The nurse is conducting discharge teaching about signs and symptoms of heart failure to parents of an infant with a repaired tetralogy of Fallot. Which signs and symptoms should the nurse include? (Select all that apply.)

The correct answer is choice C.

Choice C rationale:

Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.

Choice A rationale:

Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.

Choice B rationale:

Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.

Choice D rationale:

Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.

Answer is: d. Apply direct pressure above the catheterization site.

Explanation: The first action should be to apply direct pressure above the catheterization site to help control the bleeding and minimize blood loss. This will also give the nurse time to prepare additional interventions or supplies if necessary.

Choice a. is wrong because placing the child in the Trendelenburg position is not an appropriate initial nursing action in this scenario. This position can increase intracranial pressure and is typically used for patients experiencing shock or hypotension.

Choice b. is wrong because applying a new bandage with more pressure might be a subsequent action, but the priority is to apply direct pressure to slow down the bleeding.

Choice c. is wrong because notifying the physician is important, but the nurse should first take immediate action to control the bleeding and minimize potential harm to the patient.
