HESI RN
HESI Pediatric Practice Exam
1. During a well baby visit, the parents explain that a soft bulge appears in the groin of their 4-month-old son when he cries or strains during stooling. The infant is scheduled for surgical repair of the inguinal hernia in two weeks. What should the parent be instructed to do if the hernia becomes incarcerated prior to the surgery?
- A. Use a rectal thermometer to strain during stooling.
- B. Gently manipulate the hernia for reduction.
- C. Offer oral electrolyte fluids for comfort.
- D. Give acetaminophen or aspirin for crying.
Correct answer: B
Rationale: In the case of an incarcerated inguinal hernia, gentle manipulation can sometimes help in reducing it before surgery. This action should be taken cautiously and immediately followed by seeking medical attention. It is important to note that attempting reduction should be done by a healthcare professional, and parents should be advised to seek urgent medical care if the hernia becomes incarcerated. Using a rectal thermometer to strain during stooling (Choice A) is not the correct approach for an incarcerated hernia and can worsen the condition. Offering oral electrolyte fluids for comfort (Choice C) or giving acetaminophen or aspirin for crying (Choice D) are not appropriate interventions for an incarcerated hernia and may delay necessary medical treatment.
2. During a client assessment, the healthcare provider is evaluating cranial nerve function. Which assessment finding suggests that cranial nerve II is intact?
- A. The client can hear a whisper from 1 to 2 feet away.
- B. The client can identify an object by touch.
- C. The client can shrug the shoulders against resistance.
- D. The client can read a Snellen chart from 20 feet away.
Correct answer: D
Rationale: The ability to read a Snellen chart from 20 feet away indicates intact cranial nerve II (optic nerve), responsible for vision. Hearing a whisper (A) is associated with cranial nerve VIII (vestibulocochlear nerve), identifying an object by touch (B) is related to cranial nerves V (trigeminal nerve) and VII (facial nerve), and shoulder shrugging against resistance (C) is a test for cranial nerve XI (accessory nerve). Thus, the correct answer is D as it specifically tests the function of cranial nerve II.
3. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding requires immediate intervention?
- A. Oxygen saturation of 88%.
- B. Use of accessory muscles for breathing.
- C. Respiratory rate of 26 breaths per minute.
- D. Barrel-shaped chest.
Correct answer: C
Rationale: A respiratory rate of 26 breaths per minute is an abnormal finding and indicates that the client is experiencing respiratory distress, requiring immediate intervention. This rapid respiratory rate can signify inadequate oxygenation and ventilation. Oxygen saturation of 88% is low but not as immediately concerning as a high respiratory rate, which indicates the body is compensating for respiratory distress. The use of accessory muscles for breathing and a barrel-shaped chest are typical findings in clients with COPD but do not indicate an immediate need for intervention as they are more chronic in nature and may be seen in stable COPD patients.
4. What is the science of biological classification commonly called?
- A. Taxonomy
- B. Physiology
- C. Botany
- D. Zoology
Correct answer: A
Rationale: Taxonomy is the science of naming, defining, and classifying groups of biological organisms based on shared characteristics. Physiology (choice B) is the study of the functions and processes of living organisms, not classification. Botany (choice C) is the study of plants, while Zoology (choice D) is the study of animals. Therefore, the correct answer is Taxonomy (choice A).
5. In which step of cellular respiration is the most adenosine triphosphate (ATP) created?
- A. Electron transport chain
- B. Glycolysis
- C. Citric acid cycle (the Krebs cycle)
- D. All of these produce equal amounts of ATP
Correct answer: A
Rationale: The electron transport chain is the step in cellular respiration that generates the most ATP. During this step, up to 34 ATP molecules can be produced from a single glucose molecule. Choice B, Glycolysis, produces a smaller amount of ATP (2 ATP molecules per glucose), and choice C, Citric acid cycle, produces some ATP but not as much as the electron transport chain. Choice D is incorrect because different steps of cellular respiration produce varying amounts of ATP, with the electron transport chain being the most efficient in ATP generation.
