A nurse is caring for a client who has been taking warfarin and has an international normalized ratio (INR) time of 5. Which of the following medications should the nurse anticipate the provider to prescribe?

(A) Respiratory acidosis: Respiratory acidosis is characterized by a low pH (<7.35) and a high PaCO2 (>45 mm Hg). In this case, the client’s pH is high and PaCO2 is normal, which rules out respiratory acidosis.

(B) Respiratory alkalosis: Respiratory alkalosis is characterized by a high pH (>7.45) and a low PaCO2 (<35 mm Hg). Although the client’s pH is high, the PaCO2 is normal, which rules out respiratory alkalosis.

(C) Metabolic acidosis: Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (<22 mEq/L). The client’s pH and bicarbonate levels are both high, which rules out metabolic acidosis.

(D) Metabolic alkalosis: Metabolic alkalosis is characterized by a high pH (>7.45) and a high bicarbonate level (>26 mEq/L). The client’s pH is 7.6 and bicarbonate level is 32 mEq/L, both of which are higher than normal. This indicates metabolic alkalosis. Therefore, the nurse should identify that the client is experiencing metabolic alkalosis.

A) Describe the surgery and what the client will experience postoperatively:
While it is essential to provide information about the surgery and the postoperative experience, the primary focus of preoperative teaching is to ensure that the client understands the information provided. This option does not specifically address the client's level of understanding, which is crucial for effective teaching.

B) Reinforce information at the client's level of understanding:
This is the correct choice. When contributing to the preoperative teaching plan, the nurse should ensure that information is provided in a way that the client can comprehend. Reinforcing information at the client's level of understanding enhances communication and ensures that the client is well-informed about the procedure and what to expect.

C) Reassure the client that the surgery rarely has any negative outcomes:
While it is important to provide reassurance and support to the client, it is not appropriate to make promises or provide guarantees about the outcome of the surgery. Surgery, by its nature, carries risks, and it is essential to provide the client with accurate information while maintaining a supportive and empathetic approach.

D) Notify the client's family of the plan of care:
While it is important to involve the client's family in the plan of care, the primary focus of preoperative teaching is on the client. Involving the family in the plan of care is important, but it is not the most immediate action in the context of preoperative teaching.
