The nurse is caring for a patient with asthma who has a baseline peak flow reading of 600 mL and calls the nurse, stating that the current peak flow is 420 mL. Which of the following actions should the nurse take first?
- A. Tell the patient to go to the hospital emergency department.
- B. Instruct the patient to use the prescribed salbutamol.
- C. Ask about recent exposure to any new allergens or asthma triggers.
- D. Question the patient about use of the prescribed inhaled corticosteroids.
Correct Answer: B
Rationale: The patient's peak flow is 70% of normal, in the yellow zone, indicating a need for immediate use of short-acting β-adrenergic (SABA) medications. Assessing for correct use of medications or exposure to allergens also is appropriate, but would not address the current decrease in peak flow. Because the patient is currently in the yellow zone, hospitalization is not needed.

Which of the following information should the nurse include in teaching a patient with chronic obstructive pulmonary disease (COPD) who has a new prescription for home oxygen therapy?
- A. Storage of oxygen tanks will require adequate space in the home.
- B. Travel opportunities will be limited because of the use of oxygen.
- C. Oxygen flow should be increased if the patient has dyspnea.
- D. Oxygen use can improve the patient's quality of life and survival.
Correct Answer: D
Rationale: Research shows that oxygen use can improve quality of life and survival in patients with COPD. Storage considerations, travel limitations, and oxygen flow adjustments require specific guidance, but the primary benefit to emphasize is the improvement in quality of life and survival.
The nurse is admitting a patient with chronic obstructive pulmonary disease (COPD) to the hospital. Which of the following positions should the nurse place the patient in to improve gas exchange?
- A. Resting in bed with the head elevated to 45-60 degrees.
- B. Sitting up at the bedside in a chair and leaning slightly forward.
- C. Resting in bed in a high Fowler's position with the knees flexed.
- D. In the Trendelenburg position with several pillows behind the head.
Correct Answer: B
Rationale: Patients with COPD improve the mechanics of breathing by sitting up in the 'tripod' position. Resting in bed with the head elevated would be an alternative position if the patient was confined to bed, but sitting in a chair allows better ventilation. The Trendelenburg position or sitting upright in bed with the knees flexed would decrease the patient's ability to ventilate well.
The nurse is assessing a patient in the asthma clinic who has recorded daily peak flows that are 85% of the baseline. Which of the following actions should the nurse plan to take?
- A. Teach the patient about the use of oral corticosteroids.
- B. Administer a bronchodilator and recheck the peak flow.
- C. Instruct the patient to continue to use current medications.
- D. Evaluate whether the peak flow meter is being used correctly.
Correct Answer: C
Rationale: The patient's peak flow readings indicate good asthma control (values over 80%) and no changes are needed. The other actions would be used for patients in the yellow or red zones for peak flow.
The nurse is conducting an admission history for a patient with possible asthma who has new-onset wheezing and shortness of breath. Which of the following information indicates a need for a change in therapy?
- A. The patient has a history of pneumonia 2 years ago.
- B. The patient has chronic inflammatory bowel disease.
- C. The patient takes propranolol for hypertension.
- D. The patient uses acetaminophen for headaches.
Correct Answer: C
Rationale: β-Blockers such as propranolol can cause bronchospasm in some patients. The other information will be documented in the health history but does not indicate a need for a change in therapy.
The nurse is interviewing a patient with a new diagnosis of chronic obstructive pulmonary disease (COPD). Which of the following information will help most in confirming a diagnosis of chronic bronchitis?
- A. The patient tells the nurse about a family history of bronchitis.
- B. The patient's history indicates a 40 pack-year cigarette history.
- C. The patient denies having any respiratory problems until the last 6 months.
- D. The patient complains about a productive cough every winter for 3 months.
Correct Answer: D
Rationale: A diagnosis of chronic bronchitis is based on a history of having a productive cough for 3 months for at least 2 consecutive years. There is no familial tendency for chronic bronchitis. Although smoking is the major risk factor for chronic bronchitis, a smoking history does not confirm the diagnosis.
