Nokea
The nurse is caring for a patient who is hospitalized with cystic fibrosis (CF) and is coughing up large quantities of thick green mucus. Which of the following treatments should the nurse include in the teaching plan?
- A. Antibiotic resistance.
- B. Inhaled bronchodilators.
- C. Oral corticosteroid therapy.
- D. Aerosolized amoxicillin.
Correct Answer: D
Rationale: The colour of the mucus and the patient's history of CF suggests Pseudomonas infection; an antibiotic is required. Oral corticosteroids and inhaled bronchodilators will not be effective in treating the respiratory infection; the effectiveness of bronchodilators has not been established for CF. Pseudomonas infections are usually responsive (not resistant) to TOBI.

Which of the following topics should the nurse include in medication teaching for a patient with newly diagnosed persistent asthma?
- A. Use of long-acting β-adrenergic medications.
- B. Adverse effects of sustained-release theophylline.
- C. Self-administration of inhaled corticosteroids.
- D. Complications associated with oxygen therapy.
Correct Answer: C
Rationale: Inhaled corticosteroids are more effective in improving asthma than any other drug and are indicated for all patients with persistent asthma. The other therapies would not typically be first-line treatments for newly diagnosed asthma.
The nurse is caring for a patient with cystic fibrosis (CF) who has blood glucose levels that are consistently 11-14 mmol/L. Which of the following nursing actions should the nurse plan to implement?
- A. Discuss the role of diet in blood glucose control.
- B. Educate the patient about administration of insulin.
- C. Give oral hypoglycemic medications before meals.
- D. Evaluate the patient's home use of pancreatic enzymes.
Correct Answer: B
Rationale: The glucose levels indicate that the patient has developed CF-related diabetes; insulin therapy will be required. Since the etiology of diabetes in CF is inadequate insulin production, oral hypoglycemic agents are not effective. Patients with CF need a high-calorie diet. Inappropriate use of pancreatic enzymes would not be a cause of hyperglycemia in a patient with CF.
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 preparing a patient with possible asthma for pulmonary function testing. Which of the following instructions should the nurse include in the teaching plan?
- A. Avoid eating or drinking for several hours before the testing.
- B. Use rescue medications immediately before the tests are done.
- C. Take oral corticosteroids at least 2 hours before the examination.
- D. Withhold bronchodilators for 6-12 hours before the examination.
Correct Answer: D
Rationale: Bronchodilators are held before pulmonary function testing so that a baseline assessment of airway function can be determined. Testing is repeated after bronchodilator use to determine whether the decrease in lung function is reversible. There is no need for the patient to be NPO. Oral corticosteroids also should be held before the examination and corticosteroids given 2 hours before the examination would be at a high level. Rescue medications (which are bronchodilators) would not be given until after the baseline pulmonary function was assessed.
The nurse is teaching a patient about continuous home oxygen use and cautions the patient to take extra care to not run out of oxygen. Which of the following seasons should the nurse instruct the patient has the highest rate of oxygen evaporation?
- A. Spring.
- B. Summer.
- C. Fall.
- D. Winter.
Correct Answer: B
Rationale: During the summer, with liquid oxygen, evaporation is accelerated and may decrease reservoir duration to less than 1 week.
