The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?
- A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
- B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
- C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
- D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%
Correct Answer: D
Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

Using the illustrated technique, the healthcare provider is assessing for which finding in a patient with chronic obstructive pulmonary disease (COPD)?
- A. Hyperresonance
- B. Tripod positioning
- C. Accessory muscle use
- D. Reduced chest expansion
Correct Answer: D
Rationale: The technique for palpation for chest expansion is shown in the illustrated technique. Reduced chest expansion would be noted on palpation of a patient's chest with COPD. Hyperresonance would be assessed through percussion, not palpation. Accessory muscle use and tripod positioning would be assessed by inspection, not palpation.
The nurse monitors a patient after chest tube placement for a hemopneumothorax. The nurse is most concerned if which assessment finding is observed?
- A. A large air leak in the water-seal chamber
- B. 400 mL of blood in the collection chamber
- C. Complaint of pain with each deep inspiration
- D. Subcutaneous emphysema at the insertion site
Correct Answer: B
Rationale: The nurse should be most concerned if 400 mL of blood is observed in the collection chamber as it may indicate the patient is at risk of developing hypovolemic shock. A large air leak in the water-seal chamber is expected initially after chest tube placement for a pneumothorax. While pain with deep inspiration should be treated, it is not as urgent as the risk of continued hemorrhage. Subcutaneous emphysema is not uncommon in a patient with pneumothorax and is usually harmless. However, a large amount of blood in the collection chamber is a more critical finding that requires immediate attention to prevent potential complications.
The patient who has two fractured ribs from an automobile accident is receiving discharge teaching. Which statement by the patient indicates effective teaching?
- A. I am going to buy a rib binder to wear during the day.
- B. I can take shallow breaths to prevent my chest from hurting.
- C. I should plan on taking the pain pills only at bedtime so I can sleep.
- D. I will use the incentive spirometer every hour or two during the day.
Correct Answer: D
Rationale: The correct answer is, 'I will use the incentive spirometer every hour or two during the day.' After sustaining rib fractures, it is crucial to prevent complications like atelectasis and pneumonia by practicing deep breathing and coughing. Using the incentive spirometer helps in maintaining lung expansion and preventing respiratory issues. Buying a rib binder could restrict chest expansion and hinder deep breathing efforts, increasing the risk of atelectasis. Taking shallow breaths may not effectively expand the lungs, leading to potential respiratory complications. Relying solely on pain medication at bedtime may not adequately address the need for lung expansion and prevention of respiratory complications during the day.
An older patient is receiving standard multidrug therapy for tuberculosis (TB). The nurse should notify the health care provider if the patient exhibits which finding?
- A. Yellow-tinged skin
- B. Orange-colored sputum
- C. Thickening of the fingernails
- D. Difficulty hearing high-pitched voices
Correct Answer: A
Rationale: The correct answer is 'Yellow-tinged skin.' Yellow-tinged skin is indicative of noninfectious hepatitis, a toxic effect of isoniazid (INH), rifampin, and pyrazinamide. If a patient on TB therapy develops hepatotoxicity, alternative medications will be necessary. Thickening of fingernails and difficulty hearing high-pitched voices are not typical side effects of the medications used in standard TB therapy. Presbycusis, age-related hearing loss, is common in older adults and not a cause for immediate concern. Orange-colored sputum is an expected side effect of rifampin and does not warrant immediate notification to the healthcare provider.
The patient is being taught about pulmonary function testing (PFT). Which statement made by the patient indicates effective teaching?
- A. I will use my inhaler right before the test.
- B. I won't eat or drink anything 8 hours before the test.
- C. I should inhale deeply and blow out as hard as I can during the test.
- D. My blood pressure and pulse will be checked every 15 minutes after the test.
Correct Answer: C
Rationale: The correct answer is 'I should inhale deeply and blow out as hard as I can during the test.' This statement indicates effective teaching because for PFT, the patient needs to inhale deeply and exhale forcefully. This maneuver helps in assessing lung function accurately. Choices A, B, and D are incorrect. Using an inhaler right before the test may alter the test results, which is not recommended. Fasting for 8 hours is not necessary for a PFT, and checking blood pressure and pulse every 15 minutes after the test is not part of the PFT procedure.
