HESI Practice Test Pediatrics
1. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)
- A. 4.2 mL
- B. 5 mL
- C. 3.6 mL
- D. 4 mL
Correct answer: A
Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.
2. While assessing the vital signs of a 10-year-old who underwent a tonsillectomy this morning, the nurse observes the child swallowing every 2-3 minutes. Which assessment should the nurse implement?
- A. Inspect the posterior oropharynx
- B. Assess for teeth clenching or grinding
- C. Touch the tonsillar pillars to stimulate the gag reflex
- D. Ask the child to speak to evaluate a change in voice tone
Correct answer: A
Rationale: Frequent swallowing post-tonsillectomy may indicate bleeding. Inspecting the posterior oropharynx is essential to assess for any signs of bleeding, such as fresh blood or clots, which may necessitate immediate intervention. Option B is incorrect as teeth clenching or grinding is not directly related to the observation of frequent swallowing in this scenario. Option C is incorrect because stimulating the gag reflex is not necessary at this point and may be uncomfortable for the child. Option D is incorrect as evaluating a change in voice tone is not relevant to the situation of observing frequent swallowing.
3. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?
- A. Permanent lifestyle changes need to be made to promote safety in the home
- B. The chorea or movements are temporary and will eventually disappear
- C. Muscle tension is decreased with fine motor project skills, so these activities should be encouraged
- D. Consistent discipline is needed to help the child control the movements
Correct answer: C
Rationale: Chorea associated with rheumatic fever is usually temporary and will subside over time.
4. During a well-baby exam, a nurse finds that a 2-month-old's right testicle is not descended into the scrotum, but the left one is palpable. What should the nurse do?
- A. Ask if the right testis has been seen in the scrotum before
- B. Address potential concerns about future fertility
- C. Schedule an ultrasound to confirm the position of the testicle
- D. Prepare to obtain a urine specimen for culture
Correct answer: A
Rationale: The correct answer is to ask if the right testis has been seen in the scrotum before. The initial step in managing an undescended testicle is to determine if it has been previously observed in the scrotum or if this is a new finding. This information is crucial in deciding the next course of action. Choice B is incorrect because addressing future fertility concerns comes after confirming the status of the testicle. Choice C is unnecessary at this stage as the first step is to gather more history. Choice D is unrelated to the issue described and is not indicated in this scenario.
5. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (Proventil) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?
- A. When she last took the antihistamine.
- B. When her last asthma attack occurred.
- C. Duration of most asthma attacks.
- D. How often the MDI is used daily.
Correct answer: D
Rationale: The most important information for the nurse to obtain in this scenario is how often the MDI is used daily. This is crucial to assess if the symptoms the student is experiencing, such as insomnia, shakiness, and tachycardia, could be related to overuse of the inhaler. Overuse of albuterol can lead to side effects like tremors, palpitations, and difficulty sleeping, so understanding the frequency of MDI use is key in determining a potential cause for the student's symptoms. Options A, B, and C are not as pertinent in this situation as they do not directly address the possible link between the student's symptoms and the use of the albuterol MDI.
