Correct Answer: A

Rationale: Individuals with phenylketonuria (PKU) have difficulty breaking down phenylalanine, an amino acid found in protein-rich foods like peanut butter. Therefore, clients with PKU should avoid foods high in phenylalanine, such as peanut butter, to prevent adverse effects on their health. Choices B, C, and D are not typically high in phenylalanine and do not pose the same risk to individuals with PKU as peanut butter.

Correct Answer: B

Rationale: The correct answer is B because the client needs a second varicella vaccination at the postpartum visit to ensure immunity. Option A is incorrect as it implies a future need for a second vaccination without a clear action plan. Option C is incorrect as the varicella vaccine is primarily for the client's protection, not others. Option D is not the appropriate action as waiting to be tested for immunity delays the necessary second vaccination.

Correct Answer: C

Rationale: Tilting the bottle to prevent air from entering as the baby sucks can lead to the baby swallowing air, causing discomfort and potential issues like colic or gas. The correct way to bottle-feed a newborn is by ensuring that the nipple is always filled with milk to avoid air intake, which can lead to problems. Keeping the baby's head elevated while feeding helps prevent choking, allowing the baby to burp several times during each feeding helps release swallowed air, and soft, formed yellow stools indicate a healthy digestion process in newborns.

Correct Answer: B

Rationale: The correct answer is B: Rooting. The rooting reflex is crucial in newborns as it helps them locate the nipple for feeding. This reflex involves turning the head towards a stimulus that touches the cheek or mouth, aiding in the process of latching onto the breast for breastfeeding. The Babinski reflex is the fanning out and curling of the toes when the sole of the foot is stroked, the Moro reflex is the startle reflex in response to a sudden noise or movement, and the stepping reflex is the appearance of taking steps when an infant is held upright with feet touching a solid surface. Therefore, choices A, C, and D are incorrect as they do not play a direct role in promoting a newborn to latch during breastfeeding.

Correct Answer: D

Rationale: The correct action to check for the Moro reflex in a newborn is to hold the newborn in a semi-sitting position and then allow the newborn's head and trunk to fall backward. The Moro reflex is elicited by a sudden loss of support or a loud noise. The normal response involves symmetrical abduction and extension of the arms, followed by their return to the midline in an embracing motion. Choices A, B, and C do not describe the correct method for assessing the Moro reflex and are therefore incorrect.
