The nurse explains that the medication Prostaglandin E1 is being given to their child with transposition of the great vessels to:
Decrease pulmonary congestion
Stimulate the production of red blood cells
Keep the ductus arteriosus open.
Increase blood flow to the system
The Correct Answer is C
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.

Correct Answer is ["A","B","D","E"]
Explanation
A. Fever: Osteomyelitis is often associated with fever as it is an infectious process that can cause an elevated body temperature.
B. Unwillingness to move the affected extremity: Children with osteomyelitis may experience pain and discomfort, leading to a reluctance to move the affected limb.
C. A previous closed fracture of an extremity is not typically a direct assessment finding for osteomyelitis. Osteomyelitis is more commonly associated with infections that can spread to the bone, and a previous fracture may not always be present.
D. Redness and swelling at the site: Osteomyelitis can cause local inflammation, leading to redness and swelling at the affected area.
E. Severe pain: Pain is a common symptom of osteomyelitis, and it can be severe, leading to the child's unwillingness to move the affected extremity.
Correct Answer is ["A","C","E"]
Explanation
A. Fatigue: Children with ALL often experience fatigue and weakness due to decreased red blood cell and platelet production as a result of bone marrow involvement by leukemia cells.
C. Pallor: Pallor, or paleness, is a common finding in children with ALL because of anemia (reduced red blood cell count).
E. Multiple bruises: Children with ALL may have an increased tendency to bruise and bleed due to low platelet counts, making them susceptible to easy bruising and petechiae.
The other options, B (Generalized edema) and D (Jaundice), are not typical clinical findings associated with ALL. Generalized edema is not a common symptom, and jaundice (yellowing of the skin and eyes) is more commonly associated with liver conditions, not leukemia.
