Kettering NPS Questions And Answers 100% All Verified Solution
Question 1: An infant born to a mother who smoked cigarettes
during pregnancy is at a greater risk of
a) Central nervous system dysfunction
b) Intrauterine growth retardation
c) Teratogenic effects
d) Lower intellectual level
CORRECT ANSWER : b) Intrauterine growth retardation
Rationale: Maternal smoking during pregnancy is strongly
associated with intrauterine growth retardation (IUGR), leading to low birth weight and preterm birth. Central nervous system dysfunction and teratogenic effects are more linked to alcohol consumption, while lower intellectual level is associated with maternal malnutrition or diabetes.
Question 2: Which of the following suction catheters would be
most appropriate to use for a pediatric patient with a size 6 mm
ID ETT?
- 6 Fr
- 8 Fr
- | Page
- 10 Fr
- 12 Fr
CORRECT ANSWER : b) 8 Fr
Rationale: The appropriate suction catheter size for an
endotracheal tube (ETT) is typically about half the internal diameter of the ETT in millimeters, converted to French (Fr) units. For a 6 mm ID ETT, an 8 Fr catheter is suitable as it ensures effective suctioning without occluding the tube.
Question 3: While suctioning a 10-year old child receiving
mechanical ventilation, the neonatal/pediatric specialist is unable to pass the suction catheter through the ETT. The specialist should
a) Attempt to insert a smaller catheter
b) Increase the suction pressure
c) Remove and replace the ETT
d) Deflate and reinflate the ETT cuff
CORRECT ANSWER : c) Remove and replace the ETT

Rationale: Inability to pass the suction catheter indicates an
obstruction in the ETT, constituting an airway emergency.Removing and replacing the ETT is the most definitive action to restore airway patency.
Question 4: The neonatal/pediatric specialist is preparing to
extubate a 14-year old patient who required mechanical ventilation because of a severe exacerbation of asthma. The specialist has obtained the equipment necessary for the procedure. In what sequence should the specialist perform the procedure?
a) Suction the airway, deflate the cuff, encourage the patient to
cough, remove the tube during exhalation, observe the patient for complications, and administer oxygen
b) Suction the airway, deflate the cuff, remove the tube at peak
inspiration, encourage the patient to cough, administer oxygen, and observe the patient for complications
c) Deflate the cuff, suction the airway, remove the tube while
suctioning, encourage the patient to cough, administer oxygen, and observe the patient for complications
d) Deflate the cuff, suction the airway, remove the tube at peak
inspiration, encourage the patient to cough, and observe

CORRECT ANSWER : b) Suction the airway, deflate the cuff,
remove the tube at peak inspiration, encourage the patient to cough, administer oxygen, and observe the patient for complications
Rationale: The correct sequence involves suctioning first to
clear secretions, deflating the cuff to allow tube removal, removing the tube at peak inspiration to maximize airway clearance, encouraging a cough to expel residual secretions, administering oxygen to support oxygenation, and observing for complications.
Question 5: The pediatric pulmonologist is preparing to intubate
a child with laryngotracheal stenosis. Which of the following devices would be most appropriate for this potentially difficult intubation?
