Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.

Rationale: Cultural differences are a common barrier to effective communication in healthcare. When individuals from different cultures interact in healthcare settings, varying communication styles, beliefs, values, and language barriers can hinder effective communication. This can lead to misunderstandings, misinterpretations, and ultimately impact the quality of care provided. Active listening (choice A) is a communication skill that helps improve understanding and can actually enhance communication. Clear language (choice C) is essential for effective communication and can help overcome barriers, rather than being a barrier itself. Empathy (choice D) is important in healthcare to understand patients' emotions and perspectives, but it is not a common barrier to effective communication.

Correct Answer: A

Rationale: Providing clear and understandable instructions can help improve patient adherence to treatment plans. Clear instructions help patients better understand their treatment plans, leading to increased compliance. Choices B, C, and D are incorrect.

Ignoring patient feedback can lead to misunderstandings and hinder the patient's commitment to the treatment plan.

It is recommended to take metformin with meals to reduce gastrointestinal side effects. Option B is incorrect as metformin is usually taken with meals. Option D is also incorrect as metformin does not inhibit the absorption of carbohydrates.
