HESI Pediatrics Practice Exam
1. While teaching a parenting class to new parents, the nurse describes the needs of infants and toddlers regarding discipline and limit setting. What is the most important reason for implementing such parenting behaviors?
- A. Children need help in developing social skills.
- B. This age group fears loss of self-control.
- C. They provide the child with a sense of security.
- D. Children must learn to deal with authority.
Correct answer: C
Rationale: Implementing discipline and limit setting for infants and toddlers is primarily important as it provides them with a sense of security. This sense of security is crucial for their emotional and psychological development, helping them feel safe and supported as they explore the world around them. Choice A is incorrect because while developing social skills is important, the primary reason for discipline and limit setting in this context is to provide security. Choice B is incorrect as it does not address the main reason for implementing discipline and limit setting. Choice D is incorrect as the primary focus is not about dealing with authority at this early stage of development.
2. For the first 72 hours after thyroidectomy surgery, nurse Jamie would assess the female client for Chvostek's sign and Trousseau's sign because they indicate which of the following?
- A. Hypocalcemia
- B. Hypercalcemia
- C. Hypokalemia
- D. Hyperkalemia
Correct answer: A
Rationale: Chvostek's and Trousseau's signs are clinical manifestations that suggest hypocalcemia, a common complication following thyroidectomy. Chvostek's sign is elicited by tapping the facial nerve, resulting in facial muscle contraction, while Trousseau's sign is provoked by inflating a blood pressure cuff, leading to carpal spasm. Both signs are indicative of low calcium levels in the blood. Therefore, options B, C, and D are incorrect as they do not correlate with the signs specifically associated with hypocalcemia.
3. A client who has a flaccid bladder is placed on a bladder training program. Which instruction should the nurse include in this client's teaching plan?
- A. Use manual pressure to express urine
- B. Perform the Crede maneuver
- C. Apply an external urinary drainage device
- D. Take a warm sitz bath twice a day
Correct answer: B
Rationale: The correct answer is B: Perform the Crede maneuver. The Crede maneuver is a technique used to manage a flaccid bladder by applying manual pressure over the bladder area to assist in the expulsion of urine. This technique helps promote bladder emptying. Choice A is incorrect because using manual pressure to express urine is not a standardized technique and may cause harm. Choice C is incorrect as applying an external urinary drainage device does not address the need for bladder training. Choice D is unrelated to bladder training for a flaccid bladder.
4. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?
- A. To promote oxygenation by removing secretions.
- B. To reduce the amount of air trapped in the lungs.
- C. To increase the amount of carbon dioxide exhaled.
- D. To slow the respiratory rate and improve air exchange.
Correct answer: C
Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.
5. A 16-year-old adolescent with cystic fibrosis is admitted to the hospital with a respiratory infection. The nurse is teaching the adolescent about the importance of airway clearance techniques. Which statement by the adolescent indicates a need for further teaching?
- A. I should do my airway clearance exercises every day.
- B. I don’t need to do my airway clearance exercises if I feel okay.
- C. Airway clearance helps prevent mucus buildup in my lungs.
- D. I should continue my airway clearance routine even when I’m not sick.
Correct answer: B
Rationale: The correct answer is B. Airway clearance exercises are essential for individuals with cystic fibrosis to prevent mucus buildup in their lungs. It is crucial to perform these exercises regularly, even when feeling well, to maintain lung health and prevent complications. Choice A is correct as doing airway clearance exercises daily is necessary. Choice C is also accurate as airway clearance does indeed help prevent mucus buildup. Choice D is correct as it is important to continue the airway clearance routine even when not sick to maintain lung health. Choice B is incorrect because stating that airway clearance exercises are unnecessary when feeling okay demonstrates a misunderstanding of the importance of consistent airway clearance in cystic fibrosis management.
