HESI Maternity 55 Questions Quizlet
1. A postpartum client who is Rh-negative refuses to receive RhoGAM after the delivery of an infant who is Rh-positive. Which information should the nurse provide this client?
- A. RhoGAM prevents maternal antibody formation for future Rh-positive babies.
- B. RhoGAM is not necessary unless all of her pregnancies are Rh-positive.
- C. The Rh-positive factor from the fetus threatens her blood cells.
- D. The mother should receive RhoGAM when the baby is Rh-negative.
Correct answer: A
Rationale: The correct answer is A. RhoGAM is administered to Rh-negative individuals after exposure to Rh-positive blood to prevent the development of antibodies that could harm future Rh-positive babies during subsequent pregnancies. By refusing RhoGAM after the delivery of an Rh-positive infant, the mother risks developing these antibodies, which could lead to hemolytic disease in future pregnancies with Rh-positive babies. Therefore, it is crucial for the nurse to explain to the client that receiving RhoGAM prevents the formation of maternal antibodies against Rh-positive blood, safeguarding the health of future babies. Choices B, C, and D are incorrect. Choice B is incorrect because RhoGAM is necessary after exposure to Rh-positive blood, regardless of the Rh status of future pregnancies. Choice C is incorrect as it does not accurately convey the purpose of RhoGAM administration. Choice D is incorrect because RhoGAM is specifically given after exposure to Rh-positive blood, not when the baby is Rh-negative.
2. At 40-weeks gestation, a client presents to the obstetrical floor indicating that the amniotic membranes ruptured spontaneously at home. She is in active labor and feels the need to bear down and push. Which information is most important for the nurse to obtain?
- A. Color and consistency of fluid.
- B. Estimated amount of fluid.
- C. Any odor noted when membranes ruptured.
- D. Time the membranes ruptured.
Correct answer: A
Rationale: The color and consistency of the amniotic fluid are crucial to assess for the presence of meconium, which may indicate fetal distress. Meconium-stained amniotic fluid can suggest fetal compromise and the need for further evaluation and monitoring. The estimated amount of fluid is less critical than assessing for meconium. While noting any odor when the membranes ruptured may provide some information, it is not as crucial as assessing for meconium. The time the membranes ruptured is important for documenting the timeline but does not directly impact immediate patient care like assessing for fetal distress.
3. 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.
4. The nurse is caring for a client who experienced fetal demise at 32 weeks' gestation. After the fetus is delivered vaginally, the nurse implements fetal demise protocol and identification procedures. Which action is most important for the nurse to take?
- A. Create a memory box with the baby's footprint and photographs.
- B. Determine if the mother desires a visit from her clergy.
- C. Encourage the mother to hold and spend time with her baby.
- D. Explain the reasons for obtaining consent for an infant autopsy.
Correct answer: C
Rationale: Encouraging the mother to hold and spend time with her baby is crucial after a fetal demise at 32 weeks' gestation. This action can support the mother in the grieving process, facilitate bonding, and provide closure, helping her cope with the loss of the baby. Creating a memory box with the baby's footprint and photographs could be emotionally comforting but not as immediate and impactful as encouraging direct physical contact. While offering a visit from her clergy may provide spiritual support, the immediate need is to address the physical and emotional aspects of the situation. Explaining the reasons for obtaining consent for an infant autopsy is important, but it is secondary to the immediate emotional support needed by the mother.
5. During a routine prenatal health assessment for a client in her third trimester, the client reports that she had fluid leakage on her way to the appointment. Which technique should the nurse implement to evaluate the leakage?
- A. Insert a straight urinary catheter to drain the bladder.
- B. Scan the bladder for urinary retention.
- C. Palpate the suprapubic area for fetal head position.
- D. Test the fluid with a nitrazine strip.
Correct answer: D
Rationale: Testing the fluid with a nitrazine strip is the appropriate technique to differentiate between amniotic fluid and urine. This test helps in determining if the fluid leakage is amniotic fluid, which is crucial for guiding further management and ensuring appropriate care for the client during the third trimester of pregnancy. Inserting a straight urinary catheter to drain the bladder (Choice A) is unnecessary and invasive in this scenario as the concern is fluid leakage, not urinary retention. Scanning the bladder for urinary retention (Choice B) is also not indicated since the client reported fluid leakage, not retention. Palpating the suprapubic area for fetal head position (Choice C) is unrelated to assessing fluid leakage and not the appropriate technique in this situation.
