Rationale: The Apgar score assesses a newborn's physical condition immediately after birth by evaluating heart rate, respiratory effort, muscle tone, reflex response, and color. Therefore, the correct answer is A. The other choices are incorrect because B) the Apgar score does not predict future intelligence, C) it does not measure parent and newborn interaction, and D) it is not used to determine gestational age.

Rationale: The Hib conjugate vaccine is crucial for protecting children from several severe infections caused by Haemophilus influenzae type b, including bacterial meningitis, epiglottitis, bacterial pneumonia, septic arthritis, and sepsis. Therefore, all the provided options are correct. Bacterial meningitis, epiglottitis, and bacterial pneumonia are serious conditions that the Hib vaccine effectively prevents, making choice D the correct answer. Choices A, B, and C are incorrect when considered individually as the Hib vaccine does not protect against only one specific infection; rather, it provides immunity against multiple diseases caused by Haemophilus influenzae type b.

Correct Answer: C

Rationale: When a parent's infant is born with physical defects, understanding the psychological reactions is crucial. The reaction is often similar to the grief experienced when facing the death of a child. Parents need to grieve for the loss of the expected child and adapt to the needs of a child with physical defects. The grief process typically involves stages like shock, frustration, and anger, which can last for years. Denial during the shock phase is not maladaptive but can help parents cope initially. Additionally, parents are sensitive to the behavior of health professionals, whose interactions can significantly influence the parents' reactions to the infant. Therefore, recognizing the similarity of the psychological reaction to grief is an important consideration in understanding how parents cope with their infant's physical defects.

Correct Answer: D

Rationale: Acetaminophen (Tylenol) is recommended to help relieve the discomfort associated with acute otitis media, such as pain and fever. Elevating the baby's head during sleep can also help with drainage and relieve pressure, making choice A incorrect. Administering an antibiotic may be necessary for bacterial otitis media but is not usually the first-line treatment for acute otitis media, so choice B is incorrect. Placing the baby to sleep with a bottle can increase the risk of ear infections due to the pooling of milk around the Eustachian tube, so choice C is incorrect.

Correct Answer: D

Rationale: The correct answer is D because babbling is an early indicator of hearing ability in infants. Lack of babbling by 2 months may suggest a potential hearing issue. Choices A, B, and C are incorrect because turning away from a sound, startling with sudden loud noises immediately after birth, and talking at 4 months are not primary indicators of hearing loss in infants.
