An infant is experiencing dyspnea related to patent ductus arteriosus (PDA). The nurse understands dyspnea occurs because blood

A. Appropriate dose of aspirin and rest: Aspirin is an antiplatelet medication that can worsen bleeding in individuals with hemophilia. It should be avoided. Rest alone is not sufficient in this situation.

B. Immobilization of the leg and a dose of ibuprofen: Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding. Immobilizing the leg may help prevent further injury, but it does not address the underlying bleeding issue or provide the necessary clotting factor.

C. Heating pad and administration of factor VIII concentrate: While the administration of factor VIII concentrate is appropriate, the use of a heating pad is not advisable, as it can potentially worsen bleeding by dilating blood vessels in the area.

D. Pressure on the site and administration of the required clotting factor.

Hemophilia is a bleeding disorder in which the blood doesn't clot properly. When a hemophilic child has a significant bruise or bleeding, it is crucial to administer the specific clotting factor that they are deficient in (Factor VIII or IX) to stop the bleeding. Applying pressure to the site can also help control bleeding.

In summary, option D is the priority because it directly addresses the bleeding issue in the child with hemophilia by applying pressure to the site and administering the necessary clotting factor. This is crucial in preventing further bleeding and complications.

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.
