Correct Answer: D

Rationale: The correct answer is asking the parents to describe the type of pain the child is experiencing because a report of severe colicky abdominal pain in a healthy, thriving child between 3 and 17 months of age is the classic presentation of intussusception. Typical behavior includes screaming and drawing the knees up to the chest. This specific question helps in identifying the key symptom of intussusception. Choices A, B, and C are important aspects of a health history but are not specific to the diagnosis of intussusception. Food allergies, bowel movements, and recent food intake are relevant for a comprehensive assessment but do not directly relate to the specific symptoms of intussusception.

Correct Answer: C

Rationale: Cleft-lip repair is typically performed during the first few months of life to address functional and cosmetic concerns at an early stage. Early repair can enhance bonding and facilitate feeding. While revisions may be necessary later on, addressing the cleft lip early is essential. Option A is incorrect as cleft lip repair is a common surgical procedure. Option B is incorrect as repair is typically done earlier than 6 months for better outcomes. Option D is incorrect as the usual timing for repair is within the first months of life, not between 6 months and 2 years.

Correct Answer: B

Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.

Correct Answer: B

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.

Correct Answer: C

Rationale: The correct answer is providing comfort measures to reduce any crying periods by the child. This can include offering a warm bath, avoiding upright positioning, and using other comfort measures to reduce crying, which can help reduce a hernia. Encouraging coughing or physical activity can increase strain on the hernia. Giving a Fleet enema daily for constipation is not recommended as it can also increase strain on the hernia.
