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. A client is caring for a postoperative client on the surgical unit. The client's blood pressure was 142/76 mm Hg 30 minutes ago and is now 88/50 mm Hg. What action by the nurse is best?

• A. Call the Rapid Response Team.
• B. Document and continue to monitor.
• C. Notify the primary care provider.
• D. Repeat blood pressure measurement in 15 minutes.

Correct answer: A

Rationale: In this scenario, the significant drop in blood pressure indicates a potential emergency situation. The correct action is to call the Rapid Response Team (RRT) to ensure prompt intervention and prevent further deterioration that could lead to respiratory or cardiac arrest. It is crucial to act swiftly in response to such a critical change in vital signs to provide the client with the necessary care and support.

3. A client has burns to his face, ears, and eyelids. What is the priority finding for the nurse to report to the provider?

• A. Urinary output of 25 mL/hr
• B. Difficulty swallowing
• C. Heart rate of 122/min
• D. Pain level of 6 on a scale of 0 to 10

Correct answer: B

Rationale: When a client has burns involving the face, ears, and eyelids, the priority finding to report to the provider is difficulty swallowing. This symptom could indicate potential airway compromise or swelling in the throat, which can lead to serious complications. Monitoring and addressing this issue promptly is crucial to ensure the client's airway remains patent and secure.

4. A client in the emergency department is being cared for by a nurse and has cardiogenic pulmonary edema. The client's assessment findings include anxiousness, dyspnea at rest, crackles, blood pressure 110/79 mm Hg, and apical heart rate 112/min. What is the nurse's priority intervention?

• A. Provide the client with supplemental oxygen at 5 L/min via facemask.
• B. Place the client in high-Fowler's position with their legs in a dependent position
• C. Give the client sublingual nitroglycerin
• D. Administer morphine sulfate IV

Correct answer: A

Rationale: In cardiogenic pulmonary edema, the priority intervention is to improve oxygenation and reduce the workload on the heart. Providing supplemental oxygen at 5 L/min via facemask helps increase oxygen levels and alleviate respiratory distress. This intervention can help improve oxygen saturation, alleviate dyspnea, and support the client's respiratory function. Placing the client in a high-Fowler's position with legs dependent can also help with respiratory effort, but ensuring adequate oxygenation takes precedence. Sublingual nitroglycerin and IV morphine sulfate are commonly used interventions for cardiac-related conditions, but in this case, addressing oxygenation is the priority to prevent further deterioration.

5. A client is receiving discharge teaching after a total hip replacement. Which statement by the client indicates a need for further teaching?

• A. I will avoid crossing my legs when sitting.
• B. I can sleep on my side as long as I use a pillow between my legs.
• C. I will avoid bending at the waist to pick things up.
• D. I can bend down to tie my shoes after 2 weeks.

Correct answer: D

Rationale: After a total hip replacement, clients should avoid bending at the waist past 90 degrees for at least 6 weeks to prevent dislocation of the hip prosthesis. Bending down to tie shoes involves significant hip flexion and should be avoided during the initial postoperative period to ensure proper healing and reduce the risk of complications.
