A nurse is preparing to administer albuterol syrup 1.6 mg PO tid. Available is albuterol 2 mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
Formula:
Volume to administer (mL) = (Desired dose (mg) / Available concentration (mg/mL))
Desired dose = 1.6 mg
Available concentration = 2 mg / 5 mL
Calculate the concentration per mL:
2 mg / 5 mL = 0.4 mg/mL
Volume to administer = 1.6 mg / 0.4 mg/mL
= 4 mL
The nurse should administer 4 mL per dose.

Correct Answer is C
Explanation
A. Conduct a study about the time and money costs of implementing the change. While analyzing costs and time efficiency is important for evaluating resource utilization, it does not directly measure the effectiveness of the changes in reducing medication errors. The primary goal of quality improvement is to assess patient safety outcomes rather than financial impact alone.
B. Establish a benchmark to identify a standard of performance. Setting benchmarks is a useful strategy for quality control, but it is a preliminary step in the evaluation process. Benchmarks provide a target for improvement, but they do not measure whether the specific changes implemented have led to a reduction in medication errors.
C. Compare the number of medication errors before and after the action was implemented. The most effective way to evaluate the success of the changes is to analyze pre- and post-intervention data. Comparing the frequency of medication errors before and after the quality improvement measures allows for an objective assessment of whether the interventions have led to a meaningful reduction in errors.
D. Provide the staff with a questionnaire to quantify staff satisfaction with the changes. Staff feedback is valuable for assessing workflow and morale, but it does not directly measure the effectiveness of the intervention in reducing medication errors. A reduction in actual error rates provides a more concrete evaluation of the intervention’s success.
Correct Answer is A
Explanation
A. Incentive spirometry: This is the most effective independent nursing measure to prevent atelectasis. Incentive spirometry encourages deep breathing and lung expansion, which helps to keep the alveoli open and reduces the risk of collapse. It is particularly beneficial for clients at risk for atelectasis, such as those who have had surgery, are immobile, or have respiratory issues. Regular use of the incentive spirometer promotes optimal lung function and helps prevent the development of atelectasis.
B. Increase oral fluid intake: While maintaining adequate hydration is important for overall health and can help thin secretions, it is not as directly effective in preventing atelectasis as incentive spirometry. Increased fluid intake alone does not promote deep breathing or lung expansion, which are critical in preventing airway collapse.
C. Ambulation: Although ambulation is an important intervention for promoting overall mobility and respiratory function, it may not be as practical for all clients, especially those who are unable to move independently. While getting the client up and moving can help prevent atelectasis, the most immediate and effective measure remains the use of incentive spirometry, which can be performed regardless of the client’s mobility status.
D. Oxygen therapy: While oxygen therapy can help improve oxygenation in clients with respiratory issues, it does not directly prevent atelectasis. Providing supplemental oxygen does not address the need for lung expansion and deep breathing, which are essential in maintaining alveolar patency. Therefore, oxygen therapy should not be prioritized as the primary independent measure to prevent atelectasis.
