1. During the third trimester of pregnancy, which of the following findings should a nurse recognize as an expected physiologic change?
- A. Gradual lordosis
- B. Increased abdominal muscle tone
- C. Posterior neck flexion
- D. Decreased mobility of pelvic joints
Correct answer: A
Rationale: During pregnancy, gradual lordosis is a common adaptation to the growing fetus. Lordosis refers to an increased lumbar curve in the spine, which helps to shift the center of gravity forward, supporting the enlarging uterus. This change is necessary to maintain balance and reduce strain on the back muscles as the pregnancy progresses. Increased abdominal muscle tone, posterior neck flexion, and decreased mobility of pelvic joints are not typical physiological changes during pregnancy. Increased abdominal muscle tone is not expected as the abdominal muscles tend to stretch and separate to accommodate the growing fetus. Posterior neck flexion is not a common finding and decreased mobility of pelvic joints is not an expected change and can cause discomfort.
2. A client has severe preeclampsia and is receiving magnesium sulfate IV. Which of the following findings should the nurse identify and report as signs of magnesium sulfate toxicity? (Select all that apply)
- A. Respirations less than 12/min
- B. Urinary output less than 25 mL/hr
- C. Decreased level of consciousness
- D. All of the above
Correct answer: D
Rationale: Signs of magnesium sulfate toxicity include respirations less than 12/min, urinary output less than 25 mL/hr, and decreased level of consciousness. These signs indicate potential overdose of magnesium sulfate and require immediate attention to prevent further complications. Reporting these signs promptly is crucial to ensure the client's safety and well-being. Choice D, 'All of the above,' is the correct answer as all the listed findings are indicative of magnesium sulfate toxicity. Choices A, B, and C individually represent different signs of toxicity, making them incorrect on their own. Therefore, the nurse should be vigilant in identifying and reporting all these signs to prevent adverse outcomes.
3. A healthcare professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 60
- B. 30
- C. 50
- D. 80
Correct answer: C
Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.
4. While caring for a newborn undergoing phototherapy to treat hyperbilirubinemia, which of the following actions should the nurse take?
- A. Cover the newborn's eyes with an opaque eye mask while under the phototherapy light.
- B. Keep the newborn in a shirt while under the phototherapy light.
- C. Apply a light moisturizing lotion to the newborn's skin.
- D. Turn and reposition the newborn every 4 hours while undergoing phototherapy.
Correct answer: A
Rationale: It is crucial to cover the newborn's eyes with an opaque eye mask to prevent damage to the retinas and corneas from the phototherapy light. The eyes are particularly sensitive to the light used in phototherapy, and shielding them helps protect the newborn's delicate eyes from potential harm. Choice B is incorrect because the newborn should be undressed to maximize skin exposure to the phototherapy light. Choice C is incorrect because lotions or oils can interfere with the effectiveness of phototherapy. Choice D is incorrect because the newborn should be kept as still as possible to maximize exposure to the light.
5. A nurse is teaching clients in a prenatal class about the importance of taking folic acid during pregnancy. The nurse should instruct the clients to consume an adequate amount of folic acid from various sources to prevent which of the following fetal abnormalities?
- A. Neural tube defect
- B. Trisomy 21
- C. Cleft lip
- D. Atrial septal defect
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.
