A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22 PaCO2 68 mm Hg Base excess -2 PaO2 78 mm Hg Oxygen saturation 80% Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?

Metabolic acidosis

Respiratory acidosis

Metabolic alkalosis

Respiratory alkalosis

Answer and Explanation

The Correct Answer is B

A. Metabolic acidosis

Metabolic acidosis is characterized by a low pH (< 7.35) and a decreased bicarbonate level (< 22 mEq/L). In this scenario, the pH is low (7.22), but the bicarbonate level is elevated (28 mEq/L), which does not support a diagnosis of metabolic acidosis.

B. Respiratory acidosis

Respiratory acidosis occurs when there is an accumulation of carbon dioxide (PaCO2 > 45 mm Hg), leading to a decrease in pH (< 7.35). In this case, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), consistent with respiratory acidosis.

C. Metabolic alkalosis

Metabolic alkalosis is characterized by a high pH (> 7.45) and an elevated bicarbonate level (> 26 mEq/L). In this scenario, the pH is low (7.22), and the bicarbonate level is also elevated (28 mEq/L), which does not support a diagnosis of metabolic alkalosis.

D. Respiratory alkalosis

Respiratory alkalosis occurs when there is a decrease in carbon dioxide (PaCO2 < 35 mm Hg), leading to an increase in pH (> 7.45). In this case, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), which is not consistent with respiratory alkalosis.

Correct Answer is A

Explanation

A. Provide humidified oxygen.

Humidified oxygen adds moisture to the air, which can help to thin secretions in the airway. Thinning the secretions makes them easier to clear, particularly for patients with copious and tenacious secretions, such as those following a tracheostomy.

B. Perform chest physiotherapy prior to suctioning.

Chest physiotherapy techniques, such as percussion and vibration, can help to mobilize secretions in the lungs and airways. While this may indirectly assist in clearing secretions, it does not directly address the issue of thinning the secretions, which is the primary concern in this scenario.

C. Prelubricate the suction catheter tip with sterile saline when suctioning the airway.

Prelubricating the suction catheter tip with sterile saline before suctioning can help reduce friction and potential trauma to the airway. While this can be beneficial for airway management, it does not directly address the need to thin copious and tenacious secretions.

D. Hyperventilate the client with 100% oxygen before suctioning the airway.

Hyperventilating the client with 100% oxygen before suctioning is not recommended. It can lead to respiratory alkalosis, which is a condition characterized by decreased levels of carbon dioxide in the blood. This can worsen the client's condition and may lead to adverse effects. Additionally, it does not directly address the need to thin secretions.

A. Frequent oral hygiene is necessary B. The inhaler should be used on a PRN basis only C. Rinse and spit after inhalation of the medication D. When taking a steroid drug as well as a bronchodilator, the bronchodilator should be administered first E. Hold your breath for 10 seconds during inhalation of the medication

Correct Answer is ["A","C","D","E"]

Explanation

Correct Answers:

A. Frequent oral hygiene is necessary:Steroid inhalers can increase the risk of oral thrush and other infections, so maintaining good oral hygiene is essential to minimize this risk.

C. Rinse and spit after inhalation of the medication:Rinsing the mouth and spitting after using a steroid inhaler helps to remove residual medication and reduce the risk of developing oral thrush.

D. When taking a steroid drug as well as a bronchodilator, the bronchodilator should be administered first:Administering a bronchodilator first helps open the airways, allowing the steroid medication to reach deeper into the lungs for more effective treatment.

E. Hold your breath for 10 seconds during inhalation of the medication:Holding the breath allows for better medication absorption in the lungs.

Incorrect Answer:

B. The inhaler should be used on a PRN basis only:Steroid inhalers are typically used on a regular schedule for long-term control of asthma or other respiratory conditions, rather than on a PRN (as needed) basis. PRN use is more applicable to rescue inhalers, like short-acting bronchodilators.
