A nurse is preparing to administer levothyroxine 0.175 mg PO once a day. The amount available is levothyroxine 88 mcg/tablet. How many tablets 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)

A. Introducing new foods every day does not allow sufficient time to monitor for adverse reactions.

B. Waiting 8 to 10 days between introducing new foods is a longer interval than typically recommended. It may unnecessarily delay the introduction of a variety of foods to the infant's diet.

C. 5 to 7 days.

When introducing new foods to an infant, it's important to do so gradually to monitor for any potential allergic reactions or sensitivities. Waiting 5 to 7 days between introducing new foods allows for observation of any adverse reactions, such as allergies or digestive issues. This approach helps in identifying the specific food responsible for any adverse reactions and ensures the infant's safety.

D. Waiting 2 to 3 days is too short of an interval to adequately monitor for adverse reactions. Waiting 5 to 7 days provides a better balance between introducing new foods and monitoring for potential issues.

In transposition of the great vessels (TGV), the aorta and the pulmonary artery are switched, causing oxygen-rich blood to be pumped back to the lungs and oxygen-poor blood to be pumped out to the body. The ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, allows blood to mix between the two circulations.

Prostaglandin E1 is used to keep the ductus arteriosus open, allowing for a controlled mixing of oxygenated and deoxygenated blood, which can improve oxygen delivery to the body in cases of TGV. This helps maintain oxygenation until corrective surgical interventions can be performed.

The other options, A (decrease pulmonary congestion), B (stimulate the production of red blood cells), and D (increase blood flow to the system), do not accurately describe the primary purpose of Prostaglandin E1 in the context of TGV. The main goal is to maintain a pathway for oxygenated blood to mix with deoxygenated blood to improve oxygen delivery to the body.
