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 A
Explanation
Choice A: This is correct. Phototherapy is a treatment option for psoriasis that involves exposing the skin to ultraviolet light, which can reduce inflammation and slow down the growth of skin cells.
Choice B: This is incorrect. Oil-based ointment is not recommended for psoriasis, as it can clog the pores and worsen the condition.
Choice C: This is incorrect. Dermabrasion is a cosmetic procedure that involves removing the outer layer of skin with a rotating device, which can cause bleeding, infection, and scarring.
Choice D: This is incorrect. Benzoyl peroxide is an acne medication that can dry out and irritate the skin, which can aggravate psoriasis.
Correct Answer is B
Explanation
Choice A: This is incorrect because feeling bloated after the procedure is not a reason to call the doctor. Feeling bloated after a colonoscopy is normal due to air being introduced into the colon during the procedure. The client can relieve bloating by passing gas or walking.
Choice B: This is correct because making arrangements for a ride home indicates an understanding of the procedure. The client will receive sedation during a colonoscopy, which can impair their judgment and coordination. The client should not drive or operate machinery until fully recovered from sedation.
Choice C: This is incorrect because eating a light breakfast the morning of the procedure indicates a lack of understanding of the procedure. The client should have nothing by mouth after midnight before a colonoscopy, unless instructed otherwise by the provider. The client should follow a clear liquid diet and take bowel preparation agents as prescribed before the procedure.
Choice D: This is incorrect because having a sore throat from the breathing tube indicates a lack of understanding of the procedure. The client will not have a breathing tube during a colonoscopy, as it does not involve intubation or ventilation. The client may have a mouth guard or bite block to protect their teeth and prevent biting on the endoscope.
