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 D
Explanation
A. Limit oral fluids to minimize labored breathing: This action is not appropriate, as adequate hydration is important for thinning mucus secretions, making it easier for the client to expectorate them. Limiting fluids could lead to thicker secretions, which may worsen the client’s respiratory distress and increase the difficulty of clearing secretions. Therefore, this approach is not suitable for a client with pneumonia and respiratory compromise.
B. Perform pursed-lip breathing to expel trapped carbon dioxide from the alveoli: While pursed-lip breathing can help with exhalation and improve oxygenation, it does not directly address the need to mobilize and clear copious secretions. This technique is beneficial in managing dyspnea and improving ventilation but is not the priority action when the client has significant secretions that need to be cleared.
C. Lie in a low Fowler's position to promote lung expansion: A low Fowler's position (30 degrees) is less effective for promoting lung expansion compared to higher Fowler's positions. Semi-Fowler's (30-45 degrees) or high Fowler's (greater than 45 degrees) positions are more beneficial for improving lung expansion and facilitating breathing in clients with respiratory distress. Therefore, this option does not provide the most effective intervention for the client's condition.
D. Perform hourly incentive spirometry to inflate lungs and mobilize secretions: This is the priority action for the nurse to encourage, as incentive spirometry is specifically designed to help inflate the lungs and improve lung function. It promotes deep breathing, which can enhance ventilation, prevent atelectasis, and facilitate the mobilization of secretions. Regular use of incentive spirometry is essential in managing pneumonia and can significantly improve respiratory outcomes for the client.
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.
