1. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.

2. In planning care for a client at 30-weeks gestation experiencing preterm labor, what maternal prescription is most important in preventing this fetus from developing respiratory syndrome?

Correct answer: A

Rationale: The administration of Betamethasone (Celestone) is crucial in cases of preterm labor to promote fetal lung maturation and reduce the risk of respiratory distress syndrome in the newborn. Betamethasone helps enhance the production of surfactant in the fetal lungs, improving their functionality and decreasing the likelihood of respiratory complications upon birth. Butorphanol is an analgesic and not indicated for preventing respiratory syndrome in preterm infants. Ampicillin is an antibiotic used for infection prevention and treatment, not for fetal lung maturation. Terbutaline is a tocolytic agent used to inhibit contractions, but it does not have a direct effect on fetal lung maturity.

3. 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?

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.

4. 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?

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.

5. The healthcare provider is preparing to suture a 10-year-old with a lacerated forehead. Both parents and the 12-year-old sibling are at the child’s bedside. Which instruction best supports the family?

Correct answer: D

Rationale: Choice D is the best instruction as it involves the family in the decision-making process, allowing them to choose who will stay with the child during the suturing procedure. This approach supports the family's comfort and participation in the child's care, promoting a sense of control and family-centered care. Choices A, B, and C do not promote family involvement and may lead to feelings of exclusion or lack of control among the family members.
