Nursing Elites

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

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

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?

• A. Betamethasone (Celestone) 12mg deep IM.
• B. Butorphanol 1mg IV push q2h PRN pain.
• C. Ampicillin 1g IV push q8h.
• D. Terbutaline (Brethine) 0.25mg subcutaneously q15 minutes x3.

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. After breastfeeding for 10 minutes at each breast, a new mother calls the nurse to the postpartum room to help change the newborn's diaper. As the mother begins the diaper change, the newborn spits up the breast milk. What action should the nurse implement first?

• A. Wipe away the spit-up and assist the mother with the diaper change.
• B. Sit the newborn upright and burp by rubbing or patting the upper back.
• C. Place the newborn in a position with the head lower than the feet.
• D. Turn the newborn to the side and use bulb suction for the mouth and nares.

Correct answer: B

Rationale: After a newborn spits up breast milk following feeding, the priority action for the nurse is to sit the newborn upright and burp by rubbing or patting the upper back. This position helps release trapped air and reduces the likelihood of further spit-up or aspiration. It is essential to address this first to prevent potential complications and ensure the newborn's comfort and safety.

4. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

• A. Massage the calf and foot.
• B. Extend the leg and dorsiflex the foot.
• C. Lower the leg off the side of the bed.
• D. Elevate the leg above the heart.

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.

5. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.
