Correct Answer: C

Rationale: Newborn hiccups are common and usually harmless. They are typically caused by the baby's immature diaphragm and tend to resolve on their own. It is essential for parents to understand that hiccups in newborns are a normal phenomenon and do not necessarily indicate any underlying health issue. Choice A is incorrect because hiccups are not a sign of respiratory distress in newborns. Choice B is incorrect as hiccups do not indicate the baby is overeating. Choice D is also incorrect as hiccups are not solely caused by a lack of burping.

Correct Answer: A

Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.

Correct Answer: A

Rationale: When the top of the ear (pinna) is parallel to the outer and inner canthus of the eye, it is considered a normal position in a newborn. This alignment is an important assessment to ensure normal development and anatomy. Choices B, C, and D are incorrect because the parallel alignment of the ears to the outer and inner canthus of the eye is not indicative of a possible chromosomal abnormality, facial paralysis, or prematurity. It is simply a normal anatomical finding in a newborn.

Correct Answer: D

Rationale: A saturated perineal pad in 15 minutes indicates excessive bleeding, known as postpartum hemorrhage, which is a critical condition requiring immediate intervention to prevent further complications like hypovolemic shock. Monitoring and managing postpartum bleeding are crucial in the early postpartum period to ensure the client's safety and well-being. The other options are normal postpartum findings: lochia rubra with a few small clots is expected in the early postpartum period, a firm and midline fundus indicates proper uterine contraction, and a temperature of 100.4°F (38°C) is within the normal range for the postpartum period.

Correct Answer: C

Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.
