Correct Answer: C

Rationale: The nurse should interpret this data as a normal postpartum discharge of lochia. Lochia is the normal vaginal discharge after childbirth, and the gush of dark red blood upon ambulation is typical due to the pooling of blood in the vagina when lying down, which is then released upon standing. The firm, midline uterus at the level of the umbilicus indicates normal involution of the uterus postpartum. Therefore, this scenario is consistent with the expected postpartum physiological changes rather than complications like hematoma, lacerations, or abnormal excessive bleeding. Choices A, B, and D are incorrect because the described findings are more indicative of normal postpartum processes rather than complications such as vaginal hematoma, lacerations, or excessive bleeding.

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: C

Rationale: The correct answer is C because cleaning the penis with each diaper change is essential for preventing infection and promoting healing after circumcision. This practice helps maintain good hygiene and reduces the risk of complications. Removing the yellow mucus or giving a tub bath too soon can interfere with the healing process and increase the likelihood of infection. Choice A is incorrect because circumcision healing usually takes about a week or more, not just a couple of days. Choice B is incorrect because parents should gently clean the area, including removing any discharge or debris as part of proper care. Choice D is incorrect because tub baths should be avoided until the circumcision is fully healed to prevent infection.

Correct Answer: A

Rationale: The correct treatment for chlamydia is a one-time dose of azithromycin. It is crucial for the client to understand the correct medication regimen for effective treatment. Choice B is incorrect because treatment is necessary for the partner even if asymptomatic. Choice C is incorrect because sexual relations should be avoided until treatment is completed. Choice D is incorrect as retesting should generally occur 3 months after treatment.

Correct Answer: D

Rationale: Covering the newborn's head with a cap is the highest priority immediately following birth to prevent heat loss. Newborns are at risk of hypothermia due to their immature thermoregulation, making it crucial to maintain their body temperature. By covering the newborn's head with a cap, heat loss through the head is minimized, helping to keep the baby warm and stable in the immediate post-birth period. Initiating breastfeeding, performing the initial bath, and giving a vitamin K injection are important interventions but are not as high a priority as ensuring the newborn's thermal stability.
