1. 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.
2. What action should be implemented when preparing to measure the fundal height of a pregnant client?
- A. Have the client empty her bladder.
- B. Request the client lie on her left side.
- C. Perform Leopold's maneuvers first.
- D. Give the client some cold juice to drink.
Correct answer: A
Rationale: The correct action when preparing to measure the fundal height of a pregnant client is to have the client empty her bladder. This is essential to ensure an accurate measurement because a full bladder can displace the uterus and affect the accuracy of the assessment. Choice B is incorrect because the client should lie flat on her back, not on her left side, to measure fundal height accurately. Choice C is incorrect because Leopold's maneuvers are used to determine the position of the fetus, not to measure fundal height. Choice D is incorrect as giving the client cold juice is not necessary for measuring fundal height.
3. A 3-month-old with myelomeningocele and atonic bladder is catheterized every 4hrs to prevent urinary retention. The home health nurse notes that the child has developed episodes of sneezing, urticarial, watery eyes, and a rash in the diaper area. What action is most important for the nurse to take?
- A. Auscultate the lungs for respiratory pneumonia.
- B. Change to latex-free gloves when handling infant.
- C. Draw blood to analyze for streptococcal infection.
- D. Apply zinc oxide to perineum with each diaper change.
Correct answer: B
Rationale: Latex allergy is a concern in patients with myelomeningocele, so switching to latex-free gloves is important.
4. The healthcare provider notes on the fetal monitor that a laboring client has a variable deceleration. Which action should the healthcare provider implement first?
- A. Assess cervical dilation.
- B. Change the client's position.
- C. Administer oxygen via facemask.
- D. Turn off the oxytocin infusion.
Correct answer: B
Rationale: Changing the client's position is the priority intervention for variable decelerations as it can relieve pressure on the umbilical cord, potentially resolving the deceleration and improving fetal oxygenation. Assessing cervical dilation, administering oxygen via facemask, and turning off the oxytocin infusion are important interventions but addressing the fetal distress caused by variable decelerations takes precedence.
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.
