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: A simple hysterectomy involves the removal of the uterus and cervix. It does not involve the removal of the fallopian tubes or ovaries. In some cases, the fallopian tubes may be removed along with the uterus, but this would be specified as a different type of hysterectomy (such as a total hysterectomy or a radical hysterectomy). The removal of the ovaries, if necessary, would be indicated as an oophorectomy.

Correct Answer: D

Rationale: An elevation of blood pressure would warrant stoppage of pills. High blood pressure, or hypertension, in a 4-year-old child is abnormal and needs prompt medical attention. Giving pills without monitoring or stopping them if blood pressure is elevated can lead to serious health complications. It is important to address the underlying cause of high blood pressure in a child, which may require further evaluation and management by a healthcare provider.

Correct Answer: C

Rationale: A pituitary adenoma is a type of benign tumor that arises from the pituitary gland, which is located at the base of the brain. When a pituitary adenoma grows large enough, it can compress surrounding structures, including the optic chiasm – the point at which the optic nerves cross over in the brain. Compression of the optic chiasm can lead to symptoms such as vision problems (e.g., visual disturbances), headaches, and nausea/vomiting, which are consistent with the presentation described in the question. Meningiomas, glioblastoma multiforme, and medulloblastomas are less likely to compress the optic chiasm and present with different characteristic symptoms based on their locations and growth patterns.

Correct Answer: C

Rationale: Globulin is the blood protein involved in the immune system. There are different types of globulins, including immunoglobulins (antibodies) that play a crucial role in the body's defense against infections. These antibodies bind to foreign substances, such as bacteria and viruses, helping the immune system to recognize and destroy them. Thrombin is a clotting protein, albumin is a protein responsible for maintaining osmotic balance in the blood, and hemoglobin is a protein found in red blood cells that carries oxygen.

Correct Answer: C

Rationale: Monitoring cardiac enzymes would be most helpful to Nurse Victor to confirm the underlying cause of cardiogenic shock. Cardiac enzymes are specific markers in the blood that indicate damage to the heart muscle, such as troponin and creatine kinase-MB (CK-MB). When a patient experiences cardiogenic shock, there is usually damage to the heart muscle which leads to the release of these enzymes into the bloodstream. Monitoring cardiac enzymes can help confirm if the cause of cardiogenic shock is related to myocardial infarction or another cardiac issue. This information is crucial for determining the appropriate treatment and management plan for the patient. Monitoring pulmonary artery pressure, mean arterial pressure, and central venous pressure may provide important hemodynamic information but may not directly confirm the underlying cause of cardiogenic shock.

Correct Answer: C

Rationale: Meperidine (Demerol) is an opioid analgesic. Overdose of Meperidine can lead to respiratory depression, characterized by slow and shallow breathing. As a result of respiratory depression, hypercapnia, which is an increased level of carbon dioxide in the blood, can occur. This is a serious concern and requires immediate medical intervention to support respiratory function. Therefore, hypercapnia would be the assessment by the nurse that causes a concern for Meperidine overdose.

Correct Answer: C

Rationale: In this situation, the most appropriate way for the nurse to handle it would be to encourage the mother to keep calm because the health care team is doing their best to help Ramon recover. This response acknowledges the mother's concerns and reassures her that everything possible is being done for her son's well-being. It also helps to foster trust and rapport between the nurse, mother, and the healthcare team, which is important for effective communication and support during a challenging time. Promoting a sense of calm and trust in the healthcare professionals can help alleviate the mother's anxiety and stress, allowing her to focus on being a supportive presence for her son.

Correct Answer: D

Rationale: Filipinos have generally low awareness about osteoporosis. Despite the increasing number of cases in the country, many Filipinos still lack knowledge about the disease and its risk factors. Osteoporosis is a significant health concern in the Philippines, especially among the elderly population, but there is still a need for more education and awareness campaigns to improve prevention and management strategies.
