A nurse is caring for a client who has dyspnea with an oxygen saturation of 88%. Which of the following indicates the type of face mask the nurse should use to deliver the client a 90% oxygen concentration?
Simple face mask
Nasal prongs
Non-rebreather mask
Nasal cannula
The Correct Answer is C
A. Simple face mask: This can deliver oxygen at flow rates of 5-10 liters per minute and typically provides an oxygen concentration of about 35-50%.
B. Nasal prongs: Nasal prongs deliver oxygen at lower flow rates and may not be sufficient to raise the client's oxygen saturation to 90%.
C. Non-rebreather mask: This mask can deliver high concentrations of oxygen (up to 90-100%) at flow rates of 10-15 liters per minute. It has one-way valves to prevent the patient from rebreathing exhaled air, thus maximizing the delivery of oxygen.
D. Nasal cannula: Nasal cannulas deliver oxygen at lower flow rates (typically up to 6 liters per minute) and may not provide the necessary concentration to achieve an oxygen saturation of 90%.

Explanation
In the scenario provided, the nurse should take further action based on the following findings: The client's distended abdomen, reports of nausea, and coughing suggest possible intolerance to the tube feedings or another complication. A gastric residual volume of 550 mL is significantly higher than the standard safe limit of 500 mL, indicating delayed gastric emptying or feeding intolerance. The pH of gastric aspirate at 4.5 is within normal limits, suggesting that the tube is likely placed correctly. However, the elevated heart rate of 110/min could be a response to discomfort or underlying stress. The pulse oximetry reading of 90% on room air is below the normal range, which typically is 95-100%, indicating potential impaired gas exchange or early signs of respiratory distress. These findings warrant immediate nursing interventions and possibly a reassessment of the feeding regimen, along with measures to improve the client's respiratory function and comfort. It is essential to monitor for further signs of aspiration, respiratory distress, or other complications, and to communicate these findings to the healthcare team for appropriate management.
Correct Answer is ["A","B","E","F"]
Explanation
A. The use of separate cutting boards for raw meats and vegetables is a fundamental food safety practice to prevent cross-contamination. On Day 14, the client demonstrates an
understanding of this by using one cutting board for raw meats and a different one for vegetables.
B. Increasing the handwashing time from 10 seconds to 15 seconds is in line with food safety guidelines, which recommend washing hands for at least 20 seconds to effectively remove germs.
C. Additionally, there was no information provided on the time leftovers sat unrefrigerated on the countertop, which should be minimized to prevent bacterial growth.
D. The client did not demonstrate an understanding of safe refrigerator temperatures as the temperature did not meet the recommended setting of 4° C (40° F) or below.
E. Defrosting frozen foods in the refrigerator is a safe practice to prevent the growth of harmful bacteria, which can occur when foods are defrosted on the countertop.
F. Discarding leftovers after 2 days minimizes the risk of foodborne illnesses, as the longer food is stored, even in the refrigerator, the higher the risk of bacterial growth.
