Answer:
Intraosseous
Step-by-step explanation:
Intraosseous administration is preferred in infants and toddlers who have poor vascular access in an emergent situation. It is preferred when intravenous (IV) access is impossible. Intrathecal administration is preferred when long-term medication administration is required. The medication will be directly administered into the pleural space when intrapleural administration is performed. Chemotherapeutic medications are commonly administered through this route. Chemotherapeutic agents, insulin, and antibiotics are administered through the intraperitoneal route.
