Nursing Elites

1. In developing a teaching plan for expectant parents, the nurse plans to include information about when the parents can expect the infant's fontanels to close. The LPN/LVN bases the explanation on knowledge that for the normal newborn, the

• A. anterior fontanel closes at 2 to 4 months and the posterior by the end of the first week.
• B. anterior fontanel closes at 5 to 7 months and the posterior by the end of the second week.
• C. anterior fontanel closes at 8 to 11 months and the posterior by the end of the first month.
• D. anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month.

Correct answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.

2. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

3. A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. What should the nurse do first?

• A. Suction the oral and nasal passages.
• B. Give oxygen by positive pressure.
• C. Stimulate the infant to cry.
• D. Turn the infant onto the right side.

Correct answer: A

Rationale: In a situation where an infant regurgitates and turns cyanotic, the priority action should be to clear any potential airway obstruction. Suctioning the oral and nasal passages is crucial to ensure the infant's airway is clear and allow for proper breathing. This intervention takes precedence over providing oxygen, stimulating the infant to cry, or repositioning the infant.

4. A new mother is having trouble breastfeeding her newborn son. He is making frantic rooting motions and will not grasp the nipple. What intervention would be most helpful to this mother?

• A. Ask the mother to stop feeding, comfort the infant, and then assist the mother to help the baby latch on.
• B. Use a nipple shield to help the baby latch on.
• C. Try a different breastfeeding position.
• D. Have another person help the mother with breastfeeding.

Correct answer: A

Rationale: In this scenario, the best intervention is to ask the mother to stop feeding, comfort the infant, and then assist her in helping the baby latch on. Stopping the feeding and providing comfort can reduce the infant's frustration and create a calmer environment for successful breastfeeding. Choice B, using a nipple shield, may not address the underlying issue causing the baby's difficulty latching. Choice C, trying a different breastfeeding position, can be attempted after the baby is calm and ready to latch. Choice D, having another person help, may not be necessary if the mother can be guided effectively on latching techniques.

5. A client addicted to heroin and newly pregnant asks a nurse about ensuring her baby's health while on methadone. What should the nurse advise?

• A. Sign up for group therapy sessions.
• B. Discontinue the methadone right away.
• C. Start prenatal care as soon as possible.
• D. Describe genetic testing protocol.

Correct answer: C

Rationale: Initiating prenatal care promptly is essential for monitoring the well-being of both the mother and the fetus, particularly in high-risk pregnancies involving substance use. Early prenatal care allows for timely interventions, education, and support to promote a healthier pregnancy and birth outcomes. Choice A is incorrect because while group therapy may be beneficial, initiating prenatal care is more crucial at this stage. Choice B is incorrect as abrupt discontinuation of methadone can be harmful and should be managed under medical supervision. Choice D is incorrect as genetic testing is not the immediate priority in this scenario.
