PALS Vascular Access and Fluid Management in Pediatric Emergencies

Question 1

When peripheral IV access cannot be established quickly in a critically ill child, what is the recommended alternative route for emergency medication administration?

Accepted Answer

Intraosseous (IO) access

Answer

IO access is recommended by PALS guidelines when IV access cannot be established rapidly, as it provides reliable vascular access in emergencies.

Question 2

Which is the preferred IO insertion site in infants and young children?

Accepted Answer

Proximal tibia, 1–3 cm below the tibial tuberosity

Answer

The proximal tibia is the preferred IO site in young children due to its flat, easily identifiable surface and large medullary cavity.

Question 3

A 10 kg child in septic shock requires a fluid bolus. What is the correct isotonic fluid dose per PALS guidelines?

Accepted Answer

10–20 mL/kg of isotonic crystalloid over 10–20 minutes

Answer

PALS recommends 10–20 mL/kg boluses of isotonic crystalloid (normal saline or lactated Ringer's) for pediatric shock, reassessing after each bolus.

Question 4

After administering 60 mL/kg of isotonic fluid to a child in septic shock with no improvement, what medication should be started?

Accepted Answer

Vasoactive agents such as epinephrine or norepinephrine

Answer

If a child remains in shock after 40–60 mL/kg of fluid resuscitation, vasoactive/inotropic support should be initiated.

Question 5

Which finding best indicates that a fluid bolus has been successful in a child with hypovolemic shock?

Accepted Answer

Improved capillary refill, improved mental status, and normalization of heart rate

Answer

Successful fluid resuscitation is indicated by improved perfusion signs: better capillary refill, improved mentation, and normalization of heart rate.
