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 healthcare provider is preparing to admit a client to the PACU who received a competitive neuromuscular blocking agent. Which of the following items should the provider place at the client's bedside?

• A. Bag valve mask device
• B. Defibrillator machine
• C. Chest tube equipment
• D. Central venous catheter tray

Correct answer: A

Rationale: When a client receives a competitive neuromuscular blocking agent, it can lead to respiratory muscle paralysis. Placing a bag valve mask device at the client's bedside is crucial for providing immediate respiratory support in case of respiratory depression or failure. This device allows manual ventilation by squeezing the bag to deliver breaths to the client. The other options, such as a defibrillator machine, chest tube equipment, and central venous catheter tray, are not directly related to managing respiratory complications associated with neuromuscular blockade.

3. 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.

4. When prioritizing client care after receiving change-of-shift report, which of the following clients should the nurse plan to see first?

• A. A client who is scheduled for an abdominal x-ray and is awaiting transport
• B. A client who has a prescription for discharge
• C. A client who received oral pain medication 30 minutes ago
• D. A client who told an assistive personnel he is short of breath

Correct answer: D

Rationale: When a client expresses being short of breath, it may indicate a serious condition requiring immediate attention to ensure adequate oxygenation. This client should be seen first to assess the severity of the situation and initiate appropriate interventions. The other options, such as awaiting transport for an x-ray, having a prescription for discharge, or receiving oral pain medication 30 minutes ago, do not present immediate life-threatening concerns compared to a client experiencing shortness of breath.

5. A client with emphysema is being assessed by a nurse. Which clinical manifestation should the nurse expect?

• A. Decreased chest expansion
• B. Cyanosis
• C. Pursed-lip breathing
• D. Bradypnea

Correct answer: C

Rationale: Pursed-lip breathing is a common manifestation in clients with emphysema. It helps to increase the duration of exhalation and reduce air trapping, aiding in the management of the condition. Decreased chest expansion and bradypnea are not typically associated with emphysema. While cyanosis can occur in severe cases, pursed-lip breathing is a more specific and commonly observed sign of emphysema.
