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. Upon arrival in the nursery, a newborn infant is breathing satisfactorily but appears dusky. What action should the LPN/LVN take first?

• A. Notify the healthcare provider immediately.
• B. Suction the infant's nares, then the oral cavity.
• C. Check the infant's oxygen saturation rate.
• D. Position the infant on the right side.

Correct answer: C

Rationale: The priority action in this scenario is to check the infant's oxygen saturation rate. This will provide crucial information on the infant's oxygen levels and the need for immediate oxygen therapy. Assessing oxygen saturation is essential in determining the severity of hypoxia and guiding further interventions to ensure adequate oxygenation. Option A is not the priority as immediate intervention related to oxygenation is needed before notifying the healthcare provider. Suctioning (Option B) may be necessary but should come after assessing oxygen saturation. Positioning the infant (Option D) does not address the immediate need to evaluate oxygen levels.

3. 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.

4. The nurse is caring for a 2-day old neonate who has not passed meconium and has a swollen abdomen. The healthcare provider reviews the flat plate X-ray of the abdomen and makes a tentative diagnosis of Hirschsprung's disease. Which pathophysiological process is consistent with this neonate's clinical picture?

• A. The congenital absence of parasympathetic ganglion cells to large intestine produces no peristalsis.
• B. Pyloric obstruction causes reflux and projectile hematemesis.
• C. Partial imperforated anal opening limits passage of stools.
• D. Peristalsis moving against the intestinal obstruction causing hyperactivity of the bowel.

Correct answer: A

Rationale: Hirschsprung's disease is caused by the absence of parasympathetic ganglion cells in the large intestine, leading to a lack of peristalsis and obstruction.

5. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?

• A. Muscle tension decreases with fine motor skill projects, so these activities should be encouraged.
• B. The chorea or movements are temporary and will eventually disappear.
• C. Permanent lifestyle changes are not needed to promote safety in the home.
• D. Consistent discipline is not directly related to controlling the movements.

Correct answer: B

Rationale: Chorea, or sudden aimless movements associated with rheumatic fever, is temporary in nature and will eventually disappear on its own. It is important for the nurse to reassure the parents that these movements are part of the condition and typically resolve over time without the need for permanent lifestyle changes or strict discipline. Providing accurate information and reassurance to the parents can help alleviate concerns and promote understanding of the condition's course. Choices A, C, and D are incorrect because muscle tension, permanent lifestyle changes, and consistent discipline are not directly related to the resolution of chorea in rheumatic fever.
