterns and preventing complications during labor and delivery.

Correct Answer: B

Rationale: A "full understanding" in research should be understood by the nurse researcher as explaining the study including risks and ben . When conducting research involving participants, it is crucial for nurse researchers to provide all necessary information about the study, including potential risks and benefits, in a clear and understandable manner. This ensures that participants are well-informed and can make informed decisions about their participation. By explaining the study thoroughly, nurse researchers uphold ethical principles such as informed consent and respect for participants' autonomy. It also helps in building trust between the researcher and participants, ultimately leading to more reliable and ethical research outcomes.

Correct Answer: A

Rationale: Respondent superior is a legal doctrine that holds an employer (such as a nurse) responsible for the actions of their employees (such as a barangay health worker) performed within the scope of their employment. In the scenario provided, the nurse delegated tasks to the barangay health worker, making the health worker an agent of the nurse. By closely monitoring the delegated work, the nurse is fulfilling her legal responsibility under the principle of respondent superior to ensure that the health worker performs their duties properly and in accordance with professional standards.

Correct Answer: C

Rationale: When examining a child, especially one who may already be feeling scared or uncomfortable, it is important to prioritize the order of procedures to help maintain their cooperation and reduce their anxiety. Undressing the child is typically done first to ensure a thorough examination can be performed, and it is a less invasive procedure compared to others. Inspection of the throat with a throat stick and inspection of the ears with an otoscope are common procedures that may cause mild discomfort but are often tolerated well by children. Auscultation of the heart is usually done after these initial steps and is not typically as uncomfortable or frightening for children compared to other procedures. Therefore, auscultation of the heart should not be the last thing to do when examining a child to avoid frightening them.

Correct Answer: A

Rationale: In a patient with acute kidney injury (AKI) secondary to hypovolemic shock, the priority intervention to manage the patient's renal function is to administer intravenous fluids to restore circulating volume. Hypovolemic shock leads to decreased blood flow to the kidneys, resulting in hypoperfusion and ischemic damage to the renal tubules. Prompt correction of hypovolemia with intravenous fluids helps improve renal perfusion and function by increasing blood flow to the kidneys. Adequate fluid resuscitation can potentially prevent further kidney damage and support kidney function recovery. It is crucial to address the underlying cause of AKI (hypovolemia in this case) to prevent complications and improve patient outcomes. Initiating renal replacement therapy or recommending nephrotoxic medications would not be the initial interventions for managing AKI in this scenario.
