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.

When assessing a patient who has just arrived after an automobile accident, the emergency department nurse notes tachycardia and absent breath sounds over the right lung. For which intervention will the nurse prepare the patient?
- 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. Emergency pericardiocentesis is not indicated as the patient's symptoms are not suggestive of cardiac tamponade. Stabilization of the chest wall with tape would not address the underlying issue of a potential pneumothorax or hemothorax. Administration of an inhaled bronchodilator is not appropriate in this scenario as the patient is not exhibiting signs of asthma or bronchoconstriction. Therefore, the correct intervention for this patient is the insertion of a chest tube with a chest drainage system to address the potential pneumothorax or hemothorax.
The nurse plans health care for a community with a large number of recent immigrants from Vietnam. Which intervention is the most important for the nurse to implement?
- A. Hepatitis testing
- B. Tuberculosis screening
- C. Contraceptive teaching
- D. Colonoscopy information
Correct Answer: B
Rationale: Tuberculosis (TB) is prevalent in many parts of Asia, including Vietnam, and the incidence of TB is higher in immigrants from Vietnam compared to the general U.S. population. Conducting tuberculosis screening is crucial to identify and address any cases promptly, especially in a community with recent immigrants from Vietnam. While teaching about contraceptive use, providing colonoscopy information, and testing for hepatitis may be relevant for certain individuals in the community, they are not as universally important as tuberculosis screening due to the increased risk of TB among Vietnamese immigrants.
A 49-year-old patient with multiple sclerosis (MS) is to begin treatment with glatiramer acetate (Copaxone). Which information will the nurse include in patient teaching?
- A. Recommendation to drink at least 4 L of fluid daily
- B. Need to avoid driving or operating heavy machinery
- C. How to draw up and administer injections of the medication
- D. Use of contraceptive methods other than oral contraceptives
Correct Answer: C
Rationale: When initiating treatment with glatiramer acetate (Copaxone), patient education should focus on teaching the patient how to draw up and administer injections of the medication. Copaxone is administered via self-injection, hence understanding the correct technique is crucial for successful treatment. Recommendations regarding fluid intake or the need to avoid driving heavy machinery are not directly related to glatiramer acetate therapy. Additionally, while discussing contraceptive methods may be important, the use of oral contraceptives does not specifically contraindicate the use of glatiramer acetate.
The nurse provides discharge instructions to a patient who was hospitalized for pneumonia. Which statement, if made by the patient, indicates a good understanding of the instructions?
- A. I will call the doctor if I still feel tired after a week.
- B. I will continue to do the deep breathing and coughing exercises at home.
- C. I will continue to do the deep breathing and coughing exercises at home.
- D. I'll cancel my chest x-ray appointment if Im feeling better in a couple weeks
Correct Answer: C
Rationale: Patients should continue to cough and deep breathe after discharge. Fatigue is expected for several weeks. The Pneumovax and influenza vaccines can be given at the same time in different arms. Explain that a follow-up chest x-ray needs to be done in 6 to 8 weeks to evaluate resolution of pneumonia.
The nurse admits a patient who has a diagnosis of an acute asthma attack. Which statement indicates that the patient may need teaching regarding medication use?
- A. I have not had any acute asthma attacks during the last year.
- B. I became short of breath an hour before coming to the hospital.
- C. I've been taking Tylenol 650 mg every 6 hours for chest-wall pain.
- D. I've been using my albuterol inhaler more frequently over the last 4 days.
Correct Answer: D
Rationale: The correct answer is 'I've been using my albuterol inhaler more frequently over the last 4 days.' This statement indicates that the patient may need teaching regarding medication use because an increased need for a rapid-acting bronchodilator suggests an exacerbation of asthma. The patient should be educated on recognizing worsening symptoms and the appropriate actions to take. Choices A, B, and C do not directly relate to asthma exacerbation or the need for medication teaching, making them incorrect. Choice A reflects a lack of recent acute asthma attacks, while choice B describes shortness of breath unrelated to medication use. Choice C mentions Tylenol use for chest-wall pain, which is not indicative of asthma exacerbation or medication teaching needs.
