1. A healthcare provider in a clinic is reinforcing teaching with a client of childbearing age about recommended folic acid supplements. Which of the following defects can occur in the fetus or neonate as a result of folic acid deficiency?

• A. Iron deficiency anemia
• B. Poor bone formation
• C. Macrosomic fetus
• D. Neural tube defects

Correct answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.

2. During Leopold maneuvers on a client in labor, which technique should be used by the nurse to identify the fetal lie?

• A. Apply palms of both hands to sides of the uterus
• B. Palpate the fundus of the uterus
• C. Grasp the lower uterine segment between thumb and fingers
• D. Stand facing the client's feet with fingertips outlining cephalic prominence

Correct answer: B

Rationale: Palpating the fundus of the uterus during Leopold maneuvers is crucial to identify the fetal lie. This technique allows the nurse to determine the position of the baby's back and locate the fetal heart sounds, aiding in assessing the fetal lie. Choices A, C, and D are incorrect as they do not directly relate to identifying the fetal lie during Leopold maneuvers. Applying palms to the sides of the uterus or grasping the lower uterine segment do not provide the necessary information about the fetal lie. Standing facing the client's feet and outlining cephalic prominence is more related to assessing the fetal presentation, not the fetal lie.

3. A healthcare provider is reviewing the health record of a client who is pregnant. The provider indicated the client exhibits probable signs of pregnancy. Which of the following findings should the provider expect? (Select all that apply)

• A. Chadwick's sign
• B. Goodell's sign
• C. Ballottement
• D. All of the above

Correct answer: D

Rationale: Chadwick's sign, Goodell's sign, and ballottement are probable signs of pregnancy. Chadwick's sign refers to a bluish discoloration of the cervix and vaginal mucosa. Goodell's sign is the softening of the cervix due to increased vascularity. Ballottement is the rebound of the fetus when the cervix is tapped during a vaginal examination. Recognizing these signs is essential for healthcare providers in assessing pregnancy. Therefore, all of the above choices are correct as they are all probable signs of pregnancy. Choice D is the correct answer as it includes all the expected findings.

4. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

5. When calculating the Apgar score of a newborn at 1 minute after delivery, which of the following findings would result in a score of 6?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: C

Rationale: The Apgar score is calculated based on five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the newborn's findings at 1 minute after delivery indicate a heart rate >100/min (2 points), slow, weak cry (1 point), some flexion of extremities (1 point), grimace in response to suctioning (1 point), and body pink with blue extremities (1 point). Adding these points together results in a total Apgar score of 6, reflecting the newborn's initial assessment for their overall well-being. Choice A (4) is too low based on the given findings, while Choice B (5) is also lower than the correct score of 6. Choice D (7) is too high as it would require additional findings to reach that score.
