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 has a pulmonary embolism & is started on oxygen. The student nurse asks why the client's oxygen saturation has not significantly improved. What response by the nurse is best?

• A. Breathing so rapidly interferes with oxygenation.
• B. Maybe the client has respiratory distress syndrome.
• C. The blood clot interferes with perfusion in the lungs.
• D. The client needs immediate intubation & mechanical ventilation.

Correct answer: C

Rationale: A large blood clot in the lungs will significantly impair gas exchange & oxygenation. Unless the clot is dissolved, this process will continue unabated.

3. 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.

4. A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

• A. Pigeon
• B. Funnel
• C. Kyphotic
• D. Barrel

Correct answer: D

Rationale:

5. A client with end-stage heart failure who is awaiting a transplant appears depressed and states, 'I know a transplant is my last chance, but I don't want to become a vegetable.' How should the nurse respond?

• A. Would you like information about advance directives?
• B. I will arrange for a psychiatrist to speak with you.
• C. Do you want to come off the transplant list?
• D. Would you like to speak with a priest or chaplain?

Correct answer: A

Rationale: The client is expressing a fear of negative outcomes related to the transplant. By offering information about advance directives, the nurse allows the client to discuss concerns and preferences for end-of-life care. This response shows empathy, acknowledges the client's autonomy, and addresses the client's fears while providing support and information.
