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. A new mother calls the nurse stating that she wants to start feeding her 6-month-old child something besides breast milk, but is concerned that the infant is too young to start eating solid foods. How should the nurse respond?

• A. Advise the mother to wait at least another month before starting any solid foods.
• B. Instruct the mother to offer a few spoons of 2 or 3 pureed fruits at each meal.
• C. Reassure the mother that the infant is old enough to eat iron-fortified cereal.
• D. Encourage the mother to schedule a developmental assessment of the infant.

Correct answer: C

Rationale: At 6 months, infants are generally ready to start eating iron-fortified cereals as their iron stores begin to deplete. Introducing iron-fortified cereals at this age helps meet the infant's nutritional needs, particularly for iron, which becomes deficient as the infant's iron reserves diminish. It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding. Choice A is incorrect because waiting another month is not necessary if the infant is 6 months old. Choice B is incorrect as introducing pureed fruits as the first food may not provide the necessary iron that the infant needs at this stage. Choice D is also incorrect as scheduling a developmental assessment is not indicated solely based on the desire to start solid foods; it is more appropriate to reassure the mother about starting iron-fortified cereal.

3. Assessment findings of a 4-hour-old newborn include: axillary temperature of 96.8°F (35.8°C), heart rate of 150 beats/minute with a soft murmur, irregular respiratory rate at 64 breaths/minute, jitteriness, hypotonia, and weak cry. Based on these findings, which action should the nurse implement?

• A. Swaddle the infant in a warm blanket.
• B. Obtain a heel stick blood glucose level.
• C. Place a pulse oximeter on the heel.
• D. Document the findings in the record.

Correct answer: B

Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.

4. A client who is receiving oxytocin to augment early labor begins to experience tachysystolic tetanic contractions with variable fetal heart decelerations. Which action should the nurse implement?

• A. Turn off the oxytocin infusion.
• B. Reposition the fetal monitor transducers.
• C. Decrease the rate of the oxytocin infusion.
• D. Alert the charge nurse about the patient's condition.

Correct answer: A

Rationale: When a client experiences tachysystolic tetanic contractions with variable fetal heart decelerations, indicating uterine hyperstimulation, the priority action is to turn off the oxytocin infusion. This step aims to reduce uterine activity, which can compromise fetal oxygenation and lead to adverse outcomes.

5. 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.
