Nursing Elites

1. A nurse is providing care to a 17-year-old client in the post-operative care unit (PACU) after an emergency appendectomy. Which finding is an early indication that the client is experiencing poor oxygenation?

• A. Abnormal breath sounds
• B. Cyanosis of the lips
• C. Increasing pulse rate
• D. Pulse oximeter reading of 92%

Correct answer: C

Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.

2. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

3. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

4. A client with a tracheostomy collar has a decrease in heart rate and oxygen saturation during tracheal suctioning. Which of the following actions should the nurse take?

• A. Elevate the head of the bed.
• B. Remove the inner cannula.
• C. Irrigate the stoma.
• D. Discontinue suctioning.

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to discontinue suctioning. Suctioning should be stopped immediately to prevent further decrease in heart rate and oxygen saturation. Elevating the head of the bed may help with oxygenation, but the priority is to stop the suctioning procedure. Removing the inner cannula or irrigating the stoma are not appropriate actions and could worsen the client's condition.

5. During a physical assessment, a nurse is assessing 4 adult clients. Which of the following physical assessment techniques should the nurse use?

• A. Ensure the bladder of the BP cuff surrounds 80% of their arm.
• B. Use the BP cuff on the forearm if the upper arm is not accessible.
• C. Apply the BP cuff loosely around the arm.
• D. Use a pediatric cuff for adults with small arms.

Correct answer: A

Rationale: The correct answer is to ensure the bladder of the BP cuff surrounds 80% of the arm. This technique is crucial for obtaining accurate blood pressure readings. Choice B is incorrect because using the BP cuff on the forearm may lead to inaccurate readings. Choice C is incorrect as applying the BP cuff loosely can also result in inaccurate measurements. Choice D is incorrect because using a pediatric cuff for adults with small arms would not provide accurate blood pressure readings.
