A school-age child is admitted to the pediatric unit with a vaso-occlusive crisis. Which of these should be included in the nursing plan of care?
- A. Correction of alkalosis
- B. Pain management and administration of heparin
- C. Adequate oxygenation and replacement of factor VIII to correct the sickling
- D. Adequate hydration, oxygenation, and pain management
Correct Answer: D
Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia require a comprehensive approach that includes adequate hydration to reduce blood viscosity, oxygenation to prevent further sickling of red blood cells, and aggressive pain management. This approach helps improve tissue perfusion and manage pain effectively. Choices A, B, and C are incorrect. Correction of alkalosis is not a priority in vaso-occlusive crisis management. Administration of heparin is not indicated as it can increase the risk of bleeding in sickle cell patients. Factor VIII replacement is not relevant to sickle cell anemia as it is a treatment for hemophilia, not sickle cell disease.
A nurse is carrying on a conversation with a 7-year-old child during an office visit. Which is an example of the level of language development the nurse should expect in this child?
- A. Fascination with bathroom language
- B. Difficulty understanding the concept of 'half past' in reference to time
- C. Ability to carry on an adult conversation
- D. Inability to speak in full sentences
Correct Answer: B
Rationale: The correct answer is B. Understanding time concepts like 'half past' can be challenging for a 7-year-old, indicating the level of language development. Choice A is incorrect as fascination with bathroom language is common in this age group but not necessarily indicative of language development. Choice C is incorrect as a 7-year-old typically cannot carry on an adult conversation due to cognitive and experiential limitations. Choice D is incorrect as by the age of 7, children should be able to speak in full sentences.
Pretending a sheet is a cape to mimic a superhero is characteristic of which childhood phenomenon?
- A. Artificialism
- B. Symbolic functioning
- C. Critical thinking
- D. Dramatic play
Correct Answer: B
Rationale: The correct answer is B, symbolic functioning. Symbolic functioning refers to children using objects, actions, or ideas to represent other objects, actions, or ideas. In this scenario, pretending a sheet is a cape to mimic a superhero demonstrates the child's ability to engage in symbolic play. Choice A, artificialism, is incorrect as it refers to the belief that inanimate objects have lifelike qualities. Choice C, critical thinking, does not directly relate to the imaginative play described in the question. Choice D, dramatic play, is close but not as precise as symbolic functioning, which specifically highlights the use of objects to represent something else.
The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?
- A. Respiratory syncytial virus (RSV)
- B. Haemophilus influenzae
- C. Parainfluenza
- D. Rotavirus
Correct Answer: A
Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.
