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 reports a headache and vertigo after turning on his furnace for the first time this season. The nurse should suspect which of the following conditions?

• A. Carbon monoxide poisoning
• B. Heat stroke
• C. Hypersensitivity reaction
• D. Oxygen toxicity

Correct answer: A

Rationale: When a client reports headache and vertigo after turning on the furnace for the first time, it suggests carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be released by malfunctioning heating systems. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. It is crucial for the nurse to suspect this condition promptly to ensure the client's safety and well-being.

3. 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.

4. A client in the late stage of inhalation anthrax requires a plan of care. What is appropriate to include in the plan of care?

• A. Provide respiratory support.
• B. Place the client in droplet isolation.
• C. Administer antihypertensive medications.
• D. Monitor ascites.

Correct answer: A

Rationale: In the late stage of inhalation anthrax, respiratory support is crucial due to the potential for respiratory failure. Providing oxygen therapy and maintaining airway patency are essential components of care to improve oxygenation and support respiratory function. Placing the client in droplet isolation is not necessary as inhalation anthrax is not transmitted from person to person through respiratory droplets. Administering antihypertensive medications is not indicated in the treatment of inhalation anthrax. Monitoring for ascites is not a priority in the late stage of inhalation anthrax.

5. A client in the intensive care unit is receiving teaching before removal of an endotracheal tube. Which of the following instructions should the nurse include in the teaching?

• A. Rest in a side-lying position after the tube is removed.
• B. Use the incentive spirometer every 4 hours after the tube is removed.
• C. Avoid speaking for extended periods.
• D. Vital signs will be monitored by a nurse every 15 minutes in the first hour after the tube is removed.

Correct answer: C

Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.
