Correct Answer: A

Rationale: The nurse should educate clients that inadequate folic acid intake is associated with an increased risk of neural tube defects in newborns. Consuming an adequate amount of folic acid from sources like fortified cereals, oranges, artichokes, liver, broccoli, and asparagus can help prevent this serious fetal abnormality. Trisomy 21 (Choice B) is caused by an extra chromosome 21 and is not preventable by folic acid intake. Cleft lip (Choice C) and atrial septal defect (Choice D) are not directly linked to folic acid intake during pregnancy.

Correct Answer: D

Rationale: The correct answer is D, respiratory distress, as it is a clinical manifestation of hypoglycemia in newborns. Other signs of hypoglycemia include an abnormal cry, jitteriness, lethargy, poor feeding, apnea, and seizures. Hypertonia, increased feeding, and hyperthermia are not typically associated with hypoglycemia in newborns. Hypertonia is more indicative of neurological issues, increased feeding is not a common sign of hypoglycemia, and hyperthermia is not a typical symptom of low blood sugar.

Correct Answer: C

Rationale: The nurse should assist the client into the hands and knees position during contractions to help relieve her back pain and facilitate the rotation of the fetus from the posterior to an anterior occiput position. This position can aid in optimal fetal positioning for delivery. Choice A, performing effleurage, is a massage technique that may provide comfort but does not address the fetal position. Placing the client in lithotomy position (Choice B) may not be ideal for a client experiencing back pain due to the occiput posterior position. Applying a scalp electrode to the fetus (Choice D) is not indicated solely for addressing the client's back pain.

Correct Answer: A

Rationale: In hyperemesis gravidarum, where there is severe nausea and vomiting during pregnancy, it is essential for the client to eat foods that appeal to their taste to prevent further nausea. Balancing meals may not be a priority initially if the client is struggling to keep any food down. Choice B is unrelated to managing hyperemesis gravidarum. Choice C, having hot tea with each meal, may not necessarily address the issue of taste preferences. Choice D, pairing sweets with a starch, is not as relevant as choosing foods appealing to taste for managing hyperemesis gravidarum.

Correct Answer: B

Rationale: A newborn's respiratory rate can vary between 20 to 100 breaths per minute during the initial phase after birth. A respiratory rate as low as 18 breaths per minute at this early stage requires immediate nursing intervention. This finding necessitates further assessment to ensure adequate oxygenation and respiratory function. The other options, heart rate of 168/min, tremors, and fine crackles, are within normal limits for a full-term newborn and do not require immediate intervention.
