Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

2. The parents of a 10-year-old child with newly diagnosed type 1 diabetes are being taught by the nurse about managing their child’s condition. Which statement by the parents indicates they need further teaching?

• A. We should rotate injection sites to prevent tissue damage
• B. Our child should avoid all sugary foods and drinks
• C. We will monitor blood glucose levels regularly
• D. Our child needs to wear a medical alert bracelet

Correct answer: B

Rationale: It is important for individuals with diabetes to manage their carbohydrate intake, including sugary foods and drinks, rather than completely avoiding them. Sugary foods should be consumed in moderation as part of a balanced diet to help maintain stable blood glucose levels.

3. A 3-year-old child is admitted to the hospital with a diagnosis of pneumonia. The nurse notes that the child has a fever and is breathing rapidly. What is the nurse’s priority action?

• A. Administer antipyretic medication
• B. Obtain a chest X-ray
• C. Start the child on oxygen therapy
• D. Notify the healthcare provider

Correct answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.

4. When observing a distraught mother scolding her 3-year-old son for wetting his pants in the hallway of a pediatric unit, what initial action should the nurse take?

• A. Suggest that the mother consult a pediatric nephrologist.
• B. Provide disposable training pants while calming the mother.
• C. Refer the mother to a community parent education program.
• D. Inform the mother that toilet training is slower for boys.

Correct answer: B

Rationale: In this situation, the nurse's initial action should be to provide disposable training pants to manage the immediate issue of wetting while also calming the mother. This approach addresses the current distressing situation and offers a practical solution to alleviate the mother's concerns.

5. When instilling ear drops in a 2-year-old child, how should the practical nurse (PN) position the earlobe to straighten the external auditory canal?

• A. Up and back.
• B. Down and back.
• C. Up and forward.
• D. Down and forward.

Correct answer: B

Rationale: When administering ear drops to a child under three years old, it is essential to pull the earlobe down and back. This positioning helps straighten the external auditory canal, facilitating the proper administration of the ear drops. Pulling the earlobe down and back in young children aims to ensure that the medication reaches the intended area for optimal effectiveness.
