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: B

Rationale: The primary purpose of a cervical collar in the management of trauma patients is to immobilize the cervical spine. This is crucial in cases of suspected cervical spine injury to prevent any further damage and to maintain spinal stability. By providing support and restricting movement in the cervical spine region, a cervical collar helps prevent potential spinal cord injuries and associated neurological deficits. It is essential to immobilize the cervical spine until a thorough evaluation can be carried out to determine the extent of injury, as any movement of the spine during this period can worsen the damage.

Correct Answer: C

Rationale: Sevelamer is a medication commonly prescribed to reduce serum phosphate levels in patients with chronic kidney disease. Sevelamer is a phosphate binder that works by binding to dietary phosphate in the gut, preventing its absorption into the bloodstream. By reducing serum phosphate levels, sevelamer helps manage complications associated with hyperphosphatemia in chronic kidney disease patients, such as mineral and bone disorders. Other medications like epoetin alfa are used to treat anemia commonly seen in chronic kidney disease patients, while cinacalcet is used to manage secondary hyperparathyroidism. Allopurinol, on the other hand, is used to treat gout by reducing uric acid levels and is not indicated for reducing serum phosphate levels in chronic kidney disease patients.

Correct Answer: C

Rationale: Cleaning the inner cannula daily helps prevent the accumulation of secretions and debris, which can lead to blockages and infections. It is an essential aspect of tracheostomy care to maintain the patency of the airway and prevent complications. Caregivers should be taught how to safely remove, clean, and reinsert the inner cannula as part of routine tracheostomy care.

Correct Answer: A

Rationale: In a community clinic providing primary care for patients, the most common healthcare professional who manages patient care is a physician. Physicians, also known as doctors, are trained and licensed to diagnose and treat a wide range of medical conditions. They are responsible for conducting exams, prescribing medications, ordering tests, and developing treatment plans for patients. While other healthcare professionals such as nurses, midwives, and barangay health workers also play important roles in providing care, physicians typically lead the team, make critical decisions, and provide overall management of patient care in a primary care setting like a community clinic.

Correct Answer: C

Rationale: Uterine rupture is a serious obstetric emergency that involves a tear or rupture of the uterine wall during pregnancy. In this scenario, the pregnant woman with severe lower abdominal pain, vaginal bleeding, and a tender, distended abdomen is showing signs consistent with uterine rupture. These symptoms are typically not seen with other conditions listed.

Correct Answer: C

Rationale: The theory of Nursing as Caring was developed by Dr. Jean Watson, a renowned nurse theorist and professor. Watson's Theory of Human Caring focuses on the importance of the nurse-patient relationship, emphasizing the significance of caring in promoting healing and promoting holistic well-being. This theory emphasizes the humanistic aspects of nursing care and highlights the nurse's role in fostering a caring environment that encompasses physical, emotional, social, and spiritual dimensions. Watson's theory emphasizes the importance of empathy, compassion, and authentic presence in nursing practice, making it a valuable framework for guiding nursing care and promoting healing outcomes.

Correct Answer: A

Rationale: Ambivalence is the most common emotional response among women during the first trimester of pregnancy. This is because the news of being pregnant might evoke a mix of emotions, including joy and apprehension. Women may feel uncertain about their readiness for the responsibility of motherhood, have concerns about changes in their body, or worry about the impact on their career or relationships. Ambivalence is a natural response to a significant life change, and many women experience conflicting feelings before fully accepting and embracing their pregnancy.

Correct Answer: D

Rationale: Since Nadine is just four years old, determining her favorite toys is not a critical aspect for Nurse Alma to consider in terms of routines and rituals. While knowing Nadine's favorite toys may help provide comfort or distraction, it is not as essential as ensuring proper feeding, sleep patterns, and toilet training for a young child's well-being and development. The focus should primarily be on aspects that directly impact her physical health, growth, and daily routines at this age.
