The registered nurse is discussing care of an infant diagnosed with a patent ductus arteriosus (PDA) with a nursing student. The registered nurse determines that the nursing student needs further teaching regarding a PDA when the student states that which circulatory change is a characteristic of this disorder?
This shunting allows oxygenated and unoxygenated blood to mix.
Blood is shunted to the right side of the heart.
This shunting results in increased pulmonary blood flow.
Blood is shunted to the left side of the heart.
The Correct Answer is D
A. "This shunting allows oxygenated and unoxygenated blood to mix."
Explanation: This statement is correct. In PDA, the shunting of blood between the aorta and pulmonary artery allows oxygenated and unoxygenated blood to mix, leading to decreased oxygen saturation in the systemic circulation.
B. "Blood is shunted to the right side of the heart."
Explanation: This statement is correct. In PDA, blood is shunted from the left side of the heart (aorta) to the right side of the heart (pulmonary artery).
C. "This shunting results in increased pulmonary blood flow."
Explanation: This statement is correct. PDA leads to increased pulmonary blood flow as a result of the shunting of blood from the aorta to the pulmonary artery.
D. "Blood is shunted to the left side of the heart."
Explanation:
A patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, remains open. In PDA, blood is shunted from the aorta (left side of the heart) to the pulmonary artery (right side of the heart), resulting in increased pulmonary blood flow. Therefore, the correct statement is that "Blood is shunted to the right side of the heart."

Explanation
The Parkland formula is commonly used to calculate the fluid requirements for burn resuscitation. The formula is:
Fluid requirement (in mL)=TBSA×Weight (in kg)×Fluid volume (in mL/kg)
For burn patients, the recommended fluid volume is typically 4 mL/kg for each percent of TBSA burned.
Let's calculate the fluid requirement for the given case:
Fluid requirement=40%×22 lbs×4 mL/kg
First, convert the weight from pounds to kilograms:
Weight (in kg)= Weight (in lbs)/2.2
Weight (in kg)=22 lbs/2.2≈10 kg
Now, calculate the fluid requirement:
Fluid requirement=40% x 10 kg × 4 mL/kg
Fluid requirement=1600mL(totalfluidover24hours)
Fluid for the first 8 hours:
1600/2=800ml
Thus, the child will receive 800 mL of fluid in the first 8 hours after the burn injury.
Correct Answer is C
Explanation
A. Meningococcal polysaccharide vaccine
Explanation: Meningococcal vaccine is recommended for adolescents, particularly before starting college, as it helps protect against meningococcal disease. The conjugate form of the vaccine is usually preferred over the polysaccharide form.
B. Pneumococcal polysaccharide vaccine
Explanation: Pneumococcal vaccine is generally recommended for older adults and individuals with specific medical conditions, but it may not be part of routine immunizations for healthy adolescents.
C. Influenza vaccine
Explanation:
Influenza vaccine is recommended annually for adolescents as part of routine immunizations. It helps protect against the seasonal flu, which can cause significant illness and complications.
D. Bacille Calmette-Guerin (BCG) vaccine
Explanation: BCG vaccine is primarily used in some countries to prevent tuberculosis. It is not routinely administered in the United States as part of standard immunization schedules for adolescents.
