Answer and Explanation

Correct Answer : A,B,E,F

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.

Correct Answer is A

Explanation

A. Ensure that the stool specimen does not contain urine: Fecal occult blood tests are designed to detect blood in the stool, so it's important to ensure that the specimen
collected is not contaminated with urine, which could yield a false-positive result.

B. Wear sterile gloves when handling the stool specimen: Sterile gloves are not typically required for handling stool specimens for fecal occult blood testing. Standard
precautions, including hand hygiene and wearing non-sterile gloves, are sufficient.

C. Repeat the test three times using the same stool specimen: The test is typically
performed once on a fresh stool specimen, and repeating the test with the same specimen is not recommended.
D. Have the client defecate into a bedpan that contains a small amount of water: Fecal occult blood testing requires a small sample of stool collected from a bowel movement. Using a bedpan with water may dilute the stool and affect the accuracy of the test.

A. Simple face mask B. Nasal prongs C. Non-rebreather mask D. Nasal cannula

Correct Answer is C

Explanation

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%.
