The nurse clarifies that the condition in which there is a decreased amount of oxygen in the blood is:

A) "Repeat your breathing exercise every 2 hrs." Repeating breathing exercises should be done a couple of times every hour to help prevent postoperative complications such as atelectasis and pneumonia.
B) "Inhale through your mouth." Clients should inhale through their nose to filter, warm, and humidify the air.
C) "Hold your breath for 5 seconds." Holding the breath for 5 seconds allows for better lung expansion and optimal oxygen exchange.
D) "Exhale through your nose." Clients are generally advised to exhale through pursed lips to create positive airway pressure and prevent airway collapse.

A) Secure the tracheostomy ties so that fingers cannot fit between the ties and the neck. The ties should be secure but loose enough to fit one finger between the ties and the neck to prevent skin breakdown and maintain comfort.
B) Suction for 20 seconds. Suctioning for 20 seconds is too long and may cause hypoxia. Suction should not exceed 5 to 10 seconds.
C) Clean secretions from the tube using hydrogen peroxide. Hydrogen peroxide can irritate the delicate tissues and is not recommended. Saline or prescribed cleaning agents are preferred.
D) Set the vacuum pressure at 120 mmHg for suctioning. For a toddler, suction pressure should typically be between 80 and 120 mmHg to prevent mucosal damage.
