A patient's ABG results came back with the following values: pH 7.25, CO2 40, HCO3 22. How would you, as the nurse, interpret these results?

Metabolic acidosis

Respiratory acidosis

Metabolic alkalosis

Respiratory alkalosis

Answer and Explanation

The Correct Answer is A

Choice A reason: Metabolic acidosis is characterized by a low pH and a normal or low HCO3. In this case, the pH is 7.25, which is below the normal range of 7.35-7.45, and the HCO3 is 22, which is at the lower end of the normal range of 22-26 mEq/L, indicating metabolic acidosis.

Choice B reason: Respiratory acidosis is characterized by a high CO2 level. However, in this scenario, the CO2 is 40, which is within the normal range of 35-45 mmHg, ruling out respiratory acidosis.

Choice C reason: Metabolic alkalosis would present with a high pH and a high HCO3 level. Since the pH is low, metabolic alkalosis is not the correct answer.

Choice D reason: Respiratory alkalosis is characterized by a low CO2 level and a high pH. Given that the CO2 is normal and the pH is low, respiratory alkalosis is not the condition indicated by these ABG results.

Correct Answer is D

Explanation

Choice A reason: While opioids can lower blood pressure, it is not as common as respiratory depression.

Choice B reason: Causing drowsiness is a common side eﬀect of opioids, but it is less critical than respiratory eﬀects.

Choice C reason: Opioids do not typically induce a cough; they may actually suppress coughing.

Choice D reason: Opioids can slow the respiratory rate, which is a critical side eﬀect that nurses must monitor for and educate patients about.

A. Increased length of postoperative care in the health care facility B. Reduced postoperative respiratory function C. Increase in postoperative pain D. Induced postoperative anxiety

Correct Answer is B

Explanation

Choice A reason: Increased length of stay is not a direct outcome of preoperative teaching and depends on many factors.

Choice B reason: Reduced postoperative respiratory function can be a concern, and preoperative teaching aims to mitigate this risk by educating on breathing exercises and mobilization.

Choice C reason: Preoperative teaching should help manage expectations and pain control strategies, not increase postoperative pain.

Choice D reason: Preoperative teaching should aim to reduce anxiety by providing information and reassurance, not induce it.
