Which of the following statements accurately describes the role of dendritic cells in the immune response?

Correct Answer: C

Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.

Correct Answer: C

Rationale: When a postpartum client exhibits signs of wound infection, such as erythema, warmth, and purulent drainage from a cesarean incision, it is essential to notify the healthcare provider immediately. Wound infections can lead to serious complications if not promptly addressed. The healthcare provider will assess the infection, possibly order further diagnostic tests, and determine the appropriate course of treatment, which may include antibiotics or additional wound care measures. Applying a dressing or irrigating the wound may be part of the treatment plan prescribed by the healthcare provider, but the first step is always to seek guidance from the provider.

Correct Answer: B

Rationale: Type I IgE-mediated immediate hypersensitivity reactions, such as anaphylaxis, are promptly managed with epinephrine. Epinephrine is the first-line treatment for anaphylaxis as it helps counteract the severe symptoms by relaxing the muscles in the airways, constricting blood vessels, and decreasing swelling. It acts quickly to reverse the potentially life-threatening effects of the allergic reaction and is crucial in managing anaphylaxis effectively. Other medications like antihistamines (e.g., diphenhydramine) and corticosteroids may be used as adjuncts, but epinephrine remains the primary treatment for immediate hypersensitivity reactions.

Correct Answer: B

Rationale: The most effective treatment for addressing the underlying pathophysiology of cystic fibrosis (CF) and preventing disease progression is the use of mucolytic agents, such as dornase alfa. CF is a genetic disorder that leads to the production of thick, sticky mucus in the respiratory tract. This mucus buildup can obstruct airways, lead to recurrent infections, and contribute to pulmonary exacerbations. Mucolytic agents work by reducing the viscosity of the mucus, making it easier to clear from the airways. This helps to improve lung function, reduce the frequency of exacerbations, and slow down disease progression in CF patients. Inhaled corticosteroids may be used for managing airway inflammation, but they do not target the underlying mucus production in CF. Antibiotic therapy is important for treating respiratory infections in CF patients, but it does not address the primary

Correct Answer: C

Rationale: The nurse should reposition the patient to alleviate pressure on vulnerable areas. Pressure injuries can develop when there is prolonged pressure on specific areas of the skin, leading to reduced blood flow and tissue damage. Repositioning the patient helps to relieve the pressure and prevent the development of pressure injuries. Applying a pressure-relieving device may also be helpful, but the immediate action should be to reposition the patient to address the issue. Documenting the observation is important for documentation purposes, but the priority is to take action to prevent harm to the patient. Continuing with the positioning as planned without addressing the inadequate skin protection could lead to the development of pressure injuries, which should be avoided.

Correct Answer: C

Rationale: In Participative Action Research (PAR), the core idea is to empower the community by involving them in the research process. By actively engaging community members in all stages of the research, they gain a sense of ownership and are empowered to take action based on the research findings. This approach ensures that the solutions generated are relevant, sustainable, and community-driven. Therefore, participation and engagement of the community is the step that will empower the community in PAR, unlike the other options where the focus is on external individuals or entities.

Correct Answer: A

Rationale: Assessing the infant's latch and feeding effectiveness should be prioritized as the initial nursing intervention to address the client's concerns about inadequate milk supply. Poor latch can lead to ineffective milk removal, which may result in decreased milk production. By ensuring the infant is latching correctly and effectively transferring milk, the client's milk supply can be optimized. Education about techniques to increase milk production can be provided following the assessment of feeding effectiveness. Referring to a lactation consultant may be necessary for further evaluation and support if issues persist despite correcting the latch. Supplemental formula feedings should be recommended as a last resort after all other interventions have been attempted and if there are concerns about inadequate nutrition for the infant.

Correct Answer: D

Rationale: The Philippine Regulatory Commission - Board of Nursing (PRC-BON) has the power to regulate nursing practice in the Philippines.

Correct Answer: A

Rationale: Assisting the mother into a hands-and-knees position should be prioritized to facilitate fetal rotation and optimize labor progress in the case of persistent occiput posterior fetal position. This position helps in promoting fetal rotation to a more favorable position for delivery by allowing the baby's head to move into the anterior position. It can help alleviate back pain and may help reduce the duration of labor. This simple maneuver can sometimes correct the malposition without the need for interventions like instrumental delivery. It is a non-invasive and effective technique that can be easily implemented by healthcare providers to support the progression of labor.
