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 with chronic obstructive pulmonary disease is being taught by a nurse about ways to facilitate eating. Which of the following statements indicates a need for further teaching?

• A. I will rest for at least 30 minutes before eating.
• B. I will take my bronchodilators after meals.
• C. I will eat five or six small meals each day.
• D. I will choose foods that are not gas-forming.

Correct answer: B

Rationale: Option B, 'I will take my bronchodilators after meals,' indicates a need for further teaching. Bronchodilators should be taken before meals to help open the airways and make breathing easier before eating. This statement suggests a misunderstanding of the timing for optimal bronchodilator effectiveness. Options A, C, and D are all appropriate strategies for facilitating eating for a client with chronic obstructive pulmonary disease.

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 who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?

• A. 300 mL
• B. 480 mL
• C. 800 mL
• D. 950 mL

Correct answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.

5. During an assessment of the respiratory pattern of an older adult client receiving end-of-life care, which of the following assessment findings should the nurse identify as Cheyne-Stokes respirations?

• A. Breathing ranging from very deep to very shallow with periods of apnea
• B. Shallow to normal breaths alternating with periods of apnea
• C. Rapid respirations that are unusually deep and regular
• D. An inability to breathe without dyspnea unless sitting upright

Correct answer: A

Rationale: Cheyne-Stokes respirations are characterized by a pattern of breathing that ranges from very deep to very shallow with periods of apnea (temporary cessation of breathing). This pattern is often seen in clients near the end of life or with certain medical conditions affecting the respiratory control center in the brain. The alternating deep and shallow breaths can be distressing for both the client and caregivers. It is crucial for the nurse to recognize this pattern to provide appropriate care and support to the client and their family during this challenging time.
