How should the nurse respond to a parent who asks, "How can I protect my baby from whooping cough?"
"Make sure your child gets the pertussis vaccine."
"Don't worry; your baby will have maternal immunity to pertussis that will last until approximately 18 months old."
"Have the family doctor prescribe prophylactic antibiotics for all close contacts."
"Have your pediatrician prescribe erythromycin."
"See the doctor when the baby gets a respiratory infection."
The Correct Answer is A
A. Vaccination is the primary prevention for pertussis (whooping cough). Infants receive the DTaP series starting at 2 months of age, which provides protection against the disease. Ensuring timely immunizations is the most effective method to protect the baby.
B. Maternal immunity is partial and short-lived, typically waning within the first few months of life. It does not provide protection until 18 months, so relying on maternal antibodies alone is inadequate.
C. Prophylactic antibiotics for contacts are recommended only in specific exposure situations, not as routine protection. Vaccination remains the main preventive measure.
D. Prescribing erythromycin is used for treatment or post-exposure prophylaxis in certain cases but is not a primary preventive strategy for all infants.
E. Waiting until the baby develops symptoms does not prevent infection and may result in severe illness, especially since infants are at high risk for complications from pertussis.

Correct Answer is C
Explanation
A. Two veins and one artery is an abnormal configuration. This pattern is not consistent with normal fetal circulation and may indicate a congenital anomaly.
B. One artery and one vein (single umbilical artery) is a known variation, but it is considered abnormal and can be associated with renal, cardiac, or chromosomal anomalies.
C. The normal umbilical cord contains two arteries and one vein. The umbilical vein carries oxygenated, nutrient-rich blood from the placenta to the fetus, supporting growth and development. The two umbilical arteries carry deoxygenated blood and waste products from the fetus back to the placenta for elimination. This arrangement ensures efficient bidirectional circulation between the fetus and placenta. Inspecting the cord after birth helps the nurse identify abnormalities that may require further evaluation.
D. Two arteries and two veins is not a typical configuration and may suggest a congenital anomaly or cord malformation.
Correct Answer is A
Explanation
A.This is correct because cleansing the abdomen reduces the risk of infection at the puncture site and is standard pre-procedure preparation for amniocentesis.
B. This is incorrect at 23 weeks gestation because a partially full bladder is preferred. A partially full bladder helps elevate the uterus, providing better access for the needle and reducing the risk of injury to the fetus.
C. This is incorrect because fasting is not necessary for amniocentesis. Clients may eat and drink normally unless sedation or other procedures requiring anesthesia are planned. Restricting food and fluids is unnecessary and could cause discomfort.
D. This is incorrect because bowel preparation is not required. The procedure involves the uterus and amniotic sac, not the gastrointestinal tract, so a bowel prep would not affect safety or outcomes.
