The nurse knows which congenital cardiac defect is characterized by a mixing of well-oxygenated blood with poorly oxygenated blood.

Hypoplastic heart syndrome

Atrioventricular canal defect

Tetralogy of Fallot

Coarctation of the aorta

Answer and Explanation

The Correct Answer is B

A. Hypoplastic heart syndrome: Characterized by underdevelopment of the left side of the heart, not mixing of blood.
B. Atrioventricular canal defect: An atrioventricular canal defect allows oxygenated and deoxygenated blood to mix due to the presence of a common atrioventricular valve and defects in the atrial and ventricular septa. This defect results in a mixture of oxygenated and deoxygenated blood, which can cause varying levels of oxygenation in the blood delivered to the body.
C. Tetralogy of Fallot: Involves a ventricular septal defect leading to right-to-left shunting, but not a direct mixing of oxygenated and deoxygenated blood.
D. Coarctation of the aorta: Involves narrowing of the aorta, not mixing of oxygenated and deoxygenated blood.

Explanation

1st Trimester (Conception-13 weeks)

Fetus has a heartbeat: The fetal heartbeat can typically be detected around 6 weeks gestation using ultrasound, marking the beginning of cardiac development in the first trimester.

2nd Trimester (14-26 weeks)

Gender can be determined: Gender determination through ultrasound is generally possible around the 18-20 week mark in the second trimester when fetal genitalia are more distinguishable.

3rd Trimester (27-40 weeks)

Surfactant production: Surfactant production by the fetal lungs begins in the third trimester, usually around 24-28 weeks, but continues to increase throughout the remainder of pregnancy.
Sucking occurs: Fetal sucking movements start to develop around the 28th week and become more coordinated as the third trimester progresses.
Fetal respiratory movements begin: Fetal respiratory movements, where the fetus practices breathing by moving the diaphragm, begin in the third trimester to prepare for life outside the womb.
Increase in body fat: The fetus begins to accumulate more body fat in the third trimester, which helps with thermoregulation and provides energy reserves for birth and early postnatal life.

A. Call the child abuse hotline B. Educate the mother on safety C. Inform the mother to call the nurse for all diaper changes D. Complete the Morse Fall Scale

Correct Answer is A

Explanation

A. Call the child abuse hotline. A spiral fracture, especially in a non-ambulatory infant, is highly suspicious for non-accidental trauma (child abuse). Reporting suspected abuse is mandatory to protect the child from further harm.
B. Educate the mother on safety. While important for prevention, addressing potential abuse takes precedence.
C. Inform the mother to call the nurse for all diaper changes. This does not address the immediate concern of suspected child abuse.
D. Complete the Morse Fall Scale. This is irrelevant in the context of suspected child abuse.
