Correct Answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn's skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.

Correct Answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body's immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

Correct Answer: B

Rationale: The correct answer is B: Guided imagery. Guided imagery is an effective distraction technique for adolescents as it helps them focus on positive mental images instead of the pain. This technique can be a powerful tool in managing pain and anxiety during procedures. Blowing bubbles (choice A) may be more suitable for younger children as it can engage them visually and help distract them. EMLA cream (choice C) is a topical anesthetic and not a distraction technique. Sucrose solution (choice D) is used for pain relief in infants, not typically for adolescents undergoing painful procedures.

Correct Answer: D

Rationale: Evidence-based practice involves gathering and integrating all relevant evidence to guide clinical decision-making, ensuring that care is based on the best available research.
