Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

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

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. While dining at a restaurant, a person begins to choke. Which of the following actions should the nurse take?

• A. Instruct the person to call 911.
• B. Ask the person if he/she can speak.
• C. Use the jaw-thrust maneuver.
• D. Perform abdominal thrusts.

Correct answer: B

Rationale: When encountering a choking individual, the nurse should first assess the person's ability to speak. If the person can speak, it indicates that their airway is partially obstructed, allowing some air to pass. In this case, encouraging the person to continue coughing and monitoring them closely may be appropriate. If the person cannot speak, it may suggest a complete airway obstruction and immediate intervention is required. Instructing the person to call 911 (Choice A) may be necessary if the situation worsens. Using the jaw-thrust maneuver (Choice C) is not appropriate for a choking victim. Performing abdominal thrusts (Choice D) is typically recommended for conscious choking victims, not chest compressions.

3. A healthcare provider is assessing a client immediately after the removal of the endotracheal tube. Which of the following findings should the provider report to the healthcare provider?

• A. Stridor
• B. Copious oral secretions
• C. Hoarseness
• D. Sore throat

Correct answer: A

Rationale: Stridor is a high-pitched, harsh respiratory sound that can indicate airway obstruction. It is a serious finding that requires immediate attention as it may lead to respiratory compromise. Copious oral secretions, hoarseness, and sore throat are common but expected findings after endotracheal tube removal and do not typically require urgent intervention.

4. A client with deep vein thrombosis (DVT) is receiving heparin therapy. What is the priority assessment for the nurse?

• A. Monitoring blood pressure
• B. Checking the activated partial thromboplastin time (aPTT)
• C. Assessing for signs of bleeding
• D. Measuring calf circumference

Correct answer: C

Rationale: Assessing for signs of bleeding is the priority when caring for a client with deep vein thrombosis (DVT) receiving heparin therapy. Heparin therapy increases the risk of bleeding complications, so monitoring for signs of bleeding is crucial to ensure patient safety and timely intervention if needed.

5. The client with a chest tube after a coronary artery bypass graft has significantly slowed drainage. What action is most important for the nurse to take?

• A. Increase the setting on the suction.
• B. Notify the provider immediately.
• C. Re-position the chest tube.
• D. Take the tubing apart to assess for clots.

Correct answer: B

Rationale: If the drainage from the chest tube decreases significantly, it may indicate a blockage by a clot, potentially leading to cardiac tamponade. The nurse's priority action should be to notify the healthcare provider immediately for further evaluation and intervention. Increasing suction, re-positioning the chest tube, or disassembling the tubing independently are not appropriate actions without healthcare provider guidance in this situation.
