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 14-year-old adolescent with a history of substance abuse is brought to the emergency department by the parents, who suspect that the adolescent has relapsed. What is the nurse’s priority action?

• A. Obtain a urine sample for toxicology screening
• B. Discuss treatment options with the parents
• C. Establish a therapeutic relationship with the adolescent
• D. Administer a medication to reverse the effects of the substance

Correct answer: A

Rationale: In this scenario, the nurse's priority action should be to obtain a urine sample for toxicology screening. This step is crucial in identifying the substances involved in the relapse, which will guide appropriate treatment strategies. By knowing the specific substances, healthcare providers can tailor treatment plans effectively. Establishing a therapeutic relationship and discussing treatment options come after obtaining necessary diagnostic information to ensure a comprehensive care plan. Administering a medication to reverse substance effects is not the initial priority; identification of the substances through toxicology screening should precede any treatment intervention.

3. A child with a fever of 39°C (102.2°F) and a sore throat is brought to the clinic. The practical nurse suspects the child has streptococcal pharyngitis. Which diagnostic test should the practical nurse prepare the child for?

• A. Rapid antigen detection test.
• B. Throat culture.
• C. Complete blood count (CBC).
• D. Chest X-ray.

Correct answer: A

Rationale: A rapid antigen detection test is the appropriate diagnostic test for suspected streptococcal pharyngitis. This test is commonly used due to its quick results, helping in the prompt diagnosis and appropriate treatment of the condition. It specifically detects the presence of streptococcal antigens in the throat, aiding in confirming the diagnosis and guiding the healthcare provider in determining the most suitable treatment plan. Throat culture (Choice B) is a confirmatory test but is not as rapid as the rapid antigen detection test. Complete blood count (Choice C) and Chest X-ray (Choice D) are not specific tests for streptococcal pharyngitis and would not aid in confirming the diagnosis.

4. What information should a nurse discuss with the mother of a 2-year-old girl who is drinking sweetened soda from her bottle?

• A. Encouraging 2-word phrases in speech development for a 2-year-old
• B. Explaining the association between drinking soda and dental caries
• C. Discussing the link between drinking soda and childhood obesity
• D. Emphasizing the importance of toddlers sleeping 10 hours a night

Correct answer: B

Rationale: The correct answer is explaining the association between drinking soda and dental caries. Soda consumption can lead to tooth decay and cavities, so it is crucial to educate the mother about this to prevent dental issues in the child.

5. A 4-month-old girl is brought to the clinic by her mother because she has had a cold for 2 to 3 days and woke up this morning with a hacking cough and difficulty breathing. Which additional assessment finding should alert the nurse that the child is in acute respiratory distress?

• A. Bilateral bronchial breath sounds.
• B. Diaphragmatic respiration.
• C. A resting respiratory rate of 35 breaths per minute.
• D. Flaring of the nares.

Correct answer: D

Rationale: Flaring of the nares is a clinical sign of acute respiratory distress in infants. It indicates an increased effort to breathe and is a crucial finding that requires immediate attention, as it signifies the child is having difficulty breathing and may be in respiratory distress. Choices A, B, and C are incorrect. Bilateral bronchial breath sounds may be present in conditions like pneumonia but do not specifically indicate acute respiratory distress. Diaphragmatic respiration is a normal breathing pattern and not a sign of distress. A resting respiratory rate of 35 breaths per minute in a 4-month-old infant is within the expected range, so it does not necessarily indicate acute respiratory distress.
