HESI Practice Test Pediatrics
1. The practical nurse (PN) is caring for an adolescent who has been diagnosed with mononucleosis. Which activity should the PN advise the adolescent to avoid?
- A. Playing video games.
- B. Drinking caffeinated beverages.
- C. Participating in contact sports.
- D. Eating spicy foods.
Correct answer: C
Rationale: Contact sports should be avoided in mononucleosis due to the risk of spleen rupture, which is a serious complication of the disease. The spleen can enlarge in mononucleosis, making it more susceptible to injury from contact sports, potentially leading to a life-threatening situation if rupture occurs.
2. The heart rate for a 3-year-old with a congenital heart defect has steadily decreased over the last few hours, now it's 76 bpm, the previous reading 4 hours ago was 110 bpm. Which additional finding should be reported immediately to a healthcare provider?
- A. Oxygen saturation 94%.
- B. RR of 25 breaths/minute.
- C. Urine output 20 mL/hr.
- D. BP 70/40.
Correct answer: D
Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure may suggest poor cardiac output and compromised perfusion, requiring urgent medical attention. The other findings (oxygen saturation of 94%, RR of 25 breaths/minute, and urine output of 20 mL/hr) are within normal ranges for a 3-year-old and do not indicate immediate deterioration of the heart defect.
3. Which drink choice on a hot day indicates that a teenager with sickle cell anemia understands dietary considerations related to the disease?
- A. Milkshake
- B. Iced tea
- C. Diet cola
- D. Lemonade
Correct answer: D
Rationale: Lemonade is the correct choice for a teenager with sickle cell anemia as it provides hydration without caffeine, which is important for individuals with this condition. Caffeine can lead to dehydration, vasoconstriction, and potentially worsen symptoms in sickle cell anemia patients. Milkshake (choice A) may contain dairy, which can be high in fat and may not be the best choice for someone with sickle cell anemia. Iced tea (choice B) and diet cola (choice C) both contain caffeine, which should be avoided by individuals with sickle cell anemia due to its dehydrating effects.
4. 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.
5. A 9-year-old child is brought to the clinic with a fever, rash, and swollen joints. The nurse notes that the child had a sore throat two weeks ago that was not treated. What condition should the nurse suspect?
- A. Scarlet fever
- B. Rheumatic fever
- C. Kawasaki disease
- D. Juvenile rheumatoid arthritis
Correct answer: B
Rationale: In this scenario, the child's symptoms of fever, rash, and swollen joints following an untreated sore throat two weeks ago are indicative of rheumatic fever. Rheumatic fever can develop as a complication of untreated streptococcal infections, leading to systemic inflammation and affecting various organs, including the joints. This condition manifests with symptoms such as fever, rash, and swollen joints, aligning with the child's presentation in this case. Scarlet fever typically presents with a sandpapery rash and strawberry tongue but does not involve joint inflammation. Kawasaki disease presents with fever, rash, and mucous membrane changes but does not typically involve joint swelling. Juvenile rheumatoid arthritis can cause joint swelling but is not directly linked to a recent untreated sore throat.
