An infant with bronchiolitis is hospitalized. The causative organism is RSV. The nurse knows that a child infected with this virus requires the following isolation:

A. Ridiculing their fears so they understand that there is no need to be afraid.

This option is not recommended. Ridiculing a child's fears can be emotionally harmful and may lead to increased anxiety. It's important to approach fears with empathy and support.

B. Using logical persuasion to explain away their fears and help them recognize how unrealistic the fears are.

While providing information and reassurance is important, simply dismissing or explaining away a child's fears may not be sufficient. Preschoolers may need more concrete strategies and involvement in managing their fears.

C. Actively involving them in finding practical methods to deal with the frightening experience.

This is the recommended choice. Actively involving preschoolers in finding practical methods allows them to participate in the process, promoting a sense of control and autonomy. It encourages them to develop coping skills.

D. Forcing them to confront the frightening object or experience in the presence of their parents.

Forcing a child to confront their fears may intensify anxiety and is generally not a recommended approach. It's essential to respect a child's pace and provide support as they work through their fears.

A. Peak expiratory flow meter:

- A peak expiratory flow meter is a device used to measure how fast a person can exhale. It is commonly used to monitor and manage asthma by assessing the degree of airway obstruction. Regular use can help determine how well asthma is controlled and whether changes in the management plan are needed.

B. Inhaled steroids:

- Inhaled steroids are a type of long-term control medication used to manage asthma by reducing inflammation in the airways. While these are essential for controlling symptoms, they do not directly assess how well the asthma is currently controlled.

C. Metered dose inhaler with spacer:

- A metered dose inhaler (MDI) with a spacer is a device used to deliver medication directly to the lungs. While it is a crucial part of asthma management, it does not directly measure how well the asthma is controlled.

D. Pulse oximetry:

- Pulse oximetry measures the oxygen saturation in the blood and is useful in assessing respiratory status. However, it is not specific to asthma control and may not provide a comprehensive picture of asthma management.
