A nurse is caring for a client who has pneumonia with dyspnea. The client's ABG results are pH 7.30, PaCO2 50 mm Hg, HCO3 26 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?
Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is B
This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.
A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.
C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.
D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.
Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).

Correct Answer is A
Explanation
The correct answer is: Choice A: Maintain direct pressure over the site.
Here's the rationale for each choice:
- Choice A: Maintain direct pressure over the site (CORRECT) This is the most important initial step in controlling bleeding for any patient, especially one with hemophilia who has a deficiency in clotting factors. Maintaining pressure directly on the wound helps to form a clot and stop the bleeding.
- Choice B: Check whether the bleeding has stopped While checking for bleeding cessation is important, it shouldn't be the immediate next step after applying a dressing. Maintaining pressure ensures the dressing remains effective. Once pressure is released, you can assess for continued bleeding.
- Choice C: Obtain a radial pulse Assessing the radial pulse is not directly related to managing the bleeding from the laceration. While it's a vital sign, it's not a priority in this situation.
- Choice D: Reinforce the dressing over the site While reinforcing the dressing might be necessary later if it becomes saturated with blood, maintaining direct pressure is the crucial first step.
Correct Answer is C
Explanation
Red streaks along the incision. This is a possible sign of infection and should be reported to the healthcare provider. A temperature of 37.2°C (99°F) is within the normal range and does not require reporting. Serosanguineous drainage at the incision site is normal within the first few days postoperatively. Hypoactive bowel sounds in all four quadrants can indicate ileus, which is a possible complication following abdominal surgery, but it is not an immediate concern and can be monitored unless other symptoms arise.
