Nursing Elites

1. A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?

• A. 45
• B. 15 mL
• C. 4
• D. 13

Correct answer: D

Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 × X = 0.25 × 1000. X = (0.25 × 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.

2. Just after delivery, a new mother tells the nurse, 'I was unsuccessful breastfeeding my first child, but I would like to try with this baby.' Which intervention is best for the LPN/LVN to implement first?

• A. Assess the husband's feelings about his wife's decision to breastfeed their baby.
• B. Ask the client to describe why she was unsuccessful with breastfeeding her last child.
• C. Encourage the client to develop a positive attitude about breastfeeding to help ensure success.
• D. Provide assistance to the mother to begin breastfeeding as soon as possible after delivery.

Correct answer: D

Rationale: The correct intervention is to provide immediate assistance to the mother to begin breastfeeding as soon as possible after delivery. This approach helps initiate bonding and successful breastfeeding. Taking action promptly can address the mother's desire to breastfeed and promote positive outcomes for both the mother and the newborn.

3. When counseling a couple seeking information about conceiving, the LPN/LVN should know that ovulation usually occurs

• A. two weeks before menstruation.
• B. immediately after menstruation.
• C. immediately before menstruation.
• D. three weeks before menstruation.

Correct answer: A

Rationale: Ovulation typically occurs about 14 days before the start of the next menstrual period. This timing allows for the released egg to travel down the fallopian tube where it may be fertilized by sperm, leading to conception. Understanding the timing of ovulation is crucial for couples trying to conceive to increase their chances of success.

4. After a client delivered vaginally 2 days ago, what information should you share with her if she wants to resume using her diaphragm for birth control?

• A. The diaphragm is the most effective form of contraception.
• B. The diaphragm must be refitted after childbirth.
• C. Vaseline lubricant should be used when inserting the diaphragm.
• D. The diaphragm should be inserted 2 to 4 hours before intercourse.

Correct answer: B

Rationale: After childbirth, the diaphragm must be refitted to ensure a proper fit and effectiveness. Changes in the body post-delivery can affect the fit of the diaphragm, making it necessary to get refitted. Choice A is incorrect because while the diaphragm can be effective, it is not the most effective form of contraception. Choice C is incorrect because oil-based lubricants like Vaseline can damage latex diaphragms. Choice D is incorrect because the diaphragm should be inserted no more than 2 hours before intercourse, not 2 to 4 hours.

5. 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.
