Pediatric HESI Practice Questions
1. A parent calls the outpatient clinic requesting information about the appropriate dose of acetaminophen for a 16-month-old child who has signs of an upper respiratory tract infection and fever. The directions on the bottle of acetaminophen elixir are 120 mg every 4 hours when needed. At the toddler’s 15-month visit, the health care provider prescribed 150 mg. What is the nurse’s best response to the parent?
- A. “The dose is close enough, and it doesn’t really matter which one is given.”
- B. “From your description, the medications are not necessary. They should be avoided at this age.”
- C. “It is appropriate to use dosages based on age. Children typically have weights consistent for their age groups.”
- D. “The prescribed dose of the drug was based on weight, and this is a more accurate way of determining a therapeutic dose.”
Correct answer: D
Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing helps ensure that the child receives the appropriate amount of medication for their body size, which is crucial for safety and effectiveness. Age-based dosing can lead to underdosing or overdosing, as children of the same age can have significantly different weights. Choice A is incorrect because even small variations in dosages can have significant effects on a child's health. Choice B is incorrect as acetaminophen can be appropriate when used correctly for fever management in children. Choice C is incorrect as children's weights can vary greatly within the same age group, making weight-based dosing more precise and individualized.
2. What is an important nursing responsibility when a dysrhythmia is suspected?
- A. Order an immediate electrocardiogram
- B. Count the radial pulse every minute for five times
- C. Count the apical pulse for 1 full minute and compare the rate with the radial pulse rate
- D. Have someone else take the radial pulse simultaneously with the apical pulse
Correct answer: C
Rationale: When a dysrhythmia is suspected, it is important for nurses to count the apical pulse for a full minute and compare it with the radial pulse rate. This method helps in identifying dysrhythmias because discrepancies between the apical and radial pulse rates can indicate irregular heart rhythms. Option A is incorrect because ordering an immediate electrocardiogram may not always be feasible or necessary as a first step. Option B, counting the radial pulse multiple times, is less accurate than comparing the apical and radial pulse rates. Option D involves an unnecessary step of having another person take simultaneous pulses when the nurse can do it effectively alone.
3. A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?
- A. Low tissue oxygen needs
- B. Tissue oxygen needs
- C. Diminished iron levels
- D. Hypertrophic cardiac muscle
Correct answer: B
Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.
4. The nurse is admitting a newborn with hypospadias to the nursery. The nurse expects which finding in this newborn?
- A. absence of a urethral opening
- B. penis appears shorter than usual for age
- C. the urethral opening is along the dorsal surface of the penis
- D. the urethral opening is along the ventral surface of the penis
Correct answer: D
Rationale: Hypospadias is a congenital condition where the urethral opening is located along the ventral surface of the penis, not the dorsal surface (Choice C) or absent (Choice A). This leads to the characteristic appearance of a ventrally displaced urethral meatus. The penis may appear normal in size but with the urethral opening positioned abnormally (Choice D), rather than being shorter than usual (Choice B). Therefore, the correct expectation for a newborn with hypospadias is that the urethral opening is along the ventral surface of the penis, making Choice D the correct answer.
5. The nurse is planning a discussion group for parents with children who have cancer. How would the nurse describe a difference between cancer in children and adults?
- A. Most childhood cancers affect tissues rather than organs.
- B. Childhood cancers are usually localized when found.
- C. Unlike adult cancers, childhood cancers are less responsive to treatment.
- D. The majority of childhood cancers can be prevented.
Correct answer: A
Rationale: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers can be localized or spread, similar to adult cancers. Choice C is incorrect because childhood cancers can be highly responsive to treatment, especially when diagnosed early. Choice D is incorrect because the majority of childhood cancers cannot be prevented as they are often due to genetic mutations or unknown causes.
