Correct Answer: A

Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.

Correct Answer: C

Rationale: The correct answer is C. Trimming toenails straight across and filing the edges is crucial in diabetic foot care to prevent ingrown toenails and foot injuries. Soaking feet daily can lead to dryness and skin breakdown, increasing the risk of infection. Selecting well-fitting shoes is important to prevent pressure points and skin damage, not tight-fitting shoes. Using heating pads can result in burns or injuries due to decreased sensation in diabetic feet, so it's essential to avoid them.

Correct Answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.

Correct Answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube system indicates an air leak. An air leak can prevent the lung from fully re-expanding and may lead to complications like a recurrent pneumothorax. Therefore, it is crucial to investigate and address the air leak promptly. Choices B and C are incorrect because continuous bubbling is not normal and does not indicate lung expansion. Choice D is incorrect because the nurse should first assess and then report the issue to the healthcare provider.

Correct Answer: B

Rationale: Orthodox Jews follow dietary laws (Kashrut) that prohibit mixing meat and dairy products in the same meal. This restriction is known as 'not mixing milk and meat.' Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because being an Orthodox Jew does not mean they can eat any food unless it is Yom Kippur, avoid meat on Ash Wednesday, or are necessarily vegetarian.
