Correct Answer: B

Rationale: The correct answer is to avoid exposing the irradiated area to direct sunlight. Direct sunlight can further damage the skin during radiation therapy. Choice A is incorrect because alcohol-based lotions can irritate the skin further. Choice C is incorrect because mild soap and water can be drying to the skin. Choice D is incorrect because applying ice packs can cause additional skin damage during radiation therapy.

Correct Answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

Correct Answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial in managing postoperative pain for the child. This helps control pain levels effectively, promoting comfort and aiding in the recovery process. Offering small amounts of clear liquids 6 hours following surgery may not be appropriate as the child may need time to recover from anesthesia. Giving cromolyn nebulizer solution every 6 hours is not indicated for postoperative care following appendicitis surgery. Applying a warm compress every 4 hours to the operative site may not be recommended as it can potentially interfere with the surgical wound healing process.

Correct Answer: A

Rationale: A heart rate of 78/min is within the normal range; however, postoperative patients require close monitoring for any signs of complications. While the heart rate is normal, other critical findings such as increased pain, excessive bleeding, or other concerning symptoms may need immediate attention. Choices B, C, and D all indicate normal postoperative vital signs and oxygen saturation levels, which do not raise immediate concerns requiring reporting to the provider.

Correct Answer: D

Rationale: The correct answer is D. After cataract surgery, wearing an eye shield at night for 2 weeks is essential to protect the eye during the initial healing period. Choice A is incorrect because significant eye pain should not be expected for the first 2 days after surgery. Choice B is incorrect as bending at the waist can increase intraocular pressure, which should be avoided postoperatively. Choice C is incorrect as there is no need to avoid sleeping on the side of the body that was operated on after cataract surgery.
