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. Saving the sputum specimen in a clean container.

While it is important to collect the sputum specimen in a clean, sterile container, simply saving the specimen in a clean container is not sufficient. The nurse needs to actively collect the sputum specimen from the client using proper technique to ensure that it is not contaminated and is suitable for laboratory analysis.

B. Collecting the sputum specimen after a meal.

Collecting a sputum specimen after a meal is not recommended, as it can increase the likelihood of contamination with food particles. It's preferable to collect the specimen before meals or at least 1-2 hours after eating to minimize the risk of contamination and ensure the integrity of the specimen.

C. Rinse the client's mouth before collecting the specimen.

When obtaining a sputum specimen from a client, it's important for the nurse to plan to rinse the client's mouth before collecting the specimen. Rinsing the mouth with water helps to clear any food particles or debris from the oral cavity, ensuring that the sputum sample collected is not contaminated with saliva or food particles. This improves the quality and accuracy of the specimen for laboratory analysis.

D. Obtaining the specimen from the client in the evening.

The timing of specimen collection is not necessarily restricted to the evening. The timing may vary depending on the client's condition and the healthcare provider's orders. It's important to follow the healthcare provider's instructions regarding the timing of specimen collection, which may be based on factors such as the client's symptoms and the diagnostic requirements.

A. Turn off the ventilator alarms before suctioning the client's airway.

This choice is incorrect because it goes against standard practice. Ventilator alarms are critical for monitoring the patient's respiratory status and detecting any issues with the ventilator or the patient's airway. Turning off alarms before suctioning can lead to missed alarms and potentially dangerous situations for the patient.

B. Provide mouth care every 10 to 12 hr with hydrogen peroxide.

This choice is incorrect because using hydrogen peroxide for mouth care is not recommended. Hydrogen peroxide can be irritating to the mucosa and may cause harm to the patient's oral tissues. Instead, gentle oral care with an appropriate solution, such as a mouthwash specifically designed for oral hygiene in ventilated patients, is preferred. Mouth care should also be provided more frequently than every 10 to 12 hours to maintain oral hygiene and prevent complications such as ventilator-associated pneumonia.

C. Place the head of the client's bed at 40° when supine.

This choice is correct. Proper positioning of the patient is crucial for optimizing ventilation and preventing complications such as aspiration and ventilator-associated pneumonia. Elevating the head of the bed to 40 degrees when the patient is in a supine position helps to minimize the risk of aspiration by promoting drainage of secretions away from the airway and improving lung expansion.

D. Reposition the client every 4 hr.

This choice is not directly related to care for clients receiving mechanical ventilation. While repositioning the patient every 4 hours is important for preventing pressure ulcers and maintaining skin integrity, it is not specific to mechanical ventilation care. However, it is still an important aspect of overall patient care, particularly for patients who are immobile or confined to bed for extended periods.
