Correct Answer: B

Rationale: It is recommended that a child should visit the dentist within the next few months after turning two years old. This allows for early dental check-ups to monitor oral health, detect any issues early on, and establish a good oral hygiene routine. Choice A ('Before starting school') is not as specific and may delay the child's first dental visit. Choice C ('When the first deciduous teeth are lost') is too late for the first dental visit, as preventive care should start earlier. Choice D ('At the next dental visit of a family member') is not ideal as the child's dental needs should be addressed independently of family members' visits.

Correct Answer: B

Rationale: In a pediatric patient presenting with altered mental status, high fever, and a generalized rash, seizures are a significant concern. Febrile seizures can occur in children with high fevers and may lead to further complications. It is crucial to monitor for seizures and be prepared to manage them promptly. Vomiting, combativeness, and respiratory distress are also important considerations in pediatric patients; however, given the clinical presentation described, seizures take priority as they are a common complication in this scenario.

Correct Answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.

Correct Answer: C

Rationale: The correct answer is C. Needing assistance to climb stairs is considered expected behavior for an 18-month-old toddler. At this age, children are still developing their gross motor skills, coordination, and balance, which can vary in proficiency. It is common for toddlers to be able to crawl upstairs before mastering the skill of climbing stairs upright. Options A, B, and D are incorrect because at 18 months, it is normal for children to require help and practice with climbing stairs and does not necessarily point to any specific medical conditions or developmental issues.

Correct Answer: A

Rationale: The correct answer is to monitor for signs of infection. When a child is undergoing chemotherapy, their immune system is compromised, making them more susceptible to infections. Monitoring for signs of infection is crucial to promptly identify and treat any potential infections. Choices B, C, and D are incorrect because although monitoring for bleeding, dehydration, and pain are important aspects of care, the priority for a child receiving chemotherapy is to prevent and detect infections due to their increased vulnerability.
