A client has a nasogastric (NG) tube placed during abdominal surgery. During postoperative convalescence, which arterial blood gas values are consistent with metabolic alkalosis?
pH 7.49, PCO₂ 45 mm Hg, HCO₃ 32 mEq/L (32 mmol/L), PO₂ 90 mm Hg.
pH 7.30, PCO₂ 20 mm Hg, HCO₃ 22 mEq/L (22 mmol/L), PO₂ 85 mm Hg.
pH 7.46, PCO₂ 55 mm Hg, HCO₃ 36 mEq/L (36 mmol/L), PO₂ 95 mm Hg.
pH 7.29, PCO₂ 35 mm Hg, HCO₃ 25 mEq/L (25 mmol/L), PO₂ 99 mm Hg.
The Correct Answer is A
Choice A rationale
pH 7.49, PCO₂ 45 mm Hg, HCO₃ 32 mEq/L (32 mmol/L), PO₂ 90 mm Hg indicates metabolic alkalosis. The elevated pH and HCO₃ levels are consistent with this condition.
Choice B rationale
pH 7.30, PCO₂ 20 mm Hg, HCO₃ 22 mEq/L (22 mmol/L), PO₂ 85 mm Hg indicates metabolic acidosis with respiratory compensation, not metabolic alkalosis.
Choice C rationale
pH 7.46, PCO₂ 55 mm Hg, HCO₃ 36 mEq/L (36 mmol/L), PO₂ 95 mm Hg indicates metabolic alkalosis with respiratory compensation. However, the pH is slightly lower than in Choice A, making Choice A more indicative of metabolic alkalosis.
Choice D rationale
pH 7.29, PCO₂ 35 mm Hg, HCO₃ 25 mEq/L (25 mmol/L), PO₂ 99 mm Hg indicates metabolic acidosis, not metabolic alkalosis.

Correct Answer is D
Explanation
Choice A rationale
Storing the medication at room temperature is appropriate for ipratropium inhalers. This ensures the medication remains effective and safe for use.
Choice B rationale
Attaching a spacer device to the inhaler is recommended for patients using ipratropium inhalers. A spacer helps deliver the medication more effectively to the lungs and reduces the risk of side effects.
Choice C rationale
Rinsing the mouth after each use of the inhaler is a good practice to prevent oral thrush and other side effects. It is a recommended step in the proper use of inhalers.
Choice D rationale
Priming the inhaler with 7 pumps is excessive. Typically, inhalers need to be primed with 2-4 pumps before first use or if they haven’t been used for a while. Over-priming can waste medication and indicate a need for additional teaching.
Correct Answer is B
Explanation
Choice A rationale
Decreasing speaking speed may help with clarity, but it does not address the issue of hearing loss.
Choice B rationale
Over-enunciating word syllables can help the client understand speech better, especially if they have hearing difficulties. This technique makes it easier for the client to read lips and understand spoken words.
Choice C rationale
Raising voice volume to a shout can be uncomfortable and may not improve understanding. It can also be perceived as rude or aggressive.
Choice D rationale
Exaggerating nonverbal expressions may help with communication, but it is not as effective as over-enunciating word syllables for clients with hearing difficulties.
