A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?

A. Treatment is not needed if the client is asymptomatic.

Even asymptomatic pulmonary embolisms can lead to complications such as progression to symptomatic PE or development of chronic thromboembolic pulmonary hypertension. Therefore, treatment is necessary to prevent these complications.

B. Treatment is not needed if the pulmonary embolism is intermediate.

The severity of a pulmonary embolism is determined by various factors, including the size and location of the clot and the degree of obstruction in the pulmonary arteries. Intermediate-risk pulmonary embolisms still require treatment to prevent complications and reduce the risk of progression to a more severe or life-threatening condition.

C. Treatment is not needed if the client is hemodynamically stable.

Hemodynamic stability refers to the client's circulatory status and whether they are maintaining adequate blood flow to vital organs. While hemodynamically stable clients may not require aggressive interventions such as thrombolytic therapy or surgical embolectomy, they still require anticoagulant therapy to prevent further clot formation and reduce the risk of complications.

D. Treatment is needed for all clients who have a pulmonary embolism.

Pulmonary embolism (PE) is a serious and potentially life-threatening condition that requires prompt treatment. Regardless of the severity of symptoms or the client's hemodynamic stability, treatment is necessary to prevent complications and reduce the risk of recurrence. Treatment typically includes anticoagulant therapy to prevent further clot formation and may include additional interventions such as thrombolytic therapy or surgical interventions in certain cases.

A. "You should inhale through your nose and exhale through your mouth during purse-lipped breathing."

Pursed-lip breathing is a breathing technique commonly used by individuals with COPD to help improve breathing efficiency and manage dyspnea (shortness of breath). During purse-lip breathing, the individual inhales slowly through the nose and exhales slowly and gently through pursed lips, creating a slight resistance to the airflow. This technique helps to keep the airways open longer during exhalation, reduces air trapping, and improves oxygenation.

B. "Your inspiration should be longer than expiration during purse-lipped breathing."

Pursed-lip breathing typically involves making both the inspiration and expiration longer than usual. The focus is on slowing down the breathing rate and extending the exhalation phase to promote better gas exchange and reduce respiratory effort.

C. "You should cough forcefully during exhalation when you are purse-lipped breathing."

Pursed-lip breathing is a gentle breathing technique used to promote relaxation and control of breathing. Forceful coughing during exhalation is not part of purse-lip breathing and may not be appropriate, especially for individuals with COPD who are prone to airway irritation and bronchospasm.

D. "You should be flat on your back when you perform purse-lipped breathing."

The position for performing purse-lip breathing is not specific to lying flat on the back. Individuals can perform purse-lip breathing in various positions that are comfortable and allow for effective breathing, such as sitting upright or leaning slightly forward. The key is to find a position that facilitates relaxation and optimal lung expansion.
