Read the first 6 IV Therapy in Special Populations flashcards as text

  1. Which site is preferred for intraosseous (IO) access in emergency situations when IV access is unobtainable in a child?

    Answer: Proximal tibia

    The proximal tibia is the preferred IO access site in children because it is easily identified, has a flat surface, and is distant from the chest during CPR.

  2. A patient receiving chemotherapy develops extravasation of doxorubicin (an anthracycline vesicant). Which antidote is indicated?

    Answer: Dexrazoxane (Totect)

    Dexrazoxane (Totect) is the FDA-approved antidote for anthracycline extravasation, working by inhibiting free radical-mediated tissue damage.

  3. Why should IV medications be administered cautiously in patients with chronic kidney disease (CKD)?

    Answer: Impaired renal clearance leads to drug accumulation and increased risk of toxicity

    CKD impairs renal drug clearance, causing renally-cleared medications to accumulate to toxic levels if doses are not adjusted.

  4. In a pregnant patient requiring IV therapy, which solution is recommended to avoid to prevent fetal harm?

    Answer: Large volumes of hypotonic solutions like 0.45% NaCl administered rapidly

    Rapid large-volume hypotonic IV fluid administration in pregnancy can cause maternal hyponatremia and neonatal hyponatremia/cerebral edema.

  5. When managing IV therapy for an obese patient, which catheter-related challenge is most commonly encountered?

    Answer: Difficulty visualizing and palpating veins due to adipose tissue, often requiring ultrasound guidance

    Subcutaneous adipose tissue in obese patients obscures vein visualization and palpation; ultrasound guidance significantly improves first-attempt success rates.

  6. Which precaution is most important when administering IV potassium chloride to a pediatric patient?

    Answer: Never exceed recommended infusion rates and verify concentration limits to prevent cardiac arrest

    IV potassium must be administered as a dilute solution at controlled rates because rapid or concentrated potassium infusion can cause fatal cardiac arrhythmias.
