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. An adolescent female who comes to the school clinic is reluctant to confide her concerns to the practical nurse (PN). The PN tells the teen that confidentiality and privacy are maintained unless a life-threatening situation arises. Which principle supports the PN's response?

• A. The adolescent should be encouraged to seek help outside of the school clinic.
• B. Disclosures from the adolescent should be kept confidential.
• C. Honest information ensures establishing a trusting relationship.
• D. Minor adolescents should not be encouraged to disclose private concerns.

Correct answer: C

Rationale: The correct principle supporting the practical nurse's response is that honest information ensures establishing a trusting relationship. By assuring confidentiality and privacy to the adolescent unless there is a life-threatening situation, the practical nurse fosters an environment where the teen feels safe to share their concerns openly. This approach helps build trust, encouraging effective communication and support for the adolescent's well-being. Choices A, B, and D are incorrect because encouraging seeking help outside the school clinic, keeping disclosures confidential, and discouraging minor adolescents from sharing private concerns do not address the immediate need to build trust and ensure the well-being of the adolescent in a school setting.

3. A child with sickle cell anemia is being treated for a vaso-occlusive crisis. Which intervention should the practical nurse (PN) implement?

• A. Apply cold packs to painful areas.
• B. Encourage increased fluid intake.
• C. Administer high doses of vitamin C.
• D. Provide low-calorie meals.

Correct answer: B

Rationale: Encouraging increased fluid intake is crucial in managing vaso-occlusive crises in patients with sickle cell anemia. Dehydration can worsen these crises, so adequate hydration is essential to prevent complications and improve outcomes. Applying cold packs to painful areas may exacerbate vaso-occlusive crises by causing vasoconstriction. Administering high doses of vitamin C is not directly indicated for vaso-occlusive crises in sickle cell anemia. Providing low-calorie meals is not the priority during a vaso-occlusive crisis; maintaining adequate nutrition is important, but hydration takes precedence in this situation.

4. A child who weighs 25 kg is receiving IV ampicillin 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

• A. 1875 mg
• B. 625 mg
• C. 2000 mg
• D. 1500 mg

Correct answer: A

Rationale: To calculate the dose for each administration, multiply the child's weight (25 kg) by the dose (300 mg/kg/24 hours) and divide by the number of doses per day (6, as doses are every 4 hours). This gives us (25 kg * 300 mg/kg / 24 hours) / 6 doses = 1875 mg. Therefore, the nurse should administer 1875 mg for each dose. Choice B, 625 mg, is incorrect as it does not consider the correct calculation based on the weight and prescribed dose. Choice C, 2000 mg, is incorrect as it is not derived from the correct dosage calculation. Choice D, 1500 mg, is incorrect as it does not reflect the accurate dosage calculation based on the weight of the child and the prescribed dose.

5. What should the nurse do first for a 6-year-old with asthma showing a prolonged expiratory phase, wheezing, and 35% of personal best peak expiratory flow rate (PEFR)?

• A. Administer a prescribed bronchodilator.
• B. Encourage the child to cough and take deep breaths.
• C. Report the findings to the healthcare provider.
• D. Identify the triggers that precipitated this attack.

Correct answer: A

Rationale: Administering a bronchodilator is the priority action in managing an acute asthma exacerbation in a child. Bronchodilators help to relax the muscles around the airways, opening them up and improving breathing. This intervention aims to address the immediate breathing difficulty and should be done promptly to provide relief for the child. Encouraging coughing and deep breaths (choice B) may worsen the child's condition by further constricting the airways. Reporting findings to the healthcare provider (choice C) is important but not the immediate priority in this acute situation. Identifying triggers (choice D) is crucial for long-term asthma management but is not the first step when managing an acute exacerbation.
