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. Inspecting the mouth weekly for ulcerations is not sufficient. Children receiving chemotherapy should be encouraged to perform daily oral care, and any concerning symptoms should be reported promptly to the healthcare provider.

B. Using a potent commercial mouthwash is not recommended, as many commercial mouthwashes contain alcohol or other potentially irritating ingredients. A healthcare provider should recommend a suitable oral rinse if needed.

C. Clean the teeth manually with a soft toothbrush.

Children receiving chemotherapy are at risk of developing mouth sores (mucositis) and other oral complications. It is essential to maintain good oral hygiene to minimize the risk of infection and reduce discomfort. Using a soft toothbrush for gentle manual cleaning is recommended, as it helps to prevent injury to the sensitive oral tissues that can occur with a hard toothbrush.

D. Visiting a dental professional only during episodes of excessive bleeding or pain is not recommended. Regular dental check-ups are important for children receiving chemotherapy to monitor and address oral health issues. Waiting for symptoms of bleeding or pain may result in a delay in addressing potential problems.

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.
