A nurse is caring for a client who has pneumonia with dyspnea. The client's ABG results are pH 7.30, PaCO2 50 mm Hg, HCO3 26 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?
Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is B
This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.
A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.
C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.
D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.
Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).

Correct Answer is D
Explanation
The correct answer is choice D. Requires nasogastric suction.
Nasogastric suction removes gastric secretions that contain potassium, leading to a loss of potassium from the body.
This can cause hypokalemia, which is a low level of potassium in the blood.
Choice A is wrong because Addison’s disease causes hyperkalemia, which is a high level of potassium in the blood.
Choice B is wrong because tissue damage can release potassium from the cells into the blood, causing hyperkalemia.
Choice C is wrong because uric acid level is not related to potassium level.
Uric acid is a waste product of purine metabolism that can cause gout or kidney stones if elevated.
Correct Answer is C
Explanation
The correct answer is choice C. Place white tape on the edges of stairs.
Choice A rationale:
While having the furnace inspected is important for safety, it should be done annually, not every two years.Regular inspections help prevent carbon monoxide leaks and ensure the furnace is functioning properly.
Choice B rationale:
Running wires and cords under carpeting is a safety hazard. It can lead to overheating and potentially cause a fire.Additionally, it creates a tripping hazard.
Choice C rationale:
Placing white tape on the edges of stairs is a recommended safety measure.It increases visibility, especially for older adults who may have vision impairments, reducing the risk of falls.
Choice D rationale:
Placing area rugs on wooden floors can be dangerous as they can slip and cause falls.If area rugs are used, they should be secured with non-slip backing or tape.
