Correct Answer: B

Rationale: In cases of inevitable abortion, offering the option to view products of conception can assist in emotional healing and closure for the client. This can provide a sense of acknowledgment and closure for the loss experienced, aiding in the grieving process. Administering oxygen via nasal cannula (choice A) is not directly related to the emotional and psychological support needed during an inevitable abortion. Instructing the client to increase potassium-rich foods (choice C) may not be a priority in this situation. Maintaining the client on bed rest (choice D) may be indicated in some cases but does not address the emotional aspect of the situation.

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: D

Rationale: The correct answer is D. In a persistent occiput posterior position, the baby's head presses against the mother's spine, causing prolonged labor and severe backache. This position can lead to difficulties in labor progress and increase discomfort for the mother. Choices A, B, and C are incorrect as they do not directly relate to the client's difficult, prolonged labor with severe backache. Fetal attitude, fetal lie, and maternal pelvis type may affect labor, but in this scenario, the persistent occiput posterior fetal position is the primary contributing cause for the client's symptoms.

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: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.
