Which developmental consideration is most important when preparing a school-age child (6-12 years) for IV insertion?
Answer: Providing a simple, honest explanation of what to expect
School-age children benefit most from a simple, honest explanation of what to expect during IV insertion. At this developmental stage, children can understand cause and effect and cope better when they feel informed and involved. Deception or lack of information increases anxiety and distrust.
A premature infant is receiving IV fluids at 4 mL/hr. The nurse notices the infusion pump has been running at 40 mL/hr for 30 minutes. What is the excess volume infused?
Answer: 18 mL
The excess volume is calculated by subtracting the intended volume from the actual volume delivered. Actual: 40 mL/hr × 0.5 hr = 20 mL. Intended: 4 mL/hr × 0.5 hr = 2 mL. Excess: 20 - 2 = 18 mL. In a premature infant, this excess could be life-threatening.
Which electrolyte imbalance is most common in pediatric patients receiving large volumes of normal saline (0.9% NaCl)?
Answer: Hyperchloremic metabolic acidosis
Hyperchloremic metabolic acidosis is the most common electrolyte imbalance from large-volume normal saline infusion. Normal saline contains 154 mEq/L of chloride, which is higher than physiologic levels. Excessive chloride causes a non-anion gap metabolic acidosis, particularly problematic in pediatric patients.
What is the appropriate action when a pediatric patient's IV site shows a grade 2 infiltration on the INS scale?
Answer: Discontinue the IV and elevate the extremity
A grade 2 infiltration (slight swelling, cool to touch, with or without blanching) requires immediate discontinuation of the IV and elevation of the affected extremity. Continuing the infusion at any rate would worsen tissue damage. A new IV site should be selected.
Which blood product requires a specific filter for administration in pediatric patients?
Answer: All cellular blood products through a standard 170-260 micron filter
All cellular blood products (red blood cells, platelets, whole blood) must be administered through a standard 170-260 micron blood filter to remove clots and debris. This requirement applies equally to pediatric and adult patients and is a fundamental safety standard for transfusion therapy.
A 5-year-old requires IV potassium chloride supplementation. What is the maximum recommended concentration for peripheral IV administration?
Answer: 40 mEq/L
The maximum recommended concentration of potassium chloride for peripheral IV administration in pediatric patients is 40 mEq/L. Higher concentrations are vesicants that can cause severe phlebitis, pain, and tissue necrosis if infiltration occurs. Concentrations above 40 mEq/L require central venous access.
