HESI Pediatric Practice Exam
1. 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.
2. 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.
3. A 4-year-old child with a history of asthma is brought to the clinic with a complaint of cough and wheezing. The nurse notes that the child has been using a rescue inhaler more frequently over the past week. What should the nurse do next?
- A. Review the child’s asthma action plan
- B. Administer a dose of the rescue inhaler
- C. Instruct the parents to increase the dose of the controller medication
- D. Schedule a follow-up appointment in one week
Correct answer: A
Rationale: In this scenario, the best course of action for the nurse is to review the child's asthma action plan. By doing so, the nurse can assess the current asthma management, ensure that the child is using the rescue inhaler correctly, and make any necessary adjustments to the treatment plan. Reviewing the asthma action plan helps in identifying triggers, proper use of medications, and when to seek medical help. Administering a dose of the rescue inhaler without assessing the current management plan may not address the underlying issue. Instructing the parents to increase the dose of the controller medication without proper evaluation can lead to inappropriate medication adjustments. Scheduling a follow-up appointment in one week is not the immediate action needed to address the child's current symptoms.
4. A child who weighs 25 kg is receiving IV ampicillin at a dose of 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 correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.
5. A 2-year-old girl is brought to the clinic by her 17-year-old mother. When the nurse observes that the child is drinking sweetened soda from her bottle, what information should the nurse discuss with this mother?
- A. A 2-year-old should be speaking in 2-word phrases
- B. Dental caries is associated with drinking soda
- C. Drinking soda is related to childhood obesity
- D. Toddlers should be sleeping 10 hours a night
Correct answer: B
Rationale: Dental caries are a common concern when children consume sweetened sodas regularly.
