Final answer:
The correct statement is 'I can use my albuterol inhaler if it's absolutely necessary.'
Step-by-step explanation:
The correct statement indicating that the nurse's teaching has been effective is option c: I can use my albuterol inhaler if it's absolutely necessary.
This statement demonstrates that the client has understood the importance of using the inhaler when needed for symptom relief. The use of albuterol inhalers is a common and effective treatment for asthma, and the client's understanding of when and how to use it shows that the nurse's teaching has been successful.
Unlike options a, b, and d, which are not accurate, Option c aligns with the nurse's teaching and best reflects the client's understanding of managing her asthma during pregnancy.
