HESI Maternity 55 Questions Quizlet
1. The healthcare provider prescribes oxytocin 2 milliunits/minute to induce labor for a client at 41-weeks gestation. The nurse initiates an infusion of Ringer’s Lactate solution 1000 mL with oxytocin 10 units. How many mL/hour should the nurse program the infusion pump?
- A. 12 mL/hour
- B. 2 mL/hour
- C. 22 mL/hour
- D. 42 mL/hour
Correct answer: A
Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) × total volume (1000 mL) ÷ units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.
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 new mother who is breastfeeding her 4-week-old infant and has type 1 diabetes reports that her insulin needs have decreased since the birth of her child. Which action should the nurse implement?
- A. Inform her that a decreased need for insulin occurs while breastfeeding.
- B. Counsel her to increase her caloric intake.
- C. Advise the client to breastfeed more frequently.
- D. Schedule an appointment for the client with the diabetic nurse educator.
Correct answer: A
Rationale: The correct answer is A. During breastfeeding, insulin needs often decrease due to the metabolic demands of milk production. Therefore, the nurse should inform the client that this decrease in insulin requirements is a normal response to breastfeeding. Choice B is incorrect as increasing caloric intake is not directly related to the decrease in insulin needs during breastfeeding. Choice C is incorrect as advising the client to breastfeed more frequently does not address the issue of decreased insulin needs. Choice D is incorrect as scheduling an appointment with the diabetic nurse educator is not necessary at this point since the decreased need for insulin is a common physiological response to breastfeeding.
4. During a non-stress test (NST) at 41-weeks gestation, the LPN/LVN notes that the client is not experiencing contractions, the fetal heart rate (FHR) baseline is 144 bpm, and no FHR accelerations are present. What action should the nurse take?
- A. Check the client for urinary bladder distention.
- B. Notify the healthcare provider of the nonreactive results.
- C. Have the mother stimulate the fetus to move.
- D. Ask the client if she has felt any fetal movement.
Correct answer: D
Rationale: In this scenario, the nurse should ask the client if she has felt any fetal movement. This action is important as assessing for fetal movement can help determine if the absence of FHR accelerations is attributed to fetal sleep or decreased fetal activity. It is crucial to gather information directly from the client to aid in the assessment and decision-making process. This approach can provide valuable insights into the fetal well-being and guide further interventions if needed.
5. The healthcare provider is providing preconception counseling. Which supplement should the provider recommend to help prevent the occurrence of anencephaly?
- A. Folic Acid.
- B. Calcium.
- C. Iron.
- D. Vitamin D.
Correct answer: A
Rationale: Folic acid supplementation before and during early pregnancy is crucial for reducing the risk of neural tube defects, including anencephaly. Anencephaly is a severe birth defect in which a baby is born without parts of the brain and skull. Folic acid plays a key role in neural tube development and can significantly lower the chances of such defects when taken prior to conception and in early pregnancy.
