What is the most important intervention for a nurse to implement for a child with sickle cell anemia admitted to the hospital during a vaso-occlusive crisis?

Correct Answer: B

Rationale: Ensuring adequate hydration is crucial during a vaso-occlusive crisis in sickle cell anemia as it helps to reduce the viscosity of the blood and prevent further sickling of the cells. While administering oxygen may be necessary in some cases, ensuring hydration takes precedence as it directly impacts the underlying pathophysiology of the crisis. Monitoring vital signs is important for ongoing assessment but does not directly address the crisis as hydration does. Administering pain medication is important for pain relief but does not address the primary issue of vaso-occlusion and is not the most crucial intervention in this scenario.

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention for a child experiencing an acute asthma exacerbation. Bronchodilators help to dilate the airways, making breathing easier and relieving acute symptoms of asthma. Antihistamines are not the first-line treatment for asthma exacerbations; they are more commonly used for allergic reactions. Corticosteroids are beneficial in reducing inflammation in asthma but are usually administered after bronchodilators to provide long-term control. Oxygen therapy may be necessary in severe cases of asthma exacerbation, but bronchodilators take precedence in improving airway patency and respiratory distress.

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, indicating irritation of the meninges. Rash (Choice A) is not typically associated with bacterial meningitis. Photophobia (Choice B) can be present but is more commonly seen in viral meningitis. Jaundice (Choice C) is not a typical clinical manifestation of meningitis and is more indicative of liver dysfunction.

Correct Answer: D

Rationale: At 10 months of age, pulling to a stand is a developmental milestone that most infants can achieve. Crawling typically occurs around 6-9 months, sitting without support around 6-8 months, and standing with assistance around 7-11 months. Therefore, choices A, B, and C are not the expected developmental milestones for a 10-month-old infant.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is crucial for ensuring the child's safety during a seizure. Keeping a diary of seizure activity (choice A) is important for tracking patterns and triggers but does not directly relate to immediate safety during a seizure. Administering antiepileptic medication only when a seizure occurs (choice B) is incorrect as medications should be given as prescribed to maintain therapeutic levels. Restricting the child's activities to prevent seizures (choice C) is not an appropriate approach as it may limit the child's quality of life without guaranteeing seizure prevention.
