Correct Answer: B

Rationale: Setting the water heater at 130 degrees can lead to scald burns. The recommended temperature setting for water heaters is no higher than 120 degrees to prevent burns. Choice A is correct as it shows awareness of the risks of fireworks. Choice C is correct as flame-retardant sleepwear can help prevent burns. Choice D is correct as inward-facing pot handles prevent accidental spills and burns. Option B is incorrect due to the unsafe water heater temperature setting.

Correct Answer: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.

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 skull compliance and higher brain water content, making them more susceptible to developing symptoms like nausea and vomiting. Altered mental status (choice B) can occur in both children and adults but is not more common in children. Tachycardia and diaphoresis (choice C) are nonspecific and can occur in both age groups. Changes in pupillary reaction (choice D) are not typically more common in children following head trauma compared to adults.

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: B

Rationale: The correct approach for a child with a mild airway obstruction, respiratory distress, and normal skin color includes providing oxygen to support breathing, avoiding agitation that could worsen the situation, and arranging for transport to a healthcare facility. Option A is incorrect because abdominal thrusts are not recommended in a mild airway obstruction scenario, and back blows are typically used for choking. Option C is incorrect because assisting ventilations may not be necessary in a child with a strong cough and normal skin color. Option D is incorrect because chest thrusts are not recommended for a mild airway obstruction, and finger sweeps are used for foreign body airway obstructions.
