Correct Answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

Correct Answer: B

Rationale: The correct answer is B: Paroxysmal abdominal pain. Colic in infants is characterized by paroxysmal abdominal pain, leading to excessive crying and fussiness. It is not caused by inadequate peristalsis (Choice A), an allergic response to certain proteins in milk (Choice C), or a protective mechanism designed to eliminate foreign proteins (Choice D). Understanding that colic is primarily associated with abdominal pain helps healthcare providers provide appropriate care and support to parents dealing with colicky infants.

Correct Answer: B

Rationale: A lumbar puncture is performed to obtain a sample of cerebrospinal fluid for analysis. This fluid is then examined for signs of infection, bleeding, or other abnormalities. Measuring the pressure of cerebrospinal fluid is typically done during the procedure itself, but it is not the primary purpose of the lumbar puncture. While a lumbar puncture can indirectly help relieve intracranial pressure by removing excess cerebrospinal fluid, this is not its primary purpose. Assessing the presence of infection in the spinal fluid is part of the analysis that follows the collection of the sample, making it a secondary outcome of the procedure.

Correct Answer: B

Rationale: The most important nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention helps to maintain airway patency and improve breathing, which are crucial in managing bronchiolitis. Administering bronchodilators (Choice A) may be a part of the treatment plan but is not the most important intervention. Monitoring oxygen saturation (Choice C) is important but falls secondary to providing direct respiratory support. Encouraging fluid intake (Choice D) is also essential but does not address the immediate respiratory needs of the child with bronchiolitis.

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.
