Maternity HESI Quizlet

HESI RN

1. The LPN/LVN should explain to a 30-year-old gravida client that alpha fetoprotein testing is recommended for which purpose?

A. Detect cardiovascular disorders.
B. Screen for neural tube defects.
C. Monitor placental functioning.
D. Assess for maternal pre-eclampsia.

Correct answer: B

Rationale: The correct answer is B: Screen for neural tube defects. Alpha fetoprotein testing is primarily used to screen for neural tube defects and other fetal abnormalities. It is not used to detect cardiovascular disorders, monitor placental functioning, or assess for maternal pre-eclampsia.

2. While caring for a laboring client on continuous fetal monitoring, the nurse notes a fetal heart rate pattern that falls and rises abruptly with a 'V' shaped appearance. What action should the nurse take first?

A. Change the maternal position.
B. Administer oxygen at 10 L by mask.
C. Prepare for a potential cesarean.
D. Allow the client to begin pushing.

Correct answer: A

Rationale: In cases of fetal heart rate patterns showing abrupt falls and rises with a 'V' shaped appearance, it indicates possible cord compression. Changing the maternal position, such as moving the mother onto her side, can relieve the pressure off the cord and help improve fetal oxygenation, making it the priority intervention to address the decelerations.

3. One hour after giving birth to an 8-pound infant, a client's lochia rubra has increased from small to large, and her fundus is boggy despite massage. The client's pulse is 84 beats/minute, and blood pressure is 156/96. The healthcare provider prescribes Methergine 0.2 mg IM × 1. What action should the healthcare provider take immediately?

A. Give the medication as prescribed and monitor for efficacy.
B. Encourage the client to breastfeed rather than bottle-feed.
C. Have the client empty her bladder and massage the fundus.
D. Call the healthcare provider to question the prescription.

Correct answer: D

Rationale: The correct action for the healthcare provider to take immediately is to call the healthcare provider to question the prescription. Methergine is contraindicated in clients with hypertension due to its potential to elevate blood pressure further. In this scenario, the client's blood pressure is already elevated at 156/96, making it unsafe to administer Methergine. The LPN/LVN should advocate for the client's safety by questioning the prescription to prevent potential harm.

4. The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child’s weight?

A. 10mL
B. 15mL
C. 7.5mL
D. 5mL

Correct answer: A

Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs ÷ 2.2 = 10 kg. The maximum dose based on weight would be 10 kg × 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg ÷ 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg ÷ 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.

5. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?

A. Provide a bottle of electrolyte solution.
B. Infuse normal saline intravenously.
C. Administer an antipyretic rectally.
D. Apply an external cooling blanket.

Correct answer: B

Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.
