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 at 39 weeks of gestation in a prenatal clinic asks about signs preceding labor. Which of the following should the nurse identify as a sign that precedes labor?

• A. Decreased vaginal discharge
• B. A surge of energy
• C. Urinary retention
• D. Weight gain of 0.5 to 1.5 kg

Correct answer: B

Rationale: A surge of energy is a common sign that precedes labor. This burst of energy, often referred to as the 'nesting instinct,' is believed to occur as the body prepares for labor, prompting the individual to undertake tasks to prepare for the arrival of the baby. Decreased vaginal discharge is not a typical sign preceding labor. Urinary retention is not a sign that precedes labor and may indicate another issue. Weight gain of 0.5 to 1.5 kg is not a specific sign of impending labor.

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. A woman in a women's health clinic is receiving teaching about nutritional intake during her 8th week of gestation. The healthcare provider should advise the woman to increase her daily intake of which of the following nutrients?

• A. Calcium
• B. Vitamin E
• C. Iron
• D. Vitamin D

Correct answer: C

Rationale: During pregnancy, the recommended daily iron intake is higher compared to non-pregnant women. Pregnant women should aim for 27 mg/day of iron, while non-pregnant women require 15 mg/day if under 19 years old and 18 mg/day if between 19 and 50 years old. Iron is essential during pregnancy to support the increased blood volume and ensure the proper oxygen supply to the fetus. Calcium is important for bone health but does not need a significant increase during early pregnancy. Vitamin E and Vitamin D are important but do not have specific increases recommended during the 8th week of gestation.

5. A newborn is small for gestational age (SGA). Which of the following findings is associated with this condition?

• A. Moist skin
• B. Protruding abdomen
• C. Gray umbilical cord
• D. Wide skull sutures

Correct answer: D

Rationale: Wide skull sutures are a common finding in newborns who are small for gestational age (SGA) due to reduced intrauterine growth. This occurs because the skull bones do not grow at the same rate as the brain, leading to wider sutures. Moist skin, a protruding abdomen, and a gray umbilical cord are not typically associated with being small for gestational age.
