Nursing Elites

1. A client at 36 weeks of gestation is suspected of having placenta previa. Which of the following findings support this diagnosis?

• A. Painless red vaginal bleeding
• B. Increasing abdominal pain with a non-relaxed uterus
• C. Abdominal pain with scant red vaginal bleeding
• D. Intermittent abdominal pain following the passage of bloody mucus

Correct answer: A

Rationale: Painless red vaginal bleeding is a hallmark sign of placenta previa. In this condition, the placenta partially or completely covers the cervical opening, leading to painless, bright red bleeding due to the separation of the placenta from the uterine wall. Other types of bleeding, such as those associated with abdominal pain or mucus passage, are more indicative of conditions like placental abruption rather than placenta previa. Therefore, choices B, C, and D are incorrect as they describe findings more consistent with placental abruption rather than placenta previa.

2. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?

• A. Absence of Phosphatidylglycerol (PG)
• B. Biophysical profile score of 8
• C. Lecithin/sphingomyelin (L/S) ratio of 2:1
• D. Reactive nonstress test

Correct answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

3. When reinforcing teaching with a group of new parents about proper techniques for bottle feeding, which of the following instructions should be provided?

• A. Burp the newborn at the end of the feeding
• B. Hold the newborn close in a supine position
• C. Keep the nipple full of formula throughout the feeding
• D. Refrigerate any unused formula

Correct answer: C

Rationale: The correct technique for bottle feeding includes keeping the nipple full of formula throughout the feeding to prevent air from entering the baby's stomach. This helps reduce the risk of the baby swallowing air, which can lead to discomfort and colic. Therefore, maintaining a full nipple during feeding is essential for the baby's comfort and digestion. Option A is incorrect as burping should be done during the feeding to prevent excessive air intake. Option B is incorrect as the baby should be held semi-upright, not in a supine position, to reduce the risk of choking and ear infections. Option D is irrelevant to the feeding process and does not contribute to the baby's well-being.

4. When reinforcing teaching with new parents on bathing a newborn, a nurse observes a bluish-brown marking across the newborn's lower back. Which of the following statements should the nurse make concerning the variation?

• A. This is more commonly seen in newborns who have dark skin.
• B. This is a finding indicating hyperbilirubinemia.
• C. This is a forceps mark from an operative delivery.
• D. This is related to prolonged birth or trauma during delivery.

Correct answer: A

Rationale: A bluish-brown marking across the lower back is more commonly seen in newborns with dark skin. These markings are known as Mongolian spots and are benign. They are not related to hyperbilirubinemia, forceps marks, or trauma during delivery. Choice B is incorrect because hyperbilirubinemia presents as jaundice, not as a bluish-brown marking. Choice C is incorrect because forceps marks would have a different appearance and location. Choice D is incorrect as Mongolian spots are not related to prolonged birth or trauma during delivery.

5. 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.
