A nurse reviewing the medical record of a patient who has metabolic acidosis should realize that which of the following findings contributes to the development of metabolic acidosis?

Diarrhea

Salicylate intoxication

Vomiting

Hyperventilation

Answer and Explanation

The Correct Answer is A

Choice A reason: Diarrhea can lead to metabolic acidosis due to the loss of bicarbonate, which is a base, leading to a relative increase in acidity.

Choice B reason: Salicylate intoxication can initially cause respiratory alkalosis due to hyperventilation, but may later lead to metabolic acidosis as the body compensates.

Choice C reason: Vomiting typically leads to a loss of gastric acid, which would cause metabolic alkalosis, not acidosis.

Choice D reason: Hyperventilation is more commonly associated with respiratory alkalosis due to the excessive loss of CO2, which is an acid, not metabolic acidosis.

Correct Answer is A

Explanation

Choice A reason: Elevating the patient in a high Fowler's position can help improve lung expansion and oxygenation, and using an incentive spirometer along with coughing can help prevent atelectasis and pneumonia, which are common postoperative complications.

Choice B reason: Increasing oxygen to 70% without a specific indication could lead to oxygen toxicity, especially without assessing the patient's current oxygenation status.

Choice C reason: Switching to a rebreather mask is not indicated based on the given ABG results and could lead to CO2 retention.

Choice D reason: Positioning the patient prone and performing postural drainage are not typically first-line interventions for a patient one day post-thoracotomy and could be contraindicated due to the recent surgery.

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.
