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 C
Explanation
Choice A reason: Eliminating egg whites from the diet is not necessary, as they are a good source of protein and do not contain any fat or cholesterol. The client should limit or avoid egg yolks, which are high in cholesterol and saturated fat.
Choice B reason: Using coconut oil when preparing food is not advisable, as it is a source of saturated fat that can raise blood cholesterol levels and increase the risk of atherosclerosis and heart disease. The client should use unsaturated fats, such as olive oil or canola oil, which can lower blood cholesterol levels and improve heart health.
Choice C reason: Eating fish three times a week is a good practice, as fish are rich in omega-3 fatty acids that can reduce inflammation, lower blood pressure, and prevent blood clots that can cause heart attacks or strokes. The client should choose oily fish, such as salmon, tuna, or mackerel, which have higher amounts of omega-3 fatty acids.
Choice D reason: Including 2 percent milk in the diet is not recommended, as it contains more fat and calories than skim or 1 percent milk. The client should choose low-fat or fat-free dairy products, such as yogurt, cheese, or milk, which can provide calcium and protein without excess fat.
Correct Answer is D
Explanation
Choice A reason: Prone position is not appropriate for a paracentesis, as it can compress the abdominal organs and make it difficult to access the peritoneal cavity.
Choice B reason: Knees elevated position is not appropriate for a paracentesis, as it can increase the intra-abdominal pressure and reduce the amount of fluid that can be drained.
Choice C reason: Lithotomy position is not appropriate for a paracentesis, as it can expose the genital area and increase the risk of infection or injury.
Choice D reason: Leaning forward position is appropriate for a paracentesis, as it can shift the abdominal organs upward and allow more space for the needle insertion and fluid drainage.
