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. Which developmental behavior should the practical nurse identify as normal for a 6-month-old infant?

• A. Rolls over completely.
• B. Creeps on all fours.
• C. Pulls self to a standing position.
• D. Assumes a sitting position independently.

Correct answer: A

Rationale: The correct answer is A: 'Rolls over completely.' By 6 months of age, infants typically achieve the milestone of rolling over completely. This ability demonstrates increasing strength and coordination. Creeping on all fours, pulling self to a standing position, and assuming a sitting position independently are skills that are usually developed at later stages of infancy. Creeping usually occurs around 9-10 months, pulling self to a standing position around 9-12 months, and assuming a sitting position independently around 8 months. Therefore, at 6 months, rolling over completely is the most expected developmental behavior.

3. A 2-year-old is admitted to the hospital with possible encephalitis, and a lumbar puncture is scheduled. Which information should the nurse provide this child concerning the procedure?

• A. Describe the side-lying, knees-to-chest position that must be assumed during the procedure.
• B. Explain that fluids cannot be taken for 8 hours before the procedure and for 4 hours after the procedure.
• C. Reassure the child that there will be no restrictions on activity after the procedure is completed.
• D. Tell the child to expect loud clicking noises during the procedure that may be slightly annoying.

Correct answer: A

Rationale: Children, especially young ones, benefit from knowing what position they will be in during a procedure as it helps them understand and feel more in control. Describing the side-lying, knees-to-chest position can reduce anxiety and promote cooperation during the lumbar puncture. Choice B is incorrect because the question is about preparing the child for the procedure, not about pre-procedure fasting requirements. Choice C is incorrect because there may be restrictions on activity after the procedure. Choice D is incorrect because mentioning loud clicking noises may increase the child's anxiety and fear.

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. The nurse is caring for a 4-year-old child who is hospitalized with pneumonia. The child is receiving IV antibiotics and oxygen therapy. The nurse notes that the child’s respiratory rate is 40 breaths per minute, and the oxygen saturation is 92%. What is the nurse’s priority action?

• A. Increase the child’s oxygen flow rate
• B. Notify the healthcare provider
• C. Encourage the child to take deep breaths
• D. Auscultate the child’s lung sounds

Correct answer: D

Rationale: In this scenario, the child is hospitalized with pneumonia, receiving IV antibiotics and oxygen therapy. With a high respiratory rate and decreased oxygen saturation, auscultating the child’s lung sounds is the priority action. This assessment can provide crucial information about the child’s respiratory status, such as the presence of adventitious sounds or decreased air entry, which can guide further interventions and help in evaluating the effectiveness of the current treatments. Increasing the oxygen flow rate may not address the underlying issue causing the decreased oxygen saturation. Notifying the healthcare provider can be necessary but auscultating lung sounds should be done first to gather more information. Encouraging the child to take deep breaths is important for respiratory function but should not be the immediate priority in this situation.
