Prior to suctioning, the nurse must check suction pressures. Which of the following is the correct pressure range for suctioning?
60-80 mmHg
80-120 mmHg
60-100 mmHg
40-60 mmHg
The Correct Answer is B
Rationale:
A. 60–80 mmHg is too low and may not be effective in clearing secretions.
B. 80–120 mmHg is the correct suction pressure range for infants and children; it is strong enough to remove secretions without causing mucosal trauma.
C. 60–100 mmHg is not the recommended standard range for safe suctioning in pediatric clients.
D. 40–60 mmHg is too low and will not provide adequate suctioning.

Correct Answer is B
Explanation
Rationale:
A. 10–15 seconds; 3 passes is incorrect because 10–15 seconds refers to suctioning duration, not the rest period.
B. Waiting 1–3 minutes between passes allows the patient to reoxygenate and recover. No more than 3 suction passes are recommended to minimize hypoxia and mucosal trauma.
C. 10–15 seconds; 2 passes is incorrect because 10–15 seconds refers to suction time, and limiting to 2 passes is not standard practice.
D. 1–3 minutes; 2 passes is incorrect because up to 3 passes are safe when adequate oxygenation is provided.
Correct Answer is B
Explanation
Rationale:
A. Asking the patient to cough is appropriate if the tube has entered the airway, but it is not the first action when resistance is encountered.
B. Withdrawing the tube to the nasopharynx is the correct action. Resistance usually means the tube has hit an obstruction (e.g., nasal passage, turbinates, or esophagus). Pulling back allows for repositioning and reinsertion without causing trauma.
C. Encouraging the patient to swallow is helpful after the tube has passed the oropharynx but not when resistance is met during early insertion.
D. Hyperextending the neck makes passage into the esophagus more difficult; flexion of the neck is recommended during insertion.
