The instructor is educating a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?
- A. Myelination continues into adolescence.
- B. The process occurs in a head-to-toe fashion.
- C. Myelination speeds up nerve impulses.
- D. Myelination increases the specificity and efficiency of nerve impulses.
Correct Answer: B
Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.

Why does a cleft lip predispose an infant to infection?
- A. Waste products accumulate along the defect.
- B. There is evidence of inadequate circulation in the defective area.
- C. Nutrition is inadequate due to ineffective feeding.
- D. Mouth breathing dries the oropharyngeal mucous membranes.
Correct Answer: D
Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.
A 13-year-old girl tells the nurse at the pediatric clinic that she took a pregnancy test and it was positive. She adds that her grandfather, with whom she, her younger sisters, and her mother live, has repeatedly molested her for the past 3 years. When the nurse asks the girl if she has told this to anyone, she replies, 'Yes, but my mother doesn't believe me.' Legally, who should the nurse notify?
- A. Police regarding a potential sex crime
- B. Health care provider to confirm the pregnancy
- C. Child Protective Services for immediate intervention
- D. The girl's mother about the positive pregnancy test result
Correct Answer: C
Rationale: In cases of child abuse and ongoing molestation, as described in the scenario, the primary concern is the safety and well-being of the child. Child Protective Services should be notified immediately for intervention to protect the girl and other children in the household from further harm. The police may be involved later to investigate the criminal aspect of the abuse. Notifying the healthcare provider solely to confirm the pregnancy or informing the girl's mother about the positive test result does not address the urgent need for intervention and protection from abuse. Child Protective Services are trained to handle such cases and provide the necessary support and protection for the child and other vulnerable individuals in the family. Immediate action is crucial to ensure the girl's safety and prevent further harm.
A 7-year-old child with a history of seizures is being discharged from the hospital. What should the nurse include in the discharge teaching for the parents?
- A. Administer antiepileptic medication as prescribed, not just when a seizure occurs
- B. Ensure the child gets adequate sleep
- C. Restrict the child's activities to prevent seizures
- D. Teach seizure first aid to family members
Correct Answer: D
Rationale: The correct answer is to teach seizure first aid to family members. This is crucial because family members need to know how to appropriately respond during a seizure to ensure the child's safety. Choice A has been corrected to emphasize that antiepileptic medication should be administered as prescribed, not just when a seizure occurs, to effectively manage the condition. Choice B, while important for overall health, is not directly related to seizure management. Choice C is not recommended as restricting activities may not prevent seizures and may hinder the child's quality of life.
While waiting for the administration of air pressure to reduce the intussusception, the boy passes a normal brown stool. Which nursing action is the most appropriate for the nurse to take?
- A. notify the practitioner
- B. measure abdominal girth
- C. auscultate for bowel sounds
- D. take vital signs, including blood pressure
Correct Answer: A
Rationale: The correct answer is to notify the practitioner. The passage of a normal brown stool in a child with intussusception could indicate spontaneous reduction of the intussusception. It is crucial to inform the practitioner immediately so that they can reassess the situation and determine the next steps, which may include adjusting the planned intervention. Measuring abdominal girth (choice B) may be important in assessing for abdominal distension but is not the most immediate action required in this scenario. Auscultating for bowel sounds (choice C) is a routine nursing assessment but does not take precedence over notifying the practitioner in this critical situation. Taking vital signs, including blood pressure (choice D), is also important but notifying the practitioner is more urgent to address the unexpected change in the patient's condition.
A 6-month-old infant is diagnosed with cystic fibrosis. What explanation should the nurse provide to the parents about this condition?
- A. It is a condition affecting the respiratory and digestive systems.
- B. It is an autoimmune disorder affecting multiple organs.
- C. It is a genetic disorder that can be managed with medication.
- D. It is a condition caused by prenatal exposure to toxins.
Correct Answer: A
Rationale: The correct answer is A: 'It is a condition affecting the respiratory and digestive systems.' Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It is caused by a defective gene that leads to the production of thick and sticky mucus in these organs. This mucus can clog airways in the lungs and block the ducts in the pancreas, affecting digestion. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder; it is a genetic condition. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but merely managing it with medication oversimplifies the comprehensive care needed for individuals with cystic fibrosis. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but is a genetic condition inherited from parents.
