HESI Practice Test Pediatrics
1. When observing a distraught mother scolding her 3-year-old son for wetting his pants in the hallway of a pediatric unit, what initial action should the nurse take?
- A. Suggest that the mother consult a pediatric nephrologist.
- B. Provide disposable training pants while calming the mother.
- C. Refer the mother to a community parent education program.
- D. Inform the mother that toilet training is slower for boys.
Correct answer: B
Rationale: In this situation, the nurse's initial action should be to provide disposable training pants to manage the immediate issue of wetting while also calming the mother. This approach addresses the current distressing situation and offers a practical solution to alleviate the mother's concerns.
2. The healthcare provider plans to administer 10 mcg/kg of digoxin elixir as a loading dose to a child who weighs 55 pounds. Digoxin is available as an elixir of 50 mcg/ml. How many milliliters of the digoxin elixir should the healthcare provider administer to this child?
- A. 5 ml
- B. 10 ml
- C. 15 ml
- D. 20 ml
Correct answer: A
Rationale: To calculate the dose, first, convert the child's weight to kilograms by dividing 55 pounds by 2.2, which equals approximately 25 kg. Then, multiply the weight by the dose (10 mcg/kg) to get the total dose needed, which is 250 mcg. Next, divide the total dose by the concentration of the elixir (50 mcg/ml) to determine the volume needed, which is 5 ml. Therefore, the correct dose is 5 ml based on the child's weight and the concentration of the elixir.
3. A 3-year-old child is admitted to the hospital with severe dehydration. The healthcare provider prescribes an IV infusion of 0.9% normal saline. The nurse notes that the child’s heart rate is 150 beats per minute, and the blood pressure is 90/50 mm Hg. What should the nurse do first?
- A. Administer the IV fluids as prescribed
- B. Notify the healthcare provider
- C. Check the child’s urine output
- D. Reassess the child’s vital signs in 30 minutes
Correct answer: A
Rationale: In a pediatric patient with severe dehydration and signs of compromised hemodynamics such as tachycardia (heart rate of 150 bpm) and hypotension (blood pressure of 90/50 mm Hg), the priority intervention is to administer IV fluids as prescribed. Immediate fluid resuscitation is essential to restore hydration, improve perfusion, and stabilize the child's vital signs. While it's important to monitor urine output, initiating fluid resuscitation takes precedence in this situation. Notifying the healthcare provider can cause a delay in critical intervention, and waiting to reassess vital signs in 30 minutes can be detrimental in a child with severe dehydration and compromised hemodynamics.
4. A 4-year-old child is brought to the clinic with complaints of ear pain and fever. The practical nurse suspects otitis media. Which symptom supports this suspicion?
- A. Clear nasal discharge.
- B. Dry, hacking cough.
- C. Tugging at the ear.
- D. Sore throat.
Correct answer: C
Rationale: Tugging at the ear is a common symptom in children with otitis media. It often indicates discomfort or pain in the ear, suggesting inflammation or infection in the middle ear. This behavior is frequently observed in young children who are unable to express their discomfort verbally, making it a significant clinical indicator for otitis media in this age group. Clear nasal discharge (Choice A) is more indicative of a cold or allergies, while a dry, hacking cough (Choice B) is not typically associated with otitis media. Although a sore throat (Choice D) can sometimes accompany ear infections, tugging at the ear is a more specific and reliable symptom in this case.
5. 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.
