Nursing Elites

1. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.

2. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

3. When giving a report about a client who had a gastrectomy from the intensive care unit to the post-surgical unit nurse, what is the most effective way to assure essential information is reported?

• A. Give the report face-to-face with both nurses in a quiet room.
• B. Audiotape the report for future reference and documentation.
• C. Use a printed checklist with information individualized for the client.
• D. Document essential transfer information in the client's electronic health record.

Correct answer: C

Rationale: Using a printed checklist with individualized information is the most effective way to ensure that all key details about the client who had a gastrectomy are covered during the report. This method helps in structuring the information systematically, reducing the risk of missing important details. Face-to-face communication in a quiet room (Choice A) is important for effective communication but may not guarantee the coverage of all essential information. Audiotaping the report (Choice B) may not be practical for immediate reference or interaction. Documenting in the electronic health record (Choice D) is essential but may not facilitate a comprehensive real-time exchange of information between the nurses.

4. After three days of persistent epigastric pain, a female client presents to the clinic. She has been taking oral antacids without relief. Her vital signs are heart rate 122 beats/minute, respirations 16 breaths/minute, oxygen saturation 96%, and blood pressure 116/70. The nurse obtains a 12-lead electrocardiogram (ECG). Which assessment finding is most critical?

• A. Irregular pulse rhythm
• B. Bile-colored emesis
• C. ST elevation in three leads
• D. Complaint of radiating jaw pain

Correct answer: C

Rationale: ST elevation in three leads is a critical finding that suggests myocardial infarction, requiring immediate attention. This finding indicates ischemia or injury to the heart muscle. Choices A, B, and D are not as critical in this scenario. Irregular pulse rhythm may be concerning but does not indicate an immediate life-threatening condition like myocardial infarction. Bile-colored emesis and complaint of radiating jaw pain are relevant but not as indicative of a myocardial infarction as ST elevation in three leads.

5. A client who has just undergone a skin biopsy is listening to discharge instructions from the nurse. The nurse determines that the client has misunderstood the directions if the client indicates that as part of aftercare he plans to:

• A. Use the antibiotic ointment as prescribed
• B. Return in 7 days to have the sutures removed
• C. Apply cool compresses to the site twice a day for 20 minutes
• D. Call the physician if excessive drainage from the wound occurs

Correct answer: C

Rationale: The correct answer is C. Applying cool compresses to the site twice a day for 20 minutes is not a recommended aftercare practice for a skin biopsy. After a skin biopsy, it is important to keep the dressing dry and in place for a minimum of 8 hours. Choice A is correct as using the antibiotic ointment as prescribed is a common post-biopsy instruction to prevent infection. Choice B is also correct as returning in 7 days to have the sutures removed is part of the typical follow-up care after a skin biopsy. Choice D is correct as it is important to call the physician if excessive drainage from the wound occurs to prevent complications.
