During a clinical conference with a group of nursing students, the instructor is describing burn classifications. The instructor determines that the teaching has been successful when the group identifies what as characteristic of full-thickness burns?

Correct Answer: D

Rationale: Full-thickness burns, also known as third-degree burns, are characterized by a leathery, dry appearance with numbness due to nerve damage. This type of burn extends through all layers of the skin, affecting nerve endings. Choice A describes characteristics of superficial partial-thickness burns, which involve the epidermis and part of the dermis. Choice B describes characteristics of superficial burns, or first-degree burns, which only affect the epidermis. Choice C describes characteristics of superficial to mid-dermal burns, also known as second-degree burns, which involve the epidermis and part of the dermis but do not extend through all skin layers. Therefore, the correct answer is D.

Correct Answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less space for swelling within the skull compared to adults, making them more prone to experiencing symptoms like nausea and vomiting. Altered mental status and changes in pupillary reaction can also occur in both children and adults following head trauma, but they are not specifically more common in children. Tachycardia and diaphoresis are generally signs of autonomic nervous system activation and may occur in both children and adults, but they are not typically more common in children compared to adults following head trauma.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.

Correct Answer: D

Rationale: In congenital hypothyroidism, infants often experience lethargy and difficulty staying awake due to low thyroid hormone levels. Choice A is incorrect as hypothyroidism can lead to poor growth in infants. Choice B is incorrect because hypothyroidism can cause decreased activity levels and lethargy rather than being active and playful. Choice C is incorrect as hypothyroidism can result in dry skin and poor skin tone, not necessarily pink and healthy-looking skin.

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: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.

Correct Answer: A

Rationale: The priority nursing action after a child has undergone tracheostomy surgery is to suction the tracheostomy tube. Suctioning is crucial to maintain a clear airway, remove secretions, and prevent potential airway obstruction, which is essential for the child's respiratory function. Changing the tracheostomy dressing, while important for wound care, does not take precedence over airway clearance. Monitoring respiratory status is vital but comes after ensuring airway patency. Ensuring tracheostomy ties are secure is significant for stabilizing the tube but is not as urgent as maintaining a patent airway through suctioning.

Correct Answer: B

Rationale: Cellulitis is characterized by warmth at the site of skin disruption, indicating an infection. The correct answer is choice B. Choice A, 'Red, raised hair follicles,' is more indicative of folliculitis rather than cellulitis. Choice C, 'Papules progressing to vesicles,' is more characteristic of conditions like chickenpox, not cellulitis. Choice D, 'Honey-colored exudate,' is typical of wound infections with bacteria like Staphylococcus aureus, not cellulitis.
