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. A client is scheduled for a colonoscopy and receiving education from a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I can have clear liquids up to 2 hours before the procedure.
• B. I need to take a laxative the night before the procedure.
• C. I will be sedated during the procedure.
• D. I should avoid eating solid foods for 24 hours before the procedure.

Correct answer: D

Rationale: The correct answer is D because clients are typically instructed to avoid solid foods for 12-24 hours before a colonoscopy, not a full 24 hours. This statement indicates a need for further teaching to ensure the client follows the correct dietary instructions for the procedure.

4. A client has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?

• A. Continuous bubbling in the water-seal chamber
• B. Occasional bubbling in the water-seal chamber
• C. Constant bubbling in the suction-control chamber
• D. Fluctuations in the fluid level in the water-seal chamber

Correct answer: A

Rationale: Continuous bubbling in the water-seal chamber indicates air is leaking into the pleural space, which is a complication. The water-seal chamber should have intermittent bubbling during normal functioning. Occasional bubbling in the water-seal chamber is normal and shows the system is working as intended. Constant bubbling in the suction-control chamber suggests an issue with the suction control. Fluctuations in the fluid level in the water-seal chamber are an expected finding.

5. A healthcare professional is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the healthcare professional anticipate administering?

• A. Furosemide
• B. Dexamethasone
• C. Heparin
• D. Atropine

Correct answer: C

Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.
