Correct Answer: A

Rationale: Osteoporosis is a common complication associated with long-term use of corticosteroids in orthopedic patients. Corticosteroids can lead to bone loss by inhibiting bone formation and promoting bone resorption, resulting in decreased bone mineral density and increased risk of fractures. Therefore, patients on long-term corticosteroid therapy, especially in high doses, should be monitored closely for osteoporosis and receive appropriate preventive measures such as calcium, vitamin D supplementation, and bisphosphonates to mitigate the risk of bone thinning and fractures.

Correct Answer: C

Rationale: Incident reports are a crucial tool for capturing data on adverse events, near misses, and other incidents within a healthcare institution. These reports help in analyzing patterns, identifying areas for improvement, and implementing quality and safety measures. Therefore, incident reports themselves are not something that needs to be prevented; instead, they are a critical part of the risk management process to enhance patient safety and quality of care.

Correct Answer: C

Rationale: When caring for patients with hyperbilirubinemia, the nursing care plan should focus on informing the significant others, preventing injury, and preventing complications. The primary goal in managing hyperbilirubinemia is to prevent complications associated with high bilirubin levels, such as kernicterus. Therefore, maintaining physiological homeostasis with bilirubin levels increasing would not be appropriate and should not be the focus of the nursing care plan. It is crucial to monitor and manage bilirubin levels to prevent adverse outcomes rather than allowing them to increase.

Correct Answer: A

Rationale: The presentation of a palpable, non-tender mass in the right neck, just below the angle of the mandible, along with ultrasound imaging findings of a well-defined, hypoechoic lesion with cystic components, is classic for a branchial cleft cyst. Branchial cleft cysts are congenital anomalies that arise from remnants of the branchial clefts or pouches during embryonic development. They are typically located along the anterior border of the sternocleidomastoid muscle, just below the mandible. Ultrasound imaging often shows a cystic lesion with well-defined borders and hypoechoic content, which is consistent with the described findings. Thyroglossal duct cysts usually present as midline neck masses that move with swallowing or tongue protrusion, not in the location described in the scenario. Lymphadenopathy would present as enlarged lymph nodes that may be tender and associated with systemic symptoms.

Correct Answer: C

Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to painless vaginal bleeding during pregnancy. In the scenario described, the painless, bright red vaginal bleeding at 34 weeks gestation with a closed cervix is classic for placenta previa. This condition is more common in the third trimester and can be diagnosed through ultrasound. It is important to manage placenta previa carefully to prevent complications such as severe bleeding, preterm birth, and maternal/fetal distress.
