A nurse is reviewing the ABG values of a client who has pneumonia. Which of the following findings indicates the client is developing respiratory acidosis?
PaO2 85 mmHg
pH 7.47
HCO3 25 mEq/L
PaCO2 55 mmHg
The Correct Answer is D
Choice A reason: PaO2 85 mmHg is within the normal range of 80 to 100 mmHg and does not indicate any hypoxemia or oxygen deficiency.
Choice B reason: pH 7.47 is within the normal range of 7.35 to 7.45 and does not indicate any acid-base imbalance.
Choice C reason: HCO3 25 mEq/L is within the normal range of 22 to 26 mEq/L and does not indicate any metabolic disturbance.
Choice D reason: PaCO2 55 mmHg is above the normal range of 35 to 45 mmHg and indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pneumonia, which can impair gas exchange and ventilation.

Correct Answer is B
Explanation
Choice A: This is incorrect. The nurse should don clean gloves before removing the dressing, and then change to sterile gloves before applying the new dressing.
Choice B: This is correct. The nurse should offer the client pain medication before the procedure, as changing a dressing for a stage III pressure ulcer can be very painful.
Choice C: This is incorrect. The nurse should prepare the sterile dressing supplies just before the dressing change, not 30 min before, to prevent contamination.
Choice D: This is incorrect. The nurse should not disinfect the wound bed with alcohol, as this can damage the healthy tissue and delay healing. The nurse should use a saline solution or an antiseptic solution as prescribed.
Correct Answer is A
Explanation
Choice A reason: Using analgesia around the clock is an appropriate action. The nurse should follow the principle of prevention rather than rescue when managing pain for a client who has terminal cancer. The nurse should administer analgesics on a regular schedule to maintain a steady level of pain relief and prevent breakthrough pain.
Choice B reason: Applying pain patches each morning and removing them at bedtime is not an appropriate action. The nurse should follow the manufacturer's instructions for applying and removing pain patches. Some patches are designed to be worn for 24 hours, while others are worn for 72 hours. Removing the patches too soon can cause inadequate pain control and withdrawal symptoms.
Choice C reason: Using intramuscular medications to control pain is not an appropriate action. The nurse should avoid using intramuscular route for administering analgesics to a client who has terminal cancer. Intramuscular injections are painful, unreliable, and increase the risk of infection and bleeding. The nurse should use oral, transdermal, or subcutaneous routes whenever possible.
Choice D reason: Decreasing a medication dose if the client develops tolerance is not an appropriate action. The nurse should understand that tolerance is a normal physiological response to long-term opioid use and does not indicate addiction or abuse. The nurse should adjust the medication dose according to the client's level of pain and response to treatment.
