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 reason: Changed mental status, such as confusion, agitation, or delirium, can be a sign of a bladder infection in older adults, as they may not have the typical symptoms of dysuria, frequency, or urgency.
Choice B reason: WBC count 9,000/mm³ is within the normal range of 4,500 to 11,000/mm³ and does not indicate an infection.
Choice C reason: Diminished reflexes are not related to a bladder infection and may be due to aging, neurological disorders, or medication side effects.
Choice D reason: Temperature 37.3°C (99.1°F) is slightly elevated but not indicative of a bladder infection. Older adults may have lower baseline temperatures and may not develop fever in response to an infection.
Correct Answer is B
Explanation
Choice A reason: Having a bologna sandwich is not a good choice for a client who has hypertension, as bologna is a processed meat that contains high amounts of sodium and saturated fat, which can raise blood pressure and cholesterol levels.
Choice B reason: Seasoning food with vinegar is a good choice for a client who has hypertension, as vinegar is a low-sodium condiment that can add flavor and acidity to food without increasing blood pressure.
Choice C reason: Seasoning food with ketchup is not a good choice for a client who has hypertension, as ketchup is a high-sodium condiment that can increase blood pressure and fluid retention.
Choice D reason: Having canned soup is not a good choice for a client who has hypertension, as canned soup is a high-sodium food that can increase blood pressure and fluid retention. The client should choose low-sodium or homemade soup instead.
