Question 15

FEV1 Greater than 80% predicted

The patient’s spirometry results indicate intermittent asthma, which typically demonstrates normal lung function between episodes. Therefore, the FEV1 is likely to be greater than 80% predicted, indicating that the patient’s lung function is within normal limits.

A) Greater than 80% predicted

This option is correct as it aligns with the typical spirometry findings in patients with intermittent asthma. During times without exacerbation, patients often exhibit FEV1 values that are at least 80% of the predicted value, reflecting adequate lung function.

B) Between 40-50% predicted

This option is incorrect because an FEV1 between 40-50% predicted would indicate a significant obstruction, which is not typical for a patient with intermittent asthma, especially one who is asymptomatic at the time of assessment.

C) Below 60% predicted

This option is also incorrect for similar reasons. An FEV1 below 60% predicted would suggest severe airway obstruction, which would not be expected in a patient experiencing only intermittent asthma symptoms without any other significant respiratory issues.

D) Between 60-80% predicted

This option is not applicable in this scenario, as it suggests some degree of obstruction. Given that the patient is experiencing intermittent asthma and has no other symptoms, an FEV1 in this range does not accurately reflect the likely spirometry results.

Conclusion

In conclusion, the correct answer is A) Greater than 80% predicted, as it is consistent with normal lung function in individuals with intermittent asthma. Other options suggest varying degrees of obstruction that do not align with the clinical presentation of the patient, who is asymptomatic and has no significant risk factors.
