Tension pneumothorax can be caused by:

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Tension pneumothorax can be caused by a variety of factors, including "Flail chest," which leads to air accumulation in the pleural space. Cardiac tamponade can also cause tension pneumothorax due to increased pressure on the lungs. Clamping of a chest tube can result in tension pneumothorax if the built-up air cannot escape. Therefore, all of these choices can lead to tension pneumothorax by causing an increase in intrathoracic pressure, ultimately leading to respiratory distress.

Correct Answer: D

Rationale: The correct answer is D: Medicare will pay for care that it determines to be medically necessary. Medicare follows guidelines to determine what services are medically necessary based on the patient's condition. This ensures appropriate and effective use of resources. Choices A, B, and C are incorrect because Medicare does not cover all care simply because it is requested by the recipient, doctor, or facility. It must meet the criteria of being medically necessary to be covered by Medicare.

Correct Answer: B

Rationale: The correct answer is B because documenting care accurately and promptly is a crucial aspect of professional and ethical behavior for a nursing assistant. This helps ensure continuity of care, patient safety, and accountability. It is important to maintain accurate records for effective communication among healthcare team members. Choice A is incorrect because staying quiet about mistakes can compromise patient safety and is not transparent or accountable behavior. Choice C is incorrect because sharing confidential information with friends violates patient privacy and confidentiality. Choice D is incorrect because rushing a resident through tasks compromises the quality of care and may lead to errors or neglect.

Correct Answer: D

Rationale: The correct answer is D because cultural background influences communication styles, values, and beliefs. Understanding a resident's cultural background helps the NA communicate effectively by respecting their customs and preferences. It promotes better rapport and trust between the NA and the resident, leading to improved quality of care. Choice A is incorrect as cultural background plays a crucial role in communication. Choice B is incorrect as not all residents may want to share stories about their culture. Choice C is incorrect as personal connections may not always be relevant or appropriate in the caregiving context.

Correct Answer: A

Rationale: The correct answer is A because patient safety and well-being should be the top priority in healthcare settings. By answering the call light promptly, the nursing assistant ensures the resident receives timely assistance. Ignoring the call light (choice D) goes against the duty of care and could lead to potential harm for the resident. Telling the supervisor (choice C) may cause unnecessary delays in addressing the resident's needs. While informing the assigned nursing assistant (choice B) is a proactive step, it is more efficient for the assistant who sees the call light to respond immediately to ensure the resident's needs are met without delay.
