1. 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.

2. 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.

3. A healthcare professional is assisting with the care for a client who is experiencing a ruptured ectopic pregnancy. Which of the following findings is expected with this condition?

• A. No alteration in menses
• B. Transvaginal ultrasound indicating a fetus in the uterus
• C. Blood progesterone greater than the expected reference range
• D. Report of severe shoulder pain

Correct answer: D

Rationale: Severe shoulder pain is a common finding in clients with a ruptured ectopic pregnancy due to referred pain from diaphragmatic irritation caused by blood in the abdominal cavity. This pain is known as Kehr's sign and is often experienced in the shoulder due to irritation of the phrenic nerve. Choices A, B, and C are incorrect. A ruptured ectopic pregnancy typically presents with symptoms such as abdominal pain, vaginal bleeding, and signs of shock, rather than no alteration in menses, a fetus in the uterus, or elevated blood progesterone levels.

4. A client who is at 12 weeks of gestation is reviewing a new prescription of ferrous sulfate. Which of the following statements by the client indicates understanding of the teaching?

• A. I will take this pill with my breakfast.
• B. I will take this medication with a glass of milk.
• C. I plan to drink more orange juice while taking this pill.
• D. I plan to add more calcium-rich foods to my diet while taking this medication.

Correct answer: C

Rationale: The correct answer is C. Taking iron supplements with orange juice, which contains vitamin C, enhances the absorption of iron, making the treatment more effective. Choices A, B, and D are incorrect because taking ferrous sulfate with milk, calcium-rich foods, or breakfast may hinder iron absorption due to interactions with calcium or other substances that compete with iron absorption.

5. During ambulation to the bathroom, a postpartum client experiences a gush of dark red blood that soon stops. On data collection, a nurse finds the uterus to be firm, midline, and at the level of the umbilicus. Which of the following findings should the nurse interpret this data as being?

• A. Evidence of a possible vaginal hematoma
• B. An indication of a cervical or perineal laceration
• C. A normal postpartum discharge of lochia
• D. Abnormally excessive lochia rubra flow

Correct answer: C

Rationale: The nurse should interpret this data as a normal postpartum discharge of lochia. Lochia is the normal vaginal discharge after childbirth, and the gush of dark red blood upon ambulation is typical due to the pooling of blood in the vagina when lying down, which is then released upon standing. The firm, midline uterus at the level of the umbilicus indicates normal involution of the uterus postpartum. Therefore, this scenario is consistent with the expected postpartum physiological changes rather than complications like hematoma, lacerations, or abnormal excessive bleeding. Choices A, B, and D are incorrect because the described findings are more indicative of normal postpartum processes rather than complications such as vaginal hematoma, lacerations, or excessive bleeding.
