A nurse is reinforcing preoperative teaching for a client about coughing and deep breathing. Which of the following statements should the nurse make?
"Repeat your breathing exercise every 2 hrs."
"Inhale through your mouth."
"Hold your breath for 5 seconds."
"Exhale through your nose."
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) Choose a wool blanket when using oxygen. Wool and synthetic fabrics can generate static electricity, which is a fire hazard in the presence of oxygen.
B) Keep oxygen tanks 4 feet away from an electric stove. Oxygen tanks should be kept at least 8 to 10 feet away from heat sources, including electric stoves.
C) Store oxygen tanks upright. Oxygen tanks should always be stored upright and secured to prevent them from falling and causing injury or damage.
D) Use petroleum-based ointments to moisturize lips. Petroleum-based products are flammable and should be avoided when using oxygen. Water-based moisturizers are safer.
Correct Answer is A
Explanation
A. Two deep breaths, then inhale deeply again and force out the air quickly: This technique helps clear mucus by mobilizing it toward the larger airways for expulsion.
B. One deep breath and quickly exhale: This method is less effective in mobilizing secretions compared to multiple preparatory breaths.
C. One breath, hold it for 3 seconds, then forcefully exhale three times with mouth open: Holding the breath promotes mucus loosening, and repeated exhalations help clear secretions. While this technique can be correct in some protocols, it is less common for "forceful" cough instructions and may not be the preferred method.
D. Two breaths and force the air out quickly: Lacks the preparatory deep breath necessary for effective secretion clearance.
