A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?

A. Providing immediate rest for the client: Rest is important, but in the context of an acute asthma exacerbation, addressing the underlying respiratory distress is the priority.

B. Administering a nebulized beta-adrenergic agonist: This is the correct answer. Beta-adrenergic agonists, such as albuterol, are bronchodilators that help relieve bronchoconstriction and improve airflow. Administering a nebulized beta-adrenergic agonist is a key intervention during an acute asthma exacerbation to alleviate symptoms and improve respiratory function.

C. Positioning the client in high-Fowler's: While positioning can assist with respiratory effort, administering a bronchodilator is a more direct and immediate intervention to relieve airway obstruction.

D. Initiating oxygen therapy: While oxygen therapy may be necessary, addressing bronchoconstriction with a beta-adrenergic agonist is the primary intervention during an acute asthma exacerbation.

A."I will follow a daily diet high in calories and protein": While maintaining adequate nutrition is important, emphasizing a diet high in calories may not be suitable. A balanced diet, including adequate protein, is recommended.

B."I will avoid getting a flu shot": Individuals with emphysema are at an increased risk of respiratory infections, including influenza. Getting a flu shot is generally recommended to reduce the risk of infection and complications.

C. "I will inhale slowly through pursed lips to help me breathe better."
This statement reflects a correct understanding of a beneficial breathing technique for individuals with emphysema. Inhaling slowly through pursed lips can help create back pressure in the airways, preventing them from collapsing and promoting better air exchange in the lungs. This technique can assist in managing shortness of breath and improving overall respiratory function.

D."I will lie on my stomach to practice abdominal breathing every day": While practicing abdominal breathing can be beneficial, lying on the stomach may not be the most practical or comfortable position for this purpose. The emphasis should be on proper breathing techniques, which can be done in various positions, including sitting or standing.
