The physician tells the parents of a 2-year-old that the child probably has RSV. The parents ask how the diagnosis will be confirmed. How should the nurse respond?

Correct Answer: A

Rationale: The correct answer is A. RSV is typically diagnosed by swabbing the nose and testing the secretions. This method helps confirm the presence of the respiratory syncytial virus. Choice B is incorrect because while symptoms are important in diagnosis, specific tests like swabbing for RSV do exist. Choice C is incorrect as sending a viral culture to an outside lab is not the primary method for diagnosing RSV. Choice D is a duplicate of choice B and is incorrect for the same reasons.

Correct Answer: D

Rationale: The correct answer is D. Preschool-age children often attribute illness to their actions, like yelling at a sibling or not following instructions. They may not understand medical causes such as exposure to infections like strep throat (choice A), dietary factors (choice B), or vitamin deficiencies (choice C). It is common for young children to connect symptoms to recent behaviors or events within their limited understanding.

Correct Answer: B

Rationale: The Numeric scale is the most appropriate tool for assessing pain in older children, like a 12-year-old, as they can comprehend and use numbers to indicate their pain levels accurately. The FLACC scale is typically used for nonverbal or preverbal children. The NIPS scale is designed for neonates and infants. The FACES scale is more commonly used in younger children who may have difficulty expressing their pain in other ways.

Correct Answer: D

Rationale: The correct answer is D: 'Before meals'. Chest physiotherapy should be performed before meals to reduce the risk of vomiting and to ensure that the airways are clear for effective nutrition. Choices A, B, and C are incorrect because chest physiotherapy is ideally done before meals to optimize its benefits and avoid complications associated with timing.

Correct Answer: C

Rationale: The correct answer is C: Failure to pass meconium and abdominal distension. Hirschsprung's disease is commonly diagnosed in newborns due to the failure to pass meconium within the first 24-48 hours after birth and abdominal distension, indicating a bowel obstruction. Choices A, B, and D are incorrect because they do not correspond to the typical symptoms of Hirschsprung's disease. Acute diarrhea and dehydration, current jelly-like stools and pain, and projectile vomiting with altered electrolytes are not characteristic of this condition.
