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: C

Rationale: In this scenario, the nurse failed to report or document the slow respiratory rate of the infant, which later led to severe respiratory distress. It is crucial to understand that any vital signs outside the expected range in an infant should be documented and reported promptly. This documentation is vital for monitoring the infant's condition, identifying potential issues, and ensuring timely intervention if needed. Choices A, B, and D are incorrect because they downplay the significance of abnormal vital signs and fail to emphasize the importance of documentation and reporting in infant care.

Correct Answer: D

Rationale: The Resiliency model of family stress, adjustment, and adaptation is the appropriate theory in this scenario. This model focuses on identifying risks and protective factors that help families achieve positive outcomes despite challenges. Duvall's developmental theory primarily focuses on family life cycle stages, Friedman's structural functional theory emphasizes the interdependence of family members, and Von Bertalanffy's general system theory applied to families looks at the family as a dynamic system. These theories do not specifically address the concept of resilience and adaptation in the face of stressors like homelessness.

Correct Answer: B

Rationale: The correct answer is to monitor for signs of dehydration. After treatment for dehydration, it is crucial to educate caregivers about recognizing early signs of dehydration to prevent its recurrence. Monitoring for dehydration ensures that appropriate measures can be taken promptly if signs reappear. Choices A, C, and D are incorrect because infection, hypovolemia, and malnutrition, while important considerations in healthcare, are not the primary focus after treating dehydration in a 3-year-old child.

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.
