A nurse is reviewing the arterial blood gas (ABG) results for a patient diagnosed with progressive Chronic Obstructive Pulmonary Disease (COPD). Which ABG results should the nurse expect for a patient with progressive COPD?

pH 7.55, PaCO2 30 mm Hg, PaO2 80 mm Hg, HCO3 24 mEq/L

pH 7.40, PaCO2 40 mm Hg, PaO2 94 mm Hg, HCO3 22 mEq/L

pH 7.30, PaCO2 60 mm Hg, PaO2 70 mm Hg, HCO3 30 mEq/L

pH 7.38, PaCO2 45 mm Hg, PaO2 88 mm Hg, HCO3 26 mEq/L .

Answer and Explanation

The Correct Answer is C

Choice A rationale
A pH of 7.55, PaCO2 of 30 mm Hg, PaO2 of 80 mm Hg, and HCO3 of 24 mEq/L would indicate respiratory alkalosis, which is not typically associated with progressive COPD67.
Choice B rationale
A pH of 7.40, PaCO2 of 40 mm Hg, PaO2 of 94 mm Hg, and HCO3 of 22 mEq/L represent normal ABG values.
Choice C rationale
A pH of 7.30, PaCO2 of 60 mm Hg, PaO2 of 70 mm Hg, and HCO3 of 30 mEq/L are indicative of respiratory acidosis with metabolic compensation, which is commonly seen in patients with progressive COPD67.
Choice D rationale
A pH of 7.38, PaCO2 of 45 mm Hg, PaO2 of 88 mm Hg, and HCO3 of 26 mEq/L would indicate a slight respiratory acidosis, which is not typically associated with progressive COPD67.

Correct Answer is ["10"]

Explanation

Step 1 is to determine the amount of cefaclor in each milliliter of the oral suspension. This is done by dividing the total amount of cefaclor in the suspension (250 mg) by the total volume of the suspension (5 mL). So, 250 mg ÷ 5 mL = 50 mg/mL.

Step 2 is to calculate the volume of the suspension that contains the prescribed dose of cefaclor (500 mg). This is done by dividing the prescribed dose by the amount of cefaclor in each milliliter of the suspension. So, 500 mg ÷ 50 mg/mL = 10 mL. Therefore, the nurse should administer 10 mL of the cefaclor oral suspension per dose.

A. Establish a benchmark to identify a standard of performance. B. Compare the number of medication errors before and after the implementation of the measures. C. Conduct a study on the time and cost implications of implementing the change. D. Provide a Questionnaire to the staff to quantify their satisfaction with the changes.

Correct Answer is B

Explanation

Choice A rationale
Establishing a benchmark to identify a standard of performance is a crucial step in any quality improvement process. It provides a reference point against which progress can be measured. However, it does not directly evaluate the effectiveness of the implemented measures.
Choice B rationale
Comparing the number of medication errors before and after the implementation of the measures is the most direct and effective method to evaluate the success of the changes. This method provides quantitative data that can clearly show whether the measures have led to a reduction in medication errors.
Choice C rationale
Conducting a study on the time and cost implications of implementing the change can provide valuable information about the efficiency of the measures. However, it does not directly assess their effectiveness in reducing medication errors.
Choice D rationale
Providing a questionnaire to the staff to quantify their satisfaction with the changes can help to assess the acceptance of the measures among the staff. However, staff satisfaction does not necessarily correlate with the effectiveness of the measures in reducing medication errors.
