Maternity HESI Quizlet

Correct Answer: A

Rationale: The correct answer is A: Prevent eye infection. Eye ointment, usually containing erythromycin, is applied to prevent neonatal conjunctivitis, which can be caused by bacteria present in the birth canal. It is not used to dilate the pupil, clear the infant's vision, or prevent herpes infection.

Correct Answer: B

Rationale: The correct answer is B: Screen for neural tube defects. Alpha fetoprotein testing is primarily used to screen for neural tube defects and other fetal abnormalities. It is not used to detect cardiovascular disorders, monitor placental functioning, or assess for maternal pre-eclampsia.

Correct Answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.

Correct Answer: A

Rationale: Flaring of the nares is a classic sign of respiratory distress in newborns. It indicates that the newborn is working hard to breathe, and immediate attention should be given to assess and address the respiratory status of the infant.

Correct Answer: D

Rationale: When examining an infant for cryptorchidism, it is important to position the infant in a warm room to prevent muscle contraction, which could cause the testes to retract. Placing the infant in a side-lying position may not be necessary for this specific examination. Holding the penis or retracting the foreskin is not relevant to the assessment for cryptorchidism. Cleansing the penis with an antiseptic pad is not indicated for this examination.
