Question 1 of 5
A nurse is caring for a client who has respiratory acidosis. Which of the following pH levels should the nurse expect?
Correct Answer: C
Rationale: A pH of 7.31 indicates acidemia, consistent with respiratory acidosis due to carbon dioxide retention.
Question 2 of 5
A nurse is assessing a client who has respiratory alkalosis. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: Hyperventilation is a hallmark of respiratory alkalosis, causing excessive carbon dioxide loss and increased blood pH.
Question 3 of 5
A nurse is reviewing the arterial blood gas (ABG) results of a client. The client's ABGs are: PH: 7.6, PaCO2: 40 mm Hg, HCO3,: 32 mEq/L. Which of the following acid base conditions should the nurse identify the client is experiencing?
Correct Answer: D
Rationale: A high pH (7.6) and high bicarbonate (32 mEq/L) indicate metabolic alkalosis, with normal PaCO2 ruling out respiratory causes.
Question 4 of 5
A nurse is assisting in the plan of care for a client who has a suspected myocardial infarction. Which of the following medication should the nurse plan to administer first?
Correct Answer: B
Rationale: Aspirin is administered first for suspected myocardial infarction to inhibit platelet aggregation and reduce clot formation, minimizing heart damage.
