The nurse is caring for a 3 week old infant with a surgical incision. Which of the following pain scales is appropriate for assessing her pain?

Peripheral intravenous therapy in pediatric patients requires frequent monitoring due to higher risk of infiltration, phlebitis, infection, and fluid overload. Children have smaller and more fragile veins, making IV sites more prone to rapid deterioration and complications. Continuous infusions demand close surveillance to ensure patency and prevent tissue injury or systemic complications.

Rationale:

A. This interval is too prolonged for pediatric IV monitoring. Delayed assessment increases risk of unrecognized infiltration or extravasation, which can rapidly cause tissue damage in children due to small vessel size and limited subcutaneous space.

B. Pediatric continuous IV infusions require hourly site assessment to detect early signs of infiltration, phlebitis, or dislodgement. Frequent monitoring ensures immediate intervention, minimizing complications and maintaining safe vascular access.

C. This frequency is appropriate for stable adult IV sites but unsafe in pediatrics. Extended intervals increase risk of missed complications, especially with continuous infusions where tissue damage can progress quickly in children.

D. Although closer to acceptable practice, this interval is still insufficient for high-risk pediatric infusions. Early detection of complications is critical, and standard pediatric protocols favor more frequent hourly assessments.

Oral drug absorption in young children is determined by developmental differences in gastrointestinal motility, gastric emptying, intestinal enzyme activity, and mucosal surface maturation. In children under 5 years, accelerated and irregular intestinal transit can significantly disrupt the designed pharmacokinetics of extended-release formulations, reducing consistent drug absorption and therapeutic effect.

Rationale:

A. Constipation increases intestinal transit time, which may prolong drug contact with absorptive surfaces and potentially enhance absorption. It does not interfere with the controlled-release mechanism of time-released formulations in children under 5 years.

B. Renal immaturity affects drug excretion and clearance rather than gastrointestinal absorption. Time-release oral medications depend on gastrointestinal transit dynamics, not renal function, making this option unrelated to the absorption issue.

C. Children under 5 have rapid peristalsis and shortened intestinal transit time, reducing controlled drug release and absorption window. This disrupts extended-release formulation kinetics, leading to incomplete or inconsistent systemic drug levels.

D. Reduced gastric acid affects dissolution of acid-dependent drugs but does not significantly impair extended-release medication absorption. Time-release systems are primarily designed for intestinal release, so this factor has minimal impact on overall absorption in this age group.
