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 C
Explanation
A. Dress the child in woolen clothes during cold months: Wool can be irritating to the skin and may worsen eczema symptoms. Cotton or soft fabrics are typically better choices.
B. Launder the child's clothing with fabric softener: Fabric softeners often contain chemicals that can irritate the skin. It's best to use fragrance-free and hypoallergenic detergents and skip fabric softeners.
C. Apply a topical corticosteroid ointment to the affected area.
When teaching a parent of a preschooler with eczema, it's essential to provide guidance on appropriate treatments. Applying a topical corticosteroid ointment is an effective approach for managing eczema symptoms. These medications can help reduce inflammation and itching, which are common in eczema. However, it's crucial for the parent to use them as directed by a healthcare provider and not excessively.
D. Give the child a bubble bath every day: Frequent bathing, especially with bubble baths, can dry out the skin and worsen eczema. It's usually better to limit baths and use gentle, fragrance-free cleansers.
Correct Answer is B
Explanation
A. Positive Western blot test: A positive Western blot test confirms HIV infection but doesn't provide information about the current immune status or progression of the disease.
B. CD4-T-cell count 180 cells/mm³.
The CD4-T-cell count is a crucial indicator of a person's immune system function, and it's a primary marker used to monitor the progression of HIV infection. A CD4 count of 180 cells/mm³ is significantly below the normal range (which is typically higher), indicating immunosuppression and an increased risk of opportunistic infections. Maintaining and improving immune function is a top priority in the care of clients with HIV.
C. Platelets 150,000/mm³: Platelet counts are important, but they are not the primary indicator for assessing the progression of HIV.
D. WBC 5.000/mm³: The white blood cell count (WBC) is important for assessing overall immune function, but it doesn't provide the same specific information about the immune system status as the CD4-T-cell count.
