The Correct Answer is A
A. Chvostek's sign is a clinical sign observed during physical examination that may indicate hypocalcemia. It is elicited by tapping or lightly striking the facial nerve just anterior to
the earlobe, which can cause twitching of the facial muscles, particularly the muscles around the mouth and nose.
B. This image shows winging of the scapula. Winging of the scapula, also known as
scapular winging, is a condition characterized by the abnormal protrusion or prominence of the scapula away from the back wall of the thorax. Normally, the scapula lies flat
against the rib cage, providing stability and support for arm movements.

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.
Correct Answer is C
Explanation
A. This technique is used for children, not adults. To straighten the ear canal for adults, the pinna should be pulled upwards and back.
B. Cleansing the outer ear with isopropyl alcohol is not typically necessary before administering otic medication and may cause irritation to the delicate skin of the ear canal.
C. Holding the dropper 1 cm away allows for better control and accuracy when directing the medication droplets into the ear canal. This helps ensure the medication reaches the intended area within the middle ear. Holding the dropper too close could accidentally touch the ear canal or eardrum, causing discomfort or even injury. Maintaining a slight distance helps prevent the dropper tip from contaminating the ear canal with skin flora from the client or the nurse's hand.
D. While some otic medications might recommend staying still for a short time after administration, 10 minutes is an excessive timeframe for most medications.
