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. A 15-month-old child is brought to the clinic for a routine checkup. The nurse notes that the child is not walking independently yet. What should the nurse do next?

A. Refer the child for a developmental assessment
B. Encourage the parents to start physical therapy
C. Reassure the parents that some children walk later than others
D. Discuss the importance of early intervention services

Correct answer: C

Rationale: The correct answer is to reassure the parents that some children walk later than others. It is essential to understand that children reach developmental milestones at different ages. Walking independently can occur later in some children, and it is normal. Referring the child for a developmental assessment (Choice A) may cause unnecessary concern at this stage. Encouraging physical therapy (Choice B) or discussing early intervention services (Choice D) may not be warranted unless there are specific concerns identified during the checkup.

3. The mother of a 14-year old who had a below-the-knee amputation for osteosarcoma tells the nurse that her child is angry and blaming her for allowing the amputation to occur. Which response is best for the nurse to provide?

A. I will ask the HCP for a psychiatric consult for your child'
B. This type of acting out behavior is normal for adolescents'
C. It is important to focus on your child’s needs at this difficult time'
D. A reaction of anger is your child’s attempt to cope with this loss'

Correct answer: D

Rationale: Acknowledging the child's anger as part of the coping process helps the mother understand her child's emotional response.

4. A child with acute lymphocytic leukemia (ALL) who is receiving chemotherapy via a subclavian IV infusion has an oral temperature of 103 degrees. In assessing the IV site, the nurse determines that there are no signs of infection at the site. Which intervention is the most important for the nurse to implement?

A. Obtain a specimen for blood cultures.
B. Assess the CBC.
C. Monitor the oral temperature every hour.
D. Administer acetaminophen as prescribed.

Correct answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

5. When reinforcing teaching with the parents of a 7-year-old child with attention-deficit/hyperactivity disorder (ADHD) about the child's medication, which statement by the parents indicates an understanding of the medication's side effects?

A. We should monitor our child's growth and appetite regularly.
B. The medication may cause drowsiness, so we will give it at bedtime.
C. We need to give the medication with food to avoid stomach upset.
D. The medication can cause increased urination, so fluid intake should be limited.

Correct answer: A

Rationale: The correct answer is A: 'We should monitor our child's growth and appetite regularly.' Correct monitoring of the child's growth and appetite is crucial when a child is on ADHD medications, especially stimulants, as these medications can have side effects related to growth and appetite. Monitoring these parameters regularly helps in assessing the medication's impact and making any necessary adjustments. Choices B, C, and D are incorrect: B talks about drowsiness, C mentions avoiding stomach upset, and D refers to increased urination and limiting fluid intake. While these are potential side effects of medications, they do not directly address the importance of monitoring growth and appetite, which is crucial in children on ADHD medications.
