A nurse is reviewing the ABG results of a client who has COPD. The results include a pH of 7.3 (7.35 to 7.45), PaO2 56 mm Hg (80 to 100 mm Hg), PaCO2 54 mm Hg (35 to 45 mm Hg), HCO3- 26 mEq/L (21 to 28 mEq/L), and SaO2 87%. Which of the following is the correct interpretation of these values?
Compensated metabolic acidosis
Compensated respiratory acidosis
Uncompensated respiratory acidosis
Uncompensated metabolic acidosis
The Correct Answer is C
Rationale:
A. Compensated metabolic acidosis would show a normal pH with a decrease in HCO3- and a decrease in PaCO2.
B. Compensated respiratory acidosis would show a normal pH with an elevated PaCO2 and a compensatory increase in HCO3-.
C. The low pH indicates acidosis, and the elevated PaCO2 suggests that it is respiratory in origin, with the HCO3- remaining normal, indicating no compensation has occurred yet.
D. Uncompensated metabolic acidosis would present with a low pH, low HCO3-, and normal PaCO2.

Correct Answer is C
Explanation
Rationale:
A. Selecting a quiet location is important, but first, it is essential to assess the client's current state and the surrounding environment.
B. Providing options can help empower the client, but it is best to first observe the client to gauge their level of agitation and determine the appropriate response.
C. Observing the client and the situation allows the nurse to understand the severity of the agitation and the context, which is critical for making informed decisions about the next steps.
D. Respecting personal space is important, but it should follow an assessment of the situation to ensure safety for both the client and staff.
Correct Answer is A
Explanation
Rationale:
A. Having the client wear a surgical mask while being transported outside the room is essential to prevent the transmission of TB to others. This minimizes exposure to airborne droplets.
B. Wearing a surgical mask while providing care for the client is not sufficient for preventing TB transmission; an N95 respirator is required to protect healthcare workers from inhaling airborne particles.
C. While restricting visitors may help limit exposure, it is not the most effective preventive measure compared to ensuring that the client wears a mask when out of their room.
D. Initiating contact precautions is not necessary for TB, as it primarily requires airborne precautions. Airborne isolation precautions should be followed, including the use of N95 respirators for healthcare workers and appropriate ventilation.
