Correct Answer: A

Rationale: The correct answer is A: Perform a sharp hand clap near the infant. The Moro reflex, also known as the startle reflex, is elicited by a sudden stimuli such as a sharp hand clap near the infant. This reflex is characterized by the infant's arms extending and then flexing with a distinctive 'startle' motion. It is a normal and expected reflex in newborns, typically disappearing by 3-6 months of age. Choices B, C, and D are incorrect because they do not elicit the Moro reflex; holding the newborn vertically (choice B) or placing a finger at the base of the newborn's toes (choice C) are associated with other reflexes, while turning the newborn's head quickly to one side (choice D) is related to the tonic neck reflex.

Correct Answer: C

Rationale: Plantar creases covering 2/3 of the sole is an important physical characteristic used to assess gestational age in a newborn. This finding is significant because as gestational age advances, the plantar creases cover a larger portion of the sole. It is a valuable clue to the healthcare provider in determining the newborn's maturity level. Choices A, B, and D are incorrect as they do not specifically relate to gestational age assessment. Acrocyanosis and vernix caseosa are common findings in newborns but are not directly used for determining gestational age. The softness and level of the anterior fontanel can provide information about intracranial pressure but are not directly related to gestational age assessment.

Correct Answer: B

Rationale: Kegel exercises are beneficial during pregnancy to help strengthen pelvic muscles, which is crucial for childbirth. Pelvic muscle stretching during birth is a key aspect of labor, making choice B the correct statement indicating understanding of the teaching. Choices A, C, and D are incorrect because Kegel exercises primarily focus on strengthening pelvic floor muscles to support the uterus, bladder, and bowel, aiding in labor and delivery. They are not directly related to preventing constipation, decreasing backaches, or preventing stretch marks.

Correct Answer: D

Rationale: The correct answer is D. Ambulating twice daily is not recommended for a client with severe preeclampsia. Clients with severe preeclampsia are at risk for seizures and should be on bed rest to prevent complications. Ambulation can increase blood pressure and the risk of seizure activity in these clients. Assessing deep tendon reflexes, obtaining a daily weight, and continuous fetal monitoring are all appropriate and important interventions for a client with severe preeclampsia to monitor for signs of worsening condition and fetal well-being.

Correct Answer: A

Rationale: Assessing the firmness of the uterus is crucial in this situation. A uterus that is not firm could indicate postpartum hemorrhage, a common cause of low blood pressure after childbirth. By evaluating the firmness of the uterus, the nurse can quickly identify and address potential complications, such as excessive bleeding. Initiating oxygen therapy, administering oxytocin infusion, or obtaining a type and crossmatch may be necessary interventions later, but assessing the firmness of the uterus takes precedence as the first step in managing postpartum complications.
