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 coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. A child with pertussis is receiving azithromycin (Zithromax Injection) IV. Which intervention is most important for the nurse to include in the child's plan of care?

• A. Obtain vital signs to monitor for fluid overload
• B. Change IV site dressing every 3 days and as needed
• C. Monitor for signs of facial swelling or urticaria
• D. Assess for abdominal pain and vomiting

Correct answer: C

Rationale: When administering azithromycin IV, monitoring for signs of an allergic reaction, such as facial swelling or urticaria, is crucial. This helps in early detection of potential adverse reactions and ensures prompt intervention to prevent complications associated with the medication. The other options are not directly related to the administration of azithromycin IV in this scenario. Monitoring for fluid overload would be more relevant for fluid administration, changing IV site dressing is important but not the priority in this case, and assessing for abdominal pain and vomiting may be important but not as critical as monitoring for signs of an allergic reaction.

3. During a well-baby check of a 7-month-old infant, the practical nurse notes an absence of babbling. Which focused assessment should the PN implement?

• A. Visual function.
• B. Auditory function.
• C. Cognitive function.
• D. Social development.

Correct answer: B

Rationale: The absence of babbling in a 7-month-old infant is a concerning auditory development milestone. Babbling is an early stage of language development that involves making various sounds. A lack of babbling could indicate a hearing impairment or other auditory issues. Therefore, the practical nurse should focus on assessing the infant's auditory function to determine if further evaluation or intervention is necessary. Choices A, C, and D are incorrect because the absence of babbling specifically points towards a potential issue related to auditory function rather than visual, cognitive, or social development.

4. A 5-year-old child with leukemia is receiving chemotherapy. The nurse notes that the child’s white blood cell count is low. What is the nurse’s priority intervention?

• A. Administer antibiotics as prescribed
• B. Place the child in protective isolation
• C. Encourage the child to eat a balanced diet
• D. Teach the parents about infection prevention

Correct answer: B

Rationale: The priority intervention for a 5-year-old child with leukemia receiving chemotherapy and having a low white blood cell count is to place the child in protective isolation. This intervention helps reduce the risk of infection, which is crucial in this immunocompromised state. Protective isolation aims to limit the child's exposure to pathogens and promote their safety during a period of increased vulnerability to infections.

5. What information should the nurse provide the parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) who are concerned about having more children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
• B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
• C. The mother's lack of the protein dystrophin can impact the XXXX muscle groups in males.
• D. Birth trauma during a breech vaginal birth can damage the spinal cord, resulting in muscle weakness.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an inherited X-linked recessive disorder that primarily affects male children in the family. Since it is X-linked, sons inherit the mutation from their mothers who are carriers of the abnormal gene. Therefore, the nurse should explain to the parents that any future sons they have would have a 50% chance of inheriting the mutation and having DMD, while daughters would have a 50% chance of being carriers like the mother.
