Correct Answer: D

Rationale: Full-thickness burns are characterized by a leathery, dry appearance with numbness due to nerve damage. Choice A describes characteristics of superficial burns, which are not full-thickness. Choice B describes characteristics of partial-thickness burns with intact blisters, not full-thickness burns. Choice C describes characteristics of partial-thickness burns with blistering and swelling, not full-thickness burns.

Correct Answer: D

Rationale: In hypospadias, the urethral opening is located along the ventral surface of the penis. This congenital condition results in the urethral meatus opening on the underside of the penis, rather than at the tip. Choice A is incorrect as there is typically a urethral opening present, though in an abnormal location. Choice B is not a characteristic feature of hypospadias. Choice C is incorrect as the urethral opening in hypospadias is not along the dorsal surface but rather along the ventral surface of the penis.

Correct Answer: C

Rationale: After eating, it is beneficial to place a child with GERD in a semi-Fowler's position. This position helps prevent reflux by keeping the child's head elevated above the stomach, reducing the chances of gastric contents flowing back into the esophagus. Placing the child supine (lying flat on their back) can worsen reflux symptoms by allowing gravity to work against the natural flow of gastric contents. Prone position (lying on the stomach) is not recommended due to the increased risk of aspiration. Trendelenburg position (feet elevated above head) is also inappropriate as it can lead to increased pressure on the abdomen, potentially worsening reflux symptoms.

Correct Answer: D

Rationale: Withholding extraordinary care in cases of severe abnormalities is a legal and ethical decision. It allows the newborn to die naturally without aggressive interventions. Choice A is incorrect because all individuals, including newborns, have rights. Choice B is incorrect because withholding extraordinary care is not equivalent to euthanasia, which involves actively ending a life. Choice C is incorrect because such decisions are legally and ethically permissible when made in consideration of the best interests of the newborn.

Correct Answer: A

Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.
