A child has a continuous intravenous infusion. How frequently should the nurse assess a child's intravenous infusion site?
Every three hours
Every hour
Every four hours
Every two hours
The Correct Answer is B
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.

Correct Answer is C
Explanation
Pharmacokinetics in neonates is influenced by developmental physiology affecting drug absorption, distribution, metabolism, and excretion, resulting in altered serum concentrations and increased susceptibility to toxicity or therapeutic variability clinically significant.
Rationale:
A. Increased hydrochloric acid secretion is physiologically decreased in infants. This reduces gastric acidity affecting drug absorption patterns overall significantly. This is incorrect because infants have immature gastric secretion systems function. Pharmacokinetic effect mainly impacts oral weak acid drugs absorption variability.
B. Hepatic metabolism in infants is slower due immature enzymes activity. Drug clearance is reduced leading to prolonged half life duration. Liver enzyme systems CYP450 systems are underdeveloped in neonates significantly immature.
C. Renal function in infants is immature with reduced glomerular filtration. This leads to decreased clearance and drug accumulation risk increased. Tubular secretion and reabsorption mechanisms are not fully developed functions. Major determinant of neonatal pharmacokinetic variability in drug dosing regimens.
D. Intestinal transit in infants is variable and not consistently slower. Absorption depends more on pH and enzyme immaturity status. Motility patterns differ across neonates making prediction unreliable clinically variable. This factor is less significant than renal drug elimination process.
Correct Answer is C
Explanation
Toddlers experience separation anxiety, limited cognitive understanding of time, and heightened fear of bodily harm during hospitalization. Painful procedures should be structured to reduce environmental associations with routine care areas and minimize anticipatory distress and procedural conditioning.
Rationale:
A. Telling the child the procedure will not hurt is inappropriate because toddlers rely on concrete thinking and quickly learn to distrust caregivers if pain occurs. This increases anxiety and reduces future cooperation with healthcare providers.
B. Having the parent leave increases separation anxiety, which is already a major stressor in toddlers. Parental presence provides security and reduces distress during painful procedures, improving cooperation and emotional regulation.
C. Performing painful procedures in a separate treatment room helps prevent negative environmental association with the child’s room. This reduces conditioned fear responses and allows the child to perceive the bedside space as safe and comforting.
D. Telling a toddler the day before is ineffective due to limited time perception. Toddlers cannot meaningfully process delayed events, leading to prolonged anxiety without improving understanding or cooperation during the actual procedure.
