If the patient has good control of her asthma, her peak flow rate is in the _________

Q: Which peak flow zone indicates that large airways are beginning to narrow?

Yellow. This means caution” or slow down.” The yellow zone is 50% to 80% of your personal best. Measurements in this zone are a sign that your large airways are starting to narrow.

Q: Which of the following would you include in the patient teaching for a patient with a Holter monitor?

which of the following would be included in the patients instructions regarding Holter monitor test? Instruct the patient to record all activities, emotions, symptoms, and medications taken.

Which peak flow zone indicates that large airways are beginning to narrow?

Yellow. This means “caution” or “slow down.” The yellow zone is 50% to 80% of your personal best. Measurements in this zone are a sign that your large airways are starting to narrow.

Which of the following measures and evaluate the patient's lung capacity and volume?

The most basic test is spirometry. This test measures the amount of air the lungs can hold. The test also measures how forcefully one can empty air from the lungs. Spirometry is used to screen for diseases that affect lung volumes.

Which of the following would you include in the patient teaching for a patient with a Holter monitor?

which of the following would be included in the patient's instructions regarding Holter monitor test? Instruct the patient to record all activities, emotions, symptoms, and medications taken.
