A nurse is providing teaching to a client who has a new diagnosis of fibromyalgia. Which of the following client statements indicates an understanding of the teaching?

Choice A rationale:
Coughing and deep breathing: These techniques directly promote airway clearance by mobilizing and expelling secretions from the lungs. They are essential for clients with pneumonia, as the buildup of secretions can obstruct the airways and impair gas exchange.
Hydration maintenance: Adequate hydration helps to thin secretions, making them easier to cough up and clear from the lungs. It also helps to prevent dehydration, which can worsen respiratory symptoms.

Choice B rationale:
Keeping the head of the bed elevated: This can help to improve breathing by decreasing the work of breathing and promoting lung expansion. However, it is not the most effective intervention for directly clearing secretions from the lungs.

Choice C rationale:
Preparation for insertion of a tracheostomy tube: This is a more invasive intervention that may be necessary in severe cases of airway obstruction. However, it is not the priority intervention for a client with ineffective airway clearance related to pneumonia.

Choice D rationale:
Providing supplemental oxygen: This can help to improve oxygenation in clients with pneumonia. However, it does not directly address the problem of ineffective airway clearance.

Rationale for Choice A:
Phenytoin is an anticonvulsant medication used to control seizures. It is typically a long-term medication, and abruptly stopping it can lead to breakthrough seizures or worsen existing seizures.
This statement indicates that the client may not understand the importance of taking phenytoin consistently and the potential consequences of discontinuing it without consulting their doctor.

Rationale for Choice B:
Making an appointment with a dentist is important for all individuals, including those with seizure disorders. There is no specific concern related to phenytoin and dental care that would necessitate further teaching in this context.

Rationale for Choice C:
It is important for clients to understand that switching brands of phenytoin might affect its effectiveness due to slight variations in formulation. However, simply stating awareness of this fact does not necessarily indicate a need for further teaching, as the nurse can assess the client's understanding through further questioning.

Rationale for Choice D:
Notifying a doctor before taking any new medications is crucial for individuals with seizures, as some medications can interact with phenytoin and increase the risk of seizures. This statement demonstrates the client's understanding of an important safety precaution.
Therefore, Choice A is the only statement that suggests a potential lack of understanding about the long-term nature of phenytoin treatment and the dangers of discontinuing it without medical supervision. This highlights the need for further education to ensure the client's safety and adherence to the prescribed medication regimen.
