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 nurse is caring for a client who is postoperative following surgical repair of a mandibular fracture with fixed occlusion of the jaws in a closed position. Which of the following statements is the priority for the nurse to make?

• A. "We can teach you some relaxation techniques to minimize your pain."
• B. "Keep wire cutters with you at all times."
• C. "Use a water pick device to keep your teeth clean."
• D. "Consume a high-protein, liquid diet."

Correct answer: B

Rationale:

3. A client takes atorvastatin (Lipitor), with laboratory results showing a blood urea nitrogen (BUN) of 33 mg/dL and creatinine of 2.8 mg/dL. What action by the nurse is best?

• A. Ask if the client eats grapefruit.
• B. Assess the client for dehydration.
• C. Facilitate admission to the hospital.
• D. Obtain a random urinalysis.

Correct answer: A

Rationale: There is a drug-food interaction between statins and grapefruit that can lead to acute kidney failure. The client has elevated renal laboratory results, indicating kidney involvement. The nurse should ask if the client consumes grapefruit or grapefruit juice. While dehydration can elevate BUN, the increase in creatinine is more specific for kidney injury.

4. A healthcare professional is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the healthcare professional expect?

• A. Bradycardia
• B. Bradypnea
• C. Lethargy
• D. Intercostal retractions

Correct answer: D

Rationale: Postoperative atelectasis can lead to hypoxia, which causes respiratory distress. Intercostal retractions, where the muscles between the ribs pull inward during inspiration, are a common sign of respiratory distress in a client with atelectasis. Bradycardia (slow heart rate), Bradypnea (slow breathing rate), and lethargy are not typically associated with atelectasis and hypoxia.

5. When performing tracheostomy care, which intervention should the nurse implement?

• A. Use aseptic technique.
• B. Clean the inner cannula with mild soap and water.
• C. Secure new tracheostomy ties before removing old ones.
• D. Apply suction when inserting the catheter.

Correct answer: C

Rationale: When caring for a client with a tracheostomy, it is essential to ensure that the airway is maintained and secured at all times. Securing new tracheostomy ties before removing the old ones helps prevent accidental decannulation and ensures continuous airway patency. Aseptic technique is crucial to prevent infections but is not directly related to securing the tracheostomy ties. Cleaning the inner cannula with mild soap and water is important for maintaining hygiene but does not address the immediate need for securing the airway. Applying suction when inserting the catheter is not a standard practice during tracheostomy care.
