HESI Pediatrics Practice Exam
1. When screening a 5-year-old for strabismus, what action should the nurse take?
- A. Have the child identify colored patterns on polychromatic cards.
- B. Direct the child through the six cardinal positions of gaze.
- C. Inspect the child for the setting sun sign.
- D. Observe the child for blank, sunken eyes.
Correct answer: B
Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.
2. What is the correct procedure for performing an ophthalmoscopic examination on a client's right retina?
- A. Instruct the client to focus on a distant object behind the examiner and not move their eyes during the exam.
- B. Set the ophthalmoscope on the plus 2 to 3 lens and hold it in front of the examiner's right eye.
- C. From a distance of 12 to 15 inches and slightly to the side, shine the light into the client's pupil.
- D. For optimal visualization, keep the ophthalmoscope at least 3 inches from the client's eye.
Correct answer: C
Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.
3. The nurse notices that the influenza immunization rate is much lower for certain demographic groups than for others. Which intervention is likely to be most useful in increasing the rates of immunization in the underserved community groups?
- A. designated clinics conveniently located in target neighborhoods
- B. reports on decreasing influenza rates during times of greatest prevalence
- C. legislative proposals that mandate influenza vaccinations for all
- D. radio announcements about the availability of the influenza vaccine
Correct answer: A
Rationale: Conveniently located clinics in target neighborhoods increase accessibility, making it easier for underserved community groups to receive influenza immunizations. This intervention directly addresses the issue of lower immunization rates by improving convenience and access. Reports on decreasing influenza rates (choice B) may not directly impact immunization rates. Legislative proposals mandating vaccinations (choice C) could face resistance and may not always be the most effective or practical solution. Radio announcements (choice D) may raise awareness but may not address the underlying barriers to immunization faced by underserved communities.
4. The nurse is developing a plan of care for a client who reports tingling in the feet and who is newly diagnosed with peripheral vascular disease. Which outcome should the nurse include in the plan of care for this client?
- A. The client will walk 30 minutes three times a week
- B. The client will demonstrate understanding of proper shoe fit
- C. The client will perform foot care daily
- D. The client's blood pressure readings will be less than 160/90 mmHg
Correct answer: D
Rationale: Controlling blood pressure is critical in managing peripheral vascular disease, as elevated pressure can exacerbate vascular damage and complications. While foot care, shoe fit, and exercise are important, lowering blood pressure is a primary goal. Proper blood pressure management helps in preventing further damage to the blood vessels and reduces the risk of complications associated with peripheral vascular disease, making it the most crucial outcome to include in the plan of care for this client.
5. After a client has an enteral feeding tube inserted, the most accurate method for verification of placement is
- A. Abdominal x-ray
- B. Auscultation
- C. Flushing tube with saline
- D. Aspiration for gastric contents
Correct answer: D
Rationale: After the insertion of an enteral feeding tube, the most accurate method for verifying its placement is by aspirating gastric contents. This method ensures that the tube is correctly positioned in the stomach. Abdominal x-ray can provide additional confirmation but is not as immediate or practical. Auscultation and flushing the tube with saline are not as reliable as aspirating gastric contents for verifying proper placement of an enteral feeding tube.
