CRITICAL CARE HESI EXAMINATION TEST 2026
FULL QUESTIONS AND VERIFIED SOLUTIONS
◉ HESI Hint Suctioning Answer: Do not routinely suction; Suction
only when secretions are present
◉ HESI Hint Allen test Answer: Before drawing a sample for ABGs
from the radial artery, perform the Allen test to assess collateral
circulation.
The Allen test ensures collateral circulation to the hand if
thrombosis of the radial artery should follow the puncture.
◉ Respiratory Failure in Children Causes Answer: A. Congenital
heart disease.
B. Respiratory distress syndrome.
C. Infection, sepsis.
D. Neuromuscular diseases.
E. Trauma and burns.
F. Aspiration.
G. Fluid overload and dehydration.
H. Anesthesia and narcotic overdose
, ◉ Nursing Assessment: Respiratory Failure in Children Answer: A.
Very slow or very rapid respiratory rate (tachypnea), dyspnea,
apnea, gasping, stridor.
B. Tachycardia.
C. Cyanosis, pallor, or mottled color (connotes deterioration of
systemic perfusion).
D. Irritability and later, lethargy (connotes a deteriorating LOC).
E. Retractions, nasal flaring, poor air movement.
F. Hypoxemia, hypercapnia, respiratory acidosis.
G. Lab data: values should be evaluated, keeping in mind the
percentage of oxygen the child is receiving.
◉ HESI Hint Resp Failure in children Answer: Cardinal signs of Acute
Respiratory Failure in children are restlessness, tachypnea,
tachycardia, and diaphoresis
◉ HESI Hint ABG resp failure in children Answer: PCO2>45 or
PO2<60 on 50% O2 signifies respiratory failure. A child in severe
distress should be on 100% O2.
◉ What PO2 value indicates respiratory failure in adults? Answer:
PO2 below 60 mmHg
