After the nurse has received change-of-shift report about the following four patients, which patient should be assessed first?
- A. A 7-year-old patient with tuberculosis (TB) who has four antitubercular medications due in 15 minutes
- B. A 23-year-old patient with cystic fibrosis who has pulmonary function testing scheduled
- C. A 46-year-old patient who has a deep vein thrombosis and is complaining of sudden onset shortness of breath
- D. A 35-year-old patient who was admitted the previous day with pneumonia and has a temperature of 37.9 C (100.2 F)
Correct Answer: C
Rationale: Sudden onset shortness of breath in a patient with a deep vein thrombosis suggests a pulmonary embolism and requires immediate assessment and actions such as oxygen administration. The other patients also should be assessed as soon as possible, but there is no indication that they may need immediate action to prevent clinical deterioration.

The nurse is performing tuberculosis (TB) screening in a clinic that has many patients who have immigrated to Canada. Before doing a TB skin test on a patient, which of the following questions is most important for the nurse to ask?
- A. Is there any family history of TB?
- B. Have you received the bacille Calmette-Guérin (BCG) vaccine for TB?
- C. How long have you lived in the Canada?
- D. Do you take any over-the-counter (OTC) medications?
Correct Answer: B
Rationale: Patients who have received the BCG vaccine will have a positive Mantoux test. Another method for screening (such as a chest x-ray) will need to be used in determining whether the patient has a TB infection. The other information also may be valuable but is not as pertinent to the decision about doing TB skin testing.
The nurse is assessing a patient who has just arrived after an automobile accident and the nurse notes that the breath sounds are absent on the right side. Which of the following actions should the nurse anticipate?
- A. Emergency pericardiocentesis
- B. Stabilization of the chest wall with tape
- C. Administration of an inhaled bronchodilator
- D. Insertion of a chest tube with a chest drainage system
Correct Answer: D
Rationale: The patient's history and absent breath sounds suggest a right-sided pneumothorax or hemothorax, which will require treatment with a chest tube and drainage. The other therapies would be appropriate for an acute asthma attack, flail chest, or cardiac tamponade, but the patient's clinical manifestations are not consistent with these problems.
Which of the following actions by the occupational health nurse at a manufacturing plant where there is potential exposure to inhaled dust is most helpful in reducing incidence of lung disease?
- A. Teach about symptoms of lung disease.
- B. Treat workers who inhale dust particles
- C. Monitor workers for shortness of breath
- D. Require the use of protective equipment
Correct Answer: D
Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks. The other actions will help in recognition or early treatment of lung disease, but will not be effective in prevention of lung damage.
The nurse is providing teaching to a patient with pneumonia. Which of the following patient statements indicate a good understanding of the discharge instructions given by the nurse?
- A. I will call the doctor if I still feel tired after a week.
- B. I will need to use home oxygen therapy for 3 months.
- C. I will continue to do the deep-breathing and coughing exercises at home.
- D. I will schedule two appointments for the pneumonia and influenza vaccines.
Correct Answer: C
Rationale: Patients should continue to cough and deep breathe after discharge for up to 6-8 weeks. Fatigue for several weeks is expected. Home oxygen therapy is not needed with successful treatment of pneumonia. The pneumonia and influenza vaccines can be given at the same time.
The nurse is caring for a patient with primary pulmonary hypertension (PPH) who is receiving nifedipine. Which of the following findings indicate that the treatment is effective?
- A. BP is less than 140/90 mm Hg
- B. Patient reports decreased exertional dyspnea.
- C. Heart rate is between 60 and 100 beats/minute.
- D. Patient's chest x-ray indicates clear lung fields.
Correct Answer: B
Rationale: Since a major symptom of PPH is exertional dyspnea, an improvement in this symptom would indicate that the medication was effective. Nifedipine will affect BP and heart rate, but these parameters would not be used to monitor effectiveness of therapy for a patient with PPH. The chest x-ray will show clear lung fields even if the therapy is not effective.
