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.

After the nurse has finished teaching a patient about pursed lip breathing, which of the following patient actions indicate that more teaching is needed?
- A. The patient inhales slowly through the nose.
- B. The patient tenses the neck muscles while exhaling.
- C. The patient practises by blowing through a straw.
- D. The patient's ratio of inhalation to exhalation is 1:3.
Correct Answer: B
Rationale: The patient should relax the neck and shoulder muscles while doing pursed lip breathing. The other actions by the patient indicate a good understanding of pursed lip breathing.
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.
Which of the following actions should be included in the plan of care for a patient with cystic fibrosis (CF) who is admitted to the hospital with increased dyspnea?
- A. Schedule a sweat chloride test.
- B. Arrange for a hospice nurse visit.
- C. Place the patient on a low-sodium diet.
- D. Perform chest physiotherapy every 4 hours.
Correct Answer: D
Rationale: Routine scheduling of airway clearance techniques is an essential intervention for patients with CF. A sweat chloride test is used to diagnose CF, but it does not provide any information about the effectiveness of therapy. There is no indication that the patient is terminally ill. Patients with CF lose excessive sodium in their sweat and require high amounts of dietary sodium.
Which of the following diagnostic tests should the nurse plan to discuss with a patient who has progressively increasing dyspnea and is being evaluated for a possible diagnosis of chronic obstructive pulmonary disease (COPD)?
- A. Eosinophil count.
- B. Spirometry.
- C. Immunoglobin E (IgE) levels.
- D. Radioallergosorbent test (RAST).
Correct Answer: B
Rationale: The diagnosis of COPD is confirmed by spirometry regardless of whether the patient has chronic symptoms. The other tests would be used to test for an allergic component for asthma, but will not be used in the diagnosis of COPD.
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.
